After the adoption of this structure, the shear has simple and reasonable structure, easy operation, light labor intensity, high work efficiency, application in common lawn and field weeds shrub, and the like features.

Description

Lawn and shrub double-purpose disc shear
Technical field
The invention relates to the electric tool that prune in a kind of outdoor gardens, particularly a kind of circle shear of pruning weeds and shrub.
Background technology
As everyone knows, when having weeds and shrub simultaneously on the ground, pruning facility with existing conventional and be difficult to weeds and shrub are repaired simultaneously, also is the problem that outdoor pruning is had a headache the most; The rearmounted power long a swap pruning tool of general at present employing is pruned, but present rearmounted power long a swap pruning tool not only volume is big but also heavy, on machine, be equipped with a braces when using, entire machine is born on shoulder as school bag, two portable firmly two handles are used for controlling direction and control machine switch.Have the following disadvantages in the use: the one, the operator is too arduous; The 2nd, need change different working heads at different targets during work, transposing trouble, inefficiency.Therefore the outdoor gardens pruning implement that develop a kind of light labor intensity, high efficiency, can prune weeds and shrub has simultaneously become a difficult problem in the industry.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have desirable product to emerge on market so far as yet.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing rearmounted power long a swap pruning tool exists, the purpose of the invention provides a kind of circle shear that can operation in operation on the common meadow can adapt to open-air weeds and shrub again.
The invention solves the technical scheme that its technical problem adopts, it comprises operating grip, body, the motor and speed reducer structure, operating grip is connected with body, the motor and speed reducer structure is arranged on the interior support of body, before the end face of described body is provided with, back protective cover, the output shaft of reducing gear stretches out body and is fixed with movable knife disc, before movable knife disc is arranged on, in the back protective cover, preceding protective cover is provided with the circular arc serrated slot, the stationary knife dish is provided with the corresponding sawtooth edge of a knife of circular arc serrated slot and is fixed on the preceding protective cover, and the sawtooth edge of a knife of stationary knife dish and the edge of a knife of movable knife disc are complementary.
Described reducing gear comprises change-speed gearing and output shaft, the output gear shaft engagement of change-speed gearing and motor.
Be hinged with assist handle on the described body.
After adopting said structure, following advantage and effect are compared with prior art arranged: the one, because protective cover before and after on movable knife disc, being equipped with, do not need entire machine born on shoulder and work, make machine alleviate labour intensity to greatest extent in any angle work; The 2nd, movable knife disc and stationary knife dish carry out operation by cut mode, both can operation on common meadow, can adapt to operation in open-air weeds and the shrub again; The 3rd, need not change working head during operation, operating efficiency, easy to operate.

Embodiment
Fig. 1 is to shown in Figure 5, specific embodiments for the invention lawn and shrub double-purpose disc shear, it comprises operating grip 1, body 3, motor 10 and reducing gear, operating grip 1 is connected with body 3, be hinged with assist handle 2 on the body 3, be provided with support 11 in the body 3, motor 10 is arranged on the support 11 by bearing, reducing gear comprises output shaft 13 and the change-speed gearing 12 that is fixed on the output shaft 13, output shaft 13 is arranged on the support 11 by bearing, change-speed gearing 12 meshes with the output gear shaft of motor 10, protective cover 4 before and after the end face of described body 3 is fixed with, 5, output shaft 13 stretches out body 3 and is fixed with movable knife disc 6 by top board 14 and lower platen 7, protective cover 4 before and after movable knife disc 6 is arranged on, in 5, preceding protective cover 4 is provided with circular arc serrated slot 9, and stationary knife dish 8 is provided with the circular arc serrated slot 9 corresponding sawtooth edges of a knife 15 and is fixed on the preceding protective cover 4, and the sawtooth edge of a knife 15 of stationary knife dish 8 is complementary with the edge of a knife 16 of movable knife disc 6.
When the invention is mowed or brush when wood, connection is arranged on the power switch on the operating grip 1, motor 10 is started working, motor 10 drives change-speed gearing 12 rotations by output gear shaft, change-speed gearing 12 drives output shaft 13 rotations, output shaft 13 drives movable knife discs 6 rotations, and the edge of a knife 16 of movable knife disc 6 is sheared weeds or shrubs in the circular arc serrated slot 9 of protective cover 4 before entering by cooperating with the sawtooth edge of a knife 15 of stationary knife dish 8, thus realization shear simultaneously weeds and shrub purpose.
