Abstract

The utility model relates to garden tools technology field and discloses a flat bough shear. The utility model comprises two blades hinged with each other and two handles, wherein the back end of the blade are connected with the head of the handles by wire wrapping respectively, a meshed gear is mounted on the head of the handles, the center of the gear is hinged with the two ends of the connecting rod. The centers of the two gears and the wire wrapping point form an equilateral triangle. A shock absorbing pad is mounted on the inner side of the head of the handle respectively. The utility model use gears transmission principle and reduces the labor intensity; therefore, the handles are not hard too hare to be fold and opened to drive the blades. In addition, the utility model makes the blades and the handles to move synchronously, for the equilateral triangle the centers of the two gears and the wire wrapping point, thereby reaching the effect of saving more labor.

Description

Flat mouthful of tree bar cut

Technical field:

The utility model relates to the garden tool set technical field, especially relates to a kind ofly being used to shear flat mouthful of tree bar modifying branch and cutting.

Background technology:

Current, along with expanding economy and growth in the living standard, people also progressively improve for the requirement of household and working environment, and in order to beautify surrounding enviroment, people plant some and view and admire tree near be everlasting dwelling house and office space.Ornamental trees and shrubs need often to prune the tree bar, usually the employed flat mouthful of tree bar of people cut just simply by two with hinged the forming of the integrated blade of handgrip, effort comparatively in the process of pruning trees, tired easily.In addition, these flat mouthful of traditional tree bars are cut no incabloc function, also cause user's the tingle phenomenon of hand in the process of pruning trees easily.

The utility model content:

The purpose of this utility model is the weak point that exists at prior art and provides the flat mouthful of tree bar in a kind of more labour-saving to cut.

For achieving the above object, the utility model comprises two hinged blades and two handles, and wherein, the rear end of blade is hinged with the head of handle respectively, the head of handle forms the gear that is meshed respectively, and the center of gear is then hinged with the two ends of connecting rod respectively.

The central point of described gear and the pin joint of blade constitute equilateral triangle.

The inner portion of described handle is the moulding antivibration pad respectively.

The beneficial effects of the utility model are: its handle has utilized gear drive labour-saving principle, and it is too painstaking can not feel when user's opening and closing handle drives blade movement, has alleviated operation intensity.In addition, the central point of two handle head gears and the pin joint of two blades constitute equilateral triangle, blade and handle are synchronized with the movement, thereby further reach the labour-saving effect.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the partial enlarged drawing at A place in the accompanying drawing 1

Embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1: flat mouthful of tree bar of the present utility model cut and comprised 10,20 and two

handles

30,40 of two hinged beak-like blades, the rear end of

blade

10,20 is hinged with the head of

handle

30,40 respectively, the head of

handle

30,40 forms the

gear

31,41 that is meshed respectively, and the center of

gear

31,41 is then hinged with the two ends of connecting rod 50 respectively.Because gear transmission mode is comparatively laborsaving, can alleviate the operation intensity of user when pruning the tree bar.

See shown in the dotted line in the accompanying drawing 2: the pin joint of the central point of

gear

31,41 and

blade

10,20 constitutes equilateral triangle, can guarantee the synchronism between the

blade

10,20 and handle 30,40 in the operation process like this, further reaches the labour-saving effect.

In addition; the inner portion of

handle

30,40 is moulding

antivibration pad

32,42 respectively, like this, even handle 30,40 fiercely collides in the process of using the tree bar;

antivibration pad

32,42 also can be dissolved the seismaesthesia that is delivered to user's palm of the hand, thereby reaches the purpose of protection user hand.
