The invention relates to the technical field of three-dimensional scanners, and discloses a tracking laser three-dimensional scanner, which includes a mounting plate, the bottom surface of the mounting plate is movably installed with foot rods, the number of the foot rods is three, and three The inner surfaces of the foot rods are all fixedly connected with connecting rods, and the top surface of the connecting rods is provided with an inner groove, and a supporting rod is movably sleeved inside the inner groove, and casters are fixedly installed on the bottom surface of the supporting rods. The tracking laser three-dimensional scanner fixedly installs the connecting rod on the inner surface of the foot rod, and opens an inner groove on the top surface of the connecting rod, and uses the short axis in the inner groove to socket the supporting rod, so that the supporting rod has the effect of rotation , install casters on the bottom surface of the support rod, when it is necessary to move, rotate and lock the support rod, so that the casters on the bottom surface of the support rod touch the ground, realize the movement of the device, improve the convenience of device movement, and avoid manual lifting of the device for moving, Reduce labor expenditure, easy to use.
