Set up the guide inclined plane and match with the installation inclined plane, can move along the fitting surface when the pulling-on piece pulling locking shell fragment warp, make locking portion break away from and reset and realize the locking function.
Furthermore, the bottom of the embedded groove is provided with a disassembly groove corresponding to the positioning groove.
The extracting tool passes through the detaching groove and acts as the activity space with the constant head tank, presses down the fastening shell fragment and can make the locking shell fragment break away from the embedded groove, convenient to detach.
Furthermore, the front end of the pulling piece is provided with a mounting ring, and the elastic part arches upwards and forms a mounting ring accommodating space with the pulling head.
The utility model discloses a set up the locking shell fragment and play the locking effect to the zipper head, the locking shell fragment passes through the fixed part to be connected with the pull head, carries out elastic deformation through the elastic component and makes locking portion reciprocate to realize locking portion to the locking of zipper head and the function that loosens. The installation is simple convenient on structural design, and reduction in production cost and raise the efficiency stimulate the pulling-on piece and can realize the deformation of locking shell fragment on using, realize the function of locking and loosening, and is simple to use.
