ABSTRACT:
A vibratory and impact connector for a power tool is provided with a spring, a first drive rod, a drive ring and a second drive rod which are sequentially received in an outer cylinder. The first drive rod is inserted through the spring and extended out of the outer cylinder, the second drive rod is inserted through the drive ring and into the first drive rod, and the drive ring is fixed to the outer cylinder. By such arrangements, driving the second drive rod can rotate the outer cylinder, the first drive rod and the drive ring. Furthermore, by restricting the rotation of the outer cylinder, the drive ring can also be restricted from rotation, and the drive ring and spring can cooperate with a spring to drive the first drive rod to perform axial reciprocation, thus creating an impact operation.
