Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a jigsaw structure that is safe to work with and easy to use.

[Prior Art] A jigsaw is used to cut a board in a curved manner, and the curved cut is not limited to cutting at right angles to the board, but also cutting at an angle to the surface of the board. .

This kind of cutting requires skill from the operator, who manually controls the reaction force of the saw blade and the progress of the cut, and failure is not only dangerous but can also damage the saw blade. It was inconvenient.

In particular, it is said that jigsaws have thin and weak saw blades, and since the saw blade reciprocates, it is difficult to use the jigsaw properly unless you are used to it, as you may fail to operate it due to the inconsistent reaction force.

[Problems to be solved by the invention] The present invention was developed in view of the above circumstances, and by improving operability, it is safe and risk-free, and cutting can be easily performed even by an amateur. It aims to provide a jigsaw of construction.

[Means for Solving the Problems] The present invention has a base at the bottom of the gear section that is inclined by an axis whose longitudinal direction is the working direction of the saw blade, and a handle at the top of the gear section. The problem is solved by providing a handle and configuring the handle to be inclined in the same direction as the base.

[Function] When the base is tilted, the handle can also be tilted and used.

Therefore, the operator can easily apply a force in the right angle direction to the base via the handle.

[Example] The present invention will be explained based on an embodiment shown in the drawings. Fig. 1 is a perspective view of a jigsaw according to the invention, and Figs. 2 and 3 are front views thereof. .

FIG. 4 is a vertical cross-sectional view of the main parts of the handle of the jigsaw according to one embodiment of the present invention.

In FIG. 1, the jigsaw is provided with a gear section 2 at the front of an electric motor 1, and a saw blade 3 that reciprocates and protrudes from the lower part of the gear section 2.

The saw blade 3 is provided by penetrating a base 4 provided at the lower end of the gear part 2, and the base 4 is attached to the base 4, which has a shaft whose longitudinal direction is the operating direction of the saw blade 3. A section 5 is formed, which is configured to rotate by means of this attachment section 5 and is configured to be inclined with respect to the saw blade 3.

Furthermore, a handle 6 is attached to the upper part of the gear part 2, and is configured so that an operator can grasp and operate the handle 6.

In FIG. 2, the jigsaw cuts the plate 7
It is placed so as to be placed on the upper surface of the plate 7, and is configured to cut the plate 7 with the saw blade 3.

In FIG. 3, the base 4 is tilted and the plate 7
The saw blade 3 is inclined with respect to the plane.

A handle 6 is rotated on the upper part of the gear part 2 and is formed vertically.

In FIG. 4, the handle 6 of the jigsaw is screwed onto a bolt 8 provided on the upper part of the gear part 2, and the lower end 9 of the bolt 8 is pivoted, and as indicated by an arrow 10, the handle 6 It is configured to oscillate.

The swinging handle 6 is configured to come into contact with a curved surface 11 formed on the upper part of the gear part 2 via a collar 12. When the handle 6 is tightened, the bolt 8 is pulled and the handle 6 is moved to the collar 12. is configured to press against the curved surface 11.

In such a configuration, when cutting the board 7, the jigsaw has the handle 6 and the base 4 straight, as in a conventional jigsaw, when cutting the board 7 with the saw blade 3 perpendicular to the board 7. and can be cut.

When cutting by tilting the saw blade 3 relative to the plate 7 as shown in FIG. 3, the base 4 is tilted and placed on the plate 7, and the handle 6 is loosened and rotated. Then, as shown in FIG. 3, tighten the handle 6 by screwing it into place so that it is vertical.

With this configuration, the handle 6 of the jigsaw can be adjusted even though the gear portion 2 is inclined during cutting.
can be operated by pressing down from above, and a pressing force can be applied perpendicularly to the cut surface of the plate 7 together with the reaction force of the saw blade 3.

That is, by rotating the handle 6, the handle 6 moves so as to be close to the cutting part of the plate 7 by the saw blade 3, and therefore the direction of movement of the saw blade 3 when viewed from the part of the saw blade 3 that acts on the plate 7. Since the saw blade 3 is biased toward the opposite side, the reaction force of the saw blade 3 and the necessary operations for cutting the plate can be easily performed.

Further, the handle 6 can be easily operated and convenient if the handle 6 is fixed by screwing as in this embodiment.

In addition, since the handle 6 is usually formed in a large size, it is convenient because it can be easily and strongly fixed by screwing.

Furthermore, if the handle 6 is formed to have a long distance from the pivoted part of the lower end 9 of the bolt 8 to the operated part of the handle 6, the handle 6 can be easily moved when the handle 6 is rotated and tilted. , set this appropriately and take into consideration the reaction force of the saw blade 3 when rotating the handle 6 and the relationship between the force pressing against the cut surface of the plate 7 and set it at a convenient position. It is recommended to configure it so that

[Effects of the invention] As described above, according to the invention, the handle is configured to be tilted so that when the main body is tilted, the handle can be moved to a position where the reaction force and the position of action of the saw blade are effective. It is easy to operate, does not fail even when cutting a board diagonally, and can be cut with confidence, so its practical value is extremely great.
