Description

Drilling tool

This creation relates to a machining tool, especially to a drilling tool.

Existing woodworking drilling tools, as shown in FIG. 1, usually insert a cylindrical adapter P into the joint of the drilling machine, so as to achieve the purpose of assembling the drilling tool with the drilling machine. Due to the bulky size of the commercially available drilling machine, the staff wanted to try to replace the drilling machine with an electric drill. However, most of the joints of commercially available electric drills can only be butted with workpieces with hexagonal column joints, so the existing drilling tools are still not suitable for electric drills.

Therefore, the main purpose of this creation is to provide a drilling tool suitable for different types of machine tools.

To achieve the above objective, a drilling tool provided by an embodiment of the present creation includes: a cutter head, including a cutting member and an adapter member, one end of the cutting member is connected to the adapter member, and the cutting member is opposite to the other One end includes a plurality of wing portions and a positioning portion, the plurality of wing portions surround the positioning portion, and the outer periphery of the working surface of each wing portion is provided with a cutter, and the cutter and the positioning portion protrude from the working surface , The adapter is adapted to be inserted into a connector of a first type of implement; and an extension piece is connected to the adaptor, the extension is adapted to be inserted into a connector of a second type of implement, the first The type is different from the second type, and the cross-section of the adapter and the cross-section of the extension are perpendicular to the axis of the drilling tool and have different shapes.

In another embodiment, the end of the adapter member away from the cutting member has a receiving groove, and the receiving groove is used for receiving the extension member.

In yet another embodiment, the extension piece and the fitting piece are integrally formed.

In still another embodiment, one side periphery of the working surface of each wing portion is provided with a protruding tongue extending in the radial direction, and the protruding tongue protrudes from the working surface.

In still another embodiment, at least part of the extension member is in the shape of a hexagonal column.

In still another embodiment, the shape of the adapter is a cylinder.

In still another embodiment, the length of the adapter on the axis is greater than or equal to 1.8 cm.

In yet another embodiment, the working surface is inclined to the axis.

In this way, the drilling tool provided by this creation can be applied to different types of tools by arranging different-shaped cylindrical bodies on the connecting shaft of the tool.

Please refer to FIG. 2 to FIG. 5, a drilling tool provided by an embodiment of the present creation includes a cutter head 1 and an extension piece 2.

The cutter head 1 includes a cutting part 11 and an adapter part 12. One end of the cutting member 11 is connected to the adapter 12, and the opposite end of the cutting member 11 includes a plurality of wing portions 13 and a positioning portion 14. The plurality of wing portions 13 surround the positioning portion 14, and each wing portion 13 works The outer peripheral edge 132 of the surface 131 is provided with a cutter 15, and the cutter 15 and the positioning portion 14 protrude from the working surface 131. The shape of the adapter 12 is a cylinder. The adapter 12 is suitable for being inserted into a joint of a first type of tool (such as a drilling machine). The length of the adapter 12 on the axis C is greater than or equal to 1.8 cm.

One side peripheral edge 133 of the working surface 131 of each wing 13 is provided with a protruding tongue 16 extending in the radial direction. The protruding tongue 16 protrudes from the working surface 131. The working surface 131 is inclined to the axis C.

The extension member 2 is suitable for being inserted into a joint of a second type of implement (such as an electric drill). The first type is different from the second type. The adapter 12 has an accommodating groove 121 at an end away from the cutting member 11, and the accommodating groove 121 is used for accommodating the extension member 2. Part of the extension piece 2 is in the shape of a hexagonal column, and part of the extension piece 2 is in the shape of a cylinder. The opening of the accommodating groove 121 is circular, so the extension member 2 having a cylindrical portion can be inserted into the opening of the accommodating groove 121 that is also circular, as shown in FIGS. 2 and 5. The cross section of the adapter 12 and the cross section of the extension member 2 are perpendicular to the axis C of the drilling tool and have different shapes.

Please refer to FIG. 6, this creation further provides another drilling tool, which includes a cutter head 1 and an extension piece 3. The cutter head 1 shown in FIG. 6 is the same as the cutter head 1 shown in FIG. 2, so it will not be repeated. One end of the extension piece 3 is cylindrical, which is suitable for being inserted into a joint of a third type of tool (such as a small drill). The opposite end of the extension piece 3 has a hexagonal column shape for being inserted into the accommodating groove 121 of the cutter head 1.

Although in this embodiment, the extension piece 2 and the adapter piece 12 are assembled, the invention is not limited to this. In other embodiments of the invention, the extension piece and the adapter piece may be integrally formed.

Although this creation is disclosed above with the aforementioned embodiments, these embodiments are not intended to limit the creation. Without departing from the spirit and scope of this creation, all changes, modifications, and combinations of implementation patterns are within the scope of patent protection of this creation. For the scope of protection defined by this creation, please refer to the attached scope of patent application.
