The utility model discloses a minimally invasive pedicle screw connecting rod taking-out instrument, and relates to the field of medical instruments, and the minimally invasive pedicle screw connecting rod taking-out instrument comprises a handheld part, a sleeve, an ejector rod, an ejecting piece and an elastic piece; in the working process, the screw connecting rod is sleeved with the lantern ring, the ejector rod is rotated, the ejector rod overcomes the elastic force of the elastic piece to eject the jacking piece outwards to the lower end of the sleeve, and the jacking piece abuts against the screw connecting rod arranged in the lantern ring in a sleeved mode so that stable connection between the jacking piece and the screw connecting rod can be achieved; only one small sleeve is needed for operation at the wound position, an operative incision does not need to be enlarged, stable connection with the screw connecting rod can be guaranteed in a threaded abutting mode, and the screw connecting rod is prevented from falling off in the taking-out process.

The utility model relates to the field of batteries, and provides a plastic component, a cover plate and a battery. The plastic component comprises a first plastic body; a first elastic connecting part is arranged at one end, facing the second plastic body, of the first plastic body, a second elastic connecting part is arranged at one end, facing the first plastic body, of the second plastic body, and the first elastic connecting part and the second elastic connecting part are connected with each other. The plastic component can obviously improve the production efficiency and reduce the production cost; the first plastic body and the second plastic body which are elastically connected enable the whole plastic assembly to be attached to the cover plate more tightly, and the problem of plastic droop is avoided; as the elastic connecting part has elasticity, the elastic connecting part can adapt to the change and vibration of external force to a certain extent.

The utility model relates to the technical field of gluing devices, and discloses a gluing device for insulation paper production, which comprises a base, the surface of the base is fixedly connected with two groups of symmetrically arranged side plates, the side walls of the two groups of side plates are provided with through holes, connecting shafts are rotatably connected in the through holes, a gluing assembly is arranged between the two groups of connecting shafts, and the gluing assembly is connected with the base. And the gluing assembly comprises an inner cylinder, the inner cylinder is fixedly connected between the two sets of connecting shafts, and a plurality of sets of glue outlet grooves distributed in an array mode are formed in the outer wall of the inner cylinder. According to the gluing device for insulation paper production, rapid splicing and splitting are achieved through the two sets of semicircular cylinders by means of protruding strips, grooves and magnetic strips, it is guaranteed that the semicircular cylinders are stably connected during gluing through elastic positioning of springs, telescopic rods and positioning pins in the positioning assemblies, positioning is rapidly relieved by pressing lantern rings, and the gluing efficiency is improved. Residual glue of the sponge layer or the inner cylinder and the semicircular cylinder can be conveniently cleaned and replaced, and the time cost and the operation difficulty of equipment maintenance are reduced.

The utility model discloses a special superspeed servo motor double cooling cavity shell for glass polishing, particularly relates to the technical field of servo motor shells, and comprises a shell, one end of the shell is provided with an end cover, the other end of the shell is provided with a protective cover, and the middle part of the shell is provided with a first cooling cavity. According to the utility model, the cooling liquid circularly flows among the second cooling cavity, the first cooling cavity and the heat exchange cavity under the driving of the liquid pump, the double-cooling-cavity structure is combined with the heat conduction strips, the heat conduction rings, the heat dissipation fin rings and other parts to form an all-dimensional and multi-layer heat dissipation system, the first cooling cavity directly cools the core parts of the motor, and the second cooling cavity directly cools the core parts of the motor. The heat conduction strips rapidly conduct heat, the heat exchange cavities achieve heat exchange of cooling liquid, the cooling fin rings and the fan blades enhance the air cooling effect, multiple heat dissipation modes are in synergistic effect, the heat dissipation efficiency is greatly improved, the running temperature of the motor can be rapidly and effectively reduced, and the stability and reliability of the motor in ultra-high-speed running are guaranteed.

The utility model discloses an assembly type photovoltaic support fixing clamp relates to fixing clamp technical field, include: U -shaped clamp, photovoltaic support stand, fastening bolt and stand bottom plate, the photovoltaic support stand is located the top of stand bottom plate, the top of stand bottom plate is installed with stand stiffening rib a, the top of stand bottom plate is installed with stand stiffening rib b, the outer wall of U -shaped clamp is installed with limit and anti -fall bolt. The utility model discloses through being installed with clamp mechanism, will U -shaped clamp along house steel beam upper flange by from outside to inside and enter, make stand bottom plate and house steel beam upper flange all be in the U -shaped groove of U -shaped clamp, ensure that the inside of U -shaped clamp lower steel plate with house steel beam upper flange contact surface maximum, alternately tighten two fastening bolts on each U -shaped clamp, while U -shaped clamp lower steel plate and house steel beam upper flange top tight, and U -shaped clamp will not move to the outside of steel beam and lead to U -shaped clamp fastening force weakening or failure.

This utility model provides a semi-hermetic refrigeration compressor body cover with an exhaust needle, relating to the field of semi-hermetic refrigeration compressor technology. It includes a cover assembly consisting of a cover body and four rotating seats arranged in a ring on the cover body. It also includes an exhaust assembly consisting of an exhaust seat fixedly connected to the top of the cover body and a threaded seat. A rubber plug is installed inside the exhaust seat, and a through hole is opened at the top of the rubber plug. Through the exhaust assembly, the exhaust seat and the threaded seat cooperate to form an exhaust channel. The inclined through holes of the rubber plug are arranged in a ring, with the angle decreasing from top to bottom towards the center. This design allows the gas to form a converged and then dispersed flow path during exhaust, ensuring smooth exhaust and achieving dynamic sealing through the elasticity of the rubber plug itself, reducing gas leakage. The inclined structure also reduces airflow impact, improves exhaust stability, and enhances overall sealing and exhaust performance.
