In an embodiment, described power brick is provided with the buckle of self-contained battery bag therein, and described mount pad is provided with the draw-in groove matching with described buckle.

In an embodiment, the quantity of the draw-in groove on the buckle in described each power brick and described each power brick mount pad is 2 therein.

In an embodiment, described two buckles are located at the both sides of described power brick relatively therein, and described two draw-in grooves are located at the both sides of described power brick mount pad relatively.

In an embodiment, the end of described power brick is provided with the locating dowel of self-contained battery bag therein, in described power brick mount pad, is provided with the locating hole matching with described locating dowel.

In an embodiment, the cross section of described locating dowel is triangle or quadrangle therein, and the aperture of described locating hole and the cross section of described locating dowel correspond to triangle or quadrangle.

Above-mentioned electric tool is provided with at least two power brick mount pads, and this electric tool just can be installed at least two power brick simultaneously like this, thereby the flying power of this electric tool is at least doubled.In addition, the electric current that can provide due at least two power brick is at least twice of a power brick, so this electric tool can produce larger power, thereby increases work efficiency.

Accompanying drawing explanation

Fig. 1 is the electric tool schematic diagram of an embodiment;

Fig. 2 is the stereogram of the power brick of electric tool shown in Fig. 1;

Fig. 3 is the end view that power brick shown in Fig. 2 is connected with power brick mount pad.

The specific embodiment

Please refer to Fig. 1, an embodiment provides a kind of electric tool 100.This electric tool 100 comprises workpiece 110 and the driver part 120 that drives workpiece 110 to work.Driver part 120 is electrically connected with at least two power brick mount pads 130 mutually, and these at least two power brick mount pads 130 are in parallel together,, on circuit connecting relation, between these at least two power brick mount pads 130, is relation parallel with one another.On these at least two power brick mount pads 130, power brick 140 is all installed.Like this, on this electric tool 100, just there are at least two power brick 140.In this embodiment, power brick mount pad 130 is two with the quantity of power brick 140.This electric tool 100 can be electric drill, electric grinder, electric saw, grass-mowing machine etc.The workpiece 110 of this electric tool 100 can be drill bit, emery wheel, saw, grass-mowing machine head etc.The driver part 120 of this electric tool 100 can be motor etc.When this electric tool 100 is worked, the battery in power brick 140 provides the energy for this electric tool, and driver part 120 obtains can driving workpiece 110 to work after the energy, thereby realizes the function of this electric tool.

Please refer to Fig. 2 and Fig. 3, this power brick 140 is provided with buckle 142, and the quantity of the buckle 142 in each power brick 140 is 2 herein.These two buckles 142 are located at the both sides of power brick 140 relatively.Buckle 142 is for having flexible snap fit.

The power brick mount pad 130 of this electric tool 100 is provided with the draw-in groove matching with buckle 142.The quantity of the draw-in groove on each power brick mount pad 130 is also 2.Draw-in groove is located at the both sides of power brick mount pad 130 relatively.Buckle 142 in power brick 140 is the relation cooperatively interacting with the draw-in groove on power brick mount pad 130.When assembling, when power brick 140 is assembled on power brick mount pad 130, in power brick 140, match with the plug on power brick mount pad 130 for the jack 146 being electrically connected mutually with power brick mount pad 130, be that plug is inserted in jack 146, thereby reach the object of electric connection, make electric power supply in power brick 140 to this electric tool 100.Meanwhile, the buckle 142 in power brick 140 is in the draw-in groove being fastened on power brick mount pad 130, thereby reaches the object of self-contained battery bag 140 on electric tool 100.In the time that needs are changed power brick 140, press the buckle 142 of power brick 140 both sides, buckle 142 will be from draw-in groove out, thereby power brick 130 can be taken out from the power brick mount pad 130 of electric tool 100.Power brick 140 has also just disconnected with the electric connection of electric tool 100.

For power brick 140 more easily and is more stably arranged on power brick mount pad 130, the end of the power brick of this electric tool 100 is provided with locating dowel 144, is provided with the locating hole matching with locating dowel 144 in power brick mount pad 130.The cross section of the locating dowel 144 of power brick 140 ends can be triangle or quadrangle, the aperture of the locating hole of power brick mount pad 130 should be triangle or quadrangle relative to locating dowel 144.Like this, when power brick 140 is assembled on power brick mount pad 130, locating dowel 144 can match and be fixed with locating hole, thereby makes fixing more stable.Meanwhile, the guide effect of locating hole also makes the correct position that is installed to that power brick 140 can be more prone to.

This electric tool adopts at least two battery mounting bases to increase self can to install the quantity of power brick.This electric tool just can be installed at least two power brick simultaneously like this.Thereby the electric energy that this electric tool is had doubles, under same operating mode, the flying power of this electric tool doubles, thereby the frequency of changing battery is significantly reduced, and saves time.In addition, because this electric tool can use at least two power brick simultaneously, and these at least two power brick are connected in parallel, and the electric current that this electric tool can provide has also just at least increased by one times, the load that this electric tool can drive is like this just larger, and operating efficiency has also just improved.Therefore to have the battery number of times of replacing few for this electric tool, the advantage that operating efficiency is high.

The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
