Claims

[Scope of utility model registration request]

It comprises a ratchet handle, a cylindrical joint box whose base end is detachably connected to the ratchet handle, and a cylindrical socket box provided at the distal end of the joint box. In the torque wrench, the socket box includes a cartridge that is slidably disposed so as to hit the driven member, and a cartridge that is placed on the side opposite to the engaging part. The joint box is provided with a joint rod that is slidably disposed so as to bias the cartridge toward the engaging portion, and the ratchet handle is provided with a return spring that biases the cartridge toward the engaging portion. a drive rod slidably arranged to urge the cartridge toward the cartridge;
and a drive mechanism that drives the drive rod toward the joint rod upon completion of fastening of the driven member, and the cartridge has a sphere that applies paint or the like to the driven member when the driven member is knocked. A torque wrench with a marking mechanism.
