Lock device

A lock device, comprising:

• a housing with a front opening at an end;
• at least two rotating hooks disposed in the housing and being rotatable relative to the housing along a plane parallel to an X-Y plane having a X-axis and a Y-axis, each of the rotating hook comprising a front-end portion and a rear-end portion, the front-end portion at least partially protruding from the front opening, and the rear-end portion extending toward a direction opposite to the front-end portion;
• a driving device disposed in the housing and selectively moveable to change widths by which the front-end portions are opened respectively;
• and
• a lock body disposed in the housing, when the lock body is locked, the lock body restricting a movement of the driving device,
• wherein the driving device includes a driving portion being capable of moving along a Z-axis direction by different depths to be between the rear-end portions, respectively, wherein the width at the front-end portions of the rotating hooks is configured to change an amount which corresponds to the depth at which the driving portion is moved along the Z-axis direction, wherein, when the lock body is locked, the lock body is configured to restrict the movement of the driving portion along the Z-axis direction, the X axis, the Y axis, and the Z axis being orthogonal to each other.
