The embodiment of the invention discloses an adjustable depth-of-field device of a mold monitor. The rotary lens comprises: a holding member, a rotating member, a lens member, a sensor, and a pcb. Therotating part is embedded in the holding part and is used for providing a rotating fulcrum for rotation of the rotating part; the sensor is in circuit connection with the pcb through a copper column;the bearing is arranged on the inner side of the holding part; the camera module is used for receiving an image formed by a lens component. Wherein the lens component and the rotating component are connected through threads, and the rotating component performs spherical-to-spherical movement around the sphere center of the holding component along with rotation of the rotating component, so that an image surface shot by the lens component is always received by the sensor in a parallel mode. The operation structure is stable and reliable, the maintaining part and the rotating part are fully arranged in the same sphere c
