Positioning blocks 5 are arranged on the side walls on both sides of the shell of the protective shell 1, and external elastic pieces 2 are symmetrically inserted on the side walls on both sides of the protective shell 1;

[0024] Among them, through holes 21 are opened on the plate body of the external elastic piece 2, and the through holes 21 can be inserted on the positioning blocks 5. Elastic piece contacts 22 are arranged on the upper end plate body of the external elastic piece 2. The plate body part of the external elastic piece 2 provided with the elastic piece contacts 22 is inserted into the protective shell 1. A pressing plate 3 is installed on the surface of the other plate body of the external elastic piece 2 away from the protective shell 1, and a fixing bolt 4 is installed on the pressing plate 3, and the fixing bolt 4 can press and hold the pressing plate 3.

[0025] In addition, sockets 12 are symmetrically opened at the tops of the side walls on both sides of the shell of the protective shell 1, and the sockets 12 communicate with the inner cavity of the protective shell 1. Limit convex plates 11 are symmetrically opened at the bottoms of the side walls on both sides of the shell of the protective shell 1. The external elastic pieces 2 are installed between the limit convex plates 11, and the limit convex plates 11 play a role in limiting, ensuring the accurate installation position of the external elastic pieces 2 and preventing deviation.

[0026] Among them, a mounting hole 31 is opened in the middle of the surface of the plate body of the pressing plate 3 away from the protective shell 1, and positioning holes 33 are symmetrically and penetratingly opened on the surface located in the mounting hole 31. A limit plate 32 is arranged at the top end of the plate body of the pressing plate 3, and the limit plate 32 plays a role in limiting.

[0027] In addition, the limit plate 32 is arranged on the upper surface of the plate body of the external elastic piece 2, and the fixing bolt 4 can pass through the mounting hole 31, and the limit plate 32 will abut against the upper surface of the plate body of the external elastic piece 2.

[0028] Among them, a convex block 51 is arranged on one side of the positioning block 5, a bolt hole 53 is opened on the positioning block 5, positioning columns 52 are symmetrically arranged on the surface of the positioning block 5 at the bolt hole 53, the diameter of the column body of the positioning block 5 is the same as the diameter of the through hole 21, and the diameter of the positioning column 52 is the same as the diameter of the positioning hole 33. The fixing bolt 4 can be screwed into the bolt hole 53, and the positioning column 52 is convenient for positioning the pressing plate 3 and ensures that the position of the pressing plate 3 will not change.

[0029] In addition, a silicone pad 41 is sleeved on the surface of the head of the fixing bolt 4 facing the bolt, and the silicone pad 41 can prevent the fixing bolt 4 from scratching the surface at the mounting hole 31.
