Since the wrench 36 needs to rotate around the axis when the wrench 36 is operated, if the connecting sleeve 20 and the wrench sleeve 30 rotate relatively, the circumferential force of the wrench 36 drives the connecting sleeve 20 and the wrench sleeve 30 to rotate relatively, and the force cannot be completely applied to the wrench 36, so that the connecting sleeve 20 and the wrench sleeve 30 are limited to rotate relatively by the cooperation of the limiting groove 31 and the limiting protrusion 21, thereby providing a force application point when the wrench 36 is operated, so as to facilitate the operation of the wrench 36.

The direction perpendicular to the first axial direction F1 is denoted as a first radial direction F2, the limiting groove 31 is formed on the inner wall of the trigger sleeve 30 along the first radial direction F2 in a recessed manner, and the limiting protrusion 21 is formed on the outer wall of the connecting sleeve 20 along the first radial direction F2 in an extending manner. The limiting groove 31 is located at one end of the pulling buckle sleeve 30 far away from the support tube 10, and the limiting protrusion 21 is located at one end of the connecting sleeve 20 far away from the support tube 10; in the first axial direction F1, the position of the limiting groove 31 corresponds to that of the limiting protrusion 21, so that the limiting protrusion 21 on the connecting sleeve 20 is sunk into the limiting groove 31 matched with the connecting sleeve, and the circumferential limiting of the connecting sleeve 20 and the wrench sleeve 30 is realized.

A positioning block 22 is further formed on an outer wall of the connecting sleeve 20, a positioning hole 11 matched with the positioning block 22 is formed on the supporting tube 10, and when the positioning block 22 is sunk into the positioning hole 11, the connecting sleeve 20 is limited to rotate around the first axial direction F1 relative to the supporting tube 10. The positioning block 22 is configured to be limited in one direction, and in the present embodiment, the positioning block 22 is a circular protrusion with an inclined surface. When the connecting sleeve 20 is in splicing fit with the supporting tube 10 along the first axial direction F1, the inclined surface of the positioning block 22 is in sliding contact with the inner wall of the supporting tube 10 until the positioning block 22 sinks into the positioning hole 11, thereby completing the connection between the connecting sleeve 20 and the supporting tube 10; when the connecting sleeve 20 is separated from the supporting tube 10, the inclined surface of the positioning block 22 is squeezed into the gap of the positioning hole 11 and is separated along the inner wall of the supporting tube 10, so that the connecting sleeve 20 is separated from the supporting tube 10.

Wherein, still be formed with guide way 23 on the adapter sleeve 20, guide way 23 is followed first radial F2 runs through adapter sleeve 20, the inner wall of stay tube 10 be formed with guide bar 12 of guide way 23 looks sliding fit, guide bar 12 certainly the inner wall of stay tube 10 is followed first radial F2 extends and forms, through the guide effect of guide bar 12 fish guide way 23 to in order to realize spacing groove 31 and spacing protruding 21's cooperation, and realize the cooperation of locating piece 22 and locating hole 11.

A first limit step 24 is further formed on the connecting sleeve 20, and a second limit step 32 matched with the first limit step 24 is further formed on the pulling buckle sleeve 30. The first limiting step 24 is formed by extending outwards from the outer wall of the connecting sleeve 20 along the first radial direction F2, and the second limiting step 32 is formed by sinking from the inner wall of the trigger sleeve 30 along the first radial direction F2; when the connecting sleeve 20 is inserted into the pulling buckle sleeve 30 from the end of the pulling buckle sleeve 30 away from the support tube 10 along the first axial direction F1, the first limiting step 24 abuts against the second limiting step 32 to limit the movement of the connecting sleeve 20 along the first axial direction F1 and toward the support tube 10.

In this embodiment, the trigger sleeve 30 includes: a sleeve part 33, an ear part 34, a pull rod 35 and a trigger 36.
