Abstract: A swivel has a main body, a longitudinal locking unit, and a lateral locking unit. The main body has a longitudinal axis, a lateral axis being perpendicular to the longitudinal axis, an accommodating gap, a through hole, a threaded hole, and a receiving space. The accommodating gap is disposed between and communicates with the through hole and the threaded hole. The receiving space is disposed along the lateral axis and communicates with the through hole. The longitudinal locking unit has a shaft mounted through the through hole and screwed with the threaded hole. The lateral locking unit has a lateral locking component mounted in the receiving space and able to block the shaft to prevent the shaft from falling off from the accommodating gap. The swivel is capable of multiple locking manners to securely connect a belt and a heavy object.
