[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In order to solve the problem that multiple bolts need to be removed to replace the tool, the replacement process is cumbersome, takes a lot of time, and seriously affects the work efficiency, please refer to Figure 1-4 , this embodiment provides the following technical solutions:
[0022] A disc blade that is easy to replace quickly includes a mounting handle 1 and a blade body 2. A fixing seat 11 is provided on the mounting handle 1, and one side of the fixing seat 11 abuts against the blade body 2. A limiting ring 12 is installed on one side of the blade body 2, and one side of the limiting ring 12 abuts against a fixing ring 13. The diameter of one side of the mounting handle 1 is smaller than the diameter of the other side. The limiting ring 12 and the fixing ring 13 are sleeved with the mounting handle 1, and the inner ring diameter of the fixing ring 13 is larger than the diameter of one side of the mounting handle 1. One side of the mounting handle 1 is fixedly connected to a fixing column 14 by bolts, and one side of the fixing ring 13 is meshed with the fixing column 14 by fixing bolts 16.
[0023] In this embodiment, the fixing seat 11 is tightly abutted against one side of the blade body 2, and the limiting ring 12 is installed to the other side of the blade body 2 so that one side of the limiting ring 12 abuts against the fixing ring 13, and the thicker side of the mounting handle 1 is fixedly connected to the fixing column 14. When the fixing ring 13 slides to a suitable position so that it fits tightly with the blade body 2, the fixing bolt 16 is tightened to engage with the fixing column 14, thereby fixing the fixing ring 13 and the blade body 2 on the mounting handle 1. The overall structure is simple. The blade body 2 can be quickly and easily installed and disassembled through simple socketing and bolt fixing, which greatly reduces the time and labor required for replacing the blade.
[0024] In this embodiment, the surfaces of the fixing seat 11 and the limiting ring 12 are respectively provided with evenly distributed anti-slip grooves 15, one side of the fixing seat 11 is fixedly connected to the fixing column 14, the surface of the fixing column 14 is provided with a threaded hole 17 adapted to the fixing bolt 16, the fixing bolt 16 is engaged with the fixing ring 13, one side of the limiting ring 12 is provided with a tension ring piece 18, one side of the fixing seat 11 is provided with an embedding groove 19 adapted to the tension ring piece 18, and the inner side of the tension ring piece 18 is set to a ring shape that fits the mounting handle 1.
[0025] In this embodiment, the anti-slip grooves 15 arranged on the surfaces of the fixing seat 11 and the limiting ring 12 increase the friction between the blade body 2 and the components to prevent the blade from loosening or falling off due to vibration or impact force during the use of the blade. The tension ring 18 further enhances the fixing effect of the blade body 2. When the blade body 2 is installed in place, the tension ring 18 is connected to the fixing seat 11 through the embedding groove 19, and a certain pressure is applied to the mounting handle 1 to ensure that the blade body 2 is not easy to loosen, thereby ensuring the stability and firmness of the blade body 2 on the mounting handle 1, reducing the risk of the blade falling off or loosening during operation, adapting to a variety of different application scenarios and cutting requirements, and improving its versatility and practicality.
[0026] In this embodiment, the blade body 2 includes a cutter disc 21 and an outer ring cutter head 22. The cutter disc 21 and the outer ring cutter head 22 are connected as a whole. The cross-section of the outer ring cutter head 22 is an inclined slope. A groove matching the tension ring sheet 18 is provided at the center of the cutter disc 21. A positioning port is provided on one side of the groove, and the positioning port is nested and connected with the fixing column 14.
[0027] In this embodiment, the design of the anti-slip groove 15 and the tension ring 18 increases the friction between the blade and the mounting handle, reducing the risk of injury due to accidents. It is suitable for various types of disc blades, and different blade bodies 2 can be replaced according to different processing requirements. The cross-section of the outer ring cutter head 22 is an inclined slope, making it suitable for various cutting tasks, and has a better cutting angle and efficiency during cutting. It is connected to the fixing column 14 through the positioning port, ensuring that the blade body 2 has the correct position and direction after installation, while preventing the blade body 2 from rotating on the mounting handle 1, ensuring that the blade can rotate and cut stably.
[0028] Working principle: When it is necessary to install or replace the blade, first ensure that the fixing seat 11 on the mounting handle 1 is tightly abutted against one side of the blade body 2, and then, install the limiting ring 12 to the other side of the blade body 2 so that one side of the limiting ring 12 is abutted against the fixing ring 13. Since the diameter of one side of the mounting handle 1 is smaller than the other side, the limiting ring 12 and the fixing ring 13 can be easily sleeved on the mounting handle 1, and the inner ring diameter of the fixing ring 13 is larger than the thinner side of the mounting handle 1, so that the fixing ring 13 can slide on the mounting handle 1, and the inner wall of the tension ring 18 is tightly fitted with the mounting handle 1, and the outer wall of the tension ring 18 is abutted against the blade body 2, thereby ensuring the stability of the blade body 2.
[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
