Description

Technical Field

[0001] The invention relates to the technical field of handicraft display, in particular to a display device for handicrafts. Background Art

[0002] A display device for arts and crafts is a device or facility specifically used to protect and display arts and crafts, including display cabinets. Some display cabinets are equipped with lighting systems that can better highlight the details and colors of arts and crafts and enhance the display effect. They are often used in museums, exhibition halls and other places to display precious arts and crafts.

[0003] In the existing arts and crafts display cabinets, arts and crafts are usually placed at a lower position to facilitate children's observation, but this is not convenient for adults to observe. Since adults are tall, they must bend down to observe when they want to observe the arts and crafts carefully. Bending down to observe frequently will make people tired quickly. When arts and crafts are placed at a higher position, adults do not need to bend down to observe, but it is difficult for children with shorter height to observe.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing arts and crafts display devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.
