Further, a high wear-resistant coating layer is arranged on the shell.
Has the advantages that: through being provided with high wear-resistant coating layer, high wear-resistant coating can play the guard action to the shell, prevents that external factors from damaging the shell, prolongs the life of shell.
Further, the housing may be made of an aluminum alloy material.
Has the advantages that: the aluminum alloy material has the advantages of light weight, good corrosion resistance and good heat dissipation effect.
