In the process of zooming by using the electronic device, the field-induced deformation guide rail 400 is switched to a guiding state, the lens 200 is driven by the driving mechanism 300 to reciprocate on the field-induced deformation guide rail 400, thereby zooming is realized, when the user stops using the electronic device to zoom, the field-induced deformation guide rail 400 is switched to a limiting state, thereby enabling the lens 200 to be in limiting fit with the field-induced deformation guide rail 400, further enabling the lens 200 to be fixed on the device shell 100, when the user shakes the electronic device, because the lens 200 is relatively fixed with the device shell 100, the lens 200 cannot collide with other components in the electronic device, thereby prolonging the service life of the lens 200 and other components, and further prolonging the service life of the electronic device.
