Therefore, one end of the elastic member 22 is inserted into the receiving groove 31 and abuts against the abutting member 3, and the length of the receiving groove 31 is The torsion sleeve can be shortened in length without changing the length of the elastic member 22, so that the torsion sleeve can shorten the overall length of the torsion sleeve under the same torque specification, thereby improving the working environment in a narrow environment. The working efficiency inside is easy to store.

Preferably, the outer wall of the body 1 and the outer wall of the sleeve 5 are provided with a circumferentially arranged scale 12, and the other is provided with an indicator portion 51 corresponding to the scale portion 12, In the embodiment, the outer wall of the body 1 is provided with the scale portion 12, and the outer wall of the sleeve 5 is provided with the indicator portion 51 and has an arrow shape, and the index portion 51 and the scale portion 12 are displayed on the torque sleeve. The torque setting value, when the kit 5 is rotated, the change of the scale corresponding to the index portion 51 can also be viewed, and the scale portion 12 and the index portion 51 need only be processed on the outer wall of the body 1 and the outer wall of the sleeve 5. Therefore, the manufacturing cost is low.

Specifically, the body 1 is further disposed with a first insertion hole 13 in the radial direction. The abutting member 3 defines a sliding slot 33 along the axial direction 11 . A first pin member 14 is inserted into the sliding slot 33 and the first portion A jack 13 can slide only against the body 1 without rotating.

The abutting member 3 further includes a ring wall 34 and a bottom wall 35. The ring wall 34 defines the receiving groove 31. The bottom wall 35 is connected to the ring wall 34 away from the end of the driving portion 2. The ring wall 34 has an opening 36 near one end of the driving portion 2, and the elastic member 22 abuts against the bottom wall 35. The sliding slot 33 is opened on the ring wall 34 and extends to the opening 36 for easier processing. The chute 33 is formed.

Further, the mandrel 4 is provided with a non-circular section 42 away from one end of the threaded section 41. The sleeve 5 is provided along the axial direction 11 with a pair of perforations 52 which should be in the shape of a non-circular section 42. 42 is slidably inserted into the perforation 52, and the mandrel 4 cannot be rotated relative to the sleeve 5. In addition, the sleeve 5 is connected to one end of the driving portion 2 away from the end of the driving portion 2 to be connected with a first step 53 of a larger diameter. A locking member 15 is locked in the non-circular portion 42 along the axial direction 11 and blocked. The first step portion 53 is limited to prevent the knob from coming off the mandrel 4.

The kit 5 is movable relative to the spindle 4 in the axial direction 11 in a locking position and a release position. The body 1 is provided with a first card portion 16 along the axial direction 11 , and the sleeve 5 is provided along the axial direction 11 . a second card portion 54; wherein, when the kit 5 is in the locked position, the first card portion 16 is engaged with the second card portion 54, and the kit 5 cannot be rotated relative to the body 1; when the kit 5 is When the first card portion 16 is not engaged with the second card portion 54, the kit 5 is rotatable relative to the body 1 to adjust the torque setting value.

In detail, the main body 1 is further provided with a fixing block 17 , and the fixing block 17 is disposed at one end of the sleeve 5 with the first card portion 16 , and the body 1 is further provided with a second insertion hole 18 , The second pin member 19 is inserted into the second insertion hole 18 and the fixing block 17 , so that the first card portion 16 is not integrally formed in the body 1 , and the first card portion 16 is only required to be additionally installed. The fixing block 17 and the second pin member 19 of the card portion 16 can reduce the manufacturing cost of the body 1.

In the present embodiment, the mandrel 4 is further provided with a flange 43 which is located between the threaded section 41 and the non-circular section 42 . The flange 43 abuts against the fixing block 17 toward the One end of the driving portion 2 blocks the spindle 4 and prevents the spindle 4 from moving away from the driving portion 2 to be separated from the body 1.
