Compared with the traditional flat-blade cutter, the woodworking spiral cutter has better heat dissipation efficiency and wear resistance. Therefore, it can reduce the wear and deformation of the tool during the wood processing process and improve the processing quality.

[0003] Traditional woodworking spiral cutters are generally composed of multiple straight blades. This type of blade has a small contact area with the wood when planing, which can easily cause slippage during cutting and poor planing effect on the wood surface. In addition, its blades will wear or be damaged due to long-term cutting during use. If they are not replaced in time, the cutting effect of the blades will be easily affected. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a replaceable blade shaped woodworking spiral cutter, which facilitates the improvement of the contact area between the blade and the wood surface and improves the cutting efficiency by providing a blade, a blade and a connecting piece. At the same time, it is convenient to replace the blade worn out by cutting to avoid affecting the cutting effect of the wood.

[0005] The utility model also provides a woodworking spiral cutter with a replaceable blade, comprising: a cutter body, two cutting edges, a plurality of blades and a connecting piece, wherein the outer side wall of the cutter body is fixedly connected to the two cutting edges, one end of each of the two cutting edges is provided with a mounting groove, the inner wall of the mounting groove is provided with a limiting groove, the blade is installed in the mounting groove, the blade is fixedly connected to the cutting edge via a connecting piece, the connecting piece comprises a support block, a fixing bolt is provided on the support block, the cutting edge is threadedly connected to the support block via the fixing bolt, a telescopic cavity is provided at one end of the support block, the interior of the telescopic cavity is slidably connected to a limiting rod, the limiting rod is fixedly connected to a telescopic spring at one end located inside the telescopic cavity, and the end of the telescopic spring away from the limiting rod is fixedly connected to the inner bottom wall of the telescopic cavity.

[0006] According to the replaceable blade forming woodworking spiral cutter, the two blades are fixed to the outer side wall of the cutter body in a spiral shape, and the two blades are relatively symmetrical.

[0007] According to the replaceable blade forming woodworking spiral cutter, the end of the support block away from the fixing bolt is slidably connected to the mounting groove, so that the blade can be conveniently connected to the inside of the mounting groove through the support block.

[0008] According to the replaceable blade forming woodworking spiral cutter, the limiting rod is adapted to the inner wall of the limiting groove, and the limiting rod is slidably connected to the limiting groove. The limiting rod is used to limit the support block to the inner wall of the installation groove.

[0009] According to the replaceable blade forming woodworking spiral cutter, one end of the cutter body is fixedly connected to a rotating shaft, and one end of the rotating shaft is provided with a fixing rod.

[0010] According to the replaceable blade forming woodworking spiral cutter, the limiting rod is in a T-shape, so as to prevent the limiting rod from sliding out of the telescopic cavity under the action of the telescopic spring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By setting the blade, the knife blade and the connecting piece, the contact area between the blade and the wood surface is improved, the cutting efficiency is improved, and the worn blade due to cutting is replaced to avoid affecting the cutting effect of the wood; the planing effect is improved by the spiral blade.
