Handles are fixedly connected to both ends of the front side of the protective plate 4 to facilitate maintenance personnel to control the movement of the protective plate 4 and facilitate maintenance and replacement.

[0045] The two mounting components 5 are used in conjunction with the door panel 2 and are arranged on the rear side of the protective plate 4. The mounting components 5 include a block 51, a guide groove 52, a telescopic rod 53 and a fixing ball 54. The block 51 is fixedly connected to the rear side of the protective plate 4, the guide groove 52 is used in conjunction with the block 51 and is opened on the front side of the door panel 2, the upper and lower inner walls of the guide groove 52 are both provided with guide holes, the telescopic rod 53 is fixedly connected to the inner wall of the guide hole, a spring is sleeved on the telescopic rod 53, the fixing ball 54 is used in conjunction with the block 51 and is fixedly connected to one end of the telescopic rod 53, and the two ends of the spring are fixedly connected to the telescopic rod 53 and the fixing ball 54 respectively. When the block 51 is inserted into the guide groove 52, the fixing ball 54 will abut against the side wall of the block 51, and by bringing the protective plate 4 close to and close to the door panel 2, the block 51 is inserted between the two fixing balls 54, and under the action of the telescopic rod 53 and the spring, the fixing ball 54 will generate a thrust on the block 51 to fix it to the protective plate 4, thereby enhancing the stability of the device.

[0046] A plurality of buffer components 9 are used in conjunction with the protective plate 4 and are arranged inside the door panel 2. The buffer components 9 include a fixed rod 91, a slider 92, a buffer spring 93 and a connecting rod 94. The upper and lower ends of the fixed rod 91 are fixedly connected to the inner wall of the door panel 2. The fixed rod 91 is sleeved with two sliders 92 used in conjunction with the door panel 2. The sliders 92 are slidably connected to the side walls of the fixed rod 91. The sliders 92 are slidably connected to the inner wall of the rear side of the door panel 2.
