The handle is connected with the bit, the electromagnetic coil for magnetizing the bit is wound at the front end of the handle, a rear cap is disposed at the rear end of the handle, a button cell is disposed in the handle, two button switches are arranged on the handle, a light emitting diode is disposed on the front end face of the handle, one button switch is connected serially together with the button cell and the electromagnetic coil to form a magnetizing circuit, and the other button is connected serially together with the button cell and the light emitting diode to form an illuminating circuit. A magnifying glass is mounted in the middle of the handle.

Description

A kind of multifunction electromagnetic screwdriver

Technical field:

The utility model relates to a kind of screwdriver, especially a kind of multifunction electromagnetic screwdriver that has illumination and magnifying glass.

Background technology:

At present, the electro-magnetism scroll driver of being sold on the market only has the function that turns screw, and when this electro-magnetism scroll driver turned screw under the more weak situation of light, the user did not see the groove of screw, can only find flight with feel, quite feels inconvenience.Sometimes in order to see flight or screw hole clearly, need to dispose flashlight in addition and throw light on, and when the configuration flashlight, need the another hand to hold, it is not too convenient to use.Also have when twisting some very little screws,, suffer from presbyopic user to some and make troubles because screw hole is too little.

The utility model content:

In order to overcome the deficiency of above-mentioned prior art, the utility model technical problem to be solved is to the existing existing deficiency of electro-magnetism scroll driver a kind of multifunction electromagnetic screwdriver to be provided.This electro-magnetism scroll driver disposes illuminating lamp, so that in the more weak environment of light, use.

Utility model technical problem to be solved also is to use the existing deficiency of electro-magnetism scroll driver and a kind of multifunction electromagnetic screwdriver is provided to suffering from presbyopic user.This electro-magnetism scroll driver disposes magnifying glass, uses conveniently to suffer from presbyopic user.

In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:

A kind of multifunction electromagnetic screwdriver comprises cutter head and the handle of a knife that is connected with said cutter head and is wrapped in and add the solenoid of magnetic on the said handle of a knife front end said cutter head that it is characterized in that: said handle of a knife is a hollow form, is provided with a bonnet in the rear end of said handle of a knife; In said handle of a knife, be placed with button cell and two press buttones on said handle of a knife; The end face of said handle of a knife front end is provided with light emitting diode; Press button is connected with said button cell, solenoid and is formed one and add magnetic circuit, another press button formation one lighting circuit of connecting with said button cell, light emitting diode.

At the middle part of said handle of a knife one magnifying glass is installed.

Owing to adopted as above technical scheme, the utility model gets electric and dead electricity through press button control solenoid, during use; Open press button, the solenoid energising produces magnetic field, adds magnetic to cutter head; When not using, can turn off press button, the solenoid dead electricity; The utility model just becomes a common screwdriver, adopts in such a way, can energy savings.

When in the more weak environment of light, using, can open the another one press button, light emitting diode provides illumination, no longer needs configuration flashlight in addition, and is easy to use.

Because the utility model disposes a magnifying glass, use in the time of can conveniently twisting the screw of minor diameter, also conveniently suffer from presbyopic user's use simultaneously.

Description of drawings:

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Fig. 1 is the utility model structure chart.

Fig. 2 is the electrical schematic diagram of the utility model.

1-cutter head among the figure, 2-handle of a knife, 3-light emitting diode, 4-solenoid, 5-magnifying glass, 6-press button, 7-press button, 8-bonnet.

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with specifically accompanying drawing and embodiment, further set forth the utility model.

Referring to Fig. 1 and Fig. 2, a kind of multifunction electromagnetic screwdriver shown in the figure comprises cutter head 1 and handle of a knife 2, and cutter head 1 is installed in the front end of handle of a knife 2, is wound with the solenoid 4 that adds magnetic to cutter head 1 at the front end of handle of a knife 2.

Handle of a knife 2 is a hollow form, is provided with a bonnet 8 in the rear end of handle of a knife 2; In handle of a knife 2, be placed with the button cell (not shown); And on handle of a knife 2 two

press buttones

6,7; The end face of handle of a knife 2 front ends is provided with light emitting diode 3; Press button 6 is connected with button cell E (referring to Fig. 2), solenoid 4 and is formed one and add magnetic circuit, press button 7 formation one lighting circuit of connecting with button cell E (referring to Fig. 2), light emitting diode 3.One magnifying glass 5 is installed at the middle part of handle of a knife 2.

Get electric and dead electricity through press button 6 control solenoids 4, during use, open press button 6; Solenoid 4 energisings produce magnetic field, add magnetic for cutter head 1, when not using; Can turn off press button 6, solenoid 4 dead electricity, the utility model just becomes a common screwdriver; Adopt in such a way, can energy savings.

When in the more weak environment of light, using, can open another one press button 7, light emitting diode 3 provides illumination, no longer needs configuration flashlight in addition, and is easy to use.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
