Description

Foot-operated fruit tree scissors

Technical field

The utility model relates to a kind of pruner, is espespecially applied in pruning trees branch on gardening, connects the foot-operated fruit tree scissors of scissors and foot pedal apparatus by drag-line.

Background technology

Known pruner has common hand held pruner, electric pruner, pneumatic pruning shears cutter, shears for pruning upper branch etc.

But known pruner has many structures and occupation mode, there are unavoidably some shortcomings to have much room for improvement, the for example garden shears shown in Chinese patent 2012202364812, while pruning branch, need the strength of hand to shear branch, in the time pruning the branch that workload is large or shearing is thicker, because of people's hand-power limited, so shear branch quite arduous.

Moreover, although some pruner, without people's shearing branch of having an effect, needs charging, general work 8 hours, the working time is limited; The weight that scissors is nearly 900 grams, is used arm to ache for a long time, has increased sense of fatigue to people.This class designs as Chinese patent 2011102063726, Chinese patent 2011200335204, Chinese patent 2012301804238 etc.

[0005]although power is done in some not electricity consumption of scissors in addition, need air pump to drive, oil firing, increase use cost; Whole system configuration is complete higher with respect to other pruner prices; When work, involve pipe and use inconvenience; When breaking down, system keeps in repair inconvenience.This class designs as Chinese patent 201220359767X, Chinese patent 2010102560052.

Also have some pruners, although can repair eminence branch, repair lower branch inconvenient, for example Chinese patent 2013202476013, Chinese patent 2012200934826.

In view of this, the technical problems to be solved in the utility model is to provide a kind of pruner: people can effortlessly easily cut off branch, work long hours and can not produce sense of fatigue, longevity of service, the pruner light and handy convenient, the low branch of branches of tall trees can conveniently be pruned.

utility model content

In order to address the above problem, the technical solution of the utility model is achieved in that a kind of pruner, and it comprises: scissors part, and it comprises cutter head, spring, upper lower handle; Drag-line part, it comprises that stainless steel band steel wire rope, steel wire rope top connection, steel wire rope lower link, drag-line flexible pipe, flexible pipe top connection, flexible pipe lower contact, flexible pipe top connection be affiliated to nut; Foot pedal apparatus, it comprises conduit, support, base plate, backing plate, pedal, heel slip panel beating, locking groove, spring, bolt, bearing pin, brace, footmuff; The most of composition of extension bar four.Scissors part connects drag-line part, and drag-line part connects foot pedal apparatus.

As preferred version, cutter head adopts screw to be connected with handle, is convenient to change cutter head.

As preferred version, steel wire rope adopts bag stainless steel band steel wire rope.

As preferred version, foot pedal apparatus and upper lower handle are manufactured with stainless steel.

As preferred version, flexible pipe top connection is affiliated to nut and is adopted slotting extension to be connected with lower handle.

As preferred version, perforate fluting in pedal rear portion uses bearing pin to connect in flakes, connects in flakes guide rod again.

As preferred version, opening slot before pedal middle part design pedal, by the panel beating stop of slip heel so that walking.

As preferred version, between the connecting bolt that pedal and base plate are connected, wear torsion spring and be convenient to scrunch.

The technique effect that the utility model reaches is as follows: more than 300 gram of the utility model portion of the handle, has reached and used lightly effect easily.The utility model utilizes people's gravity and strength that pin is pedaled to drive scissors to prune branch downwards, has reached Labor-saving high-efficiency, and not electricity consumption is oil firing not, the effect of energy-saving and environmental protecting.The utility model is simple in structure, has reached and has maintained effect easily.The utility model can also, by adding extension bar pruning eminence branch, reach the effect of averruncator.
