[0020] like Figure 1 to Figure 2 As shown, the grooving tool includes six circular cutter discs 1 and a shaft body 2. The circular cutter disc 1 is connected to the shaft body 2. A through hole is opened on the circular cutter disc 1 for the shaft body 2 to pass through. The through hole is placed in the middle of the circular cutter disc 1. A screw is installed at one end of the shaft body 2. The screw passes through the shaft body 2 and is fixedly connected to the circular cutter disc 1.

[0021] A plurality of blades 3 are installed on the circular cutter disc 1. The blades 3 surround the outer wall of the circular cutter disc 1. The blades 3 are fixedly connected to the circular cutter disc 1. The wooden product can be grooved by the blades 3. Since six circular cutter discs 1 are installed, different groove depths can be created for the wooden product.

[0022] A baffle plate 4 detachably connected to the shaft body 2 is mounted on the shaft body 2. The baffle plate 4 can be placed arbitrarily between adjacent annular blades 3. The diameter of the baffle plate 4 is larger than the diameter of the annular cutter disc 1. The baffle plate 4 can block dust and debris generated during the grooving process.

[0023] The baffle 4 includes a first connection plate 5 and a second connection plate 6, which are detachably connected and are respectively connected to the shaft body 2. An extrusion block 7 is installed on the inner wall of the first connection plate 5 and the second connection plate 6. The extrusion block 7 is elastic. A positioning hole 8 is opened on the shaft body 2. The extrusion block 7 extends into the positioning hole 8 and is pressed and fixed with the positioning hole 8.

[0024] Both ends of the first connection plate 5 are provided with convex plates 9 , and both ends of the second connection plate 6 are provided with positioning grooves 10 , so that when the extrusion block 7 is engaged and fixed with the positioning hole 8 , the convex plates 9 are placed in the positioning grooves 10 .

[0025] Working principle: When two circular cutter discs 1 are needed to groove wooden products, the first connecting disc 5 and the second connecting disc 6 are placed between the second circular cutter disc 1 and the third circular cutter disc 1, the extrusion block 7 is engaged and fixed with the positioning hole 8, and the convex plate 9 is placed in the positioning groove 10, so that the first connecting disc 5 and the second connecting disc 6 are fixedly connected to the shaft body 2. When a deeper groove is required, force is applied outward at the same time to separate the extrusion block 7 on the first connecting disc 5 and the second connecting disc 6 from the engagement with the positioning hole 8, and the first connecting disc 5 and the second connecting disc 6 are pulled away from the adjacent circular cutter discs 1, and then the baffle disc 4 is placed between the adjacent circular cutter discs 1.

[0026] Since the diameter of the baffle plate 4 is larger than the diameter of the circular cutter disc 1 , dust and debris generated by the circular cutter disc 1 during the grooving process of the wooden product will be blocked by the circular cutter disc 1 and the baffle plate 4 .

[0027] Since the first connecting plate 5 and the second connecting plate 6 are both detachably connected to the shaft body 2 and the first connecting plate 5 and the second connecting plate 6 are also detachably connected to each other, the depth of the grooving of the wood product can be adjusted by the circular cutter disc 1, and the baffle plate 4 is placed between suitable adjacent circular cutter discs 1, thereby blocking the dust and debris generated by the grooving.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
