(5) specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the preferred embodiment of the electric tool of using when charger of the present utility model, be applicable to and drive a tool heads 100 rotations, this electric tool comprises a shell 1, a motor 2, several rechargeable batteries 3, a charging circuit 4, a driver element 5, a power supply unit 6, a switching switch 7, a bulb 8, an indicator lamp 9, and a boost-up circuit 10.
As shown in Figure 3, Figure 4, this shell 1 is the hollow housing of reservation shape, and has and one define the bottom 12 of an accommodation space 11, be formed at a breach 14 of a leading flank 13 respectively, and a supply hub 15, and this accommodation space 11 has an opening 111.
This motor 2 is to be placed in this shell 1 inside.
This power supply unit 6 has one and is removably the joint 61 that electrically connects with this supply hub 15, and one be applicable to the plug 62 that electrically connects with an external power source (figure does not show), to provide power supply to this motor 2 and this rechargeable battery 3.
Bottom 12 openings 111 that this rechargeable battery 3 is removably by this shell 1 are installed in this accommodation space 11, and in this embodiment, this rechargeable battery 3 is made up of four No. three batteries.And the battery that this rechargeable battery 3 can be used as electric tool uses, and (for example: walkman, digital camera, remote controller, phone also can independently be used as general electrical appliance ... or the like) but the cradle used of rechargeable battery recharge.
In addition, the general battery of the also replaceable one-tenth of this rechargeable battery 3, when general battery was installed on this accommodation space 11, the battery of only being used as this electric tool used, and does not have charge function.
As shown in Figure 1, this charging circuit 4 is to be placed in this shell 1 inside, and electrically connect with this rechargeable battery 3, when this rechargeable battery 3 is installed on this accommodation space 11, and when this power supply unit 6 is connected to this supply hub 15, except utilizing motor 2 runnings of power supply unit 6 external power supplys supply electric tool, also can pass through 4 pairs of these rechargeable battery 3 synchronous charging of this charging circuit.
As Fig. 1, shown in Figure 3, this driver element 5 has one and is applicable to the actuator 51 that is connected with this tool heads 100 and can be driven rotation by motor 2, and a forward-reverse switch 52 that is embedded in breach 14 inside of this shell 1.
This indicator lamp 9 electrically connects with this rechargeable battery 3, and when this rechargeable battery 3 is installed on this accommodation space 11, and power supply unit 6 is when being connected to this supply hub 15, can be via 3 chargings of 4 pairs of these rechargeable batteries of this charging circuit, and this indicator lamp 8 is lighted.
As Fig. 2, shown in Figure 3, this change-over switch 7 is sides 16 that are formed at this shell 1, and electrically connects with this rechargeable battery 3.
