[0018] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] Please refer to Figure 1-4An electrostatic discharge device comprises a wire-holding static contact 1 and a wire-holding moving contact 2. The wire-holding static contact 1 is set in a U shape, and the wire-holding moving contact 2 is arranged in the wire-holding static contact 1. A rotating shaft 4 is provided below the wire-holding static contact 1. The rotation of the rotating shaft 4 drives the wire-holding moving contact 2 to rise and fall in the wire-holding static contact 1. The wire-holding moving contact 2 moves upward to clamp the discharge conductor 8 in the wire-holding static contact 1. A grounding wire 6 is provided on the outside of the wire-holding static contact 1.

[0020] Specifically, the rotating shaft 4 passes through the bottom of the wire-clamping static contact 1 and is rotatably connected to the wire-clamping moving contact 2 through a threaded fit, wherein the top of the rotating shaft 4 rotates in cooperation with the wire-clamping moving contact 2 through a bearing, and a spring 5 is provided between the bottom of the wire-clamping moving contact 2 and the wire-clamping static contact 1, one end of the spring 5 is fixed to the bottom surface of the wire-clamping moving contact, and the other end is fixed to the wire-clamping static contact; in addition, a notch 21 is provided on one side of the wire-clamping moving contact 2, and the wire-clamping moving contact 2 engages with the vertical wall of the wire-clamping static contact 1 through the notch 21.

[0021] When using electrostatic discharge, such as Figure 3 As shown, firstly, the rotating shaft 4 is rotated to move the wire clamping movable contact 2 downward to leave space for clamping the discharge conductor 8. When the discharge conductor 8 enters between the wire clamping movable contact 2 and the wire clamping stationary contact 1, the rotating shaft 4 is rotated in the opposite direction again; Figure 4 As shown, the rotating shaft 4 is rotated in the opposite direction to move the wire-holding movable contact 2 upward. As the wire-holding movable contact 2 moves upward, the discharge conductor 8 can be pressed against the inner top surface of the wire-holding static contact 1. At this time, the discharge conductor 8 contacts the wire-holding static contact 1 and the wire-holding movable contact 2 at the same time, and the static electricity is finally released through the grounding wire 6. The overall structure is stable, easy to manufacture on site, and highly practical.

[0022] In this embodiment, the wire-holding static contact 1 and the wire-holding moving contact 2 are both made of aluminum and can release static electricity.

[0023] As a preferred solution, one end of the grounding wire 6 is connected to the outer wall of the wire-locking static contact 1 through a locking bolt 7, and the other end of the grounding wire 7 contacts the ground. When in use, the grounding wire releases static electricity to the ground.

[0024] Based on the above embodiment, an operating rod 9 is further provided below the rotating shaft 4, and the operating rod 9 is coaxially fixedly connected to the rotating shaft 4. The rotation of the operating rod 9 drives the discharge conductor to rise and fall. Since the high-voltage line is relatively high and the rotating shaft 4 is too short to meet the use requirements, the establishment of the operating rod 9 can increase the working height and expand the scope of application.

[0025] In order to increase the biting force of the wire-holding static contact 1 and the wire-holding moving contact 2, biting teeth 3 are provided on the inner top surface of the wire-holding static contact 1 and the upper surface of the wire-holding moving contact 2. The discharge conductor 8 is clamped between the upper and lower biting teeth 3. After biting, the friction and biting force can be increased to prevent it from falling off when static electricity is released.

[0026] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
