[0029] The components inside the tube body 1 are correspondingly installed inside the isolation inner tube 5 , and the insulating rubber pad 6 inside the isolation inner tube 5 can also provide insulation protection for the outside of the tube body 1 .

[0030] A switch plate 10 is fixedly mounted on the outside of the tube body 1 , and a switch cover 11 is arranged on the switch plate 10 .
