Description

This application claims priority to Chinese Patent Application No. 202211058236.1, with the China National Intellectual Property Administration on August 30, 2022 and entitled "LENS CARRYING DEVICE, CAMERA MODULE, AND ELECTRONIC DEVICE". TECHNICAL FIELD Embodiments of this application relate to the field of terminal technologies, and in particular to a lens carrying device, a camera module, and an electronic device. BACKGROUND With explosive growth of electronic devices such as smartphones or tablet computers, the electronic device has more functions. Because people expect that the electronic device can meet more functional requirements, the electronic device can implement more functions. For example, people expect that camera performance of the electronic device is increasingly high, to obtain a high-resolution image. A camera module is disposed in the electronic device. The camera module includes a lens, a lens tube, and a photoelectric sensor. Light from the outside can reach the photoelectric sensor through the lens in the lens tube. The photoelectric sensor converts an optical signal into an electrical signal for forming an image. In conventional technologies, both the lens and the lens tube are fixed. Therefore, a range of a shooting angle of the camera module is fixed when an overall position of the electronic device is fixed. When the electronic device moves as a whole, the camera module moves synchronously. Consequently, the camera module has a poor scenario adaptation capability. EP 3 869 772 A1 discloses an imaging module, a camera assembly and an electronic apparatus. The imaging module comprises a housing, and a light reflection element, an image sensor, a lens assembly, a motion element and a drive mechanism which are all provided inside the housing. The imaging module further comprises a modular circuit board, wherein the modular circuit board is fixed on the housing; the modular circuit board comprises a reinforcement board; and the reinforcement board is in communication with a ground pin of the modular circuit board, such that the housing is connected to the ground. EP 4 013 031 A1 discloses a camera actuator, and camera module and camera device comprising same. EP 3 822 588 A1 discloses an optical-path folding-element with an extended two degree of freedom rotation range. SUMMARY Embodiments of this application provide a lens carrying device, a camera module, and an electronic device, to enable the camera module to adapt to more scenarios. A first aspect of this application provides a lens carrying device. The lens carrying device according to the present invention as defined in the independent claim 1, includes a base, a rotating support, a swinging support, a first flexible printed circuit board, and a second flexible printed circuit board. The base includes a first accommodation portion and a circuit board. The circuit board is located in the first accommodation portion. The rotating support is disposed in the first accommodation portion. The rotating support may be rotatably connected to the base. The rotating support rotates relative to the base around a first axis. The rotating support includes a second accommodation portion. The swinging support is disposed in the second accommodation portion. The swinging support may be rotatably connected to the rotating support. The swinging support rotates relative to the rotating support around a second axis. The swinging support includes a third accommodation portion. The first axis and the second axis are perpendicular to each other. The first flexible printed circuit board is disposed on the swinging support. The second flexible printed circuit board includes a first connection end and a second connection end. The first connection end is electrically connected to the first flexible printed circuit board. The second connection end is electrically connected to the circuit board. According to the lens carrying device in this embodiment of this application, rotations of the rotating support and the swinging support are controlled separately, so that an angle of the lens can be adjusted. The rotating support drives the swinging support to rotate around the first axis. The swinging support may rotate around the second axis. When positions of the rotating support and the swinging support are changed, a position of a light entry region of the lens is changed, to enable a camera module having the lens carrying device to obtain a relatively large field of view. Therefore, when the electronic device does not move as a whole, the camera module can continuously perform, by adjusting the angle of the lens, shooting at different angles, to splice the image with the large field of view or perform following shooting, and enable the camera module to adapt to more scenarios. In a possible implementation, the first flexible printed circuit board includes a body portion. The body portion is located on a side, facing the base, of the swinging support. The circui
