Specific embodiment
With reference to Fig. 1～7 pair, the present invention elaborates.
As shown in figure 1, Magnet has the arctic 1 and 2 two, South Pole magnetic pole, there is magnetic field in Magnet, magnetic field sends magnetic strength by the arctic 1
Line, and return to the South Pole 2.Metal magnetic conducting material 3 is placed below Magnet, if by the north and south extreme direction of Magnet and metal magnetic conducting material
Expect that 3 is parallel and contact with each other so that the magnetic field of Magnet is conducted along metal magnetic conducting material 3, referred to as magnet short-cut path state, now Magnet and
The magnetic field of metal magnetic conducting material is closed in the middle of metal magnetic conducting material.
Embodiment 1
As shown in figs. 2 to 4, a kind of hardware ＆ tools of carrying magnetic adjusting means, including handle for tool 4, permanent magnet 6, armature
7th, metal rod 8, in handle for tool 4, the permanent magnet 6 is provided with rotary apparatuss to the permanent magnet 6, sets on the armature 7
There is concave surface, the permanent magnet 6 is arranged in concave surface, the lower section of the armature 7 connection metal rod 8.
The permanent magnet 6 is cylinder, and the magnetic pole of the permanent magnet is in the side of permanent magnet.
The permanent magnet 6 is provided with groove, and the rotary apparatuss are the magnetic regulator knob 5 being connected with permanent magnet 6, institute
State the one end of magnetic regulator knob 5 and be provided with projection, the groove is matched and closely coupled with projection, the magnetic regulator knob
5 other ends are provided with rotating hole.
A kind of using method of the hardware ＆ tools of carrying magnetic adjusting means, comprises the following steps：
A, face on the basis of the intersection of the South Pole of permanent magnet 6 and the arctic is set, rotation magnetic force actuator knob 5 make datum level and
Armature 7 is parallel, and hardware ＆ tools enters the state that magnetizes, and the magnetic that metal rod 8 is carried is most strong；
B, slow rotation magnetic force actuator knob 5, hardware ＆ tools entering part magnetizes state, the magnetic of metal rod 8 by
Decrescence weak, when datum level is vertical with armature 7, hardware ＆ tools enters magnet short-cut path state, and metal rod 8 is without being magnetic；
C, slow rotation magnetic force actuator knob 5, hardware ＆ tools is again introduced into the state that partly magnetizes, the magnetic of metal rod 8
Property gradually strengthen, when datum level is parallel with armature 7, hardware ＆ tools is entered and magnetized state, and the magnetic that metal rod 8 is carried is most
By force；
D, above-mentioned b, c operation of repetition, realize the regulation to hardware ＆ tools magnetic.
The magnetic of permanent magnet 6 is transmitted on metal rod 8 by armature 7, makes metal rod 8 have magnetic, can be adsorbed
Metal finding during instrument use, hardware ＆ tools is in the state that magnetizes.When rotation magnetic force actuator knob 5, permanent magnetism is made
When the arctic 1 or the South Pole 2 of ferrum are just to armature 7, the magnetic induction line distribution in magnetic field is as shown in Figure 5.The size of its magnetic force and permanent magnet 6
Magnetic be directly proportional, be directly proportional to the datum level of permanent magnet 6 and angle formed by armature horizontal direction.
During rotation magnetic force actuator knob 5, the magnetic pole of permanent magnet 6 is with the angle of cut of the horizontal direction of armature 7 from 90 °
Start, be gradually reduced, the magnetic line of force in magnetic field is gradually in partial short circuit state, and the magnetic field obtained on metal rod 8 gradually subtracts
It is weak.
After 90 ° of rotation magnetic force actuator knob, datum level and the horizontal direction parallel of armature 7 of permanent magnet 6, this
When magnetic field in magnetic induction line be closed in armature 7, in magnet short-cut path state, the magnetic induction line distribution in magnetic field is as shown in Figure 6.Now
The metal rod 8 of instrument does not have magnetic, and instrument is in demagnetized state, the magnetic susceptibility components and parts in equipment will not be produced bad
Affect.

Section, using simple, safe ready.
Preferably, upper surface of the center of gravity of the permanent magnet 6 higher than armature 7, it is to avoid make in magnetic regulator knob
When datum level is parallel with armature, the concave surface of armature 7 is contacted simultaneously with the south and north poles of permanent magnet 6, causes hardware ＆ tools to be in
Partial short circuit state, weakens the maximum magnetic of hardware ＆ tools.
Embodiment 2
The permanent magnet 6 of cylinder is substituted using spherical permanent magnet 6, when instrument is in magnetizes state, spherical permanent magnet
Magnetic pole --- the South Pole or the arctic are parallel with armature, when instrument is in magnet short-cut path state, the magnetic pole of spherical permanent magnet and rank
Ferrum is vertical.
Embodiment 3
As shown in fig. 7, in order to be easy to rotation to adjust magnetic force in use, but be unlikely to be easy to that mistake must be caused to grasp
Make, on one end that magnetic regulator knob 5 connects the external world an interior hexagonal rotating hole is provided with, adjust when rotation magnetic force is needed
Can be by hexagonal rotating hole in common die nut insertion during device knob 5, you can neatly rotation magnetic force actuator knob
5。
