[0066] Of course, as shown in Figures 4-7 and 12-15, the operating mechanism can also be in the double open position, that is, both electromagnetic driving mechanisms 2 are in the second position, the linkage assemblies 3 connected between each electromagnetic driving mechanism 2 and the output shaft 8 are in the second state, at this time, both output shafts 8 are rotated to the open position, but both electromagnetic driving mechanisms 2 cannot be in the first position at the same time, that is, both output shafts 8 will not be rotated to the closed position at the same time.

[0067] The improvement of the present application is that, as shown in Figures 2-25As shown, the operating mechanism further comprises a transmission mechanism, the transmission mechanism comprises a transmission assembly and two self-locking elastic members 4, the transmission assembly is drivingly connected between the two sets of link assemblies 3, and each self-locking elastic member 4 is connected to the link assembly 3 for locking the state of the link assembly 3, when the operating mechanism is in the first or second on position, one of the electromagnetic driving mechanisms 2 is switched to the first position and the connected link assembly 3 is switched to the first state, the link assembly 3 drives the connected self-locking elastic member 4 to switch to the first balanced state when switched to the first state, and the other electromagnetic driving mechanism 2 is in the second position and the connected link assembly 3 is locked in the second state by the self-locking elastic member 4 in the second balanced state.

[0068] In this way, the transmission assembly in the transmission mechanism is used to link the two electromagnetic driving mechanisms 2, ensuring that the two electromagnetic driving mechanisms 2 remain in the correct position during operation, and the self-locking elastic member 4 changes state with the switching of the state of the link assembly 3, thereby locking the link assembly 3, and the overall structure is simple, convenient to operate and has high reliability.

[0069] Further, as shown in Figs. 7 and 12-15, the operating mechanism can also be in a double split position, at this time, each electromagnetic driving mechanism 2 is in the second position and the connected link assembly 3 is respectively locked in the second state by the self-locking elastic member 4 in the second balanced state. Figure 2

[0070] Specifically, the link assembly 3 comprises a first link 31 and a second link 32, one end of the first link 31 is provided with a sliding shaft 35, the sliding shaft 35 is in sliding fit with a sliding groove 322 provided on the second link 32, the other end of the first link 31 is driven to swing by the electromagnetic driving mechanism 2, the other end of the second link 32 is connected with the output shaft 8, when the link assembly is in the first state, the sliding shaft 35 is located at a position away from the output shaft 8 in the sliding groove 322, so that the first link 31 and the second link 32 are arranged at an angle, when the link assembly 3 is in the second state, the sliding shaft 35 is located at a position close to the output shaft 8 in the sliding groove 322, so that the first link 31 and the second link 32 are arranged along approximately the same straight line, that is, when the link assembly 3 is in the first state, one end of the first link 31 and the second link 32 are hingedly connected at an angle through the sliding shaft 35, and the angle is preferably an acute angle, when the link assembly 3 is in the second state, the angle between the first link 31 and the second link 32 is an obtuse angle, and preferably, when the link assembly 3 is in the second state, the first link 31, the sliding shaft 35 and the second link 32 are arranged along approximately the same straight line, and the switching of the link assembly 3 from the first state to the second state can be understood as the switching of the angle between the first link 31 and the second link 32 from an acute angle to an obtuse angle, and when the angle between the first link 31 and the second link 32 is a right angle, it can be considered as the dead point position of the link assembly 3.

[0071] Preferably, as shown in​Figure 14 、 15 , 21, 24 and 25, the connecting rod assembly 3 also includes a third connecting rod 33 and a track groove 14, wherein one end of the third connecting rod 33 is hinged to the first connecting rod 31 through a linkage shaft 34, and the other end of the third connecting rod 33 is linked to the moving iron core 21 of the electromagnetic drive mechanism 2, and the linkage shaft 34 is slidably matched with the track groove 14, and the track groove 14 limits the track of the linkage shaft 34 swinging with the first connecting rod 31, and the track groove 14 can be opened on a fixed component that plays a supporting role.

