[0044] The cross bar 21 is screwed on both sides of the exhaust duct 11, the card slot 22 is opened on the outer side surface of the cross bar 21, the slider 23 is slidably connected inside the card slot 22, the connecting seat 24 is fixed to the outer side end of the slider 23, the connecting rod 25 is rotatably connected inside the outer side end of the connecting seat 24, and the cutting block 27 is located above the connection part of the exhaust ducts 11;

[0045] The cross bar 21 is used for connecting other components such as the card slot 22 and the slider 23. The cross bar 21 is screwed to the exhaust duct 11 for easy loading and unloading of the cross bar 21. The card slot 22 is used for the connection and sliding of the slider 23. The slider 23 is used for the connection of the connecting seat 24. The connecting seat 24 is used for the connection and rotation of the connecting rod 25. The connecting rod 25 is used for the connection of the cutting block 27 and the extension rod 26. The cutting block 27 cuts and separates the connection part of the exhaust duct 11 and the rubber strip 12;

[0046] The top end of the cutting block 27 is fixedly connected with an extension rod 26, and a vertical groove 28 is opened inside the top end of the connecting rod 25;

[0047] The cross bars 21 are placed crosswise on both sides of the exhaust ducts 11;

[0048] The extension rod 26 is used for the connection between the cutting block 27 and the connecting rod 25. The vertical groove 28 is used for the placement and operation of the spring 29. The cross bar 21 is located above and below one side of the exhaust duct 11 and on the left and right sides of the other side of the exhaust duct 11.

[0053] The installation guiding component further includes a locking column 43. The locking column 43 is threaded into the middle of the connected and opposite guiding tubes 42.

[0054] The locking column 43 and the guiding tube 42 are used in cooperation to structurally install and fix the adjacent exhaust ducts 11 that are aligned and guided.

[0055] Working principle:

[0056] During use, rotate the connecting rod 25 by hand, so that the connecting rod 25 rotates through the connecting seat 24, prompting the connecting rod 25 to drive the cutting block 27 to rotate above the connection between the exhaust duct 11 and the rubber strip 12. Then press the extension rod 26 by hand. At this time, the spring 29 contracts, and the extension rod 26 enters the vertical groove 28 through the spring 29, causing the extension rod 26 to drive the cutting block 27 to cut into the connection between the exhaust duct 11 and the rubber strip 12.

[0057] Then push the connecting rod 25, so that the slider 23 moves in the card slot 22, thereby enabling the connecting rod 25 to drive the cutting block 27 to move through the slider 23. During the movement of the cutting block 27, the connection between the exhaust duct 11 and the rubber strip 12 is cut.

[0058] In the above steps, through the interaction between the slider 23 and the card slot 22, the cutting block 27 is driven to move.

[0059] Please refer toFigures 1 - 2 , Figures 5 - 6 As shown in Figures 5 - 6 , based on the above-mentioned Embodiment 1, this embodiment further includes:

[0060] A limiting component;

[0061] The limiting component includes a fixing block 31, a mounting rod 32, and an annular block 33;

[0062] The fixing block 31 is fixed to one side of the flange surface of the exhaust duct 11. The mounting rod 32 is threadedly connected to the inside of the outer end of the fixing block 31. The annular block 33 is fixed to the outer end of the mounting rod 32;

The mounting rod 32 is used for the connection between the annular block 33 and the fixing block 31. The annular block 33 is used for limiting the connecting rod 25. The annular block 33 is a PVC board and has toughness;

[0064] A notch 35 is opened on one side of the annular block 33. A friction pad 34 is fixedly connected inside the annular block 33;

[0065] The notch 35 is used for the connecting rod 25 to enter the inner side of the annular block 33. The friction pad 34 can increase the friction force between the connecting rod 25 and the annular block 33, so as to better limit the connecting rod 25;

[0066] Working principle:

[0067] When the cutting block 27 is not in use, push the connecting rod 25 so that the connecting rod 25 moves to the notch 35 of the annular block 33 through the slider 23. Then continue to push the connecting rod 25. Since the annular block 33 is a PVC board and has toughness, when the connecting rod 25 enters the annular block 33, the force of the connecting rod 25 moving squeezes the notch 35, causing the annular block 33 to expand outwards, so that the connecting rod 25 enters the annular block 33. At the same time, the annular block 33 limits the connecting rod 25, and the friction pad 34 increases the friction force between the connecting rod 25 and the annular block 33, so as to better limit the cutting block 27 and the connecting rod 25;

[0068] The above steps can improve its own functionality.
