The first operating mechanism 1 shown in Fig. 1 and Fig. 2 and second operation machine structure 7 are in same operating state, namely the first operating mechanism 1 is in gate-dividing state and is prohibited closing operation (namely its first dropout semiaxis 101 is in latched position), and second operation machine structure 7 is in closing operation state (namely it is in and allows closing operation state), its second dropout semiaxis 701 is in the unlocked position.See Fig. 1 and Fig. 3, the first activation lever 33 that the closing operation of second operation machine structure 7 makes the second cantilever 7031 in its second rotating shaft 703 promote the first lever assembly 3 moves, mobile promotion first rotating lever 31 of the first activation lever 33 rotates counterclockwise around the first locating shaft 102, due to the structure of eccentric throw L, make the first rotating lever 31 the first eccentric orfice 3102 can be driven to rotate around the first locating shaft 102 around the rotation of the first locating shaft 102, the rotation of the first eccentric orfice 3102 drives the first extension spring 21 displacement to the right, the elastic force strain of the first extension spring 21 being produced due to this displacement is greater than the reset force of the first dropout semiaxis 101, the latched position that the first operating mechanism 1 closes a floodgate is forbidden so the spring energy of the first extension spring 21 drives the first dropout semiaxis 101 to move to.Be understood that, first extension spring

displacement (to right translation) of the second extension spring 91, two of feature is that the strain that this displacement makes the second extension spring 91 produce increases, and the elastic force that this strain produces is greater than the reset force of the second dropout semiaxis 701.
See the situation of Fig. 5 to Fig. 8 second embodiment, first Elastic Coupling part is first spring 22, one end of first spring 22 is first couple end, this first couples end and to contact with the first dropout semiaxis 101 and coordinate to form flexible couplings, the other end of first spring 22 is the first link, this first link is fixedly connected with to form driving syndeton with the first rotating lever 31, and is provided with the arm of force between one end of first spring 22 and the first positioning shaft hole 3101 apart from D.Similar, second Elastic Coupling part is second spring 92, one end of second spring 92 is second couple end, this second couples end and to contact with the second dropout semiaxis 701 and coordinate to form flexible couplings, the other end of second spring 92 is the second link, this second link is fixedly connected with to form driving syndeton with the second rotating lever 51, and is provided with the arm of force between one end of second spring 92 and the second positioning shaft hole 5101 apart from D.The employing sheet spring further illustrating the second embodiment below in conjunction with Fig. 5 to Fig. 8 is the operation principle of the interlock of the automatic transfer switching electric appliance of the present utility model of Elastic Coupling part.
The first operating mechanism 1 shown in Fig. 5 and Fig. 6 and second operation machine structure 7 are in same operating state, namely the first operating mechanism 1 is in gate-dividing state and is

operation state), its second dropout semiaxis 701 is in the unlocked position.See Fig. 5 and Fig. 7, the first activation lever 33 that the closing operation of second operation machine structure 7 makes the second cantilever 7031 in its second rotating shaft 703 promote the first lever assembly 3 moves, mobile promotion first rotating lever 31 of the first activation lever 33 rotates counterclockwise around the first locating shaft 102, because first spring 22 is fixed on the first rotating lever 31, and be provided with the arm of force between one end of first spring 22 (namely first coupling end) and the first positioning shaft hole 3101 apart from D, make the rotation of the first rotating lever 31 drive first of first spring 22 to couple end to rotate around the first locating shaft 102, namely first spring 22 produces the angular displacement that is fulcrum with the first locating shaft 102, this displacement makes first spring 22 contact with the first dropout semiaxis 101 and produce strain, and the elastic force that this strain produces is greater than the reset force of the first dropout semiaxis 101, the latched position that the first operating mechanism 1 closes a floodgate is forbidden so the spring energy of first spring 22 drives the first dropout semiaxis 101 to move to.Be understood that, first spring 22 drives the first dropout semiaxis 101 to move to latched position from unlocked position, wherein implicit two architectural features: one of feature is the global displacement (angular displacement counterclockwise as shown in the figure) of first spring 22, two of feature is that the strain that this displacement makes the first extension spring 21 produce increases, and the elastic force that this strain produces is greater than the reset force of the first dropout semiaxis 101.Certainly, in this locked condition, if first spring 22 rotates clockwise under the driving of the first rotating lever 31, so this rotation can make the strain of first spring 22 reduce or disappear, the reduction of this strain or disappearance make the elastic force of first spring 22 reduce or disappear and be less than the reset force of the first dropout semiaxis 101, thus make the first dropout semiaxis 101 get back to unlocked position under the effect of its reset force, this wherein also implies two architectural features: one of feature is moving integrally (as angular displacement clockwise) of first spring 22, two of feature is that this displacement makes the strain of first spring 22 reduce or disappear, and the elastic force that this strain produces is less than the reset force of the first dropout semiaxis 101.See Fig. 6 and Fig. 8, the second activation lever 53 that the sub-switching operation of the first operating mechanism 1 makes the first cantilever 1031 in its first rotating shaft 103 promote the second lever assembly 5 moves and orders about the second rotating lever 51 and rotates clockwise around the second locating shaft 702 and get back to shown position, because second spring 92 is fixed on the second rotating lever 51, and be provided with the arm of force between one end of second spring 92 (first couples end) and the second positioning shaft hole 7101 apart from D, make the rotation of the second rotating lever 51 drive second of second spring 92 to couple end to rotate around the second locating shaft 702, namely second spring 92 produces the angular displacement that is fulcrum with the second locating shaft 702, second spring 92 is separated with the second dropout semiaxis 701 in this displacement and strain disappears, the disappearance of this strain makes the elastic force of second spring 92 be less than the reset force of the second dropout semiaxis 701, so the second dropout semiaxis 701 gets back to the unlocked position can not forbidding that second operation machine structure 7 closes a floodgate under the effect of the reset force of himself.Be understood that, second spring 92 makes the second dropout semiaxis 701 get back to unlocked position from latched position, wherein implicit two architectural features: one of feature is moving integrally (to left) of second spring 92, two of feature is that this moves the strain disappearance or reduction that make second spring 92, and the elastic force that this strain produces is less than the reset force of the second dropout semiaxis 701.Certainly, under this released state, if second spring 92 under the driving of the second rotating lever 51 to rotating counterclockwise, so this rotation can make second spring 92 contact with the second dropout semiaxis 701 and strain is increased, the increase of this strain makes the elastic force of second spring 92 increase to be greater than the reset force of the second dropout semiaxis 701, thus make the second dropout semiaxis 701 be moved to latched position in the elastic force effect of the second spring 92, wherein also imply two architectural features: one of feature is the global displacement (counterclockwise angular displacement) of second spring 92, two of feature is that the strain that this displacement makes second spring 92 produce increases, and the elastic force that this strain produces is greater than the reset force of the second dropout semiaxis 701.
