[0062] A connecting rod 403, the connecting rod 403 is fixedly connected to the lower side of the upper limit plate 401;

[0063] A lower limit plate 404, which is fixedly connected to the bottom of the fixing box 4, and a connecting rod 403 is slidably connected inside the lower limit plate 404;

[0064] The contact piece 405 is fixedly connected under the connecting rod 403. The function brought about by pulling the contact piece 405 downwards is to drive the connecting rod 403, the upper limit plate 401 and the latch 402 to move downwards.

[0065] Among them, the shielding protection component also includes:

[0066] A limit spring 406, which is sleeved on the outside of the connecting rod 403, wherein the upper end of the limit spring 406 is fixedly connected to the lower limit plate 401, and the lower end of the limit spring 406 is fixedly connected to the lower limit plate 404;
