[0025] The sliding assembly includes two support plates 72 installed on one side of the fixed plate 71, a rotating shaft 74, two U-shaped plates 77 and two T-shaped sliding bars 73. The two support plates 72 are respectively located on the upper and lower sides of the fixed plate 71. One end of the rotating shaft 74 is rotatably connected to the fixed plate 71 through a bearing, and a matching gear 75 is installed on the other end. The two U-shaped plates 77 are respectively located at the upper and lower ends of the matching gear 75. A group of sliding teeth 76 meshing with the matching gear 75 is provided on the horizontal plate of the U-shaped plate 77. One side of the U-shaped plate 77 is fixedly connected to the T-shaped sliding bar 73, and the two T-shaped sliding bars 73 are respectively It is fixedly connected with half cover body 1 3 and half cover body 2 4. When half cover body 1 3 or half cover body 2 4 is pushed or pulled to one side, half cover body 1 3 or half cover body 2 4 can be separated or docked. For example, when half cover body 1 3 is pushed or pulled, the T-shaped sliding bar 73 connected to half cover body 1 3 will move with the U-shaped plate 77, and the sliding teeth 76 on the U-shaped plate 77 are engaged with the matching gear 75 to drive the other U-shaped plate 77 to move in the opposite direction, thereby moving half cover body 2 4 to the side opposite to the movement direction of half cover body 1 3 to complete the opening and closing operation of the protective cover.
