Description

Trimming tool

This creation is about a woodworking appliance, especially a trimming tool used after woodworking.

Generally, all kinds of woodware and furniture, in order to avoid sharp corners which are easy to injure people, and the burrs generated by them, during the processing, the corners must be modified for their right angles. Moreover, in order to make the touch and the appearance of the wooden surface, the wood grain or various skins are usually applied to the surface for beautification. However, after the skin is to be applied, the residual material is often generated at the right angle. At this time, the trimming tool is used for cutting and trimming.

A conventional trimming cutter such as the trimming blade described in Taiwan Patent No. M243345 is provided with a V-notched edge at the intersection of two perpendicular abutting faces, by which the trimming edge abuts against the vertical corner of the wood. By cutting the trimming edge for cutting and trimming. However, since the abutting faces of the trimming edge are of the same width, that is, the edge of the V-shaped notch is located at the center, which makes it difficult to apply force in actual use. Therefore, there is an improved Taiwan patent M428040 which has an L-shaped abutting surface to increase the contact area of one of the abutting faces, thereby improving the biasing force at the time of gripping. However, the edge trimmed by the trimming edge described above will still be tiny. Oh, so there is a need for a second modification step such as sanding. Furthermore, the existing trimming tools (such as the trimming edges of the above two previous cases) cannot be operated smoothly when trimming the edges or the edges of the shallow sides.

In view of this, the creator of this case has been carefully studied and accumulated years of experience in professional research and development, and finally the birth of this creation.

The main purpose of this creation is to design a new trimming tool that can obtain a flat edge in one operation, and it can be trimmed against the edge of the traditional trimming edge that is difficult to construct.

To achieve the above object, the present invention provides a trimming cutter comprising a grip portion and an elongated blade. The holding portion has an abutting surface of an elongated shape, and the abutting surface defines a groove, and the groove divides the abutting surface into a first elongated shape and a second elongated shape. The elongated blade is clamped in the groove and protrudes from the abutting surface, and both ends of the elongated blade have two concave edges, and each concave edge is located at the abutting surface. In particular, the elongate blade is substantially perpendicular to the abutment surface.

In a preferred embodiment, the first elongated strip is larger than the second elongated strip. Further, the first elongated strip has a first width, the second elongated strip has a second width, and the first width is greater than the second width. Further, the elongated blade has a predetermined thickness, and the two concave edges are adjacent to the first elongated shape of the abutting surface.

In a preferred embodiment, the grip portion includes a vertical surface by the abutment surface The two gripping surfaces are extended, and at least one of the two gripping faces forms a concave curved surface.

In a preferred embodiment, the grip has at least one screw hole. The trimming tool of the preferred embodiment further includes at least one bolt for securing the elongate blade in cooperation with the at least one threaded hole.

Compared with the prior art, the trimming cutter of the present invention forms 90 degrees of the two sides with the abutting surface through the elongated blade, thereby abutting the convex portion at the right angle of the wood, and then moving the trimming tool by the concave shape The edge cuts off the unwanted projections to achieve a perfectly flat right angle. According to this, the trimming cutter of the present invention does not need to be modified twice, and overcomes the shortcomings of the conventional trimming edge. In addition, since the trimming tool of the present invention is abutting against the blade as a surface, it has a very thin thickness, thereby overcoming the disadvantage that the conventional trimming blade cannot work with a slit or a shallow side edge.

Figure 3 is a perspective view of the elongated blade of the preferred embodiment.

Please refer to FIG. 1 , which is a perspective view of a trimming cutter according to a preferred embodiment of the present invention. The trimming cutter 100 of the present embodiment includes a grip portion 20 and an elongated blade 40. Preferably, the grip portion 20 is integrally formed, and it is preferably made of metal. However, the present creation does not limit the material of the grip portion 20, Other suitable materials, including plastics, can be implemented.

Referring to FIG. 1 , FIG. 2 and FIG. 3 together, FIG. 2 is a bottom view of the grip portion of the preferred embodiment, and FIG. 3 is a perspective view of the elongated blade of the preferred embodiment. . As shown in FIGS. 1 and 2, the grip portion 20 has an abutting surface 22 of an elongated shape, and the abutting surface 22 defines a groove 24 defined by the groove 24 into a first surface. An elongated strip 26 and a second elongated strip 28 are provided. In the preferred embodiment, the first elongated strip 26 is larger than the second elongated strip 28, that is, the area that the first elongated strip 26 can abut is larger than the area of the second elongated strip 28. Furthermore, the first elongated strip 26 has a first width D1, the second elongated strip 28 has a second width D2, and the first width D1 is greater than the second width D2.

As shown in FIG. 1, the elongated blade 40 is clamped in the groove 24 and protrudes from the abutting surface 22. In particular, the elongate blade 40 is substantially perpendicular to the abutment surface 22 such that the elongate blade 40 can engage the first elongate shape 26 (or the second elongate shape 28) at a right angle to the wood.

As shown in Figures 1 and 3, the ends of the elongate blade 40 have two concave edges 42 at each of the abutment faces 42. That is, the concave edge 42 is located at the end of the elongated blade 40 near the intersection of the abutment surface 22 and the elongate blade 40 for eradicating the protrusion at a right angle.
