Abstract

The utility model provides a picking and pruning lopper. The picking and pruning lopper comprises a fixed blade fixed with a fixed clamping block and an L-shaped moving blade hinged with the fixed blade and a moving clamping block, wherein a fixed pin is arranged at the tail of the moving blade and connected with an operating handle through a pull rod, the pull rod comprises an upper pull rod and a lower pull rod, a hanging pin is arranged on the upper pull rod body, an adjusting nut is disposed at the lower end of the upper pull rod, the upper end of the lower pull rod is connected with the adjusting nut through threads, a compression spring is arranged at the lower end of the lower pull rod, a connecting hole is arranged at the tail of the moving clamping block, and a tension spring is arranged between the connecting hole and the hanging pin. According to the picking and pruning lopper, brunch clamping is separated from branch shearing skillfully, so that branches which are 15mm-20mm thick can be sheared, and simultaneously, delicate branches, and sheared brunches cannot fall off randomly, so that flowers and fruits can be prevented from being damaged during operation of branches at high positions.

Description

A kind of averruncator of really pruning of plucking
Technical field
The utility model relates to a planting fruit-trees, garden instrument, more particularly relates to a kind of averruncator of really pruning of plucking.
Background technology
At present, the operations such as pruning, harvesting in the orchard, the instrument that generally uses is averruncator, general averruncator all is comprised of knife section, fixed blade, a long cylinder bar, pull bar, Top carry handle and assistant's handle, and this averruncator can only be completed the pruning operation of branches of tall trees, and, the disconnected branch that is pruned away is from setting upper whereabouts naturally, blocked by crotch sometimes, in the process that drops, disconnected branch can damage delicate branches and leaves or damage flowers and fruits sometimes.Although there is a kind of averruncator to be fixed with fixture block on dynamic and static blade, it is the thick branch of 6mm-7mm that this kind averruncator also can only be cut off diameter, to slightly thick any branch, it is when shearing, with the branch clamping, anti-to the shearing that has hindered dynamic and static blade due to fixing fixture block, so, this averruncator only is only applicable to cutting, repairing of general thin branch, is not suitable for fruit picking.A kind of averruncator was once disclosed in the patent No. is 201220149157.7 patent, although the fixture block on this averruncator knife section is not and the fixing all-in-one-piece of the cutter hub of knife section itself, but, its fixture block is to be hinged on fixed blade and the hinged bearing pin of knife section by a contiguous block around knife section, this kind structure not only chucking power is little, and complex structure, the volume of cutter head is large, is unfavorable for the shearing work of branch.Simultaneously, the edge bevel gradient of knife section is larger, and the shearing force that need use when shearing is larger.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model provide a kind of simple in structure, shear laborsaving and low cost of manufacture pluck the fruit averruncator of pruning.
the utility model is achieved through the following technical solutions: a kind of averruncator of really pruning of plucking, comprise and be fixed with the fixedly fixed blade of fixture block, " L " shape knife section hinged with fixed blade, movable clip block and long cylinder bar, pull bar and manipulating handgrip, the afterbody of described knife section is provided with steady pin, described pull bar comprises upper connecting rod and lower link, the upper connecting rod upper end is fixed on steady pin, be provided with on the shaft of upper connecting rod and hang pin, the lower end of upper connecting rod is provided with adjusting nut, the upper end of lower link is connected with adjusting nut by screw thread, the lower end of lower link is connected on manipulating handgrip, manipulating handgrip is fixed on the lower end of described long cylinder bar by end cap, the upper end of lower link also is provided with setscrew nut, is provided with Compress Spring between setscrew nut and end cap, the afterbody of movable clip block is provided with the breach with the steady pin coupling, also is provided with connecting hole, between connecting hole and described extension pin, extension spring is set, the tail end of described fixed blade is fixed on the upper end of described long cylinder bar.
In such scheme, for reducing shearing resistance, the edge bevel of described knife section extends to the knife back from cutting edge always.
In such scheme, for keeping high chucking power, the surface of described fixture block is provided with the fin of falling the sawtooth.
The utility model is plucked fruit and is pruned averruncator compared with prior art, and its beneficial effect is:
1, owing to being provided with extension spring between movable clip block and pull bar, so just make between movable clip block and knife section a buffering is arranged when knife section and fixed blade suit, in cutting off the process of branch, at first carry out holding action, can guarantee that branch is held not slippage, can effectively branch be cut off again.
2, it is ingenious that this plucks the high branch shears structure of really pruning, easy to use, not only be fit to the shearing of thin branch, also be fit to shear thicker branch, also can guarantee simultaneously in the operation of shearing the eminence branch, can arbitrarily not fallen down by the branch cut off and subsidiary fruit and damage delicate branch and flowers and fruits, be fit to very much component heavier and be afraid of to draw, be afraid of the harvesting of the fruit that falls.
3, this to pluck the fruit high branch shears structure of pruning simple, low cost of manufacture resets flexibly, shearing force is large.
