US Patent 11572026 Fastener

A fastener includes a fastening pin and a sleeve component disposed around the fastening pin and movable up and down relative to the fastening pin. The sleeve component includes fixing claws that are able to stretch outward and retract inward. A pin of the fastening pin comprises a small-diameter rod section and an upper large-diameter rod section. When the fixing claws move relative to the pin to abut against an outer surface of the upper large-diameter rod section, the fixing claws stretch outward, and the fastener is in a locked state. When the fixing claws move to the outside of the small-diameter rod section relative to the pin, the fixing claws retract inward, and the fastener is in a release state.
