[0019] When in use, after the connecting member 2 is connected to both ends of the first support platform 15 and the second support platform 18, and the first support platform 15 and the second support platform 18 are connected to the ground through the support column 14, the fixing block 5 is connected to the connecting block 3 through the connecting rod 4, and the connecting rod 4 is fixed by the latch 6;

[0020] The connecting member 2 is connected to the support rod 10 through an adjusting mechanism. The adjusting mechanism includes a motor 7, a worm 8, a worm gear 9, and a support rod 10. The interior of the connecting member 2 is fixedly connected to the motor 7, and the motor 7 is connected to the worm 8, and the worm 8 is meshed with the worm gear 9. The worm gear 9 is fixedly connected to the support rod 10, and the support rod 10 is connected to the steering rail 1. The bottom of the steering rail 1 is connected to the adjusting plate 11, and the lower part of the adjusting plate 11 is fixedly connected to the moving shaft 12.

[0021] When the steering rail 1 needs to be steered during use, the motor 7 drives the worm 8 to rotate.
