Description

Orchard shears lever buckle structure

Technical field

The utility model relates to a kind of orchard shears, refers to a kind of topiary branch usefulness that is used for especially, and can when non-working condition blade be folded hidden orchard shears lever buckle structure.

Background technology

General flowers and plants have toughness mostly, branch often is again thick and stiff kenel, therefore the orchard shears that is used for the topiary branch, its blade must have enough intensity and sharpness, and for fear of in hand-held walking or when non-working condition such as placing, is hurt by sharp knife edges, therefore must be with two lever pressings, it is hidden that sharp blade is folded, and make two lever snap fit by a structural member, to reach the effect of security protection.

As Fig. 1, shown in Figure 2, it is a kind of existing orchard shears lever buckle structure, it comprises: one first lever 10, one second lever 20, one blade sheet 30, one linking arm 40 and a fastener 50, wherein first lever, 10 ends are provided with a cutter anvil 11 and a fluting that runs through 12, second lever 20 and first lever 10 articulate, medial surface is provided with a groove 21, blade sheet 30 is located in the fluting 12 interior pivots of first lever, 10 ends and consolidates, and form corresponding shape with cutter anvil 11, its end is provided with a multistage location notch hole 31 and a buckle projection 32, the groove 21 interior pivots that linking arm 40 1 ends cooperate an elastic parts (not shown) to be plugged on second lever 20 are consolidated, the multistage location notch hole 31 that the other end wears an axostylus axostyle and blade sheet 30 articulates, fastener 50 is to extend a skewed articulated section 52 by an en plaque trigger piece 51 inner faces, trigger piece 51 is provided with a buckle slot 53 with 52 front sides, articulated section, and articulated section 52 is plugged in the groove 21 of second lever 20, wear pivot admittedly with a pivot 60.

And when non-working condition, first,

second lever

10,20 is pushed to opposite side, blade sheet 30 and cutter anvil 11 are fitted, again by trigger piece 51 with fastener 50 switching forward, the buckle piece 32 of blade sheet 30 ends is entered in the buckle slot 53 of fastener 50, the butted formation snap fit that cooperates elastic parts is controlled sharp blade and is kept folding hidden state, to avoid causing incised wound.

But, owing to should have orchard shears lever buckle structure now, its fastener 50 is to reach positioning action by the frictional force between 52 two sides, articulated section and second lever, 20 grooves, 21 internal faces, thereby after using a period of time, promptly easily produce loosening because of wearing and tearing, fastener 50 has the defective of arbitrarily rocking the normal usage operation of obstruction when causing shearing to use, and ease of use and practicality are not good.

The utility model content

Designer of the present utility model is because existing orchard shears lever buckle structure, after using a period of time, fastener promptly easily loses positioning action, use operational inconvenience and cause, and the idea of thinking and creating, through inquiring into and study sampling test in many ways, reach and repeatedly revise improvement, and release the utility model.

The purpose of this utility model is to provide a kind of locating effect of strengthening, and difficult the generation become flexible and the normal use of obstruction, and can improve the orchard shears lever buckle structure of ease of use and practicality with user's demand clip at an arbitrary position.

The utility model provides a kind of orchard shears lever buckle structure, it comprises: one first lever, one second lever, one blade sheet, one linking arm and a fastener, wherein the first lever end is provided with a cutter anvil and a fluting, second lever and first lever articulate, the blade sheet is arranged in the fluting pivot of first lever and consolidates, and form corresponding shape with the cutter anvil, its end is provided with a multistage location notch hole and a buckle projection, linking arm one end is plugged on the interior pivot of groove of the second lever medial surface and consolidates, the other end articulates with the multistage location notch hole of an axostylus axostyle and blade sheet, fastener is to extend an articulated section by a trigger piece inner face, and the front side is provided with a buckle slot, and the articulated section is provided with at least one flexure strip, and the articulated section is plugged in the groove of second lever, wear pivot admittedly with a pivot, make the butted groove internal face of flexure strip, reach the reinforcement locating effect.

The beneficial effects of the utility model, be that its fastener is to reach positioning action by the frictional force between two sides, articulated section and the flexure strip and the second lever groove internal face, thereby can strengthen locating effect, be difficult for producing loosening normal use that hinder, and can improve ease of use and practicality with user's demand clip at an arbitrary position.
