[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a replaceable cutting blade mounting structure includes a blade holder 1 and a blade 2 installed inside the blade holder 1. A through hole 3 is provided in the middle of the blade holder 1, and first mounting holes 4 are provided at equal intervals in the middle of the blade 2. A second mounting hole 5 is provided at the bottom end of the blade holder 1 corresponding to the position of the first mounting hole 4 on the blade 2. The second mounting hole 5 penetrates the entire blade holder 1. A positioning rod 6 is slidably installed inside the first mounting hole 4 and the second mounting hole 5. A first spring 7 is sleeved on the outer side of one end of the positioning rod 6. One end of the first spring 7 is fixedly connected to one end of the positioning rod 6, and the other end of the first spring 7 is fixedly connected to one side of the blade holder 1. A pull plate 8 is fixedly installed between the end of the positioning rod 6 and the end near the first spring 7. When replacing the old blade 2, pull the pull plate 8 to slide the positioning rod 6 out of the first mounting hole 4. At this time, the first spring 7 is in the extended state, and the blade 2 can be directly taken out from the top of the through hole 3 in the middle of the blade holder 1 without disassembling the entire blade holder 1, which facilitates the disassembly of the blade 2. The new blade 2 is slid into the top of the through hole 3 in the middle of the blade holder 1. When the bottom of the new blade 2 moves to the installation position, it will drive the positioning rod 6 to slide into the first mounting hole 4 and the second mounting hole 5 at the same time, which can fix the position of the new blade 2 and facilitate the installation of the blade 2.

[0022] like Figures 1 to 5As shown, a fixing rod 9 is fixedly installed at the rear center of the tool holder 1. A rotating plate 10 is slidably and rotatably installed on the outer side of the fixing rod 9. A first support rod 11 is fixedly installed on one side of the bottom end of the rotating plate 10. The first support rod 11 is positioned below the blade 2. An insertion rod 12 is fixedly installed on one side of the rotating plate 10. A top insertion hole 13 and a bottom insertion hole 14 are respectively opened at the top and bottom ends of the rotation trajectory of the insertion rod 12 at the rear of the tool holder 1. The insertion rod 12 is slidably inserted into the top insertion hole 13 and the bottom insertion hole 14. A second spring 15 is sleeved on the outer side of the fixed rod 9 away from the tool holder 1. One end of the second spring 15 is fixedly connected to one end of the fixed rod 9, and the other end of the second spring 15 is in contact with one side of the rotating plate 10.

[0023] When replacing the old blade 2, slide the rotating plate 10 along the trajectory of the fixing rod 9 to slide the insertion rod 12 out of the top insertion hole 13. At this time, the second spring 15 is in a compressed state. Then rotate the rotating plate 10 180 degrees to move the first support rod 11 at the bottom of the rotating plate 10 to the bottom of the blade 2. The first support rod 11 is used to support the blade 2. Then, the second spring 15 pushes the rotating plate 10 to drive the insertion rod 12 into the bottom insertion hole 14 to fix the position of the rotating plate 10. After the blade 2 is disassembled, slide the new blade 2 into the top of the through hole 3 in the middle of the blade holder 1. When the bottom of the new blade 2 moves to the installation position of the blade 2, the bottom of the new blade 2 will contact the first support rod 11, which can support the blade 2 during installation and disassembly, and facilitate the support and positioning of the blade 2 during installation and disassembly.

[0024] like Figures 1 to 5 As shown, the tool holder 1 has symmetrical sliding holes 16 at the front. A second support rod 17 is slidably installed inside the sliding hole 16. A third spring 18 is sleeved on the outer side of one end of the second support rod 17. One end of the third spring 18 is fixedly connected to one end of the second support rod 17, and the other end of the third spring 18 is fixedly connected to one side of the tool holder 1.

[0025] The new blade 2 is slid into the top of the through hole 3 in the middle of the tool holder 1, and the bottom of the new blade 2 is supported by the second support rod 17, which facilitates the support and positioning of the blade 2 when it enters the through hole 3.

