The pair of protrusions 901 are fixed to the upper surface of the housing 1, and a rotating shaft 902 is rotatably installed between the protrusions 901. The rotating shaft 902 can rotate. The outer wall of the rotating shaft 902 is sleeved and fixed with the connecting frame 12, that is, when the rotating shaft 902 rotates, the connecting frame 12 and the cover plate 10 also rotate accordingly, and the rotating shaft 90 A worm wheel 903 is sleeved and fixed on the outer wall, a groove 16 is provided on the connecting frame 12, and the worm wheel 903 is located in the groove 16. A fixing box 905 is fixed on the upper surface of the housing 1, and a worm 906 is rotatably mounted on the fixing box 905, and the worm 906 is meshingly connected with the worm wheel 903.
