Further set forth content of the present utility model below in conjunction with Figure of description and embodiment.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the right elevation of Fig. 1;

Fig. 3 is the locking lever pulling piece scheme drawing.

The specific embodiment

Lock collar 1 adopts the aluminum alloy inblock cast to become discoid, on lock collar 1, be respectively arranged with and be positioned at RC circular groove 9, have lock core hole 12 at groove 9 centers, lock collar 1 limit is provided with locating piece 15, and on locating piece 15, have a knock hole 16, because being set, tapered end pull bar 4 can be 2-4, present embodiment is chosen 4, locating piece 15 also is provided with 4,4 tapered end pull bars are more stable than 2 or 3 tapered end pull bars, shape is colluded in end formation at the tapered end pull bar, and on the tapered end pull bar, being fixed with a retracing spring washer 14, retracing spring 5 is enclosed within on the tapered end pull bar 4, because lock core 2 both can move in the direction of the clock, the retracing spring washer also can rotate counter clockwise, so can be arranged near the hook end.Also can be arranged near rod head end, this will depend on the rotation direction of lock core, and tapered end pull bar 4 is provided with retracing spring catch 14, is used for the pressed home spring, and the tapered end pull bar is resetted.Locking lever pulling piece 3 is relatively more crucial members of the utility model, it is a gyro-rotor, integral body is put into the circular groove 9 of lock collar 1, the arc chute of offering on it 10 also is fixed with the number of tapered end pull bar 4, the heart also offers the mesopore 11 of socket lock core 2 therein, arc chute 10 is arranged symmetrically and evenly around the center of circle, its arc can be involute and also can be circular arc, its arc chute 10 is decided on the length that tapered end pull bar 4 bar heads stretch into lockhole with length, locking lever pulling piece 3 profiles can be circle, also can make butterfly according to arc chute 10 shapes.Lock core 2 can be directly bought in market according to diameter, and after core 2 packed into the mesopore 11 of the lock core hole 12 of lock collar 1 and locking lever pulling piece 3, fixing by lock core spacer 6, jump ring 8 was arranged between lock core 2 and the locking lever pulling piece 3.In order to make theftproof performance better, be bonded with alarm switch 13 at the center of cover plate 7, this switch connects electronic alarm 18 by lead, in case lock core 2 is disclosed the end by key, just press alarm switch 13, annunciator 18 is rung,, on the lockhole of lock core 2, be provided with a cover of dust 17 for playing antitheft effect.
