[0038] When it is necessary to tighten the belt 2 in the installation structure: first remove the positioning assembly 22, then remove the first cover plate 5 on the upper part of the first storage cavity of the shell 1, so that the first cover plate 5 can be pulled out of the shell 1, and after the first cover plate 5 is taken out, the transmission wheel 6 arranged inside the first storage cavity can be taken out, and after the transmission wheel 6 is taken out, the belt 2 can be quickly pulled out of the first storage cavity, and the belt 2 can be pulled out later, so that the belt 2 can be quickly pulled out and adjusted only after the first cover plate 5 and the transmission wheel 6 are taken out, and there is no need to disassemble the entire auxiliary transmission box 100 before adjusting the belt 2, which will reduce the working time required for the tightening operation of the belt 2 and improve the working efficiency;

[0039] Subsequently, when the belt 2 is pulled to the connection position with the connecting piece 3, one end of the belt 2 is further taken out from the connecting piece 3, and then one end of the belt 2 is shortened. When the belt 2 is shortened, the shortened end can be installed back into the connecting piece 3, and the belt 2 is re-formed into a ring structure. Subsequently, the belt 2 is put back into the first storage cavity, and then the transmission wheel 6 is installed to make the belt 2 mesh with the transmission wheel 6, so as to achieve the belt tightening operation by reducing the overall length of the belt 2.

[0040] Preferably, when the guide rail member 1 needs to be extended, the guide rail installation opening 7 is provided to quickly detach the guide rail member 1 from the auxiliary transmission box 100, so that multiple guide rail members 1 can be spliced ​​and assembled by connecting screws later. When the guide rail member 1 is extended, the belt 2 needs to be connected to the external belt member through the connecting member 3 at the same time, so that the belt 2 can be extended as a whole synchronously, ensuring the normal use of the present structure;

[0041] When the structure needs to be transported later, the assembled guide rail member 1 and the guide rail mounting opening 7 are first disassembled from the auxiliary transmission box 100, and then the multiple sections of the guide rail member 1 can be disassembled by releasing the connecting screws, so as to realize the segmented transportation of the guide rail member 1.

A third positioning groove 182 is also provided on the outer periphery of the third cover plate 18, and the third positioning groove 182 and the third positioning boss 173 cooperate with each other.

[0051] The third cover plate 18 can be quickly assembled and disassembled by the cooperation of the hook 181 and the socket 172 , and subsequently, the third positioning boss 173 and the third positioning groove 182 can be cooperated to prevent the third cover plate 18 from being offset when installed in the second storage cavity.

[0052] Preferably, a guide rail installation opening 7 is also opened on the side of the main transmission box 200 close to the guide rail member 1, so that the guide rail member 1 can be quickly removed from the main transmission box 200, so that multiple guide rail members 1 can be subsequently spliced ​​and assembled through connecting screws. When the guide rail member 1 is extended, the belt 2 needs to be connected to the external belt member through the connecting member 3 at the same time, so that the belt 2 can be extended as a whole, ensuring the normal use of this structure.

[0053] As attached Figure 1 , 2As shown in Figures 3, 8, 9 and 10, the connecting member 3 includes a first clamping portion 31, a connecting portion 33 and a second clamping portion 32. The first clamping portion 31 is clamped at one end of the belt 2, and the second clamping portion 32 is clamped at the other end of the belt 2. The first clamping portion 31 and the second clamping portion 32 are connected via the connecting portion 33. Subsequently, a first clamping groove 34 is provided inside the first clamping portion 31 and the second clamping portion 32. Teeth 21 are provided on the inner side of the belt 2, and the teeth 21 are meshed in the first clamping groove 34, so that the two ends of the belt 2 are arranged in the first clamping portion 31 and the second clamping portion 32 through the meshing of the teeth 21 and the first clamping groove 34. In this way, the belt 2 and the connecting member 3 can be quickly assembled and disassembled by the mutual meshing of the teeth 21 and the first clamping groove 34. At the same time, the meshing method can ensure the stability of the belt 2 and the connecting member 3 when they are combined.