[0072] like Figures 3-4 As shown in , 8, 12, 16-18 and 22, the self-locking elastic member 4 is connected to the first connecting rod 31, that is, one end of the self-locking elastic member 4 is connected to the first connecting rod 31, and the other end is fixedly connected, so that the self-locking elastic member 4 switches between the first equilibrium state and the second equilibrium state as the first connecting rod 31 swings. Usually, the self-locking elastic member 4 is a tension spring, one end of the self-locking elastic member 4 is connected to the middle part of the first connecting rod 31, and the other end is connected to a fixed component. When the first connecting rod 31 is driven to rotate by the electromagnetic drive mechanism 2, the first connecting rod 31 can drive the connected self-locking elastic member 4 to switch between the first equilibrium state and the second equilibrium state, wherein the first equilibrium position and the second equilibrium position are respectively located on both sides of the dead point position, that is, each self-locking elastic member 4 will cross the dead point position when switching between the first equilibrium state and the second equilibrium state (see Figure 8 、 12 , in the figure, the dead point position is indicated by a dotted line). In this embodiment, the dead point position is that the two ends of the self-locking elastic member 4 and the rotation center of the first connecting rod 31 are located in a straight line. If the self-locking elastic member 4 deviates from the dead point position during the movement, it is considered to be over the dead point.

Specifically, the plurality of transmission gears includes at least three gears rotatably assembled, one of which is the first gear 62, and the other two are the second gears 63, and the two second gears 63 are meshingly connected with each other. Each second gear 63 is connected with a transmission link 64, the first gear 62 is meshingly connected with one of the second gears 63, and the tripping piece 61 is drivingly connected with the first gear 62. By driving the tripping piece 61 to rotate between the original position and the unlocking position, the first gear 62 and the two second gears 63 are driven to rotate. In addition, when the operating mechanism is switched between the first on position or the second on position and the double off position, a compensation groove 641 is arranged on the transmission link 64, and the link assembly 3 is slidingly fitted with the compensation groove 641. When the tripping piece 61 is reset, the tripping piece 61 will drive the first gear 62 and the second gear 63 to rotate, and the link assembly 3 will slide in the compensation groove 641 during the rotation of the gears, so as to avoid the mutual interference between the tripping piece 61 and the link assembly 3. The rotation of the tripping piece 61 can be manually driven, for example, by a button arranged on the tripping piece 61 to drive the rotation, or the rotation of the tripping piece 61 can be automatically driven, for example, by the split brake electromagnetic mechanism 7.

[0074] Preferably, as shown in Figures 16-25 The transmission assembly can also be the interlocking link 5, which is connected with the two linkage shafts 34. The interlocking link 5 keeps one of the electromagnetic drive mechanisms 2 in the first position and the other electromagnetic drive mechanism 2 in the second position. This structure has the advantages of simple structure, convenient interlocking and low cost. However, when the interlocking link 5 is used to lock the positions of the two electromagnetic drive mechanisms 2, the operating mechanism usually only has the first on position and the second on position, and does not have the double off position.

[0075] Further, the micro switch 9 can be arranged to feedback the position of the transmission mechanism, which can accurately and quickly feedback the position information, and also facilitate the control of the operation of the operating mechanism, for example, by controlling the power-on and power-off of the electromagnetic drive mechanism 2 in the operating mechanism through the micro switch 9, so as to realize accurate and rapid control.

When each connecting rod assembly 3 switches to the second position, the connecting rod assembly 3 drives the connected self-locking elastic member 4 to rotate to the second equilibrium state. When the self-locking elastic member 4 switches between the first equilibrium state and the second equilibrium state, the self-locking elastic member 4 passes the dead point position.

In this embodiment, the linkage shaft 34 is located at the end of the track groove 14 close to the electromagnetic drive mechanism 2.

