At the same time, the rotating arm 5 can move on the outside of the first fixed shaft 4, thereby further adjusting the position of the torque gun. The torque gun can be adjusted by rotating the switch handle 21, so that the rotating connecting rod 29 rotates on the Z-axis rotating sleeve 16, so that the Z-axis rotation direction of the torque gun can be adjusted. At the same time, the switch handle 21 is rotated through the X-axis, and the switch handle 21 can drive the X-axis rotation direction of the torque gun to be adjusted, thereby completing the all-round adjustment of the torque gun. In this process, the first air-controlled brake 7 and the second air-controlled brake 11 can be controlled by the switch group to lock the positions of the first brake disc 6 and the second brake disc 10 respectively, thereby completing the fixing of the positions of the rotating arm 5 and the long swing arm 13.
