Abstract
A screwdriver for precision equipment comprises a screwdriver handle, a screwdriver head and a screwdriver blade. The screwdriver body and the screwdriver blade are fixedly connected and are both made of electromagnetic materials. The screwdriver blade stretches into the screwdriver handle. A solenoid is wound around the part, stretching into the screwdriver handle, of the screwdriver body. A wire penetrates through the screwdriver body and the screwdriver blade, the screwdriver blade is provided with a light-emitting diode, the light-emitting diode is connected with the solenoid in parallel and controlled by a power source in the screwdriver handle and a switch, an auxiliary tube arranged outside the screwdriver body in a sleeving mode is further included, and one end of the auxiliary tube is close to the screwdriver blade. According to the technical scheme, illumination is achieved, and meanwhile it can be avoided that a light-emitting source is in a permanent magnetic environment; the service life of the screwdriver is prolonged. In addition, due to the fact that the auxiliary tube structure is adopted, a screw can be dismounted, mounted and collected more conveniently.
Description
Technical field
The present invention relates to a kind of screwdriver, particularly a kind of precision equipment screwdriver.
Background technology
In the unloading process of precision instrument or equipment, the problem being primarily present is: one is that the hole of some screw is relatively deep, bad visibility；Two is owing to screw is tiny, is difficult to alignment, easy deflection when dismantling and install；Three is easily to lose screw.
In the prior art, have been resolved about the lighting problem in the dismounting of precision equipment and installation process, but owing to screw is the most tiny, therefore had to utilize magnetic absorption screw, in magnetic field environment, but luminous source can be interfered with again for a long time, can impact effect.And other problems does not has real effective mode yet, or function singleness or according to solving technical problem.
Summary of the invention
It is desirable to provide novel precision equipment screwdriver, on the one hand solve luminous source problem in the environment of permanent magnetism, alignment screw when being on the other hand also convenient for dismounting and installed, collect the tiny screw backed out.
Concrete scheme is as follows:
A kind of precision equipment screwdriver, connects including handle of a knife, cutter hub and cutter head, described cutter hub and cutter head are fixing, and cutter hub and cutter head is made by electro permanent magnetic material, and cutter hub gos deep in handle of a knife, and the part that cutter hub gos deep in handle of a knife is wound with solenoid；Running through inside cutter hub and cutter head and have wire, cutter head position is provided with light emitting diode, and described diode is in parallel with solenoid and by the power supply in handle of a knife and on-off control, also includes an auxiliary tube being enclosed within outside cutter hub, and one end of described auxiliary tube is near cutter head position.
As the further improvement of such scheme, one end of the close cutter head of described auxiliary tube is provided with the movable Attraction block being made up of permanent-magnet materials, and auxiliary tube is provided with the opening taking out Attraction block in the outside of Attraction block position.
Use technical solutions according to the invention, while taking into account illumination, can avoid luminous source in the environment of permanent magnetism；Increase its service life.It addition, use auxiliary tube structure can also be more conducive to screw dismounting, install and collect.
Figure of description
Fig. 1 is the structural representation of precision equipment screwdriver of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further illustrated.
As it is shown in figure 1, screwdriver includes handle of a knife 1, cutter hub 2 and cutter head 3, cutter hub 2 gos deep in handle of a knife 3, and cutter hub 2 gos deep into the part in handle of a knife 1 and is wound with solenoid 4；There are wire cutter hub 2 and cutter head 3 internal running through, and cutter head 3 position is provided with light emitting diode 5, also includes an auxiliary tube being enclosed within outside cutter hub 6, and one end of auxiliary tube 6 is provided with Attraction block 7 near cutter head position.
Cutter hub 2 and cutter head 3 is fixing connects, and cutter hub 2 and cutter head 3 are made by electro permanent magnetic material, diode 5 is in parallel with solenoid and by the power supply in handle of a knife and on-off control, and Attraction block has permanent magnetism.
During dismounting precision equipment, first it is first turned on switch, connects corrugated tubing 4 and light emitting diode 5, go deep into and be directed at cutter head 3；Then keeping the most motionless state of auxiliary tube 6, rotate handle of a knife 1, during screwing out screw, auxiliary tube 6 all remains stationary as.After screw takes out, turning off the power switch, cutter head 3 loses magnetism, and screw is adsorbed block 7 and adsorbs without falling down；The correspondence position opening auxiliary tube 6 takes out Attraction block 7, puts screw well to be continuing with when installing.
When needing to install screw, being first placed on Attraction block 7 by screw and keep screw and the same direction of cutter head 3, being then turned on and off switch, auxiliary tube 6 is directed at installing hole, then rotates handle of a knife 1, is put in installing hole by screw.After installing, take out Attraction block 7.
Owing to Attraction block 7 is to install and of short duration use in unloading process, and cutter head 3 is also only just to have magnetic when installing and dismantle, and therefore the impact on diode 5 is the least.
Claims (2)
1. a precision equipment screwdriver, including handle of a knife, cutter hub and cutter head, it is characterised in that: described cutter hub and cutter head are fixed and are connected, and cutter hub and cutter head are made by electro permanent magnetic material, and cutter hub gos deep in handle of a knife, and the part that cutter hub gos deep in handle of a knife is wound with solenoid；Running through inside cutter hub and cutter head and have wire, cutter head position is provided with light emitting diode, and described diode is in parallel with solenoid and by the power supply in handle of a knife and on-off control, also includes an auxiliary tube being enclosed within outside cutter hub, and one end of described auxiliary tube is near cutter head position.
2. precision equipment screwdriver as claimed in claim 1, it is characterised in that: one end of the close cutter head of described auxiliary tube is provided with the movable Attraction block being made up of permanent-magnet materials, and auxiliary tube is provided with the opening taking out Attraction block in the outside of Attraction block position.
