Abstract (en)
A puller includes a collar, claws, a synchronizer and a threaded rod. The collar includes a space, a screw hole in communication with the space, slots in communication with the space, and pivotal connectors located corresponding to the slots. The claws are pivotally connected to the pivotal connectors. Each of the claws includes a protuberance movable in and along a corresponding one of the slots. The synchronizer includes a receiving portion for receiving the protuberances. The synchronizer is movable in the collar between an opening position and a closing position. In the opening position, the synchronizer opens the claws by the protuberances. In the closing position, the synchronizer closes the claws by the protuberances. The threaded rod is inserted in the screw hole of the collar.
