[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 -5, the present invention provides a technical solution: a linear cutting stapler with a replaceable cutting module, including a linear cutting stapler main body 1, and an installation mechanism 2 is arranged on the linear cutting stapler main body 1.

[0024] The installation mechanism 2 includes an installation ring 21, a chute 22, a fixing groove 23, a fixing hole 24, a first spring 25, a limiting block 26, a connecting plate 27, an adjusting ring 28 and a fixing block 29. An installation ring 21 is fixed to the outer wall of the linear cutting stapler body 1. A chute 22 is provided on the inner wall of the installation ring 21. A fixing groove 23 is provided on the inner wall of the chute 22. A fixing hole 24 is provided on the outer wall of the installation ring 21, and the fixing hole 24 is connected to the chute 22. A first spring 25 is installed inside the fixing hole 24. A limiting block 26 is installed at one end of the first spring 25. A connecting plate 27 is fixed to the outer wall of the limiting block 26. An adjusting ring 28 is fixed to the outer wall of the connecting plate 27. A fixing block 29 is fixed to the outer wall of the linear cutting stapler body 1. Through the settings of the installation ring 21, the chute 22, the fixing groove 23, the fixing hole 24, the first spring 25, the limiting block 26, the connecting plate 27, the adjusting ring 28 and the fixing block 29, during use, the installation ring 21 is fixed at the connection between the machine body 11 and the connecting column 13. Then, the first spring 25 is installed in the fixing hole 24 provided on the outer wall of the installation ring 21. The limiting block 26 is installed in the chute 22, and one end of the limiting block 26 is connected to the first spring 25. The connecting plate 27 is installed outside the limiting block 26 and is connected to the inner wall of the adjusting ring 28 through the fixing hole 24. When installing the cutting module 14, the fixing block 29 at the bottom of the connecting column 13 fixed with the cutting module 14 is aligned with the chute 22 and inserted. At this time, the fixing block 29 squeezes the limiting block 26 inward so that it contracts into the fixing hole 24. Then, the connecting column 13 is rotated, and the fixing block 29 at the bottom of the connecting column 13 will snap into the fixing groove 23. At this time, the limiting block 26 will be ejected by the first spring 25 and snap into the chute 22, so that the fixing block 29 is fixed in the fixing groove 23. When the cutting module 14 needs to be replaced, the adjusting ring 28 is pulled backward. At this time, the adjusting ring 28 drives the limiting block 26 through the connecting plate 27 to compress the first spring 25 inward. At this time, the limiting block 26 will slide out of the chute 22. Then, the connecting column 13 is rotated so that the fixing block 29 slides out of the fixing groove 23. At this time, the cutting module 14 can be replaced.

[0025] Furthermore, the linear cutting stapler body 1 includes a machine body 11, a handle 12, a connecting column 13 and a cutting module 14. A handle 12 is provided on the outer wall of the machine body 11. A connecting column 13 is installed on the outer wall of the machine body 11. A cutting module 14 is installed at one end of the connecting column 13. Through the settings of the machine body 11, the handle 12, the connecting column 13 and the cutting module 14, during use, the handle 12 is installed on the bottom wall of the machine body 11, and the cutting module 14 is connected to the machine body 11 through the connecting column 13.

[0026] Furthermore, a fixing component 3 is provided on the outer wall of the linear cutting stapler body 1. The fixing component 3 includes a fixing shell 31, a mounting hole 32, an outer shell 33, a second spring 34, a bolt 35, a connecting shaft 36, a cover plate 37, and a limiting groove 38. A fixing shell 31 is fixed to the outer wall of the mounting ring 21. A mounting hole 32 is provided on the fixing shell 31. An outer shell 33 is provided on the outer wall of the mounting hole 32. A second spring 34 is fixed to the inner wall of the outer shell 33. A bolt 35 is installed inside the mounting hole 32. A connecting shaft 36 is fixed to the outer wall of the mounting ring 21. A cover plate 37 is provided on the outer wall of the connecting shaft 36. A limiting groove 38 is provided on the bottom wall of the cover plate 37. Through the settings of the fixing shell 31, the mounting hole 32, the outer shell 33, the second spring 34, the bolt 35, the connecting shaft 36, the cover plate 37, and the limiting groove 38, when in use, when the connecting column 13 is installed into the mounting ring 21, the cover plate 37 is buckled downward through the connecting shaft 36, so that the bolt 35 is snapped into the limiting groove 38. At this time, the outer wall of the connecting column 13 will be fixed by the fixing shell 31 and the cover plate 37, which can prevent it from shaking during use. When the cutting module 14 needs to be replaced, the bolt 35 is toggled so that the bolt 35 is withdrawn from the limiting groove 38, and then the cover plate 37 is flipped upward. At this time, the connecting column 13 fixed with the cutting module 14 can be taken out for replacement.

