Description

Pruning shear

Technical Field

The utility model belongs to the technical field of hand tool technique and specifically relates to a secateurs.

Background

At present, in the process of garden or agricultural work, branch shears become main tools for pruning branches, seedlings and the like. The traditional pruning tool adopts a guillotine principle, one of two shearing sheets is a blade, the other shearing sheet is a bed, and branches are cut through the blade; the existing leaf-cutting tool adopts the principle of scissors, and two cutting blades are both blades. The two shearing tools have single function, and cannot be mutually communicated due to structural limitation, and the conventional pruning tool often slides and misplaces when shearing thicker branches, so that normal pruning operation is influenced. In addition, when the traditional pruning shears shear branches, transition dislocation can occur due to the fact that the branches are thick, the lower portions of the main shears and the auxiliary shears are overlapped in a staggered mode, a user needs to spend large effort to pull back the main shears and the auxiliary shears, pruning efficiency is affected, the situations of clamping hands, squeezing hands and the like easily occur in the process of pulling back the main shears with force, safety is low, and use experience is poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pruner with good limiting effect and large shearing force aiming at the defects of the existing pruners.

In order to realize the purpose of the invention, the utility model adopts the technical scheme that: a pair of pruning shears comprises a shear body and a rod body, wherein the shear body is connected with the rod body together, the shear body comprises a main shear and an auxiliary shear, the upper parts of the main shear and the auxiliary shear are respectively provided with a main shear edge and an auxiliary shear edge, the lower parts of the main shear and the auxiliary shear are respectively provided with a main shear handle and an auxiliary shear handle, and the middle parts of the main shear and the auxiliary shear are hinged through a rotating shaft;

the lower part of the main shear blade is of an outwards convex arc structure, the lower part of the auxiliary shear blade is of an inwards concave arc structure, and the positions and the shapes of the two arc structures are matched;

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to the attached drawings 1-3, the pruning shear disclosed by the utility model is an improvement on the existing basis, a limit structure is added, and the phenomena of sliding dislocation and the like in the shearing process are effectively avoided.

The branch shears comprise a shear body and a rod body, wherein the shear body is connected with the rod body, the rod body is omitted in the embodiment, and various conventional rod bodies can be selected as the rod body. The scissors body includes main scissors 1 and vice scissors 4, and the upper portion near side of main scissors 1 and vice scissors 4 is main cutting edge 2 and vice cutting edge 3 respectively, and the lower part of main scissors 1 and vice scissors 4 is main scissors 6 and vice scissors 8, and the middle part of main scissors 1 and vice scissors 4 is through changeing 5 axle articulations. The lower ends of the main scissor handle 6 and the auxiliary scissor handle 8 are fixedly connected with respective rod bodies.

In this embodiment, the lower part (root) of the main shear blade 2 is an outwardly convex arc structure, i.e. an arc convex part, which is a blade part; the lower part (root) of the auxiliary shearing edge 3 is an inward-concave arc structure, namely an arc groove part which is a bed part. The positions and the shapes of the arc convex part and the arc groove part are matched. The trough portion is larger than the maximum shear section. In the shearing process, the shearing of the thin branches or leaves is completed by the upper middle parts of the main shear blade and the auxiliary shear blade, the thick branches lie in the arc groove body part, the shearing is completed through the interaction of the blade part and the bed part, the arc groove body part plays a limiting role in limiting the branches, and the branches are effectively prevented from sliding in the shearing process.

As another preferred embodiment, the inner side of the main scissor handle 6 is provided with a limiting piece 7, and the free end of the limiting piece 7 is tilted towards the side surface of the main scissor handle 6 and is opposite to the inner side of the auxiliary scissor handle 8. In the shearing process, the main shearing handle and the auxiliary shearing handle are close to each other, when the limiting position is reached, the side surface of the free end of the limiting piece props against the inner side surface of the auxiliary shearing handle 8, the limiting effect is achieved on the activity of the shearing handles, the transition dislocation condition caused by overlarge force is effectively compared with the transition dislocation condition caused by overlarge force, and the safety is high.

The lower end of the secondary cutting edge 4 (i.e. the outermost end of the entire cutting edge) is of a bevel structure. The inclined plane structure of vice cutting edge lower extreme inclines to main cutting edge side, can see out by figure 1, and the lower extreme tilt up of vice cutting edge promptly to main cutting edge side perk, and at the shearing in-process, the tip inclined plane of vice cutting edge plays the guide effect, guarantees the front and back position relation of main cutting edge and vice cutting edge, prevents to take place the direct of the blade body to colliding with, effectively avoids the damage of colliding with of the blade body.

As the preferred technical scheme, the main shear blade and the auxiliary shear blade are both wide cutting edges.
