When the supporting plate 22 moves from the top side frame to the bottom side frame of the supporting frame, the supporting surfaces are all in an upward state, so that the ultraviolet disinfection lamp strip can be convenient for disinfecting the supporting surfaces of the supporting plate 22.

As shown in fig. 4 and 5, optionally, a limiting part 4 is further disposed in the accommodating cavity 11, and the limiting part 4 includes a fixing plate 41, a spring 42 and a triangle 43;
