The through hole 7 is opened inside the threaded rod 6 at one end away from the conical block 4, and the through hole 7 has the function of increasing the heat dissipation for the threaded rod 6.

[0029] Reference Figures 3 and 4 , a plurality of transverse holes 9 are provided inside the shell component 1 to increase the heat dissipation effect, and enhance the contact area between the air and the inside of the shell component 1 while dissipating heat through the through hole 7. A side hole 8 is provided on the side of the inside of the shell component 1 away from the transverse hole 9. Both the side hole 8 and the transverse hole 9 are small-diameter slots surrounding the through hole 7, which are also used to increase the heat dissipation effect.
