In this way, when the solution is replaced for the patient with peritonealdialysis, people only operate the peritoneal dialysis solution drainage tube, operation and control are convenient, the hand does not easily shake, and accordingly the probability of contamination under the condition that the threaded connector of the peritoneal dialysis external connection short tube and the connector of the peritoneal dialysis solution drainage tube are touched by external substances or the outer walls of the threaded connector and the connector touch each other can be effectively lowered; the height of the lifting support is adjustable, and therefore the fixing device adapts to patients of different heights for usage, and is good in using effect.

A combined anti-shock socket, including a socket part, a shell part, and a plug part; the socket part and the plug part are installed inside the shell part, and the socket part is installed on the side of the plug part and connected with the plug part; the three The composed units can be used in combination; the socket combination function is realized; the unique locking structure of the socket part can realize that when a non-plug object is inserted, the socket does not conduct electricity, realizes the function of preventing electric shock, and greatly enhances safety.

The invention discloses a rock core inner tube salvager of a submarine drilling rig rope coring drilling tool. The rock core inner tube fisher of the submarine drilling rig rope coring drilling tool includes a salvage wire rope, an anti-clamping mechanism, a weight rod, a pressure rod, a fixed guide tube, a rotary core clamp sleeve and steel balls; the salvage wire rope is connected with the anti-clamping mechanism; the weight rod is fixed to the lower end of the anti-clamping mechanism, the pressure rod is fixed to the lower end of the weight rod and arranged in an inner cavity of the fixed guide tube, a plurality of pressure rod oblique teeth are arranged at the lower end of the pressure rod, and a guide groove is formed in the side surface of the pressure rod; a guide key is arranged onthe side wall of the inner cavity of the fixed guide tube, and the guide groove and the guide key form guide matching; the rotary core clamp sleeve is placed in the fixed guide tube, a steel ball seat is fixed to the bottom of the fixed guide tube, a plurality of steel ball holes are formed in the side wall of a circular column of the steel ball seat, and one steel ball is arranged in each steelball hole; and the rotary core clamp sleeve moves downwards to enable the steel balls to move towards the center of the circular column. According to the rock core inner tube fisher of the submarine drilling rig rope coring drilling tool, 'clamping' and 'releasing' can be extremely conveniently carried out on a rock core inner tube salvage spearhead, and the rock core inner tube fisher of the submarine drilling rig rope coring drilling tool further has the advantages of simple and compact structure and convenient handling.

The invention relates to an extruding and self-locking type automatic two-grade telescoping rod structure. The extruding and self-locking type automatic two-grade telescoping rod structure comprises abase, wherein one end of a first lead screw is rotatably connected into the base, and the first lead screw can rotate along own axis; a first gear provided with a threaded hole sleeves the outer partof the first lead screw; the first lead screw penetrates through a threaded hole in the first gear; the first gear is rotatably mounted into a supporting plate; a second gear and a third gear are rotatably mounted in the supporting plate; the first gear is correspondingly engaged with the second gear and the third gear; the second gear is provided with a threaded hole, and a second lead screw which penetrates through the second gear and the supporting plate is formed in the second gear; the second gear is fixedly connected to a third lead screw; and the third lead screw extends in the direction far away from the base. According to the extruding and self-locking type automatic two-grade telescoping rod structure, two telescoping rod joints are driven to sequentially telescope through one motor, and a plurality of telescoping rod sections can be positioned while the telescoping rod telescopes, and manually operating a damping part or a positioning part is avoided; and the extruding andself-locking type automatic two-grade telescoping rod structure is convenient and quick.

The invention provides a joint-adjustable precision parallel external fixator. The external fixator has six degrees of freedom, including a proximal fixing ring, a distal fixing ring, three connecting rods, a ball joint, a Kirschner wire, and a needle clamp. . The length of the connecting rod is adjusted by the worm and worm, and a rotating drive pair composed of a pair of bevel gears is set at the distal fixed ring to adjust the angle of the ball joint relative to the distal fixed ring, thereby changing the pose of the distal fixed ring and completing the three-dimensional deformity correction. Each ball joint in the present invention can realize independent adjustment and locking, so as to make up for the problem that the range of swing angle of the ball joint is small. The three connecting rods use worm gears to adjust their lengths, and the rotation of the worm knob is converted into a small change in the length of the connecting rods, so as to avoid drastic changes in the length of the connecting rods caused by human errors and other factors, and avoid unnecessary damage.

The invention provides an energy-saving economizer for exchanging fresh air for an air conditioner, and the energy-saving economizer comprises a shell; an air door is arranged at the ventilating side of the shell; a left mounting hole and a right mounting hole are respectively and symmetrically arranged on fixed plates at the two ends of the shell; the two ends of the air door are respectively and movably connected with the shell by virtue of the left mounting hole and the right mounting hole; and a button used for opening and closing the air door is arranged at the outer side of one end of the air door. The fresh air can be exchanged by manually opening the air door of the economizer, so that the energy-saving working mode of still refrigerating when a compressor of an air-conditioning system is stopped can be realized; and the energy-saving economizer has the advantages of being low in cost, energy-saving and environmentally-friendly.
