Abstract
The utility model aims to provide a long reach chain saw which is convenient to operate. The long reach chain saw provided by the utility model comprises a long barrel rod, a handle, a static blade, a movable blade, a returning spring and a pull rod, wherein the static blade is fixed at one end of the long barrel rod, the handle is hinged to the other end of the long barrel rod, and the movable blade is hinged to and matched with the static blade through a pin shaft; one end of the returning spring is connected with the long barrel rod, and the other end of the returning spring is connected with the handle or the movable blade; the long reach chain saw has the keys that the pull rod penetrates through the long barrel rod, and the two ends of the pull rod are respectively connected with the handle and the movable blade through flexible cables. The long reach chain saw provided by the utility model has a simple structure, is convenient to operate, labor-saving, low in cost and long in service life, and has good market efficiency.
Description
Technical field
The utility model belongs to agricultural apparatus field, is specifically related to a kind of averruncator.
Background technology
For convenience of operation, people utilize averruncator to prune the branch of eminence.The utility model that application number is 201220149157 provides a kind of averruncator, this averruncator comprises fixed blade and knife section, on fixed blade, be fixed with fixedly fixture block, on knife section, be provided with movable clip block, described movable clip block is hinged on fixed blade and the hinged bearing pin of knife section by contiguous block, between described contiguous block and the afterbody of knife section, be provided with torsion spring, horizontal sawtooth shape fin is set respectively on the end face that fixedly fixture block is relative with movable clip block, zigzag fin cross section is for falling zigzag.Although this averruncator can be realized the pruning to eminence branch, but owing to only adopting the hard pull bar that is arranged in long cylinder bar to be connected between handgrip and knife section, like this in pruning process, when the rotational angle of handgrip or knife section is larger, pull bar will rock larger, thereby interfere impact operation with the inwall of long cylinder bar.And if address the above problem and increase a long cylinder shank diameter, also can cause that weight increases, the problem of inconvenient operation.
Summary of the invention
The purpose of this utility model is to propose a kind of easy to operate averruncator.
Averruncator of the present utility model comprises long cylinder bar, handle, fixed blade, knife section, back-moving spring and pull bar, described fixed blade is fixed on one end of long cylinder bar, described handle is articulated with the other end of long cylinder bar, and described knife section coordinates by bearing pin and fixed blade are hinged; One end of described back-moving spring is connected with long cylinder bar, and the other end is connected with handle or knife section; Key is that described pull bar is through long cylinder bar, and the two ends of pull bar are connected with handle, knife section respectively by flexible cable.
Pull handle, can drive knife section to move by flexible cable, pull bar, realize the pruning to branch under the cooperation of fixed blade, back-moving spring can help handle to reset, and is convenient to follow-up pruning operation.Because the two ends of pull bar are connected with flexible cable, therefore when the rotational angle of handle or knife section is larger, flexible cable can change shape, between pull bar and handle or knife section, form a transition, avoid pull bar because rocking compared with interfering with the inwall of long cylinder bar greatly, thereby guarantee the convenience of operation.
Further, described flexible cable is chain, and chain intensity is higher, can bear larger pulling force, and averruncator can, to pruning compared with fat tree branch, have been expanded its scope of application, and extend the service life of averruncator.
Further, described fixed blade, knife section are that bending direction is towards the arcuate structure of handle orientations, like this in pruning process, utilize fixed blade, knife section clamp branch and pull to handle orientations, not only be convenient to prune, can also control the position that branch drops, while avoiding branch to drop, smash the flowers and fruits of lower.
High branch shears structure of the present utility model is simple, easy to operate, cost is low, and long service life has good market efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of averruncator of the present utility model.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in Figure 1, the averruncator of the present embodiment comprises long cylinder bar 1, handle 2, fixed blade 3, knife section 4, back-moving spring 5 and pull bar 6, described fixed blade 3 is fixed on one end of long cylinder bar 1, described handle 2 is articulated with the other end of long cylinder bar 1, and described knife section 4 coordinates with fixed blade 3 is hinged by bearing pin; One end of described back-moving spring 5 is connected with long cylinder bar 1, and the other end is connected with knife section 4; Key is that described pull bar 6 is through long cylinder bar 1, and the two ends of pull bar 6 are exposed to long cylinder bar 1, and are connected with handle 2, knife section 4 respectively by bicycle chain 7.
Fixed blade 3, knife section 4 are that bending direction is towards the arcuate structure of handle 2 directions, like this in pruning process, utilize fixed blade 3, knife section 4 clamp branch and pull to handle 2 directions, not only be convenient to prune, can also control the position that branch drops, while avoiding branch to drop, smash the flowers and fruits of lower.
Pull handle 2, can drive knife section 4 actions by bicycle chain 7, pull bar 6, realize the pruning to branch under the cooperation of fixed blade 3, back-moving spring 5 can help handle 2 to reset, and is convenient to follow-up pruning operation.Because the two ends of pull bar 6 are connected with bicycle chain 7, therefore when the rotational angle of handle 2 or knife section 4 is larger, bicycle chain 7 can change shape, between pull bar 6 and handle 2 or knife section 4, form a transition, avoid pull bar 6 because rocking compared with interfering with the inwall of long cylinder bar 1 greatly, thereby guarantee the convenience of operation.
