[0023] The specific implementation method is as follows: when using the utility model, the lower end of the first turnover box 211 needs to be placed inside the base 1 first. When the first turnover box 211 is placed, the pulling rod 224 can be pulled. After the pulling rod 224 is pulled, the pulling plate 222 is driven to move backward to squeeze the two groups of damping spring groups 228. When the two groups of damping spring groups 228 move backward at the same time, the internal space at the upper end of the base 1 increases, and the first turnover box 211 can be placed inside the base 1. When the first turnover box 211 is placed, the pulling rod 224 is released, and the damping spring group 228 rebounds and drives the positioning block 223 to move forward. The positioning block 223 moves forward and returns to its original position and enters the slot 227 to limit and fix the first turnover box 211, thereby preventing the first turnover box 211 from being In order to solve the problem that the first turnover box 211 is displaced and falls due to the bumps during operation, when multiple sets of second turnover boxes 212 need to be installed on the upper end of the first turnover box 211, the lower end of the upper mounting column 217 set at the lower end of the second turnover box 212 can be docked and installed on the upper end of the lower mounting column 2101. After the docking of the upper mounting column 217 and the lower mounting column 2101 is completed, the assembly sleeve 218 is rotated to connect and install the upper mounting column 217 and the lower mounting column 2101 through the assembly sleeve 218, thereby avoiding the problem that the placement stability of the two sets of first turnover boxes 211 and the first turnover boxes 211 are poor when they are stacked and transferred, resulting in reduced convenience in the transfer of the boxes. The device further improves the portability of the entire device through a simple assembly, stacking and moving method.

[0024] Working principle of the utility model: When using the utility model, the lower end of the first turnover box 211 needs to be placed inside the base 1 first. When the first turnover box 211 is placed, the pull rod 224 can be pulled. After the pull rod 224 is pulled, the pull plate 222 is driven to move backward to squeeze the two groups of damping spring groups 228. When the two groups of damping spring groups 228 move backward at the same time, the internal space at the upper end of the base 1 increases, and the first turnover box 211 can be placed inside the base 1. When the first turnover box 211 is placed, the pull rod 224 is released, and the damping spring group 228 rebounds to drive the positioning block 223 to move forward, and the positioning block 223 Move forward and return to the original position to enter the slot 227 to limit and fix the first circulating box 211 to avoid the problem of the first circulating box 211 being displaced and falling due to the bumps during operation. When multiple sets of second circulating boxes 212 need to be installed on the upper end of the first circulating box 211, the lower end of the upper mounting column 217 set at the lower end of the second circulating box 212 can be connected and installed on the upper end of the lower mounting column 2101. After the upper mounting column 217 and the lower mounting column 2101 are connected, the assembly sleeve 218 is rotated to connect and install the upper mounting column 217 and the lower mounting column 2101 through the assembly sleeve 218.
