Press, with the vigorous development of electronic technology, computer technology brings people convenience, comfort, speed and other high-efficiency functions in life and work. Therefore, the application functions of electronic technology, computer systems, etc. are getting stronger and stronger, and the range is getting wider and wider. More and more, in addition to general personal computers, central processing systems are used to centrally control operators, such as: industrial computer rooms, central management and control systems for buildings, central management and control systems for automated plant operating systems, and central processing and control for audio, video and video playback. Systems, etc., will be connected to multiple computer hosts, servers, operation conversion systems, etc. at the same time through centralized management, and will be assembled inside a large chassis using a stacking method to form upper and lower stacked boxes. The box is pulled and pushed outwards to carry out the assembly or maintenance of various computer operating systems, and because of the combination of multiple operating host systems, when various computer operating systems need to perform related operations such as testing and updating programs, different layers must be installed one by one. The case can be pulled out of the case to facilitate inspection or related maintenance operations. Therefore, many stacked case boxes assembled in the case are equipped with a simple buckle structure. It is convenient to assemble the case into the case, or to pull the case out from the case.

However, for the currently used clasping structure, please refer to Figures 16 and 17. The movable handle A of the conventional case is locked to the object to be combined with the locking element A1 passing through the shaft hole A31 of the shaft portion A3. In the inner screw hole B11 of the cylinder B1, the movable handle A uses the cylinder B1 on the object to be combined to rotate and swing, and the locking member A2 on the movable handle A is used to achieve the purpose of locking. However, there are still many inconveniences and deficiencies when the handle A is actually assembled and applied. When the movable handle A is pushed and moved, it is locked and positioned through the buckle A2, and the movable handle A cannot be accurately positioned. , as long as it is slightly affected by external force, it is quite easy to loosen, causing the buckle A2 to be unfastened, resulting in inconvenience in use; furthermore, the movable handle A is only buckled to another object by the buckle A2, but the movable handle A does not have the design of limit and fixation. When the retaining member A2 is released from the retaining state due to external influence, the movable handle A will rotate and swing in any direction, and cannot be positioned stably.

Therefore, how to solve the current problems and troubles, troubles and defects of unstable rotation and difficult positioning of the rotating shaft on the handle is the direction that the relevant manufacturers in this industry are eager to research and improve.
