The upper end of the cylinder shaft is provided with a spring and a rotation arm is arranged below the spring. The two ends of the rotation arm are provided with a left telescopic cutter frame and a right telescopic cutter frame. The lower end of the right telescopic cutter frame and the lower end of the left telescopic cutter frame are provided with a right cutting knife and a left cutting knife. The lower end of the center hollow cylinder shaft is provided with a box-type center cone. A motor and a battery are installed in the box-type center cone. A motor shaft is installed in the center hollow cylinder shaft and connected with the rotation arm through a worm wheel and a worm. The double-end power-driven round material utility knife can rapidly cut needed round materials in a standard mode and save time and labor.

Description

Under Double-end motor-driven, circular material is drawn cutter

Technical field

The present invention relates to circular material under a kind of Double-end motor-driven that can fly-cutting go out required circular material driving with dc source and draw a cutter.

Background technology

At present, people, when installation exercise, often need to cut small-sized soft rounded material, with lancinating or cutting with scissors, result is to waste time and energy, and cuts the fenestra cutting nonstandard, waste material and do not reach requirement and object, with machinery, having become low load with strong power, losing more than gain.

Summary of the invention

In order to solve the problem of above-mentioned proposition, the invention provides under a kind of Double-end motor-driven circular material and draw a cutter, under this Double-end motor-driven, circular material is drawn a cutter, the rounded material that can fly-cutting goes out to need, time saving and energy saving standard again.

The object of the present invention is achieved like this, under Double-end motor-driven, circular material is drawn cutter, empty cylinder axle top, center is horizontal lever, spring is housed outside upper end, under spring, it is turning arm, a telescopic left side is equipped with at turning arm two ends, right knife rest, left, a left side is equipped with in the lower end of right knife rest, right cutter, Kong Tongzhou lower end, center is provided with box center cone, in box center cone, motor is housed, battery, motor shaft is contained in the empty cylinder axle of center and adopts Worm-gear type to be connected with turning arm, during use, with regulating gim peg to regulate the size of making cut garden of left and right knife rest, box center cone is fixed on and will cut Yuan center, with hand, live horizontal lever, start motor, the motor shaft driven rotary arm of rotation, left, right blade holder turns, left, right cutter is with a left side, during right blade holder turns, cut required round piece.

Feature of the present invention is, rational in infrastructure, practical and convenient, is the good assistant during people work.
