It also includes a sleeve 400, and a side rod 301 is arranged on the rotating shaft 300. The inner wall of the sleeve 400 is provided with a side groove 401, and the side rod 301 is embedded in the side groove 401. A side column 402 is arranged on the side of the sleeve 400, and the side column 402 is connected with a stirring shaft 500.
[0026] The shaft sleeve 400 is sleeved on the rotating shaft 300 , and the two are rotated synchronously through the connection structure of the side rod 301 and the side groove 401 .

[0028] A first conductive arc piece 403 a and a second conductive arc piece 403 b are disposed at the bottom of the threaded hole 403 , and the first conductive arc piece 403 a and the second conductive arc piece 403 b are stacked in the center.
[0029] Furthermore, the central angles of the first conductive arc piece 403a and the second conductive arc piece 403b are both 90°.
[0030] The first conductive arc piece 403a and the second conductive arc piece 403b are connected to an external circuit via a wire disposed in the sleeve 400. Specifically, the external circuit includes a switch and a power supply. A slip ring can be disposed in the sleeve 400 to maintain a stable connection of the circuit in a rotating state. This is a prior art and will not be described in detail.
