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
The present invention relates to a kind of gardening pruning tool, particularly be used for the high altitude scissors of the pruning of high branch.
Background technology
The high altitude scissors that existing people are used for the pruning of high branch all is that a blade rotates the formation cutting around cutter head under the traction of chain or rope, adds a demountable saw blade.
As everyone knows, the cutter series products in use for some time, blade all can rust, makes to require great effort very much when shearing after the cutter, when particularly shearing wet branch, plant epidermis can secrete the liquid of thickness, is bonded on the blade, the easier edge of a knife rust that makes.
In addition, the blade of this blade all needs the specific purpose tool grinding, and the user can not oneself whet a knife generally speaking, in case grind badly, all can't use later on.
Summary of the invention
In order to improve the service life of product, improve the above-mentioned defective that existing product exists, the objective of the invention is to design a kind of high altitude scissors, shear more laborsaving, longer service life.
For achieving the above object, technical scheme of the present invention is,
High altitude scissors, it comprises, holding rod; Comprise that also fixed mount is L shaped, comprise fixed part and the hook part that extends to form from the fixed part bending, the one end is fixed in holding rod; The fixed part upper end has pin-and-hole; Shear-blade, its body two side ends is established blade, and accordingly, the blade body of its two blades side is respectively equipped with first, second and connects pin-and-hole, and connects pin-and-holes by these two and select one and connect with the activity of fixed mount fixed part; Shear-blade blade and the corresponding cooperation of fixed mount hook part; Stay cord is connected in shear-blade one end.
Further, high altitude scissors of the present invention also comprises, brace, one end are fixedly connected on shear-blade one end; The other end connects a spring, and the other end of this spring is connected in fixed mount; Stay cord is connected in this brace the 3rd end; Also symmetrical respectively offering for first, second connecting hole that connects brace on the described shear-blade, correspondingly, brace has connecting hole.
Further, high altitude scissors of the present invention also comprises, fixed pulley is connected in brace the 3rd end by support; Chain, one end are fixed on the fixed pulley support, and the other end is walked around the connecting rod that is positioned at the fixed mount fixed part, pass fixed pulley again and are connected with stay cord.
Again, described first and second connection pin-and-hole protrudes in described shear-blade outer peripheral edges.
In addition, described fixed mount has the guide groove that runs through vertically, and a side of shear-blade is arranged in this guide groove.
Establish in the described fixed mount fixed part guide groove can the backstop shear-blade position limiting structure of upset.
Described position limiting structure connects pin-and-hole or second with first of described shear-blade outer peripheral edges and connects the corresponding cooperation of pin-and-hole.
Have, have the groove that is complementary with shear-blade one side profile on the side end face of brace of the present invention, when a side tool sword of shear-blade was in off working state, this side tool sword was embedded at this groove.
Described brace is the protection nested structure, and the blade of a side off working state of shear-blade inserts in this brace.
The present invention also is provided with a saw blade, and this saw blade one end is fixed in described fixed mount.
Have on the described saw blade for connecting the fixedly hole clipping and the connecting pore of usefulness.
Described holding rod is the extension type structure, comprises dead lever, is inserted in the motion bar in the dead lever and fixes the fixture of this two bar.
Described fixture comprises locking member, following locking member, is connected and fixed bar, motion bar respectively; Upper and lower locking member threaded engagement is fixed.
Beneficial effect of the present invention
The present invention is two blade with the insert design of high altitude scissors, in use, on one side after the edge of a knife rust, the user only need separate brace and blade, blade is changed a direction,, use standby blade just can easily shear because two blade and connecting hole are designed to the center symmetry.
Simultaneously, specialized designs of the present invention brace, its major function is to increase the arm of force; make shearing more laborsaving, brace is made the protection shell type simultaneously, and standby blade is stashed; prolonged the service life of product, prevented that also standby blade from causing accidental cuts to the user.
