Abstract

The invention discloses a multifunctional branch pruning device with a replaceable tool bit. The multifunctional branch pruning device with the replaceable tool bit solves the problems that an existing branch pruning device requires an operator to ascend a height and is single in function. The multifunctional branch pruning device with the replaceable tool bit is characterized in that the multifunctional branch pruning device comprises an insulation operating rod, an internal thread connecting screw rod and the replaceable tool bit. The insulation operating rod is connected with the internal thread connecting screw rod, the internal thread connecting screw rod is in threaded connection with a replaceable tool bit sleeve pipe, and the replaceable tool bit is a multifunctional tool bit or a meniscus tool bit or a saw-type tool bit or a scissor-type tool bit. According to the multifunctional branch pruning device with the replaceable tool bit, the problem of safety distance for pruning branches is solved by using the insulation operating rod, and the multifunctional branch pruning device is a simple tool enabling people to achieve long-distance pruning on the branches on trees on the ground; according to the different varieties of trees and different environments, corresponding replaceable tool bits are used for carrying out pruning, the effect that the multiple functions of chopping, pruning, trimming and sawing are combined into a whole is achieved, using is convenient, labor is saved, cost is lowered, the personal safety factor in the tree pruning process is improved, and the safe operation of electric transmission lines in the tree pruning process is ensured.

Description

The multi-functional branch trimmer of interchangeable bit

Technical field

The present invention relates to a kind of tree trimmer, particularly relate to a kind of for clearing up the pruner for tree of transmission line of electricity screen of trees along the line.

Background technology

How to clear up transmission line of electricity screen of trees along the line is a difficult problem that is perplexing transmission line of electricity operations staff always, when the distance between power high-voltage line and trees surpasses the safe distance of regulation, high-voltage line will discharge to trees, in case of rain or air humidity excessive, under High Pressure, trees will become electric conductor, to trees building around, equipment, personnel can form harm, may cause substantial equipment, human casualty accident, cause huge loss not only to the country and people's lives and properties, also make electric power enterprise helplessly be involved among legal dispute and economic compensation simultaneously.Carry out now branch pruning work, must utilize ascending tool or free-hand climbing upper to tree, use axe and handsaw to prune, degree-of-difficulty factor is large, and risk is high, easily causes the generation of the accidents such as falling from high altitude, poisonous insect bite, electric shock.

Summary of the invention

The object of the invention is to overcome the multi-functional branch trimmer that the deficiencies in the prior art provide a kind of interchangeable bit, convenient, laborsaving, integrate and cut, cut, repair, saw multiple function, can use corresponding interchangeable bit to prune according to the difference of seeds and environment, guaranteeing has enough safe distances between tree and line, guarantees line security operation.

The invention is characterized in: comprise insulating bar, internal thread connecting screw rod, interchangeable bit, described insulating bar connects internal thread connecting screw rod, internal thread connecting screw rod screw joint casing; Described internal thread connecting screw rod is connected internal thread, sleeve pipe restriction nut, is protected pad connection internal thread, action bars internal thread to protect pad, action bars to connect internal thread and form by cutter head successively; Described interchangeable bit is Multifunctional tool bit, and lower end is tapped sleeve pipe, and upper end comprises eave tile, shovel head, reaping hook; The lower end of described shovel head, reaping hook, eave tile is welded on sleeve pipe together.

Described interchangeable bit is falcate cutter head, and upper end comprises scythe head, axe, and described scythe head, axe lower end are welded on sleeve pipe together.

Described interchangeable bit is the saw type cutter head with sawtooth, and the lower end of saw type cutter head is welded on sleeve pipe.

Described interchangeable bit is scissors-type cutter head, comprises cutter head, lower cutter head, between upper cutter head, lower cutter head, by pin, back-moving spring, is flexibly connected, and upper cutter head is welded on sleeve pipe, and the tail end of lower cutter head connects stay cord.

Described insulating bar is more piece, between every joint, is threaded.

As shown from the above technical solution, the present invention adopts insulating bar to solve the safe distance problem of tree trimming, is that a kind of people can realize the remote light instrument of pruning to the branch on tree on the ground; Head end to insulating bar improves, and can adopt screw-type to be connected with interchangeable bit, and parts can be linked together with insulating bar securely, and safety and reliability operates; Can, according to the difference of seeds and environment, use corresponding interchangeable bit to prune: Multifunctional shovel head is for upwards pruning and dispose the foreign matter dropping on wire; Falcate cutter head is used for pruning eminence branch; Saw type cutter head can be pruned compared with fat tree wood top, particularly approaches the branch of wire, has avoided branch to swing back and forth and has caused the phenomenon of by mistake touching wire; Scissors-type cutter head, controls blade clutch by stay cord, cuts off high-altitude branch, for high-altitude fruit tree and landscape tree and near the pruning of the branch of wire; Reach and cut, cut, repair, saw multiple function and be integrated, easy to use, laborsaving, and also cost-saving, improved personal safety coefficient in tree trimming process, guarantee transmission line of electricity safe operation in tree trimming process.
