[0002] The connection of each component of a small processing equipment is usually carried out by using connecting pieces and fasteners, etc., or directly using a nail gun for connection. In the products using a nail gun, the tail of the nail is exposed on the surface of the product, seriously affecting the appearance effect of the product.

[0007] Through the above solution, after installing this processing blade on the tool holder of the milling cutter, when the milling cutter starts to rotate and cut the workpiece, the tenon-mortise cutting strip and the tenon-mortise cutting groove can respectively process the tenon and the mortise; the cutting strip cross-section and the cutting groove cross-section are centrosymmetric about a certain point on the first basic line. The two workpieces cut with this blade can be paired with each other to form a complete pair of tenon-mortise fits, reducing the trouble of using different tools to process the tenon structure and the mortise structure respectively, and providing a high precision for the fit between the tenon and the tenon-mortise, and can effectively improve the overall processing efficiency of the furniture.

[0008] As a further improvement of the above technical solution, the cross-section of the cutting strip includes a first outer side, a second outer side, and a third outer side. The first outer side, the second outer side, and the third outer side are connected in sequence. The first outer side is perpendicular to the second outer side, and the third outer side extends away from the second outer side towards the first outer side.
