Claims

[Claim for Utility Model Registration] When the screw tightening torque reaches a certain level, the clutch part moves in the opposite direction to the biasing direction of the spring to cut off the power from the motor, and the inner diameter part of the tip of the clutch housing has an axial direction. A sleeve is movably fitted to the adjuster string and connected to one end of the adjuster string and the spring at the other end, and when the adjuster string is turned by hand, the sleeve is moved in the axial direction, and the sleeve is moved between the springs. The slip torque of the clutch is adjusted by adjusting the force, and the adjuster string is adjusted by positioning a protrusion provided on an elastic body such as a leaf spring in a groove provided on the outer diameter of the clutch housing. In a screwdriver for torque adjustment that prevents positional movement, rotation is prevented by bent portions provided at both ends of the annular spring, and displacement in the axial direction is prevented by an annular spring storage groove provided in the adjustment spring. A torque adjustment mechanism characterized in that the annular spring is attached to the adjuster string.
