Claims

[Scope of utility model registration request]

The clutch has a main drive shaft with a die attached to its front end and a plurality of protruding pawls on the side surface of the other end, a weed removal body installed in the drive shaft, a corresponding pawl on one end, and a plurality of protruding pawls on the other end. A driven shaft of the clutch that forms the sliding key, a compression spring connected to the driven shaft, a tool body that accommodates both shafts to adjust the degree of engagement of the claws, and a female threaded part of the tool body. A driven body having a vertical hole in which the threaded portion is screwed together and the driven shaft associated with the machining capacity scale of the tool H disposed on the outer periphery can slide; and a main body fixed to the outer periphery of the tool body. A cover, a cap collar provided at the tip of the drive shaft to supplement rotation, and a pusher that is loaded into the cap collar and has a normal thread at the front and a reverse thread at the rear, with a lock nut fitted into the thread. A screw, a socket body that is fixed to the driven body and has a male thread on the front end and a through hole on the outer periphery of the other end, and a screw that is screwed together with the female thread on the male thread of the socket body to adjust the scale. It is equipped with a fixing ring for fixing the mechanism, a vertical hole in the hollow part, a shank at the other end, a shank body inscribed in the socket body, and a connecting pin for connecting the socket body and the shank body to the driven body. The shank body is located inside the socket body, and after the die bites into the workpiece under normal rotation, the tool body is pulled out from the shank body by stopping the shank body, compressing the transmission of machining capacity from the main drive shaft. A thread cutting tool characterized in that a force is applied to the driven shaft via a spring, causing the main driving shaft to idle when the machining capacity is exceeded.
