The bottom of the fixing rod 24 is slidably connected in the inner cylinder 25, and the top of the fixing rod 24 passes through the inner cylinder 25. When the connecting cover 11 moves upward, the fixing rod 24 moves upward in the inner cylinder 25. When the fixing rod 24 cannot move, the inner cylinder 25 moves in the outer cylinder 26 to ensure the upward movement of the connecting cover 11. When the carriage 2 needs to be folded and stored, first connect the connecting female part 4 to the connecting male part 3 on the mounting rod 8, and make The hydraulic telescopic rod 5 drives the supporting leg 6 to move downward, and then the car 2 is lowered by the crane. When lowering, the mounting plate 14 is driven upward by the lifting device to move away from the groove 10 until the positioning block 16 is inserted into the positioning groove of the supporting leg 6. At this time, the shock-absorbing pad 15 is squeezed for shock absorption, and the shock-absorbing spring 13 can further play a shock-absorbing effect. After positioning, the lifting device drives the mounting plate 14 to reset downward, so that the supporting leg 6 can be slowly placed on the car 2 below, thereby avoiding excessive impact force between the upper car 2 and the lower car 2. After placing, the mounting rod 8 can be assembled together. The bottom of the car 2 is supported on the lower car 2 by the supporting leg 6, and the left end is fixed by connecting the female part 4 and the connecting male part 3, and the positioning magnet 17 adsorbs and fixes the supporting leg 6, thereby improving the stability of the car 2 when it is folded and stored.
