Claims

[Claims for Utility Model Registration] 1. An upper piece and a lower piece are placed one on top of the other, and one side of the two pieces is connected to each other via an elastic part of a required height,
A holding part is formed between the two pieces for elastically inserting the extruded plate, and a circular fitting part is provided on the lower surface of the upper piece to fit into the pin hole of the extruded plate. A snap piece of an extrusion plate that is attached to a rotary die with the peripheral edge bent upward to form a finger hook. 2 An elastic part is formed on one side of the lower piece to be folded back toward the upper surface of the lower piece, and an engaging piece is provided at the tip of the elastic part to be elastically pressed against the upper surface of the lower piece,
The above-mentioned engagement piece and the lower piece sandwich the extrusion plate and are slidably attached to the extrusion plate, and the engagement piece is elastically fitted into the pin hole formed in the extrusion plate. In the snap piece of the extrusion plate attached to the rotary die to be engaged, the engaging piece is curved in a semicircular shape toward the lower side, and the radius of curvature on one side of the engaging piece is made larger than that on the other side. The structure is made smaller and the lower surface of the same piece is sloped like the outer circumferential surface of a truncated cone. 3 While opening a pin hole in the extrusion plate, attach a snap piece to the extrusion plate so that it can slide freely,
The snap piece is provided with an engaging piece that fits into the pin hole while being pressed into the pin hole, and a holding hole is provided at a predetermined distance from the pin hole in the extruded plate. A cutout is made between the holding hole and the pin through hole so that the outer diameters of both holes are approximately gourd-shaped, and the engaging piece is made to be able to slide freely between the pin through hole and the holding hole. The feature is the sliding structure of the step piece on the extrusion plate attached to the rotary die.
