[0007] Preferably, the material of the wrench bushing is nylon material.

[0008] Preferably, the torsion mechanism includes ring seat, and the ring seat is installed with handheld rod.

[0009] Preferably, the center of the handheld rod is installed with motor, and the output end of the motor is installed with rotating rod.

[0010] Preferably, the both ends of the rotating rod are installed with rotating block, and the inside of one rotating block is installed with mounting block.

[0011] Preferably, the mounting block is equipped with connector slot, and connector post is installed in connector slot.

[0012] Preferably, the ring seat and wrench bushing share the same center.

[0013] The utility model discloses a beneficial effect is: wrench main part uses high strength steel to make, guarantee not to deform in the use process to realize the torque lossless, in the use process, wrench bushing and aluminum alloy part contact, avoid the tool to the part surface cause the indentation, and can reach the part design installation torque.

[0014] The torsion mechanism occupies small space, and the rotation of the wrench main body is realized through the torsion mechanism, so that the wrench is convenient to use in narrow space. BRIEF DESCRIPTION OF DRAWINGS
