The rear foot assembly 300 includes a rear foot 310 and a rear lift mechanism 320 for driving the lifting movement of the rear foot 310. As shown in fig. 5, the link assembly 400 includes at least two links and a stopper 430 connecting adjacent links. The present embodiment preferably has two links, i.e., a front link 410 and a rear link 420, the front link 410 being connected to the front lifting mechanism 220, and the rear link 420 being connected to the rear lifting mechanism 320. The two links are detachably connected by a stopper 430.
The stopper 430 has a locked position and an unlocked position. When the stopper 430 is located at the locking position, the front lifting mechanism 220 is in driving connection with the rear lifting mechanism 320 through the connecting rod assembly 400, for example, when the front lifting mechanism 220 is adjusted and the height of the front foot 210 is adjusted, the rear lifting mechanism 320 is linked with the front lifting mechanism, so that the height of the rear foot 310 can be synchronously adjusted; or adjust the rear lifting mechanism 320 to drive the front lifting mechanism 220. When the stopper 430 is located at the unlocking position, the two connecting rods are separated, the front lifting mechanism 220 can be in driving connection with the rear lifting mechanism 320, and at the moment, the front lifting mechanism 220 and the rear lifting mechanism 320 can be independently adjusted respectively, so that the heights of the front foot 210 and the rear foot 310 can be adjusted respectively.
The height adjusting device is characterized in that the connecting rod assembly 400 is connected between the front bottom foot and the rear bottom foot, and the front bottom foot 210 and the rear bottom foot 310 can be lifted and lowered freely when the ground is uneven through the locking and unlocking operations of the stop piece 430; synchronous lifting of the front bottom foot 210 and the rear bottom foot 310 can be achieved when the ground is level, efficiency is improved, and uniformity of lifting height is guaranteed.
As shown in fig. 4 and 5, the front lifting mechanism 220 and the rear lifting mechanism 320 have the same structure and respectively include a housing 221, a worm wheel 222, and a worm 223.
