Triangular auxiliary support of laser tracker

The utility model discloses a triangular auxiliary support for a laser tracker, which relates to the technical field of mounting supports for laser trackers and comprises a support body, a main rod and three mounting seats fixedly connected onto the main rod, and a support leg is hinged in each mounting seat. The movable ring slides on the main rod, then the movable ring is limited through the fixing bolts and the limiting screw holes, under the action of the hinge rods, the supporting legs can rotate in the mounting base, then the rotating angles of the three supporting legs in the mounting base are the same, the main rod can be stably fixed to the ground, and the supporting legs can be stably fixed to the ground. The height of the laser tracker on the ground can be adjusted by adjusting the rotation angle of the supporting legs in the mounting base, the supporting legs can be rotated to be perpendicular to the main rod through the hinge rods through the moving rings, the occupied space of the support body c
