Puller

Abstract

A puller includes a collar (10), claws (20), a synchronizer (30) and an abutting element (40). The collar (10) includes slots (18) and pivotal connectors (15) located corresponding to the slots (18). The claws (20) are pivotally connected to the pivotal connectors (15). Each of the claws (20) includes a protuberance (25) movable in and along a corresponding one of the slots (18). The synchronizer (30) includes a receiving portion (32) for receiving the protuberances (25). The synchronizer (30) is movable in the collar (10) between an opening position and a closing position. In the opening position, the synchronizer (30) opens the claws (20) by the protuberances (25). In the closing position, the synchronizer (30) closes the claws (20) by the protuberances (25). The abutting element (40) is extensible from the collar (10).
