Abstract

The utility model discloses a pair of pole pruning scissors which comprises movable scissors and fixed scissors which can be engaged with each other, wherein the movable scissors and the fixed scissors are respectively connected with a movable force-adding piece and a fixed force-adding piece which are hinged together, a guiding frame and a supporting pipe connected between the fixed scissors and the fixed force-adding piece, and the movable scissors is hinged with the movable force-adding piece through the guiding frame and the supporting pipe. The pole pruning scissors has the advantages of large scissoring force and high pruning efficiency, and is designed according to the principle of force and a force arm so that the force-adding pieces are lengthened, the scissoring force is enlarged, and the utility model can scissor tree branches growing for many years; through testing, the pole pruning scissors can scissor off common steel bars so as to be convenient for pruning operation; the supporting pipes and the force-transfer connecting rod of the pole pruning scissors are in a multi-node tapping type, and therefore, the pole pruning scissors can reach to high or short branches without the help of other tools, such as ladders, etc., so as to have safety.

Description

The stock shrub and hedge trimmer

Technical field: the utility model relates to a kind of power tool, relates in particular to the stock shrub and hedge trimmer of long shoot trees such as a kind of gardens fruit tree, Hua Shu.

Background technology: shrub and hedge trimmer are one of a kind of important tool that are used for the gardens operation, pruning for the arbor of shorter seeds such as holly and so on, the special-purpose shrub and hedge trimmer that use long handle both can, prune handle length that long handle then cuts for the fruit tree of some long tree bars or flower branch bar and be difficult to arrive and pruned branch; At present, most gardener uses a kind of stock shrub and hedge trimmer that are similar to the long handle shear structure, one of this shrub and hedge trimmer cuts the handle bending, vertically part and a long bamboo bar are connected, and another moves cuts force application handle and be connected with a steel wire or rope, during beta pruning, two shearing blades by spring pulling open, by spurring the rope closure, this shrub and hedge trimmer are simple in structure, and cost is low, make easily, but have following shortcoming, 1, use restricted; As calculated, this shrub and hedge trimmer are 350 kilograms to branch maximum shear stress (is 50 kilograms by the human arm lower pulling force); Powerless when pruning big branch for need; 2, laterally moving cutting edge and add about 300 millimeters of arm of force length overall, therefore when stretching to, often be subjected to keeping branch and stop, also need height when pruning by ladder for the branch of tall and big trunk by poll and pulling cord, thereby influence the raising of operating efficiency, and exist hidden danger.

Summary of the invention: exist big branch in the pruning of tree and be difficult for cutting off and prune inefficient shortcoming in order to solve the gardens fruit tree or to view and admire, the purpose of this utility model provides a kind of pruning fruit trees and views and admires branch bar efficient height, simple to operate, flexible, safety and use stock shrub and hedge trimmer widely.

The technical solution of the utility model realizes in the following manner:

A kind of stock shrub and hedge trimmer, it comprises two snappable moving scissors, decides scissors, wherein moving scissors, decide scissors respectively with moving force-applying member, decide force-applying member and be connected, moving force-applying member, decide force-applying member and be articulated as one, decide scissors and decide to be connected with between the force-applying member guide housing, stay pipe, moving scissors is hinged by guide housing, stay pipe and moving force-applying member.

Also be connected with force transmitting link between moving scissors and the force-applying member, force transmitting link is hinged by stay pipe and moving force-applying member.

Stay pipe, force transmitting link are stay pipe, the force transmitting link of more piece tapping type.

Moving force-applying member with decide between the force-applying member by pin, prop up that to move brace hinged.

For increasing operator's arm power, force transmitting link can be the spline-simulating force transmitting link, and moving force-applying member termination has and spline-simulating force transmitting link meshed gears, also connects non-return claw on the moving force-applying member.

The force transmitting link tail end can be the spline-simulating force transmitting link.

On moving scissors, be equipped with and the moving cutting edge of deciding the shearing blade interlock.

For further increasing shearing force, directly be connected with hydraulic jack at the force transmitting link tail end.

Good effect of the present utility model is:

1, these shrub and hedge trimmer shearing force is big, prunes the efficient height, and these shrub and hedge trimmer design according to power and arm of force principle, force-applying member lengthening, shearing force are increased, can cut off the branch of life in 5 years, through test, these shrub and hedge trimmer can be cut off regular reinforcement, have brought convenience for the pruning operation.

2, these shrub and hedge trimmer stay pipe and force transmitting link are the more piece tapping type, thereby no matter the branch height, scissors can both arrive, and need not by other ladder and so on, thereby safety.

Description of drawings:

Fig. 1 is a perspective view of the present utility model.

Fig. 2 is the structural representation of force transmitting link and moving force-applying member tooth bar, gear-driven form.

Fig. 3 shows structural representation for Fig. 1 along cuing open of B-B direction.

Fig. 4 shows structural representation for Fig. 1 along cuing open of A-A direction.

Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1, Fig. 3, Fig. 4 as can be seen, the utility model comprises two snappable moving scissors 1, decides scissors 4, wherein moving scissors 1, decide scissors 4 respectively with moving force-applying member 9, decide force-applying member 10 and be connected, moving force-applying member 9, decide force-applying member 10 and be articulated as one, decide scissors 4 and decide to be connected with between the force-applying member 10 guide housing 14, decide to be connected with stay pipe 6 between force-applying member 10 and the guide housing 14, moving scissors 1 is by guide housing 14 and force transmitting link 5 welding, and force transmitting link is formed the moving arm mechanism of cutting from supporting to pass in 6 by pin 7 and moving force-applying member 9 are hinged;

Decide scissors 4 and the welding of stay pipe 6 front ends, the rear end of stay pipe 6 with decide force-applying member 10 and be welded to form and cut arm mechanism surely; Moving force-applying member 9 with decide between the force-applying member 10 by pin 7, prop up that to move brace 8 hinged, prop up the design that moves brace 8 and guaranteed that the folding rotation of force-applying member 9 makes force transmitting link 5 cut moving up and down of arm mechanism with moving, force transmitting link 5 and stay pipe 6 are stay pipe, the force transmitting link of more piece tapping type, guarantee the pruning to the height branch.

On moving scissors 1, be equipped with the moving cutting edge 2 of deciding shearing blade 3 interlocks so that turned phenomenon does not take place during the shear-steel muscle.

As seen from Figure 2: for increasing operator's arm power, force transmitting link 5 is spline-simulating boosting-rods 11, and moving force-applying member 9 terminations have and spline-simulating boosting-rod meshed gears 12, also connects non-return claw 13 on the moving force-applying member 9.

The utility model is held by operating personnel's both hands branch and to be decided the force-applying member end when manipulating, and terminal aperture is pushed into 90.Move during angle and decide the scissors extended distance more than 15 millimeters, will cut arm again and stretch to the branch that will cut, the branch that affirmation is cut is clipped in to move to be decided firmly to close up between the scissors, is just cut off by the beta pruning bar.
