Because the gear assembly 22 is sleeved on the first gear 221, the gear assembly 22 can rotate relative to the second rotating shaft 42, so that the gear assembly 22 is rotatably connected with the base 40.

After the first gear 221 rotates, the first gear 221 drives the transmission gear 21 to rotate, so that the transmission gear 21 can drive the lens barrel assembly 10 to rotate, so that the lens barrel assembly 10 can extend or retract.

When the first projection 2221 of the second gear 222 is disengaged from the first groove 2211 of the first gear 221, the first gear 221 may be separated from the second gear 222, and when the second gear 222 rotates, the first projection 2221 of the second gear 222 cannot apply a force to the first groove 2211 of the first gear 221, so that the first gear 221 cannot rotate with the rotation of the second gear 222.
Since the second boss on the first gear 221 and the second groove on the second gear 222 form the second clutch structure, when the second boss on the first gear 221 is embedded in the second groove on the second gear 222, at this time, the first gear 221 and the second gear 222 can be connected, and when the second gear 222 rotates, the groove wall of the second groove on the second gear 222 can apply force to the second boss, so that the first gear 221 rotates along with the rotation of the second gear 222. When the second boss on the first gear 221 is separated from the second groove on the second gear 222, at this time, the first gear 221 and the second gear 222 can be separated, and when the second gear 222 rotates, the groove wall of the second groove on the second gear 222 cannot apply force to the second boss, so that the first gear 221 cannot rotate along with the rotation of the second gear 222.
It should be noted that the number of the first grooves 2211 may be set according to actual needs, and the number of the first bosses 2221 is equal to the number of the first grooves 2211, for example, the number of the first grooves 2211 may be 5, and the number of the first grooves 2211 is not limited herein in this embodiment of the application.

Specifically, under the condition that the lens barrel assembly is not subjected to an external force, the elastic member 23 may provide an elastic force to the first gear 221 or the second gear 222, so that the first boss 2221 on the second gear 222 may be tightly embedded into the first groove 2211 on the first gear 221, and further, the first gear 221 and the second gear 222 are tightly connected, and the first clutch structure is engaged. Or, the second boss on the first gear 221 can be tightly embedded into the second groove on the second gear 222, so that the first gear 221 and the second gear 222 are tightly connected, and the second clutch structure is engaged. When the lens barrel assembly 10 is contracted by an external force, the external force overcomes the elastic force of the elastic member 23, so that the first boss 2221 is disengaged from the first groove 2211, the first clutch structure is disengaged, and the first gear 221 is disengaged from the second gear 222; alternatively, the external force overcomes the elastic force of the elastic member 23, so that the second boss is disengaged from the second groove, the second clutch structure is disengaged, and the first gear 221 is disengaged from the second gear 222.
