When using the clamping device, it is not convenient to position doors and windows of different sizes. At the same time, the position of doors and windows is fixed and cannot be adjusted, which is inconvenient when processing at different positions is required.

[0003] In the prior art, the clamping device is composed of a clamping mechanism, a transmission mechanism, and an adjustment mechanism. When processing a window, the window is placed on a placement plate in the clamping mechanism, and the clamping mechanism is moved to a suitable position through the operation of the motor of the transmission mechanism.

During the processing, the profiles are prone to warping, affecting the processing accuracy. Therefore, a clamping device is proposed to address the above problem. Utility Model Content

A motor A is fixed at one end of the workbench, and a bidirectional screw A is installed on the rotating shaft of the motor A. Slide blocks A are slidably arranged at both ends of the bidirectional screw A.
