When the first latching portion 21 and the second latching portion 31 are tripped, The groove 35 can accommodate the two second clamping members 12 so that the clamping member 3 is more stable and is less prone to shaking.

In this embodiment, the sleeve body 1 is provided with an internally threaded section 13 along one end of the axial direction, the abutment member 41 is provided with an externally threaded section 411, and the externally threaded section 411 is screwed on the internally threaded section 13. In detail, the sleeve body 1 is protrudingly provided with an operation portion 14 along the axial direction, the inside of the operation portion 14 communicates with the inside of the sleeve body 1, the internal thread section 13 is provided on the inner peripheral wall of the operation portion 14, The length of the pushing member 41 extending into the inside of the sleeve body 1 is controlled by screwing the pushing member 41. The outer peripheral wall of the operating part 14 is a polygonal column shape, which can be combined with a rotating tool (such as a wrench) to facilitate labor-saving operation.

In addition, preferably, the torque adjusting component 4 further includes a washer 43, the washer 43 is sandwiched between the elastic member 42 and the abutment member 41, and the washer 43 can abut the abutment member 41 The force of the shim 43 is evenly distributed to the elastic member 42 to avoid that the single point of the elastic member 42 is stressed too much and the deformation and compression amount after the stress is not long. In this embodiment, the elastic member 42 is a compression spring. The elastic member 42 is provided with a cutting plane 421 perpendicular to the axial direction at both ends along the axial direction, so as to smoothly spring against the spacer 43 and the card Between this piece.

In addition, one of the first locking portion 21 and the second locking portion 31 is provided with a plurality of circularly arranged concave holes 311, and the other is provided with at least one clamping bead 211, the at least one clamping bead 211 can be snapped against the concave holes 311, and in the present embodiment, the first locking portion 21 is provided with a plurality of the clamping beads 211, and the second locking portion 31 is provided with a plurality of the concave holes 311, When the driving member 2 receives a torque greater than the torque setting value, the clamping beads 211 jump out of the two concave holes 311, so that the driving member 2 can rotate relative to the sleeve body 1, in other embodiments The first latching portion 21 and the second latching portion 31 may also be a structure that the inclined surface is abutted or other tripped latching structures, which is not limited thereto.
