Description

Combined cutter

This creative department is related to tools, especially for a woodworking tool.

Wooden goods are usually assembled from different parts of the parts, and most of them are assembled by means of screw locks. In order to avoid the screw head protruding from the outer surface of the woodwork after assembly, it is usually reused outside the hole. The cutter cuts the hole suitable for accommodating the screw head, so that when the screw head is placed in the hole, it will be parallel to the outer surface of the wood product, and finally covered with the wooden sticker, so that the finished wooden product has better production quality. In addition, for the convenience of processing, a perforation is generally formed in the middle of the tool to be combined with the drill bit, so that the machining of the above-mentioned accommodating screw can be cut on the wood product in one processing procedure, such as the tool disclosed in TWM321819, CN201244842, etc. class.

However, in such conventional combined cutter technology, the distance of the blade of the tool for cutting wood products is fixed. Therefore, when cutting holes of different sizes and holes, it is necessary to replace the tool of another size. When cutting, or when you need another size drill, you need to find the corresponding size of the tool to combine with the drill bit. As a result, the processing procedure is complicated, the processing time is prolonged, and there are defects to be improved. .

Therefore, it is necessary to provide a novel and progressive combination cutter to solve the above problems.

The main purpose of this creation is to provide a combined cutter that combines two bodies to change the distance between the two blades so that the same tool can be used to cut holes of different sizes or different sizes. The combination of the drill bits does not need to be replaced from time to time, which is very convenient to use, which can effectively save processing time and improve efficiency.

To achieve the above object, the present invention provides a combined cutter for assembly in a woodworking apparatus comprising a cutting base and two cutting inserts. The cutting base has a shaft line and two bodies. The two systems are detachably coupled. Each of the bodies has a body and a seat connected to the body. The direction of the axis extends. The two cutting inserts are respectively disposed on each of the holders, and the two cutting inserts are used for cutting a wooden workpiece.
