Technical Field

[0001] The utility model relates to the technical field of agricultural culture, and particularly relates to an adjustable agricultural culture display screen. Background Technique

[0002] Agricultural culture refers to a cultural form formed in the long-term agricultural production practice, which includes two aspects: material culture and spiritual culture related to agriculture. Agricultural culture is an important part of the development of human civilization. Especially in a long-historical farming society like China, agricultural culture is deeply rooted in people's daily life and social structure. The content of agricultural culture is extensive, including the following main aspects: agricultural production technology, agricultural knowledge and wisdom, agricultural festivals and customs, agricultural literature and art, etc.

[0003] In order to improve the popularity of agricultural culture, display screens are needed for publicity and display. During the use of existing display screens, new cultural content needs to be rewritten and pasted regularly. Usually, they can only be displayed vertically and cannot be placed horizontally when new content needs to be rewritten, making it inconvenient to replace the content. Moreover, existing display screens lack a certain display angle adjustment function, which limits their display effect. Content of the Utility Model
