[0026] Specifically, the fixing component 33 includes a bolt 331, a square insert 332, a screw hole 333, and a square slot 334. A square insert 332 is located at the center of the upper end of the base plate 1. A square slot 334 corresponding to the square insert 332 is provided at the lower end of the central column 6. The square insert 332 and the central column 6 are fixedly connected by bolts 331. Screw holes 333 corresponding to the bolts 331 are provided inside the square insert 332 and at the upper end of the square slot 334.

[0027] By adopting the above technical solution, when fixing the base plate 1 and the center column 6, the square insert 332 at the upper end of the base plate 1 is inserted into the square slot 334 at the lower end of the center column 6, and then the connection and fixation between the base plate 1 and the center column 6 can be achieved by bolts 331 and screw holes 333.

When fixing the base plate 1 and the central column 6, the square insert 332 at the upper end of the base plate 1 is inserted into the square slot 334 at the lower end of the central column 6. The connection and fixation between the base plate 1 and the central column 6 can then be achieved through bolts 331 and screw holes 333.

[0029] Example 2

[0030] The difference between this embodiment and Embodiment 1 is that the top cover fixing mechanism 4 includes a fixing hole 42, a square groove 43, a fixing component 44, a knob 46, a screw 47, and a square block 48. A square block 48 is provided at the center of the lower end of the top cover body 5. A square groove 43 corresponding to the square block 48 is opened at the upper end of the central column 6. A fixing hole 42 is opened at the lower end of the side of the square groove 43. A screw 47 is threadedly connected to the inside of the square block 48. A knob 46 is provided at the upper end of the screw 47. A fixing component 44 is provided inside the lower side of the square block 48.

[0031] By adopting the above technical solution, when fixing the top cover body 5 and the central column 6, the square block 48 at the lower end of the top cover body 5 is inserted into the square groove 43 at the upper end of the central column 6. Then, the knob 46 is rotated, and the knob 46 drives the screw 47 to rotate and descend, so that the fixing component 44 and the fixing hole 42 are inserted into each other to fix the top cover body 5.

[0032] Specifically, the top cover fixing mechanism 4 also includes a positioning hole 41 and a positioning rod 45. The positioning rod 45 is provided on the lower side of the top cover body 5, and the positioning hole 41 corresponding to the positioning rod 45 is provided on the upper side of the central column 6.

[0033] By adopting the above technical solution, after the top cover body 5 is installed, the positioning rod 45 at the lower end of the top cover body 5 will be inserted into the positioning hole 41 at the upper end of the central column 6, which will improve the fixing effect of the top cover body 5.

[0034] Specifically, the fixing component 44 includes a limiting plate 441, a slider 442, a groove 443, a spring 444, a center rod 445, a fixing rod 446, and a limiting groove 447. A limiting groove 447 is formed inside the lower side of the square block 48. A fixing rod 446 is slidably connected inside the limiting groove 447. The limiting plate 441 is fixed to the surface of the fixing rod 446. Slider 442s are provided at the upper and lower ends of the limiting plate 441. A groove 443 corresponding to the slider 442 is formed on the side of the limiting groove 447. A center rod 445 is slidably connected inside the slider 442. A spring 444 is sleeved on the surface of the center rod 445 on the side of the slider 442. The inner side of the fixing rod 446 and the lower end of the screw 47 are both designed with an arc-shaped structure.

[0035] By adopting the above technical solution, by setting the inner side of the fixing rod 446 and the lower end of the screw 47 into an arc-shaped structure, when the screw 47 descends, it will squeeze the fixing rod 446 to slide outward. The fixing rod 446 drives the limiting plate 441 to slide inside the limiting groove 447. When the limiting plate 441 slides, it will drive the slider 442 to slide inside the sliding groove 443. At the same time, the slider 442 also slides on the surface of the central rod 445 and drives the spring 444 to compress. Meanwhile, the fixing rod 446 will slide out from the inside of the square block 48 and insert into the inside of the fixing hole 42 to achieve the fixing effect of the top cover body 5.

[0036] In this embodiment, when fixing the top cover body 5 and the central column 6, the square block 48 at the lower end of the top cover body 5 is inserted into the square groove 43 at the upper end of the central column 6. Then, the knob 46 is rotated, which drives the screw 47 to rotate and descend. By setting the inner side of the fixing rod 446 and the lower end of the screw 47 into an arc-shaped structure, when the screw 47 descends, it will squeeze the fixing rod 446 to slide outward. The fixing rod 446 drives the limiting plate 441 to slide inside the limiting groove 447, thus limiting the movement. When plate 441 slides, it will drive slider 442 to slide inside the groove 443. At the same time, slider 442 also slides on the surface of central rod 445, and drives spring 444 to compress. Meanwhile, fixing rod 446 will slide out from inside square block 48 and insert into fixing hole 42 to achieve the fixing effect of top cover body 5. When top cover body 5 is installed, positioning rod 45 at the lower end of top cover body 5 will be inserted into positioning hole 41 at the upper end of central column 6, which will improve the fixing effect of top cover body 5.

[0037] The working principle and usage process of this utility model are as follows: When replacing the annular outer shell body 2, the positioning strip 31 on the inner wall of the annular outer shell body 2 is inserted into the positioning groove 34 on the outer surface of the central column 6. This fixes the annular outer shell body 2. The anti-slip groove 32 on the outer wall of the annular outer shell body 2 prevents the metal wire from sliding on its surface. When fixing the base plate 1 to the central column 6, the square insert 332 at the upper end of the base plate 1 is inserted into the square slot 334 at the lower end of the central column 6. The connection and fixation between the base plate 1 and the central column 6 are then achieved using bolts 331 and screw holes 333. When fixing the top cover body 5 to the central column 6, the square block 48 at the lower end of the top cover body 5 is inserted into the square groove 43 at the upper end of the central column 6. Rotating knob 46 causes screw 47 to rotate and descend. By setting the inner side of fixing rod 446 and the lower end of screw 47 into arc-shaped structures, when screw 47 descends, it will squeeze fixing rod 446 to slide outward. Fixing rod 446 causes limiting plate 441 to slide inside limiting groove 447. When limiting plate 441 slides, it will cause slider 442 to slide inside sliding groove 443. At the same time, slider 442 also slides on the surface of central rod 445 and causes spring 444 to compress. Meanwhile, fixing rod 446 will slide out from inside square block 48 and insert into fixing hole 42 to achieve the fixing effect of top cover body 5. When top cover body 5 is installed, positioning rod 45 at the lower end of top cover body 5 will be inserted into positioning hole 41 at the upper end of central column 6, which will improve the fixing effect of top cover body 5.
