To, drive rod 52 one end (such as, it is illustrated that lower end) can stretch into accommodating chamber 50, and one end of drive rod 52 has
Hook portion 521, drive rod 52 the other end (i.e., it is illustrated that upper end) can be connected with transmission component 4；Operating member 53 is movably
It is located in accommodating chamber 50, operating member 53 can have limiting plate 531, as shown in fig. 6, between limiting plate 531 has in the up-down direction
It separates and V-shaped groove 532 that both ends are respectively communicated with, operating member 53 is equipped with the limit shaft 533 extended downwardly, is covered on limit shaft 533
Equipped with compression spring 57, the both ends of compression spring 57 are only butted on operating member 53 and shell 51 respectively；The lower end difference of two hooks 54 is pivotable
Ground is located on operating member 53, and the upper end of two hook portions 521 can be opened and closed only to be butted on shell 51, two hook portions 521
Lower end is equipped with for driving the torsional spring 55 of hook portion 521 away from each other；Guide rod 56 can be located in accommodating chamber 50, guide rod 56
Lower end be pivotly connected with shell 51, the upper end of guide rod 56 is movably arranged in V-shaped groove 532.
Wherein, in demagnetization position, as shown in Fig. 2, 52 pushing action portion 53 of drive rod moves down, so that two hooks 54
It is neighbouring pivotally and hooking is in hook portion 521, also, the upper end of guide rod 56 can be moved to a V-arrangement being located above
In slot 532, in magnetisation position, as shown in Figure 4 and Figure 6, in magnetisation position, the upper end of guide rod 56 is moved to underlying one
In a V-shaped groove 532, under the action of compression spring 57, operating member 53 moves up so that two hooks 54 are remote in opening 501 respectively
From moving each other and discharge hook portion 521.
The operation principle of shutter (that is, actuator 5) is described below in detail：
53, two hooks 54 of operating member and guide rod 56 in accommodating chamber 50 constitute action subject, action master
Body can move up and down one end distance, and the openable and closable hook 54 of two be arranged on operating member 53 is mounted on equipped with torsional spring 55
On pivotal axis, open that there are two the openings 501 identical with 54 width of hook on shell 51, when no external force makes action subject move down,
Two hooks 54 are in 501 states of opening under the action of torsional spring 55, at this point, hook 54 does not influence moving up and down for drive rod 52.
On the operating member 53 of action subject, about two superpositions are set, the V-shaped groove 532 that both sides are linked up, the V-shaped groove 532 being located above
Bottom is provided with upper end mouth hanging, and 532 lower part of underlying V-shaped groove is equipped with lower end mouth hanging, and compression spring is installed in the lower part of operating member 53
57 and guide rod 56, compression spring 57 be set on limit shaft 533, radially extending along shell can be arranged in the middle part of guide rod 56
The lower end of spring, guide rod 56 is pivotly connected with shell 51, and the upper end of guide rod 56 can be flexibly along two V-shaped grooves 532
Sliding.
When drive rod 52 moves down pushing action portion 53, entire action subject overcomes the elastic force of compression spring 57 to moving down
Dynamic, two hooks 54 being located on operating member 53 overcome the tension of torsional spring 55 to be gradually closed, and the upper end of guide rod 56 is in V-shaped groove
Gradual upward sliding in 532, when sliding into the upper end mouth hanging of V-shaped groove 532 of top, drive rod 52 and operating member 53
It moves down and is restricted, operating member 53 is directed to the limit of bar 56, and the hook portion 521 of drive rod 52 is caught on by two hooks 54, reaches
The purpose of shutter hooking.
If at this point, drive rod 52 moves down pushing action portion 53 again, the upper end of guide rod 56 can be first under V-shaped groove 532
It moves, at the lower end mouth hanging for the V-shaped groove 532 that can finally rest on lower section and is limited, simultaneously, operating member 53 is in compression spring 57
Tension force effect under move up rapidly, two hook 54 under the action of torsional spring 55 opening 501 in away from each other pivot in opening
501 states discharge the hook portion 521 of drive rod 52, to achieve the purpose that drive rod 52 is released.
It should be noted that when the lifting height of drive rod 52 can expire magnetic state with magnetic suction disc 100 transmission component 4 height
Degree is consistent, real to achieve the purpose that drive rod 52 drives the second magnetic pole 2 to be pivoted relative to the first magnetic pole 1 by transmission component 4
Existing switching of the magnetic suction disc 100 between magnetisation state and erasing state.
Optionally, as shown in Fig. 2, Fig. 4 and Fig. 6, the top of shell 51 is equipped with outer silk snap ring 511, outer silk snap ring 511 with
Shell 51 is threadedly coupled, so as to be adjusted by rotating position of the outer 511 external snap rings of silk snap ring 511 on shell 51
It is whole, limit the extreme higher position of drive rod 52.
In some embodiments, as shown in Fig. 1, Fig. 3 and Fig. 5, magnetic suction disc 100 can also include：Lock assembly 7, lock
