[0016] As one technical solution, the height of the second annular protrusion is greater than the depth of the second annular groove; or, the wall thickness of the second annular protrusion is greater than the groove width of the second annular groove.

[0017] Specifically, by designing the height of the second annular protrusion to be greater than the depth of the second annular groove, the top of the second annular protrusion can press against the bottom of the second annular groove, thereby effectively improving the sealing and waterproofing effect. By designing the wall thickness of the second annular protrusion to be greater than the groove width of the second annular groove, the sidewall of the second annular protrusion can press against the groove wall of the second annular groove, thereby effectively improving the sealing and waterproofing effect.

[0018] As a technical solution, the sealing sleeve further includes a buffer groove, which is disposed on the side of the second mounting portion near the outer end, and the buffer groove is located at the connection between the second mounting portion and the surrounding portion.

[0019] Specifically, by setting up the buffer tank, a small amount of water can be collected and temporarily stored, preventing water from scattering everywhere and helping to improve the waterproof effect.

[0020] As a technical solution, the rocker control device further includes a first bolt and a second bolt. The outer extension is provided with a first through hole, and the end of the rocker near the sealing sleeve is provided with a first fixing hole.
