Claims

[Scope of utility model registration request]

The hollow handle has a swingable inner handle,
A ratchet handle for a torque wrench is equipped with a tightening torque setting mechanism that disengages from the upper handle when a force exceeding a set torque is applied. It is equipped with a ratchet mechanism that transmits torque in only one direction to the drive cylinder from the head, and has first and second drive corners of different sizes on both sides of the polygonal main body for socket engagement. A drive unit is formed by integrally forming the polygonal main body, and the polygonal main body engages with the inner surface of the drive cylinder so that it can be freely inserted into and removed from the drive cylinder and can be moved in the axial direction, and one drive corner protrudes from the drive cylinder and the other is inside the drive cylinder. A ratchet handle for a torque wrench that is equipped with a locking mechanism that locks the drive unit in a state where it fits into the wrench.
