The invention provides small stone carving laser carving equipment. The small stone carving laser carving equipment comprises a base, a supporting beam arranged on the base, a clamping mechanism usedfor clamping a cylindrical stone, an air cylinder, a longitudinal axis sliding rail, a horizontal axis sliding rail, a spindle motor, and a carving knife head connected with the spindle motor, whereinthe air cylinder is arranged on the supporting beam, and the air cylinder, the longitudinal axis sliding rail, the horizontal axis sliding rail and the spindle motor are connected with one another insequence; and the clamping mechanism comprises a semicircular supporting groove, a fixed seat, a concave movable seat, two corresponding clamping blocks and a hydraulic cylinder, and the semicircularsupporting groove is used for containing the cylindrical stone. The small stone carving laser carving equipment is characterized in that the cylindrical stone is placed in the semicircular supportinggroove, the hydraulic cylinder is used for driving the movable seat and a wedge-shaped block to move downwards, and when the wedge-shaped block makes contact with the wedge-shaped surface, the two clamping blocks are driven to move oppositely, and two rubber pieces on the semicircular supporting groove tightly wrap the cylindrical stone, so that the cylindrical stone does not move in the carvingprocess, and the carving accuracy of the cylindrical stone is greatly improved.
