Abstract:
A locking device has a collar body, a roller cage, multiple rollers, and a clamping set. The collar body has a chamber formed inside the collar body and multiple concave recesses formed in an inner periphery of the collar body. The roller cage is mounted in the chamber. The clamping set has multiple clamping blocks annularly disposed within the roller cage. Each one of the multiple clamping blocks is curved and has multiple second concave recesses formed in an outer peripheral surface of the clamping block. The multiple rollers are rotatably mounted to the roller cage and are respectively received by the multiple first concave recesses and the multiple second concave recesses. Each one of the multiple rollers is rotatable along a corresponding one of the multiple first concave recesses and a corresponding one of the multiple second concave recesses.

Claim (Index 1):
A locking device comprising:\n a collar body having\n two faces facing to opposite directions; \n an inner periphery; \n a mounting opening defined in one of the two faces of the collar body; \n an inserting opening defined in the other one of the two faces of the collar body and coaxially aligned with the mounting opening; \n a chamber formed inside the collar body and communicating with the mounting opening and the inserting opening; and \n multiple first concave recesses formed in the inner periphery of the collar body and making the mounting opening have a corrugated outline; \n a roller cage mounted in the chamber and having multiple slots respectively aligned with the multiple first concave recesses; each one of the multiple slots having a notch disposed toward the mounting opening; and multiple rollers respectively and rotatably mounted in the multiple slots and respectively abutting the multiple first concave recesses; a clamping set mounted in the chamber and within the roller cage; the clamping set having\n multiple clamping blocks annularly disposed within the roller cage; \n each one of the multiple clamping blocks being curved and having\n an outer peripheral surface facing to the inner periphery of the collar body; and \n multiple second concave recesses formed in the outer peripheral surface; \n multiple second concave recesses of the multiple clamping blocks respectively abutting the multiple rollers and making each one of the multiple rollers rotatable along a corresponding one of the multiple first concave recesses and a corresponding one of the multiple second concave recesses; and \n \n a blocking plate fastened to the collar body to retain the roller cage, the multiple rollers, and the clamping set inside the collar body; the blocking plate having a surface abutting against the collar body, the roller cage, the multiple rollers, and the multiple clamping blocks.
