Abstract
The utility model relates to a rapidly chargeable electric screwdriver, which comprises a casing (1). The front end of the casing (1) is provided with a bit clamp (2) capable of detachably holding a screwdriver bit; a motor (3) is arranged in the casing (1); and the motor (3) is connected with the bit clamp (2) by the aid of a transmission structure so as to drive the bit clamp (2) to rotate. The rapidly chargeable electric screwdriver is characterized in that a capacitor (4) for supplying electric power to the motor (3) is arranged in the casing (1). The electric screwdriver adopts the capacitor to replace a storage battery in an existing electric screwdriver, and the capacitor is rapid in charging according to the charging principle of the capacitor, so that the electric screwdriver adopting the capacitor as a power supply can be fully charged only in a few minutes, the purpose of charging and using is achieved, and the electric screwdriver is quite convenient to use. In addition, the capacitor without containing heavy metal and other harmful substances is less in environmental pollution.
Description
Technical field
The utility model relates to a kind of quick charged electric screw driver.
Background technology
Existing charged electric screwdriver comprises the housing with handle, the front end of housing is provided with the Tool bil holding device that is used for keeping removably driver bit, be provided with motor in the body portion of housing, motor links to each other with Tool bil holding device to drive the Tool bil holding device rotation by drive mechanism, and the shank of housing is equipped with the energy charge power supply that power is provided to motor.
The charged electric screwdriver adopts lithium battery or nickel-cadmium cell as power supply at present, when battery consumption causes torque to be the decline of screwdriver fastening ability, must charge to battery by external power source, with resetting torque.As a patent No. is the Chinese utility model patent " direct current drive screwdriver " of ZL01271639.1 (notification number is CN2508901Y), reaching an application number is the Chinese invention patent " charged electric screwdriver " of ZL201010525872.1 (publication number is CN101983844AY), and they have all disclosed a kind of like this charged electric screwdriver.
Because defectives such as existing battery heaviness, charging interval length, general charging once needs half an hour at least, under the situation that runs into urgent need, make troubles for our work, existing storage battery exists also that to discharge and recharge the life-span short and because of using heavy metal and harmful substance to problems such as environment are unfavorable in addition.
In sum, existing charged electric screwdriver also can be further improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of small portable, quick charged electric screw driver at above-mentioned prior art present situation, and this screwdriver also has long, free from environmental pollution advantage of charging life-span.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of quick charged electric screw driver, comprise housing, the front end of housing is provided with the Tool bil holding device that is used for keeping removably driver bit, be provided with motor in the housing, motor links to each other with Tool bil holding device in order to drive the Tool bil holding device rotation by drive mechanism, it is characterized in that: be provided with the electric capacity that electric power is provided to motor in the described housing.
Above-mentioned electric capacity has two, and they are cascaded.
The shank that above-mentioned housing has horizontally disposed body portion and vertically is provided with, Tool bil holding device is positioned at the front end of body portion, and motor and drive mechanism are positioned at body portion, and described electric capacity then is positioned at shank.Housing has shank to be convenient to the operator and to hold and take, and in addition electric capacity is located in the shank, makes this electric screw driver lateral length be unlikely to oversize, and integral layout is more reasonable.
Compared with prior art, advantage of the present utility model is: this electric screw driver adopts electric capacity to replace the battery that has now in the electric screw driver, according to the charging principle of electric capacity as can be known, electric capacity has the fast characteristics of charging, therefore adopt electric capacity only to need just electricity can be full of several seconds as the electric screw driver of power supply, realize promptly filling the i.e. purpose of usefulness, it is quite convenient to use, electric capacity does not contain heavy metal and other harmful substance in addition, and environmental pollution is few.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the user mode reference diagram of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, be a preferred embodiment of the present utility model.
A kind of quick charged electric screw driver, comprise housing 1, the front end of housing 1 is provided with the Tool bil holding device 2 that is used for keeping removably driver bit, be provided with motor 3 in the housing 1, motor 3 links to each other with Tool bil holding device 2 in order to drive Tool bil holding device 2 rotations by drive mechanism, be provided with the electric capacity 4 that electric power is provided to motor 3 in the housing 1, electric capacity 4 has two, and they are cascaded.
According to the charging principle of electric capacity as can be known, electric capacity has the fast characteristics of charging, therefore adopts electric capacity only to need just electricity can be full of several seconds as the electric screw driver of power supply, realizes promptly filling the i.e. purpose of usefulness, it is quite convenient to use, during charging, as shown in Figure 2, only need be plugged in electric screw driver on the cradle 6 and get final product, electric capacity can not charge for a long time in addition, the circuit pack of cradle 6 needs charging interval control for this reason, surpasses setting-up time as the charging interval and just cuts off the power supply automatically, no longer charges.
