When the punch 4 is connected to the mounting head 11 by a threaded connection, the end surface of the punch 4 abuts against the surface of the ball 623, squeezing the ball 623. The return spring 622 is squeezed, so that a gap is generated between the ball 623 and the valve tube body 621. The lubricating liquid flows from the inside of the valve tube body 621 into the inside of the mounting head 11. The surface of the punch 4 is flowing with lubricating liquid, which achieves the lubrication effect, improves the punching die efficiency, and protects the punch 4.

A threaded section is provided on the top of the surface of the punch 4, and an internal thread is provided on the inner diameter of the mounting head 11. The length of the threaded section of the punch 4 is greater than the length of the internal thread of the mounting head 11, so that the punch 4 can be threadedly connected to the mounting head 11 to achieve a stable connection. At the same time, the end of the punch 4 can abut against the end of the mounting head 11 until it abuts and squeezes the ball 623, so that the lubricating liquid can enter the interior of the mounting head 11. After the lubricating liquid is concentrated inside the mounting head 11, the lubricating liquid can soak the circumference of the punch 4 and evenly penetrate the mounting head 11 from the outer surface of the punch 4, so that the lubricating liquid on the surface of the punch 4 is evenly arranged, thereby improving the punching efficiency of the punch 4 and providing all-round protection for the punch 4.
