[0024] See also Figure 3 The auxiliary structure includes: four sliders 9, an auxiliary fixing frame 10, two generators 11, an auxiliary roller 12, a plurality of telescopic sleeves 13 and a plurality of telescopic rods 14; the four sliders 9 are respectively mounted on the inner wall surfaces of the two rear guide grooves 4, the auxiliary fixing frame 10 is mounted on the inner wall surfaces of the four sliders 9, the two generators 11 are respectively connected to the auxiliary fixing frames 10, the auxiliary roller 12 is mounted on the inner wall surfaces of the two generators 11, the plurality of telescopic sleeves 13 are respectively mounted on the rear wall surfaces of the auxiliary fixing frames 10, and the plurality of telescopic rods 14 are respectively mounted on the inner wall surfaces of the plurality of telescopic sleeves 13.

In this embodiment, the plurality of compression springs 23 are contracted, and the auxiliary roller 12 supports the rear wheel of the electric vehicle through elastic force, thereby limiting the position of the rear wheel of the electric vehicle.

[0026] See also Figure 4 Two anti-skid sleeves 22 are installed on the lower wall of the fixed base 1. In this embodiment, the two anti-skid sleeves 22 increase the friction between the fixed base 1 and the ground.

[0027] See also Figure 4 Four guide screws 20 are installed on the lower wall of the fixed base 1, and the outer walls of the four guide screws 20 are respectively covered with load-bearing screw sleeves 21.

[0028] In this embodiment, when the rear wheel of the electric vehicle is pressed on the fixed roller 5, the auxiliary roller 12 drives the auxiliary fixing frame 10 to move backward according to the size of the rear wheel of the electric vehicle, and the auxiliary fixing frame 10 drives the plurality of telescopic sleeves 13 to shrink along the plurality of telescopic rods 14 respectively, and drives the plurality of compression springs 23 to shrink.