[0087] In this embodiment, if Figures 2-15As shown in FIG30 , the tripping electromagnetic mechanism 7 can adopt an existing electromagnetic mechanism, that is, the tripping electromagnetic mechanism 7 also includes a coil assembly, the coil assembly includes a coil skeleton and a coil wound on the outside of the coil skeleton, and a magnetic yoke is also provided on the outside of the coil assembly. A tripping static iron core is provided at one end of the coil assembly, and a tripping moving iron core 73 is slidingly provided in the middle of the coil assembly. A through hole is provided in the middle of the tripping static iron core, and a push rod passing through the through hole is provided at one end of the tripping moving iron core 73 facing the tripping static iron core, and a tripping connecting rod 72 is connected to the push rod. When the tripping electromagnetic mechanism 7 is energized, the push rod 73 of the tripping moving iron core is pushed The rod can extend from the through hole, thereby driving the tripping member 61, so that the tripping moving iron core 73 is driven and connected to the tripping member 61 through the tripping connecting rod 72; further, a tripping reset member 71 is connected between the tripping member 61 and the tripping electromagnetic mechanism 7. In the figure, the tripping reset member 71 is a spring, and one end of the tripping reset member 71 is connected to the fixed part of the tripping electromagnetic mechanism 7, for example, a reset connection part 74 is provided on the yoke and / or the coil skeleton in the coil assembly, and one end of the tripping reset member 71 is connected to the reset connection part 74. When the tripping electromagnetic mechanism 7 drives the tripping member 61 from its original position (see Figures 2-11 ) to the unlocked position (see Figures 12-15 ), the tripping member 61 can be driven by the opening reset member 71 to rotate from the unlocked position to the original position.

[0088] The release member 61 is rotatably assembled in the assembly cavity 10 and can drive the first gear 62 to rotate. Figures 2-15 In the embodiment, the release member 61 and the first gear 62 are coaxially rotated and assembled, and the first gear 62 rotates together with the release member 61. Two meshing second gears 63 are arranged side by side between the two sets of connecting rod assemblies 3, and one of the second gears 63 is meshed and connected with the first gear 62. Figures 2-15 In the embodiment, the second gear 63 on the common side is meshed with the first gear 62, as shown in FIG. Figures 2-15 As shown in Figure 29, a transmission link 64 is linked to the connecting rod assembly 3 and the second gear 63, and a compensation groove 641 is provided in the middle of each transmission link 64. The linkage shaft 34 in the connecting rod assembly 3 slides in cooperation with the compensation groove 641. Furthermore, a driven link 65 is connected to each second gear 63, and the driven link 65 is linked to the transmission link 64. In this embodiment, the driven link 65 includes a closing half-shaft, which is fixedly connected to the axial center position of the second gear 63, and a rod body with a slightly bent end extending radially outward from the side wall of the closing half-shaft, and the rod body is used to be linked to the transmission link 64.

[0089] When the operating mechanism is in the double-open position, the tripping member 61 is in the original position, and the two connecting rod assemblies 3 are in the second state. At this time, the two linkage shafts 34 are located in the compensation groove 641 near the end of the second gear 63; when the operating mechanism is in the first connection position or the second connection position, the transmission mechanism state remains unchanged, and the linkage shaft 34 in the connecting rod assembly 3 in the first state moves along the track groove 14 while also moving in the compensation groove 641, that is, the linkage shaft 34 moves from the end close to the second gear 63 to the end away from the second gear 63; when the operating mechanism needs to switch from the first connection position or the second connection position to the double-open position, the opening electromagnetic mechanism 7 is energized to drive the tripping member 6 1 rotates from the original position to the open position, thereby, the first gear 62 drives the two second gears 63 in sequence, one of the second gears 63 drives the linkage shaft 34 through the compensation groove 641 of the transmission connecting rod 64, so that the connecting rod assembly 3 in the first state is switched to the second state. As the connecting rod assembly 3 switches from the first state to the second state, the connecting rod assembly 3 can drive the movable iron core 21 in the connected electromagnetic drive mechanism 2 to reset. At the same time, during the rotation of the other second gear 63, due to the presence of the compensation groove 641, the linkage shaft 34 in the connecting rod assembly 3 in the second state only moves within the compensation groove 641, and cannot switch the connecting rod assembly 3 in the second state.

