The invention is a locking mechanism, including a screw (1), a nut (2), a washer (3), a spring (4), a restricting shaft (6), a gear shaft (7) and a cover (8). The gear shaft (7) and the restricting shaft (6) are placed inside the cover (8). Below the gear shaft (7) is the restricting shaft (6). The top part of the restricting shaft (6) is a wedge-shaped structure. The lower part of the restricting shaft (6) has the spring (4). The wedge shaped structure at the top of the restricting shaft (6) fits into the groove between the two teeth of the gear shaft (7). The cover and the restricting shaft (6) co-operate to fix the upper and lower parts of the shaft (6). Through back and forth movements of the restricting shaft (6), the restricting shaft (6) and the gear shaft (7) engage or separate to achieve a locking and an unlocking state of the locking mechanism. The invention addresses the convenience and reliability problems of the operation for existing locking mechanism. |
