A guide column 9 is convexly provided on the upper end surface of the lower clamping plate 2, and a guide sleeve 13 slidably matched with the guide column 9 is provided on the upper clamping plate 7.

[0024] There are two guide posts 9, which are symmetrically arranged on both sides of the transmission rod 4. The outer side of each guide post 9 is sleeved with a corresponding guide sleeve 13.

[0025] Grooves 15 are provided on the opposing surfaces of the lower clamping plate 2 and the upper clamping plate 7, a first anti-slip pad 8 is fixedly installed on the inner side of the upper groove 15, and a second anti-slip pad 10 is fixedly installed on the inner side of the lower groove 15, the transmission rod 4 is located between the two guide columns 9, the first anti-slip pad 8 and the second anti-slip pad 10 are both made of rubber material, and the first anti-slip pad 8 and the second anti-slip pad 10 can provide protection when the lower clamping plate 2 and the upper clamping plate 7 are clamped on the desktop, while improving the anti-slip ability.

[0026] During implementation, by rotating the handle 1, the transmission rod 4 connected to it is driven to rotate, and under the guiding action of the external thread 5, the transmission rod matching thread 12, and the guide column 9 and the guide sleeve 13, the upper clamping plate 7 is controlled to move downward, so that the upper clamping plate 7 and the lower clamping plate 2 are clamped on the table. The separate design of guidance and transmission makes the rotation more stable and the clamping is better without shaking. The upper clamping plate 7 is provided with a transmission rod matching thread 12, which can effectively realize the self-locking performance of the upper clamping plate 7 after movement, and the clamping is more stable and not easy to loosen, thereby improving the use effect.
