When height adjustment is required, the adjustment rod 201 is rotated, and the support frame 3 is pushed upward by the threaded connection between the support rod and the support frame 3. At the same time, the support frame 3 is slidably connected to the cross frame 2 to maintain the stability of the support frame 3. After reaching the specified height, the support frame 3 is positioned by the self-locking of the thread. When the width of the painting changes, the support arm 4 can be pushed to move laterally along the support frame 3 to adjust the width, thereby meeting the fixing needs of paintings of different widths.

[0031] Preferred embodiments, in combination Figure 2 As shown, the bottom of the crossbar 2 is equipped with a control motor 202 connected to the adjusting rod 201, which can be quickly adjusted by electric drive without manual rotation.
