At the same time, the rectangular rod 23 will slide on the inner wall of the body 1, so that the two clamping rods 27 at the top of the rectangular plate 22 are located on both sides of the pipe, and then the motor is operated to drive the screw 26 to rotate, so that the two clamping rods 27 are on the outer surface of the screw 26 and the slide 2 5 moves in the same direction, clamping the two clamping rods 27 on both sides of the pipe respectively, and then operating the hydraulic rods of the pressing device and the piercing device to control the drill bit and the pressure block to move to press the tip and drill holes at both ends of the pipe respectively.
