One end of the fastening bolt penetrates the support plate and is fixed to the slide plate. The use of the fastening bolt facilitates the fixation of the slide plate, so as to prevent the loosening of the protective cover and affect the protection effect.

[0010] In a preferred embodiment, the protective cover is provided with a movable handle fixed to the outer wall on one side. The worker can easily and quickly pull out the protective cover by holding the handle, which improves the disassembly efficiency of the protective cover.

[0011] In a preferred embodiment, the protective cover is provided with a stroboscopic warning light fixed to the outer wall. The stroboscopic warning light flashes at a certain frequency, has a strong visual impact, and can attract people's attention at a long distance. Therefore, the stroboscopic warning light can play a warning role and improve the safety of the worker.
