[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0018] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a reinforced anti-rotation blade fixing structure of this utility model.

[0019] like Figure 1-4 As shown, this utility model discloses a reinforced anti-rotation blade fixing structure, including a fixing post 7. One end of the fixing post 7 is fixedly connected to a bolt body 2. A groove 3 is formed on the surface of the bolt body 2, and a blade 1 is clamped inside the groove 3. An internal threaded hole 17 is formed on the surface of the bolt body 2, and a locking nut 4 is sleeved inside the internal threaded hole 17. One end of the locking nut 4 passes through the blade 1. By installing the locking nut 4 and forming the groove 3, when installing the blade 1, the blade 1 can be directly placed inside the groove 3 inside the bolt body 2. Then, the locking nut 4 is sleeved on the surface of the bolt body 2 until one end of the locking nut 4 passes through the blade 1, at which point the blade 1 is fixed. Inside the bolt body 2, only the locking nut 4 needs to be installed when installing the blade 1, which reduces the number of fixing structures and greatly reduces the weight of the structure. The first positioning nut 5 is sleeved on the surface of the bolt body 2, and the bottom of the first positioning nut 5 is attached to the top of the blade 1. The second positioning nut 6 is sleeved on the surface of the bolt body 2, and the top of the second positioning nut 6 is attached to the bottom of the blade 1. By installing the first positioning nut 5 and the second positioning nut 6, the blade 1 can be positioned so that the blade 1 will not rotate, thereby further improving the stability of the blade 1 and ensuring the stable effect of the blade 1 during use.

[0020] A fastening nut 8 is installed on the surface of the fixed column 7. An external threaded sleeve 14 is fitted inside the fastening nut 8. An adhesive body 9 is fixedly connected to the bottom of the external threaded sleeve 14. By installing the adhesive body 9, it can be glued to a cylindrical carrier, such as a fishing rod or other cylinder, making the cutter head more convenient to use.

[0021] The other end of the fixing post 7 is fixedly connected to the card 10. The fastening nut 8 has a slot 15 inside, and the card 10 is sleeved inside the slot 15. By installing the card 10 and opening the slot 15, when the card 10 is sleeved inside the slot 15, it can provide a limiting effect for the fastening nut 8 and ensure the rotation effect of the fastening nut 8, so that the fastening nut 8 can be directly installed on the surface of the external thread sleeve 14 by rotation, making it more convenient to install the adhesive body 9.

[0022] The other end of the fixed post 7 is fixedly connected to the insertion rod 12. The insertion rod 12 has an insertion hole 13 on its surface and a bayonet 11 on its surface. An anti-rotation post 16 is sleeved inside the insertion hole 13. Both ends of the anti-rotation post 16 are located inside the bayonet 11. By installing the anti-rotation post 16, when installing the adhesive body 9, the anti-rotation post 16 can be inserted into the insertion hole 13 first, and both ends of the anti-rotation post 16 can be embedded into the bayonet 11. At this time, the stability between the fixed post 7 and the adhesive body 9 can be guaranteed, so that the fixed post 7 will not rotate during use, thereby ensuring the stability of the blade 1.

[0023] The first positioning nut 5 and the second positioning nut 6 are symmetrically distributed. The distribution of the first positioning nut 5 and the second positioning nut 6 can further improve the stability of the blade 1 after installation, resulting in stronger stability during use.

[0024] One side of the blade 1 is attached to the inner wall of the clamping groove 3, and the other side of the blade 1 is attached to the inner wall of the clamping groove 3. By having both sides of the blade 1 attached to the inner wall of the clamping groove 3, it can be ensured that the blade 1 will not shift left or right, thus ensuring the stability of the blade 1 during use.

[0025] The working principle of the blade fixing structure of this reinforced anti-rotation head is as follows: When using the blade 1, the adhesive body 9 is installed first. During this installation, the anti-rotation post 16 is inserted into the insertion hole 13, and both ends of the anti-rotation post 16 are embedded in the bayonet 11, ensuring stability between the fixing post 7 and the adhesive body 9. At this time, when the card 10 is sleeved inside the slot 15, it provides a limiting effect for the fastening nut 8 and ensures the rotation of the fastening nut 8, allowing the fastening nut 8 to be directly installed on the external threaded sleeve 1 by rotation. 4. At this point, the adhesive 9 will be installed, and there will be no rotation between the adhesive 9 and the fixing post 7. Then, the blade 1 can be installed. Since the bolt body 2 is fixedly connected to one end of the fixing post 7, and a groove 3 is opened on the surface of the bolt body 2, the blade 1 is engaged inside the groove 3. An internal threaded hole 17 is opened on the surface of the bolt body 2, and a locking nut 4 is fitted inside the internal threaded hole 17. One end of the locking nut 4 passes through the blade 1, and a first positioning nut 5 is fitted on the surface of the bolt body 2. At this point, the first positioning... The bottom of nut 5 is attached to the top of blade 1. A second positioning nut 6 is fitted onto the surface of bolt body 2, with the top of the second positioning nut 6 attached to the bottom of blade 1. When installing blade 1, the second positioning nut 6 should first be installed on the surface of bolt body 2 by rotation. Then, blade 1 can be placed directly inside the groove 3 inside bolt body 2. Subsequently, locking nut 4 is fitted onto the surface of bolt body 2 until one end of locking nut 4 penetrates blade 1, thus fixing blade 1 inside bolt body 2. Then, first positioning nut 5 is installed on the surface of locking nut 4 until the bottom of first positioning nut 5 is attached to the top of blade 1. At this point, fewer structures are used to fix blade 1, resulting in a lighter overall weight of blade 1, making subsequent use easier and improving mowing efficiency. Furthermore, the first positioning nut 5 and second positioning nut 6 can further improve the stability of blade 1, ensuring stable performance during use. Finally, the blade head is glued to a cylindrical support, such as a netting pole or other rod-shaped object, using adhesive 9, making the blade head more convenient to use.
