At this point, the display panel 1 can be rotated to a suitable angle. Then, the locking handle 65 is rotated in the opposite direction to a vertical position. This overcomes the spring force of the locking spring 69, and the locking pin cap 67 of the locking pin 68 ensures a tight contact between the bottom of the circular blind hole and the corresponding end of the connecting cylinder 66 via the gear teeth 72. The display panel 1 can no longer rotate, thus stabilizing the relationship between the display panel 1 and inner rod 2 and completing the angle adjustment of the display panel 1. The above height and angle adjustments of the display panel 1 can be easily completed by a single operator.

[0032] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
