Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing devices for posting couplets, in particular to a device for posting couplets. Background Art

[0002] In my country, couplets are posted during the Spring Festival and some special festive occasions. The traditional method of posting couplets is generally to use glue or adhesive strips to stick the couplets on the wall or pillars. The traditional pasting method easily leaves marks on the wall that are difficult to clean and affect the appearance. Every year when replacing new couplets, the old couplets on the wall must be torn off, and the height position needs to be re-identified when posting new couplets. When posting some higher positions, multiple people are required to assist in climbing by means of stairs or other high-altitude methods. The traditional pasting method is time-consuming, labor-intensive, and cumbersome, and there are hidden dangers such as insecurity.

[0003] The prior applied patent, patent application number: 202321454820.9, patent name: A non-sticking couplet fixing device, provides a couplet fixing device that can facilitate the posting of couplets. In this patent, wing plates are provided on both sides of the main back plate of the couplet, which play a certain protective role on the couplet. However, when the wind volume is large, the wind will blow into the gap of the wing plate, and then flow into the space between the couplet and the main back plate. Long-term wind intake will slowly blow up the couplet, or blow it crooked, affecting the posting effect of the couplet. Utility Model Content