[0090] The specific working process is:

[0091] like Figures 2-7 As shown, in the double-split position, the electromagnetic drive mechanisms 2 on the common side and the standby side are both in the second position, and the two groups of connecting rod assemblies 3 are in the second state, that is, the first connecting rod 31, the sliding shaft 35 and the second connecting rod 32 are arranged along the direction of approximately the same straight line, and the sliding shaft 35 is located at one end of the slide groove 322 close to the output shaft 8. The linkage shaft 34 in each connecting rod assembly 3 is correspondingly located at one end of the respective track groove 14 away from the electromagnetic drive mechanism 2 and presses the corresponding opening switch, and the linkage shaft 34 is also correspondingly located at one end of the respective compensation groove 641 close to the second gear 63. The self-locking elastic member 4 on each connecting rod assembly 3 is in the second equilibrium state for locking the connecting rod assembly 3.

[0092] like Figures 8-11As shown, when switching from the double-break position to the first on position, the electromagnetic drive mechanism 2 of the normal side is in the first position, the linkage assembly 3 of the normal side is driven by the electromagnetic drive mechanism 2 of the normal side to switch from the second state to the first state, that is, the first linkage 31 and the second linkage 32 of the normal side are arranged at an acute angle, at this time, the contact system connected to the second linkage 32 generates a counterforce on the linkage assembly 3, when the first linkage 31 and the second linkage 32 are at an acute angle, the counterforce of the contact system cannot make the first linkage 31 rotate to the double-break position, at this time, it can be understood that the first linkage 31 and the second linkage 32 are locked at the acute angle state, in this embodiment, switching from the second state to the first state can be understood as that the angle between the first linkage 31 and the second linkage 32 changes from an obtuse angle, a right angle to an acute angle, when the first linkage 31 and the second linkage 32 are at a right angle, it can be considered that the linkage assembly 3 is at its own dead point position; the sliding shaft 35 moves from the end close to the output shaft 8 to the end away from the output shaft 8 of the sliding groove 322, the linkage shaft 34 moves from the end away from the electromagnetic drive mechanism 2 to the end close to the electromagnetic drive mechanism 2 of the track groove 14, after the linkage shaft 34 is pressed to the closing switch, the electromagnetic drive mechanism 2 of the normal side is powered off, when the linkage assembly 3 switches the state, the self-locking elastic member 4 on the linkage assembly 3 of the normal side is driven by the linkage assembly 3 to switch from the second balance state to the first balance state after passing through the dead point position, the elastic force of the self-locking elastic member 4, the linkage assembly 3 and the contact system on the output shaft 8 cooperate to lock the linkage assembly 3 in the first state; at the same time, the linkage shaft 34 of the normal side slides along the compensation groove 641 to the edge of the compensation groove 641 for preparation for breaking, as shown in Figure 11 As shown, the linkage shaft 34 moves to the side of the compensation groove 641 close to the electromagnetic drive mechanism 2 of the normal side (the side away from the driven linkage 65), at the same time, when the linkage shaft 34 slides along the compensation groove 641, it does not drive the transmission assembly, that is, the tripping member 61 is still in the original position, the first gear 62 and the second gear 63 are not in action, and the electromagnetic drive mechanism 2, the linkage assembly 3 and the self-locking elastic member 4 of the standby side are not in action.

