4. according to the energy-saving mechanism described in any one in claim 1-3, it is characterized in that: the interlock of described return unit (1415) and described moving iron core (1104) arranges and be corresponding with described dropout end (1414) interval, described return unit (1415) moves and promotes described dropout end (1414) and get back to described return position at described dropout end (1414) the backward described dropout end (1414) that is triggered.
5. according to the energy-saving mechanism described in any one in claim 1-3, it is characterized in that: portion (1412b) is triggered described in described return unit (1415) is described locking piece (1412), the described portion that is triggered (1412b), after described dropout end (1414) triggers, promotes described dropout end (1414) and gets back to described return position under the described partial pressure of described bias piece (1403).
6. energy-saving mechanism according to claim 4, is characterized in that: described trip unit is release.
7. energy-saving mechanism according to claim 6, it is characterized in that: described locking piece (1412) is set to two, locking piece described in two (1412) is arranged symmetrically in the both sides of described moving iron core (1104), between locking piece described in two (1412), by connection bracket (1418), connects.
8. energy-saving mechanism according to claim 7, is characterized in that: described bias piece (1403) is for fixing one end, and the other end is connected to the extension spring on described locking piece (1412).
9. energy-saving mechanism according to claim 8, it is characterized in that: also comprise the fixed support (1419) being arranged on described electromagnetic mechanism, described fixed support (1419) is upper is provided with pivot (1419a) with described locking piece (1412) corresponding position, and described locking piece (1412) forms the pivoting hole (1412d) coordinating with described pivot (1419a).
10. energy-saving mechanism according to claim 9, is characterized in that: described electromagnetic mechanism also comprises reaction spring (1420), and described reaction spring (1420) imposes on described moving iron core (1104) one reaction forces; Described moving iron core (1104) is locked in described initial position by described reaction force before described coil (1103) energising, in described coil (1103) moment of switching on, overcomes described reaction force and moves to described attracted position by described initial position.
