[0031] The fixing device includes a first mounting block 20 and a second mounting block 21. The first mounting block 20 is fixedly connected to the side wall of the hollow box body 11. The first mounting block 20 is connected to the second mounting block 21 through a second spring. A second latch 22 is fixedly connected to one side of the second mounting block 21.
[0032] A handle 23 is fixedly connected to the lower portion of the second mounting block 21 , and an opening 24 for the handle 23 to pass through is formed on the hollow box body 11 .
[0033] The protective cover 1 is provided with a plurality of first rectangular through holes 10 , and the back plate 4 is provided with a plurality of second rectangular through holes.
[0034] A transverse sponge strip 18 and a longitudinal sponge strip 17 are bonded to the upper portion of the back plate 4 .
