[0006] A steering shaft is rotatably connected in the steering column. Both ends of the steering shaft extend out of the steering column, and one end is connected to the steering wheel, and the other end is connected to the intermediate shaft through a universal joint. The intermediate shaft is connected to the main shaft of the electric power steering machine through the universal joint, and the main shaft of the electric power steering machine is connected to the steering machine.

[0007] Furthermore, two connecting plates are provided on the mounting plate, the two connecting plates are respectively located on both sides of the adjusting bracket, and the adjusting bracket is hinged to the connecting plates.

[0008] Furthermore, an arc-shaped limiting groove is provided on the connecting plate, and a limiting bolt is provided between the adjusting bracket and the arc-shaped limiting groove, and two ends of the limiting bolt pass through the two arc-shaped limiting grooves respectively.

[0009] Furthermore, a locking head is provided at the end of the piston rod of the self-locking gas spring, a handle is hinged on the locking head, a push rod slides inside the piston rod, the end of the handle contacts the push rod, and the sliding of the push rod can open or close the passage between the two air chambers in the cylinder of the self-locking gas spring, and the locking head is hinged to the steering column.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: when adjusting the angle of the steering column, the handle on the lock head is loosened, and the loosened handle is separated from the push rod, so that the passage between the two air chambers in the self-locking gas spring cylinder is opened. At this time, the steering column can be rotated, and after adjusting to a certain angle, the handle is closed again to press the push rod, and the passage between the two air chambers in the cylinder is re-closed, thereby locking the piston rod of the self-locking gas spring and fixing the steering column angle without requiring additional installation space, thereby reducing the frame volume; the electric power steering is used to provide power assistance for the vehicle's steering, reducing the force required by the driver when steering, so that the vehicle can be steered more easily.
