[0040] The limiting assembly 32 includes a limiting link 321 and an intermediate connecting block 322 connected to one end of the limiting link 321, and a shift ring 323 is connected to the outer side of the intermediate connecting block 322, and a limiting positioning member 324 is connected to the inner side of the limiting link 321, and a first spring 325 is connected to one end of the limiting link 321, wherein one end of the limiting link 321 is fixedly connected to the intermediate connecting block 322, and the other end is fixedly connected to the first spring 325, and a shift ring 323 is connected to the outer side of the intermediate connecting block 322, and the intermediate connecting block 322 and the shift ring 323 are fixedly connected by a connecting rod, and the connecting rod is limitedly moved inside the positioning mounting seat 31 to ensure that the shift ring 323 does not appear when moving. In the case of rotation, the limiting positioning member 324 performs a limiting movement inside the limiting link 321, and at the same time, one end of the limiting positioning member 324 is connected to the connecting slot 1333; the limiting positioning member 324 includes a limiting positioning plate 3241 and a second limiting slider 3242 connected to one side of the limiting positioning plate 3241, and both ends of the limiting positioning plate 3241 are connected to a connecting moving block 3243, wherein the connecting moving block 3243 performs a limiting movement inside the limiting link 321 to ensure the stable movement of the limiting positioning plate 3241, and at the same time, the second limiting slider 3242 is connected to one end of the limiting positioning plate 3241 close to the outside, and the second limiting slider 3242 performs a limiting movement inside the connecting slot 1333.

[0041] The fixing member 33 includes a fixing rotating block 331 and a fixing boss 332 arranged on one side of the fixing rotating block 331, and a matching slot 333 is opened on the other side of the fixing rotating block 331, and a connecting shaft 334 is connected inside the matching slot 333, wherein the fixing rotating block 331 is as a whole engaged with the connecting slot 232 for engagement, and the fixing boss 332 arranged on the fixing rotating block 331 is matched with the fixing slot 233 for engagement, thereby ensuring the engagement and fixation between the fixing member 33 and the engaging assembly 23, and the size of the matching slot 333 is larger than the size of the positioning mounting seat 31, so that the matching slot 333 can be sleeved on the outer side of the positioning mounting seat 31, and the setting of the connecting shaft 334 is connected with the connecting seat connected to the positioning mounting seat 31, thereby ensuring that the fixing member 33 is rotatably connected to the outer side of the positioning mounting seat 31.

[0042] When the mounting cover unit 20 is installed, the first positioning groove 221 is aligned with the positioning block 123, so that the mounting cover body 21 slides into the installation from the entry groove 121. After that, the mounting cover body 21 reaches the limit position, at this time, the positioning block 123 is just located at the second positioning groove 222, and the mounting cover body 21 is pushed to make the positioning block 123 slide into the second positioning groove 222, completing the preliminary positioning of the mounting cover body 21. At this time, the locking assembly 23 is also locked with the fixing member 33 at the same time, so that the fixed rotating block 331 is locked with the connecting slot 232. Due to the setting of the second spring 34, the fixing boss 332 is locked with the fixing slot 233. At this time, the preliminary installation and positioning of the mounting cover unit 20 can be completed. At the same time, the shift ring 323 is pushed by the first spring 325 and the transmission of the limit connecting rod 321 and the middle connecting block 322 to block and limit the fixed rotating block 331;
