Abstract

The utility model relates to a pair of electric scissors. A blade of the utility model is composed of a fixed blade and a movable blade, wherein, the movable blade can be in a sawtooth shape and can also be in a shape without teeth. The motive power of the pair of electric scissors is an electromotor or an electromagnetic swinging device. A motive power transmission device is a rocking connecting rod, the middle of the connecting rod is provided with a rotating shaft, one end of the connecting rod shifts the movable blade by a shifting pin so that the movable blade and the fixed blade do relative motions to form shearing movements.

Description

Electric scissors

The utility model relates to a kind of cutting implement-electric shear, mainly is applicable to the shearing of thin slice class material such as cloth and silk, paper, leather, plastic sheeting etc.

The general scissors that uses, primary structure is linked with axle by two similar blades that have handle.Its shear history is to rely on manpower to do reciprocal action according to lever principle.Its deficiency is: the first, since manual operation, user's susceptible fatigue; The second, shear length and be difficult to grasp; The 3rd, except that shearing forward, the shearing of all the other directions is especially returned and is cut, comparatively difficulty; The 4th, safe not to the utmost when operating or carrying, the body or decrease his thing of easily hurting sb.'s feelings.

The utility model is intended to overcome deficiency of the prior art, and a kind of labour-saving, electric shear dexterous, safety are provided, to reach the existing unapproachable purpose of scissors.

Because knife cut frequency of the present utility model is higher, whenever finish a shear action and the material that is sheared is less, so the power consumption of shearing is less.As long as the operator presses telegraph key, the circuit that scissors is sheared to need advances gently, can reach satisfied shear effect.

Release of the present utility model is based on following art designs.When it used motor-driven, peace one excentric sleeve on motor shaft utilized excentric sleeve to drive one and shakes connecting rod, and the other end that shakes connecting rod drives one movable blades, and movable blades is reciprocating within the specific limits, thereby finishes shear action with fixed blade.The utility model also can adopt electromagnetic pendulum device to replace above-mentioned motor driver to finish same shear action.The cutting edge of scissors both can be zigzag, also can be no profile of tooth.

For visual understanding flesh and blood of the present utility model, special description of drawings is as follows.

Fig. 1 is the schematic diagram of electric shear.

1 is the fixed blade of electric shear among Fig. 1, and it forms triangle and dehisces, and dehiscing up and down, both sides are the edge of a knife.Fixed blade dehisce both sides when shearing successively as a side of the scissors edge of a knife.Guider when fixed blade dehisces to be simultaneously shearing again.

2 is movable blades of electric shear among Fig. 1, and it can be zigzag, and sawtooth two is to all there being cutting edge, and with the cutting edge formation scissor construction of fixed blade, movable blades clocklike moves back and forth, and can shear.Movable blades also can be made no profile of tooth, and it relies on the wobbling action that motor transmits and make movable blades play dissection under the guiding of fixed blade.

3 is pivot pins of stirring movable blades among Fig. 1.

4 is the rotating shafts that are fixed on the connecting rod of handle front portion among Fig. 1, and it plays the pivotal role of connecting rod low-angle rotation.

5 is connecting rods among Fig. 1.There is a chute its rear end, and the excentric sleeve (or calutron) on the power supply arbor is swung in certain reciprocating motion scope.This swing of rod rear end makes the connecting rod front end do rightabout swing by having the connecting rod of rotating shaft, forms the shear action of scissors with this.

6 is power set among Fig. 1.It can be a motor, also can be electromagnetism reciprocally swinging mechanism.Its power source can be a dc-battery, also can be the AC and DC external power supply.

7 is excentric sleeves among Fig. 1.When power set were motor, it was fixed on the axle of motor, plays the effect that makes connecting rod swing.

8 is power switches among Fig. 1.

9 is handles of electric shear among Fig. 1, but also double as battery case.

10 is the directed gathering sills that move of movable blades among Fig. 1.

Fig. 2 is the enlarged diagram of zigzag movable blades, and the both sides of each tooth are cutting edge, forms the scissors shape with fixed blade.

Claims

1, a kind of electric shear that is used to shear slim soft thing, it is characterized in that: the blade of scissors is made up of fixed blade and movable blades, and fixed blade is installed in the handle front end, and movable blades pastes mutually with fixed blade, and guider is arranged.

2, electric shear as claimed in claim 1 is characterized in that: the action of movable blades is reciprocating finishing by the excentric sleeve drivening rod of motor.

3, electric shear as claimed in claim 1 is characterized in that: power source is dc-battery or power of alterating and direct current.
