The rectangular plate 42 is threadedly connected to the lower end of the metal connecting rod 43.

[0062] As can be seen from the above, when in use, the metal connecting rod 43 is pushed upward, and the metal connecting rod 43 passes through the middle position of the sealing cover plate 41. The metal connecting rod 43 can drive the rectangular plate 42 to move upward, so that the top surface of the rectangular plate 42 and the bottom surface of the sealing cover plate 41 are connected.

[0063] The sealing cover plate 41 is pushed upward, and the sealing cover plate 41 can drive the metal connecting rod 43 to move upward, so that the metal connecting rod 43 penetrates the inner wall surface of the lower end of the metal frame 1333, and the metal connecting rod 43 slides on the inner wall surface of the limiting plug-in block 1335.

[0064] The limiting sleeve 44 is pushed to move downward, and the limiting sleeve 44 and the upper end of the metal connecting rod 43 are movably connected, and the inner wall surface of the limiting sleeve 44 is provided with an internal thread groove, and the limiting sleeve 44 and the external thread on the upper end of the metal connecting rod 43 are engaged, so that the limiting sleeve 44 and the metal connecting rod 43 can be threadedly connected.

[0065] When the metal connecting rod 43 moves upward, the metal connecting rod 43 can drive the sealing cover plate 41 to move upward, so that the sealing cover plate 41 is connected to the bottom surface of the storage shell 31, so that the chemical desiccant can be stored.

[0066] Pushing the connecting block 45 to move backward so that the connecting block 45 is inserted into the limiting plug-in block 1335 and the metal connecting rod 43 can determine the position of the sealing cover plate 41 and effectively prevent the chemical desiccant on the surface of the sealing cover plate 41 from falling off.
