[0033] The power mechanism 2 is used to provide rotational power. The output end of the power mechanism 2 is connected to the transmission shaft 3. The transmission shaft 3 is provided with a torque meter 4. The torque meter 4 is used to monitor the torque size when the transmission shaft 3 rotates.

[0034] A first chuck 5 is provided at the end of the transmission shaft 3, and the first chuck 5 is used to fix the steel sleeve; in this embodiment, the power mechanism 2 is a motor, which drives the transmission shaft 3 to rotate; in other embodiments, the power mechanism 2 can also be a fuel engine.

[0035] The base, the power mechanism 2 is arranged on the base; the bracket 13 assembly, the bracket 13 assembly includes an adjusting rod 12 and a bracket 13, one end of the adjusting rod 12 is fixed to the base, and the other end of the adjusting rod 12 is fixedly connected to the bracket 13, and a positioning hole is provided on the bracket 13, the positioning hole is coaxially arranged with the chuck, and the steel bar passes through the positioning hole and is fixed in the positioning hole. In this embodiment, a screw is tightened around the periphery of the positioning hole on the bracket 13. When the steel bar passes through the positioning hole, the screw is screwed so that the screw presses against the steel bar to achieve the steel bar being fixed in the positioning hole; alternatively, a hydraulic rod 16 is arranged around the periphery of the positioning hole on the bracket 13, and a pressure block is provided at the end of the hydraulic rod 16; when the steel bar passes through the positioning hole, the hydraulic rod 16 is controlled to extend so that the pressure block at the end of the hydraulic rod 16 presses against the steel bar, and the pressure block can increase the contact area with the steel bar, so that the steel bar is more firmly fixed in the positioning hole.

[0036] In this driving device, the steel sleeve is fixed on the chuck, the steel bar is fixed in the positioning hole of the bracket 13, and the threaded end of the steel bar is aligned with the steel sleeve. The power mechanism 2 then drives the steel sleeve to rotate, thereby fixing the steel bar at one end of the steel sleeve. During this process, the value of the torque meter 4 is observed in real time. When the torque meter 4 displays a value within the tightening value range, the power mechanism 2 can be shut down. The torque value of the connection between the steel bar and the steel sleeve is monitored in real time by the torque meter 4 to ensure that the steel bar and the steel sleeve can achieve optimal docking stability.

[0037] A positioning seat 6 is further provided on one side of the base, and a transmission cylinder 8 is rotatably provided in the positioning seat 6.

[0049] In one embodiment of the present application, the output shaft of the hydraulic rod 16 is lifted upward, thereby lifting the other end of the base, thereby causing the base to rotate about the hinge end, so that the base can be tilted and raised to a certain angle. In this embodiment, the end of the hydraulic rod 16 is provided with a guide wheel 17, which directly contacts the base.

[0050] A connecting rod assembly 7 is provided between the support plate 1 and the base. The connecting rod assembly 7 includes two connecting rods.
