Hole anchor
A hole anchor has a plug. An anchor shaft and a cord respectively pass through a center and a periphery of the plug. A top end and a bottom end of the anchor shaft respectively have a head and an annular structure. A spring is disposed between the annular structure and the plug. Two side rods of an anchor head assembly are juxtaposed respectively on a left side and a right side of the head. Two sides of each of the side rods respectively have a closed end and an open end. The two closed ends are engaged with each other via a concave-convex structure. A top side of each of the two open ends is pivotally connected to a pin connected to the cord. A pivot unit pivotally penetrates a middle of the two side rods and the head.
