[0039] To further optimize the solution, a tightening mechanism 4 is further provided between the head frame 31 and the tail frame 32. In the wrapped state, the tightening mechanism 4 tightens the head frame 31, the tail frame 32 and the middle frames 33. In the unfolded state, the tightening mechanism 4 loosens the head frame 31, the tail frame 32 and the middle frames 33 and unfolds the head frame 31, the tail frame 32 and the middle frames 33 into a slope and connects to the ground.

When locking, the first lock buckle 51 can be directly aligned with the second lock buckle 52 and pushed hard, so that the first lock buckle 51 is directly aligned with the second lock buckle 52 to lock. This is the existing technology and will not be elaborated on here.

[0045] To further optimize the solution, the telescopic plate 6 also includes: a first extending plate 61, which is fixed to the side of the first frame 31 close to the vehicle body; a movable plate 63, which is sleeved on the fixed component 7, and a plurality of movable rods 64 are provided on the side of the movable plate 63 close to the fixed component 7, and the movable plate 63 slides on the fixed component 7 through the plurality of movable rods 64; two second extending plates 62 are provided, which are fixed on the side of the movable plate 63 close to the ground.

[0046] According to a further optimization scheme, the fixing assembly 7 includes: a fixing flange 72, fixed to the vehicle body by a plurality of connecting bolts 74; a fixing cavity 71, fixed to the side of the fixing flange 72 away from the vehicle body, the fixing cavity 71 is provided with sliding grooves 73, the number of which is the same as and adapted to the movable rod 64, and the movable rod 64 is slidably connected in the sliding grooves 73; a fixing threaded hole 75, opened on the side of the fixing cavity 71 away from the vehicle body, a plurality of fixing bolts 2 are arranged on the spare tire 1, the number of the fixing threaded holes 75 is equal to and adapted to the fixing bolts 2, and in the wrapped state, the spare tire 1 is threadedly connected by the plurality of fixing bolts 2 and the plurality of fixing threaded holes 75.
