Description

Labor-saving gardening shear structure

Technical field

The utility model is related to a kind of orchard shears, orchard shears knot that is espespecially a kind of laborsaving and can once reaching shear effect Structure.

Background technology

Press, existing labor-saving gardening shear structure, please refer to shown in Fig. 9 to 12, the orchard shears 50 is mainly by one first The handle 52 of handle 51 and second bolt has a fulcrum, makes to produce between the handle 52 of the first handle 51 and second to support, wherein One end of first handle 51 is provided with a cultellus portion 511, and wears a cutting edge piece 53 in the stage casing position of the first handle 51, so as to inciting somebody to action The cutting edge piece 53 forms a shearing end with cultellus portion 511, and one end of cutting edge piece 53 is between the first handle 51 and the second handle 52 Between there is an adjustment groove 531, should wherein the second handle 52 is pivoted with an outwardly drive rod 54 adjacent to the side of fulcrum Drive rod 54 is inserted in the adjustment groove 531 of cutting edge piece 53 provided with the pivot of a trolley 541, then at the first handle 51 and drive rod 54 Between be provided with spring 55, during the shear history for making the first handle 51 and the second handle 522 be closed and supported, the cutting edge piece 53 is also Elastic gearing can be produced, and the drive rod 54 forms an angle for being less than 90 degree between the second handle 52 and cutting edge piece 53 so that Trolley 541 on drive rod 54 can produce displacement in adjusting groove 531 on cutting edge piece 53, and remain less than the gearing of an angle of 90 degrees Angle.

When the existing structure operates, the trolley 541 of the drive rod 54 is sitting at the first position of adjustment groove 531, in When being that operator firmly presses the first handle 51 and the second handle 52, due to the relative pass of adjustment groove 531 and trolley 541 System so that the half that the opening that the cutting edge piece 53 and the cultellus portion 511 are formed only always is open is less than being equal to and cut into being cut thing At about 1/3rd, and continue to exert a force cutting edge piece 53 and cultellus portion 511 can not also be closed and reach shear effect, so operator First by after the first handle 51 and the semi-coast of the second handle 52 the first handle 51 and the second handle 52 can be pressed again, now The trolley 541 then can escape first position and displacement clip in the second place, so when operator's pressure is sheared again During operation, you can labour-saving will be cut thing and be cut easily.

See above-mentioned existing structure in detail to be not difficult to realize that it has remained a little weak point, main cause is returned as follows：Existing gardening The laborsaving setting cut, though can really reach the effect of expected, for operator, its unique missing is cutting process In must be segmented force shearing, at least want two to four ability will be cut thing cutting, and every time force cut when also by first The semi-coast of 51 and second handle of handle 52, allows the certain escape displacement of trolley 541, then identical action, ability is repeated To be cut thing to cut, its not only operationally must through repeatedly could cut cause use it is upper it is not easy outside, can also influence It straight can not be trimmed to the section for being cut thing, so labour-saving orchard shears still has improved necessity, try to achieve the province of more ease of Use Power designs.

Utility model content

The utility model technical problem to be solved is to be directed to above-mentioned missing existing for prior art, there is provided one kind saves Power structure of gardening scissors.

A kind of labor-saving gardening shear structure provided by the utility model, comprising：

One first lever and one second lever that front end is mutually bolted together, the front end of first lever are provided with a cultellus Piece, and neighbouring cultellus piece wears notch in side provided with one；

One cutting edge piece, comprising a blade part, and a linking part for extending the blade part rear end, the blade part and link An axis hole is provided between portion, and a positional punch is provided with linking part, the cutting edge piece is to hold blade part by first from lower to upper Handle wears notch, and is pivoted with the axis hole and the first lever, the blade part folding is corresponded to the cultellus piece, and the link Portion is then limited between first lever and second lever；

One drive link, the activity of one end are articulated in second lever, and in limiting the drive provided with one in the second lever The butting section of dynamic connecting rod, the other end are then hubbed at the positional punch of the cutting edge piece using a latch, drive link is held with second Maximum expanded angle between handle is through butting section and cutting edge piece limitation and between 120 degree to 140 degree, and neighbouring first lever is with being somebody's turn to do More it is installed with an elastic component at the pivot points of second lever, then clip is articulated in second in drive link and held for the another end of the elastic component The end of handle.

Wherein, the cultellus piece root edge of the first lever forms a pivoting part, and provides the second lever bolt with the pivoting part and connect Knot.

Wherein, one end of drive link is provided with a bolt hole, and is articulated in the second lever with unification axle bolt, and in the end Provided with a clip fin, so that the clip of elastic component another end is fixed.

Wherein, the linking part end of the cutting edge piece has a buckling parts, and coordinates in the second lever and be provided with a fastener, with Buckle is fixed when being closed for the first lever and the second lever.

Wherein, the gardening is cut to the small-sized secateurs that one-handed performance uses.

Wherein, the gardening is cut to the large-scale secateurs that bimanualness uses.

The effect of compareing prior art：The orchard shears reaches the drive link by the butting section of the second lever and supports angle Amplification so that the angle between drive link and the second lever and cutting edge piece makes the first lever and the between 120 degree to 140 degree The force arm formed between two levers is more than the drag arm formed between blade part and cultellus piece, and shearing power can not only be substantially improved Transmit, using above can be more laborsaving, on the other hand allow the pressure that blade part and cultellus piece can be in the first lever and the second lever once Under cooperation is dynamic, reach the shear effect of knife closure, the convenience that real lamps structure uses, and the enhancement of effect.
