[0036] Technical features and working principle

[0037] First, the mold head is inserted into the triangular protrusion 6 of the mold head slot 5 through the triangular groove 4 on the bottom surface of the lower mold 3, and is flexibly moved to a suitable drilling position. The positioning pin 25 is extended by the small spring 24 and pushed into the corresponding positioning groove 28 to form a positioning.

[0038] Furthermore, the product that needs to be punched is placed into the rectangular groove 2 that is laterally arranged on the front side of the upper mold 1, and the punching position is determined by the distance scale 27 on the top surface of the upper mold 1.

[0039] Furthermore, by holding the lower handle 8, the lever 18 at the front end of the lower handle 8 moves downward within the racetrack-shaped through hole 17, causing the rear end of the rocker arm 15 to move downward, and the front end of the rocker arm 15 to move upward through the center hole 29 of the mold head slot 5, causing the corresponding slider 13 to move upward within the corresponding positioning groove 14, causing the corresponding cutter head 11 to pass through the product and complete the drilling;

[0040] Furthermore, when the lower handle 8 is released from the grip, the long leg of the long leg spring 20 returns the lower handle 8 to its downward position;

[0041] Furthermore, the front end of the rocker arm 15 moves downward synchronously, and the large spring 12 extends to reset the corresponding slider 13 and the cutter head 11 downward.
