Anti-pinch device

Abstract

An anti-pinch device includes a first body and a second body, the first body is fitted to an inner surface of a movable part to be protected (e.g., an inner surface of a drawer) via a fixing surface, and the second body is limited and retained in a first position to abut against the body to be protected (e.g., a cabinet body) via an abutting surface; and when the second body is displaced to a second position, the abutting between the second body and the body to be protected is released, allowing the movable part to be protected to be displaced and closed.
