Through the worm wheel 18, transmission shaft 17, first bevel gear 19, and multiple second bevel gears 20, the corresponding moving screw 11 rotates. This causes the corresponding moving slider 12 to move with the fixing clip 13 and disengage from the fixing slot 14, thereby releasing the fixing restriction on the punch 3 or die 4, allowing it to be removed. For subsequent installation, simply insert the corresponding mounting plate 7 into the mounting slot 8, and then rotate the knob 21 to move the fixing clip 13 and engage it in the fixing slot 14. 4. Installation and fixing can be completed quickly and easily. During this process, the spring clip 24 corresponds to and engages with the positioning slot 27, thereby further locking the knob 21 and improving stability. Finally, regarding the use of the die 4, after the inverter housing is stamped, the operator can press the button 37 to move the pressing rod 34 with the second abutment 36, which in turn moves the spring plate 29 upward via the first abutment 31, thus ejecting the inverter housing inside the die 4. This facilitates quick material removal by the operator. After releasing the button 37, the spring plate 29, the first abutment 31, the second abutment 36, and the pressing rod 34 are reset by the reset spring 35 and the spring plate 29 itself, so that they can be used again later.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
