Description

[0001] This application is a divisional application of the utility model patent application with application date of October 18, 2023, application number CN2023227952794, and invention name “A pendant base”. [Technical field]

[0003] For the convenience of life, objects are usually hung by using a hanging piece in conjunction with a base body fixed to a wall. The base body is generally fixed to the wall by glue or screws.

[0004] However, the base fixed with glue has the following defects: 1. The manufacturer has applied glue to the base body before leaving the factory, and the glue applied is only a thin layer, which makes the base body not firmly attached to the wall and the base body will fall off after a long time; 2. When people install the base body, it is very easy to stick the base body crooked. If the base body is removed and re-pasted, the viscosity of the glue will be greatly reduced, making the base body not firmly attached to the wall; 3. For example, if people inject glue into the concave cavity of the base body for pasting and fixing, there will be too much glue injection, resulting in waste; if the glue injection is insufficient, there will be problems such as the base body not being firmly attached to the wall.

[0005] Therefore, the utility model is proposed to solve the problems of the base body not being firmly attached to the wall and too much or too little glue being injected. [Utility Model Content]
