[0022] Embodiment 2

[0023] See also Figure 2 , Figure 3 and Figure 4On the basis of the first embodiment, in order to further realize the cleaning of the power component 22, the top and bottom of the inner wall of the placement groove 4 are respectively provided with a top groove 6 and a fan-shaped groove 5, the outer walls of the two sides of the cleaning block 9 are respectively slidably connected with the inner walls of the two sides of the placement groove 4, and a circular groove is provided at the top of the main body block 2. A spring 10 is fixedly connected inside the circular groove, and one end of the spring 10 is fixedly connected to the top of the inner wall of the top groove 6. A connecting rod 15 is rotatably connected between the inner walls of the two sides of the fan-shaped groove 5. The outer wall of the connecting rod 15 is fixedly connected with a cam 14.
