Embodiment two

[0027] As shown in Figure 6As shown, on the basis of Embodiment One, the locking assembly 5 comprises a fixed plate 501, the top of which is fixedly installed with a locking plate one 502 and a plurality of locking plate twos 503. When the box cover 301 is tightly clamped with the arc-shaped limiting block 200, the locking plate one 502 abuts against one end of the U-shaped rod 302 and locks the box cover 301. After the box cover 301 is horizontally slid, the plurality of locking plate twos 503 can be inserted into the clamping groove 3021 after being vertically moved and lock the box cover 301. The locking assembly 5 further comprises an adjusting screw 504, which is rotatably connected with the protective cover 4. The fixed plate 501 is in sliding fit with the inner wall of the protective cover 4 and is threadedly sleeved on the adjusting screw 504. One end of the adjusting screw 504 is fixedly installed with a handle 505. The inner wall of the protective cover 4 is fixedly installed with a plurality of limiting rods 401. The fixed plate 501 is sleeved on the plurality of limiting rods 401.
