High altitude scissors

Abstract

High-altitude scissors comprise a holding rod and a fixing frame which is in invert L shape and comprises a hook which is formed by fixing part and self-fixing part by bending and extending, one end of the hook is fixed on the holding rod; the two ends of a shear blade are cutting edges; a first and second pin holes are set on two cutting edges respectively, cutting edge is movably connected to the fixing part of the fixing frame by one of the two pin holes; the cutting edge of shear blade is cooperated with the hook of the fixing frame; a pull rope is connected with one end of the shear blade. The invention designs high-altitude scissors to have cutting edges at the two ends. During operation, if one cutting edge gets blunt, the connection piece and blade are only needed to be separated, and the blade is switched towards the other direction to use standby blade for freely shearing. At the same time, the design of connection piece increases the force arm to lead shearing to be more labor-saving. Moreover, connection piece is made into protective case type to hide the standby blade, which extends the service life of product and prevent standby blade from the accidental injury to operator.

Description

technical field [0001] The invention relates to a pruning tool for gardening, in particular to high-altitude shears for pruning high branches. Background technique [0002] The high-altitude shears that existing people are used for the pruning of high branches all are that a blade rotates around the cutter head to form cutting under the traction of chain or rope, adds a detachable saw blade. [0003] As we all know, after a period of use of knife products, the blade will become blunt, making it very laborious to cut the knife in the future, especially when cutting wet branches, the plant epidermis will secrete a viscous liquid, which will stick to the blade. Easily dulls the knife edge. [0004] In addition, the blades of these blades all need special tools for grinding. Generally, users cannot sharpen the blades themselves. Once they are not well ground, they cannot be used in the future. Contents of the invention [0005] In order to improve the service life of the pro...

Problems solved by technology

[0003] As we all know, after a period of use of knife products, the blade will become blunt, making it very laborious to cut the knife in the future, especially when cutting wet branches, the plant epidermis will secrete a viscous liquid, sticking to the blade, and more Easily dulls the edge of the knife

[0004] In addition, the blades of this kind of blades need to be sharpened with special tools. Generally, users cannot sharpen their own knives. Once they are not well ground, they cannot be used in the future.
