Abstract

The invention discloses an elastic piece pulling head and relates to the field of self-locking pulling heads capable of automatically rebounding. The elastic piece pulling head comprises a pulling head base, a pulling plate, a connecting shaft and an elastic piece, the pulling head base is provided with a semicircular concave face concaving downward and an arc-shaped concave face concaving downward, the elastic piece is arranged in the arc-shaped concave face, a rotating portion and a stopping portion are arranged at the top end of the pulling plate and are in left-right adjacency, the rotating portion is provided with a cambered face, and the stopping portion is provided with a protruding corner higher than the cambered face. The elastic piece is a rectangular piece and is arranged in the arc-shaped concave face of the pulling head base, and when the pulling plate is laid flatwise, the rotating portion is abutted against the elastic piece which is in a slightly bent state. By using the elastic piece pulling head, automatic rebounding of the pulling plate after being pulled to be close to 90 degrees can be realized, and a zipper can be automatically locked to prevent the pulling head from sliding when not in use; even if being damaged, the elastic piece does not shed from the pulling head.

Description

technical field [0001] The invention relates to the field of zippers, in particular to a slider that can automatically rebound for a pull tag. Background technique [0002] In the slider for zipper with automatic locking device, the hook structure is usually used to realize the function of automatic rebound of the card. Patent 103220932A discloses a slider for zipper with automatic braking device. The slide fastener slider of the stopper device includes: a main body formed with a fastener element guide passage through which the fastener elements can penetrate; It has a locking claw protruding from a locking window hole formed in the above-mentioned main body into the above-mentioned chain element guide passage; a force applying part that applies force to the above-mentioned locking member so that the above-mentioned locking claw is released from the above-mentioned locking window hole Protruding into the above-mentioned chain element guide passage, the slider for a slide fa...
