[0023] Universal ball structure 23 includes ball joint 231 and ball shell 232, ball joint 231 is installed in ball shell 232 and can rotate in ball shell 232, grounding head 22 is threadedly connected with ball joint 231.

[0024] Wherein, ball shell 232 includes threadedly connected upper half ball shell and lower half ball shell, after placing ball joint 231 between upper half ball shell and lower half ball shell, threadedly connecting upper half ball shell and lower half ball shell, ball joint 231 is installed in ball shell 232.

[0025] Magnetic attraction seat 21 is provided with a collar seat 211, a sliding groove is formed on the inner wall of the collar seat 211, a clamping block is arranged on the outer wall of the ball shell 232, the ball shell 232 is sleeved in the collar seat 211, and the clamping block is embedded in the sliding groove, and a ring cover 212 is threadedly connected on the collar seat 211 to close the sliding groove and prevent the ball shell 232 from sliding out.

[0026] Universal ball structure 23 and magnetic attraction seat 21 are provided with a compression spring 24; specifically, the compression spring 24 is arranged between the ball shell 232 and the ring cover 212.

[0027] The grounding head 22 is provided with a restoring spring 25 between the grounding head 22 and the spherical shell 232.

[0028] The magnetic attraction base 21 comprises a shell 213 made of insulating material, and a ring-shaped magnet 214 is fixed in the shell 213.

[0029] The grounding head 22 is provided with a wire mounting groove 221, and one end of the wire is mounted in the wire mounting groove 221.

[0030] Specifically, the shell 213 is in the shape of a circular cover, the ring-shaped magnet 214 is glued to the inner wall of the shell 213 and the end face is flush with or protrudes from the end face of the opening end of the shell 213, so as to be attracted to the grounding flat iron; the sleeve ring seat 211 is located in the ring-shaped magnet 214, and a through hole is formed in the shell 213 and penetrates into the sleeve ring seat 211, which is used for penetrating the wire to connect with the grounding head 22; the compression spring 24 pushes the universal ball structure 23 towards the opening end of the shell 213, and makes the grounding head 22 protrude from the ring-shaped magnet 214, so as to ensure that the grounding head 22 can be attached to the grounding flat iron when the ring-shaped magnet 214 is attracted to the grounding flat iron.

[0031] It is worth mentioning that the connection end 1 is connected to the equipment in a conductive manner by means of bolts or threads, or by using the connecting head, plug and the like in the prior art.

[0032] In specific implementation, the connection end 1 is connected to the equipment to be grounded, and the magnetic attraction end 2 is attracted to the grounding flat iron, so that the grounding of the equipment to be grounded is completed. When the magnetic attraction end 2 is attracted, the ring-shaped magnet 214 is magnetically attracted to the grounding flat iron, the grounding head 22 is in contact with the grounding flat iron and rotates around the universal ball structure 23 to be attached to the grounding flat iron as much as possible, and at the same time, the universal ball structure 23 is pressed to slide in the sleeve ring seat 211, the compression spring 24 is contracted, and the elastic force generated by the compression spring 24 also acts on the grounding head 22 through the universal ball structure 23, so that the grounding head 22 is attached to the grounding flat iron. When the mobile equipment is moved, the magnetic attraction end 2 is pulled out by external force, so that the ring-shaped magnet 214 is not attracted to the grounding flat iron. After the magnetic attraction end 2 is pulled out, the restoring spring 25 pushes the grounding head 22 to rotate around the universal ball structure 23 to keep coaxial with the restoring spring 25, so that the end face of the grounding head 22 is more easily aligned and attached to the grounding flat iron next time. At the same time, when the grounding device is not used, the restoring spring 25 makes the grounding head 22 not easily rotate around the universal ball structure 23 due to inertia generated by movement, reduces the distortion of the wire near the wire mounting groove 221 caused by the rotation of the grounding head 22, and avoids damage of the wire caused by metal fatigue.

[0033] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and cannot be understood as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
