BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. 1A is a cross-sectional view taken along the length direction of the hair clipper blade, and FIG. 1B is a cross-sectional view taken along the line AA of FIG.
FIG. 2 is an overall sectional view with some parts omitted.

The garden clipper 10 has a clipper blade 12 protruding from the front of the housing 11, a grip 14 having a switch 13 provided at the upper portion, an auxiliary grip 15 provided above the housing 11, and a root portion of the clipper blade 12. A protective cover 16 is attached to the. A motor 17 and a deceleration block 18 are provided inside the housing 11, and an eccentric cam 20 is attached to an output shaft 19.

The clipper blade 4 includes a lower push plate 1 and an upper push plate 2.
The rivet-like connecting portions 3 are spaced apart in the longitudinal direction.
And the upper blade 4 and the lower blade 5 are reciprocally held between the lower push plate 1 and the upper push plate 2.

The upper cam 20a of the eccentric cam 20 engages with the engaging hole 4a of the upper blade 4, the lower cam 20b engages with the engaging hole 5a of the lower blade 5, and the motor 17 and the deceleration block 18 output. The shaft 19 is rotated at a low speed so that the upper and lower blades 4 and 5 can be reciprocally driven. The upper and lower blades 4, 5 are in the form of hair clippers and cut the branches and the like in cooperation with the upper and lower blades 4, 5. Incidentally, it is also possible to adopt a drive mode in which one of the upper and lower blades 4 and 5 is driven.

As shown in FIG. 1, projecting portions 6 projecting below the coupling portion 3 are formed by bending the both sides of the lower pressing plate 1 in the width direction. According to such a configuration, when pruning the garden tree, it is possible to prevent a branch or the like from colliding with the joint 3 by the protrusion 6 that protrudes below the joint 3, and the branch or the like hits the joint 3. As a result, the connecting portion 3 is not damaged and the connecting function is not loosened, and the reciprocating motion of the upper and lower blades 4 and 5 held between the vertical pressing plates 1 and 2 can be stabilized, which is stable for a long period of time. The hair clipper function can be obtained. In this case, the cover portion 21 is also projected upward by bending both side portions in the width direction of the upper push plate 2.

As described above, since the lower push plate 1 is provided with the projecting portion 6 projecting downward from the connecting portion 3, the projecting portion 6 projecting downward from the connecting portion 3 causes the connecting portion 3 to be projected in the pruning of the garden tree. It is possible to prevent the branches from colliding,
A branch or the like hits the joining portion 3 so that the joining portion 3 is not damaged and the joining function is not loosened, and reciprocating motion of one or both of the upper and lower blades 4 and 5 held between the vertical pressing plates 1 and 2 is prevented. It can be stabilized, and a stable hair clipper function can be obtained over a long period of time.

[0024]

According to the first aspect of the present invention, the lower push plate and the upper push plate are joined at the joining portion, and one or both of the upper blade and the lower blade are reciprocated in the length direction between the lower push plate and the upper push plate. It is a garden tree clipper that is movably held, and since the lower push plate is provided with a protruding portion that protrudes below the connecting portion, when pruning the garden tree, the protruding portion protruding below the connecting portion causes the connecting portion to branch, etc. Can be prevented from colliding,
There is no risk of the joint function being loosened by hitting a branch or the like on the joint part, and the joint function will not loosen, and it is possible to stabilize the reciprocating motion of one or both of the upper and lower blades that are held between the upper and lower push plates for a long period of time. There is an advantage that a stable hair clipper function can be obtained over the entire range.

In the third aspect, in addition to the effect of the first aspect, the projecting portion is provided intermittently in the lengthwise direction and in the vicinity of the coupling portion, so that the projecting portion exists only around the coupling portion. However, there is an advantage that it is possible to reduce the possibility that branches or the like are caught on the protrusion during the work such as pruning and to reduce the workability due to the provision of the protrusion.

In the fourth aspect, in addition to the effect of the first aspect, since the protruding portion is formed on the peripheral portion of the joint portion, the protruding portion exists only on the peripheral portion of the joint portion, and pruning or the like occurs. There is an advantage that it is possible to further reduce the possibility that the branch is caught on the protrusion during the work and the workability is deteriorated because the protrusion is provided.

In the fifth aspect, in addition to the effect of the first aspect, since the projecting portion is provided between the coupling portions, the projecting portion causes a branch or the like to be formed on the lower push plate portion between the coupling portions. It is possible to prevent abutting, and it is possible to drive, for example, the lower blade with a low load without increasing the sliding contact resistance between the lower pressing plate and the lower blade due to the contact of a branch or the like with the lower pressing plate. There is.

In the sixth aspect, in addition to the effect of the third aspect, a flat portion lower than the protruding portion is formed between the coupling portion and the protruding portion, so that the flat portion lower than the protruding portion is pushed down. There is an advantage that the work of connecting the plate and the upper push plate can be easily performed and the assembly can be easily performed.
