[0025] In order to achieve the movement of the two support blocks 10 away from each other by adjusting the bidirectional screw rod 9, and then drive the two arc surface support rods 12 to move away from each other and gradually contact and expand and tighten with the inner wall of the nut member 14, at this time the initial tightening of the nut member 14 is completed, two support blocks 10 are slidably installed on the outer wall of one side of the connecting block 8, and the bidirectional screw rod 9 passes through the two support blocks 10 and is threadedly connected with the two support blocks 10, an avoidance hole 11 is opened on the outer wall of one side of the mounting block 2, and the arc surface support rods 12 are fixedly installed on the outer walls of one side of the two support blocks 10, and the two arc surface support rods 12 both pass through the avoidance hole 11 and are movably connected with the inner wall of the avoidance hole 11, and the two arc surface support rods 12 both pass through the avoidance hole 11 and are movably connected with the inner wall of the avoidance hole 11, and the two arc The two curved surfaces of the surface support rod 12 play the role of expanding and conveniently contacting and supporting the inner wall of the fixed screw hole after probing into the screw holes of different apertures. The two arc surfaces of the two arc surface support rods 12 are fixedly installed with a clamping block 13 at one end outside the mounting block 2. After the two clamping blocks 13 play the role of positioning and contacting the nut member 14, the nut member 14 is clamped on the side wall of the mounting block 2 by driving the output shaft of the micro cylinder 4 to contract.
