An exemplary elevating mechanism used for a flat-panel display monitor includes a support structure, a sliding structure, and a pneumatic cylinder. The support structure includes a pair of guide rails. The sliding structure is mounted to the support structure and is capable of sliding along the guide rails. The pneumatic cylinder includes a cylinder body, a piston shaft, and a first piston. The cylinder body is connected to the support structure. The piston shaft includes a first end received in the cylinder body, and a second end opposite to the first end connected to the sliding structure. The first piston is positioned in the cylinder body and partitions the cylinder body into two chambers. The two chambers are filled with gas. The first piston is fixed to the first end of the piston shaft and defines a through hole for communicating the two chambers.

An exemplary hinge positioning structure (20) includes a base (22), a pivot shaft (24) engaged in the base, a pivot shaft gripper (264), and a resilient member (266). The pivot shaft is rotatably engaged in the base. The pivot shaft gripper is sleeved on the pivot shaft. An end of the pivot shaft gripper is engaged with the base so that part of the pivot shaft gripper is fixed to the base. Two ends of the resilient member are connected to the base and another end of the pivot shaft gripper, respectively. The resilient member applies a force on the pivot shaft gripper so that the pivot shaft gripper tightly grips on the pivot shaft, and the pivot shaft gripper is relaxed by an external force for allowing the pivot shaft to rotate relative to the base. The present invention further provides a hinge positioning unit (26).

A fastening system includes a first connecting member, a second connecting member, a rivet, and an elastic member. The second connecting member is positioned on the first connecting member, and defines a receiving groove. The rivet extends through the first connecting member and the second connecting member, and rivets the first connecting member and the second connecting member together. The rivet forms a riveting flange at an end adjacent to the second connecting member. The elastic member is received in the receiving groove of the second connecting member, and compressed by the riveting flange to generate a predetermined positive pressing force between the first connecting member and the second connecting member. A fastening device for manufacturing the fastening system is also provided.

An exemplary hinge positioning structure (20) includes a pair of first leaves (22), a pivot shaft (262) rotatably engaged in the pair of first leaves, and a pair of pivot shaft grippers (24) sleeved on the pivot shaft. An end of each pivot shaft gripper engaged with each of the first leaves respectively so that the end of each pivot shaft gripper is fixed relative to each of the first leaves. The hinge positioning structure further includes a resilient member (266), two ends of the resilient member connected to the pair of pivot shaft grippers respectively, and applying a force on the pair of pivot shaft grippers so that the pair of pivot shaft grippers tightly grip the pivot shaft, such that the pivot shaft is prevented from rotating relative to the first leaves.

A fastening device for manufacturing a fastening system is disclosed. The fastening system includes a first connecting member, a second connecting member, a rivet riveting the first connecting member and the second connecting member together, and an elastic member compressed by the rivet. The fastening device includes a rivet head forming tool, a positioning assembly positioning the first connecting member, a first driving assembly driving the rivet head forming tool to move, a second driving assembly driving the second connecting member to rotate, and a force measuring module. The force measuring module is configured for measuring the positive pressing force between the first connecting member and the second connecting member, and generating a control signal to stop the first driving assembly and the second driving assembly when the positive pressing force between the first connecting member and the second connecting member reach the predetermined force.
