Patent ID: 7874378

Claim:
A vibratory and impact connector for a power tool being connecting to a power tool and a work head, comprising: an outer cylinder defined in its bottom with a through hole and defined on its outer surface with a ring of protruding teeth; a sleeve provided on its inner surface with teeth for meshing with the protruding teeth of the outer cylinder and mounted on an outer periphery of the outer cylinder; a spring received in the outer cylinder; a first drive rod received in the outer cylinder in such a manner that one end of the first drive rod is inserted through the spring and extended out of the through hole of the outer cylinder to connect the work head, the other end of the first drive rod is defined with a plurality of protruding tapering teeth and an inserting hole, the teeth of the first drive rod being spaced apart and annularly arranged around the inserting hole, each of the teeth including a top surface and two oblique surfaces, each top surface being axially defined with a slot for holding rolling balls, and between each two neighboring teeth of the first drive rod being formed a connecting surface; a drive ring received in the outer cylinder and defined with a central circular hole and a plurality of protruding and tapering teeth annularly arranged around the circular hole, each of the teeth of the drive ring including a top surface and two oblique surfaces, and between each two neighboring teeth of the drive ring being formed a connecting surface, the teeth of the drive ring being engaged with the teeth of the drive rod in such a manner that the rolling balls of the first drive rod are abutted against the connecting surfaces among the teeth of the drive ring; and a second drive rod having one end inserted through the circular hole of the drive ring and into the inserting hole of the first drive rod and having the other end of the second drive rod connected with the power tool, the second drive rod driving the first drive rod to rotate, the teeth of the driving ring engaging with the teeth of the outer cylinder, restricting the sleeve, the outer cylinder and the drive ring from rotation, making the rolling balls of the first drive rod press against the connecting surfaces among the teeth of the drive ring or the top surfaces of the teeth of the drive ring, so that the teeth of the drive ring are caused to engage with or disengage from the teeth of the first drive rod, and consequently, the work head connected to the first drive rod is caused to perform impact operation.
