How to use chain pipe tongs and chain pipe tongs?

Chain pipe tongs and water pipe tongs are special tools for rotating circular members. Because the circular member has no shoulder armor, the rotation with chain tongs or water tongs is carried out by squeezing. When the chain pipe wrench is used, the chain is wound around the circular member, then hooked with the rod, and the rod is pressed in the opposite direction of the chain winding. At this time, the chain will grasp the circular member and rotate. If you rotate an angle clockwise, the lever will be pushed counterclockwise and then pressed clockwise. The pipe tongs are rotated by pressing the pipe with the front and rear dies. Generally, as long as the two molds basically press the pipe, the pipe can be rotated by pressing the handle, but the pipe will not be rotated if the direction is reversed. As long as you practice a few more times and realize the methods and skills of exertion, you will soon become proficient.
