[0027] Two U-shaped mounting plates 9 are installed on the left and right sides of the frame 1, and the mounting plates 9 are used to fix and support the bolts 10. Bolts 10 are threadedly installed on the front and rear ends of the mounting plates 9, and the bolts 10 fix the frame 1. Handles 15 are installed on the front and rear sides of the extension plate 1 3 and the extension plate 2 4. By setting the mounting plates 9 and the bolts 10, the bolts 10 are fixed to the left and right sides of the frame 1 by utilizing the function of the mounting plates 9. Combined with the function of the bolts 10, it is convenient to fix the frame 1 at any time, and then it is convenient to disassemble or fix the frame 1. The structure is simple, and combined with the function of the handle 15, it is convenient to operate the extension plate 1 3 and the extension plate 2 4.

[0028] A groove is provided on the inner bottom surface of the frame 1, and two elastic folding plates 12 are installed in the groove. The elastic folding plates 12 improve the sealing of the frame 1. The top of the two elastic folding plates 12 is installed with the same fixed plate 13, and the upper surface of the fixed plate 13 is installed with magnet 11. The inner top surface of the frame 1 is installed with magnet 2 14 that attracts magnet 1 11. By arranging the elastic folding plates 12, magnet 1 11 and magnet 2 14, the elastic folding plates 12 are stored in the groove. The mutual attraction between magnet 1 11 and magnet 2 14 makes it convenient to stretch and fix the elastic folding plates 12 in the frame 1, thereby improving the sealing inside the frame 1.

[0029] The front side of the extension plate 2 4 is rotatably installed with a rotating column 16, and the rotating column 16 supports the fastening plate 17. The fastening plate 17 is installed on the rotating column 16, and the front side of the fastening plate 17 is provided with a fastening groove. The front side of the extension plate 1 3 is installed with an L-shaped plate 18 arranged in coordination with the fastening groove. By setting the fastening plate 17 and the L-shaped plate 18, and utilizing the fastening groove on the fastening plate 17 to cooperate with the L-shaped plate 18, it is convenient to fix the extension plate 1 3 and the extension plate 2 4 together.

By setting the insertion rod 20 and the spring 22, the support plate 19 is used to support the insertion rod 20 so that the insertion rod 20 can slide up and down. The combined effect of the slot can strengthen the fixation of the fastening plate 17. Combined with the elastic effect of the spring 22 and the effect of the pull plate 21, the insertion rod 20 can be assisted to quickly reset, thereby improving efficiency.

[0031] A sealing groove is provided on the side surface of the seat of the extension plate 2 4, and a sealing strip 6 is installed on the side surface of the extension plate 1 3 to cooperate with the seal. By providing the sealing strip 6 and utilizing the effect of the sealing strip 6 cooperating with the sealing groove, when the extension plate 1 3 and the extension plate 2 4 are close to each other, the sealing between the extension plate 1 3 and the extension plate 2 4 is increased, thereby improving the sealing degree of the equipment.

[0032] When in use, place the frame 1 in a suitable position, and then turn the bolts 10 to fix the frame 1. When it is necessary to close, pull the two handles 15 closer to each other, and the handles 15 respectively drive the extension plate 1 3 and the extension plate 2 4 closer to each other. When the extension plate 1 3 and the extension plate 2 4 move, the telescopic rod 8 is stretched. At this time, the extension plate 1 3 and the extension plate 2 4 gradually extend out of the accommodating frame 2. When the extension plate 1 3 and the extension plate 2 4 move, one end of the sealing card plate 7 is driven to slide in the card slot. The extension plate 1 3 drives one end of the sealing strip 6 to extend into the sealing slot. When the extension plate 1 3 and the extension plate 2 4 are in contact with each other, there is still a small part of the extension plate 1 3 and the extension plate 2 4. The parts are located in the accommodating frame 2, and then the insertion rod 20 is moved upward. The insertion rod 20 slides on the support plate 19 to stretch the spring 22 and rotate the fastening plate 17. The fastening plate 17 drives the rotating column 16 to rotate. The fastening plate 17 rotates clockwise so that a part of the L-shaped plate 18 is in the fastening groove, and then the pulling plate 21 is released. At this time, the insertion rod 20 is inserted into the slot by the reaction force of the spring 22 to fix the fastening plate 17, and then the fixing plate 13 is moved upward. The fixing plate 13 moves out of the groove to stretch the elastic folding plate 12. When magnet 1 11 and magnet 2 14 are in contact and attracted, the elastic folding plate 12 is fixed in the frame 1, thereby improving the sealing effect of the frame 1.
