Abstract

The invention relates to a pair of gun-shaped fruit thinning scissors. The pair of gun-shaped fruit thinning scissors comprises an upper knife rod and a lower knife rod, wherein the upper knife rod and the lower knife rod are arranged on the upper portion and the lower portion respectively, the upper knife rod and the lower knife rod are respectively provided with a front stretching-out arm and a rear stretching-out arm, the front stretching-out arm of the upper knife rod and the front stretching-out arm of the lower knife rod are outwards turnover, and are of a circular-arc-shaped structure in the vertical projection direction, the rear stretching-out arm of the upper knife rod stretches out in an upswept mode, the rear stretching-out arm of the lower knife rod stretches out in a downwards-inclined mode, and the middle position of the upper knife rod is connected with the middle position of the lower knife rod in a rotary mode through a fixing button. The pair of gun-shaped fruit thinning scissors is simple in structure and reasonable in design. Due to the fact that the structural design similar to the shape of a gun is adopted, the pair of gun-shaped fruit thinning scissors accords with the ergonomic principle, and facilitates holding of human hands for operation. Due to the fact that the whole structure of the pair of gun-shaped fruit thinning scissors is small and compact, pruning operation in narrow and small space inside a fruit cluster is facilitated. Fruits needing to be cut off can be conveniently recognized by eyes of a person because of the bent upper knife rod and the bent lower knife rod, and the situation that wrong fruits are cut off cannot happen.

Description

Rifle shape fruit thinning is cut

Technical field

The present invention relates to a kind of rifle shape fruit thinning cuts.

Background technology

In the technique known field, it is big often to run into the fruit tree load capacity in the fruit production, need flower and fruit thinning stage by stage, can grow up smoothly to guarantee fruit, because the fruit tree kind is many, fruit size and fruit ear differences in shape are bigger, fruit tree are pruned the adjacent fruit surface of damaging easily by the fruit thinning scissors in producing at present when removing fruit, cause the fruit surface scar, thereby cause fruit marketability to reduce, during fruit in removing fruit ear, only depend on arm or wrist to adjust the scissors direction, comparatively require great effort, human body has increased the weight of the work burden than fatiguability, has reduced efficiency.

Summary of the invention

The technical problem to be solved in the present invention is: overcome the problems referred to above, provide a kind of not easy damaged fruit surface, laborsaving, the burden that lightens one's labor and the rifle shape fruit thinning of raising labour efficiency to cut.

The technical solution adopted for the present invention to solve the technical problems is: a kind of rifle shape fruit thinning is cut, on having, the following last knife bar that arranges respectively and following knife bar, the described knife bar of going up all has preceding cantilever arm and back cantilever arm with following knife bar, the preceding cantilever arm of described upward knife bar and the preceding cantilever arm of following knife bar outwards overturn, and be arc-shaped structure in the upright projection direction, the preceding cantilever arm of the preceding cantilever arm of knife bar and following knife bar is respectively equipped with edge on described, the described back cantilever arm of going up knife bar stretches out obliquely and is bent upwards in the middle, stretch out under the back cantilever arm of described down knife bar is oblique and be bent downwardly in the middle, the described medium position of going up knife bar is rotationally connected by the medium position of fixing button with following knife bar, be symmetrically arranged with two connecting rods between the end of the back cantilever arm of the terminal and following knife bar of the back cantilever arm of knife bar on described, one end of two connecting rods is terminal hinged with the back cantilever arm of the end of the back cantilever arm of last knife bar and following knife bar respectively, does on the tensile axis of straight reciprocating motion but the other end of two connecting rods all is hingedly mounted on along continuous straight runs.

Further, consider operation for convenience, fixing button of the present invention and tensile axis all are arranged in the housing, are provided with at described tensile axis to stretch out in hull outside and pull button with tensile axis is connected as a single entity.

Further, consider resetting of mechanism, the present invention is arranged with spring at described tensile axis.

Further, consider that the gripping of staff is convenient, housing of the present invention has holds handle.

Further, consider that effect is not pruned in easy damaged fruit, raising, the middle part that the present invention is arranged on the edge on the preceding cantilever arm of knife bar has to cutting edge of a knife or a sword mouth structure lower process, that be the semicircle arcuation, the middle part that is arranged on down the edge on the preceding cantilever arm of knife bar has to cutting edge of a knife or a sword mouth structure upper process, that be the semicircle arcuation, and the direction that described edge stretches out is parallel with the central axis of tensile axis.

The invention has the beneficial effects as follows: the present invention is simple in structure, reasonable in design, employing is similar to the structural design of handgun shape, meet principle of human engineering, the hand of being convenient to the people grips to operate, overall structure is short and pithy, be conducive in the inner small space of fruit ear, carry out cut operation, scissors is curved simultaneously, point of a knife arc Passivation Treatment, and the edge of a knife is hidden in the arc mouth, can not run into fruit during use, reduce damage fruit probability greatly, crooked last knife bar and following knife bar also are convenient to human eye and are identified the fruit that need wipe out, can wrong fruit thinning in fact.
