Description

Multifunctional grafting cutter

Technical Field

The utility model belongs to the technical field of grafting instrument, concretely relates to multi-functional grafting cutter.

Background

Grafting is a common crop treatment technology, and branches, stems and leaves of plants need to be cut, trimmed and the like in the grafting process. In the prior art, the cutting and the trimming of branches are carried out independently through a cutting tool and a trimming tool which are relatively independent, the tools need to be frequently replaced when the working procedures are switched, the operation is very inconvenient, and the efficiency of grafting work is also reduced. In the prior art, a cutting tool and a trimming tool are integrated into a multifunctional grafting tool, but the existing multifunctional grafting tool is only used for simply integrating the cutting tool and the trimming tool. The pruning part in traditional multi-functional grafting cutter all includes that two mutual pivoted cutters constitute scissors structure usually, and two pivoted cutters all extend certain length, use because the sheltering from of cutter length itself with interfere for the branch is difficult to in the quick convenient cut-out that imbeds the pruning cutter. Meanwhile, the length of the pruning cutter can cause certain interference to the cutting cutter, so that the use convenience of the whole multifunctional cutter is still insufficient. And the cutting knife and the trimming knife of the traditional multifunctional grafting knife are distributed on two sides, but are exposed outside, so that an operator is easy to be injured.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multi-functional grafting cutter, the function of compatible branch cutting and branch pruning makes the shearing cutter hide when not pruning, can not influence the use of cutting tool.

Detailed Description

Example 1:

the multifunctional grafting tool in the embodiment comprises a first tool handle 1 and a second tool handle 2 which are mutually rotationally hinged, an elastic part 3 is arranged between the first tool handle 1 and the second tool handle 2, and an opening cavity for rotationally mounting the second tool handle 2 is formed in one end of the first tool handle 1; a cutting edge 01 is arranged on one side, close to the second knife handle 2, of the other end of the first knife handle 1, and a shearing groove 02 is arranged at an opening, corresponding to the opening cavity, on one side, far away from the second knife handle 2, of the other end of the first knife handle 1; one end of the second handle 2 extends to the inside of the opening cavity and is provided with a shearing blade 03 corresponding to the shearing groove 02, the shearing blade 03 extends out of the opening cavity along with the rotation of the second handle 2 relatively close to the first handle 1, and the shearing blade 03 is hidden inside the opening cavity along with the rotation of the second handle 2 relatively far away from the first handle 1.

The cutting edge 01 on the first tool handle 1 is used for directly cutting the branches, when the branches need to be cut, the branches are embedded into the cutting grooves 02 to be positioned, and then the second tool handle 2 is pressed, so that the second tool handle 2 rotates towards the direction close to the first tool handle 1. And then the cutting edge 03 on the second tool handle 2 is driven to extend out of the opening cavity on the first tool handle 1 and rotate along with the second tool handle 2 towards the direction close to the cutting groove 02. At the moment, the cutting groove 02 and the cutting edge 03 are closed, so that the branches in the cutting groove 02 are cut off. After the branch is sheared, the second tool handle 2 is loosened, the second tool handle 2 is rotated towards the direction far away from the first tool handle 1 under the elastic action of the elastic piece 3, and then the shearing cutting edge 03 on the second tool handle 2 is driven to be far away from the shearing groove 02 to rotate until the shearing cutting edge 03 returns to the opening cavity again to be hidden. Because the shearing cutting edge 03 is hidden in the opening cavity, the shearing groove 02 can be completely exposed, and then the branches can be more conveniently embedded into the shearing groove 02 for positioning. The shearing blade 03 that hides simultaneously can not influence the use of cutting blade 01 yet, can not occupy the space of cutting blade 01 for cutting blade 01 can do wideer longer, and then promote the convenient degree of branch cutting. Simultaneously, shearing blade 03 is hidden in the inside of opening cavity, can effectively avoid shearing blade 03 when it carries out the cutting operation by the foreign object damage.

Further, the elastic member 3 is a torsion spring.

Example 2:

the embodiment is further optimized on the basis of embodiment 1, as shown in fig. 3, the shearing groove 02 includes a positioning arc surface 021 and a shearing arc surface 022 having the same rotating direction, one end of the positioning arc surface 021 close to the second handle 2 is connected and sealed with one end of the shearing arc surface 022 close to the second handle 2, and one end of the positioning arc surface 021 far away from the second handle 2 and one end of the shearing arc surface 022 far away from the second handle 2 are separated from each other and opened.

The branches are embedded into the shearing grooves 02 and supported and positioned through the positioning cambered surfaces 021, so that the branches are prevented from falling out of the shearing grooves 02. The edge of shearing cambered surface 022 is provided with the blade, and the edge of shearing blade 03 also parallel arrangement has the blade, promotes the shearing force when shearing blade 03 and shearing between cambered surface 022 are closed.

Further, the width of the separation opening between the end of the position cambered surface 021 far away from the second knife handle 2 and the end of the shearing cambered surface 022 far away from the second knife handle 2 is 1cm-3 cm.

Further, the crooked radian of shearing blade 03 is the same with the crooked radian of the shearing cambered surface 022 of shearing recess 02, when shearing blade 03 and shearing cambered surface 022 are closed, makes shearing blade 03 and shearing cambered surface 022 can closely laminate.

Other parts of this embodiment are the same as embodiment 1, and thus are not described again.

Example 3:

the embodiment is further optimized on the basis of the above embodiment 1 or 2, as shown in fig. 3 and fig. 4, a limiting blocking piece 04 is disposed on one side of the first tool holder 1 corresponding to the shearing arc face 022, the side being far away from the positioning arc face 021, and the limiting blocking piece 04 is disposed corresponding to the shearing edge 03. When shearing blade 03 and shearing cambered surface 022 are closed, contact through spacing separation blade 04 and shearing blade 03 and then carry on spacingly to shearing blade 03 extreme rotational position, avoid shearing blade 03 to rotate the dislocation and cause the damage.

Further, the bending radian of the limiting blocking piece 04 is equal to that of the shearing cutting edge 03, so that the shearing cutting edge 03 can be tightly attached to the limiting blocking piece 04 when rotating to the limit position.

The rest of this embodiment is the same as embodiment 1 or 2, and therefore, the description thereof is omitted.
