[0030] Exemplarily, the elastic element 142 can be a torsion spring, a spring, a spring piece or other elements capable of storing elastic potential energy, and is not specifically limited here.

[0031] Exemplarily, the connection between the second rod part 123 and the moving contact 210 can be direct connection or indirect connection, which is not limited here.

[0032] Exemplarily, the driving of the driving shaft 154 can be driven by manpower, or driven by a rotating motor, a driving motor or the like, and the power source of the driving shaft 154 is not limited here.

[0033] It should be noted that “the first guide hole 111 is arranged close to the first hole part 1131, and the second guide hole 112 is arranged close to the third hole part 1133” can be understood as that the first guide hole 111 and the first hole part 1131 are located on the same side, and the second guide hole 112 and the third hole part 1133 are located on the same side. “Movable connection” can be understood as that the relative position between two objects can change, that is, the relative position between the two objects is not in a fixed state, that is, one of the objects can move relative to the other object.

[0034] For the convenience of description, the first rotation direction X1, the second rotation direction X2, the third rotation direction X3, the fourth rotation direction X4, the first sliding direction Y1 and the second sliding direction Y2 are defined here. The first rotation direction X1 and the second rotation direction X2 are opposite, the third rotation direction X3 and the fourth rotation direction X4 are opposite, and the first sliding direction Y1 and the second sliding direction Y2 are opposite. It can be understood that the working principle of the operating mechanism 100 provided in the embodiment is as follows: As shown in Figures 7 to 10 When the driving shaft 154 rotates along the first rotation direction X1, the third sliding part 153 slides along the first sliding direction Y1 under the driving of the driving shaft 154, and drives the second rotating part 131 to rotate along the third rotation direction X3 through the fourth rod part 133. With the rotation of the second rotating part 131 along the third rotation direction X3, one end of the elastic part 142 is moved to store elastic potential energy, until the fifth rod part 134 abuts against the second sliding part 152. At this time, the second sliding part 152 slides along the second guide hole 112 under the driving of the fifth rod part 134 to abut against the first transmission shaft 141. The first transmission shaft 141 slides into the second hole part 1132 from the third hole part 1133 under the driving of the second sliding part 152. At this time, the elastic potential energy is released, and the other end of the elastic part 142 drives the first transmission shaft 141 to slide into the first hole part 1131 along the second hole part 1132. Under the driving of the first transmission shaft 141, the first rod part 122 drives the first rotating part 121 to rotate along the fourth rotation direction X4. With the rotation of the first rotating part 121 along the fourth rotation direction X4, the second rod part 123 drives the moving contact 210 to open.

[0035] As shown in Figure 7 , Figure 8 ,Figure 11 and Figure 12 As shown in FIGS. 1 1, 12, 13 and 14, when the driving shaft 154 rotates along the second rotation direction X2, the third sliding piece 153 slides along the second sliding direction Y2 under the driving of the driving shaft 154, and drives the second rotation part 131 to rotate along the fourth rotation direction X4 through the fourth rod part 133. With the rotation of the second rotation part 131 along the fourth rotation direction X4, one end of the elastic piece 142 is driven to move by the third rod part 132 to store elastic potential energy, until the fifth rod part 134 abuts against the first sliding piece 151. At this time, the first sliding piece 151 slides along the first guide hole 111 under the driving of the fifth rod part 134 to abut against the first transmission shaft 141. The first transmission shaft 141 slides into the second hole part 1132 from the first hole part 1131 under the driving of the first sliding piece 151. At this time, the other end of the elastic piece 142 drives the first transmission shaft 141 to slide into the third hole part 1133 along the second hole part 1132. Under the driving of the first transmission shaft 141, the first rod part 122 drives the first rotation part 121 to rotate along the third rotation direction X3. With the rotation of the first rotation part 121 along the third rotation direction X3, the second rod part 123 drives the movable contact 210 to close.

[0036] In the above action process, the elastic piece 142 stores elastic potential energy through the rotation of the driving shaft 154. The release of the elastic potential energy can quickly drive the movable contact 210 to close or open. In this way, the effects of quick opening and quick closing are achieved, the on-off performance of the switch device 1000 is improved, and the reliability and service life of the switch device 1000 are improved.

