Description

[Detailed description of the invention] [Industrial field of application] The present invention provides a cutting tool with a blade opening that allows the opening of the cutting tool to be easily adjusted to suit the size of the object to be cut. This relates to an adjustable cutting tool.

[Problems that conventional techniques and ideas attempt to solve]

The cutting tool has the base of the blade section pivoted in a crossed manner, and is provided with springs that always try to open the blade section.

Although a stopper device has been developed that regulates the degree of opening and prevents it from opening more than necessary, no stopper device that can easily adjust the degree of opening has been proposed.

If the degree of opening cannot be easily adjusted, it will be impossible to cut objects larger than the degree of opening.

[Means for solving problems]

The present invention solves this problem, and its structure will be described in detail with reference to the accompanying drawings as follows.

In a cutting tool a, the bases of the blade parts 1 and 2 are pivoted in a crossed state and are provided with a spring 3 that always tries to open the blade parts 1 and 2. A blade opening characterized in that a stopper plate 6 that engages with an outer locking step 5 of a blade part 1 connected to the blade part 1 is attached so as to be slidable up and down, and a fixture is provided to fix the stopper plate 6 at a desired position. This relates to a cutting tool whose degree is adjustable.

[Effect]

A stopper plate 6 is attached to one side of the shaft attachment part of the cutting tool a, and by sliding the stopper plate 6 upward and tightening and fixing it with the bolt 9, the outer locking stepped portion 5 is attached.
Since the distance between the upper edge of the stopper plate 6 becomes shorter, the outer locking step 5 hits the upper edge of the stopper plate 6 as soon as the blade parts 1 and 2 are opened, so that the blade parts 1 and 2 as shown in FIG. The opening degree l of No. 2 becomes smaller.

Conversely, if the stopper plate 6 is slid downward and fixed by tightening with the bolt 9, the distance between the outer locking step 5 and the upper edge of the stopper plate 6 becomes longer, so when the blades 1 and 2 are opened, the outer locking is removed. Since the stop portion 5 opens until it hits the upper edge of the stopper plate 6, the degree of opening l of the blade portions 1 and 2 increases as shown in FIG.

〔Example〕

The stopper plate 6 in the drawing is of a channel type that fits exactly on one side of the shaft attachment part of the cutting tool a, and a long slide window 7 is bored in the lower part of this channel type stopper plate 6. Seat 8 on the outside of
This figure shows a case in which the stopper plate 6 is slidably provided by inserting a bolt 9 through the handle and screwing the bolt 9 into a screw hole 11 drilled in the side surface of the tip of the handle 10 that connects to the blade part 2. .

This stopper plate 6 is not limited to a channel type, but may be a single plate shape, and in short, the upper edge of the stopper plate 6 engages with the outer locking step 5 of the blade portion 1 that connects to the handle 4 on the opposite side. Any shape is fine.

In addition, the slide mechanism is not limited to what is shown in the diagram.
Any mechanism may be used as long as it can slide.

[Effect of idea]

As described above, the present invention is a cutting tool in which the base of the blade is pivoted in a crossed manner and a spring is provided to constantly try to open the blade. A stopper plate that engages with the outer locking step of the connecting blade is attached, and a fixture is provided to fix the stopper plate at a desired position.When the blade is opened, the outer locking step of the blade will be placed above the stopper plate. Since the blade collides with the edge, the opening state of the blade is regulated and the opening is always constant, which makes cutting easier.

At this time, the stopper plate is provided so that it can slide up and down, and a fixture is provided to fix the stopper plate in a predetermined position, so by sliding the stopper plate up and down, you can easily make the opening of the blade smaller or larger, so let's cut it. The opening degree of the blade can be easily adjusted according to the size of the object to be cut, and the opening state suitable for the object to be cut can always be maintained.

Furthermore, since the structure is simple, it is extremely easy to process into existing cutting tools, and the opening degree of the blade can be freely adjusted, making it possible to mass produce and provide products at low prices. It becomes a cutting tool.