[0093] As shown, Figures 12-15 When the operating mechanism needs to switch from the first on position to the double-break position, the breaking electromagnetic mechanism 7 is powered to drive the tripping member 61 to switch from the original position to the unlocking position, the tripping member 61 drives the first gear 62 to rotate in the counterclockwise direction in Figure 12 , the second gear 63 of the normal side and the second gear 63 of the standby side are driven to rotate in turn, wherein the second gear 63 of the normal side rotates in the counterclockwise direction in Figure 12clockwise direction in the figure, the second gear 63 of the standby side drives the transmission connecting rod 64 to move, but because of the existence of the compensation slot 641 on the transmission connecting rod 64, the linkage shaft 34 in the connecting rod assembly 3 of the standby side moves in the compensation slot 641, so that the second gear 63 of the standby side does not drive the moving iron core 21, the connecting rod assembly 3 and the self-locking elastic member 4 of the electromagnetic drive mechanism 2 of the standby side in the process. After the opening electromagnetic mechanism 7 is powered off, the opening reset member 71 drives the tripping member 61 to move from the unlocking position to the original position, in the process, the first gear 62 and the two second gears 63 are driven to rotate, that is, in the figure, the first gear 62 and the second gear 63 of the standby side rotate in the clockwise direction, and the second gear 63 of the commonly used side rotates in the counterclockwise direction, the compensation slot 641 on the transmission connecting rod 64 of each second gear 63 is in sliding fit with the linkage shaft 34 in the two connecting rod assemblies 3 at this time, and the two linkage shafts 34 are finally located at the side close to the electromagnetic drive mechanism 2 (the side away from the transmission connecting rod 65) of the respective compensation slot 641, avoiding the mutual interference between the tripping member 61 and the connecting rod assembly 3. Figure 12 clockwise direction in the figure, the second gear 63 of the standby side drives the transmission connecting rod 64 to move, but because of the existence of the compensation slot 641 on the transmission connecting rod 64, the linkage shaft 34 in the connecting rod assembly 3 of the standby side moves in the compensation slot 641, so that the second gear 63 of the standby side does not drive the moving iron core 21, the connecting rod assembly 3 and the self-locking elastic member 4 of the electromagnetic drive mechanism 2 of the standby side in the process. After the opening electromagnetic mechanism 7 is powered off, the opening reset member 71 drives the tripping member 61 to move from the unlocking position to the original position, in the process, the first gear 62 and the two second gears 63 are driven to rotate, that is, in the figure, the first gear 62 and the second gear 63 of the standby side rotate in the clockwise direction, and the second gear 63 of the commonly used side rotates in the counterclockwise direction, the compensation slot 641 on the transmission connecting rod 64 of each second gear 63 is in sliding fit with the linkage shaft 34 in the two connecting rod assemblies 3 at this time, and the two linkage shafts 34 are finally located at the side close to the electromagnetic drive mechanism 2 (the side away from the transmission connecting rod 65) of the respective compensation slot 641, avoiding the mutual interference between the tripping member 61 and the connecting rod assembly 3. Figure 12 clockwise direction in the figure, the second gear 63 of the standby side drives the transmission connecting rod 64 to move, but because of the existence of the compensation slot 641 on the transmission connecting rod 64, the linkage shaft 34 in the connecting rod assembly 3 of the standby side moves in the compensation slot 641, so that the second gear 63 of the standby side does not drive the moving iron core 21, the connecting rod assembly 3 and the self-locking elastic member 4 of the electromagnetic drive mechanism 2 of the standby side in the process. After the opening electromagnetic mechanism 7 is powered off, the opening reset member 71 drives the tripping member 61 to move from the unlocking position to the original position, in the process, the first gear 62 and the two second gears 63 are driven to rotate, that is, in the figure, the first gear 62 and the second gear 63 of the standby side rotate in the clockwise direction, and the second gear 63 of the commonly used side rotates in the counterclockwise direction, the compensation slot 641 on the transmission connecting rod 64 of each second gear 63 is in sliding fit with the linkage shaft 34 in the two connecting rod assemblies 3 at this time, and the two linkage shafts 34 are finally located at the side close to the electromagnetic drive mechanism 2 (the side away from the transmission connecting rod 65) of the respective compensation slot 641, avoiding the mutual interference between the tripping member 61 and the connecting rod assembly 3.

