Abstract

The utility model discloses a labor-saving high-branch trimmer comprising a support rod, a fixed blade and a movable blade. The tail end of the fixed blade is fixedly connected with the support rod, the fixed blade and the movable blade are hinged through a rotary shaft, a reset spring is arranged between the fixed blade and the movable blade, a cutting bit of the fixed blade is provided with a hook ring, and a plurality of clamp grooves are arranged in the cutting edge of the fixed blade; the cutting edge of the movable blade is provided with a plurality of projections corresponding to the clamp grooves. The labor-saving high-branch trimmer further comprises a pedal, one end of the pedal is hinged to the lower portion of the support rod, the other end of the pedal is connected with a pulling rope, and the other end of the pulling rope is fixed at the tail end of the movable blade. When the labor-saving high-branch trimmer is used for trimming branches, twigs are disposed at a smooth section of the fixed blade, then a user only needs to hold the support rod with both hands and step on the pedal; for boughs, the boughs are disposed in the clamp grooves, the user only needs to step on the pedal and the boughs then can be easily trimmed under the action of the projections. The labor-saving high-branch trimmer is simple in structure and capable of easily trimming the branches.

Description

A kind of Labour-saving tree pruner

Technical field

The utility model belongs to tree pruner of garden field, is specifically related to a kind of Labour-saving tree pruner.

Background technology

In the process of gardens pruning branch, existingly mainly contain following several mode: 1, under the help of ladder, close on branch and prune, this kind of mode is more dangerous, and wastes time and energy; 2, use averruncator, under the pulling of stay cord, branch is cut off, this kind of form had widely in existing pruning process to be used, but existing high altitude scissors is that a stay cord pulls cutter head, thereby cuts off branch.Pull with hand in the process of stay cord, also want on the other hand hand-held high altitude scissors handle, easily cause firmly deficiency, cause branch to be cut off.And branch easily slides in the process of cutting, cause efficiency lower.

Utility model content

The utility model aims to provide a kind of simple in structure, Labour-saving tree pruner that result of use is good.

For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of Labour-saving tree pruner, comprise pole, fixed blade and movable blades, fixed blade tail end is fixedly connected with pole, fixed blade and movable blades are hinged by rotating shaft, between fixed blade and movable blades, be provided with back-moving spring, the cutter head end of described fixed blade is provided with hook ring, and its blade is provided with several draw-in grooves; The blade of described movable blades is provided with several projections corresponding with draw-in groove on fixed blade; Described averruncator also comprises pedal, and one end of pedal is hingedly mounted on pole bottom, and the other end of pedal is connected with stay cord, and the other end of stay cord is fixed on the tail end of movable blades.

Described pedal top, a club shaft are provided with at least two trepannings, and stay cord is drawn and through after trepanning, is fixed on movable blades tail end successively again from pedal.

Described pedal upper surface is matsurface.

Described draw-in groove is circular-arc, and described draw-in groove and protruding material are carbide alloy.

Described pole is telescopic rod.

The beneficial effects of the utility model are: 1, by the cutter head end at fixed blade, hook ring is set, thereby under too high branch is hooked, conveniently cuts off; 2, at the blade of fixed blade, establish draw-in groove, the blade correspondence of movable blades arranges projection, thereby while running into the thicker situation of branch, can in draw-in groove, to it, cut off, and has avoided branch in the process of cutting to slide; 3, the material selection carbide alloy of draw-in groove and projection, thus its wearability increased; 4, pedal is set, thereby has avoided pulling moving stay cord, make both hands can hold pole, more easily exert oneself; 5, one end of pedal is hingedly mounted on pole bottom, thereby has avoided pedal to rock back and forth; 6, pedal upper surface is matsurface, thereby avoided cutting off in the process of branch, skidding occurs; 7, stay cord is drawn and through after trepanning, is fixed on movable blades tail end successively again from pedal, prevents that, in the process of work, the foreign material such as branch disturb stay cord and movable blades; 8, pole is set to telescopic rod, makes this device be applicable to the branch of differing heights, has widened the scope of application of installing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

A kind of Labour-saving tree pruner as shown in Figure 1, comprise pole 6, described pole 6 is telescopic rod, the scalable interior bar that can be threaded connection by setting and the outer bar of pole 6 are realized, according to branch height of living in, interior bar is back-outed or is screwed into, thereby branch is removed, on interior bar, be fixed with fixed blade 1, fixed blade 1 cutter head end arranges hook ring 10, thereby when branch is higher, hooked down and cut off, fixed blade 1 blade is provided with several draw-in grooves 8, draw-in groove 8 inner surfaces are circular-arc, material is carbide alloy, corresponding draw-in groove 8 is provided with circular-arc projection 9, when running into branch when thicker, while cutting off, easily there is sliding phenomenon on level and smooth blade, now branch can be placed in to draw-in groove 8, circular-arc draw-in groove 8 more easily adapts to the branch of different size, under the effect of projection 9 and draw-in groove 8, can fast branch be cut off, adopt carbide alloy material also make projection 9 and draw-in groove 8 more wear-resisting.Projection 9 is located at movable blades 2 blades, and movable blades 2 is hinged by rotating shaft with fixed blade 1, is provided with back-moving spring 7 between fixed blade and movable blades, and back-moving spring 7 plays the effect of reset, thereby after cutting off branch, special operations blade 2 Rapid resets.On described averruncator, be also provided with pedal 4, pedal 4 upper surfaces are matsurface, thereby avoid skidding in cutting off the process of branch, one end of pedal 4 is hingedly mounted on pole 6 bottoms, by pedal 4 and pole 6 is hinged, avoided pedal in the course of work to shake, the other end of pedal 4 is connected with stay cord 3, the other end of stay cord 3 is fixed on the tail end of movable blades 2, pedal 4 tops, pole 6 bodies of rod are provided with two trepannings 5, stay cord 3 is drawn and through after two trepannings 5, is fixed on movable blades 2 tail ends successively again from pedal 4, by stay cord 3 is arranged in trepanning 5, prevent that the foreign material such as branch from causing interference to stay cord, in the time need to carrying out the removing of branch, only need will ride on pedal 4, and pedal downwards, thereby more easily branch is cut off and the balance of holding device.

In cutting off the process of branch, thinner branch can be placed in the smooth section of fixed blade 1, and held by both hands pole 6, with riding pedal 4; When branch is thicker, branch can be placed in to draw-in groove 8, step on pedal 4, under the effect of projection 9, easily branch is cut off, when branch is higher, utilize the hook ring 10 of fixed blade cutter head end, after under branch hook, cut off again.

The Labour-saving tree pruner that the utility model provides is simple in structure, branch can be cut off easily, has stronger service life.
