The guide grooves provided in the lower frame 61 are divided into a driving door guide groove 621 and a driven door guide groove 611, which are arranged in parallel and have openings facing downward.

Specifically, the section of the guide main body of the guide assembly in the vertical direction is in an inverted hook shape; the guide pulley is rotationally connected to the free end of the guide main body, and the rotational axis of the guide pulley is vertically arranged; the guide assembly further comprises a guide connecting block, and the lower part of the driving door 21 or the driven door 31 is provided with a mounting hole for mounting a guide body; the guide body is provided with a plug connector which is used for being matched with the mounting hole in an inserting mode, the guide connecting block is located on the other side of the driving door 21 or the driven door 31 relative to the guide body, and the guide connecting block is clamped on the driving door 21 or the driven door 31 in a matched mode with the guide body through threaded fastening.

As shown in fig. 5 and 6 in particular, since the positions of the driving door 21 and the driven door 31 are different, the driving door guide assembly and the driven door guide assembly are divided into a driving door guide assembly and a driven door guide assembly, wherein the driving door guide assembly includes a driving door guide main body 622, a driving door guide pulley 621 and a driving door guide connection block, the driven door guide assembly includes a driven door guide main body 632, a driven door guide pulley 631 and a driven door guide connection block 633, the driving door guide assembly 62 and the driven door guide assembly 63 have substantially the same structure, and only have a small difference in size in order to adapt to the positions of the driving door 21 and the driven door 31. Here, the following door guide unit 63 is taken as an example, and a specific structure of the guide unit will be described.

As shown in fig. 5 and 6, the driven door guide body 632 is substantially in a shape of a "J" and may be divided into an upper mounting portion and a lower mounting portion, the upper mounting portion is formed with a plug, the plug is adapted to a mounting hole of the driven door 31, and can be inserted into the mounting hole of the driven door 31 to fix the driven door guide assembly 63. The screw thread counter bore is arranged in the middle of the plug, the corresponding through hole is arranged on the driven door guide connecting block 633, the bolt can pass through the driven door guide connecting block 633 and then is screwed into the screw thread counter bore in the middle of the plug, then the driven door guide connecting block 633 is pushed to one side face of the driven door 31, the driven door 31 can be clamped by the driven door guide connecting block 633 and the driven door guide main body 632 along with the screwing of the bolt, and therefore the driven door guide assembly 63 can be fixed on the driven door 31.
