[0017] Beneficial effects of this application:

[0018] 1. The servo motor drives the lead screw to rotate. Since the front and rear outer walls of the lead screw are respectively provided with left-handed and right-handed threads, the two U-shaped fixings can be driven to move toward or oppositely, thereby adjusting the distance between the two U-shaped fixings, so as to fix aluminum veneers of different sizes. Then, the two sides of the aluminum veneer are placed inside the two U-shaped fixings, and the electric cylinder drives the pressing plate to move downward to fix the aluminum veneer. The extension of the U-shaped fixing can make the fixing point of the aluminum veneer closer to the punching point, thereby increasing the stability and accuracy of the punching process.

[0019] 2. The small gear is driven to rotate by servo motor 2.
