A chain replacement apparatus includes a body seat, an operation assembly, and a repair block. The operation assembly is rotatably disposed on the body seat. The repair block is disposed on the body seat and selectively switched among a removing status, a combining status, and a riveting status, so as to, through the operation assembly, break the chain, press the outer and inner chain plates, and rivet the chain. The repair block rotates about an action axis to be switched among different statuses, facilitating an efficient chain maintenance and replacement operation.

A wedge driver and method therefor is presented. A wedge driver can be operably coupled to different ends of a link joiner to drive a wedge therebetween to form a single link. The wedge driver can also drive the wedge out of the link joiner. The present disclosure provides the benefit of allowing the safe and effective removal of the link joiner by preventing violent or forceful decoupling of a link joiner. The wedge driver can include a trunk, a first prong, a second prong, a bolt, and a driver. The driver can be spring enabled, such that the driver can recede into the trunk as the bolt egresses the trunk. A bolt of the wedge driver can push a driver out of the trunk to axially drive the wedge into (or out of) a link joiner without rotating the wedge.

A chain tool includes a body having a driving hole, a stop portion, and a receiving portion located between the driving hole and the stop portion in an axial direction. A pressing member is received in the receiving portion and is movable relative to the body in the axial direction. A push member is in threading connection with the first threaded portion and is movable relative to the body between a first position distant to the stop portion and a second position adjacent to the stop portion. The pressing member is pressed by the push member and moves in an arcuate path when the push member moves between the first and second positions.
