Building decoration and renovation project is to protect the main structure of the building, improve the physical properties and usage functions of the building and beautify the building. It uses decorative materials or ornaments to perform various treatments on the internal and external surfaces and spaces of the building. In the process of decoration, holes are often drilled to install fixing bolts and other structures. Dust will be generated during the drilling process. In order to prevent environmental pollution and decoration workers from accidentally inhaling dust and affecting their health, dust-proof devices are used to prevent dust when drilling holes.

The existing dust-proof devices are also mostly of fixed sizes and are only suitable for drilling holes with drill bits of corresponding sizes. The scope of application is small. In order to solve the shortcomings of the existing technology, we propose a dust-proof device for drilling holes in building decoration projects. Utility Model Content
