[0046] An elastic element 300, the elastic element 300 is sleeved on the linear moving mechanism, and one end of the elastic element 300 is fixedly connected to the linear moving mechanism;

[0047] A connecting plate 400, the connecting plate 400 is connected to the other end of the elastic element 300;

[0048] The linear moving mechanism passes through the connecting plate 400;

[0049] A driving assembly, the driving assembly is mounted on the frame, and the driving assembly is connected to the linear moving mechanism;

[0050] The driving assembly is suitable for driving the connecting plate 400 to move vertically by driving the linear moving mechanism;

[0051] A connecting block 500, wherein the connecting block 500 is mounted on the connecting plate 400;

[0052] The connection block 500 is adapted to be driven by the connection plate 400 to move vertically so as to contact and connect the input block 210 and the output block 220 .

[0053] In this embodiment, if Figure 1 As shown, first, the linear moving mechanism can be driven by the driving component to move vertically on the frame 100, thereby driving the connecting plate 400 and the connecting block 500 on the connecting plate 400 to move vertically. Among them, the connecting block 500 can be connected or disconnected with the input block 210 and the output block 220 through this vertical movement, so as to realize the electrical connection or disconnection between the input block 210 and the output block 220. Further, in combination with the elastic element 300 and the linear moving mechanism, the contact pressure between the connecting block 500 and the input block 210 and the output block 220 can be adjusted more accurately, thereby ensuring the contact stability when a large current passes through, and preventing equipment failure caused by unstable contact. The safety hazard caused by unstable contact connection is substantially solved. The elastic element 300 can be a compression spring, and the material can be a non-magnetic material.

[0054] Specifically, Figure 1-3 As shown, the linear motion mechanism can be structured as follows:

[0055] A lead screw, the lead screw is vertically rotatably mounted on the frame 100;

[0056] A nut, which is rotatably mounted on the lead screw;

[0057] Auxiliary guide rods, at least one auxiliary guide rod is vertically mounted on the frame 100;

[0058] The connecting plate 400 is slidably mounted on the auxiliary guide rod, and the connecting plate 400 is fixedly connected with the nut;

[0060] In this embodiment, if Figure 1-3 As shown, the two ends of the lead screw are rotatably connected to the frame 100 through bearings and other mechanisms. The nut is rotatably mounted on the lead screw and can move along the thread direction of the lead screw. At least one auxiliary guide rod is vertically mounted inside the frame 100, and the auxiliary guide rod is arranged parallel to the lead screw. The connecting plate 400 is slidably mounted on the auxiliary guide rod through mechanisms such as slide grooves, so that it can slide along the direction of the auxiliary guide rod. The lower part of the connecting plate 400 is fixedly connected to the nut. When the nut rotates and moves on the lead screw, it drives the connecting plate 400 to move vertically on the auxiliary guide rod. Through the transmission of the lead screw and the nut, the vertical movement position of the connecting plate 400 can be accurately controlled. The auxiliary guide rod and the connecting plate 400 are slidably matched to ensure that the connecting plate 400 moves accurately and stably in the vertical direction. The linear moving mechanism has a simple and reliable structure, which enables the connecting plate 400 to achieve precise vertical movement. In actual use, the lead screw can be driven to rotate by the motor, thereby driving the nut and the connecting plate 400 to move, realizing the vertical positioning of the connecting block 500, and completing the on and off operation of the switch.

In this way, a reliable electrical connection with an external circuit can be achieved through the connecting copper bar 230 and the connecting hole. The external circuit can effectively transfer electrical energy to the input block 210 and the output block 220 through the connecting copper bar 230. The connecting copper bar 230 and the connecting hole are simply arranged, which is convenient for the access of the external circuit.
