Abstract

Large-cutting-force scissors belong to the technical field of gardening tools. The technical scheme of the scissors includes that a fixed base is mounted at the top end of a hollow steel pipe, a fixed cutting edge is mounted on the fixed base, and one end of a movable cutting edge is hinged to one end of the fixed cutting edge. An elbow rod boosting mechanism consisting of two connecting rods, two press handles, a handle base and a pull strip is arranged at the bottom end of the hollow steel pipe, and two ends of the pull rod are hinged to the movable cutting edge and the upper end of the pull strip respectively. The large-cutting-force scissors for gardening can generate large cutting force, and can pull tree branches, so that tree branches which are cut are easy to separate.

Description

Scissors is used in a kind of big shearing force gardens

Technical field

The utility model relates to a kind of gardens scissors, refers in particular to a kind of big shearing force gardens and uses scissors, belongs to the garden instrument technical field.

Background technology

At present, in the product of pruning high-altitude flowers and trees, the employed gardens of branch scissors, although structure is not quite similar,, all exist such defective: the one, the shearing force that is produced is less than normal; The 2nd, branch inconvenient and to flowers and trees, branch carries out drawing-type to be separated.

Summary of the invention

The purpose of the utility model is: carry out the defective that drawing-type separates to the existing existing shearing force that produces of gardens scissors branch less than normal, inconvenient and to flowers and trees, branch; The utility model provides a kind of big shearing force gardens to use scissors; This kind scissors can produce bigger shearing force; And can carry out tractive to tree branches, make the branch easy separation that is sheared.

The utility model realizes that the technical scheme that above-mentioned purpose adopted is: scissors is used in a kind of big shearing force gardens; It comprises: pressure handle, connecting rod, seat, hollow steel pipe, tie rod, holder, the fixedly edge of a knife, the movable edge of a knife, pull bar, bearing pin; It is characterized in that: the top at hollow steel pipe is equipped with holder, and the fixedly edge of a knife is installed on holder, an end of the movable edge of a knife and fixedly an end of the edge of a knife be hinged together with bearing pin; The fixing similar relation with scissors of the edge of a knife and movable blade interruption-forming; On the cylindrical of the bottom of hollow steel pipe, install and fix the handlebar seat symmetrically, pressure handle, connecting rod are made up of two identical institutes, and the end of each pressure handle and one are hinged seat together; The upper end of each root connecting rod and a pressure handle are hinged together; And symmetrically, in the interstitial hole of hollow steel pipe, be provided with tie rod between two connecting rods, the lower end of the lower end of tie rod and two connecting rods is hinged together; Two connecting rods and two pressure handles and constituting the toggle link force-increasing mechanism between seat, the tie rod, the two ends of pull bar become hinged relationship to link together with the upper end of the movable edge of a knife and tie rod respectively.

Beneficial effect: the utility model is because after adopting said method, by having the function of reinforcement with elbow-bar mechanism, so; Can counter brace produce bigger pulling force, the driving activity edge of a knife is done shearing motion, thereby makes the fixedly bigger shearing force of generation between the edge of a knife and the movable edge of a knife; Simultaneously; Owing to fixedly install in vertical direction basically between the edge of a knife and the movable edge of a knife and the handle, help being sheared the tractive of branch, impel it to help separating.
