Abstract
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.Use technical scheme described in the utility model, 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.
Description
Technical field
This utility model 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
It is owing to screw is the most tiny, therefore has to utilize magnetic absorption screw, but can interfere with again in magnetic field environment for a long time
Luminous source, can impact effect.And other problems does not has real effective mode yet, or function singleness or according to nothing
Method solves technical problem.
Summary of the invention
This utility model aims to provide novel precision equipment screwdriver, on the one hand solves luminous source in permanent magnetism
Problem in environment, 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
Body 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；Cutter
Running through inside body 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 handle of a knife
Interior power supply and on-off control, also include 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 by permanent-magnet materials system
The movable Attraction block become, auxiliary tube is provided with the opening taking out Attraction block in the outside of Attraction block position.
Use technical scheme described in the utility model, while taking into account illumination, luminous source can be avoided at permanent magnetic
In the environment of property；Increase its service life.It addition, use auxiliary tube structure can also be more conducive to screw dismounting, install and collect.
Accompanying drawing explanation
Fig. 1 is the structural representation of precision equipment screwdriver described in the utility model.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is further described.
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 handle of a knife
Part in 1 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
Including an auxiliary tube being enclosed within outside cutter hub 6, one end of auxiliary tube 6 is provided with Attraction block 7 near cutter head position.
Cutter hub 2 and cutter head 3 are fixed and are connected, and cutter hub 2 and cutter head 3 are made by electro permanent magnetic material, diode 5 and solenoid
In parallel and by the power supply in handle of a knife and on-off control, 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
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 keeps not
Dynamic.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；Open auxiliary
The correspondence position helping pipe 6 takes out Attraction block 7, puts screw well to be continuing with when installing.
When needing to install screw, first screw is placed on Attraction block 7 and keeps screw and the same direction of cutter head 3, then
Power-on switchs, and 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
Go out Attraction block 7.
Owing to Attraction block 7 is to install and of short duration use in unloading process, and cutter head 3 be also only install and during dismounting
Having magnetic, 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
Connecting, and cutter hub and cutter head are made by electro permanent magnetic material, 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 including an auxiliary tube being enclosed within outside cutter hub, one end of described auxiliary tube is close
Cutter head position.