[0094] When the switch is switched from the double-break position to the second on position, the electromagnetic drive mechanism 2 on the standby side is in the first position, the linkage assembly 3 on the standby side is switched from the second state to the first state by the electromagnetic drive mechanism 2 on the standby side, that is, the first linkage 31 on the standby side and the second linkage 32 are arranged at an acute angle, the first linkage 31 on the standby side and the second linkage 32 are arranged at an acute angle, and the functions of the linkage assembly 3 on the standby side are the same as those of the linkage assembly 3 on the standby side, which are used to lock the first linkage 31 and the second linkage 32, the sliding shaft 35 moves from the end of the sliding groove 322 close to the output shaft 8 to the end away from the output shaft 8, the linkage shaft 34 moves from the end of the track groove 14 away from the electromagnetic drive mechanism 2 to the end close to the electromagnetic drive mechanism 2, after the linkage shaft 34 is pressed to the closing switch, the electromagnetic drive mechanism 2 on the standby side is powered off, when the linkage assembly 3 switches the state, the self-locking elastic member 4 on the standby side linkage assembly 3 is driven by the linkage assembly 3 to switch from the second balance state to the first balance state after passing through the dead point position, the elastic force of the self-locking elastic member 4, the linkage assembly 3 and the switch on the output shaft 8 cooperate to lock the linkage assembly 3 in the first state; at the same time, the linkage shaft 34 on the standby side slides along the compensation groove 641 to the edge of the compensation groove 641 for preparation for opening, the linkage shaft 34 moves to the end of the compensation groove 641 close to the electromagnetic drive mechanism 2 on the standby side (away from the end of the driven linkage 65), at the same time, when the linkage shaft 34 slides along the compensation groove 641, it does not drive the transmission assembly, that is, the trip unit 61 is still in the original position, the first gear 62 and the second gear 63 are not in action, the electromagnetic drive mechanism 2, the linkage assembly 3 and the self-locking elastic member 4 on the standby side are not in action.

[0095] When the operating mechanism needs to switch from the second on position to the double break position, the break electromagnetic mechanism 7 is powered to drive the tripping piece 61 to switch from the original position to the unlocking position. The tripping piece 61 drives the first gear 62 to rotate counterclockwise, and the second gears 63 of the normally used side and the standby side are sequentially driven to rotate, that is, the second gear 63 of the normally used side rotates in the clockwise direction, and the second gear 63 of the standby side rotates in the counterclockwise direction. The second gear 63 of the normally used side rotates to drive the transmission connecting rod 64 connected thereto to move. During the movement of the transmission connecting rod 64, the connecting shaft 34 of the normally used side slides in the compensation slot 641 of the normally used side, so that the linkage assembly 3 of the normally used side does not change state during this process. The second gear 63 of the standby side rotates to drive the transmission connecting rod 64 connected thereto to drive the linkage assembly 3 of the standby side to move. The linkage shaft 34 is driven to move from the end close to the standby side electromagnetic driving mechanism 2 to the end away from the standby side electromagnetic driving mechanism 2 along the track slot 14, until the linkage shaft 34 of the standby side is pressed to the break switch to control the break electromagnetic mechanism 7 to be powered off. During this process, the linkage assembly 3 of the standby side is switched from the first state to the second state, that is, the sliding shaft 35 moves from the end away from the output rotating shaft 8 to the end close to the output rotating shaft 8 along the sliding slot 322, so that the sliding shaft 35, the first connecting rod 31 and the second connecting rod 32 are arranged in approximately the same straight line. With the switching of the linkage assembly 3 of the standby side, the self-locking elastic piece 4 connected thereto is switched from the first balance state to the second balance state through the dead point position. When the break electromagnetic mechanism 7 is powered off, the break reset piece 71 drives the tripping piece 61 to move from the unlocking position to the original position. During this process, the first gear 62 and the two second gears 63 are driven to rotate, that is, in the first embodiment, the first gear 62 and the second gear 63 of the standby side rotate in the clockwise direction, and the second gear 63 of the normally used side rotates in the counterclockwise direction. The compensation slot 641 on the transmission connecting rod 64 on each second gear 63 is in sliding fit with the linkage shaft 34 of the two linkage assemblies 3 at this time, and the linkage shaft 34 of the two linkage assemblies 3 is located at the end of the respective compensation slot 641 away from the respective electromagnetic driving mechanism 2 (close to the end of the transmission connecting rod 65), to avoid mutual interference between the tripping piece 61 and the linkage assembly 3. Figure 12

