[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it is necessary to understand 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 invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0033] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0034] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

In this technical solution, the groove width of the fifth groove 9 is less than the groove width of the seventh groove 8. The fifth groove 9 is connected to the seventh groove 8. The fixing member 4 can be a pin, through the seventh groove 8 and the fifth groove 9, the end portion is located in the seventh groove 8, and the fixing member 4 is limited by the seventh groove 8, which ensures the normal movement of the fixing member 4 and prevents the fixing member 4 from falling.

[0042] In some embodiments, the bottom of the fifth groove 9 is provided with a sixth groove 7, and the sixth groove 7 is provided with a driving member 6, and the driving member 6 is used to drive the fixing member 4 to move along the depth direction of the fifth groove 9. In this technical solution, the sixth groove 7 is provided at the bottom of the seventh groove 8, and the sixth groove 7 is connected to the seventh groove 8. The driving member 6 adopts an electromagnet, and a first induction unit can be provided in the second groove 17. When the connecting member 2 extends into the second groove 17, the induction unit senses the connecting member 2, thereby controlling the electromagnet to be energized. Under the action of magnetic force, the fixing member 4 moves toward the bottom of the groove until it is adsorbed on the electromagnet. A second induction unit is provided at the fifth groove 9. When the connecting member 2 moves to be opposite to the fifth groove 9, the electromagnet is controlled to be de-energized, and the fixing member 4 moves downward under the action of gravity until it is partially inserted into the fourth groove 15, completing the installation of the two adjacent main bodies 1. Of course, the driving member 6 can also be adopted in other ways, as long as it can drive the fixing member 4.

[0043] When disassembling two adjacent main bodies 1, first control the electromagnet to be energized. Under the action of magnetic force, the fixing member 4 moves toward the bottom of the groove until it is adsorbed on the electromagnet. At this time, the fixing member 4 is pulled out from the fourth groove 15, and then the connecting member 2 moves in the sliding groove toward the second groove 17 until it is moved into the second groove 17 and taken out. The disassembly method of the fixing groove is opposite to the installation method, and the disassembly of the two adjacent main bodies 1 is completed.

[0044] Furthermore, a power switch for the electromagnet may be provided on the main body 1. When the main body is not assembled, the power switch is used to cut off the power to the electromagnet, thereby saving energy and avoiding waste of resources.

[0045] In some embodiments, along the circumference of the third section 13, the outer peripheral wall of the third section 13 is provided with a thirteenth groove 25, and a plurality of balls are provided in the thirteenth groove 25.
