Description

A kind of Novel tree-pruner

Technical field

Clipping device technical field is the utility model is related to, especially a kind of Novel tree-pruner.

Background technology

In urban afforestation at present and the construction in park, it is often necessary to plant tall trees wood, with beautifying city and park, carry The oxygen source enriched for people.And these tall trees wood are being trimmed, it is necessary to which using averruncator, in general averruncator uses Two blades of relative motion carry out shear action, and a blade is fixed in structure, and another blade is rotation, generally Guide rotating blade to be sheared using drawstring, rotating blade return is caused using spring, facilitates next shearing manipulation.

In the averruncator of this structure, the arm of force of drawstring is generally less than the arm of force of rotating blade, more laborious during operation； If increasing the arm of force of drawstring, overall structure easily causes body of rod stress deformation again.

Utility model content

The utility model in view of the shortcomings of the prior art, proposes a kind of Novel tree-pruner, simple in construction, easy to operate.

In order to realize above-mentioned purpose of utility model, the utility model provides following technical scheme：A kind of Novel tree-pruner, bag The body of rod and drawstring, in addition to hook, motion bar, chain knife and spring are included, it is described to link up with the top for being fixed on the body of rod, the extension Hook side is provided with gear；On one end bearing pin of the motion bar is connected in the middle part of the hook, described chain knife one end and the work The other end of lever is hinged, and the other end is connected around the gear with the drawstring；The spring be connected to the motion bar and Between the bottom of the hook.

Preferably, the medial surface of the hook is set to cutting edge shape.

Preferably, the body of rod is expansion link.

Preferably, the hook is to be threadedly coupled with the body of rod.

So-called chain knife, it is to tie in each chain of chain and add blade.

Compared with prior art, the utility model has advantages below：Coordinated using chain knife and motion bar, drawn by drawstring Draw chain knife to carry out sawing to branches of tall trees and reach shear effect；Overall structure is simple, easy to operate, cost is low, and effect is good, makes Use long lifespan.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model Novel tree-pruner；

Diagram mark：1 body of rod, 2 drawstrings, 3 hooks, 4 motion bars, 5 chain knives, 6 springs, 31 gears.

Embodiment

The utility model is described in detail below in conjunction with the accompanying drawings, the description of this part be only it is exemplary and explanatory, There should not be any restriction effect to the scope of protection of the utility model.

As shown in figure 1, a kind of Novel tree-pruner, including the body of rod 1 and drawstring 2, in addition to hook 3, motion bar 4, the and of chain knife 5 Spring 6, the hook 3 are fixed on the top of the body of rod 1, and 3 sides of the hook are provided with gear 31；The one of the motion bar 4 End bearing pin is connected on the middle part of hook 3, and described one end of chain knife 5 and the other end of the motion bar 4 are hinged, and the other end bypasses The gear 31 is connected with the drawstring 2；The spring 6 is connected between the bottom of the motion bar 4 and the hook 3.

When in use, hook 3 is hooked on the branch for needing to cut, and pulls drawstring 2, and chain knife 5 can be tightened and touch branch Bottom, continue drawstring 2 of leaving behind, motion bar 4 rotates around bearing pin, and chain knife 5 can be along branch basal sliding, so as to be sawed to branch Cut；When loosening drawstring 2, under the active force of spring 6, chain knife 5 can be retracted；Aforesaid operations are repeated, branch can be cut up.

The arch section medial surface of the hook 3 is set to cutting edge shape, in the presence of chain knife 5, can be cut on the upside of branch Cut, branch is sheared respectively from upper and lower both sides, accelerate the speed of shearing.

Position according to where branch is different, the body of rod 1 can be set to Telescopic rod structure, operation and carrying are all very just Profit.

Carried to easily facilitate, will can be set to be threadedly coupled between the hook 3 and the body of rod 1, be carried out before use Assembling.

This averruncator relative to traditional cut mode structure, using sawing mode, rapid operation, the use to averruncator Life-span can be improved effect.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
