The invention relates to a portable capillary electrophoresis apparatus, which comprises a sampling introducing system, an optical detecting system, a high-voltage power source, a photoelectric converting unit and a signal processing unit, wherein, the sampling introducing system comprises a base and an upper baffle is arranged at one side of the base, a positioning guide rail with a plurality ofpositioning slots is fixedly connected with the other side of the base; a sleeve barrel is fixedly connected with a top slab of a slide frame that is arranged between the base and the upper baffle, an upright post which is provided with a positioning pin that is arranged in the axial direction and inserted into a slotted hole in a middle part of the sleeve barrel is arranged inside the sleeve barrel, a spring is arranged between a base of the upright post and the top slab of the slide frame, a tray with a millipore plate is fixedly connected with the top of the upright post, a positioning pinthat is matched with the positioning slot is arranged on the tray, and two detecting electrodes and two ends of a capillary are fixed above the base through a clamping holder; wherein, the power source of the optical detecting system adopts a pen-typed mercury lamp, and other units in the system all adopt existing techniques. The portable capillary electrophoresis apparatus has wide application range and convenient portability, and can implement the detection of various reagents.

The invention relates to a binder and a file for simplifying operation when opening a binding pole. Provided is a binder (1), which is constituted to comprise a first operation portion (41) adapted to be displaced, in response to a pushing operation, from an unlock position, at which a binding lever (3) is opened, to a lock position, at which the binding lever (3) is closed, a holding mechanism (43) for holding the first operation portion (41) having reached the lock position, at this lock position, and a second operation portion (42) adapted to release, in response to the pushing operation, the holding of the first operation portion (41) by the holding mechanism.

The invention discloses an ultrasonic scalpel with a variable scalpel bar connection mode, and belongs to the technical field of ultrasonic scalpels. The ultrasonic scalpel comprises an ultrasonic scalpel body, wherein an adjusting mechanism is arranged on the outer side of the ultrasonic scalpel body, one end of the adjusting mechanism is fixedly connected with one end of a pushing mechanism, and the other end of the pushing mechanism is fixedly connected to the upper surface of a fixing shell. According to the ultrasonic scalpel, a mounting mechanism is arranged, when arc-shaped plates are pushed to move towards the position between two stop blocks under the action of the arc-shaped plates, under the action of arc surfaces, the two arc-shaped plates get close to each other and move to the position between the two stop blocks when being extruded, at the moment, two stop plates penetrate through the stop blocks to move into the fixing shell, sliding plates can be clamped into plate grooves at the moment, and the scalpel bar is limited and cannot shake front and back under the actions of the sliding plates and the plate grooves; and by arranging first springs, when the arc-shaped plates are not extruded any more, the first springs open two positioning plates through the elasticity of the first springs, and at the moment, the sliding plates can move and are smoothly clamped into the plate grooves.

The invention relates to the field of concave-convex advertising board printing devices, in particular to a concave-convex advertising board printing device. The concave-convex advertising board printing device comprises a main body, a discharging port, a material transferring mechanism, a flattening mechanism, a conveying mechanism, a printing mechanism, an opening and closing mechanism and a limiting mechanism. Materials needing to be printed with concave-convex characters can be conveniently transferred to a next stage one by one through the arrangement of the material transferring mechanism, flattening and straightening treatment can be conducted on the raw materials through the arrangement of the flattening mechanism, edge warping of the printed materials is avoided, and the adjusted materials can be conveyed to the bottom end of the printing mechanism through the arrangement of the conveying mechanism. Through the arrangement of the printing mechanism, materials conveyed by the conveying mechanism can be conveniently pressed, through the arrangement of the opening and closing mechanism, when the main body is idle, a filling opening of the main body can be shielded, dust is prevented from entering the main body, and through the arrangement of the limiting mechanism, a shielding part can be automatically limited. The working process is prevented from being influenced by accidental sliding of the shielding part, and the use effect of the main body is improved.

The invention discloses an attachable core-driven double-head powder shaft sleeve pickup. The attachable core-driven double-head powder shaft sleeve pickup is characterized by comprising a pickup part and a handle part. The pickup part is provided with a chuck and an elastic yarn. The handle part is provided with a core rod, the outer diameter of which is equal to that of a casing pipe. The upper end of the core rod is connected to a button, a threaded joint connected to a threaded connector is arranged at the lower end of the core rod, the lower end of the threaded joint presses the upper end of the casing pipe, a holding pipe externally sleeves the casing pipe and the core rod, a retraction edge is arranged at the inner edge of the lower end of the holding pipe, a boss is arranged on the upper part of the core rod, a compression spring sleeving the core rod is arranged between the boss and the retraction edge, a radial shaft is connected to the core rod above the compression ring, a longitudinal limiting chute is arranged on the side wall of the holding pipe, the end head of the radial shaft fits the longitudinal limiting chute, an ejector pipe is connected to the lower end of the holding pipe in a locking manner, a bottom plate is arranged at the lower end of the ejector pipe, and an opening where an stretch yarn extends downward is arranged on the bottom plate; the handle disclosed by the invention is easy to hold, the pressing operation is more convenient, and the handle is more stable and little to jitter if being released.
