Patent ID: 7721520

Claim:
A chain disconnecting and connecting tool for disconnecting a chain by removing a pin out of the chain and for connecting the chain by deforming a pin of a chain linking member with a remainder thereof, comprising: a first block; a pressure actuating member engaged with the first block; a second block having a cutout into which a head of the pin of the chain linking member may be fitted and a through hole through which the pin of the chain may be inserted, and disposed selectively with respect to the pressure actuating member so that the cutout or through hole thereof aligns with the pressure actuating member, the pressure actuating member being laterally moveable between the first and second blocks for contacting the chain pin of the chain during disconnection or connection thereof; a coupling member for coupling the first and second blocks, and for supporting a tensile force acting thereon during disconnection or connection of the chain; a tap member, disposed on an opposite side of the pressure actuating member with respect to the coupling member, for supporting a compressive force acting thereon during disconnection or connection of the chain, the tool being attachable to the chain from an opening of the tool at an opposite side of the tap member with respect to the coupling member; and a grip engaged with the first block for enabling a user to grasp the tool during use thereof.