[0026] like Figures 1 to 5As shown, the front center of the tool holder 1 is open, and a sliding groove 19 is provided in the front center of the tool holder 1. A lifting block 20 is slidably installed inside the sliding groove 19. Limiting holes 21 are symmetrically provided in the center of the lifting block 20. U-shaped rods 22 are slidably installed inside the two limiting holes 21. An installation plate 23 is fixedly installed at the end of the U-shaped rod 22. A rubber pad 24 is fixedly installed on one side of the installation plate 23. A fourth spring 25 is symmetrically sleeved on the outside of the U-shaped rod 22. One end of the fourth spring 25 is fixedly connected to one side of the lifting block 20, and the other end of the fourth spring 25 is fixedly connected to the outside of the U-shaped rod 22.

[0027] Hold and push the U-shaped rod 22 to slide between the two limiting holes 21. At this time, the fourth spring 25 is in a compressed state, controlling the rubber pad 24 to squeeze the new blade 2. The new blade 2 is controlled by the squeezing friction between the rubber pad 24 and the new blade 2. Then, the lifting block 20 descends along the trajectory of the slide groove 19, gradually lowering the new blade 2 that is in contact with the squeezing rubber pad 24, which facilitates the movement of the blade 2 during the installation process.

[0028] This utility model provides a cutter mounting structure that is easy to replace, and its working principle is as follows:

[0029] When the device is in use, when replacing the old blade 2, slide the rotating plate 10 along the trajectory of the fixing rod 9 to slide the insertion rod 12 out of the top insertion hole 13. At this time, the second spring 15 is in a compressed state. Then rotate the rotating plate 10 180 degrees to move the first support rod 11 at the bottom of the rotating plate 10 to the bottom of the blade 2. The first support rod 11 is used to support the blade 2. Then, the second spring 15 pushes the rotating plate 10 to drive the insertion rod 12 into the bottom insertion hole 14 to fix the position of the rotating plate 10. Then pull the pull plate 8 to slide the positioning rod 6 out of the first mounting hole 4. At this time, the first spring 7 is in a stretched state and at the same time pulls the second support rod 17, causing the end of the second support rod 17 to slide out of the through hole 3, canceling the positioning of the top of the blade 2 by the second support rod 17. At this time, the third spring 18 is in a stretched state, and people can directly take out the blade 2 from the top of the through hole 3 in the middle of the blade holder 1, which is convenient for disassembling the blade 2.

[0030] Slide the new blade 2 into the top of the through hole 3 in the middle of the tool holder 1. Support the bottom of the new blade 2 with the second support rod 17. Then, hold and push the U-shaped rod 22 to slide between the two limiting holes 21. At this time, the fourth spring 25 is in a compressed state, controlling the rubber pad 24 to squeeze the new blade 2. The new blade 2 is controlled by the squeezing friction between the rubber pad 24 and the new blade 2. Then, pull the second support rod 17 to drive the end of the second support rod 17 out of the through hole 3, canceling the positioning of the bottom of the blade 2 by the second support rod 17. Then, pull the pull plate 8 to store the end of the positioning rod 6 in the second mounting hole 5. At this time, the first spring 7 is in a stretched state and then slides down along the trajectory of the slide groove 19. The lowering block 20 gradually lowers the new blade 2, which is in contact with the rubber pad 24. When the bottom of the new blade 2 contacts the first support rod 11, the pull plate 8 is released, which will drive the positioning rod 6 to slide into the first mounting hole 4 and the second mounting hole 5 at the same time, thus fixing the position of the new blade 2. Then, the rotating plate 10 slides along the trajectory of the fixing rod 9, and the insertion rod 12 slides out of the bottom insertion hole 14. At this time, the second spring 15 is in a compressed state. Then, the rotating plate 10 is rotated 180 degrees, and the first support rod 11 at the bottom of the rotating plate 10 is moved to the top of the blade holder 1. Then, the second spring 15 pushes the rotating plate 10 to drive the insertion rod 12 into the top insertion hole 13 to fix the position of the rotating plate 10.
