[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 shown, a circular saw blade is a cutting tool installed in a circular saw machine, and is an indispensable part of the cutting process. Most of the existing circular saw blades are designed and produced in a single-piece manner, and their structure is relatively simple. When encountering workpieces with different cutting requirements, most of them need to frequently replace the circular saw blades in the circular saw machine, resulting in a decrease in the overall cutting efficiency. In addition, the circular saw blade has no protective structure during the cutting process, which can easily cause injuries to the operator. In order to solve such problems, a combined circular saw blade is proposed, including a circular saw combination 1 and a protective frame 2 for protection arranged outside the circular saw combination 1, wherein the circular saw combination 1 includes a first saw blade 11, a second saw blade 12, and a third saw blade 13 arranged in sequence, wherein the first saw blade 11, the second saw blade 12, and the third saw blade 13 are sleeved with a driving mechanism for driving the circular saw combination 1. The sleeve 112, the first saw blade 11, the second saw blade 12 and the third saw blade 13 are concentrically arranged, and the diameter lengths decrease successively to form a step shape for orderly cutting of workpieces of different specifications, the circular saw assembly 1 is placed in the protective frame 2, and a protective member 3 for preventing waste chips from splashing is also provided between the circular saw assembly 1 and the protective frame 2; a combined circular saw blade is formed by the arrangement of the circular saw assembly 1 and the protective frame 2, and it contains a plurality of circular saw blades that are concentrically arranged and have gradually decreasing diameter lengths, which can be switched conveniently and quickly when the cutting requirements are different, thereby saving the time for frequent replacement of circular saw blades, and can greatly improve the overall cutting efficiency, and the synchronous arrangement of the protective frame 2 and the protective member 3 can also achieve protection for cutting, effectively avoiding the problem of splashing waste chips causing damage to the operator.

[0024] It should be noted that the above-mentioned sleeve 112 is provided for connecting with the driving structure of an external circular saw machine. The driving structure here can be a driving shaft, and the sleeve 112 can be sequentially clamped on the outer circumference of the driving shaft. When the driving shaft rotates, the purpose of driving the entire circular saw combination 1 to rotate can be achieved. In addition, the protective frame 2 in this embodiment can also be provided with a handle on the outside for the operator to hold. The handle here is used to fix and limit the entire protective frame 2. This part of the structure is more common in existing cutting machines.

[0025] Furthermore, the specific structure of the above-mentioned protective frame 2 is: the protective frame 2 includes a protective shell 21 which is sleeved on the outside of the circular saw combination 1, the protective shell 21 is rotatably connected to the sleeve 112, and a protective groove 211 for accommodating the circular saw combination 1 is opened in the protective shell 21; through the setting of the protective shell 21 and the protective groove 211, the purpose of partially covering the entire circular saw combination 1 can be achieved, and a certain protection can be provided to the operator when performing cutting operations.

[0026] Additional, see Figure 1 As shown, due to the semicircular setting of the protective shell 21 mentioned above, the sleeve 112 in the circular saw combination 1 cannot be effectively connected and installed with the protective shell 21. In order to solve this type of problem, in this embodiment, the protective shell 21 extends downward on one side close to the sleeve 112 to form a mounting plate 212 for the sleeve 112 to extend into, and the mounting plate 212 is concentrically arranged with the circular saw combination 1; the setting of the mounting plate 212 can achieve the purpose of orderly installation and setting of the cylinder body and the circular saw combination 1.

[0027] It should also be noted that the specific structure of the above-mentioned protective member 3 is as follows: the protective member 3 includes a plurality of protective pulleys 31 arranged between the outer side of the circular saw assembly 1 and the side wall of the protective groove 211, and a plurality of the protective pulleys 31 are provided with rotating shafts rotatably connected to the protective groove 211; by arranging a plurality of protective pulleys 31 in the gap between the circular saw blade and the protective groove 211, it is possible to prevent waste chips generated during the cutting process from splashing inward and falling on the position of the circular saw blade and the sleeve 112, thereby avoiding subsequent wear on the circular saw blade.

[0028] It should be noted that in order to protect the inner wall of the protective shell 21 from the impact of waste chips, in this embodiment, a protective pad 23 is provided on the side wall of the protective groove 211 for protecting the circular saw assembly 1 from cutting; the provision of the protective pad 23 can achieve the purpose of protecting the inner wall of the protective shell 21.

[0029] Furthermore, in order to ensure the stability of the above-mentioned protective shell 21, in this embodiment, the protective groove 211 is located on the outside of the sleeve 112 and is mounted on a support plate 221, and the support plate 221 is wrapped on the outside of the sleeve 112, and a number of connecting rods 22 for fixing the support plate 221 are provided between the support plate 221 and the protective shell 21; the purpose of stably setting the protective shell 21 can be achieved by setting the support plate 221 and the connecting rods 22.

[0030] It is worth mentioning that in order to enable the first saw blade 11, the second saw blade 12 and the third saw blade 13 to better process and cut the workpiece, in this embodiment, chip grooves 111 for chip removal are arranged at intervals on the outer periphery of the first saw blade 11, the second saw blade 12 and the third saw blade 13; the setting of the chip grooves 111 can enable the circular saw combination 1 to better perform cutting work.

[0031] 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.
