Background technique
Grass-mowing machine, pruner, GREEB HEDGE MACHINE etc. are relatively conventional gardens instruments.But existing gardens instrument exists following
Problem: grass-mowing machine is only used for weeding, and pruner is only used for pruning, and GREEB HEDGE MACHINE is only used for trimming hedgerow, has a single function, and leads to
Poor with property, corresponding different operation is just needed using corresponding instrument;To need in gardens arrangement or municipal greening pruner
Mating all types of instruments, it is not only with high costs, and carry and be also inconvenient.
And safety switch is not present in existing gardens instrument, it is hidden to there is greatly safety in the case where being easy to appear error starting
Suffer from.
Utility model content
The utility model for overcome the deficiencies in the prior art, provides a kind of gardens device of highly-safe safe operation
Tool.
To achieve the goals above, the utility model uses a kind of following technical scheme: gardens instrument of safe operation, packet
Include the grab handle, body of rod, at least cutter device with cutter head, the driving device for driving cutter head movement, scalable
Movement is to control the switch key that the driving part is powered or powers off;It is equipped with and the driving device in the cutter device
The first connecting portion part matched and the second connecting portion part with first connecting portion part transmission connection, the second connecting portion part
It is matched with the cutter head.Limiting component can effectively limit actuator and keep in off position in the utility model, will not be because of
It simply causes GREEB HEDGE MACHINE actuator to start touching for control switch, GREEB HEDGE MACHINE is effectively prevent accidentally to be opened, guarantee youngster
Cutter group will not act during child plays or operator moves GREEB HEDGE MACHINE, prevent from hurting, safer;Cutting
Device can be replaced, and to realize the conversion between different function, a tractor serves several purposes be realized, to only need to configure a fuselage
In addition multiple cutter devices, economical and practical, it is easy to carry;And integrally replaced when replacing using cutter device, it compares
For the structure of more allowing blade replacement, the stability of instrument is high, is less prone to failure;First connecting portion part and second connecting portion are set
Part is cooperated by the transmission between first connecting portion part and second connecting portion part, realizes the change of the power exported to driving device
Velocity modulation section, so guarantee driving device output power it is constant in the case where, the cutter device of a variety of different structures, revolving speed can be driven
It is acted, use scope is wide, really realizes multi-functional;Secondly, the angle between first connecting portion part and second connecting portion part
Cooperation can be adjusted as needed, so that the outbound course of power is changed, so that before cutter device and fuselage
Angle diversity, and then adapt to demand of the different operating environment to different cutter device angles;
Secondly, actuator and cutter device are split settings, driven for no setting is required in the cutter device of replacement
Moving part, cutter device it is small in size, light-weight, be not only convenient for carrying, and dismount it is more convenient laborsaving;First connecting portion part is straight

Further, further include the button of scalable movement, the limiting component can be matched with the switch key with
Switch key is set to be in the state far from the button;Limiting component can effectively limit actuator and keep cooperation in off position
Stablize.
Further, the limiting component includes the elastic component that a press section and one end are connected to the press section, the elasticity
The part other end is connected to the grab handle;The position of pressing piece correspond to switch key position be arranged, to press section carry out by
The i.e. controllable elastic component of press operation is flexible, and then realizes the flexible of press section;During press section pushes, it can release and open
The cooperation of close button, so switch key can expanding-contracting action, actuator is opened.
Further, the limiting component include pressing piece, the extensible member matched with the pressing piece and be set to pressing piece
On contradictory piece;The position that the position of pressing piece corresponds to button is arranged, and it is i.e. controllable flexible to carry out pressing operation to pressing piece
Part is flexible, and then realizes the flexible of pressing piece.
Further, the switch key connection one makes actuator be in power-off shape for the switch key to be reset to
The return unit of state;When unclamping the pressing to switch key, return unit is that may make switch key quickly leaves to open actuator
Position guarantees the fast break of actuator.
Further, described first connecting portion part includes driving member and first connector connected with the driving member;Pass through
The setting of driving member realizes the steering to power output direction, so that the outbound course of power can be connect with the second of actuator
Certain angle is generated between part, to adapt to different cutting modes for the demand in power output direction, meets a tractor serves several purposes
The case where;First connector have certain length, compared to by using umbrella tooth directly with driving device cooperate the case where and
Speech, the first connector and driving device have bigger adapted space, and then the cooperation of the two is more stable, are less prone to event
Barrier.
Further, the second connecting portion part includes having the driving member of umbrella tooth structure and cooperating with the driving member rotation stop
The second connector;Using the second connector to cutter device output power, the feelings that power output is directly carried out by umbrella tooth are compared
For condition, the cooperation between the second connector and cutter device is more stable, and failure rate is low;Driving member and the second connector are point
Body setting, machine-shaping are relatively easy on hand, reduce production difficulty;And when component damages, driving member and the second connection
Part can be replaced individually, and maintenance cost is low;Good rotation stop is realized between the two, and driving member and the second connector is effectively avoided to go out
The case where now skidding guarantees the stable drive of the two;Umbrella tooth structure and driving member realize engaged transmission, are directly realized by power side
To change, and control it is more flexible, steering angle floatability is bigger;Secondly, for compared to the transmission of flat tooth, stability
By force, the case where being less prone to derailing or skidding, failure rate is low.
Further, the driving device includes shell and the actuator in shell, is set on first connector
There is the grafting chamber matched with the actuator;By mating realization rotation stop between first connector and driving device, in turn
Rotation stop can be realized when cutter device is installed to driving device, without carrying out excessive cumbersome operation, power and energy speed
Fastly.
Further, circumferentially spaced on second connector to have multiple output gears;By way of tooth engagement
It realizes the power transmission between the second connector and cutter head, is not easy to skid, transmission effect is good.
Further, second connector is equipped with an at least notch;By the setting of notch, so that output section and knife
Rotation stop is realized by abnormity cooperation between head, it is easy to process, convenient for molding.
In conclusion the utility model has the advantage that limiting component can effectively limit actuator and be maintained at closing shape
The case where state is not in error starting prevents from hurting, safer;Cutter device can be replaced, and realize a tractor serves several purposes, warp
Ji material benefit, it is easy to carry;By the transmission cooperation between first connecting portion part and second connecting portion part, realize defeated to driving device
The gearshift adjustment of power out realizes driving of the same driving device to the cutter head of a variety of different structures, revolving speed, use scope
Extensively.
