Description
Technical field
The present invention relates to electric tool technical field, is specifically a kind of gardens Gao Zhijus.
Background technology
At present, in fruit growing and afforestation, often to prune the branch of eminence, crotch.The Gao Zhiju of prior art generally includes saw head group part, connecting rod assembly and Handleset, the two ends of connecting rod assembly are connected to saw head group part and Handleset respectively, by the operation of Handleset, saw head group part can be realized to the pruning work of eminence branch, crotch.But, there is following shortcoming in this gardens Gao Zhiju: because Gao Zhiju is to eminence branch, the pruning work of crotch, distant from Handleset of saw head group part, in other words, the length of connecting rod assembly is longer, and these saw head group parts, connecting rod assembly is made up of metal material again usually, therefore, the heavier-weight of overall Gao Zhiju, and it is longer once connecting rod length component, on the one hand, the vibration that top saw head operationally produces can directly have influence on connecting rod assembly and Handleset, the length of connecting rod assembly is longer, the vibration produced is larger, the stationarity of work is poorer, on the other hand, the distortion that connecting rod assembly produces in the course of the work is comparatively large, and the operating accuracy of saw head can not ensure, is also difficult to control, therefore, in sum, the entire length of gardens of the prior art Gao Zhiju is shorter, can not prune the branch of higher trees, crotch.
In addition, what the clutch transmission due to the Gao Zhiju of prior art adopted is gear drive, and in order to play the object of protection motor when being subject to external force, gear is normally allowed to skid, therefore, between gear and cutting out section, friction plate and spring can be set, in other words, friction plate, gear, second piece of friction plate and spring connect successively and make to keep certain axial compressive force between them, the object of deceleration can be realized like this by the friction between friction plate and spring, but, friction between friction plate and spring can cause the wearing and tearing of part, axial compressive force between these parts is diminished gradually, thus frictional force is diminished gradually, finally cause shrub and hedge trimmer also can produce skidding when being subject to less external force, thus shrub and hedge trimmer can not be worked to normal reliable.
Summary of the invention
Technical problem to be solved by this invention is, provides one can prune higher trees, and stable operation, on-deformable gardens Gao Zhiju.
For solving the problems of the technologies described above, gardens provided by the invention Gao Zhiju, comprise saw head group part, connecting rod assembly and Handleset, described saw head group part and Handleset are connected to the top and bottom of connecting rod assembly; Described saw head group part comprises casing, drive motors, transmission mechanism and saw cutter, and drive motors is connected with saw cutter by transmission mechanism; Described casing comprises the tube connector held together and casing ontology be made up of engineering plastics, and drive motors and transmission mechanism are installed in casing ontology, and tube connector is socketed in the upper end of connecting rod assembly and locks connection; After the axis of casing ontology and the axes intersect of tube connector, there is an angle.Described transmission mechanism comprises input gear, output gear and eccentric block component, and input gear is connected with the output shaft of drive motors, and the output gear engaged with input gear to be rotatably connected in casing ontology and to be connected with saw cutter by eccentric block component; Described eccentric block component comprises eccentric block and eccentric block overcoat, and one end close-fitting of eccentric block is in one end of eccentric block overcoat, and the other end of eccentric block overcoat is connected with output gear; Described output gear is pushed against between output gear and wearing plate, between wearing plate and pad and between pad and butterfly spring mutually by the connection of locking nut and eccentric block overcoat after being connected with towards the side of sawing cutter wearing plate, pad and the butterfly spring be made up of Wear-resistant engineering plastic in turn.
Described connecting rod assembly is the multistage sleeve pipe be made up of engineering plastics, to be removablely connected between sleeve pipe with sleeve pipe for telescopic.
As improvement, described casing is made up of the two halves casing unit axially separated, two halves casing unit along edge by the removable connection of multiple screw.
Projecting end and the locking nut of described butterfly spring push against, and the other end and pad push against.
The end face of described locking nut and butterfly spring junction has boss, and described boss is socketed in the centre bore of butterfly spring.
Described eccentric block component also comprises the brake block and torsion spring that are all positioned at eccentric block overcoat, and one end of torsion spring is tightly placed in outside brake block, and the other end is tightly placed in eccentric block; Described eccentric block overcoat is connected as a single entity by brake block and torsion spring and eccentric block.
After adopting above structure, the present invention compared with prior art, has the following advantages:
1) because the casing in saw head group part and connecting rod assembly are all made up of engineering plastics, the characteristic such as high strength, resistance to impact of utilizing works plastics itself, make the weight saving of whole Gao Zhiju on the one hand, even if trees are higher, the vibration that saw head operationally produces is greatly reduced to the Oscillation Amplitude on Handleset by connecting rod component passes, more ensure the job stability of Gao Zhiju, be more conducive to operation; The casing that the vibration that Gao Zhiju produces in the course of the work on the other hand can be made by engineering plastics and connecting rod assembly partially absorb, and after vibration reduces, the deflection of connecting rod assembly diminishes, and the operating accuracy of saw head is guaranteed;
2) due between output gear and wearing plate, between wear-resisting and pad and between pad and butterfly spring, all produce axial pressure by the connection of locking nut and eccentric block overcoat and utilize frictional force mutually to push against, when shrub and hedge trimmer are in normal operating conditions, these parts are connected as a single entity, synchronous axial system, thick branch or the rigid objects such as the iron wire be mixed in branch or steel wire is encountered once shrub and hedge trimmer, the external force of moment is greater than the coupling mechanism force of locking nut, cause between output gear and wearing plate, all skidding can be produced between wearing plate and pad and between pad and butterfly spring, therefore, the effect of deceleration can be reached at short notice, good braking effect,
3) simultaneously, the wearing plate adopting the strong Wear-resistant engineering plastic of anti-wear performance to make contact with output gear and connects, and can reduce the damage that output gear causes it due to the friction of skidding generation, greatly increase the service life;
4) boss on locking nut end face serves the position-limiting action to butterfly spring, makes butterfly spring position in the course of the work more stable, thus more balanced to the active force of pad.
