[0025] For ease of installation, the shock absorbing member 8 may be installed in the opposite direction, i.e., the movable end is provided on the main frame 1 and the fixed end is provided on the sub-connecting member 7 or the main connecting member 4, with the fixed end preferably being provided below the installation position of the movable end.

[0026] A number of third pivot points 12 are provided on the main connecting member 4, at least two of the third pivot points 12 are provided, the third pivot points 12 are through-hole bodies, a number of support shafts are provided on the through-hole bodies, a first connecting rod 11 is provided on the support shaft and rotatably fitted thereto, and a rotation hole is preferably provided in the central part of the first connecting rod 11, that is, the first connecting rod 11 is rotatably provided on the third pivot points 12, that is, at least two sets of the first connecting rods 11 are provided.

When the main connecting member 4 moves vertically, since it is connected to the main frame 1 via the sub-connecting member 7, the main connecting member 4 jumps parallel to the main frame 1 only around the first pivot point 5, so that the main frame 1 will not be tilted by the obstacle on one side of the left wheel 2 or the right wheel 3. At the same time, when the main connecting member 4 jumps, it receives the shock absorbing force from the shock absorbing member 8, so that even if the wheel encounters an obstacle, it can absorb the shock and quickly stabilize it, improving the stability of the wheel and preventing the main frame 1 from overturning due to the obstacle.
