Claims

[Scope of utility model registration request]

A cylindrical casing 12 consisting of a lever 1, a torque adjustment device 11, and a wrench head 43, the torque adjustment device 11 being attached to the tip of the lever 1, and a holding shaft 14 passing through the casing 12 concentrically therewith. , has a plurality of longitudinal grooves 18 extending in the axial direction on the outer circumference at intervals in the circumferential direction, and a grooved ring 17 fixed concentrically to the holding shaft 14 and a tapered portion 25 provided on the outer circumference. A plurality of horizontal holes 24 correspond to the vertical grooves 18 of the attached ring 17.
an annular ball holder 21 which penetrates in the radial direction and is fixed within the casing 12; a ball 29 accommodated in the vertical groove 18 so as to face the horizontal hole 24 of the ball holder 21; and a taper of the ball holder 21. An annular spring seat 31 having a tapered part 33 facing the part 25 on the inner periphery and inserted into the casing 12 so as to be freely displaceable in the holding axis direction, and the spring seat 31 facing the ball holder 21. A wrench with a torque adjustment function, characterized in that the wrench head 43 is attached to a holding shaft 14.
