Abstract
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.
