Hole-forming positioning device for bored pile

The utility model discloses a drilling pile hole-forming positioning device which comprises a positioning frame, limiting plates are installed on the two sides in the positioning frame, the limiting plates are in an arc shape and used for clamping a drilling pile and limiting the drilling pile, a plurality of rolling balls are movably installed on the inner sides of the limiting plates, and the rolling balls are used for enabling the two sides of the lower end of the positioning frame to be rotationally connected with T-shaped plates through pin shafts. The positioning frame is provided with a plurality of T-shaped plates, the T-shaped plates are assembled into a cross to be used for positioning the drilling position, magnets are installed on the sides, close to the middle of the interior of the positioning frame, of the T-shaped plates, and the two T-shaped plates are magnetically connected through the magnets. And friction borne by the bored pile after limiting can be reduced, rotation and descending of the
