Positioning sleeve frame structure for improving positioning precision of embedded anchor bolt

The positioning sleeve frame structure comprises a top plate, two sides of the top plate are respectively provided with a group of side grooves, the interiors of the side grooves are movably connected with a positioning support frame, the top end of the top plate is provided with a positioning groove, and the bottom end of the positioning support frame is provided with a through hole. According to the positioning sleeve frame structure for improving the positioning precision of the embedded anchor bolt, the positioning groove is formed, before installation, the first positioning nut is rotated to be separated from the top end of the connecting plate, then the arc-shaped positioning plates at the two ends can be pulled to drive the connecting plate to move, and the arc-shaped positioning plates are moved to proper positions according to the diameter of the anchor bolt; and then the first positioning nut is rotated to be tightly attached to the top end of the connecting plate, so that the arc-shaped positioning
