[0012] In some preferred embodiments, a second mounting hole is formed on the first plate, and one end of the screw passes through the second mounting hole and is threadedly connected to the output shaft of the motor.

[0013] In some preferred embodiments, the first mounting hole and the second mounting hole are both oval holes.

[0014] The beneficial effects of the utility model are as follows: when the utility model is used, the PC material of the original ball cover is changed to tempered glass. The tempered glass is a prestressed glass with high strength. When the tempered glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity, enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc., and effectively avoiding the problem that the glass fiber reinforced plastic is scratched by the windshield wiper, and avoiding the problem that the ball cover of the existing mining spherical core camera is made of PC material, and the wiper will scratch the surface of the ball cover after improper use, causing the camera's detection accuracy to decrease, and in serious cases affecting the safety of the detection occasion.
