Self-power-generating energy-saving pruning shear

Abstract

The invention discloses a self-power-generating energy-saving pruning shear, comprising a first rotating arm and a second rotating arm which are hinged to each other, and the first rotating arm and the second rotating arm are provided with a first cutting edge and a second cutting edge. First springs are arranged on hand-held portions, the first rotating arm is provided with a power generating component, the second rotating arm is provided with a curved rack, and the first rotating arm is provided with a battery connected with the power generating component. A winding motor is disposed on thefirst rotating arm, a winding wheel is disposed on the winding motor, and a pulling rope is connected between the winding wheel and the second rotating arm. The first cutting edge is rotatably connected to the first rotating arm, the first rotating arm is provided with a limiting protrusion, and a second spring is disposed between the limiting protrusion and the first cutting edge. One side of therotation center of the first cutting edge abuts against the other side of the second spring and against the limiting protrusion, and the limiting protrusion is provided with a contact switch. This pruning shear not only achieves the requirements of light weight, but also enhances the endurance ability and achieves the purpose of saving energy.

Description

technical field [0001] The invention belongs to the technical field of branch pruning tools, in particular to a self-generating energy-saving pruning shears, which are used for pruning fruit trees and gardening branches. Background technique [0002] Pruning shears are tools used for fruit tree branch pruning and garden tree branch pruning. The most commonly used pruning shears are similar to scissors, including two rotating arms that are hinged to each other. One side of the two rotating arms at the hinged position is a cutting edge that cooperates with each other, and the other side is a handle, usually between the two handles. There is a spring that pops up the rotating arm between them. This kind of pruning shears is light in structure, easy to carry and easy to operate. This kind of pruning shears is easy to prune thin branches, but it is very laborious when pruning thick branches, even because of lack of strength. It is impossible to cut off thick branches, and it is ...

Problems solved by technology

The most commonly used pruning shears are similar to scissors, including two rotating arms that are hinged to each other. One side of the two rotating arms at the hinged position is a cutting edge that cooperates with each other, and the other side is a handle, usually between the two handles. There is a spring that pops up the rotating arm between them. This kind of pruning shears is light in structure, easy to carry and easy to operate. This kind of pruning shears is easy to prune thin branches, but it is very laborious when pruning thick branches, even because of lack of strength. Unable to cut off thick branches, overall laborious when pruning both thick and thin branches

[0003] In order to make pruning shears more labor-saving, especially when pruning thick branches, electric pruning shears have appeared. Existing electric pruning shears generally include fixed blades, rotating blades, driving mechanisms, and battery components or power cords. One of the components, if the battery is used to provide power to the drive mechanism, the battery life is poor or the weight of the battery is large, which will cause inconvenience in use; while the power cord component directly connected to the circuit requires a very long power cord, which is not suitable for outdoor orchards Use of other places
