Abstract
The utility model discloses an electric bit head switching device. The electric bit head switching device comprises a shell body and two gear devices, wherein the two gear devices are arranged at two ends of the interior of the shell body respectively, each gear device comprises a gear sleeved on a rotary shaft, the two gears are connected in a synchronous rotating mode through a chain, the axis of one rotary shaft is provided with a bit head inserting hole, and the axis of the other rotary shaft is provided with a worm inserting hole. According to the electric bit head switching device, the bit body and the bit head of an electric bit can work independently, operation space is greatly reduced, a bolt located in a corner gap or in a narrow space can be screwed or unscrewed through the bit head, and therefore the electric bit head switching device is quite convenient to use and practical.
Description
Technical field
The utility model relates to the electric screwdriver technology, relates in particular to a kind of electric screwdriver head switching device.
Background technology
Electric screwdriver also is electric screw driver or electric screw driver (electric screwdriver), is be used to tightening and unscrew the electric tool that screw is used.This electric tool is equipped with the mechanism of adjusting and torque limiting, is mainly used in assembly line, is one of instrument of most of manufacturing enterprise indispensability.Electric screwdriver is desirable efficient fast assembly of tools, is widely used in industries such as aviation, automobile, machine, electrical equipment, and for raising labour productivity, alleviating labor strength has significant effect.The electric screwdriver of prior art mainly is made up of three parts: 1), provide the power source of power source; 2) energy conversion mechanism; 3) screwdriver bit of locked screw.Wherein, screwdriver bit is by worm screw and described power source and energy conversion mechanism, and integral body forms linear structure.
Yet the inventor finds that in implementing process of the present utility model because the overall structure of electric screwdriver is bigger, it is longer particularly to criticize body, in use, must stop enough operating spaces to electric screwdriver.Thereby the screw that some are in place, slit, corner or small space owing to there is not the bigger electric screwdriver of enough spaces receiving volume, just can't use the electric screwdriver operation.
The utility model content
Technical problem to be solved in the utility model is: a kind of electric screwdriver head switching device is provided, this device can reduce the screw upper space of electric screwdriver action need greatly, make the screw that is in place, slit, corner or the small space also can adopt screwdriver bit to screw or loosening operation, very convenient and practical.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electric screwdriver head switching device, this device includes housing, is divided into two geared systems at these enclosure interior two ends, each geared system includes a gear that is sheathed in the rotating shaft, be rotationally connected synchronously by chain between two gears, and one of them rotating shaft core is provided with the screwdriver bit jack, another rotating shaft core is provided with the worm screw jack.
Preferably, also be provided with screw hole on the described housing.
The beneficial effects of the utility model are:
Embodiment of the present utility model drives the gear that is arranged with screwdriver bit jack and worm screw jack of being located at the housing two ends by chain and rotating shaft and is rotationally connected synchronously, thereby batch body of electric screwdriver and the physical separation of screwdriver bit have been realized, reduced the screw upper space of electric screwdriver action need greatly, make the screw that is in place, slit, corner or the small space also can adopt screwdriver bit to screw or loosening operation, very convenient and practical.Not only can be applicable to industrial circle, also be fit to very much family and use.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of an embodiment of electric screwdriver head switching device of the present utility model.
The specific embodiment
Describe an embodiment of the electric screwdriver head that the utility model provides in detail below with reference to Fig. 1; As shown in the figure, present embodiment mainly includes housing 1, is divided into two geared systems 2 at these housing 1 inner two ends, each geared system 2 includes a gear 22 that is sheathed in the rotating shaft 21, be rotationally connected synchronously by chain 3 between two gears 22, and one of them rotating shaft 21 axle center is provided with screwdriver bit jack 4, another rotating shaft 21 axle center are provided with worm screw jack 5.
During specific implementation, also can be provided with screw hole 11 on the housing 1.
Describe the operation principle of present embodiment below in detail.
During use, unload the screwdriver bit of electric screwdriver, and after being inserted into the screwdriver bit jack 5 of present embodiment, worm screw being inserted the worm screw jack 4 of present embodiment, present embodiment can be fixed on the screwdriver bit junction of electric screwdriver.Again screwdriver bit is stretched in the screw that needs operation, open electric screwdriver work, drive two gears 22 by worm screw and chain 3 and rotate synchronously, thereby drive the screwdriver bit rotation work.Used after the electric screwdriver head switching device of present embodiment, the screwdriver bit of electric screwdriver and batch body are realized physical separation by this device, thereby reduced the screw upper space of electric screwdriver action need greatly, make the screw that is in place, slit, corner or the small space also can adopt screwdriver bit to screw or loosening operation, very convenient and practical.Not only can be applicable to industrial circle, also be fit to very much family and use.
The above is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
