The surface of the can body 1 is provided with a connecting port 3 that protrudes upward and is connected to the can lid 2. On both sides of the connecting port 3, there are fastening members for tightly connecting the can lid 2 and the connecting port 3. The fastening members include first adjusting bolts 4 disposed on both sides of the connecting port 3 and snapped into the waist of the connecting port 3. The top of the first adjusting bolt 4 is provided with an arc-shaped groove and a convex rib, and the arc-shaped groove and the convex rib are connected in series. The tail of the first adjusting bolt 4 is connected to a vertically arranged connecting bolt 5. The other end of the connecting bolt 5 is connected to a second adjusting bolt 6. The inner side of the end of the second adjusting bolt 6 is arc-shaped, and the end of the second adjusting bolt 6 is hook-shaped and snapped onto the surface of the can lid 2. The bottom of the can body 1 is provided with a moisture-proof component for absorbing the moist air inside the can body 1. The moisture-proof component includes an arc-shaped rod 7 erected at the bottom of the can body 1. Both ends of the arc-shaped rod 7 abut against the inner wall of the can body 1, and the bottom is connected to an elastic airbag 8. Both sides of the elastic airbag 8 are respectively connected to a sleeve 9. One end of the sleeve 9 is connected to the elastic airbag 8 in a through manner, and the other end is slidably connected to a movable rod 10. The connection between the movable rod 10 and the sleeve 9 is in a closed state. The top end of the movable rod 10 is provided with a puncture head 11. The lower part of the elastic airbag 8 is snapped into the center of the surface of an arc-shaped ring 12. The bottom of the elastic airbag 8 is provided with a cross support frame 13. On both sides of the waist of the cross support frame 13, there are respectively support rods 14. The end of the support rod 14 is provided with a support head 15 that abuts against the inner wall of the arc-shaped ring 12. After being pressed, the puncture head 11 is inserted into the pore 16 at the bottom of the can body 1 and presses a clamping hook 17. One end of the clamping hook 17 is wedge-shaped, facing the end of the puncture head 11, and the other end is placed on one end of a movable plate 18. A desiccant block is pressed on the other end of the movable plate 18. A telescopic spring 19 is provided between the bottom of the desiccant block and the surface of the movable plate 18. The back of the movable plate 18 is connected to a positioning plate through a torsion spring, and the positioning plate is connected to the bottom of the can body.
