Abstract

The high branch shears with adjustable angle has fixed and movable shearing blades in the upper end of casing-shaped shearing arm, and toothed shaft sleeve with adjustable angle in the lower end and meshed with the toothed shaft head and locked with screw nut. The force arm of the movable shear blade is provided with a balance weight and a spring. The high branch shears can adapt to the angle adjustment needed by the picking shears, overcome the defects that the existing shears are labor-consuming, time-consuming and easy to be hindered by branches, and greatly improve the picking and pruning efficiency.

Description

A kind of averruncator of adjustable angle

A kind of averruncator of adjustable angle, it relates to the special-purpose hand-held cutting element of gardening.

Be used for pruning ornamental trees and shrubs at present and pluck the scissors that fruit uses, generally be utilize long waddy or bamboo bar in termination crosswise fixed one scissors, its one cuts handle and is fixed on the bar, another is cut handle and then is held in the hand operation with the rope connection, in order to make scissors open utilization, moving shear blade is cut handle weight or is cut in the west and installs a torsion spring between handle additional, but this structure exists more weak point.Because laterally volume is big, easily collide branch and fruit in the use.Particularly the picking season is more outstanding during crops such as the harvesting tree betel nut that bar is higher, fruit is more, lichee, Liu Ding.Some position in pruning trees since scissors can not adjusting angle when the tree bar is higher, even cause and can't finish this difficult problem.

It is short that the purpose of this utility model provides a kind of shearing position, and the force part is long, and mechanical advantage is big, rope utilizes pulley, adjustable-angle, scissors easy to use solves the deficiency of prior art, and uprightly fixedly solve the obstruction of avoiding branch when stretching improves the pruning picking efficiency to scissors.

The utility model is realized in the following way, cutting the arm upper end at hull shape has the snip of deciding, lower end that a band tooth axle sleeve is arranged, and left-hand end is engaged on the band tooth spindle nose, right-hand end penetrates a tie down screw, and passes band tooth axle sleeve and be with the tooth spindle nose to be tightened in the locking nut.It is a bar cover that the handle lower end is cut in adjustment, and its right-hand end has the bracing frame of a band roller, and bar is cut in the interior intercalation of bar cover fixedly height.Hull shape is cut the arm top surely, articulates active cutter plate with pivot, and the moving of active cutter plate cut on the handle, fixes a counter-balanced carriage of cutting of a band roller, and extension spring one end is through to be decided on the snip hole.The other end is buckled on to be cut on the counter-balanced carriage spring eye.Rope one end is fixed on hull shape and cuts surely in the arm, and the other end is worn around roller and decided roller, cuts the sagging paramount bar bottom of cutting of bar along height.

This utility model has the following advantages:

1, it utilizes the locking nut adjustable angle, adapts to the shearing harvesting work of different angles and direction.Its scissors is vertically fixing, has reduced trees stalk wooden fork and has hindered.

2, scissors application of force brachium, to shear the position short, thereby mechanical advantage is big, and is laborsaving in the shearing work, save time the efficient height.

Description of drawings:

Accompanying drawing 1, the utility model axonometric exploded view

Accompanying drawing 2, the utility model stereogram

Below by accompanying drawing the utility model embodiment is described further.Cut arm 13 upper ends at hull shape and be shaped on and decide snip 12, there is a disjunctor half round post its lower end, the band tooth axle sleeve 21 of cover shape position block 211, and it utilizes engaging tooth 26 and engaging tooth 261, is engaged on the arcuation tooth 25 and arcuation tooth 251 on the band tooth spindle nose 22.Band tooth axle sleeve right side penetrates a tie down screw 60 and passes band tooth axle sleeve 21, and band tooth spindle nose 22 is tightened in the locking nut 40.The as a whole bar cover 27 in handle 20 lower ends is cut in adjustment.A bracing frame 28 is stretched out on its right side, adorns a roller 24 with pivot 29 pivots on the frame.A high bar 50 of cutting is fixed in intercalation in the endoporus of bar cover 27.Hull shape is cut arm 13 surely and is articulated an active cutter plate 11 near tops with pivots 121, active cutter plate moving cut fix on the handle 111 one have a roller 31 cut arm counter-balanced carriage 30.Open extension spring 32 1 ends of active cutter plate are buckled on the hole 122 of deciding snip 12, and the other end is buckled on to be cut joining on the frame spring eye 33.Rope one end is fixed on hull shape and cuts surely in the arm 13, and the other end is worn around roller 31 and decided roller 24, cuts bar 50 along height and hangs down into the bottom that height is cut the bar total length.Pluck or pruning in when needing to adjust angle, need only be with locking nut, unscrew, be threaded to and can transfer to required angle after engaging tooth leaves mutually, again locking nut is screwed, scissors is engaged on the reposition.
