[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] It should be noted that, in this utility model, unless otherwise stated, when an element is referred to as "connected to" or "set on" another element, it can be directly on the other element or may have an intervening element present simultaneously. The directional terms used, such as "upper," "lower," "left," and "right," generally refer to... Figure 1 The directions shown are up, down, left, and right. "Inner" and "outer" refer to the inner and outer parts of a specific outline. "Far" and "near" refer to the distance or proximity relative to a particular component.

[0020] like Figures 1-2As shown in the figure, a novel forming combination tool provided by an embodiment of the present invention includes: a tool holder 1, a tool head 2 and a plurality of cutting edges 3. The tool head 2 is disposed at the lower end of the tool holder 1, and the cutting edges 3 are evenly spaced at the lower end of the circumferential surface of the tool head 2. Each cutting edge 3 includes an upper cutting edge 4, a middle cutting edge 5 and a lower cutting edge 6.
