Wherein the power links to each other with control switch, and control switch is connected to the rotation regulation button via the wire on, the rotation regulation button meshes with the spiral pipe, and the spiral pipe can contact the slip with the coil relatively, and the coil twines on screw cutter arbor central africa permanent magnetism wand core, and the screw cutter arbor can coordinate with screwdrivers blade, and the coil is through wire and protection ohmic connection and finally be connected to control switch, gets back to the power, this screw cutter arbor comprises flux sleeve, non - magnetic media, non - permanent magnetism wand core simultaneously, puts the flux sleeve in non - permanent magnetism wand core periphery, and non - permanent magnetism wand core sets up the non - magnetic media of one deck, flux sleeve front end opening with the side of flux sleeve.
Description
Technical field
The utility model relates to a kind of electro-magnetism scroll driver of directional magnetic force, belongs to hand-operated tools.
Background technology
Normal screws cutter is exactly the screwdriver that a handle makes together, easy preparation, just can use as long as take out, but because screw has a variety of different length and rugosity, sometimes the screwdriver needing to prepare a lot of Zhi Butong with corresponding different model with the screw of kind, finding gets up to waste time and energy at all conveniently takies large quantity space simultaneously.
Most of screwdriver is in the market non-magnetic, being easy to screw is come off like this, making to occur during work that screw falls into the accident in machinery or installs loaded down with trivial details situation when installing small-sized screw or peace end position narrow space.
Segment screw knife-band is magnetic, but is all permanent magnetism driver bit, and when assembling some precision instruments, magnetic can produce interference to the precise part of instrument internal, magnetize instrument simultaneously, causes instrument to break down or hiding infringement, reduces instrument service life.
Common magnetic screw driver, magnetic field lines diverge, magnetic force distributes in three dimensions, and magnetic force is faint.
Summary of the invention
The purpose of this utility model is: the electro-magnetism scroll driver providing a kind of directional magnetic force, thus can overcome the defect of normal screws cutter in producing, living, and is more conducive to be applied to practice.
For achieving the above object; the technical solution adopted in the utility model is: a kind of electro-magnetism scroll driver of directional magnetic force, and device comprises power supply, gauge tap, wire, rotation adjusting knob, helix tube, coil, screwdriver rod, driver bit, protective resistance, flux sleeve, non-magnetic media, non-permanent magnetism bar core.Wherein power supply is connected with gauge tap; gauge tap is connected to via wire and rotates on adjusting knob; rotate adjusting knob to engage with helix tube; helix tube can contact slide relative to coil; coil winding is in screwdriver rod on non-permanent magnetism bar core; screwdriver rod can coordinate with driver bit, and coil to be connected with protective resistance by wire and to be finally connected to gauge tap, gets back to power supply.This screwdriver rod is by flux sleeve simultaneously, and non-magnetic media, non-permanent magnetism bar core form, and flux sleeve in non-permanent magnetism bar core outer race, the side of non-permanent magnetism bar core and flux sleeve arranges one deck non-magnetic media, flux sleeve front opening.
The utility model has following beneficial effect: (1), to the handling being arranged on instrument deep and shelter screw, has more superiority; (2) must the screw pulled down can not taken out safely by any aid; (3) magnetic force is concentrated, and can not magnetize the instrument component that it touches; (4) multiple cutter head is adapted to multiple situation; (5) structure is simple, with low cost, is applicable to large-scale application.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is screwdriver rod schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, an electro-magnetism scroll driver for directional magnetic force, device comprises power supply 1, gauge tap 2, wire 3, rotates adjusting knob 4, helix tube 5, coil 6, screwdriver rod 7, driver bit 8, protective resistance 9, flux sleeve 10, non-magnetic media 11, non-permanent magnetism bar core 12; It is characterized in that: power supply 1 connection control switch 2; gauge tap 2 is connected to via wire 3 and rotates on adjusting knob 4; rotate adjusting knob 4 to engage with helix tube 5; helix tube 5 can contact slide relative to coil 6; coil 6 is wrapped on the non-permanent magnetism bar core 12 in screwdriver rod 7; screwdriver rod 7 can coordinate with driver bit 8, and coil 6 to be connected with protective resistance 9 by wire 3 and to be finally connected to gauge tap 2, gets back to power supply 1.
As shown in Figure 2, screwdriver rod 7, comprises flux sleeve 10, non-magnetic media 11, non-permanent magnetism bar core 12.It is characterized in that: flux sleeve 10 in non-permanent magnetism bar core 12 outer race, non-permanent magnetism bar core 12 arranges one deck non-magnetic media 11 with the side of flux sleeve 10 and prevents leakage field excessive, flux sleeve 10 front opening.
Diagram gauge tap 2 is positioned at screwdriver shank depression, palm false touch when preventing stressed, but allows finger to carry out switching manipulation; Switch uses Push switch single finger manipulation preferably.
It is metal material that diagram rotates adjusting knob 4 inside, and On current arrives helix tube 5, and outside is rubber, plays the effect that resistance electricity is simultaneously anti-skidding.
Illustrative helicon pipe 5 is helical metal pipe, can control it and move up and down, reach the effect of the length of the coil 6 regulated in place in circuit, thus achieve the controllability of magnetic force size via rotation adjusting knob 4.
Diagram screwdriver rod 7 can coordinate multiple screws cutter head 8, thus improves the practicality of electro-magnetism scroll driver, decreases the use cost of screwdriver.
The effect of diagram flux sleeve 10 produces directional magnetic field, and the magnetic field of non-permanent magnetism bar core 12 itself is space three-dimensional distribution, and add that the magnetic field of the screwdriver rod 7 after flux sleeve 10 then concentrates on front end, other position does not exist magnetic field substantially.As shown in Figure 2, through test of many times, as obtaining maximum directional magnetic force effect, the area of flux sleeve 10 should be suitable with the area of non-permanent magnetism bar core 12, and like this, the magnetic field at permanent magnetism bar core 12 rear portion can be transmitted to front end losslessly.
The principle that the utility model utilizes hot-wire coil to produce magnetic field and magnetic force to change with coil number, control the magnetic of driver bit, because being provided with DC system, when pressing switch, namely screw is attracted on driver bit, though cutter head activity take office where to, screw also can not come off, especially to the handling being arranged on instrument deep and shelter screw, have more superiority, because the screw pulled down must can not take out safely by any aid by it, avoid falling into instrument internal and causing all harm.On the contrary, during trip switch, dump, screw comes off immediately on cutter head.And after power-off, remanent magnetism is very micro-on cutter head, the instrument component that it touches can not be magnetized.Regulatable magnetic force makes the application of screwdriver more flexible simultaneously, is applicable to multiple situation.The screwdriver that driver bit and handle separate, when dissimilar screw is installed, only driver bit need be changed just passable, not need to prepare and carry a large amount of screwdriver, can space be saved.
