The invention discloses a gear type traceless
pipe wrench and a method. The traceless
pipe wrench comprises a jaw and a
wrench handle, wherein the jaw comprises an upper jaw
assembly and a lower jaw
assembly, and the wrench
handle comprises a rocking
handle assembly; one end of the upper jaw assembly is hinged to the rocking handle assembly, the other end of the upper jaw assembly is hinged to thelower jaw assembly, and a large gear is fixedly arranged at the other end of the lower jaw assembly; a small gear is arranged at the hinged position of the upper jaw assembly and the rocking handle assembly; a return
ratchet wheel is arranged on the right side of the small gear; and the upper jaw assembly and the lower jaw assembly each comprise a clamping part, and a rubber pad is arranged on the inner side wall of each clamping part. The working method of the traceless
pipe wrench completes the construction of a pipe through a plurality of steps. According to the traceless
pipe wrench, thegear combination is arranged, so that the holding force of the traceless
pipe wrench is large in the construction process, and the slipping probability is small; the rubber pads are arranged, so thatthe surface of the pipe is effectively protected; and the return
ratchet wheel is arranged, so that the jaw of the traceless
pipe wrench can loosen the pipe when the traceless pipe wrench returns, thetraceless pipe wrench does not break away from the pipe, the force can be quickly applied when the pipe is screwed, and time and labor are saved.
