[0029] Further, the outer wall of the dustproof cover 315 is fitted with the inner wall of the slot 311, the outer wall of the sealing ring 317 is fitted with the inner wall of the sealing groove 318, and the material of the sealing ring 317 is rubber, which can improve the dustproof effect of the dustproof cover 315 on the detection box 319 and prolong the service life of the detection box 319.

[0030] Further, the number of roller shafts 316 is three, and the roller shafts 316 are evenly and equidistantly distributed on one end of the outer wall of the dustproof cover 315.
