[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 , including: a cart box 1, a cart handle 2 welded and fixed at the bottom of the cart box 1, and running wheels 6 arranged under the cart box 1. The bent parts of the two sets of cart handles 2 are located at the lower part of the cart box 1 and are fixed to the cart handles 2. At the same time, the bottom of the cart handle 2 extends downward and connects to the supporting leg 3, and the other end of the supporting leg 3 is tilted and extended upward and fixed to the bottom of the cart box 1. The supporting leg 3 and the running wheels 6 are used to support the ground, so that the cart box 1 can be kept in a relatively stable state.

[0026] The transverse wall plate 8 is arranged below the cart box 1, wherein the upper end of the support arm 4 fixes the support arm 4, and the top of the support leg 3 is fixed to the bottom of the cart box 1, and the cart handle 2, the support leg 3 and the support arm 4 are oppositely distributed on both sides of the bottom of the cart box 1 to maintain the stability of the support of the cart box 1. The surface of the transverse wall plate 8 is provided with a movable longitudinal groove 10, and the bottom of the movable longitudinal groove 10 is connected to the movable transverse groove 13, and the grooves of the movable longitudinal groove 10 and the movable transverse groove 13 are connected, and the groove cross-sections of the movable longitudinal groove 10 and the movable transverse groove 13 are L-shaped. Due to the center of the walking wheel 6 A rotating shaft with a hollow structure is provided in the part, and a positioning rod 9 can be inserted into the hollow part of the rotating shaft. During assembly, the front end of the positioning rod 9 passes through the transverse wall plate 8 and extends into the hollow part of the rotating shaft. The two sets of transverse wall plates 8 are firmly restricted at the two ends of the rotating shaft by the end of the positioning rod 9, and the rotating shaft and the running wheel 6 rotate. In order to further improve the stability of the running wheel 6, a lower pressing plate 7 is provided between the rotating shaft and the transverse wall plate 8. The lower pressing plate 7 is an arc-shaped plate structure sleeved on the upper part of the positioning rod 9, and the top of the lower pressing plate 7 is fixed with a reinforcing plate 5, and the top of the reinforcing plate 5 is fixed to the surface of the cart box part 1;

[0027] The anti-dumping stopper 11 is arranged on the side of the running wheel 6 away from the cart box portion 1, and the two ends of the anti-dumping stopper 11 are fixed with adjustment rods 12 extending into the movable transverse groove 13; the anti-dumping stopper 11 can extend into the gap between the running wheel 6 and the transverse wall plate 8, and the adjustment rod 12 is moved downward from the top opening of the movable longitudinal groove 10, and when the adjustment rod 12 reaches the bottom end of the movable longitudinal groove 10, the adjustment rod 12 is moved laterally in the groove of the movable transverse groove 13, so that the use position of the anti-dumping stopper 11 can be changed, and because the diameter of the adjustment rod 12 is smaller than the inner diameter of the movable longitudinal groove 10 and the movable transverse groove 13, the adjustment rod 12 can not only be moved, but also rotated, thereby changing the use angle of the anti-dumping stopper 11.
