When the insulating telescopic rod is extended or shortened, the length of the stay wire 4 in the insulating telescopic rod can be correspondingly changed through the wire take-up assembly. The specific operation is as follows: the threaded rod 23 is rotated to enable the threaded rod 23 to move downwards and press the pawl, the pawl 21 rotates under the action of the threaded rod 23 to be separated from the clamping groove of the ratchet wheel 20, and at the moment, the rotating shaft 24 is rotated through the handle, so that the take-up pulley 19 can pay out or take up. After the length of the insulating telescopic rod is adjusted, the redundant stay wire 4 is wound on the take-up pulley 19, the pawl 21 is clamped in the clamping groove of the ratchet wheel 20 under the action of the torsion spring 26 to position the take-up pulley 19, and the phenomenon that the stay wire 4 is overlong and knotted due to the fact that the take-up pulley 19 rotates to pay off or the stay wire 4 is tensioned and broken due to the fact that the stay wire rotates to take up is avoided.
And a first steering wheel and a second steering wheel which are used for steering the stay wire 4 are arranged on the insulating telescopic rod. The arrangement of the first steering wheel and the second steering wheel can prevent the stay wire 4 from contacting with edges and corners inside the parts, so that the stay wire 4 is prevented from being cut off by the edges and corners.
The other connecting shaft 12 penetrates through the trimming shell 8 and is connected with a positioning assembly, the positioning assembly comprises a positioning round table 27 connected to the connecting shaft 12 and a positioning ring 28 arranged on the outer side of the positioning round table 27, the positioning ring 28 is connected with the trimming shell 8 through a second spring 29 sleeved outside the connecting shaft 12, and an inner conical surface matched with the positioning round table 27 is arranged on the positioning ring 28.
A third steering wheel for steering the connecting wire 5 is arranged in the connecting sleeve 1, and a fourth steering wheel for steering the connecting wire 5 is arranged in the trimming shell 8. The action of the third steering wheel and the fourth steering wheel is similar to that of the first steering wheel and the second steering wheel, so that the connecting line 5 can be prevented from being broken by edges and corners.
The present embodiment further comprises a saw blade 30, the saw blade 30 and the trimming shell 8 are correspondingly provided with a connecting hole, and the saw blade 30 is connected to the trimming shell 8 through a connecting bolt 31 arranged in the connecting hole.
The working principle is as follows: when pruning is carried out, the fixed cutter head 10 and the movable cutter head 11 are utilized to clamp branches to be pruned, then the stay wire 4 is pulled (the force application point is on the stay wire 4 between the steering wheel II and the take-up pulley 19), at the moment, the stay wire 4 drives the slide block 2 to move downwards by overcoming the elasticity of the spring I7, the slide block 2 drives the connecting wire wheel 9 to rotate through the connecting wire 5, and therefore the movable cutter head 11 rotates towards the direction of the fixed cutter head 10 and cuts off the branches; after the branches are cut off, the pull wire is loosened, the sliding block is reset under the action of the spring I, and the movable cutter head and the fixed cutter head are opened again; when the branches are thick and cannot be trimmed by the fixed cutter head 10 and the movable cutter head 11, the branches can be sawn off by the saw blade 30. In this embodiment, prune the shell and connect the 1 normal running fit of connecting sleeve on insulating telescopic link, this kind of setting can in time adjust the angle of moving tool bit and stationary knife head according to the position of branch, need not staff's transform operating position and can realize the pruning to all directions branch, the work load that has significantly reduced has reduced intensity of labour, and labour saving and time saving has improved work efficiency. Because the connecting wire 5 penetrates into the connecting sleeve 1 from the connecting shaft 12, and the pull wire 4 penetrates through the insulating telescopic rod and is connected to the wire collecting assembly, the angle adjustment of the trimming shell 8 cannot influence the rotation of the movable cutter head, and the normal operation of cutting branches can be ensured. The wire take-up component can take up and pay off the stay wire 4 according to the length of the telescopic insulating rod. The saw blade 30 is connected to the trimming shell 8, so that the angle adjustment can be realized, and the sawing of branches in different directions and positions can be realized.
Connecting sleeve 1 can be dismantled through threaded sleeve 18 and connect on insulating telescopic link, and saw bit 30 can be dismantled through connecting bolt 31 and connect on pruning shell 8, and the change of the scrapped back of this kind of setting not only is convenient for wear and tear move tool bit, stationary knife head and saw bit 30, is convenient for accomodate when not using moreover, saves, conveniently carries, has improved the convenience.
Under the action of the second spring 29, the inner conical surface of the positioning ring 28 in the positioning assembly abuts against the positioning circular truncated cone 27, so that the connecting shaft 12 can be positioned, the rotation of the trimming shell 8 caused by improper operation of an operator or external force influence in the use process is avoided, the stability of the trimming assembly is ensured, and the deviation of the trimming assembly is avoided. When the angle of the trimming shell 8 needs to be adjusted, the positioning ring 28 is pressed towards the trimming shell 8, the positioning circular truncated cone 27 is separated from the inner conical surface of the positioning ring 28, the connecting shaft 12 is rotated, and after the adjustment is completed, the positioning ring is released, so that the positioning circular truncated cone is abutted to the inner conical surface of the positioning ring again.
According to the invention, through the matching of the trimming component and the wire collecting component, the trimming and sawing of branches at different positions can be realized, the use is convenient, the workload is greatly reduced, and the working efficiency is improved.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the illustrated embodiments.
