Description

technical field [0001] The invention relates to a zipper puller, in particular to a self-locking zipper puller. Background technique [0002] Existing zipper sliders can be roughly divided into self-locking zipper sliders and non-self-locking zipper sliders. Non-self-locking zipper sliders may slide along the zipper tape under non-human conditions, while self-locking zipper sliders can prevent sliding under non-human operating conditions through a specially designed self-locking mechanism. For example, U.S. Patent No. 3,952,379 issued on April 27, 1976 discloses a self-locking zipper puller, which includes a slider body, a hook and a pull tab. The slider body includes an upper wing plate, a lower wing plate and a connecting column, the horse hook is arranged on the upper wing plate, and the pull rod of the pulling piece is arranged between the horse hook and the upper wing plate of the slider body . When the pull piece is turned over, the pull bar of the pull piece can pr...

Problems solved by technology

In order to prevent the pull rod of the pull piece from being dislocated during the rotation process, the pull rod of the pull piece must be fixed with a fixing device, and then the horse hook can be placed on the pull rod of the pull piece, and finally the horse hook can be placed on the pull rod by a riveting mechanism. hook, which makes the assembly of the zipper puller quite complicated
