Cutting tool with cutting function

This creation relates to a type of cutting tool, in particular to an innovative clip structure type revealer that has a cutting function.

Shears (also known as scissors) are one of the hand tools that people often use in their daily lives. Whether in administrative paperwork, kitchen work or process technology, the cutting tools bring considerable convenience to users. .

Generally, the structure of the cutting tool is quite simple, and is mainly composed of a pair of blades and a handle which are arranged in a crosswise manner, and a shaft member is pivotally combined with each other at the intersection, thereby forming a pass through the two. The opening and closing operation of the handle can relatively interlock the function of cutting and cutting the two blades.

The development of the structure of the conventional cutting tool has been a long history, but its function has few gains. As a result, in the face of fierce market competition, it is difficult for the industry to separate consumption from competitors. The favor of the people, in addition, has also caused the problems and shortcomings of the shearing products that have not been significantly improved in terms of functionality and added value. It is an important technical issue that the relevant industry continues to ponder.

Therefore, in view of the problems existing in the above-mentioned conventional cutter structure, how to develop an innovative structure that is more ideal and practical, and the users are looking forward to it, and the relevant operators must make efforts to develop the breakthrough goal and direction; Therefore, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The main purpose of this creation is to provide a cutting tool with cutting function. The technical problem to be solved is to make an innovative breakthrough in how to develop a new type of cutting tool structure with more ideal and practicality.

The technical feature of the present invention is mainly that the cutting tool comprises: a first blade having a coupling section at one end, and a first cutting edge portion on one side of the first blade, away from one side of the first cutting edge portion The first blade is provided with a first shaft hole between the joint portion and the first cutting edge portion; the first handle is connected and fixed to the joint portion of the first blade, and the first handle is provided The second blade has a sliding relationship with the first blade, the one end of the second blade has a sliding section, and the second blade has a second cutting edge and a first cutting edge. The cutting function is selectively opened and closed to form a shearing function, and the second blade is provided with an elongated shaft hole opposite to the first shaft hole; the second handle is disposed on the side of the first handle Wherein, the second handle is provided with a second finger hole, the second handle is provided with a second shaft hole near the end, and the second handle extends along the sliding guide groove for the second blade to slide The segment is set to be in a selectively slidable telescopic displacement state, and the second blade is configured to have an elongated state and a shortened state; Providing a hole in the first shaft, an elongated shaft hole and the second shaft hole to form a pivot point for opening and closing between the first blade and the second blade; the blade locking control member is mounted on the second handle The blade locking control member is configured to position the telescopic state of the second blade at a position corresponding to the second blade; and the distance between the second blade portion of the second blade and the axis of the screw axis is smaller than the first The distance from the back edge of the blade to the axis of the screw shaft forms a cutting distance between the second cutting edge portion and the back edge portion of the blade.

With this innovative and unique design, this creation can be compared with the prior art, and the cutting tool can also have the cutting function, thereby achieving the practical and progressive improvement of the function and added value of the cutting tool and satisfying the multi-use requirement.

Another object of the present invention is that the cutting tool further includes another technical feature that the cutting blade is attached to one side of the first blade away from the first cutting edge portion when the user wants to use the cutting function. The second blade is adjusted to shorten the positioning state, and the cutting blade is used to cut the target downward, so that the cutting function can also be achieved.

Please refer to Figures 1, 2 and 3 for a preferred embodiment of the cutting tool having the cutting function. However, these embodiments are for illustrative purposes only and are not limited by the structure in the patent application. .
