Abstract
The invention provides a magnetically controllable screwdriver which comprises a handle (1) and a screwdriver rod (2), wherein the handle (1) is internally provided with a power supply (3) and a switch (4); the screwdriver rod (2) is provided with a coil (5) which is connected with the power supply (3) and the switch (4) so as to form a closed loop; and the coil (5) is electrified, so that the screwdriver generates magnetism or gets rid of the original magnetism of the screwdriver. Compared with the prior art, the screwdriver has the following advantages: when the same screwdriver needs magnetic force, the switch can be converted, so that the screwdriver has magnetic force; when the same screwdriver does not need magnetic force, the switch is converted and the magnetic force disappears; and although the screwdriver head automatically generates the magnetic force due to long use, corrective demagnetization can be also carried out, thus achieving free control of the magnetic force of the screwdriver head.
Description
Technical field
The present invention relates to daily life tools, relate in particular to the controlled screwdriver of a kind of magnetic.
Background technology
Conventional screwdriver is made up of handle and batch bar, and handle and batch bar are integral non-dismountable, and the screwdriver bit of batch bar is yi word pattern or cross, or the screwdriver bit exchangeable.A kind of screwdriver is disclosed as utility model patent ZL 200520042647.7, it is made up of combination handle, fastening clips, double end bar, double end bar one end of screwdriver is yi word pattern, the other end is the cross blossom type, the middle part of screwdriver is provided with a fastening clips, it is made up of latch segment, spring, can fastening and pinning double end bar.The combination handle that the rear end of screwdriver is made up of inner sleeve, outer tube, locating piece, plastic cement handle, locating piece is arranged in the plastic cement handle, has the cross notch, is used for the location of double end bar.The advantage of this utility model is: one is dual-purpose screwdriver.The tune of the double end bar by screwdriver is used, and makes it both can make slot type screwdriver, can make Philip's type screwdriver again.
When using screwdriver, lose in order to prevent screw, need magnetic screwdriver, when tightening screw or taking off screw, screw is inhaled at the top of lead screw, handled easily, therefore, be everlasting in the prior art and apply magnetic material on the screwdriver bit or use the magnet magnetization screwdriver bit, reaching the purpose of preserving screwdriver magnetic, but this screwdriver, and magnetic is uncontrollable, often adsorb to walk to have aimed the place in use and wait for situation about tightening the screw, allow use become inconvenient.
Therefore, the someone utilizes the controlled character of the magnetic of electromagnet, has invented the controlled screwdriver of magnetic, and utility model patent ZL200920263652.9 discloses the controlled screwdriver of magnetic, belongs to daily instrument.This its essence is to be provided with insulated coil on the lead screw of screwdriver, and described insulated coil and switch and dc source are connected in series and constitute the closed-loop path.This utility model utilization energising insulated coil makes screwdriver have magnetic, and realizes the controlled of magnetic by the break-make of switch control electric current.
But, the screwdriver that this magnetic is controlled, very limited to the control of magnetic, in fact, the not magnetic screwdriver of routine is after often using, and its screwdriver bit also can produce magnetic, even magnetic is preserved in magnetization.
Summary of the invention
Purpose of the present invention can freely be controlled magnetic force in order to provide a kind of, also can be corrected the controlled screwdriver of magnetic that demagnetization is handled.
In order to achieve the above object, the present invention has adopted following technical scheme: the controlled screwdriver of a kind of magnetic, comprise handle 1 and batch bar 2, it is characterized in that, be provided with power supply 3 and switch 4 in the described handle 1, described batch of bar 2 is provided with coil 5, and this coil 5 connects and composes the closed-loop path with power supply 3 and switch 4, coil 5 energisings make screwdriver generation magnetic or make the original magnetic demagnetization of screwdriver.
Described switch 4 be the utmost point to change-over switch module, be provided with switch toggle and three gears: A shelves, B shelves and C shelves, when switch toggle contact A shelves and C shelves, the direction that electric current flows through coil 5 is opposite, during switch toggle contact B shelves, coil 5 outages.
The other indicator lamp A that is provided with of described A shelves, described switch toggle contact A shelves, coil 5 energisings produce magnetic field, and indicator lamp A lights, and batch bar 2 in the coil 5 produces magnetic.
Described switch toggle contact B shelves, coil 5 outages, batch bar 2 magnetic in the coil 5 disappear.
The other indicator lamp C that is provided with of described C shelves, described switch toggle contact C shelves, coil 5 energisings produce magnetic field, and indicator lamp C lights, and batch bar 2 in the coil 5 produces the magnetic opposite with the A shelves.
Described switch toggle is arranged on handle 1 bottom.
Described power supply 3 is a battery, and this battery is arranged in the handle, and the negative pole butt utmost point of battery is to change-over switch module 4, and anodal butt is criticized bar 2 one ends, and perhaps the anodal butt utmost point of battery is to change-over switch module 4, and the negative pole butt is criticized bar 2 one ends.
Described coil 5 is the adjustable coil of the number of turns, the coil 5 outer insulated coil sheaths 6 that are with.
Described batch of bar 2 front ends stretch out outside the insulated coil sheath 6.
Described batch of bar 2 front end are the screwdriver of replaceable screwdriver bit or the fixing screwdriver of screwdriver bit.
Compared with prior art, the present invention utilizes the controlled character of the magnetic of electromagnet, sheathed coil on batch bar, coil electricity or outage make screwdriver bit produce magnetic or carrying magnetic not, and can be according to sense of current difference on the coil, produce the opposite magnetic field of magnetic, make screwdriver produce magnetic, or sense of current make screwdriver produce the magnetic opposite with its original magnetic in the coil by changing, and carries out demagnetization.Therefore, the present invention is same as screwdriver, when needs magnetic force helped, just the energy change-over switch made it have magnetic force, when not needing magnetic force, change-over switch, magnetic force just can disappear, even the screwdriver bit head is because of the self-produced magnetisation power of permanent use, also can correct demagnetization and handle, accomplish freely controlling screwdriver bit magnetic force.
