[0031] As a further embodiment of the above technical solution: the rubber air hole 422 is provided with a plurality of rubber air holes 422, the vertical section shape of the rubber air hole 422 is rectangular, the rubber air hole 422 is circularly arrayed at the lower end of the sealing ring 421, when the fixed device 4 is inserted, the rubber air hole 422 is compressed and deformed to discharge gas, adapt to the deformation process of the sealing ring 421;When the fixed device 4 is installed, the rubber air hole 422 restores to the original state, which helps to maintain the sealing performance of the sealing ring 421, and can also buffer the influence of external air pressure change on the sealing structure to some extent, further enhancing the reliability of sealing;

[0032] As a further embodiment of the above technical solution: the sealing device 42 includes sealing ring 421, rubber air hole 422 is set in the lower end of the sealing ring 421, the sealing ring 421 is arranged between the upper end of the guide rod 41 bottom and the upper end of the mounting block 3, effectively preventing foreign matter such as dust, water vapor from invading the inside of octagonal line box 2;

[0033] As a further implementation of the above technical solution: the extrusion spring 13 and the limiting block 14 are arranged at one half of the installation groove 12, the inner side of the installation frame 11 is provided with a cavity connected with the inner side of the installation groove 12, the extrusion spring 13 and the limiting block 14 are arranged in the cavity, and the outer side of the limiting block 14 is slidingly connected in the cavity, which can adaptively provide space for the guide rod 41 and its connecting components, and smooth installation is realized.

[0034] As a further implementation of the above technical solution: the center points of the guide rod 41, the sliding rod 43 and the guide block 45 are located on the same vertical line, the center points of the guide block 45 and the installation groove 12 are located on the same vertical line, the sliding rod 43 is arranged between the guide rod 41 and the guide block 45, and as the guide rod 41 moves, the guide block 45 is driven to interact with the limiting block 14 according to a predetermined trajectory, reliable clamping of the fixing device 4 is realized, and it is ensured that the fixing device 4 can be smoothly separated.

[0035] As a further implementation of the above technical solution: the vertical cross section of the sliding block 44 is hexagonal, the upper end face and the lower end face of the sliding block 44 are equal in diameter to the lower end face of the guide rod 41 and the upper end face of the guide block 45, the lower end of the guide rod 41 is arranged in an arc shape, and in the disassembly operation, the limiting block 14 is guided to extend and retract according to its shape trajectory through close cooperation with the limiting block 14, the jamming state of the limiting block 14 to the guide block 45 is broken, and thus quick disassembly of the fixing device 4 is realized.

[0036] As a further implementation of the above technical solution: the lower end of the fixing device 4 penetrates through the installation block 3 and is fixed to the inner side of the installation groove 12, the vertical cross section of the guide rod 41 is T-shaped, and the lower end of the guide rod 41 is arranged above the limiting block 14, so as to avoid damage to the internal structure of the fixing device 4 due to misoperation insertion too deep.

[0037] Workflow: The octagonal box 2 is placed above the metal butt frame 1, the mounting block 3 is aligned with the mounting slot 12 on the mounting frame 11, the lower end of the fixing device 4 is inserted into the mounting slot 12 through the hole of the mounting block 3, and the guide rod 41 plays a guiding role during the insertion process. Because the vertical section of the guide rod 41 is T-shaped, the larger part of the upper end can prevent the fixing device 4 from being inserted too much. At the same time, the arc design of the lower end of the guide block 45 facilitates the pushing of the limiting block 14 when it comes into contact with the limiting block 14. When the lower end of the guide block 45 comes into contact with the limiting block 14 and exerts pressure, the limiting block 14 is compressed and extruded in the cavity, and slides inward to make room for the descent of the guide rod 41 and its connected components. The slide rod 43 descends with the guide rod 41. Because the vertical section of the guide block 45 is trapezoidal, the limiting block 14 is extruded according to the shape trajectory. When the slide rod 43 moves downward a certain distance to the upper part of the guide block 45, the limiting block 14 will be extruded by the elastic force of the compression spring 13, and the limiting block 14 will be bounced back to the original position. At the same time, the guide block 45 will be jammed, preventing the fixing device 4 from popping up, thereby firmly fixing the octagonal box 2 on the metal butt frame 1. At the same time, the sealing device 42 is in the process of the guide rod 41 descending. When the fixing device 4 is inserted, the sealing ring 421 between the upper end of the guide rod 41 and the upper end surface of the mounting block 3 is extruded from both sides. Under the action of pressure, the sealing ring 421 deforms, and the rubber air hole 422 in the lower end is compressed and deformed, and the gas is discharged from the air hole. When the fixing device 4 is installed, the rubber air hole 422 returns to its original shape, providing good sealing effect to prevent dust, water vapor and other impurities from entering the octagonal box 2 through the connection between the fixing device 4 and the mounting block 3.

[0038] When the fixing device 4 needs to be disassembled, the guide rod 41 needs to be pressed downward, and the limiting block 14 will drive the slide block 44 to slide to the top of the slide rod 43. Continue to press, the slide block 44 will extrude the limiting block 14, and the limiting block 14 will be stretched to the upper end surface of the slide block 44 according to the shape trajectory of the slide block 44. At this time, the slide block 44 slides downward, pulling the guide rod 41 upward. At this time, the limiting block 14 will be stretched to the lower end of the guide block 45 according to the shape trajectory of the slide block 44 and the guide block 45, and the fixing device 4 will be disassembled from the metal butt frame 1, realizing quick disassembly.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
