Novel tapping cutter

Abstract

The invention discloses a novel tapping cutter. The novel tapping cutter comprises a cutter handle, a straight-groove milling cutter body and an oval-groove milling cutter body; one end of the straight-groove milling cutter body is integrally connected with the cutter handle, and the other end of the straight-groove milling cutter body is integrally provided with an external thread for being connected with an internal thread of the oval-groove milling cutter body; the outer diameter of the oval-groove milling cutter body is larger than that of the straight-groove milling cutter body, and the front end face of the oval-groove milling cutter body directly acts on the surface of a rubber tree trunk. The combined cutter formed by combining the two milling cutter bodies has a special shape, sothat a required guide groove is cut out to make rubber liquid flow down along the guide groove, collection is facilitated, and waste is not caused; the cutting speed of the cutter is high and stable,and the situation that saw dust residues exist in the groove and contaminate the rubber liquid can be avoided; the overall service life of the milling cutter bodies is longer than that of existing handheld tapping cutter blades, and the milling cutter bodies are more durable; limiting balls are installed at the front ends of the milling cutter bodies to limit the depth, entering the tree trunk, ofthe milling cutter bodies.

Description

technical field [0001] The invention relates to the technical field of rubber tapping tools, in particular to a novel rubber tapping tool. Background technique [0002] The existing hand-held rubber tapping knife can only cut a plane at the corresponding position. When the rubber flows down, it will overflow and stay directly from the knife mark and cannot be collected. Moreover, there is an error in the tapping depth, which is easy to cause damage to the xylem of the trunk and affect the growth of the rubber tree. At the same time, the traditional hand-held rubber tapping knife requires a certain amount of tapping experience, and the range of objects used is narrow, and there are also problems of low work efficiency. Contents of the invention [0003] The invention proposes a new type of rubber tapping tool, which uses the form of a milling cutter to cut the rubber tree, and uses a combined tool to cut out the required cross-sectional shape, which solves the need to cut o...
