The course of work of the present embodiment is: the pulling force that plug absorption armature overcomes extension spring makes it rotate, armature drives drive rod to rotate around the axis, stir seesaw button by the first bulbous protrusion 545 of the first pole, seesaw button drives Manual press seesaw to turn an angle by the second manual lever; When plug no longer adsorbs armature, extension spring band moving armature resets, armature and then drive drive rod rotate backward around the shaft to reset, now stir seesaw button by the second bulbous protrusion 546 of the second pole, and seesaw button drives Manual press seesaw homing by the first manual lever; Certainly, directly pressing Manual press seesaw also can be adopted to make its reciprocating rotation by force, seesaw button also can be driven back and forth to shake.
The advantage of the present embodiment can not only realize remote electric manipulation and automatically manipulate, and can also realize switching manipulation by hand.
(embodiment 3)
The present embodiment is substantially the same manner as Example 2, and difference is: in the present embodiment, the rear end of the first manual lever 613 of each Manual press seesaw is directly connected with the first pole 541 one of drive rod, no longer arranges the first bulbous protrusion 545; The rear end of the second manual lever 614 is directly connected with the second pole 542 one of drive rod, no longer arranges the second bulbous protrusion 546; Also namely each Manual press seesaw is connected with corresponding drive rod one, thus forms the structure of directly interlock.
The present embodiment has the following advantages: relative to embodiment 2, and the structure of the present embodiment simplifies more, and manufacturing cost is the end comparatively, and is connected due to rear end and the drive rod one of Manual press seesaw, thus makes the reliability of its work better.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to connotation of the present invention the apparent change of extending out or variation still belong to protection scope of the present invention.
