Abstract

The invention discloses an electric chain saw provided with a telescopic link which structurally comprises the telescopic link, a chain saw device, a chain saw frame and the like. The chain saw frame is internally provided with a matching device for integrally fixing a plurality of mini direct current motors with the chain saw device, the matching device is fixedly hinged with a chain saw connecting and switching device at the top of the telescopic link, a handle at the lower end of the telescopic link is provided with a supply hub and a switch, and the direct current motors which are led to the top form a cavity of the telescopic link are connected with one another by a lead wire. When the electric chain saw is used, a battery supply socket which is carried on the shoulder of a user is plugged into the supply hub, the end of the chain saw is hooked at the fork of a tree to draw the telescopic link, the upper part of the fork which needs to be sawn is aimed at the chain saw, a power switch is pressed, the chain saw is driven by the motors, and the fork of the tree can be easily sawn; therefore, the electric chain saw is labor-saving and time-saving, and can improve the work efficiency, thereby being an idea tool for the electric industrial workers to remove the high voltage/low voltage pipeline tree baffle and for the garden workers to shape the tree.

Description

The expansion link electric powered chain saw

Technical field

The present invention relates to the instrument that the rural power worker is used for the arrangement of power circuit passage tree branches, especially a kind of stock has the electric powered chain saw of Telescopic.

Background technology

Current development along with society, rural area high-low pressure electric power networks gathers, the problem that power circuit and spacing between the trees have become rural power worker to have a headache the most, usually make the lead short circuit because of trees striking power circuit, ground connection, break the lead phenomenon, therefore burn power equipment, household electrical appliance and cause human casualty accident, not only cause economic loss to power supply enterprise and user, and supply order is interfered, rural power worker can only only depend on a long sickle bar to be broken for the tree branches that influences the power circuit passage and dispose, also have many high not colluding, thick branch draws constantly, and hard large effect is poor.

Summary of the invention

The objective of the invention is to design a kind of simple structure, easy to operate, use laborsavingly, portable, have the retractility long electric powered chain saw of adjusting lever arbitrarily.

Technical scheme of the present invention is, it comprises expansion link, electromotor, the chain saw device, compositions such as chain saw framework, it is characterized in that, device has a small-sized DC motor in the described chain saw framework, the dc motor gear drive matches with the small-sized chain saw device, one joint square tube is arranged at chain saw framework bottom, the every face of square tube has two circular holes corresponding and equidistant with the opposite, the expansion link top is fixedly connected with one, " fourth " font connects conversion equipment, " fourth ' font connects on the square tube of conversion equipment lower end that two circular holes are arranged; with the corresponding rotating shaft fixing hole of two bolts; described jockey setting is by the fixed position of two bolts in circular hole; can adjust and make chain saw horizontal; vertically; put down to conversion, described expansion link is the cylinder that a side is the plane, last pitch plane is provided with equidistant brake hole, under save plane, top place brake device be set, described brake device is to make expansion link pull out the automaton that can not regain voluntarily, can only press the control button on the brake device during withdrawal, the lower end handgrip part is with insulation tube, penetrate in the described telescoping tube one with electromotor connect by lead, insulating sleeve lower end supply hub, power switch are arranged on the telescoping tube insulating sleeve, rechargeable battery is provided with to be worn, and line trap inserts in the supply hub of insulating sleeve lower end.

In sum, on one's body when using, accumulator being worn, adjust the occupation mode of chain saw as required, chain saw colluded on crotch can elongate expansion link, avoid pulling out long and lift not, chain saw is ridden on this branch of removing, press power switch, the motor drives chain saw rotates, and this branch is just amputated by easy to do, and is time saving and energy saving, increase work efficiency, these facility not only are applied to influence the cleaning of the other trees branch of high-low pressure power circuit, also are applicable to the finishing of ornamental trees and shrubs branch, are to carry trees branch refacer very easily.

Described expansion link electric powered chain saw expansion link is two merism devices, but the root demand of drawing together suitably increases its joint number, uses with convenient.

Described expansion link electric powered chain saw disposes a storage batteries repeatedly.
