Even if a pressing force is applied, And there is a risk of breakage of the fastening part, so that the locking and disassembling work is very difficult and the working time is also increased.

This prior art also supports a pipe using two semicircular semi-circular bands, one of which is fastened by a bolt and a nut, And the fastening portion is formed on one side by the pivot structure rotated by the hinge shaft. As described above, since the fastening quality such as the compression rate breakage rate is poor and the lock structure can not be easily disassembled, In addition, there is a problem in that it is difficult to use the tool because it is expensive and laborious due to the cost increase. Therefore, it is difficult to meet the general purpose requirement of the branch connection or the residual tool requiring productivity and cost reduction In the workplace where there is a shortage of labor, productivity and economy And the improvement of the sex has emerged as an urgent task.
