a plurality of push rods coupled to the pop-up/down housing, and wherein the plurality of push rods and the camera module are fastened relative to each other; and
a driving source configured to drive the plurality of push rods to move synchronously in a direction parallel to the first direction, wherein the driving source and the fastened holder are fastened relative to each other, and wherein the plurality of push rods is coupled to the driving source and is arranged on both sides of the driving source.

2. The camera assembly according to claim 1 , wherein the guide structure comprises:
a guide shaft having an extension direction parallel to the first direction, wherein the guide shaft and the fastened holder are fastened relative to each other; and
a sliding sleeve configured to slide in the extension direction of the guide shaft, wherein the sliding sleeve is sleeved outside the guide shaft, and wherein the camera module and the sliding sleeve are fastened relative to each other.

3. The camera assembly according to claim 2 , further comprising ear seats disposed at locations on the fastened holder that are close to two end portions of the guide shaft, wherein the ear seats comprise insertion holes, wherein the guide shaft passes through the insertion holes and is fastened on the ear seats, and wherein the sliding sleeve is slidably disposed on a shaft section of the guide shaft and between the ear seats.

4. The camera assembly according to claim 1 , wherein the driving source comprises:
a drive motor;
a transmission screw rod comprising one end coupled to an output shaft of the drive motor, wherein an extension direction of the transmission screw rod is parallel to the first direction;
a traction member coupled to the plurality of push rods and configured to drive the plurality of push rods to move synchronously, wherein the traction member threadedly matches the transmission screw rod; and
a leading structure configured to guide the traction member to move along the transmission screw rod.

5. The camera assembly according to claim 1 , wherein the driving source is disposed close to a middle location at a bottom of the fastened holder, wherein one push rod of the plurality of push rods is disposed at each of two sides of the driving source, wherein a concave region is formed at a location on the pop-up/down housing and close to the driving source, wherein the driving source is configured to drive, using the plurality of push rods, the camera module to move between a pop-up location and a pop-down location, wherein the driving source is located in the concave region when the camera module is at the pop-down location, and wherein the driving source is separated from the concave region when the camera module is at the pop-up location.

6. The camera assembly according to claim 1 , wherein a cavity is formed in the fastened holder, wherein the driving source, the camera module, and the plurality of push rods are all disposed in the cavity, wherein the fastened holder further has a punch hole communicating with the cavity, and wherein the camera module is configured to extend to an outside of the cavity through the punch hole when moving relative to the fastened holder.

7. The camera assembly according to claim 1 , wherein each of the plurality of push rods is of an inverted T-shaped structure.

8. The camera assembly according to claim 1 , wherein a size of the camera module in a length direction is from 50 millimeter (mm) to 300 mm, and wherein the length direction of the camera module is a direction perpendicular to the first direction.

9. An electronic device, comprising:
