It is connected into loop, controls switch and be installed on the handle of screwdriver body and be connected on the wire between coil and contact or spring；
The described switch that controls is resistance switch.
Further, described coil is coiled into by enamel-covered wire.
Further, described coil at least coiling two-layer.
Further, described mounting groove is the both sides of the handle being arranged in screwdriver body of two and specular.
Further, the described front end face controlling to switch the handle being installed on screwdriver body.
The beneficial effects of the utility model are: magnetic force of the present utility model linear controllable electromagnetic screwdriver, by using electricity
Magnetic induction principle, plus magnet exciting coil and DC source on screwdriver, using screwdriver metal knife bar as iron core, forms one
Individual small-sized electric magnet, carries out excitation, thus reaches to promote the effect of screwdriver magnetic force, use resistance switch screwdriver knife bar
Electric current in control coil, it is achieved coil current is from 0 to a range of linear regulation, and then makes the magnetic force of screwdriver linear
Controlled, according to size and the Weight control size of current of screw, Appropriate application electric energy, extend power supply service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model；Fig. 2 is the top view of Fig. 1, as shown in the figure: the magnetic force of the present embodiment
Linear controllable electromagnetic screwdriver, including screwdriver body, coil 1 and control switch 2；Described coil 1 is wound in screwdriver body
Knife bar 3；The handle 4 of screwdriver body is provided with the mounting groove 5 for installing aneroid battery；In mounting groove 5, corresponding aneroid battery sets
There are contact and spring；Contact and spring are connected to coil 1 for coil 1 and aneroid battery are connected into loop by wire, control
Switch 2 is installed on the handle 4 of screwdriver body and is connected on the wire between coil 1 and contact or spring；Described control is opened
Closing 2 is resistance switch；The knife bar 3 of screwdriver body is made up of permeability magnetic material, and the knife bar 3 of screwdriver body docks for multistage rod member
Demountable, including being fixed on the fixing bar of handle 4, the removable bar that disconnects being fixed on fixing bar front end, described line
Circle 1 is wound in any one and disconnects on bar, can change the entire length of knife bar 3 by installing the bar that disconnects of varying number, and
And the bar segment being wound with coil 1 can dismantle, it is simple to change and assemble, use motility good, practical, disconnect bar with fixing
Between bar and adjacent disconnecting is positioned by spline and spring catch clamping between bar, the end that two rod members are connected use plug and
The structure that slot matches, spline is located at outside plug and inside slot, spring catch is located at inside plug, slot inwall correspondence bullet
Spring pin is provided with draw-in groove, and spring catch includes radially sliding and is connected to the bayonet lock of plug and is supported in plug and card along bayonet lock glide direction
Spring between pin, it is ball head structure that bayonet lock protrudes one end of plug surface, and draw-in groove is that the ball head structure with bayonet lock matches
Rounded channels, inserts the connection that can realize rod member, easy accessibility after being directed at by the spline on plug and slot；By using electromagnetism
Principle of induction, using screwdriver metal knife bar 3 as iron core, forms a small-sized electric magnet, encourages screwdriver knife bar 3
Magnetic, thus reach to promote the effect of screwdriver magnetic force, uses the electric current in resistance switch control coil 1, it is achieved coil 1 electric current from
0 arrives a range of linear regulation, and then makes the magnetic force of screwdriver the most controlled, according to size and the Weight control of screw
Size of current, Appropriate application electric energy, extend power supply service life.
In the present embodiment, described coil 1 is coiled into by enamel-covered wire, described coil 1 at least coiling two-layer, Ampere theorem know,
The circular coil 1 of energising produces direction and passes perpendicularly through the magnetic field in the center of circle.It is coiled into spiral long loop 1, phase with a long wire
When in being in series by an a lot of circular coil 1.The magnetic field that each round conductor is set up at center is in the same direction, permissible
Enhancement effect, magnetic direction passes perpendicularly through helical coil 1 simultaneously, can approximate and regard straight line as in certain distance.We assume that
Coil 1 number of turn is N, and coil 1 electric current is I, and the pcrmeability of iron core is μ, and iron core radius is r.Magnetic induction nowMagnetic force produced by electric magnet can pass throughCalculate.Wherein S is the cross-sectional area S of iron core
=π r2, i.e. the final expression formula of the produced magnetic force of electric magnet can be written asVisible, certain at core material and size
In the case of, the magnetic force of electric magnet is current related with coil 1 number of turn and coil 1, and coil 1 number of turn is the most, passes through in coil 1
Electric current is the biggest, and the magnetic force of electric magnet is the biggest, uses the QZ-2/130L enamel-covered wire coiling of diameter 0.23mm in the present embodiment
1, winding length is 3cm, and around 2 layers, the number of turn is 235 circles.
In the present embodiment, described mounting groove 5 is the two of the handle 4 being arranged in screwdriver body of two and specular
Side, reasonable Arrangement mounting groove 5, it is possible to keep the structural strength of handle 4, it is ensured that serviceability.
