The utility model discloses a multi -functional rotatory chock, including gyro wheel, gyro wheel support and hollow shaft, the gyro wheel passes through the gyro wheel support to be fixed on the hollow shaft, the hollow shaft is located the seat cover, just the hollow shaft both ends are equipped with a self -aligning bearing respectively, the race of gyro wheel including the grooving that is used for wire rope to pass through, be used for key way, inclined plane and flange that the anchor chain passes through, install the anchor chain in the key way and erect the horizontal chain link of chain ring sum anchor chain, the longitudinal movement of anchor chain drives the gyro wheel and rotates, and the incline of anchor chain drives the rotation of hollow shaft to realize that 360 of hollow shaft rotates, make gyro wheel realization 360 rotate. The utility model discloses a multi -functional rotatory chock can realize can realizing by the moor direction of line of the complex that wire rope and anchor chain are constituteed that 360 is rotatory. This equipment has simple structure, rotates advantages such as nimble, safe in utilization, stand wear and tear, longe -lived.
