[0022] Working principle: Pulling the L-shaped clamp 11 moves the slide cylinder 8. The movement of the slide cylinder 8 causes the L-shaped clamp 11 to move the first spring 9. The movement of the first spring 9 moves the L-shaped clamp 11 into the first support cylinder 12. At this time, the limiting band 2 passes through the clamp 5 and through the card box 4. After the limiting band 2 is inserted into the card box 4, the L-shaped clamp 11 is released, causing the first spring 9 to spring back. The spring 9 springs back, causing the L-shaped clamp 11 to be inserted into the first opening 3 to fix it and seal the explosion-proof bag. This achieves rapid sealing of explosion-proof bags used in airline catering carts. The high-speed operation of the F-shaped frame 16 provides support for the No. 5 spring 22. When sealing the explosion-proof bag, the rubber strip 15 is inserted into the slot 14, which moves the fixed head 19. The movement of the fixed head 19 moves the No. 1 frame 20, which in turn moves the No. 5 spring 22. The movement of the No. 1 frame 20 causes the fixed head 19 to come into close contact with the rubber strip 15, improving the sealing performance. This achieves the function of improving the sealing performance and enhancing the explosion-proof effect of the explosion-proof bag used in aviation catering carts.
