| 20090255229 | Chain disconnecting and connecting tool - There is provided a highly durable and compact chain disconnecting and connecting tool that may be used for a chain at a sprocket part for winding the chain and that can receive an operational load at two places. A first block has a pressure actuating member screwed therewith and a coupling member fixed thereto. A second block is coupled with the first block turnably by the coupling member and has a closed-end hole on one side and a through hole on another side of the block. The tool is attached to the chain from an opening while positioned and engaging an edge projection of a tap bolt that is screwed with the first block with the closed-end hole or the through hole. | 10-15-2009 |
