All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the protective casing comprises a protective casing 1 with an empty top, wherein the top of the protective casing 1 is provided with a plurality of mounting through holes 2. The surface of the protective shell 1 is respectively provided with a first notch 3, a second notch 4 and a ventilation notch. The inside mount pad 6 that is equipped with fixed connection of protecting sheathing 1, 6 surfaces of mount pad are equipped with a plurality of

stand

8, and 8 centers of a plurality of stand are equipped with heat dissipation through-hole 9. A shock absorption seat 7 is arranged above the mounting seat 6, a through output shaft through hole is formed in the centers of the mounting seat 6 and the shock absorption seat 7, and a driving bevel gear 10 connected in a rotating mode is arranged in the output shaft through hole. The protection casing 1 both sides are equipped with first recess 12, second recess 13 respectively, and the installation is equipped with transmission shaft 14 in first recess 12 and the second recess 13, and transmission shaft 14 is close to second recess 13 end surface and is equipped with second mount 15, and second mount 15 passes through bearing swing joint with transmission shaft 14, and the center department cover of transmission shaft 14 is equipped with fixed connection's transmission bevel gear 11, and transmission bevel gear 11 is connected with the meshing of driving bevel gear 10, it still all is equipped with fixed connection's reinforcing piece to drive bevel gear 10 and transmission bevel gear 11 surface.
