[0033] Specifically as follows, first, the tool is placed on the left end of the circular ring table 5, and the hole on the tool is inserted outside the support plate 807. Because before placing the tool, the two rotating plates 803 will move to the center under the pull of the connecting spring 804, and the distance between the two support plates 807 is reduced through the connecting rod 805, so that the hole on the tool is easily inserted outside the support plate 807, improving the convenience when placing. Then the motor 2 drives the circular ring table 5 to rotate through the rotating shaft 3 and the connecting cover 4, and the ball bearing 6 can reduce the friction between the circular ring table 5 and the base 1. The circular ring table 5 also drives the roller seat 702 to move on the convex ring 701 through the buffer spring seat one 703, and when it moves to the right end of the convex ring 701, the pull rod 704 drives the pressing plate 705 to move downward under the limiting of the limiting frame 706, thereby automatically clamping and positioning the tool. At the same time, the buffer spring seat one 703 and the buffer spring seat two 708 will make the tool have a certain buffer distance when machining, avoiding the tool from breaking due to excessive stress. When the pressing plate 705 is pressed tightly against the tool, the tool will extrude the limiting seat 806, and the elastic coefficient of the supporting spring 801 is greater than that of the connecting spring 804, so that the rotating plate 803 rotates on the sliding plate 802, and the support plate 807 moves to the both sides, thereby supporting and limiting the hole of the tool, improving the stability when clamping. Under the action of the supporting spring 801 and the connecting spring 804, the hole diameter of the support plate 807 can also be increased to adapt to different tools, thereby improving the adaptation range of the positioning tool. In addition, the pressing plate 705 also drives the limiting block 902 to move downward, so that it contacts with the pulley seat 904, thereby pushing the sliding rod 903 to drive the limiting plate 906 to limit one end of the tool, avoiding the tool from rotating during machining, and further improving the stability when clamping. Because the limiting plates 906 at both ends move synchronously, the tool can be centered, which makes it unnecessary to align the tool too accurately when placing, thereby improving the efficiency when placing and the accuracy when machining. In addition, the limiting plate 906 can rotate on the sliding rod 903, thereby being able to fit the side surface of the tool with different inclinations, further improving the adaptation range of the positioning tool. Moreover, the limiting spring seat 901 can also buffer between the limiting block 902 and the pressing plate 705, thereby avoiding excessive stress on the tool. After the roller seat 702 returns to the left end of the convex ring 701, the stretching spring 707 pulls the pressing plate 705, which can automatically loosen the tool, thereby improving the efficiency when clamping the tool. In addition, when machining the tool on the right end of the supporting plate 709, it is convenient to take and place the tool on the left end of the supporting plate 709, thereby improving the efficiency when machining multiple tools.
