This utility model discloses a cable cutting clamping device, including a base plate and a motor installed on the right side of the base plate. A sliding groove is formed on the rear top of the base plate, and a threaded rod is rotatably connected inside the sliding groove. The threaded rod is connected to the output end of the motor, and a moving block is threadedly connected to the outer end of the threaded rod. The moving block is slidably connected to the sliding groove. An electric telescopic rod is connected to the top of the moving block, and a fixed block is connected to the front end of the electric telescopic rod. Rotating plates are rotatably connected to the upper and lower sides inside the fixed block. A rotating block is rotatably connected to the end of the rotating plate away from the fixed block, and a movable block is connected to the end of the rotating block away from the rotating plate. The movable block is slidably connected to the base plate. Through the linkage structure formed by the base plate sliding groove, the threaded rod, and the motor-driven moving block, it can flexibly adapt to cables of different thicknesses, accurately adjust the clamping range and force, prevent damage to thin cables and slippage of thick cables, improve cutting accuracy, reduce safety hazards, reduce manual component replacement, and improve work efficiency.

The application provides an orthodontic traction device and belongs to the field of oral orthodontic instruments. The device solves the problem of poor cross-segment stability and unreasonable orthodontic stress of the existing orthodontic traction device. The device comprises sliding support parts which are connected to one side end face of a connecting support assembly and are used for cross-segment sliding connection on a straight wire arch in cooperation with the connecting support assembly to lock the straight wire arch under preset conditions. A multi-curve traction hook is connected to the side end face of the connecting support assembly away from the sliding support parts and is used for connecting a traction member. The device is mainly used for tooth orthodontic traction.

The utility model is suitable for elevator brake technical field provides an elevator brake fault monitoring devices, include: elevator brake, the device moves through connecting rod drive push board, push the connecting plate one, connecting plate two and shade slide of shading mobile subassembly and move, a plurality of ball groove and ball body on shade slide reduce the sliding resistance, avoid the device to slide to deviate, improved detection accuracy.

This utility model relates to the field of quartz crucible wall thickness detection technology, specifically a quartz crucible wall thickness detection and calibration device. It includes a working plate and a quartz crucible. Several support columns are fixed on the bottom surface of the working plate. The quartz crucible is located above the working plate, and a pneumatic chuck for clamping the quartz crucible is installed near the center of the top surface of the working plate. The device also includes a detection mechanism for detecting the wall thickness of the quartz crucible. The detection mechanism includes a frame fixed to the top surface of the working plate, a movable plate slidably connected to the bottom surface of the frame's horizontal plate, an electric cylinder mounted on the outer wall of the movable plate, and a right fixed plate fixed to the piston rod of the electric cylinder via a right fixed rod. This utility model solves the problems of traditional detection devices being difficult to adapt to quartz crucibles of different sizes and having poor clamping stability by setting up a pneumatic chuck. It also solves the problems of large errors, low efficiency, and time-consuming and labor-intensive manual measurement of quartz crucible wall thickness by setting up a detection mechanism.
