Description

Telescopic connection structure and human body pillow Technical Field The application relates to the field of connecting structures, in particular to a telescopic connecting structure and a human body pillow. Background In many fields of machine manufacturing, building assembly, furniture production, etc., the connection and fixation between components are key links for realizing the functions of the product. The telescopic connecting structure is widely applied by virtue of the characteristics of flexibly adjusting the connecting length and adapting to assembly requirements of different sizes. For example, when furniture is assembled, the telescopic connecting structure can conveniently adjust the spacing of the parts, so that the installation efficiency is improved. However, the existing telescopic connecting structure lacks a reliable telescopic mechanism and is single in fixing mode, when the telescopic connecting structure is impacted by external force or vibrated for a long time, the fixing column is easy to loosen or even fall off, the service life and safety of the connecting structure are reduced, in addition, in most connecting structures, the elastic structure and the fixing column are not tightly matched, load is difficult to effectively transfer, and the use requirement under complex working conditions cannot be met. Therefore, a new telescopic connection structure is needed to solve the problems of unstable connection, poor adaptability and the like in the prior art. Disclosure of utility model In order to solve the technical problems, the application provides a telescopic connecting structure and a human body pillow piece, which are used for stable connection and positioning of components.
