[0036] Working principle: When in use, the user drives the transmission box 4 and the flame retardant filter bag body 2 to move downward through the handle 21. During the downward movement of the transmission box 4, the sleeve 5 pushes the triangular clamping plate 10 inside the transmission box 4 to move toward the side close to the flame retardant filter bag body 2, and at the same time, the triangular clamping plate 10 compresses the spring piece 12 through the slide plate 9. After the flame retardant filter bag body 2 moves to the appropriate position, the spring piece 12 pushes the triangular clamping plate 10 to be clamped into the interior of the clamping sleeve 5 through its own elastic force. When the flame retardant filter bag body 2 needs to be removed, the user presses the L-shaped plate 13 downward, and the L-shaped plate 13 pushes the triangular rotating plate 7 and the transmission rod 8 to rotate around the pin rod 6. The transmission rod 8 pushes the triangular clamping plate 10 to move toward the side away from the clamping sleeve 5 through the concave plate 11 and the slide plate 9. At the same time, the concave plate 11 limits the spring piece 12. After the slide plate 9 moves to the appropriate position, the triangular clamping plate 10 is separated from the clamping sleeve 5, and the user removes the flame retardant filter bag body 2.
