Detailed Description

In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings. This utility model may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Examples

As shown in fig. 1 to 6, includes a lock body; the lock also comprises a locking mechanism which is arranged on the lock body;

the lock body comprises a lock head 1 and a lock cylinder 2, wherein the lock cylinder 2 is arranged in the lock head 1, and the locking mechanism is arranged at the left end of the lock cylinder 2;
