The utility model has the advantages that:
1. when the nut with the hexagonal head is rotated, the initial lever is collided to lift the screw rod upwards, so that the collet chuck is loosened. When the reverse nut moves upwards, the disk spring forces the collet to move downwards through the screw rod to clamp a workpiece, so that the fixing time can be greatly reduced when the piston rod is replaced.
2. The butterfly spring is arranged inside the clamp, so that damage to the piston rod due to over-fastening of the clamp can be effectively reduced, and unnecessary damage to the piston rod is brought.
