Abstract

The utility model discloses vertical scissors in the high ground for fruits, farming, and forest, which are composed of upper scissors (1), lower scissors (2), a sliding bar (3), a sliding sleeve (4), a pull rod (5), a spring (6), fixed pulleys and movable pulleys (7) (8) (9), a main rod (10), a push handle (11), and a lower grasping-handle (12). The vertical scissors in the high ground for fruits, farming, and forest are pushed and pulled by the grasping-handle; the fixed pulleys and the movable pulleys are driven; the vertical scissors in the high ground for fruits, farming, and forest are made to generate shearing force with a plurality of multiples; the fixed pulleys and the movable pulleys in the rod and the grasping-handle adopt the design of the push-and-pull, etc., and the high ground operation is without a ladder. The utility model has the advantages of labor saving, high efficiency, large shearing force, and portable carrying, and the vertical scissors in the high ground for fruits, farming, and forest are an ideal hand-held tool for the workers of the fruits, the farming, and the forest.

Description

Vertical scissors in high above ground for fruit, farming, forest

A kind of fruit, farming, the forest high-altitude is vertical cuts.They belong to gardening beta pruning instrument.

Current, really, farming, the forest beta pruning adopts " hand secateurs " more, when staff reaches, then need use the ladder ascend operation, whenever changes one tree and must move ladder one time, this brings heavy manual labor and inconvenience to the garden workers.

The purpose of this utility model provides a kind of fruit, farming, the forest high-altitude is vertical cuts, and the garden workers use the present invention to stand in just can prune high-altitude fruit, farming, forest on the ground freely, and workers are emancipated from hard work the garden.

The utility model is achieved in that

Really, farming, the forest high-altitude is vertical cuts, it by last scissors (1), lower scissors (2), slide bar (3), sliding sleeve (4), pull bar (5), spring (6), fixed, movable pulley (7) (8) (9), total bar (10), push away handle (11), lever (12) is formed down.Last scissors (1) is fixed on the upper end of slide bar (3), the slide bar inwall is provided with parallel keyway, purpose is that last lower scissors is controlled at parallel scope, lower scissors (2) is fixed on sliding sleeve (4) upper end, the inwall of sliding sleeve is provided with parallel keyway (20), be parallel motion with the parallel key (21) of slide bar (3), pull bar (5) upper end fixes splice grafting with slide bar (3), a pulley (7) is adorned in the lower end, spring (6) is contained between pull bar (5) and the sliding sleeve (4), to terminate at the slide bar lower end on the sliding sleeve then, will terminate at the upper end of total bar (10) under the sliding sleeve.Total bar (10) upper end fixes splice grafting with sliding sleeve (4), and the lower end fixes splice grafting with following lever (12), and total bar bottom is provided with parallel keyway (20), and purpose is to make to push away the handle parallel motion.Push away handle (11) and be parallel motion with total bar, inner diameter wall has parallel key (21), and lower end side leaves the hole and connects chain wheel rope.The upper end of following lever (12) fixes splice grafting with total bar (10), internal diameter is equipped with a fixed block (8), and chain wheel rope requires toughness, stretching resistance big, and its end connects and pushes away handle (being the A point), the other end is fixed in lever interior (being the C point) down, and other end interconnects through a movable pulley (9).

Design principles such as this high altitude scissors utilization bar movable pulley decided at the higher level but not officially announced and lever push-and-pull, make it to operate comfortable laborsaving, and efficient height, shearing is big, general 20～30mm branch can be finished a piece of writing at one go.This cuts and particularly adapts to 3～5 meters even higher operation.Its another advantage is the neat extension that do not have, and all structures place in the bar.

High altitude scissors groundwork principle is: the lever push-and-pull, drive is decided movable pulley and is made scissors produce shearing.When 1. lever (12) pushes away handle (11), drive chain wheel rope and at first decide movable pulley (9), make it to be transformed into downward pulling force, pass through upper end two movable pulleys (7) (8) again through interior one of bottom bar, pull bar (5) is cut in pulling, and makes scissors produce the shearing of several multiples.2. after cutting thing and cutting off, when pushing away handle (11) when stopping power, clip will be flicked by bar inner spring (6), pushes away handle (11) and also just restores thereupon.

Characteristics of the present utility model:

1. the high altitude scissors simple structure is easy to use, and is comfortable laborsaving.

2. shearing is big, the efficient height, and general 20～30mm branch can be finished a piece of writing at one go.

3. use the present invention to carry conveniently, no longer need ladder.Be fruit, farming, handheld tool that the forest worker is desirable.
