[0045] When it is needed to drive the first upper moving plate 1 and the second upper moving plate 2 to move upwards and the first lower moving plate 3 and the second lower moving plate 4 to move downwards, the worker lifts one end of the upper drive rod 501 connected with the first upper moving rod 502 upwards, at this time, the first upper moving rod 502 moves upwards, drives the first upper connecting rod 503 to move upwards along the upper strip-shaped hole 506, and drives the first upper sleeve 7 to move upwards and further drives the first upper moving plate 1 to move upwards, so that the upper stationary contact group is exposed; when the first upper connecting rod 503 moves to the top end in the upper strip-shaped hole 506, the second upper moving rod 504 is driven to move upwards, and further drives the second upper sleeve 9 to move upwards, so that the second upper connecting plate 2 moves upwards until the second upper connecting plate 2 moves upwards to the upper interval 13.

[0046] When one end of the lower drive rod 601 connected with the first lower moving rod 602 is pressed downwards, the first lower moving rod 602 is driven to move downwards, so that the first lower moving rod 602 drives the first lower sleeve 8 to move downwards and further drives the first lower moving plate 3 to move downwards, and at the same time, the first lower connecting rod 603 moves downwards along the lower strip-shaped hole 606, when the first lower connecting rod 603 moves to the bottom end in the lower strip-shaped hole, the second lower moving rod 604 is driven to move downwards, and further drives the second lower sleeve 10 to move downwards, so that the second lower moving plate 4 moves downwards until the second lower moving plate 4 moves downwards to the lower interval 14, the middle stationary contact group and the lower stationary contact are exposed, and the connection of the circuit is facilitated.

[0047] As a preferred embodiment, the upper driving rod 501 and the lower driving rod 601 are arranged in an X shape, and a pin shaft 12 is arranged at the intersection of the upper driving rod 501 and the lower driving rod 601. When the upper contact point group, the middle contact point group and the lower contact point need to be exposed, the upper driving rod 501 and the lower driving rod 601 are manually held at the middle part, and the upper driving rod 501 and the lower driving rod 601 are rotated along the pin shaft 12, so that the upper driving rod 501 connected with the first upper moving rod 502 is lifted upward, and the lower driving rod 601 connected with the first lower moving rod 602 is moved downward.

[0048] As a preferred embodiment, the second upper moving plate 2 comprises a first upper plate body 201 and a second upper plate body 202, the second upper sleeve 9 is connected with the second upper plate body 202, a second upper pin shaft 2021 is arranged on the second upper plate body 202, and a second pin shaft hole 2011 is correspondingly arranged on the first upper plate body 201, and the second upper pin shaft 2021 is matchedly arranged in the second pin shaft hole 2011.

[0050] In the present application, the second upper moving rod 504 moves upward, thereby driving the second upper sleeve 9 to move upward, realizing the upward movement of the second upper plate body 202 along the first upper plate body 201. The arrangement of the second upper pin shaft 2021 and the second pin shaft hole 2011 realizes the more stable upward movement of the second upper plate body 202 along the first upper plate body 201, and finally realizes the stacking of the second upper plate body 202 at the bottom end of the first upper plate body 201. With the continuous upward movement of the second upper moving rod 504, the second upper plate body 202 drives the first upper plate body 201 to continue to move upward, until the stacked second upper plate body 202 and the first upper plate body 201 move to the upper interval 13 position, completing the movement of the second upper moving plate 2. The stacked second upper plate body 202 and the first upper plate body 201 reduce the overall width of the second upper moving plate 2, and finally realize the matching of the small upper interval of the second upper moving plate 2, thereby reducing the volume of the protection mechanism. Similarly, with the downward movement of the second lower moving rod 604, the second lower sleeve 10 moves downward, realizing the downward movement of the first lower plate body 401. The arrangement of the first upper pin shaft 4011 and the first pin shaft hole 4021 facilitates the guiding effect of the first lower plate body 401, ensuring the stability of the downward movement of the first lower plate body 401. When the first lower plate body 401 is stacked to the bottom end of the second lower plate body 402, with the continuous downward movement of the second lower moving rod 604, the first lower plate body 401 drives the second lower plate body 402 to move downward until the stacked first lower plate body 401 and the second lower plate body 402 move to the lower interval 14, completing the movement of the second lower moving plate 4, and making the middle static contact group completely exposed, facilitating the circuit connection. The stacked first lower plate body 401 and the second lower plate body 402 reduce the width of the second lower moving plate 4, facilitating the matching of the smaller width of the lower interval 14, and thereby realizing the purpose of reducing the volume of the protection mechanism.

[0051] The first upper plate body 201 is further provided with a first upper guide groove 2012, and the second upper plate body 202 is provided with a first lower guide groove 2022.
