1. A lock, comprising:
a housing, wherein an end of the housing comprises a front-end opening facing a same direction as an extending direction of an X-axis, the front-end opening deviates from a center of a section parallel to a Y-Z plane of the end, and the X-axis, a Y-axis, and a Z-axis are orthogonal;
a rotating hook, arranged in the housing and rotatable relative to the housing, and comprising a front end and a rear end, wherein the front end at least partially extends out of the front-end opening, and the rear end extends in an opposite direction to the front end;
a driving apparatus, arranged in the housing, and movable to change an opening width of the front end; and
a lock body, arranged in the housing, wherein when the lock body is locked, the lock body restricts movement of the driving apparatus;
wherein the rear end is provided with a driving groove, and the driving apparatus comprises a driving portion extending into the driving groove along a Z-axis direction, when the lock body is unlocked, the driving portion is movable along the X-axis direction to rotate the rotating hook relative to the housing along a plane parallel to an X-Y plane to change the opening width of the front end, and when the lock body is locked, the lock body restricts the movement of the driving apparatus;
wherein the driving apparatus comprises:
a force applying part, penetrating the housing, movable along a plane parallel to the Y-Z plane, and comprising a force applying portion arranged in the housing;
a first driving part, arranged in the housing, abutting against the force applying part, and movable along the X-axis direction;
a second driving part, arranged between the first driving part and the rotating hook in the housing, abutting against the first driving part, movable along the X-axis direction, and comprising the driving portion;
a first elastic apparatus, arranged at a side of the first driving part to provide first elastic force, so that the first driving part approaches the second driving part; and
a second elastic apparatus, arranged at a side of the second driving part to provide second elastic force, so that the second driving part is far away from the rotating hook, wherein a component of the first elastic force along the X-axis direction is larger than a component of the second elastic force along the X-axis direction, wherein
when the lock body is unlocked, the force applying part is movable towards an inside of the housing, pushes the first driving part to move along the X-axis direction to be away from the rotating hook to move the second driving part along the X-axis direction to be away from the rotating hook, and drives the driving portion to move along the X-axis direction to rotate the rotating hook relative to the housing along a plane parallel to the X-Y plane.
