and thirdly, punching, namely driving the sliding plate (22) to move along the sliding chute (23) through the screw rod (24), pushing the punching head (32) to reach a hole to be punched through the lifting cylinder (31) when the sliding plate (22) moves to the top end of the body of the patient, and punching through the punching head (32).
