[0024] Please refer to Figures 1 to 4 as shown, which shows the specific structure of the preferred embodiment of the present utility model, and is an exhaust column removal fixture.

[0025] After the exhaust column 33 on the workpiece 30 extends into the first cutting opening 11, the cutting handle 22 can dial the exhaust column 33 onto the blade 13, and the blade 13 can cut all or multiple exhaust columns 33 at one time, with higher work efficiency, good neatness, and no problem of missed cutting.

[0026] The present application provides an exhaust column removal fixture, including an upper cover 10 and a lower cover 20. The upper cover 10 is provided with a first cutting opening 11, the lower cover 20 is provided with a second cutting opening 21, and the first cutting opening 11 and the second cutting opening 21 are communicated; a blade 13 is provided on the first cutting opening 11; the cutting handle 22 is rotatably arranged on the lower cover 20; the exhaust column 33 on the workpiece 30 extends into the first cutting opening 11, and the cutting handle 22 can dial the exhaust column 33 onto the blade 13 for cutting. The upper cover 10 and the lower cover 20 are assembled together by one of the ways of screws 28, pins, snap connections, and welding. In this embodiment, the upper cover 10 and the lower cover 20 are assembled together by screws 28. During cutting, the worker places the workpiece 30 on the top of the upper cover 10 for positioning, and the exhaust column 33 on the workpiece 30 extends into the first cutting opening 11. Then the worker swings the cutting handle 22, and the cutting handle 22 can dial the exhaust column 33 onto the blade 13 for cutting. The first cutting opening 11 and the second cutting opening 21 in this embodiment are opposite, and the exhaust column 33 will fall from the second cutting opening 21 after being cut. When the cutting handle 22 acts, it can cut all or multiple exhaust columns 33 at one time, with high work efficiency, good cutting neatness, and no problem of missed cutting.

[0027] Preferably, the upper cover 10 is provided with a first installation groove 12, and the blade 13 and the fixing block 14 are embedded in the first installation groove 12. The first installation groove 12 of this embodiment is provided at the bottom of the upper cover 10. During assembly, the blade 13 and the fixing block 14 are sequentially inserted into the first installation groove 12, and the fixing block 14 presses the blade 13 against the first installation groove 12. The wall thickness between the blade 13 and the top of the upper cover 10 is less than 0.2 mm, and the thickness of the blade 13 is less than 0.1 mm. This design enables the blade 13 to fully fit the root of the exhaust column 33, and the cutting position is at the root of the exhaust column 33, resulting in good cutting quality and high neatness. Preferably, the first cutting openings 11 and the second cutting openings 21 are not less than two, and the thicknesses of each fixing block 14 are the same or different. In this embodiment, there are two first cutting openings 11 and two second cutting openings 21, and a blade 13 is provided at the position of each first cutting opening 11. One operation of the cutting handle 22 can cut off all the exhaust columns 33, and the number of cuttings can be selected. The purpose of each fixing block 14 being different is to cut the exhaust columns 33 at different positions, so as to meet the requirements of different workpieces 30, enabling the exhaust columns 33 to be completely cut at the root or cut with a certain length reserved, and the applicability is very strong. And the exhaust columns 33 with a reserved length can provide a positioning and installation function for the workpiece 30.

[0028] Preferably, the fixing block 14 is provided with an avoidance opening 15, and the cutting handle 22 has a limit block 23, and the limit block 23 can be blocked by the avoidance opening 15. The limit block 23 protrudes from the cutting handle 22. During cutting, the limit block 23 is inserted into the avoidance opening 15, and then the blade 13 can completely cut off the exhaust column 33.

[0029] Preferably, the structures of the first cutting openings 11 and the second cutting openings 21 are arc-shaped or linear. In this embodiment, the first cutting openings 11 and the second cutting openings 21 are arc-shaped. The cutting handle 22 toggles the exhaust column 33 to swing in the first cutting opening 11. When the exhaust column 33 is toggled to the first cutting opening 11 by the cutting handle 22, the blade 13 cuts off the exhaust column 33.

[0030] Preferably, a rotating shaft 24 is passed through between the upper cover 10 and the lower cover 20; the lower cover 20 is provided with a sector-shaped groove 26 and a second installation groove 27 that communicate with each other; the installation ring of the cutting handle 22 is rotatably arranged in the second installation groove 27, and the cutting handle 22 can swing in the sector-shaped groove 26; the rotating shaft 24 passes through the installation ring, and the limit pin 25 on the rotating shaft 24 is embedded in the second installation groove 27. The rotating shaft 24 can provide an installation function for the cutting handle 22, and the cutting handle 22 can rotate on the rotating shaft 24. The bottom wall of the second installation groove 27 is provided with a pin groove for fixing the limit pin 25. The limit pin 25 passes through the rotating shaft 24 and is embedded in the pin groove, so that the limit pin 25 will not come off. When the cutting handle 22 swings towards the blade 13 in the sector-shaped groove 26, the exhaust column 33 is pressed against the blade 13 by the cutting handle 22, and then the exhaust column 33 is cut off.

[0031] Preferably, the top of the upper cover 10 is provided with a first positioning post 17 and a second positioning hole 18; the first positioning post 17 penetrates into the first positioning hole 32 on the workpiece 30, and the second positioning post 31 on the workpiece 30 is inserted into the second positioning hole 18. The first positioning post 17 and the second positioning hole 18 can be used for positioning the workpiece 30. In this embodiment, the first positioning post 17 is cylindrical and the second positioning hole 18 is arc-shaped. The first positioning hole 32 is a round hole, and the second positioning post 31 is an arc-shaped hole. In this way, the workpiece 30 can rotate on the upper cover 10, and it is very convenient and efficient for the blade 13 to cut the exhaust column 33.

[0032] The preferred assembly steps of the exhaust column 33 removing fixture are as follows: 1. The limit pin 25 is passed through the rotating shaft 24, and then the rotating shaft 24 is assembled in the second installation groove 27. 2. The blade 13 and the fixing block 14 are embedded in the first installation groove 12 of the upper cover 10. 3. The cutting handle 22 is passed through the rotating shaft 24. 4. The upper cover 10 and the lower cover 20 are locked together with screws 28. It can be seen that the exhaust column 33 removing fixture has a simple structure, is convenient to assemble and use.

[0033] A disassembly hole 16 penetrates through the groove wall of the first installation groove 12, and the fixing block 14 is exposed at this disassembly hole. When replacing the blade 13, use a small rod to poke the disassembly hole 16, and it is very convenient for the fixing block 14 and the blade 13 to exit from the first installation groove.

[0034] In summary, the design focus of the present utility model is that a blade 13 is provided on the first cutting opening 11, the first cutting opening 11 and the second cutting opening 21 communicate with each other, and the cutting handle 22 is rotatably arranged on the lower cover 20. Therefore, when the workpiece 30 is placed on the upper cover 10, the exhaust column 33 on the workpiece 30 extends into the first cutting opening 11, and by swinging the cutting handle 22, the exhaust column 33 can be toggled to the blade 13 to be cut off. The fixture can cut off multiple or all exhaust columns 33 at one time, with high working efficiency. At the same time, the trimming neatness of this fixture is good, and there is no problem of missed cutting.
