The two limit frames are symmetrically arranged. The movable frame is slidably connected between the two limit frames. Reset springs are connected between the movable frame and the two limit frames. A push plate is installed on the top of the movable frame.

[0009] Furthermore, the push plate is located in the blanking hole on the mounting plate, and the top of the push plate contacts the bottom of the metal plate.

[0010] The beneficial effects of the utility model are as follows: the telescopic rod of the electric push rod extends out to push the punching head to move downward, and the fixed plate, the movable rod, the pressure plate, the support spring and the friction plate move downward accordingly, and the pressure plate presses the position of the metal plate where holes need to be punched to avoid deformation of the metal plate when the punching head is punching, and the friction plate is used to fix the metal plate to avoid movement of the metal plate when the punching head is punching, thereby improving the stability of the metal plate during punching.
