As the utility model discloses a preferred scheme, be equipped with the movable ball in the sleeve, the movable ball sets up the screw rod with between the movable rod. The surface friction coefficient of the movable ball is low, and the friction resistance on the end face is smaller in the rotation process of the screw rod, so that the steel ring is more labor-saving to disassemble and operate.

As the preferred scheme of the utility model, first jack catch tip and second jack catch tip all are equipped with the pawl. In-process is dismantled to the steel ring, the pawl can be gone into in the clearance between steel ring and the end cap for first jack catch and second jack catch are more stable with the steel ring butt, make the steel ring be difficult to appear jumping the bullet, promote the security of dismantling the process.

As the utility model discloses an optimal scheme, sleeve one end is equipped with the turn-ups that extends to the sleeve inboard, be equipped with on the movable rod with turn-ups complex dog. The turn-ups is restricted the movable rod in the sleeve, avoids the movable rod landing from the sleeve, prevents that the movable rod from losing.

As the utility model discloses a preferred scheme, the cover is equipped with the spring on the movable rod, the spring sets up the turn-ups with between the dog. The spring is in a compression state after being installed, the spring plays a role in supporting and pushing the stop block, so that the second clamping jaw has a tendency of returning, the spring can drive the movable rod and the second clamping jaw to return to an initial position when the movable rod loses a screw supporting and pushing effect, and the use is more convenient.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the pushing component drives the movable rod to move, so that the second clamping jaw moves to one side far away from the first clamping jaw, the steel ring gap is expanded, the steel ring falls off from the plug, the dismounting process is simple and convenient to operate, and the steel ring is easy to fall off;

2. but through relative movement first jack catch and second jack catch and steel ring breach both sides butt for dismantle in-process steel ring atress more stable, thereby make the steel ring drop more easily, reduce the risk that the steel ring bounced.
