The upper blade and the lower blade are provided with inner blades and outer blades.
The rod body is a straight rod, can also be an L-shaped rod or an arc-shaped rod, in order to realize the best transferability, the middle part of the rod body is provided with clamping rings at intervals, each clamping ring is an open circular ring, and the periphery of each circular ring is fixed with the inner wall of the rod body through a support.
According to the technical scheme, the fruit tree pruning tool is simple in structure, convenient to manufacture and use, the fixed handle and the movable handle are held by one hand, the rod body is held by the other hand, and then the knife edge can be extended to points which are difficult to reach, such as high positions, deep positions and the like of fruit trees to prune the fruit trees.
The technical scheme has the following beneficial effects:
1. two sides of the upper blade are provided with no less than two groups of guide structures, so that the upper blade is ensured to be stably translated, and one side of the upper blade is prevented from being inclined to generate a lever phenomenon in the process of pruning;
2. the spring is used for enabling the upper blade to automatically return when the upper blade is not under the force of the rope, so that the reciprocating use is convenient;
3. this scheme provides two kinds of laborsaving transmission: the transmission device with the pulley realizes labor saving by forming a lever because the fixed point of the steel rope is closer to the fulcrum; the transmission device with the one-way bearing and the gears can realize different labor-saving effects by arranging the gears with different sizes;
4. this device simple structure, the body of rod can set up very thinly, and the scissors can set up very little, is convenient for extend to the knife head easily to the appointed point that ordinary arm is difficult to reach, like luxurious grape vine frame. Meanwhile, the rod body can be arranged into an L shape or an arc shape, and the rod body is only required to be provided with the clamping rings at intervals, and the steel rope is embedded from the opening of the clamping rings;
5. the upper blade and the lower blade are both provided with an inner blade and an outer blade, can be used as scissors, can also be used as a sickle and a small-sized Go tool to cut and puncture branches, and the outer blade is provided with sawteeth when necessary.
