Description

Easy-to-adjust length agile telescopic device

The invention relates to a telescopic device, in particular to an agile telescopic device that is easy to adjust the length.

Technology is changing with each passing day. People enjoy the sound, light and entertainment effects brought by technology. In recent years, the cultural and creative industry has flourished. The industry combines culture, communication and digital content in the exhibition and stage performances, making the exhibition and stage performances better. rich.

In the prior art, facilities such as landscaping, decorations, or lamps are applied to the exhibition hall or stage. Generally speaking, the setting methods are static or fixed. However, this setting method is usually easy to make the scene feel monotonous. The processing of the above-mentioned facilities to produce changes is obviously not in line with the needs of cost and reality for modern people. Furthermore, most of the existing exhibition or stage lighting technology is to erect lamps on the ground. The user can direct the light emitted by most lamps to a fixed direction, and externally install control equipment for controlling these lamps to change the light. In addition, if the user wants to make most lamps present other visual effects during the performance , The above facilities must be moved, and usually expensive professional mobile equipment must be used, or even the track must be laid before the aforementioned facilities can have a mobile visual effect.

It can be known from the foregoing that, in the prior art, the landscaping, decorations, or lighting settings on the exhibition field or stage are easy to make the visual experience monotonous. To display special mobile effects, expensive mobile equipment must be used. For users, It is inconvenient to use and does not meet the cost. Therefore, in order to make it convenient for users and to change the visual effects of the exhibition venue and stage performance, it is really necessary to propose a better solution.

In view of the above-mentioned shortcomings of the prior art, the main object of the present invention is to provide an agile telescopic device that is easy to adjust the length.
