At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0041] Working process of this utility model:

[0042] The backstop is placed at a fixed point according to the requirements of the vehicle model.

[0043] The first step: first, put the bottom plate on the ground, turn the knob 606 according to the size of the wheel, drive the screw rod 601 to rotate, adjust the sliding block 602 through the thread on the screw rod, and drive the connecting rod 603 to move at the same time, so that one end of the connecting rod 603 pulls the fixing block 605, which can drive the mounting block 604 connected thereto to move, and drive the first limiting wheel 3 or the second limiting wheel 5 to move. The two knobs 606 can adjust the positions of the first limiting wheel 3 and the second limiting wheel 5 respectively, so that the first limiting wheel 3 and the second limiting wheel 5 are closely fitted with the wheel to prevent the wheel from retreating a small amount on the stopper, affecting the stop effect;

[0044] Step 2: When the car starts, the force driven by the wheels will be transmitted to the buffer plate 801, so that the buffer plate 801 squeezes the spring 803 and the telescopic rod 802, and the spring 803 and the telescopic rod 802 are compressed and deformed accordingly. The force driven by the wheels is absorbed by the deformation of the spring 803 and the telescopic rod 802, so as to prevent the bottom plate 1 from deflecting and affecting the anti-retraction effect. At the same time, the anti-skid pad 10 can increase the friction with the ground, so as to achieve a better fixing effect.

[0045] The third step: when storing, pull out the plug rod 704 to increase the distance between the plug rod 704 and the slot 703, then pull out the fixing block 605, remove the fixing blocks 605 on the first limiting wheel 3 and the second limiting wheel 5 respectively, and then lay each part flat, effectively reducing the height and volume of the device. Otherwise, insert the protrusion 702 into the groove 701, and then insert the plug rod 704 so that the plug rod 704 enters the slot 703, and then reassemble.

[0046] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
