The length of the supporting base 225 is greater than that of the through opening 204, so that when the supporting base 225 moves to the annular frame 202, the limiting extension 227 abuts against the annular frame 202, thereby preventing the supporting base 225 from moving outwards continuously, i.e. preventing the lens module 10 from moving outwards linearly.
It is understood that the limit of the supporting seat 225 is not limited to the annular frame 202, for example, a stop facing the supporting seat 225 may be separately provided on the back-collecting shell 200.

It will be appreciated that the threaded segment 233 is initially not threadedly engaged with the second threaded bore 338, which may be due to the axial spacing between the threaded segment 233 and the second threaded bore 338, i.e., the threaded segment 233 is not inserted into the second threaded bore 338 and is therefore not threadedly engaged; it is also possible that the threaded section 233 is inserted into the second threaded hole 338, but the second threaded hole 338 is provided with threads that engage with the threaded section 233 only in the middle or lower portion, and thus does not form a threaded engagement.
Referring to fig. 3 and fig. 7, as an improved manner of the present embodiment, the gear set 232 includes a first gear 234 fixed to the screw 231 and a second gear 235 engaged with the first gear 234, a first position-limiting portion 236 for preventing the second gear 235 from rotating relative to the lens module 10 is disposed at an end of the second gear 235 close to the lens module 10, and the lens module 10 is disposed with a second position-limiting portion 11 engaged with the first position-limiting portion 236.
In this embodiment, the supporting seat 225 is provided with receiving holes for the first gear 234 and the second gear 235, and the first gear 234 and the second gear 235 are mounted in the receiving holes, so that the risk of damaging the first gear 234 and the second gear 235 can be reduced.
