A chain 16 is sent along a guide 18 and hangs down up to the back side of the pipe. The chain 23 is turned with a driver 24 to get into contact with the pipe 11 and a hook 26 crosses the chain 16. Therefore, as the chain 16 is unwound, a connecting rod 25 is retained with a hook 26 to hold the pipe 11. The main body 12 is drown to the pipe 11 so that a roller 15 tightly contacts the pipe 11 to lock a sprocket 17.
