Here, the first box a201 and the first box B are arranged in pair, and the first outer telescopic assembly B213 is controlled to extend the first outer telescopic assembly B213, so that the first box a201 and the first box B are gradually folded, and the first box a201 and the first box B are folded in half, thereby reducing the floor area.

As shown in fig. 6, 7, 11 and 12, the spur roller 204 is disposed at upper and lower ends of the first casing a201, the second casing a203, the first casing B and the second casing B, respectively, and the spur belt 205 is disposed outside the spur roller 204. The positive belt 205 is wound on the outer side of the positive roller 204, and when the positive belt 205 rotates, the positive roller 204 also generates a rotation motion. The power assembly is fixedly arranged on the frame 1 and used for driving the positive belt 205 to rotate. The power assembly is not shown in the figure because it can directly use a rotating motor, and the rotating motor and the positive belt 205 are driven to move. The power assembly is of conventional design and will not be described in greater detail herein.

Referring to fig. 7 and 11, second pressing rollers a206 are disposed above and below the second casing a203, respectively, by pressing assemblies, for pressing the positive belt 205 onto the positive roller 204. The second platen roller a206 is indispensable, and can ensure that when the second casing a203 retreats into the first casing a201, the positive belt 205 on the second casing a203 can enter the first casing a201 along with the second casing a203, and the positive belt 205 is prevented from being accumulated outside the first casing a 201. Here, it is required that the first casing a201 is larger than the distance between the second casing a203 and the second platen a 206.
