The specific embodiment

Now lifting preferred embodiment of the present utility model and conjunction with figs. is elaborated.

As shown in Figure 1 and Figure 2, being the electric tool of a preferred embodiment provided by the utility model, is an electric screw driver 1, and it includes:

One housing 10, housing 10 have one first one 11 and 1 second one 12.First one 11 inside forms an accommodation chamber 111, one ends to have an opening 112 and communicates with accommodation chamber 111.Second one 12 from first one 11 bottom is extended a predetermined length with one downwards greater than 90 ° angle, and its external diameter forms a joining base 121 beginning significantly to enlarge near the end, locates to form a junction surface 122 endways.Be formed with one first opening 123 and one second opening, 124, the first openings 123 for second one 12 and be positioned at position near first one 11,124 of second openings are positioned on the joining base 121.

One driven unit 20 comprises an electro-motor 21, a train of reduction gears 22 and a torque controlling device 23, connect in regular turn and be arranged in the accommodation chamber 111, and torque controlling device 23 stretches out in outside first one 11 from opening 112.In addition, torque controlling device 23 has an output shaft 231.

One tool holding device 30 has a pedestal 31 and a clamp assemblies 32.Pedestal 31 is fixedly arranged on first one 11, and it has one for the containing hole 311 that holds torque controlling device 23.Clamp assemblies 32 is incorporated on the ccontaining peritreme of pedestal 31, is used for clamping one bottle opener.Clamp assemblies 32 is connected with output shaft 231, can be subjected to the driving of output shaft 231 that the bottle opener of its clamping is rotated.

One battery component 40 includes a shell 41 and most rechargeable battery of being located in the shell 41 42.Battery component 40 can be incorporated into second one 12 junction surface 122 removably by shell 41, and can be electro-motor 21 electric power is provided.

One plate machine 50 is arranged in second one 12 first opening 123, is used for pushing to touch a switch that is located in the housing 10, the power supply of 40 pairs of electro-motors 21 of control battery component for the user.

One lamp group 60 is arranged in second one 12, and it has the fixed head 62 that five LED lamp bodies 61 and are used for fixing each lamp body 61.Each lamp body 61 is outside second one 12 second opening 124 is revealed in, and the light projecting direction of each lamp body 61 all throws on an instrument that is clamped on the clamping device 30, and comprises the preset range around the instrument.In addition, each lamp body 61 is by battery component 40 supply power supplys.

One first switch 70 is arranged on the fixed head 62, is used to control the power supply of 41 pairs of each lamp bodies 61 of battery component.

One electric weight testing circuit 80 is arranged in second one 12, is used to detect the dump energy of battery component 40.Testing circuit 80 electrically connects each lamp body 61, so that the result that will detect shows with the bright lamp digital display of each lamp body 61.

One second switch 90 is arranged on the fixed head 62, is used to control the startup of testing circuit 80.

One cover plate 100, its shape is identical with the opening shape of second opening 124, and offers the switch perforation 102 of five through holes 101 of corresponding each lamp body 61, corresponding first switch 70, a pressing plate 103 of corresponding second switch 90 on it.Cover plate 100 is combined on second opening 124, and each lamp body 61 and first switch 70 are passed from each through hole 101, switch perforation 102 respectively, and pressing plate 103 pressures are touched on second switch 90.

One switch sheath 104 is combined on the cover plate 100 and is set on first switch 70.

Adopt the electric screw driver of said structure, the user can hold second one 12 with holding, and pull plate machine 50 with forefinger, start clamp assemblies 32 rotations of electro-motor 21, to drive the bottle opener turn screw of clamp assemblies 32 clampings by train of reduction gears 22, torque controlling device 23 driven tool clamping devices 30.

As shown in Figure 3, when the user when the insufficient light part is used electric screw driver 1, can push first switch 70 and light each lamp body 61, utilize each lamp body 61 to be radiated on the bottle opener and the zone around the bottle opener of clamp assemblies 32 clampings, be convenient to user's work.
