Problems solved by technology

[0003] However, when the locking lever of the self-locking slide buckle is pulled and unlocked by the handle, the rotating projection of the locking lever needs to move a certain distance in the receiving groove to engage with the tongue, which increases the operator's ability to use the handle. The distance required to lift the locking hook reduces ease of operation
In addition, when assembling the self-locking slide buckle, it is necessary to first set the rotating lug of the locking lever in the receiving groove, and then punch out the tongue and tenon through a mold, which requires high assembly precision and is not conducive to automation to assemble

Description

technical field [0001] The invention relates to an invisible slider, in particular to a self-locking invisible slider. Background technique [0002] At present, there are many kinds of invisible sliders. These invisible sliders allow the elements of the zipper to be concentrated on one side of the strap when the zipper is closed, leaving no elements on the other side of the strap, thereby hiding the elements of the zipper. The invisible slider is a relatively special product, and its uniqueness determines that it has less space for installing the hook and spring, and at the same time, it is more difficult to realize automatic assembly. For example, the Chinese invention patent disclosed on February 4, 1998 with the application number 97114771.X discloses a self-locking slider with an invisible slider. The upper plate of the sliding button body is provided with a concave rotating projection receiving groove, and the receiving groove extends into a fastener guide post. A lo...
