The two first slide rails 401 are fixedly connected to the vehicle body bracket in parallel. Inside the two first slide rails 401, a first long lead screw is rotatably connected along the X direction respectively. A first steering gear (bevel gear) is threadedly connected to the first long lead screw. The first steering gear meshes with a second steering gear on a second synchronizing rod 407 driven by the first driving motor 403. The meshing of the first steering gear and the second steering gear can achieve power transmission in the vertical direction.

The lead screw nut at the bottom of the first slider 402 is rotatably connected to the first long lead screw. The rotating first long lead screw drives the first slider 402 to slide back and forth on the first slide rails 401.
[0026] Refer to Figure 3 , this embodiment further includes a first locking motor 406. The first locking motor 406 is used to control the locking of the first slide rail 401 and the first slider 402. Only after the first locking motor 406 is unlocked can the first driving motor 403 drive the first slider 402 to slide on the first slide rail 401. Two paddles are arranged on a first synchronizing rod 404 driven by the first locking motor 406. Locking seats are arranged on the two first sliders 402.
