[0058] In the present embodiment, the first connecting relationship is adopted. The second connecting relationship is a simple and equivalent alternative of the first connecting relationship. In the second embodiment described below, the third connecting relationship is adopted.

[0059] The adjusting member 3 is fixedly connected to one end of the connecting rod 5, and is preferably arranged in an integrated manner with the connecting rod 5. A thread is arranged on the other end of the connecting rod 5 to connect the tightening member 4. During assembly, the connecting rod 5 is arranged to pass through the two bosses 110 and the hinge arranged between the two bosses 110. When the adjusting member 3 is rotated, the connecting rod 5 is driven to rotate, the tightening member 4 is driven by the thread, and the tightening member 4 moves towards the side close to the adjusting member 3 to be clamped with the first clamping part 111 and the second clamping part 211, thereby achieving the locking of the reading angle. Conversely, when the adjusting member 3 is rotated, the tightening member 4 moves away from the adjusting member 3 to be disengaged from the first clamping part 111 and the second clamping part 211, thereby completing the first step of the adjusting process of the reading angle.
