At the same time, as shown in Figure 3(a), a tripping projection 206 is provided on the outside of the second steering limit elastic block 202, and as shown in Figure 6(d), the energy storage lock block 10 corresponds to the The tripping bump 206 is provided with a tripping pusher 1002. When the energy storage lock block 10 is in the locked position, the tripping pusher 1002 is located below the tripping bump 206. When the electromagnetic drive mechanism 6 is connected to the disconnected When the signal is commanded, the energy storage lock block 10 is switched from the locked position to the unlocked position, and the tripping pusher 1002 pushes the tripping projection 206 to lift up, and at this time, the operating swivel seat 5 is free.

As shown in Figure 3(b), the outer side of the first driving arm 303 protrudes to form a linkage protrusion 304, as shown in Figure 4, when the operating mechanism is in the closed position, the second driving arm 503 Located on the movement path of the interlocking projection 304 from the closed state to the open state, it is specifically set to be adjacent to each other. Adjacent to each other means that the two are attached or there is a small gap between them. In this way, when the electromagnetic drive mechanism 6 receives the disconnect command signal, the operating swivel seat 5 is free, and in the process of the operating shaft rotating from the closed position to the disconnected position, the linkage projection 304 pushes the second drive arm 503, while the first The energy storage element will not store energy or only pull away the energy storage in a very small amount, so that during the cut-off process of the rotary switch, the first energy storage element 4 is always in the energy release state or is basically close to the energy release state. The operating shaft 3 basically does not form a resistance effect, and the external force driving the operating mechanism is only the elastic force of the second energy storage element 7 .

Specifically, the upper end of the second driving arm 503 has certain elasticity and can swing outward under the action of the linkage protrusion 304, and the side surfaces at both ends of the second driving arm 503 are provided with third guide surfaces 505, the linkage The side wall of the protrusion 304 relatively close to the closed state is the second guide surface 305 and the side wall relatively close to the open state is the linkage action surface 306 . When in the closed position, the linkage action surface 306 is adjacent to the second driving arm 503, and during the manual operation of the operating shaft rotating from the closed position to the open position, the operating swivel base 5 remains relatively stationary under the action of the stopper 2, The linkage action surface 306 acts on the third guide surface 505 on one side of the second driving arm 503, pushes the second driving arm 503 with certain elasticity and slides over the second driving arm 503, when the operating shaft rotates to the disconnected position , operate the swivel seat 5 to get free, and under the action of the energy release of the first energy storage element 4, rotate to the third guide surface 505 on the side where the second guide surface 305 is attached to the second driving arm 503, and then interact and push away the third guide surface 505 with The second driving arm 503 with certain elasticity slides over the second driving arm 503, and finally the swivel base 5 is operated to rotate to the disconnected position. The third guiding surface 505 can be a smooth convex surface as shown in the figure, or a smooth guiding inclined surface. The second guide surface 305 can be a smooth convex surface as shown in the figure, or a smooth guide slope. When the operating swivel base 5 is locked by the stopper 2, the linkage action surface 306 interacts with the third guide surface 505 under a certain external force to push away the second driving arm 503, and when the swivel seat 5 is operated to release the stopper 2. When the locking function is in effect, the interaction between the linkage action surface 306 and the second drive arm 503 will directly push the second drive arm 503 to rotate in the circumferential direction instead of pushing the second drive arm 503 away. The linkage action surface 306 can be specifically as shown in the figure A plane can also be an inner slope or an inner concave surface.

As shown in Figure 6(a), the second operating shaft 8 is fixed with an energy storage push block 802 and a locking push block through hole 803, as shown in Figure 6(c), the middle housing 102 An energy storage lock push block 106 is fixed on the top, the energy storage lock push block 106 passes through the lock push block through hole 803 and its end protrudes relative to the surface of the second operating shaft 8, and the energy storage lock push block 106 is close to 0 One side of the disconnected position of ° is provided with a first guide surface 107 (which can be a convex curved surface or an inclined surface, a convex curved surface in the figure) and a supporting plane 108 is provided at the top, and the first guide surface 107 is used for alignment along the first The energy storage arm moved by the guide surface 107 forms an active force along the axial direction; when the second operating shaft 8 is in the disconnected position of 0° and the energy storage arm is in the energy release position, the energy storage arm is positioned at the energy storage push block 802 rotates to the movement path of the closed position of a°, when the second operating shaft 8 is at the position of b°, the energy storage pushing block 802 is against the energy storage arm, and when the second operating shaft 8 rotates from the position of b° to During the position of c°, the energy storage push block 802 pushes the energy storage arm. When the second operation shaft 8 is at the position of c°, the energy storage push block 802 is against the first guide surface 107, and the second operation shaft 8 moves from During the rotation from the position of c° to the position of d°, the energy storage push block 802 pushes the energy storage arm, and the energy storage arm slides along the first guide surface 107 to lift it up, when the second operating shaft 8 is at d° position, the energy storage arm moves to the support plane 108 along the first guide surface 107. At this time, the energy storage arm is in the energy storage position, and the energy storage lock block 10 in the locked position forms a locking effect on the energy storage arm. At the same time, The energy storage arm is just higher than the energy storage push block 802, so the position of the energy storage arm is fixed to form an energy storage effect. At the same time, the energy storage push block 802 can move freely, that is, the second operating shaft 8 can be in the disconnected position and Free switching between closed positions, opening and closing can be operated manually, a≥d＞c＞b≥0.

When the second operating shaft 8 rotates from the open position of 0° to the closed position of a° at least in part of the path, the reset projection 902 pushes the second pushing part 1503, so that the rotating shaft part 1501 rotates around When its axis rotates, the first pushing part 1502 pushes the electromagnetic driving block 602 to make the magnet 605 close to the electromagnetic coil fixing part 601 , and finally makes the magnet 605 and the electromagnetic coil fixing part 601 be attracted. Through the above setting, the electromagnetic driving block 602 after the first action spring 603 is released can be restored to the normal state where the electromagnetic coil fixing part 601 is attracted to the magnet 605 and the first action spring 603 is squeezed and stored by both. state.

The above-mentioned electromagnetic drive reset transmission mechanism is composed of the transmission structure between the rack 9 and the reset crank arm 15 and the magnetic attraction force between the electromagnetic coil fixing member 601 and the magnet 605 .

The magnetic attraction force between the electromagnetic coil fixing part 601 and the magnet 605 will be seriously affected by the distance between the two. If the electromagnetic drive block 602 is to be reset by the self-attraction force of the magnet 605, the distance between the two needs to be controlled to a small range. , the electromagnetic drive block 602 can be reset through the magnetic drive reset transmission mechanism of this embodiment.
