Interactive projection lamp with lens capable of tracking movement

The utility model discloses an interactive projection lamp with a lens capable of tracking and moving, which relates to the technical field of projection lamps and comprises a mounting plate, a driving block is mounted on the mounting plate, and a projection lamp body is mounted on the driving block. When a projection lamp lens on a mounting plate is used for projection and a driving block moves, when a small semicircular plate moves on a large semicircular plate from the edge of the large semicircular plate to the top end of the large semicircular plate, the small semicircular plate drives a transmission rod to move, and the transmission rod drives a scraper to move towards the middle position of the projection lamp lens; and when the small semicircular plate moves towards the edge of the large semicircular plate, the two scraping plates are conveniently driven to move towards the two sides of the projection lamp lens again by utilizing the restoring force of the fiber springs, and dust on the projection lam
