[0026] As Figures 1 to 7 shown, a saw blade that is convenient for disassembly and replacement includes a first saw blade 1, a second saw blade 2, a third saw blade 3, and a fourth saw blade 4. The first saw blade 1, the second saw blade 2, the third saw blade 3, and the fourth saw blade 4 have the same structure. The first saw blade 1, the second saw blade 2, the third saw blade 3, and the fourth saw blade 4 are sequentially and fittingly installed to form a circular saw blade. Four blade blocks 101 are evenly arranged on the outer circumferential surface of the first saw blade 1. An installation groove 102 is formed on the side wall of the blade block 101. A diamond cutter head 5 is fixedly connected in the installation groove 102. Cutting grooves 103 are formed on both side walls of the first saw blade 1. The two cutting grooves 103 are arranged opposite to each other. The cutting groove 103 is a fan-shaped structure. Three lock holes 104 are formed at the bottom of the cutting groove 103. The three lock holes 104 enclose an isosceles triangle to ensure stability and no shaking after locking. An arc groove 105 is formed on the side wall of the first saw blade 1. The arc groove 105 and the cutting groove 103 are concentrically distributed. Card slots 106 are formed at the same positions on the front and back of the first saw blade 1. A card block 11 is clamped in one of the card slots 106. The card block 11 is engaged with the card slot 106 of the second saw blade 2 to prevent the first saw blade 1 and the second saw blade 2 from shaking and misaligning after installation, which affects the cutting quality.

[0027] The four arc-shaped grooves 105 enclose an installation hole 12, and the eight cutting grooves 103 enclose two circular grooves 13. The two circular grooves 13 are respectively located on the two side walls of the first saw blade 1. A first clamping disc 6 and a second clamping disc 7 are respectively arranged in the two circular grooves 13. A first convex ring 61 is arranged on the side wall of the first clamping disc 6, and the first convex ring 61 is clamped in the installation hole 12. A first clamping hole 62 is opened at the center of the side wall of the first convex ring 61, and four first connection holes 63 are evenly opened on the side wall of the first convex ring 61. A plurality of second connection holes 64 are opened on the side wall of the first clamping disc 6, and a hexagonal hole 65 is opened at one end of each of the plurality of second connection holes 64. A nut 10 is arranged in the hexagonal hole 65. A second convex ring 71 is arranged on the side wall of the second clamping disc 7, and the second convex ring 71 is clamped in the installation hole 12. The second convex ring 71 is attached to the first convex ring 61. A second clamping hole 72 is opened at the center of the side wall of the second convex ring 71, and four counterbore holes 73 are evenly opened on the side wall of the second convex ring 71. The counterbore of the counterbore hole 73 is opened on the side wall of the second clamping disc 7 away from the second convex ring 71.

Then, a screw 8 is installed in the counterbore 73, and its head sequentially penetrates through the counterbore 73 and the first connection hole 63 and extends to the outside, facilitating the fixed connection with an external power mechanism and preventing the saw blade from rotating. The installed saw blade is inserted into the power mechanism through the mounting hole 12 and is completely locked and fixed by a locking nut. The whole is driven by the power mechanism to rotate to cut the workpiece. With this structure, when a certain saw blade is damaged, the corresponding saw blade can be replaced separately to resume the cutting work without replacing all of them. The disassembly and replacement of the saw blade are convenient and fast, saving costs.
