Described snap close is fixed in lock housing and is connected in rotation process in draw-in groove that lock pin is arranged with lock housing, and the other end of the relative draw-in groove of described lock pin is flexibly connected with U-shape lock hook.

By adopting technique scheme, U-shape lock hook coordinates with lock pin and forms locking space, key inserts in the endoporus of lock ring and retainer, rotates lock ring by the key arranged on the key, the tolerant groove on all lock rings and the tolerant groove on lock tube to time corresponding brake bar is embedded on lock ring, lock housing and lock tube relative motion, the fixture block be fixed in lock housing rotates and is fastened in the draw-in groove of lock pin, realizes the process of locking, structure is simple, and safety is high.

The utility model is set to further: described lock pin is made up of straight steel.

By adopting technique scheme, the lock pin be made up of straight steel can tempering, increases the hardness of lock pin, makes it not easily be destroyed by industrial scissors, improve the safety of this U-shape lock.

The utility model is set to further: the endoporus of described retainer is rounded.

By adopting technique scheme, the effect being fixed on retainer in lock housing main clamps the lock ring in adjacent two retainers, because the endoporus of lock ring is suitable with key, endoporus is set to circular retainer, endoporus area is maximum, and the scope of application is the widest, easy to process.