[0098] In the embodiment, a transmission mechanism is further arranged in the assembling cavity 10, the transmission mechanism includes two self-locking elastic members 4, the self-locking elastic member 4 and the matching mode of the self-locking elastic member 4 and the connecting rod assembly 3 are the same as those in the first embodiment, correspondingly, the track groove 14 matched with the self-locking elastic member 4 and the support plate 13 are also the same as those in the first embodiment, and the transmission mechanism further includes an interlocking connecting rod 5, the interlocking connecting rod 5 is connected between the linkage shafts 34 of the two connecting rod assemblies 3, and the interlocking connecting rod 5 keeps one of the electromagnetic driving mechanisms 2 in the first position and the other electromagnetic driving mechanism 2 in the second position, in the figure, the interlocking connecting rod 5 is in a straight rod structure, and a through hole is arranged at each end of the interlocking connecting rod 5 for the linkage shaft 34 to pass through, in the embodiment, the operating mechanism only has a first connection position and a second connection position, that is, when the moving iron core 21 of one of the electromagnetic driving mechanisms 2 moves to the first position close to the static iron core 22, since the length of the interlocking connecting rod 5 is fixed, the moving iron core 21 of the other electromagnetic driving mechanism 2 is driven to the second position away from the static iron core 22, so that the two electromagnetic driving mechanisms 2 always keep one in the first position and the other in the second position, and thus there is no double split position.

[0099] The specific process is as follows,

[0100] As Figures 16-21As shown, in the first on position, the electromagnetic drive mechanism 2 of the normal side is in the first position, the linkage assembly 3 of the normal side is driven by the electromagnetic drive mechanism 2 of the normal side to switch from the second state to the first state, that is, the first linkage 31 and the second linkage 32 of the normal side are arranged at an acute angle, the sliding shaft 35 moves from the end of the sliding groove 322 close to the output shaft 8 to the end away from the output shaft 8, and the linkage shaft 34 moves from the end of the track groove 14 away from the electromagnetic drive mechanism 2 to the end close to the electromagnetic drive mechanism 2. After the linkage shaft 34 is pressed to the closing switch, the electromagnetic drive mechanism 2 of the normal side is powered off. When the linkage assembly 3 switches the state, the self-locking elastic member 4 on the linkage assembly 3 of the normal side is driven by the linkage assembly 3 to switch from the second balance state to the first balance state after passing through the dead point position. The elastic force of the self-locking elastic member 4, the linkage assembly 3 and the contact system on the output shaft 8 cooperate to lock the linkage assembly 3 in the first state. At the same time, the linkage shaft 34 of the normal side drives the interlocking linkage 5 to move as a whole to the direction close to the electromagnetic drive mechanism 2 of the normal side. The interlocking linkage 5 drives the moving iron core 21 of the electromagnetic drive mechanism 2 of the standby side to move to the position away from the static iron core 22 in the process, that is, the electromagnetic drive mechanism 2 of the standby side switches from the first position to the second position. The linkage assembly 3 of the standby side switches from the first state to the second state in the process. The first linkage 31, the sliding shaft 35 and the second linkage 32 of the standby side are arranged in the direction of approximately the same straight line. The self-locking elastic member 4 of the standby side switches from the first balance state to the second balance state after passing through the dead point position. The self-locking elastic member 4 of the standby side can lock the linkage assembly 3 of the standby side in the second state.
