[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0022] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0023] Reference Figure 1 and Figure 2 as well as Figure 3As shown, a circular saw blade is mainly used for cutting low-hardness carbon steel and non-ferrous metal rods and pipes. In existing cutting devices, most of them are installed in a detachable connection manner. During the installation process, most of the existing circular saw blades are mostly installed by inserting the circular saw blade into a driving device and fixing it with bolts. The fixing method with bolts will affect the surface flatness of the circular saw blade, and in severe cases, it will cause the circular saw blade to fail. In order to solve this kind of problem, a plug-in circular saw blade is proposed, including a circular saw blade body 1, a first card slot 12 for being mounted on a drive shaft 21 is opened in the circular saw blade body 1, the first card slot 12 extends outward to form a plurality of second card slots 121 distributed in an array and arranged at intervals, the circular saw blade body 1 slides horizontally forward and backward along the drive shaft 21 for replacing the circular saw blade body 1, and one side of the circular saw blade body 1 is connected to the A limit piece 2 is provided between the driving shaft 21, and the limit piece 2 includes a limit groove 23 opened in the circumferential direction of the driving shaft 21, and the limit groove 23 is through-set on both sides, and a limit rod is provided on one side of the limit groove 23 to slide in or out, and the limit rod is slidably set along the side of the circular saw blade body 1; the purpose of orderly snapping into the driving shaft 21 can be achieved by setting the first card slot 12 in the circular saw blade body 1, and with the synchronous setting of the second card slot 121 and the protrusion 211 on the driving shaft 21, the purpose of ensuring that the circular saw blade body 1 can rotate in an orderly manner can be achieved, and the setting of the limit piece 2 can achieve the purpose of making the limit rod gradually penetrate into the limit groove 23, thereby achieving the purpose of fixing the circular saw blade body 1 and the driving shaft 21, and such a fixing method can avoid the problem of surface displacement and damage to the circular saw blade, thereby achieving the purpose of effectively protecting the circular saw blade body 1.

[0024] It should be noted that, in order to ensure that the limit rod can slide into or out of the limit groove 23 in an orderly manner, in this embodiment, the limit groove 23 is opened at a position passing through the axis of the drive shaft 21, and the size specifications of the limit rod and the limit groove 23 are consistent; the axis here means the limit groove 23, and the setting method thereof refers to Figure 1 As shown in , the dotted line portion can specifically indicate the arrangement of the limiting rod and the limiting groove 23.

[0025] Furthermore, in order to ensure the stability of the limit rod set on the circular saw blade body 1, in this embodiment, a protective shell for limiting the sliding of the limit rod is provided on one side surface of the circular saw blade body 1, and the protective shell and the limit rod are threadedly connected; the stability of the limit rod during the sliding process can be achieved by the setting of the protective shell, and the setting of the protective shell can ensure that the limit rod slides in or out of the limit groove 23 in an orderly manner.

[0026] In addition, the threaded connection between the protective shell and the limit rod can ensure that when the operator slides the limit rod out, the limit rod can be rotated to gradually approach the limit groove 23, ensuring that the entire fixing method is carried out in an orderly and stable manner.

[0027] It should also be noted that since the two sides of the limit groove 23 are set through, in order to avoid the above-mentioned limit rod from over-traveling during the sliding process, in this embodiment, a stop rod 32 for protecting the limit rod from sliding over-travel is respectively provided on a section of the limit rod away from the protective shell; the purpose of protecting the limit rod from over-travel can be achieved by setting the stop rod 32.

[0028] Further, see Figure 2 As shown in the figure, the entire circular saw blade body 1 rotates in unison with the rotation of the drive shaft 21, including the limiter 2. During the rotation, it is necessary to ensure the stability of the limiter 2 itself. That is to say, the circular saw blade body 1 and the limiter 2 are integrally arranged during the production process, and the material thereof can also be a material with higher strength, such as alloy.

[0029] It should be noted that the above-mentioned setting mode of the limit rod will not affect the cutting effect of the circular saw blade body 1.

[0030] It is worth mentioning that in order to ensure that the first card slot 12 and the second card slot 121 in the circular saw blade body 1 are better matched with the driving shaft 21, in this embodiment, the outer periphery of the driving shaft 21 protrudes outward to form a plurality of protrusions 211 for being inserted into the second card slot 121, and a plurality of protective pads 22 for protecting the circular saw blade body 1 are also provided between the driving shaft 21 and the first card slot 12; the setting of the protrusions 211 and the protective pads 22 can achieve the purpose of better protecting the circular saw blade body 1, and can better extend the life of the circular saw blade body 1 and its practical effect.

[0031] Additionally, a chip removal groove 11 is provided on the outer circumference of the circular saw blade body 1 for removing chips during the cutting process.

[0032] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
