By providing the first anti-overflow groove 237 at the periphery of the first welding portion 232 and providing the second anti-overflow groove 337 at the second welding portion 332, the excess material generated when the first welding portion 232 is welded to the second welding portion 332 can be contained in the first anti-overflow groove 237 and/or the second anti-overflow groove 337, so that the outer surface of the first lens base 203 can contact or attach to the outer surface of the second lens base 303, thereby reducing the distance between the outer surface of the first lens base 203 and the outer surface of the second lens base 303.

Further, referring to fig. 18 and fig. 19, a first clamping portion 238 is further disposed on the outer surface of the first lens base 203, and the first clamping portion 238 and the first welding portion 232 are disposed at an interval. The outer surface of the second lens base 303 is further provided with a second clamping portion 338, the second clamping portion 338 and the second welding portion 332 are arranged at intervals, and the first clamping portion 238 and the second clamping portion 338 are clamped together. Optionally, the combination of the first clamping portion 238 and the second clamping portion 338 includes, but is not limited to, a combination of a hook and a buckle, a combination of a protrusion and a groove, and the like. In other embodiments, the first clamping portion 238 and the second clamping portion 338 can be replaced by two magnetic pieces which are magnetically attracted.

By providing the first clip portion 238 on the first lens base 203 and the second clip portion 338 on the second lens base 303, the first clip portion 238 and the second clip portion 338 are engaged with each other, so that the first lens base 203 and the second lens base 203 can be relatively fixed when the first welding portion 232 and the second welding portion 332 are welded. In addition, the first clamping portion 238 and the second clamping portion 338 can be used for aligning the first lens base 203 and the second lens base 303 before the first welding portion 232 and the second welding portion 332 are welded.

The foregoing is a partial description of the present application, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present application, and these modifications and decorations are also regarded as the protection scope of the present application.
