The heat dissipation sleeve 6 is provided with grooves for providing a heat dissipation area, thereby further improving the cooling effect.

The fastening rubber band 12 will be tightly attached to the annular groove through the elastic reset effect, and then the bolt assembly 21 is tightened again, and the corresponding pressure frame 20 is driven to move synchronously by the two half-ring frames 18, so that the pressure frame 20 can press the ends of the fastening rubber band 12 and the rubber sleeve 11 against the protective sleeve 13 to form an anti-falling sealing structure. At this time, the rubber sleeve 11 can cover the splicing of the two soft connection structures to form a dustproof structure.
