The connecting rod connection part is provided with meshing teeth for connecting the gear 7. The telescopic rod 12 is arranged on the middle gear 72, and the spring 13 is arranged between the telescopic rod 12 and the engine 5. One side of the telescopic rod 12 is also provided with a switch. When the telescopic rod 12 is pulled out, the middle gear 72 is driven to move to the right, and at this time, the connecting rod drives the lower gear 73 to cooperate with the groove 29 to make an upward movement.

[0030] Specifically, in order to enable the telescopic device to be self-started, a switch is arranged between the telescopic rod 12 and the water tank 9. The switch includes a support rod 16, the support rod 16 is provided with an iron block 14 on one side of the telescopic rod 12 and is connected with the water tank 9 on the other side. A support seat 15 connected with the vehicle body is arranged below the support rod 16. The switch is used to drive the telescopic device. When rainwater flows into the water tank 9, the weight of the water tank 9 increases, so that the iron block 14 is pulled out upward from the telescopic rod 12. When the water in the water tank 9 is pumped to a certain amount by the water pumping device, the switch will return to the initial position.

[0031] The groove 29 cooperates with the wheel of the vehicle body to drive the wheel 2 when the telescopic device operates.
