[0024] The lower surface of the handrail 7 is fixedly connected with a steering rod 8, and the operator controls the steering of the sandbox body 1 by holding the handrail 7, which provides a force point for the operator. The lower end of the steering rod 8 is rotatably connected to the inner hole of the upper surface of the mounting plate 16. The outer surface of the steering rod 8 is fixedly connected with a half gear 9. The handrail 7 is fixedly connected with the steering rod 8. When the operator rotates the handrail 7, the steering rod 8 rotates, and then drives the half gear 9 to rotate. The half gear 9 is meshed with a driven gear 10 on one side.
