The present invention provides a connector and a fixing structure for fixing the connector to a supporting member. The connector has a housing including a plurality of terminal receiving portions. The housing has a pair of rail portions projecting from both side walls of the housing, a pair of arm portions vertically extending from the both side walls downward and formed in U-shape, and a stopper projecting from a bottom wall of the housing. When the housings having the same structure are laminated up and down, the pair of the rail portions of the lower housing are respectively sandwiched between the pair of the arm portions of the upper housing, and the stopper of the upper housing abuts on a rear end of an upper wall of the lower housing.

A syringe assembly (10) has a syringe barrel (12), a plunger rod (14) and stopper (16), wherein the syringe barrel has an open end receiving the plunger rod and stopper in a sliding direction. The plunger rod includes a shaft (52) having a longitudinal axis with a first end having a coupling member (62) for coupling with the stopper. The shaft has a least one plunger rod support (82) extending radially outer from the shaft and spaced from the first end for cooperating with an inner surface of the syringe barrel (12) to resist lateral movement and tilting of the plunger rod relative to the longitudinal axis of the axial passage of the syringe barrel. The shaft in one embodiment has at least two spaced apart points of support (41) and (82) for maintaining the axis of the plunger rod on axiswith the syringe barrel to limit twisting and tilting of the stopper thereby resisting distortion of the stopper that can cause leakage.

The invention discloses a tool for rapid press fitting of a planetary shaft. The tool comprises a hydraulic machine and a workbench top and further comprises a support connected to the workbench top, a pressing plate connected to the top of the support, and a fastener. One end of the fastener penetrates the pressing plate, and the fastener is connected with the pressing plate. A gap is formed between the bottom of the fastener and the upper large circle end face of a planet carrier, and it can be ensured that the upper large circle end face of the planet carrier is moved into the position below the fastener through the gap. When the fastener inclines on the planet carrier, the fastener abuts against the upper large circle end face, the inclination degree of the planet carrier is limited, and it is ensured that the planetary shaft is pressed in a planet hole. According to the tool, assembly of the planet carrier can become easy and fast, and therefore the labor intensity of workers is lowered, and the production efficiency is improved.

The invention discloses an ultra-lightweight wheel with an adjustable balance structure, relates to the technical field of ultra-lightweight wheels, and specifically relates to an ultra-lightweight wheel with an adjustable balance structure, including a rim, the front end of the outer wall of which is provided with a concave The middle part of the front end of the rim is provided with a spoke, and the outer wall of the spoke is connected with a support plate, the inside of the support plate is provided with a through groove, and the inside of the through groove is penetrated by a balance adjustment mechanism, and the inner wall of the spoke is provided with screw holes. The limit groove plate and connecting spring provided by the ultra-lightweight wheel with an adjustable balance structure, the limit groove plate can effectively approach each other along the axial direction of the frame, and the limit groove plate can be placed inside the frame, which can Effectively reduce the space occupied by the frame, and the limit slot plate can be effectively pushed out of the frame by connecting the spring, and the limit slot plate and the support plate can be engaged, so that the frame can be effectively restricted The location can effectively improve the convenience of disassembling the frame.

The invention relates to aweak geology open caisson construction method. The weak geological open caisson construction method specifically includes the following steps: S1, an excavation site is preliminarily leveled, then formwork erecting pouring of the first section of an open caisson is conducted, and then excavation and sinking construction of the first section of the open caisson is conducted; S2, soil on the periphery of the first section of the open caisson is excavated and the outer wall of the open caisson is covered with a layer of demolding material, and then concrete is poured onthe periphery of the first section of the open caisson to form a correction platform; S3, formwork erecting pouring of the second section of the open caisson is conducted on the first section of the open caisson, and then excavation and sinking construction is conducted; and S4, the method of open caisson construction in the step S3 is conducted repeatedly until the overall height of the open caisson reaches the design depth, a plurality of water leading holes are reserved in the lower open caisson during vertical shuttering pouring, the open caisson is subjected to bottom sealing construction, finally, load-bearing concrete is poured on the periphery of the top open caisson which is higher than the correction platform, and the open caisson capable of being applied in weak geology is obtained. According to the weak geology open caisson construction method, the open caisson can be sunk vertically, the construction accuracy is high, and whole sinking of the open caisson is not prone to happening.

The invention relates to the technical field of medical instruments and provides an instrument for holding files. It includes: a hammering block, a main body, a handle, shrapnel, a slider and a hook; one end of the main body is provided with a hammering block, and the hook is composed of a hook 1 and a hook 2, and the hook 2 is located at The other end of the main body; the main body is connected to the handle through pin two, and the handle is connected to one end of the elastic piece through pin one; the other end of the elastic piece is connected to the slider and the said elastic piece through pin three hook 1; the main body is provided with a limiting structure. During the opening and closing process of the handle, the shrapnel is driven to stretch and deform, and the slider and the hook connected to it are driven to move along the limiting structure. The first hook and the second hook on the main body always move linearly in the same plane. The beneficial effect of the present invention is that: during the opening and closing process of the handle, the hook moves in one direction, which ensures the convenience and speed of clamping the file, saves operation time, and improves operation quality.

The invention discloses an ultra-light wheel with a balance adjusting structure, and relates to the technical field of ultra-light wheels. In particular, the ultra-light wheel with the balance adjusting structure comprises a rim, a groove is formed in the front end of the outer wall of the rim, spokes are arranged in the middle of the front end of the rim, and support plates are connected to the outer walls of the spokes; and through grooves are formed in the support plates, balance adjusting mechanisms penetrate through the interiors of the through grooves, and screw holes are formed in the inner walls of the spokes. According to the ultra-light wheel with the balance adjusting structure, limiting groove plates and connecting springs are arranged, the limiting groove plates can be effectively close to each other in the axial direction of a shell frame, the limiting groove plates can be placed in the shell frame, and therefore the space occupied by the shell frame can be effectively reduced; and the limiting groove plates can be effectively pushed out of the shell frame through the connecting springs, so that the limiting groove plates and the support plates can be clamped, the position of the shell frame can be effectively limited, and the convenience of disassembling and assembling the shell frame can be effectively improved.
