Description

[Detailed description of the invention] (Industrial application field) This invention relates to a hand trimmer for cutting wood.

(Prior art) As a conventional technology, there is, for example, Japanese Utility Model Application Publication No. 59-118504.

(Problems to be solved by the invention) In conventional hand trimmers, for example, the trimmer base was fastened to the trimmer body with bolts inserted through protruding mounting pieces installed in parallel with the trimmer base. There was a problem in that the hand trimmer and the bolt excessively protruded outward from the side surface of the trimmer base, deteriorating the operability when gripping the hand trimmer and performing cutting work.

Further, there was a problem in that the operation for adjusting the cutting depth of the bit was complicated.

An object of the present invention is to provide a hand trimmer that solves the above problems.

(Means for Solving the Problems) The hand trimmer of the present invention has a cylindrical base part formed in the trimmer base in order to fit the body part of the housing of the trimmer body. A cut-off portion is formed by cutting along the cylindrical base portion, and the base cylindrical portion is cut inside the outer surface of the body portion and on both sides of the cut-off portion. It is fastened to the body part through tightening screws inserted inwardly along the transverse cross-sectional direction of the base cylinder part, respectively, so as to be adjustable in movement in the axial direction, and on the outer surface of the body part. The exposed part exposed by the cut-off part has a scale surface that indicates the relative position of the body part and the base cylinder part.

[Effect]

A trimmer base having a cylindrical base tube portion into which a body portion of the trimmer body is fitted is fitted with a tightener that is inserted into the inside of the outer peripheral surface of the base tube portion and the inside of the outer peripheral surface of the body portion, respectively. The base cylindrical portion is fastened to the body portion with an attached screw so that the base cylindrical portion can be moved in an axial direction, thereby reducing a protruding portion on the outer circumferential surface of the base cylindrical portion.

Further, the relative position between the body part and the base cylinder part is indicated by a scale surface formed on an exposed part exposed by the cut-off part of the base cylinder part on the outer circumferential surface of the body part. Teach the depth of cut.

(Example) Next, an example of the present invention will be described with reference to the drawings.

The housing 2 of the trimmer body 1 has a battery storage part 2 formed in an oblong shape to store a battery.
a and a cylindrical body 2b for accommodating a motor, which are vertically connected to form a substantially T-shape when viewed from the front. The thick portion 2c, which has a slightly increased wall thickness near the lower front end of the body portion 2b, has a scale face 3 on which a scale 3a is displayed, and a pair of left and right scales recessed on both sides of the scale face 3, respectively. Recessed parts 4, 4
are each formed in a vertically elongated shape, and an insertion hole 5 is provided in a vertically long shape on the back side of the scale surface 3 to communicate the double concave notch 4 from its upper end to its lower end.

The bit 6 is inserted into a collector chuck 7 rotatably supported on the lower end of the trimmer body 1.

The trimmer base 8 is made of a transparent material, and has a base cylindrical portion 8a formed in a substantially cylindrical shape for slidably fitting the body 2b of the housing 2, and is connected perpendicularly to the lower end of the base cylindrical portion 8a. A side base plate 8c is provided, which is connected to the front end of the base plate 8b so as to be tiltable upward. The base cylinder part 8a is cut out along the axial direction of the base cylinder part 8a so that elastic deformation behavior of the base cylinder part 8a in the cross-sectional direction is allowed and the scale surface 3 of the body part 2b is exposed. The separated part 9 is formed in a slit shape, and an opening 10 is opened below the separated part 9 near the lower end of the base cylindrical part 8a. is scale 3 on scale face 3.
A pair of left and right point marks 11, 11 are opposed to the scale 3a on the scale surface 3 in order to indicate the relative position between the body 2b and the base cylinder 10 and teach the cutting depth of the bit 6. is displayed. Further, the base plate 8b and the side base plate 8c have a circular hole 12 for inserting the bit 6, and the side base plate 8c is attached to the upper surface of the rear end of both left and right ends of the side base plate 8c. Left and right 1 having arc-shaped elongated holes 14a on both sides of the lower end for fastening via thumbscrews 13 in a horizontal state or a predetermined tilted state.
A pair of connecting pieces 14, 14 are provided in a protruding manner.

The tightening screw 15 is a pair of protrusions 1 that protrude symmetrically from near the center of the front part of the base cylinder part 8a.
6, 16, the double concave notch 4 of the housing 2, and the insertion hole 5, respectively, and a base cylindrical portion is formed slightly inward of the outer surface of the body portion 2a and slightly inward of the outer surface of the base cylindrical portion 8a. A nut 17 is fitted into the tightening screw 15 along the cross-sectional direction of the trimmer base 8a. The body 2 is placed in a state where the scale surface 3 is exposed inside the cutout 9.
b, and can be fastened to adjust the movement of the body portion 2b in the axial direction.

Next, the operation and effects of the embodiment having the above configuration will be explained.

In this example, the body 2 of the housing 2 of the trimmer body 1
A cylindrical base tube portion 8a formed on the trimmer base 8 in order to fit the trimmer base 8 has a cutout portion 9 formed by cutting a part of the base tube portion 8a along the axial direction. The cylindrical portion 8a is attached to the inner side of the outer surface of the body portion 2b and the inner side of the outer surface of the base cylindrical portion 8a on both sides of the separation portion 9.
A tightening screw 15 inserted along the cross-sectional direction of
is fastened to the body part 2b so as to be adjustable in movement in the axial direction, and the body part 2b and the base cylinder part are attached to the exposed part exposed by the separation part 9 on the outer surface of the body part 2b. A scale surface 3 is formed to indicate the relative position with respect to 8a.

Therefore, the trimmer base 8 can be easily moved and adjusted with respect to the trimmer body 1 by the tightening screw 15, and since the tightening screw 15 passes through the inside of the base cylindrical portion 8a and the body portion 2b, the tightening screw 15 can be easily adjusted and mounted. 15 and the tightening portion excessively protruding outward from the base cylindrical portion 8a, the body portion 2b and the vicinity of the base cylindrical portion 8a become easier to grip, improving operability during cutting work, and It has the effect of improving the appearance.

In addition, in this example, the tightening screw 15 is connected to the housing 2.
Since the insertion hole 5 is inserted through the back side of the scale face 3, the problem of partially shielding the scale face 3 with the tightening screw 15 is avoided, and the depth of cut between the scale 3a and the point mark 11 is reduced. In addition to simplifying the adjustment operation, the trimmer base 8 can be fastened to the housing 2 with the tightening screw 15 to prevent it from turning and coming off.

(Effects of the invention) Since the present invention is configured as described above, it is possible to reduce the protruding portion on the outer surface of the base cylinder part, which improves the operability when gripping and moving the hand trimmer, and improves the operability of the hand trimmer. It has the effect of improving appearance.

In addition, since the relative position between the body of the trimmer body and the base cylindrical portion of the trimmer base is indicated by the scale surface, it is easy to set the cutting depth of the bit, and the tightening screw can be set within the scale surface. Since it is penetrated in the opposite direction, it has the effect of eliminating the problem of a part of the scale surface being blocked by the tightening screw.
