[0009] The moving rod is arranged on the surface of the clamping plate.

[0010] Preferably, the clamping plates are provided in two groups, a steering rod is placed between the two groups of clamping plates, the movable plate is inserted in the slide groove, and the movable plate can move in the slide groove.

[0011] Preferably, one end of the spring is connected to the surface of the movable plate, and the other end is connected to the inner wall of the slide groove. A connecting rod is fixed to the surface of the movable plate, and the connecting rod is fixed to the surface of the clamping plate.

[0012] Preferably, a sleeve tube is provided at the end of the connecting rod, a top holding ring is fixed to the end of the sleeve tube, the sleeve tube can move on the surface of the connecting rod, and the connecting rod can be inserted into the interior of the sleeve tube.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The sleeve tube proposed in the utility model drives the clamping plate to move and then clamps it on the surface of the steering tie rod. The moving plate on the surface of the clamping plate is pressed against the surface of the steering tie rod. Under normal circumstances, the spring inside the extension rod pulls the plug rod so that the first half ring is pressed against the surface of the second half ring, so that the moving rod and the moving plate are subjected to force.
