Abstract

The utility model relates to gardening tool, in particular to the sheer of pruning branches of trees. The technical proposal is to solve the reliability of present garden sheers and not convenient when pruning high branches. The garden sheer consists of two across ream sheer body 1 and 2 which respectively has blade of arc knife-edge and grasp knob, and has concave knife-edge 10 wherein arc knife edge of at least one sheer body. The two-arc knife-edge 8 and 9 present convex and concave shape respectively. The end of blade 4 has introvert-bending hook 11. The utility model is provided a V spring 12 between grip 5 and grip 6, and the two sides of the spring are inserted respectively into convexity jack 14 of the top of the grip, which matches the end of spring.

Description

Orchard shears

The utility model relates to garden tool set, particularly the scissors of plants shoots such as pruning trees.

Existing orchard shears as shown in Figure 2, cut body intersection hinge by two and constitute, each hinge front portion of cutting body is blade, and the rear portion is a handle, two blades of cutting body respectively match and are the homotropous edge of a knife, and promptly the edge of a knife of two blades is respectively the arcs of recesses edge of a knife and the convex edge of a knife.Between two handles of cutting body, spiral spring is arranged, utilize the tension force of spring to open two handles automatically and open two blades.This orchard shears is because two edges of a knife that match are all curved, and when shearing plants shoots, branch is easy to slippage from clip; Secondly, because the two ends of spring and the short column of handle inboard plug, spring is easy to slippage from short column during use, and the function that blade is opened in forfeiture automatically: moreover, because branch is easy to skid off from the edge of a knife, extremely inconvenient for the pruning of the branch of higher position, even can not prune.

Given this, the purpose of this utility model is to provide a kind of orchard shears that can shear branch reliably, and further provides a kind of energy hook to draw the orchard shears of branch, further provides a kind of cutter to open reliable orchard shears again.

The utility model adopts and spill edge of a knife card jail branch to be set in curved edge and can not to skid off so that shear branch reliably and realize its purpose; And further adopt and in the termination of the blade of curved edge crotch is set and draws convenient pruning of branch to realize its purpose with hook; Further adopt again the two ends of spring are inserted respectively in two handle Φ shape jacks so that its connection reliably realizes its purpose.

Orchard shears of the present utility model (referring to accompanying drawing), comprise blade that curved edge is arranged respectively and handle two intersect be hinged cut body (1,2), at least one cuts the curved edge (8) of body, the spill edge of a knife (10) is arranged.

An above-mentioned curved edge (9) of cutting body is concave shaped, and another curved edge (8) of cutting body is spirogyrate.The above-mentioned spill edge of a knife (10) can be in the curved edge of spirogyrate.The spill edge of a knife also can be in the curved edge of concave shaped.Can also in two edges of a knife of cutting body, the spill edge of a knife be arranged all.

Can there be the crotch (11) that bends inwards blade (4) termination of the above-mentioned curved edge that concave shaped is arranged (9).

Between above-mentioned two handles (5,6) of cutting body V-shaped spring (12) can be arranged, insert respectively in the Φ shape jack (14) that the top of two handles matches with spring tip at the two ends of spring.

The utility model is identical with the using method of common orchard shears, has increased the function of drawing branch with the crotch hook in addition.

The utility model has following advantage and effect compared with prior art.

One, spill edge of a knife structure of the present utility model makes the plants shoots that is sheared enter the spill edge of a knife, and can slippage from the edge of a knife, and it is reliable to prune branch.

Two, crotch structure of the present utility model can be used crotch, higher position or branch hook at a distance can be moved to by the side of, so that make things convenient for the pruning of branch.

Three, the Φ shape jack structure of spring of the present utility model, because that the shape of the jack on the shape of the grafting termination of spring and the handle that matches with it is the middle part size is bigger, so spring and to cut the grafting of body reliable, be difficult for deviating from.

The utility model is applicable to the branch of plants such as pruning trees.

Below, the utility model is further described to use embodiment and accompanying drawing thereof again.

Brief description of drawings.

Fig. 1 is the structural representation of a kind of orchard shears of the present utility model.

Fig. 2 is the structural representation of existing orchard shears.

The A-A profile of Fig. 3 Fig. 1.

Embodiment 1

A kind of orchard shears of the present utility model, as shown in Figure 1.Constitute by cutting body 1 and cutting body 2.

Above-mentioned cuts body 1 and cuts body 2, makes the structure that is distortion Z word of common orchard shears, cuts body 1 and is respectively blade 3 and blade 4 with the front portion of cutting body 2, and the rear portion is respectively handle 5 and handle 6.To cut body 1 and cut body 2 and intersect stackedly, be hinged together, and make two blades can opening and closing with the folding of two handles with the middle part of screw 7 with the two bending.

Above-mentioned two blades all are shaped on before cutting body hinge portion and are homotropous curved edge, blade 3 can be made cambered outwards spirogyrate curved edge 8, blade 4 are made the curved edge 9 of the concave shaped that concaves.Make the spill edge of a knife 10 that concaves again at the middle part of curved edge 8.Also can make the spill edge of a knife in addition at the middle part of curved edge 9.Also two curved edges all can be made the spill edge of a knife.

Termination at the blade 4 of the above-mentioned curved edge 9 that concave shaped arranged is shaped on the crotch 11 that bends inwards.

Cut the spring 12 that common V-arrangement is installed between the handle 5 of body and the handle 6 above-mentioned two, the middle part of spring is short spirality.The radial dimension at 13 middle parts, termination at the two ends of spring is greater than the large-diameter portion of the diameter of spring lever portion.The kink at screw 7 rears that promptly are hinged on the top of two handles is made the Φ shape jack 14 that can match with joint 13.The structure of Φ shape jack is shown in 3, promptly in the stage portion at handle hinged part rear along the handle bar to cutting out groove mouth 15, the width of groove mouth is slightly larger than the diameter of spring lever, vertical direction at groove mouth middle part along spring 12 bar portions gets out blind hole 16, the slightly larger in diameter of blind hole is in the large-diameter portion of spring tip, thus on the A-A section jack of shape such as Φ shape.Along the oral area of groove mouth 15, Φ shape jack 14 is put in the termination 13 of spring during grafting.Under the elastic force effect, the termination of spring can not deviate from from Φ shape jack.
