Abstract
A punching assembly includes a die base, a sleeve, an adjusting screw, a pull portion, a latching block, an elastic element, a fixing ring and a stop member. A top of the die base is received in the sleeve. The adjusting screw includes a contact end, a mounted end inserting into the sleeve and connecting to the top of the die base, and a latching portion located between the contact end and the mounted end. The pull portion is disposed around the sleeve. The latching block engages the latching portion. The elastic element is disposed around the adjusting screw, supporting the latching block. The fixing ring surrounding the adjusting screw is fixed on the sleeve. The stop member, contiguous with the fixing ring, prevents axial movement of the adjusting screw.
