The outer diameter of the ring housing 20 of the present embodiment is 7 mm, but it is not excluded that the ring housing is configured to have a size of about 7 mm, such as 10 mm, 8 mm, or even 6 mm.

In this embodiment, the cover plate 40 includes a body 41 having a substantially disk shape and a protrusion 42 formed to protrude outward along an edge of the body 41. The two sides of the protrusion 42 connected to the body 41 are recessed inward to form a fitting groove 421. After the cover plate 40 is covered on the casing 20, the protrusion 42 is clamped into the notch 241, and simultaneously, the edge of the side wall 24 is clamped into the embedding groove 421, so that the side wall 24 is prevented from expanding outwards along the axis of the casing 20.

In this embodiment, a fixing structure that is engaged with each other is disposed between the side wall 24 and the cover plate 40, specifically, a hanging platform structure 43 is formed by the upper surface edge of the body 41 of the cover plate 40 being recessed downward at a position other than the protrusion 42, and a hook structure 242 is formed at a position corresponding to the upper edge of the side wall 24 of the housing 20. After the cover plate 40 is covered on the housing 20, the hook structure 242 is correspondingly buckled above the hanging platform structure 43 to limit the upward separation of the cover plate 40 from the housing 20. Specifically, after the cover plate 40 is covered on the housing 20, the hooking structure 242 is formed by pressing an outer side of the upper edge of the sidewall 24 from top to bottom by a mold core 50 (shown in fig. 4).
