The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Present embodiment is a kind of electric shear, and electric shear is a kind of of small hand-held electric tool.The utility model also is applicable to electric massager, Electric shoes rubber; All be that the functor that the power drives motor drives in the functional head of eccentric headband motivation body front end again moves reciprocatingly on these small hand-held electric tools, functor can be that blade, massage head, polishing-shoes are first-class etc.

Like Fig. 3, shown in Figure 5; The fuselage 100 of electric shear by about two

housings

14,15 fasten and form, be equipped with motor 5 in the fuselage 100, motor 5 correspondences are provided with motor switch 1; The output shaft of motor 5 connects reductor 6; Be arranged with an off-centre 8 on the output shaft of reductor 6, be arranged with motion square 9 on eccentric 8 the eccentric part, motion square 9 embeds in the set horizontal breach in swing components 11 rears; The upper and lower side of swing component 11 is embedded in the swing component guide groove 10, and there is swing component draw-in groove 110 in the place ahead of swing component 11.

Be connected with battery spring lamination 3 behind the motor 5, motor 5 contacts with power supply to obtain driving through battery spring lamination 3.The inwall at the rear portion of fuselage 100 is provided with grab groove 262, and grab groove 262 is for power source body 26 is combined within the fuselage 100.

Power source body 26 can have two kinds of forms, and a kind of form such as Fig. 6 are shown in Figure 7; The shell of power source body 26 is fastened by upper casing and lower casing and forms, and is provided with briquetting 261 in the both sides of power source body 26, and the end of briquetting 261 has grab 2610; Two briquettings 261 all are connected on the elastic construction 263, and the front end of grab 2610 can be made skewed, like this; Directly power source body 26 is inserted fuselages 100, briquetting 261 will be out of shape a little and presses down, and arrives grab grooves 262 positions up to grab 2610; Briquetting 261 meeting resiliences, the grab 2610 of briquetting 261 just is stuck on the grab groove 262 of fuselage 100, and is as shown in Figure 3 thereby power source body 26 is placed in the fuselage 100.Be equipped with nickel-hydrogen chargeable cell 27 in the power source body 26, nickel-hydrogen chargeable cell 27 installs that the back contacts with battery spring lamination 3 shown in Figure 5 and can drive motors 5 at power source body 26.

As shown in Figure 8, power source body 26 can be with the direction of arrow to pressing down briquetting 261 after nickel-hydrogen chargeable cell 27 does not have electricity, and power source body 26 is pulled up in fuselage 100, uses charger 28 chargings that are inserted with DC plug 29 then.

Because use rechargeable battery, the utility model uses more environmental protection, and needn't connect DC plug 29 always, use more convenient flexible.

But; (for example use up under the situation that has little time to charge) in some cases at battery; At this time can use the power source body 26 of second kind of form, like Fig. 9, shown in Figure 10; Structures such as the housing of power source body 26, briquetting 261 are identical with the power source body 26 of above-mentioned first kind of form with occupation mode; Difference has been to install in the power source body 26 DC socket 30 that directly can insert DC plug 29, and after power source body 26 was installed in the fuselage 100, DC socket 30 contacted with battery spring lamination 3 shown in Figure 5 and can drive motors 5.

The power source body 26 of above-mentioned two kinds of forms make the utility model can flexible Application in the different working occasion.

As shown in Figure 4; The cutter head 16 of the utility model is fastened with right shell body 18 by left shell 17 and forms; On left shell 17 and right shell body 18, all be provided with the anti-skidding position 25 of concave-convex surface structure; Be installed with motionless bottom knife 22 in the cutter head 16, thereby a cutter 21 compresses suitably and hinged formation scissors through hinge 19 and spring 20 and bottom knife 22, the rear end of cutter 21 is installed with a upper slitter and inserts 23; Insert 23 size of upper slitter is can be embedded in the swing component draw-in groove 110 of above-mentioned swing component 11; It 23 is arc bodies that upper slitter is inserted, so moving up and down of swing component 11 can make upper slitter insert 23 can to roll when in swing component draw-in groove 110, moving up and down, cause cutter 21 to rotate around hinge 19 like this.

As shown in Figure 5, slide in the chute of the front end top of fuselage 100 and be provided with a cutter head block 13, be provided with spring 12. between cutter head block 13 and the fuselage 100

Like Fig. 4, shown in Figure 2, the top of cutter head 16 is provided with a shelves groove 24.

During the actual installation cutter head; Take fuselage 100 on the other hand, pinch the anti-skidding position 25 (hand tries not to run into blade) on the cutter head 16 with thumb and forefinger on the other hand, cutter head 16 is aimed at fuselage 100 insert; Need not painstakingly note upper slitter insert 23 whether aimed at swing component 11 draw-in groove 110; Cutter head block 13 can be by the upper surface of cutter head 16 to pusher such as Fig. 2 direction of arrow in the insertion process, and shelves groove 24 positions on the front end of cutter head block 13 and cutter head 16 are at once, and cutter head block 13 can reset under spring 12 effects; Thereby the end of cutter head block 13 inserts in the shelves groove 24; At this moment upper slitter is inserted and 23 also inserted in the swing component draw-in groove 110 of swing component 11, thereby cutter head 16 is connected like Fig. 1 with fuselage 100, and is shown in Figure 3.

Because cutter head block 13 can stretch and reset; So in installation process, played the guiding positioning action; No matter upper slitter is inserted and 23 is which kind of angle or height with swing component 11, as long as rough alignment needs only cutter head block 13 and resets; The end of cutter head block 13 inserts in the shelves groove 24, and the relative position of each parts just is fixed up accurately.

Unload cutter head 16, as long as a handgrip cutter head block 13 makes its terminal shelves groove 24 that breaks away to pushing back like Fig. 2 direction of arrow, the anti-skidding position 25 that the thumb of another hand and forefinger pinch cutter head 16 is outwards extracted cutter head 16 and is got final product.

It is thus clear that the utility model loading and unloading cutter head 16 does not need instrument, and when cutter head 16 is installed as long as rough alignment is very convenient.

As shown in Figure 3, when the utility model uses, press motor switch 1; Power source body 26 gives motor 5 power supplies; Motor 5 drives eccentric 8 rotation through reductor 6, and eccentric 8 eccentric part drives motion square 9 and converts circular motion rectilinear motion into and drive swing component 11 and in swing component guide groove 10, move up and down, and the swing component draw-in groove 110 interior upper slitters of swing component 11 are inserted and 23 just moved up and down; Thereby cutter 21 rotates around hinge 19, accomplishes shearing work in conjunction with motionless bottom knife 22.
