The positioning device is provided with a receiving groove A1 on the side of the through hole A0 of the base A, and the positioning rod group B is provided by the through hole A0. The positioning rod B1 is disposed, and the positioning rod B1 is provided with a wearing body B11, and the outer edge of the positioning rod B1 of the wearing body B11 is convexly provided with a stopping ring B12, and is stopped by the stopping ring B12 to the other side. The sliding rod body B13 is extended, and the outer edge of the sliding rod body B13 is axially cut with two opposite long cutting edges B14, that is, the middle portion of the sliding rod body B13 is provided with a concave ring groove B15, and The other side of the sliding rod body B13 is provided with an inner screw hole B16, and the elastic body B2 is disposed on the sliding rod body B13 so that the elastic body B2 side abuts against the stopping ring B12 of the positioning rod B1. The other side of the elastic body B2 is abutted against the side of the limiting body B3, and the limiting body B3 is fixed in the receiving groove A1 of the base A, and a rectangular groove-shaped limit is arranged inside the limiting body B3. hole B30, the inner side of the limiting hole B30 has two opposite shrinking side edges B31, and the two sliding sides B13 of the sliding rod body B13 of the positioning rod B1 can be moved and displaced by the two contraction side edges B31 of the position limiting body B3. Sliding The inner screw hole B16 on the side of the moving rod body B13 is locked by the screw B41 on the side of the head B4, so that the head B4 is exposed outside the base A, and the positioning rod B1 can be pulled to the through hole A0 by the head B4. The internal contraction causes the positioning rod B1 side of the wearing body B11 to contract into the through hole A0, and the stopping ring B12 pushes the elastic body B2 to the limiting body B3 for compression, so that the sliding rod body B13 is in the limiting body B3. When the concave ring groove B15 is in the position of the position limiting body B3, the rotating head B4 can rotate the positioning rod B1, and the sliding side of the sliding rod body B13 is turned to the limit B14. The two side contraction side edges B31 of the body B3 are staggered and staggered to hold the sliding rod body B13 at the limiting body B3; and the head B4 can be rotated to drive the sliding rod body B13 to rotate.
