Abstract

The utility model provides a tree pruner, comprising a fixed blade and a movable blade, wherein a fixed clamping block is fixed on the fixed blade, a movable clamping block is arranged on the movable blade and is hinged with a pin shaft through a connection block, the fixed blade and the movable blade are hinged with the pin shaft, a torsion spring is arranged between the connection block and the tail part of the movable blade, the opposite end surfaces of the fixed clamping block and the movable clamping block are respectively provided with a transverse sawtooth-shaped raised edge, and the cross section of each transverse sawtooth-shaped raised edge is inverted sawtooth-shaped. The tree pruner disclosed by the utility model can skillfully separate the operation of clamping tree branches from the operation of cutting the tree branches, so that the tree pruner is capable of cutting thicker tree branches and simultaneously can ensure that cut tree branches cannot randomly fall down to break tender tree branches, flowers and fruits when the tree pruner is used for cutting off high tree branches.

Description

A kind of averruncator

Technical field

The utility model relates to a planting fruit-trees, garden instrument, more particularly relates to the averruncator of a kind of pruning that is applicable to fruit tree, gardens, flower thinning, harvesting etc.

Background technology

At present, operations such as pruning, harvesting in the orchard, the instrument that generally uses is an averruncator; General averruncator all is made up of knife section, fixed blade, a long tube bar, pull bar, Top carry handle and assistant's handle, and this averruncator can only be accomplished the pruning operation of branches of tall trees, and; The disconnected branch that is pruned away is from setting nature; Blocked by crotch sometimes, in the process that drops, disconnected branch can damage delicate branches and leaves or damage flowers and fruits sometimes.Though there is a kind of averruncator on dynamic and static blade, to be fixed with fixture block; It is the thick branch of 6mm-7mm that this kind averruncator also can only be cut off diameter, and to thick slightly any branch, it is when shearing; Because fixedly fixture block is with the branch clamping; Anti-to the shearing that has hindered dynamic and static blade, so this averruncator only is applicable to cutting, repairing of general thin branch.

Summary of the invention

In order to solve the problems referred to above that exist in the prior art, the utility model provides a kind of pruning, flower thinning, harvesting that is applicable to fruit tree, gardens, and can shear the averruncator than the fat tree branch.

The utility model is realized through following technical scheme: a kind of averruncator; Comprise fixed blade and knife section; Be fixed with fixedly fixture block on the fixed blade; Knife section is provided with movable clip block, and said movable clip block is hinged on the hinged bearing pin of fixed blade and knife section through contiguous block, is provided with torsion spring between the afterbody of said contiguous block and knife section.

In the such scheme, not slippage when making said fixedly fixture block and movable clip block clamping branch is provided with horizontal sawtooth shape fin respectively on said fixedly fixture block and the movable clip block opposing end faces.

In the such scheme, said zigzag fin cross section is for falling zigzag.

The beneficial effect of the utility model averruncator is:

1, owing to fixedly be provided with the fin of falling the sawtooth on the opposite face of fixture block and movable clip block, during than the fat tree branch, branch is slippage forward not, more effectively cuts off branch in clamping.

2, be hinged on the bearing pin through contiguous block owing to movable clip block; So just make between movable clip block and the knife section buffering is arranged when knife section and fixed blade suit; In cutting off the process of branch, can guarantee that branch is held not slippage, can effectively branch be cut off again.

3, this averruncator structure is ingenious, easy to use, and the branch that suitable shearing is thicker also can guarantee simultaneously in the operation of shearing the eminence branch, and the branch of being cut off can arbitrarily not fall down and damage delicate branch and flowers and fruits.

Description of drawings

Fig. 1 is the structural representation of the utility model averruncator;

Fig. 2 is the rearview of scissors head among Fig. 1.

Among the figure: 1. pull bar, 2. pull bar steady pin, 3. fixed blade, 4. fixedly fixture block, the 5. fin of falling the sawtooth; 6. knife section, 7. movable clip block, 8. contiguous block, 9. bearing pin is 10. grown a bar; 11. Top carry handle, 12. handgrip torsion springs, 13. assistant's handles, 14. blocks; 15. locating slot, 16. blade torsion springs, 17. fixing holes, 18. locating holes.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model averruncator is done further to describe:

Fig. 1 is the structural representation of the firm averruncator of the utility model, and among the figure, fixed blade 3 and knife section 6 are hinged and can relatively rotate through bearing pin 9; Be fixed with fixedly fixture block 4 on the fixed blade 3, knife section 6 is provided with movable clip block 7, and movable clip block 7 is through the side of contiguous block 8 relative fixed at knife section 6; Fixedly fixture block 4 is circular-arc identical each other with movable clip block 7 opposing end faces, fixedly on fixture block 4 and movable clip block 7 opposing end faces horizontal sawtooth shape fin of falling the sawtooth 5 is set respectively, and the afterbody of fixed blade 3 is fixed on the upper end of long tube bar 10; The tail end of knife section 6 is connected with pull bar 1 through pull bar steady pin 2; The other end of pull bar 1 passes assistant that long tube bar 10 is connected long tube bar 10 lower ends on 13, assistant pass through bearing pin to 13 and Top carry handle 11 hinged, and can rotate around bearing pin; Assistant 13 and Top carry handle 11 between be provided with handgrip torsion spring 12; All the time give assistant 13 with 11 1 open power of Top carry handle, through revolute pair handgrip 13, drive the afterbody that pull bar 1 spurs knife section 6; Knife section 6 is rotated around bearing pin 9, make knife section 6 and fixed blade 3 do shear action.Assistant is provided with block 14 to 13, and Top carry handle 11 is provided with two locating slots 15, and block 14 is stuck in the different locating slot 15, the size of the subtended angle between controllable brake blade 6 and the fixed blade 3.

Fig. 2 is the rearview of scissors head among Fig. 1.Among the figure; Fixedly the contiguous block 8 of movable clip block 7 is hinged on the hinged bearing pin 9 of fixed blade 3 and knife section 6; Between the afterbody of contiguous block 8 and knife section 6, be provided with torsion spring 16; One end of torsion spring 16 is fixed in the locating hole 17 on the contiguous block 8, and the other end is fixed in the locating hole 18 of knife section 6 afterbodys.

During use, hold Top carry handle 11 revolute pair handgrips 13, rotate around bearing pin 9 through pull bar 1 pulling knife section 6; At this moment, movable clip block 7 rotates with knife section 6 simultaneously, when clipping to branch; Movable clip block 7 and fixing fixture block 4 are with the branch clamping; Movable clip block 7 no longer rotates, and knife section 6 is rotated further under the pulling of pull bar 1, until branch is cut off.

This averruncator separates the clamping branch cleverly with the action of cutting off branch; Make this averruncator can shear thicker branch; Can guarantee also simultaneously that in the operation of shearing the eminence branch branch of being cut off can arbitrarily not fall down and damage delicate branch and flowers and fruits.