[0027] Furthermore, the sliding grooves 22 are symmetrically provided with respect to the central axis of the mounting ring 21. The inner wall size of the sliding grooves 22 matches the outer wall size of the fixing blocks 29. Through the setting of the fixing blocks 29, when in use, the fixing blocks 29 and the fixing grooves 23 are used in cooperation to fix the connecting column 13 inside the mounting ring 21.

[0028] Furthermore, the inner wall size of the adjusting ring 28 matches the outer wall size of the mounting ring 21. The connecting plates 27 are symmetrically installed with respect to the central axis of the adjusting ring 28. Through the setting of the adjusting ring 28, when in use, when the cutting module 14 needs to be replaced, the adjusting ring 28 is pulled backward. At this time, the adjusting ring 28 drives the limiting blocks 26 to compress the first spring 25 inward through the connecting plates 27. At this time, the limiting blocks 26 will slide out of the sliding grooves 22, and then the connecting column 13 is rotated. At this time, the fixing blocks 29 can slide out of the fixing grooves 23.

[0029] Furthermore, the inner wall size of the sliding grooves 22 matches the outer wall size of the limiting blocks 26, and the outer wall size of the fixing blocks 29 matches the inner wall size of the fixing grooves 23. Through the setting of the limiting blocks 26, when in use, when the fixing blocks 29 are snapped into the fixing grooves 23, the limiting blocks 26 will be snapped into the sliding grooves 22, so that the fixing blocks 29 are fixed in the fixing grooves 23.

[0030] Furthermore, one end of the second spring 34 is connected to the outer shell 33, and the other end of the second spring 34 is connected to the bolt 35. Through the setting of the second spring 34, when in use, the second spring 34 will keep the bolt 35 in a protruding state all the time.

[0031] Working principle: When in use, fix the mounting ring 21 at the connection between the machine body 11 and the connecting column 13. Then install the first spring 25 in the fixing hole 24 opened on the outer wall of the mounting ring 21, install the limiting block 26 in the sliding groove 22, and make one end of the limiting block 26 connected to the first spring 25. Install the connecting plate 27 outside the limiting block 26 and connect it to the inner wall of the adjusting ring 28 through the fixing hole 24. When installing the cutting module 14, align the fixing block 29 at the bottom of the connecting column 13 with the cutting module 14 and insert it into the sliding groove 22. At this time, the fixing block 29 will squeeze the limiting block 26 inward so that it contracts into the fixing hole 24. Then rotate the connecting column 13, and the fixing block 29 at the bottom of the connecting column 13 will snap into the fixing groove 23. At this time, the limiting block 26 will be ejected by the first spring 25 and snap into the sliding groove 22, so that the fixing block 29 is fixed in the fixing groove 23. When it is necessary to replace the cutting module 14, pull the adjusting ring 28 backward. At this time, the adjusting ring 28 drives the limiting block 26 through the connecting plate 27 to compress the first spring 25 inward. At this time, the limiting block 26 will slide out of the sliding groove 22. Then rotate the connecting column 13 so that the fixing block 29 slides out of the fixing groove 23. At this time, the cutting module 14 can be replaced. When the connecting column 13 is installed in the mounting ring 21, buckle the cover plate 37 downward through the connecting shaft 36 so that the bolt 35 snaps into the limiting groove 38. At this time, the outer wall of the connecting column 13 will be fixed by the fixed shell 31 and the cover plate 37, which can prevent it from shaking during use. When it is necessary to replace the cutting module 14, toggle the bolt 35 so that the bolt 35 is pulled out of the limiting groove 38, and then flip the cover plate 37 upward. At this time, the connecting column 13 fixed with the cutting module 14 can be taken out for replacement.
