Abstract
Insulating tree shears comprise an insulating rod. A lower shear is arranged at the top end of the insulating rod. An upper shear and a pressure handle are hinged to the lower shear. A torsion spring is arranged between the pressure handle and the lower shear. The pressure handle is meshed with the upper shear through gear teeth. A moving pulley block is disposed at the tail end of the pressure handle. A fixed pulley block is arranged on the insulating rod. A pull cord is disposed on the insulating rod and passes through the moving pulley block and the fixed pulley block. The lower shear is provided with teeth, and a cutting edge is arranged on one side of the teeth. The insulating rod effectively prevents electric shock. The moving pulley block increases pulling force, the pressure handle is connected with the upper shear by meshing of gear teeth high in transmission efficiency, the shearing force is large, and accordingly the insulating tree shears are easy to operate, convenient for trimming, and available for shearing thick branches.
Description
Technical field
The present invention relates to the insulation trees scissors used in a kind of operations involving high pressure.
Background technology
In electric operating process, the branch of large tree can disturb staff's operation.For convenience of staff's operation, trees scissors need be used branch to be wiped out.
Existing trees scissors comprise wooden long handle, and wooden long handle is provided with down cut body, and down cut is hinged with spliced body, are provided with torsion spring between described upper spliced body, down cut body, are provided with stay cord at upper spliced body end.
During use, upper spliced body and down cut body open under the effect of torsion spring, pull stay cord, make spliced body, down cut body closes up, cut off branch.
The defect of this trees scissors is: 1 due to the material of long handle be wooden, conductor can be become when the air humidity such as overcast and rainy is large, near transmission line of electricity, easily electric shock accidents occur.Use simple cylinder bar to complete shearing, staff uses effort, and shearing force is little, not easily cuts off branch.3, when branch is thicker, the sword face of scissors is difficult to cut off branch, and firmly excessive, and scissors can be caused to collapse folding.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can ensure staff's personal safety, rapid operation, and beta pruning is insulated trees scissors easily.
The present invention is achieved in that
A kind of insulation trees scissors, comprise the insulation body of rod, down cut body is provided with on the top of the insulation body of rod, its special character is: on down cut body, be hinged with spliced body and pressure handle, torsion spring is provided with between described pressure handle and down cut body, gear teeth meshing is passed through between described pressure handle and upper spliced body, running block is provided with at pressure handle end, the insulation body of rod is provided with fixed pulley group, the body of rod is provided with stay cord, described stay cord passes by running block, fixed pulley group, and down cut body is provided with teeth, and the side of described teeth is sword face.
Be provided with two movable pulleys in described running block, be provided with two fixed pulleys in described fixed pulley group, described stay cord passes a movable pulley successively, a fixed pulley, another movable pulley, another fixed pulley.
Described running block is provided with door, to protect running block.
Upper spliced body is provided with teeth, and the teeth on described upper spliced body, down cut body tilt and incline direction is consistent.
The invention has the beneficial effects as follows:
1, owing to being provided with the insulation body of rod, effectively prevent the generation of electric shock accidents;
2, owing to being provided with teeth, can THE ADIABATIC SHEAR IN branch, and can avoid causing insulation trees scissors to collapse folding because branch is too thick.
3, owing to increasing pulling force by running block, and adopt the mode of the high gear teeth meshing of transmission efficiency to connect pressure handle and upper spliced body, shearing force is large, rapid operation, and beta pruning is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the connection diagram of stay cord.
In figure: the body of rod 1, stay cord 2, fixed pulley group 3, down cut body 4, torsion spring 5, upper spliced body 6, pressure handle 7, running block 8, door 9, teeth 10.
Detailed description of the invention
As shown in the figure, these insulation trees scissors comprise the body of rod 1, down cut body 4 is provided with on the top of the body of rod 1, down cut body 4 is hinged with spliced body 6 and pressure handle 7, torsion spring 5 is provided with between described pressure handle 7 and down cut body 4, gear teeth meshing is passed through between described pressure handle 7 and upper spliced body 4, running block 8 is provided with at pressure handle 7 end, running block 8 is provided with door 9, the body of rod 1 is provided with fixed pulley group 3, the body of rod 1 is provided with stay cord 2, two movable pulleys are provided with in described running block 8, two fixed pulleys are provided with in described fixed pulley group 3, described stay cord 2 is successively through a movable pulley, a fixed pulley, another movable pulley, another fixed pulley.Upper spliced body 6, down cut body 4 are respectively equipped with teeth 10, and the teeth 10 on described upper spliced body 6, down cut body 4 tilt and incline direction is consistent.
During use, upper spliced body 6 is positioned at open configuration with down cut body 4, and pull stay cord 2, pressure handle 7 presses down, and is depressed by upper spliced body 3, shears branch.
