Scissors for fruit trees

Abstract

The invention discloses a kind of scissors for fruit trees, which comprises a lock, a scissor handle, a telescopic device, a blade back, a friction surface, a blade, a balance surface, an inner surface, an outer surface, an outer inclined surface, a hexagonal screw, a support point, a gasket, and a nut , a spring and a blade, the lock is located on the scissor handle, the two ends of the spring are respectively located on the scissor handle, the telescopic device is located on the scissor handle, the blade is located on the scissor handle, the blade, the outer surface, The inner surface, the balance surface and the knife back constitute the blade, the hexagonal screw is fixed on the supporting point through a nut, and the spacer is located under the hexagonal screw. The direct distance between the support point and the scissor handle of the scissors of the present invention is increased, which is equivalent to shortening the resistance arm of the lever, and the labor-saving effect is more obvious. The height of the branches makes the performance of the fruit tree pruning shears significantly improved.

Description

technical field [0001] The invention relates to the technical field of gardening tool parts, in particular to scissors for fruit trees. Background technique [0002] Existing fruit tree pruning shears are made up of two crossing levers, the crossing point is a rotating shaft, the two sections of lever resistance arms in front of the rotating shaft have a blade, and the force arms of the two ends of the rotating shaft behind the levers are two handles. Common sense in mechanics shows that when scissors cut branches, the closer the pressure point of the blade to the branch is to the support point, that is, the closer to the rotating shaft, the less effort is required. Therefore, the distance from the rotating shaft to the blade should be shortened as much as possible, but the closer the distance between the rotating shaft and the blade , the guide operation between blade and blade is smaller, and it is easy to jam knife, and existing fruit tree pruning shears cannot stretch, a...

Problems solved by technology

[0002] Existing fruit tree pruning shears are made up of two crossed levers, the intersection point is a rotating shaft, the two sections of lever resistance arms in front of the rotating shaft have a blade, and the force arms of the two ends of the rotating shaft behind the levers are two handles. Common sense in mechanics shows that when scissors cut branches, the closer the pressure point of the blade to the branch is to the support point, that is, the closer to the rotating shaft, the less effort is required. Therefore, the distance from the rotating shaft to the blade should be shortened as much as possible, but the closer the distance between the rotating shaft and the blade , the smaller the guiding operation between the blade and the blade, the easier it is to jam the knife. The existing fruit tree pruning scissors cannot be retracted and cannot cut to higher branches, which increases the difficulty of pruning
