[0002] The stage is a space for actors to perform. It allows the audience to focus on the actors' performances and achieve an ideal viewing effect. In recent years, with the development of science and technology and the continuous pursuit of performance effects, the stage has also served as an important "prop" for performing arts activities. Therefore, the design of the stage structure and form determines and guarantees the performance effects of performing arts activities to a large extent.

[0003] A Chinese patent with authorization announcement number CN215107708U discloses a lifting stage, including a stage, a connecting tube, an oblique support rod and a telescopic leg, wherein a connecting block is fixedly installed inside the connecting tube, a limiting groove is fixedly provided at the bottom inner side of the connecting block, the bottom of the support plate is located at both sides of the connecting tube and is fixedly installed with an oblique support rod, an oblique support rod clamping block is fixedly installed on the top of the oblique support rod, a telescopic leg is fixedly installed on one side of the oblique support rod, a limiting block is fixedly installed on the top of the telescopic leg, a telescopic leg through hole is fixedly provided at the front end of the telescopic leg, a plug is fixedly installed at the front end of the telescopic leg through hole, and the length of the telescopic leg is adjusted according to the required height by means of the provided telescopic leg through hole and the plug, and by pulling out the plug, after the height is appropriate, the height of the telescopic leg is fixed by inserting the plug through the telescopic leg through hole, so that the device can be adjusted in height according to the required height, which is convenient to use.
