[0010] In a preferred embodiment, limit rods are fixedly installed on both sides of the top of the pressure plate. The top of the limit rods passes through the slide plate and extends to the outside of the slide plate. The slide plate has a circular hole for the limit rods to pass through.

[0011] By setting a limit rod, the pressure plate can be limited during use, preventing it from shaking when the threaded rod rotates, thus maintaining the pressure plate's linear up and down movement and improving the ease of use of the device.

[0012] In a preferred embodiment, anti-slip plates are fixedly installed on both sides of the bottom of the pressure plate, and anti-slip grooves are provided on the bottom of the anti-slip plates. An abutment plate is fixedly installed on the bottom of the pressure plate between the two anti-slip plates, and the bottom of the abutment plate contacts the inner bottom wall of the groove.

[0013] By incorporating anti-slip plates, the fit between the card and the pressure plate is increased during use, preventing slippage during positioning and maintaining the card's positioning stability.

[0014] In a preferred embodiment, a rotating disk is fixedly mounted on the top of the threaded rod, and a handle is fixedly mounted on the surface of the rotating disk, with anti-slip textures on the surface of the handle.

[0015] The rotating disc and handle allow for easy rotation of the threaded rod during use, facilitating tightening and loosening later. The handle also makes it easy for operators to hold and operate the rod.

[0016] In a preferred embodiment, a handle is fixedly installed at one end of the guillotine, and an anti-slip sleeve is fitted on the surface of the handle, with the inner wall of the anti-slip sleeve fitting against the surface of the handle.

The bottom of the threaded rod 8 is rotatably connected to a pressure plate 9 through a bearing. Limiting rods 13 are fixedly installed on both sides of the top of the pressure plate 9. The top of the limiting rod 13 passes through the sliding plate 7 and extends to the outside of the sliding plate 7. A round hole is provided on the sliding plate 7 for the limiting rod 13 to pass through. The limiting rod 13 can limit the pressure plate 9 during use and prevent the pressure plate 9 from shaking when the threaded rod 8 rotates, thereby keeping the pressure plate 9 moving up and down in a straight line and improving the ease of use of the device. A rotating disk is fixedly installed on the top of the threaded rod 8. A handle is fixedly installed on the surface of the rotating disk. The surface of the handle is provided with anti-slip texture. The rotating disk and handle make it easy to rotate the threaded rod 8 during use, which facilitates tightening and loosening during subsequent use.
