When the height sensor 406 is in a suitable position, the spring 404 resets and pushes the bayonet 405 into the interior of the bayonet groove 407, thereby fixing the height sensor 406 in the fixing plate 401, thereby completing the installation of the height sensor 406. When the tread 17 is transmitted by the first linkage rod 6 and the second linkage rod 11, the first drive motor 702 is started, and the first drive motor 702 drives the threaded rod 703 to rotate, so that the connecting block 706 can slide through the slider 705, and the bottom of the connecting block 706 is fixed. The slider 705 plays a limiting role when sliding in the slide groove 701, so that the connecting block 706 will not rotate and will not shake when sliding.
