Abstract
The utility model relates to a labor-saving branch cutter for cutting branches, comprising two cutter bodies hinged with each other, wherein the two cutter bodies are provided with handles and cutter cutting parts; the cutter cutting part of at least one cutter body is provided with a groove-shaped cutting edge. The labor-saving branch cutter can easily cut branches with big diameter, and the cutting surface is smooth and the bark is undamaged, the interior tissues of branches are not harmed; as a result, the utility model is particularly suitable for the cutting in gardens and the trimming of branches of mulberries.
Description
Technical field
The utility model relates to scissors, especially shears the scissors of branch.
Background technology
After silkworm in spring, autumn, silkworm was raised end, can grow luxuriant mulberry leaf for making mulberry tree when educating silkworm, a lot of branches that often will cut off mulberry tree are done, and the shearing place otch that branch is done is concordant, bark is intact, do not have and tear phenomenon next time.
The scissors that present silkworm raiser shears the branch use mostly is orchard shears branch scissors greatly, it comprises two scissor bodies of intersection hinge mutually, all have handle on the scissor body, the scissor body blade is the crescent shape curved edge, this branch that can shear easily about diameter 10mm, when the branch about shearing diameter 20mm, branch will be along the outside slippage of cutting edge, shear the hinge fulcrum of stress point thereby make away from scissors, the scissors arm of force is prolonged, moment strengthens, the shearing strength that therefore will cost a lot of money just can be cut off thicker branch, even can't implement the shearing to branch at all, also this phenomenon can take place when other occasion is sheared the thicker branch of other type.The branch otch of this scissor cut is coarse simultaneously, also tears bark sometimes.In addition, also damage the interior tissue of branch during this scissor cut easily because of the extruding branch, be unfavorable for the germinating growth of the new twig of mulberry tree, reduce mulberry leaf output.
The utility model content
Technical problem to be solved in the utility model provides a kind of laborsaving branch scissors, and otch was neat when it not only sheared branch, bark is intact, do not damage the branch interior tissue; And it is also very laborsaving to shear thicker branch.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: a kind of laborsaving branch scissors, comprise two scissor bodies that are hinged mutually, be respectively equipped with handle and scissors blade on this two scissor body, have at least the scissors blade of a scissor body to be provided with a Baltimore groove cutting edge.
After adopting said structure, owing to be provided with the Baltimore groove cutting edge at the blade of scissor body, when shearing thicker branch, branch is in the Baltimore groove cutting edge, and outwards slippage and away from the hinge fulcrum has the fixing shearing arm of force, so can be laborsaving during shearing.In addition, the contact range of Baltimore groove cutting edge and branch is big during shearing, so shearing force is relatively more balanced, can not tear bark, squeezes and hinders the branch interior tissue.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described: Fig. 1 is the structural representation of first kind of embodiment of the laborsaving branch scissors of the utility model.
Fig. 2 is the structural representation of second kind of embodiment of the laborsaving branch scissors of the utility model.
Fig. 3 is the structural representation of the third embodiment of the laborsaving branch scissors of the utility model.
Fig. 4 is the structural representation of the 4th kind of embodiment of the laborsaving branch scissors of the utility model.
Embodiment
As shown in Figure 1, this laborsaving branch scissors is hinged together by the pin 5 that is hinged by two cross one another scissor bodies 2, and this pin 5 that is hinged adopts bolt, nut structure.Be respectively equipped with handle 1 and scissors blade 4 on two scissor bodies 2, between two scissor bodies 2 that are hinged between pin 5 and two handles 1, the spring 6 of dehiscing be housed.The scissors blade 4 of scissor body 2 is curved, and the blade on one of them scissor body 2 is convex, and the blade of another scissor body 2 then is arcs of recesses.The scissors blade 4 of scissor body 2 is provided with a Baltimore groove cutting edge 3 again, and the Baltimore groove cutting edge 3 of this embodiment is semicircular arc.Branch places the Baltimore groove cutting edge 3 of this semicircular arc during use, then outwards slippage of branch, and its scissors arm of force and moment can so very branch is sheared in the labour-saving, and can not tear bark, not squeezed and hinder branch because of slippage strengthens.
Other structure of laborsaving branch scissors shown in Figure 2 is same as the previously described embodiments.But the scissors blade 4 of its arbitrary scissor body 2 is provided with the Baltimore groove cutting edge 3 of two arcs.An one Baltimore groove cutting edge 3 is used to shear thicker branch, so it is near the pin 5 that is hinged; Another Baltimore groove cutting edge then is used to shear thinner branch, and this is used to shear the outside that is positioned at another Baltimore groove cutting edge 3 than the Baltimore groove cutting edge 3 of thin branch.
Laborsaving branch scissors as shown in Figure 3 is respectively arranged with two relative arc Baltimore groove cutting edges 3 on the scissors blade 4 of two scissor bodies 2.When shearing branch with two arc Baltimore groove cutting edges 3 that are oppositely arranged and lay respectively on the different scissor bodies, the shearing force that branch is subjected to is balanced more, and the branch otch is more intact, and branch is more difficult to be squeezed, to damage.
In laborsaving branch scissors shown in Figure 4, the cutting edge of the Baltimore groove cutting edge 3 of the scissors blade 4 of scissor body 2 is that two-fold is linear.
It is preferred embodiment several below only to have enumerated the laborsaving branch scissors of the utility model, but the utility model is not limited thereto.Baltimore groove cutting edge as described is not limited in curved edge and the linear cutting edge of two-fold, can also be versions such as tri linear shape cutting edge or many broken lines shape cutting edge; Selling 5 and also be not limited to bolt nut structure, can also be other structures of shipping and reselling on another market commonly used; Remove on the scissors cutting edge 4 and can be provided with one or two Baltimore groove cutting edge, can be provided with as the case may be three more a plurality of; Or the like.Therefore, as long as the scissors blade is provided with the Baltimore groove cutting edge and all should be considered as falling into protection domain of the present utility model.
