Description

Branches of tall trees hedgeclipper working head angle regulator

Technical field

The utility model relates to a kind of garden trimming machine tool, especially the branches of tall trees hedgeclipper working head angle regulator in the garden trimming machine tool.

Background technology

The branches of tall trees hedgeclipper is used for the trees lopping, prunes the pruning than high fruit tree of higher big ornamental trees and shrubs or broadband hedgerow and orchard.This branches of tall trees hedgeclipper generally includes casing, is located at the gear of gasoline engine drive installation on main shaft in the casing through the transmission mechanism outputting power, realizes that the pruning shear that stretches out in casing prunes operation.Some small-sized hand-operated, electronic shrub and hedge trimmer often have angle adjusting mechanism, for example be called " the automatic hedge clipper of handled easily " for CN201479646U, name by Patent Office of State Intellectual Property Office Granted publication number, in its disclosed technical scheme, comprise two scissors, handle, pruning transmission mechanism, angle adjusting mechanism, the pruning motor, the angular adjustment motor is installed on pruning switch on the handle and angular adjustment switch etc.By pruning switch and the angular adjustment switch on the operation handle, be transmitted in the rotational circle wheel that is installed in handle upper end and fix on the runing rest on it, because two scissors are hubbed on the runing rest by rotating shaft, make two scissors relatively rotate the formation shearing relation around the shaft.This structure more complicated will be controlled respectively with two motors, and cost is improved relatively.Hedgeclipper commonly used there is no the angle adjusting mechanism setting, and the operator can only come the map function angle according to the object of being pruned in actual use, and the operator requires great effort very much, and is also very inconvenient, particularly prunes those sturdy branches, often needs bigger power; Remove this, because the object shapes difference of being pruned only depends on the operator to alter one's posture, one to prune effect undesirable, two operate hard.

Summary of the invention

Goal of the invention of the present utility model is to overcome the defective of prior art, the branches of tall trees hedgeclipper working head angle regulator of the optimal comfort state when proposing a kind of simple in structure, easy to operate, operator and can find the adjusting angle that self needs to determine to prune at any time, thereby improve the validity and the flatness of pruning, reach very good pruning effect.

Goal of the invention of the present utility model is achieved through the following technical solutions:

A kind of branches of tall trees hedgeclipper working head angle regulator, it comprises casing, and engine, main shaft and transmission mechanism are installed in the casing, and handle is installed on the casing, it is characterized in that described casing is provided with the fixing arc check plate of obvolvent, is distributed with a plurality of adjustment holes on this arc check plate; Be provided with the gear box B of rotating around main shaft in the described casing relative to casing, be provided with the flexible handle sleeve of relative gear box B in this gear box B outer end, the gear box B endoporus is provided with the pin that can plug with arc check plate adjustment hole, this pin is set with spring and connects the handle sleeve, and described spring is located at the nut that is connected with gear box B and snaps onto between the jump ring on the pin.

Adjustment hole on the described arc check plate is the five equilibrium setting.

Described pin is connected with the integrated through injection molding that is connected to of handle sleeve.

Described gear box B is provided with bearing relative to the faying face that casing rotates.

Compared with prior art, the utility model has been done improvement on forming the casing of working head, the basis of engine, main shaft and transmission mechanism in the casing, on casing, set up arc check plate and gear box B, telescopic handle sleeve is set in the gear box B outer end, the pin that can plug the location with arc check plate adjustment hole is set in the gear box B.Product after the improvement, as long as the operator is just can be according to the object shapes different adjustment map function angle of being pruned by shirtsleeve operation, reach and working head angular adjustment purpose, obtain very good pruning effect, this project organization is simple, easy and simple to handle laborsaving, need not to increase power source, with low cost.

Embodiment

Below with reference to above-mentioned accompanying drawing the utility model embodiment is described in detail again.

Shown in Fig. 1～4, branches of tall trees hedgeclipper working head angle regulator, it comprises casing 4, be provided with engine in the casing, engine is realized speed change output by main shaft 11 through transmission mechanism, realizes pruning operation thereby drive pruning shear, and above-mentioned part constitutes the working head of hedgeclipper.Control crank when being installed in handle 8 on the casing and being the GREEB HEDGE MACHINE pruning trees.

In order to prune bigger trees, the operator can be according to being come the map function angle by the plant for pruning position, reach comfortable manipulation purpose, the utility model has designed the device that relative working head can be made angular adjustment, this device is provided with the fixing arc check plate 1 of obvolvent on the one hand on former casing 4, this arc check plate is semi-annular shape, covers administration of fixed on the casing, the arc check plate is provided with the adjustment hole 9 that five equilibrium distributes, and realizes many grades of angular adjustment; The gear box B 7 that can rotate around main shaft 11 relative to casing is set in casing 4 on the other hand, both adopt, and axis hole is movable to be cooperated, in order to rotate flexibly, on the faying face of gear box B and casing, be provided with bearing 12, this bearing comprises in both, cylindrical faying face and plane faying face all have setting, simultaneously, this gear box B outer end is provided with telescopic relatively handle sleeve 5, pass the nut 6 that is connected in the gear box B 7 with the pin 2 of handle sleeve integrated through injection molding, front end can be pegged graft with the adjustment hole 9 on the arc check plate 1, be set with spring 3 on the pin, this spring is located at described nut 6 and snaps onto between the jump ring 10 on the pin 2, so pin is provided with the jump ring groove of preprocessing, nut 6 has played the flexible guide effect of pin.The pin that will connect during assembling on the handle sleeve overlaps top nut, spring and jump ring successively, and the gear box B of packing into endoporus screws nut then with being connected of gear box B, and nut and handle sleeve do not have annexation.The flexible connection of handle sleeve 5 relative gear box B 7 also realizes by pin 2.

When people operate pruning trees, arrest handle 8 on the other hand, arrest handle sleeve 5 on the other hand.When the needs adjusting angle, control handle sleeve 5 is pulled out pin 2, spring 3 energy storage this moment, pulling handle sleeve driven gear case B7 rotates an angle together then, when needs are aimed at another adjustment hole 9, loosens handle sleeve 5, pin 2 spring 3 release can act under pushing tow jump ring 10, pin 2 just enters another adjustment hole 9, runs into to take in the gear box B promptly to be placed restrictions on putting in place to jump ring, reaches working head angular adjustment purpose.
