The force can push the moving member 50 back to the first position from the second position (as shown in FIG. 4).

In other embodiments, the adjusting member 60 may be, for example, a screw or an adjusting member designed by using a mechanism such as a mast, a toggle, or the like.

For practical application, reference may be made to FIG. 6 , which is a sales terminal (POS). The fixing base 10 is fixedly connected to a desktop display 100 by a screw lock, and a vacuum fluorescent display 200 for providing customer reference is provided. The shell member of the Vacuum Fluorescent Display (VFD) is engaged with the hanging portion 291 of the rotating base 20, and the desktop display 100 and the vacuum fluorescent display 200 are respectively fixed to opposite ends of the fixing base 10, so that With the stepless angle adjustment structure of the present invention, the effect of easily adjusting the relative positions of the displays can be achieved. It can be seen from the above that the stepless angle adjusting structure of the embodiment of the present invention can utilize the actuation of the actuating structure to change the position of the moving member, thereby changing whether the rotating seat is in a rotatable state or in a positioning state, so that not only the rotating seat is rotated or positioned.