[0037] As shown in FIGS. 1 1, 12, 13 and 14, when the driving shaft 154 rotates along the second rotation direction X2, the third sliding piece 153 slides along the second sliding direction Y2 under the driving of the driving shaft 154, and drives the second rotation part 131 to rotate along the fourth rotation direction X4 through the fourth rod part 133. With the rotation of the second rotation part 131 along the fourth rotation direction X4, one end of the elastic piece 142 is driven to move by the third rod part 132 to store elastic potential energy, until the fifth rod part 134 abuts against the first sliding piece 151. At this time, the first sliding piece 151 slides along the first guide hole 111 under the driving of the fifth rod part 134 to abut against the first transmission shaft 141. The first transmission shaft 141 slides into the second hole part 1132 from the first hole part 1131 under the driving of the first sliding piece 151. At this time, the other end of the elastic piece 142 drives the first transmission shaft 141 to slide into the third hole part 1133 along the second hole part 1132. Under the driving of the first transmission shaft 141, the first rod part 122 drives the first rotation part 121 to rotate along the third rotation direction X3. With the rotation of the first rotation part 121 along the third rotation direction X3, the second rod part 123 drives the movable contact 210 to close. Figure 1 Figure 4 Figure 6 As shown in FIGS. 1 1, 12, 13 and 14, when the driving shaft 154 rotates along the second rotation direction X2, the third sliding piece 153 slides along the second sliding direction Y2 under the driving of the driving shaft 154, and drives the second rotation part 131 to rotate along the fourth rotation direction X4 through the fourth rod part 133. With the rotation of the second rotation part 131 along the fourth rotation direction X4, one end of the elastic piece 142 is driven to move by the third rod part 132 to store elastic potential energy, until the fifth rod part 134 abuts against the first sliding piece 151. At this time, the first sliding piece 151 slides along the first guide hole 111 under the driving of the fifth rod part 134 to abut against the first transmission shaft 141. The first transmission shaft 141 slides into the second hole part 1132 from the first hole part 1131 under the driving of the first sliding piece 151. At this time, the other end of the elastic piece 142 drives the first transmission shaft 141 to slide into the third hole part 1133 along the second hole part 1132. Under the driving of the first transmission shaft 141, the first rod part 122 drives the first rotation part 121 to rotate along the third rotation direction X3. With the rotation of the first rotation part 121 along the third rotation direction X3, the second rod part 123 drives the movable contact 210 to close.

[0038] ​​It can be understood that when the driving shaft 154 rotates along the first rotation direction X1, the second rotating part 131 can be rotated along the third rotation direction X3, so that the third rod part 132 drives the second transmission shaft 143 to slide into the fifth hole part 1142 from the sixth hole part 1143 and slide into the fourth hole part 1141 along the fifth hole part 1142, so that the elastic member 142 stores elastic potential energy to drive the movable contact 210 to open; when the driving shaft 154 rotates along the second rotation direction X2, the second rotating part 131 can be rotated along the fourth rotation direction X4, so that the third rod part 132 drives the second transmission shaft 143 to slide into the fifth hole part 1142 from the fourth hole part 1141 and slide into the sixth hole part 1143 along the fifth hole part 1142, so that the elastic member 142 stores elastic potential energy to drive the movable contact 210 to close.

[0039] It should be noted that the first hole part 1131 and the third hole part 1133 play a limiting role on the first transmission shaft 141, and the fourth hole part 1141 and the sixth hole part 1143 play a limiting role on the second transmission shaft 143, so that the operating mechanism 100 cannot easily switch from the closed state to the open state or from the open state to the closed state without rotating the driving shaft 154, which helps to improve the reliability of the switch device 1000.

[0040] As shown in Figure 10 and Figure 12 Further, the first rod part 122 is provided with a fifth guide hole 124, and the first transmission shaft 141 is arranged in the fifth guide hole 124, so that the first transmission shaft 141 is movably connected with the first rod part 122, thereby reducing the possibility of structural interference between the first transmission shaft 141 and the first rod part 122 during the movement of the first transmission shaft 141 between the first hole part 1131 and the third hole part 1133; the third rod part 132 is provided with a sixth guide hole 135, and the second transmission shaft 143 is arranged in the sixth guide hole 135, so that the second transmission shaft 143 is movably connected with the third rod part 132, thereby reducing the possibility of structural interference between the second transmission shaft 143 and the third rod part 132 during the movement of the second transmission shaft 143 between the fourth hole part 1141 and the sixth hole part 1143.

[0041] Of course, for the above-mentioned embodiments, a sliding block can also be provided on the first transmission shaft 141 and / or the second transmission shaft 143, and a guide rail matched with the sliding block can be provided on the first rod part 122 and / or the third rod part 132, which can also achieve the movable connection between the transmission shaft and the rod part.
