Abstract

The utility model discloses a clasp reset structure in a self-touch lock impact mechanism. The clasp reset structure in the self-touch lock impact mechanism can not produce the phenomenon that the clasp can not reset when a door and a door frame produce displacement, and a main lock tongue stretches out and an inclined lock tongue does not completely stretch in place. The clasp reset structure in the self-touch lock impact mechanism comprises a main lock tongue torsion spring, a retreat-stopping slice, a dragging plate, a rotating slice, a clasp and a clasp torsion spring. A pillar I is arranged at the top end on the head portion of the rotating slice, a groove is arranged in the head portion of the rotating slice, a pillar II is arranged at the bottom of the inner wall of a groove hole of groove on the head portion of the rotating slice, a rotating slice sliding groove and a poking slice are arranged on the tail portion of the rotating slice, the rotating slice and the clasp are arranged on a retreat-stopping slice pillar II in a rotatable mode sequentially, the poking slice on the rotating slice is matched with a tail hook on the tail portion of the inclined lock tongue of the self-touch lock, the side face of the rotating slice is tightly attached to the hook of the clasp, the pillar I and the pillar II on the rotating slice are inserted into a sliding groove II on the retreat-stopping slice, and the hook on the clasp tends to be matched with a hook pillar on the dragging plate due to the fact that the clasp is under the action of the clasp torsion spring.
