Abstract

The utility model relates to a pair of small fruit shears, comprising an upper handle 11, a lower handle 5, a cutter 1, etc., wherein, the cutter 1 forms a lever by using a pin shaft 2 as a supporting point. The utility model is characterized in that the force point of the cutter is connected to the lever of the lower handle which uses a pin shaft 10 as a supporting point by a connecting rod 6, and thus, the force arm of the small fruit shears is added, which makes cutting save labor, and the structure compact. The elastic force of springs 7, 9 arranged on the pin shaft 8, 10 drives the cutter to open normally, so that the clamped lower handle reset automatically, and thus work efficiency is enhanced, and the working strength is lightened. With smart appearance, portable use, and wide range of application, the small fruit shears can be used in various places, such as farms, orchards, green houses and families.

Description

Small fruit shears

The utility model belongs to the gardening instrument, the small-sized flower twig clippers that particularly a kind of suitable farm, orchard, greenhouse, family use.

Now Chang Yong flower twig clippers handle is long, body is big, heavy, and when operation need both hands firmly, so very easily make people's fatigue, and cut back and forth all and need use manpower, effect is also low.

The purpose of this utility model be to design one laborsaving, effect is fast, the little slim and graceful small-sized flower twig clippers that only needs one-handed performance of body.

The purpose of this utility model is achieved in that on the lever arm of force of conventional scissors, with a connecting rod it is linked to each other with the lever of setting up at the lower handle place dexterously, so that arm of force lengthening, shear laborsaving, and structure is very compact, thereby realize the energy one-handed performance, body is little, slim and graceful, the purpose of raising effect.

With drawings and Examples structure of the present utility model is further narrated below:

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of cutting knife 1.

As seen from Figure 1, it comprises upper handle 11, lower handle 5, one end of upper handle 11 is half sheet scissor, it is characterized in that, lower handle 11,5 are shell shape, the cutting knife 1 that one end is the semishearing knife-edge links by bearing pin 2 and upper handle 11, lower handle 5 links by bearing pin 10 and upper handle 11, on bearing pin 10, be provided with one and make lower handle 5 normal open springs 9, one end of spring 9 is stuck in the inwall of lower handle 5, one end of connecting rod 6 links by bearing pin 8 and lower handle 5, its other end links by bearing pin 3 and upper cutter 1, installing bearing pin 3 places on cutting knife 1 are provided with an elongated slot 12, be provided with one and make the spring 7 that chain bar 6 and lower handle 5 can opened with certain angle on bearing pin 8, an end of spring 7 is stuck in the inwall of lower handle 5.

Lower handle 5 is one to be the lever of fulcrum with bearing pin 10 in the said structure, and this two lever links to each other by connecting rod 61 of cutting knife dexterously in order to make the lever of fulcrum with bearing pin 2, makes the arm of force lengthening of cutting knife 1 lever, but and its structure is very compact; Spring 9,7 all makes this flower twig clippers keep voluntarily often opening, so operating personnel only need cutting when cutting firmly, cutting knife cut the back by spring from horizontal reset, do not need to use manpower again, thereby saved man-hour and manpower; The effect of the elongated slot 12 on the cutting knife 1 is to make the open-angle of cutting knife 1 to increase, because it can change the position of bearing pin 3, subtended angle is with regard to increase, so it is big to cut the scope of cutting; In addition in order to make this flower twig clippers slim and graceful, be shell structure (inner hollow out) with two handles among the design, guaranteeing that weight is the lightest under the prerequisite of intensity, upper and lower in force handle adopts reinforced nylon to make, so that weight is more slim and graceful.

Cutting knife 1 is the thin cutter of a symmetric figure twolip as seen from Figure 2, and angle is 8～12 ° between twolip, and the thickness of cutting knife is 1.5～2mm, adopts No. 50 carbon structure steel to quench and makes.This slim clip angle twolip cutting knife, stressed even during shearing, shear fast.

This small-sized flower twig clippers also can be provided with a safe snap ring 4 on lower handle 5 in addition, and it can buckle among the breach 1a of blade 1, and at this moment, cutting knife 1 is in complete closure state, in order to avoid cutting knife is accidentally injured the people, decreased thing.

To shear fashion and exert all one's strength in order to make to hold, lower handle 5 is designed to outer spill, and upper handle 11 is designed to spirogyrate.

In sum, this small fruit shears has compact conformation, and body is little, slim and graceful, laborsaving, shearing is fast, the power advantages of higher, so it can be widely used in farm, orchard, greenhouse, family, and has good economic, practical value.
