[0041] One end of the protective shell 2 is fixedly connected to one end of the fixing ring 32 , and the fixing ring 32 is used to install the protective shell 2 .

[0042] One end of the plurality of limiting grooves 34 is respectively connected to one end of the plurality of mounting grooves 33, and the bottom of the plurality of mounting grooves 33 is a through opening, so that when the fixing ring 32 is installed, the plurality of mounting grooves 33 are respectively sleeved onto the surface of the plurality of limiting blocks 35, thereby facilitating the installation of the protective shell 2.
