Description
Technical field
The utility model relates to a kind of electric screw driver, especially a kind of electric screw driver.
Background technology
The utility model patent that existing a kind of application number is CN201220395339.2, this utility model discloses a kind of electric screw driver, by handle, connecting rod and cutter head form, the connecting rod front end is established the polygon groove, cutter head reliably is connected with connecting rod by the polygon groove, establish supported chamber in described handle, excitation chamber and power house, described supported chamber is positioned at the handle front end, inside establish at least one bearing, described excitation chamber is positioned at the handle middle part, at least two permanent magnets of corresponding setting, described power house is positioned at the handle afterbody, internal battery and outer wall arrange civil power connector and switch, described connecting rod end is indoor to excitation through supported chamber, and end is established induction coil.The utility model is simple in structure, operating efficiency is relatively high, not limited by place, applied widely, but this utility model does not arrange decelerator, be equivalent to directly connect motor, can make like this moment of torsion of output less, can not rotate some screws, this utility model is not provided with some screwdriver heads commonly used simultaneously, make use single, external charger, can make charging be restricted simultaneously.
The utility model content
In order to overcome the deficiency of above-mentioned existing electric screw driver, the purpose of this utility model is to provide a kind of electric screw driver, and it adopts and is provided with battery, control circuit, motor and reduction box in enclosure interior.
In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of electric screw driver is characterized in that: it consists of housing, three-jaw fixture block, thread bush, top cover, battery, motor, reduction box; Described housing is cylindric, and upper end is provided with top cover, and lower end is provided with three-jaw fixture block and thread bush, and front end is provided with switch, and rear end is provided with plug, and inside is provided with that a word rises, cross rises, battery, control circuit, motor and reduction box.
The beneficial effects of the utility model are: it can either be used for facilitating rotating screw, again can Reusability, be applicable to rotating the screw of Multiple Type, and simple in structure, easy to use, widely applicable.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model rearview
The A-A that Fig. 3 is Fig. 2 is to cutaway view
In figure, 1-top cover, 2-switch, 3-three-jaw fixture block, 4-plug, 5-housing, 6-thread bush, 7-mono-word rise, 8-battery, 9-motor, 10-cross rise, 11-control circuit, 12-reduction box.
The specific embodiment
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, a kind of electric screw driver is characterized in that: it consists of housing, three-jaw fixture block, thread bush, top cover, battery, motor, reduction box; Described housing is cylindric, and upper end is provided with top cover, and lower end is provided with three-jaw fixture block and thread bush, and front end is provided with switch, and rear end is provided with plug, and inside is provided with that a word rises, cross rises, battery, control circuit, motor and reduction box.
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 3, the upper surface of described housing is provided with groove, and groove rises with cross and rises for a word of placing standby different model, for being convenient for people to use; Described top cover is cylindric, and outer surface is provided with non-slipping block, by screw thread, with the upper end of housing, is connected, and for preventing that the standby word from rising with cross, plays loss; A described word plays the tail end risen with cross and is made as six prisms, facilitates the three-jaw fixture block to block; Described plug is connected with control circuit by wire, and upper end is connected with shell by spring rotary shaft, for facilitating external power supply; Described switch is connected with control circuit by wire, and can upper and lowerly slide, for the forward of controlling motor, reverse or close.
In the 3rd embodiment shown in Fig. 1, Fig. 3, the inside of described control circuit is provided with transforming circuit, rectification circuit, mu balanced circuit, charge protector and control positive and negative rotation of motor circuit, for charging a battery after external power supply decompression, rectification and voltage stabilizing, simultaneously by the rotation of the residing Position Control motor of switch; Described battery is connected with control circuit by wire, for to motor, providing electric energy; The upper end of described reduction box is connected with the rotating shaft of motor, and lower end is connected with the upper end of three-jaw fixture block, for increasing the moment of torsion of three-jaw fixture block.
In the 4th embodiment shown in Fig. 1, Fig. 3, described thread bush is cylindric, is provided with internal thread; The outer surface of described three-jaw fixture block is provided with screw thread, lower surface is provided with groove, with thread bush, support the use, when thread bush rotates, the groove of lower surface will diminish, for tightening the upper end that a word rises or cross rises, when thread bush upwards rotates, the groove of lower surface will become greatly, for unclamping the upper end that a word rises or cross rises.
While using the utility model, at first will open plug, accumulators is full of electricity, then takes out that a word that needs to use rises or cross rises, and is enclosed within the groove of lower end of three-jaw fixture block, then screws thread bush, just can open the switch use, simple in structure, easy to use.
