[0001] The utility model relates to the technical field of diamond micro-cutting knives, in particular to a diamond micro-cutting knives which are easy to disassemble. Background Art

[0002] The diamond micro-cutting knife is a tool designed for fine cutting. It combines the hardness of diamond with an easy-to-operate disassembly design, allowing the user to easily disassemble and clean the knife after completing the work. The main feature of this diamond micro-cutting knife is its unique blade structure. The blade is made of high-quality diamond material with excellent hardness and wear resistance, and can easily cope with various fine cutting tasks. At the same time, the edge of the blade is precisely processed to ensure the accuracy and smoothness of the cutting.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 The utility model provides a diamond micro-cutting knife that is easy to disassemble, including a fixed seat 1, an inner wall of the fixed seat 1 is slidably connected with an adjusting rod 2, the inner wall of the adjusting rod 2 is detachably connected with a rotating shaft 3, a quick release mechanism 4 is arranged on the adjusting rod 2, the quick release mechanism 4 includes a synchronous shaft 41, the inner wall of the adjusting rod 2 is rotatably connected with the synchronous shaft 41, the outer wall of the synchronous shaft 41 is threadedly connected with a gear 42, and the outer wall of the adjusting rod 2 is slidably connected with a movable block 43.

[0027] The outer wall of the adjusting rod 2 is fixedly connected with a guide rail 5, and the outer wall of the guide rail 5 is slidably connected with a movable block 43. The movable block 43 is guided by the guide rail 5 so that the movable block 43 can only move linearly on the outer wall of the adjusting rod 2. A notch is provided on the movable block 43, and a limiting tooth 44 is provided on the inner wall of the notch. A gear 42 is slidably connected on the inner wall of the notch. By making the limiting tooth 44 clamped on the gear 42, the gear 42 is fixed, and then the synchronous shaft 41 is fixed. A rotating groove is provided on the adjusting rod 2, and the rotating groove is detachably connected with a rotating shaft 3. The outer wall of the rotating shaft 3 is fixedly connected with a placing block 6. The rotating shaft 3 can rotate on the inner wall of the rotating groove and can also slide, so as to facilitate the disassembly of the rotating shaft 3. When the limiting tooth 44 limits the gear 42, the synchronous shaft 41 is also limited, so that the placing block 6 is limited.

[0028] Furthermore, the outer wall of the guide rail 5 is fixedly connected to a fixed block 45, and a compression spring 46 is welded to the outer wall of the fixed block 45. The end of the compression spring 46 away from the fixed block 45 is welded to the outer wall of the movable block 43. The movable block 43 is squeezed by the compression spring 46 to make the movable block 43 close to the gear 42, ensuring the limiting state of the gear 42 by the limiting tooth 44. The outer wall of the placement block 6 is slidably connected to the diamond blade 7, and the outer wall of the placement block 6 is fixedly connected to the stop block 8. The placement block 6 is square, and a square through groove is opened on the diamond blade 7. The sliding range of the diamond blade 7 is limited by the stop block 8.

[0029] A storage groove is provided on the placement block 6, and a sliding plate 9 is slidably connected to the inner wall of the storage groove. A threaded rod 10 is threadedly connected to the inner wall of the sliding plate 9. The threaded rod 10 is passed through the sliding plate 9 and is in close contact with the surface of the diamond blade 7 to fix the diamond blade 7. The distance between the sliding plate and the stop block is the maximum thickness of the blade that can be installed. The device can also be used to install blades of different thicknesses, thereby improving the adaptability of the device. By loosening the threaded rod 10, the sliding plate 9 can be returned to the storage groove, and then the diamond blade 7 can slide out of the placement block 6. The outer wall of the fixed seat 1 is fixedly connected to a handle 11, and the inner wall of the fixed seat 1 is threadedly connected to an adjusting screw 12. The handle is convenient for the staff to hold the device. By loosening the adjusting screw 12, the adjusting rod 2 can be slid on the inner wall of the fixed seat 1, thereby changing the distance from the diamond blade 7 to the handle 11, which is convenient for avoidance work and allows it to adapt to different processing environments.

[0030] When in use, when the blade needs to be disassembled, the movable block is moved away from the gear, and then the gear is rotated while holding the rotating shaft to separate the gear from the synchronous shaft, which makes it convenient to move the placement block. By loosening the threaded rod and allowing the sliding plate to enter the storage slot, the diamond blade can be separated from the placement block, and the disassembly of the diamond blade can be completed quickly, thereby improving work efficiency.

[0031] By moving the movable block, the limited state of the gear can be released.
