The bottom plate 61 is combined with the drying box body 4 by a conventional method, the top plate 63 is combined with the box cover 5 by a conventional method, the adjusting cylinder 62 is combined with the bottom plate 61 and the top plate 63 by a conventional method, and the adjusting cylinder 62 is operated and shortened. The state is changed to an extended state, so that the top plate 63 and the box cover 5 move upward vertically, so that the heating wire 71 located in the drying box body 4 is exposed, which is convenient for maintenance; the sealing component includes a limiting frame 43 installed on the inner wall of the drying box body 4 and a sealing frame 52 installed on the bottom surface of the box cover 5.
