Hinge mechanism

A hinge mechanism comprising:

• a fixation seat having
• a first containing indentation;
• a second containing indentation;
• the first containing indentation and the second containing indentation arranged axially up and down and opposite to each other, and in spatial communication with each other;
• a first guiding element mounted in the first containing indentation;
• a second guiding element mounted in the second containing indentation;
• the fixation seat comprising:
• an assembling plate;
• and
• a fixation component mounted at the assembling plate;
• the first containing indentation and the second containing indentation of the fixation seat formed in the fixation component;
• a first guided assembly, which is mounted at the first containing indentation of the fixation seat, corresponds to and abuts the first guiding element;
• a second guided assembly, which is mounted at the second containing indentation of the fixation seat, corresponds to and abuts the second guiding element;
• wherein the first guided assembly is guided by the first guiding element to move away from the second guided assembly or move back, and the second guided assembly is guided by the second guiding element to move away from the first guided assembly or move back;
• and
• a movable assembly comprising:
• a shaft axially movable and pivotable, mounted through the fixation seat, the first containing indentation, and the second containing indentation, the shaft optionally connected to one of the first guided assembly and the second guided assembly;
• and
• a door-fixing component mounted at the shaft, such that the door-fixing component is pivotable relative to the fixation seat via the shaft;
• wherein when the shaft is connected to the first guided assembly, the pivoting door-fixing component is moved up and down via the first guided assembly guided by the first guiding element;
• wherein when the shaft is connected to the second guided assembly, the pivoting door-fixing component is moved up and down via the second guided assembly guided by the second guiding element;
• the movable assembly comprising:
• a cover disposed in the door-fixing component and covering the fixation component of the fixation seat, the first guided assembly and the second guided assembly;
• the shaft mounted through the cover;
• the cover having
• two through holes respectively corresponding to the first guided assembly and the second guided assembly in position.
