The outer side of the slide rod 21 is fixedly connected to the mounting bracket 20. One side of the mounting bracket 20 is fixedly connected to the corresponding side of the fixed plate 10.

[0034] By starting the motor 29, it drives the elliptical plate 13 to rotate inside the through slot 30, and the rotating shaft 14 rotates inside the connecting frame 15, so that it drives the connecting frame 15 and slides on the upper side of the through slot 30, and at the same time drives the fixed plate 10 to move relatively, and starts the electric push rod 16, so that it pushes the rotating shaft 17 to rotate the rotating rod 18 on the front and rear sides of the rotating shaft 17, and at the same time the other side rotates inside the rotating seat 19, so that it drives the sliding plate 22 to slide on the outside of the sliding rod 21, and drives the curved plate 23 to move relatively to clamp and fix the impeller, so that it can clamp and fix impellers of different sizes, avoiding the impeller being driven out by the rotating force of the drill 28 when drilling the impeller.
