Technical Field

[0001] The utility model relates to the field of pruning, in particular to a low-resistance bark-damage-proof fruit tree scissor blade. Background Art

[0002] Fruit tree pruning is an important part of orchard management. Pruning can remove diseased and weak branches, dead branches, and crossed branches on fruit trees, which greatly reduces the occurrence and spread of diseases. It also helps to improve the ventilation and light conditions of the tree body and reduce the occurrence of insect pests. Scissors are the focus of tree pruning, but the existing bark scissors do not consider the impact of the bark scissors on the bark when they are used, which makes the effect of the bark scissors when used unfavorable.

[0003] For example, Chinese patent CN216146789U discloses an improved electric pruning shears, including a casing, a battery pack, a motor, a gear box, a control circuit and a blade assembly. The fixed blade is arranged opposite to the blade of the common electric pruning shears, so that it is more suitable for right-handed users and reduces the tearing of bark during the shearing process. However, the contact area of ​​the bark scissors blade when cutting branches is not considered when using the above-mentioned bark scissors blade, which makes the convenience of the bark scissors blade unsatisfactory when used.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a low-resistance bark-damage-proof fruit tree scissors blade to overcome the above-mentioned technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A low-resistance, anti-injury bark fruit tree scissors blade comprises an upper cutting blade, a lower cutting blade is arranged at the bottom of the upper cutting blade, and the upper cutting blade matches the lower cutting blade.

[0008] Furthermore, in order to facilitate the cutting of branches by the shearing blade, a first assembly hole is provided at one end of the shearing blade, an arc-shaped cutting surface is provided at the other end of the shearing blade, a first adjustment hole is provided between the arc-shaped cutting surface and the first assembly hole, and a plurality of cutting grooves are provided on the top of the arc-shaped cutting surface.

[0009] Furthermore, in order to facilitate the limited cutting of branches by the shearing lower blade, the shearing lower blade includes a limiting knife disc arranged at the bottom end of the shearing upper blade, a second assembling hole is opened at one end of the limiting knife disc, a second adjustment hole is opened outside the circumference of the second assembling hole and located at the top of the limiting knife disc, a clamping arc surface is opened on one side of the limiting knife disc, a limiting block is arranged on the top of the clamping arc surface, and a protective arc surface is opened on the other side of the limiting knife disc.

[0010] Furthermore, in order to facilitate installation and connection of the shearing upper blade and the shearing lower blade, the first assembly hole is connected to the second assembly hole, and the first adjustment hole is matched with the second adjustment hole.

[0011] The beneficial effects of the utility model are:

[0012] 1. By cooperating with the upper shear blade and the lower shear blade, the upper shear blade and the lower shear blade are combined into a scissors blade to shear branches, thereby improving the shearing efficiency of branches. At the same time, by opening a cutting chute on the top of the arc-shaped cutting surface and using the V-shaped shearing direction of the upper shear blade and the lower shear blade, the cutting chute greatly reduces the contact area between the branch and the upper shear blade when shearing the branch, thereby reducing the shearing friction and improving the efficiency and service life of the scissors blade when in use.

[0013] 2. By setting a limit knife disc, using the cooperation of the upper shear blade and the lower shear blade, the clamping arc surface supports the branch, and as the upper shear blade and the lower shear blade cut, the limit card block penetrates into the branch, and the clamping arc surface is used to reduce the angle between the branch and the lower shear blade, so that the bark is pushed into the groove formed by the limit card when cutting, thereby reducing the squeezing of the bark and greatly reducing the damage to the bark caused by the upper shear blade and the lower shear blade when cutting the branch.
