A holding fixture includes a first part, a securing member and a second part. The first part includes a first end face and a sleeve extending from the first end face, the sleeve defines a plurality of radial through holes each receiving a ball therein, and each ball has a diameter larger than the wall thickness of the sleeve therein. The securing member located around the sleeve includes a plurality of protrusions configured on an inner wall thereof, with every two neighboring protrusions defining a notch therebetween. The second part includes a body and a tail fixed on the body, with seating thereof in the sleeve enabled by an annular groove in the periphery thereof. The protrusions guide the balls into the annular groove to secure the second part on the first part.

Holding fixture

A stamping die () includes a base set (), a punch () detachably assembled on the base set, and a stripper plate () disposed on top of the base set. The stripper plate defines a through hole () through which the punch passes, and at least one elastic member () is disposed between the base set and the stripper plate. The stamping die can punch different shaped holes by means of changing the punch.

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.
