Abstract:
1. A pivotable support shaft for a display, comprising a main shaft, a first connecting seat, a retaining plate and a retaining pin, wherein the main shaft is configured to be fixed to a mounting base member of the display, the first connecting seat is mounted on the main shaft in a manner that the first connecting seat is fixed in the axial direction of the main shaft and is able to rotate around the main shaft, the first connecting seat comprises a retaining surface, the retaining plate is mounted on the main shaft in a manner that it is restricted from rotating around the main shaft, the retaining plate comprises a first retaining edge, a second retaining edge, and a third retaining edge, wherein the retaining pin is mounted on the first connecting seat in a way of moving together with it, and wherein the retaining pin also has freedom of movement in the axial direction of the main shaft such that an axial moving path of the retaining pin is delimited by a first axial position and a second axial position, wherein, when the retaining pin is in the first axial position, the retaining pin extends into a space between the first and second retaining edges of the retaining plate, with the first and second retaining edges being in a rotating path of the retaining pin and the third retaining edge of the retaining plate being outside of the rotating path the retaining pin, such that rotation of the first connecting seat is limited to a first pivot range, and wherein, when the retaining pin is in the second axial position, the first and second retaining edges of the retaining plate are outside of the rotating path of the retaining pin and the third retaining edge of the retaining plate is in a rotating path of the retaining surface of the first connecting seat, such that rotation of the first connecting seat is limited to a second pivot range that is greater than the first pivot range.
