Description

[Detailed description of the invention] This invention relates to an electric saw used to cut off unnecessary branches protruding from high places on trees, and is a method for easily cutting off thin branches without supporting them with hands. The purpose is to provide an electric saw that can

When cutting thin tree branches or the like with an electric saw, the branches must be supported by the hand, or the branches will move with the saw blade, making it impossible to cut.

The present invention involves fixing one end of a pair of support fittings made of elastic material parallel to the saw blade to the main body of an electric saw that supports the saw blade, and fixing the support fittings to the extent that a tree branch can fit into the support fittings. A stopper is provided to prevent the branch from shifting due to the size of the recess, and by fitting the branch to be cut into the recess and sandwiching it between the saw blade and the support fitting, the branch can be cut high without having to support it by hand. This allows the branches to be easily cut off.

FIG. 1 is a perspective view of an embodiment of the electric saw of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a side view of a supporting metal fitting.

In these figures, reference numeral 1 denotes the main body of an electric saw, and a well-known drive mechanism consisting of a motor, gears, cams, etc. is built inside, and the elongated saw blade 2 reciprocates in the direction of the arrow in the figure when driven by the motor. is configured to operate.

A downward taper 2a is formed at the tip of the saw blade 2, and a cutting edge 2b is formed on the father-son face.

Reference numeral 3 denotes a pair of supporting metal fittings 1, which are provided on both sides of the saw blade 2 and approximately parallel to the saw blade.The supporting metal fittings 1 are made of a long and thin elastic material, one end 3c of which is fixed to the instrument body 1 and has a button, and the tip 3a is downwardly connected. The support fitting 3 has a recess 3d large enough to fit a twig, and an edge of the recess 3d close to the main body. A stopper 3b projecting upward is provided at the portion.

When cutting off a tree twig, use the tapered part 2 at the tip of the saw blade 2.
When a wooden twig 4 is sandwiched between the bent part 3a at the tip of the support metal fitting 3 and the entire electric saw is pushed in the direction of the twig 4, the support metal fitting 3 will tilt downward due to its elasticity, and the twig 4 will become a saw blade. 2 from the tapered part 2a of the stopper 3b
One fitting is fitted into the recess 3d, and one stop is held between the saw blade 2 and the support fitting 30 at the position shown by the broken line in FIG.

When the motor is turned on in this state, the support bracket 3 does not move and only the saw blade 2 moves, so the branch 4 moves the saw blade 2.
Only the branch 4 can be cut off by reciprocating.

As described above, the present invention provides a pair of support fittings 3 made of an elongated elastic material on both sides of the reciprocating saw blade 2 in parallel with the saw blade 2.
One end 3c of the support fitting 3 is fixed to the instrument body 1 that supports the saw blade 2, and a recess 3d into which a tree twig fits and a stopper 3b for stopping the tree twig are provided in the middle of the support fitting 3. The twig is inserted between the saw blade 2 and the support fitting 3, and the twig that fits into the recess 3d is cut. At this time, the twig hits the stopper 3b and stops and easily fits into the recess 3d.The twig 4 is fixed in that position and can be easily cut without supporting the twig by hand.

Claims (1)

[Scope of utility model registration request] One end of an elongated saw blade that is reciprocated by the drive mechanism is attached to an instrument body that has a built-in drive mechanism, and the elongated saw blade is attached to an elastic material that cooperates with the saw blade to clamp the object to be cut between the saw blade and the saw blade. A pair of support fittings are provided on both sides of the saw blade in parallel with the saw blade, one end of which is fixed to the instrument main body, and a recess into which the object to be cut is fitted is provided in the intermediate portion of the support fitting, and a recess of this recess closer to the instrument main body. An electric saw characterized in that a stopper is provided on the edge of the saw to protrude in a direction for clamping an object to be cut.
