Description
Technical Field
[0001] This utility model relates to the field of ceiling drilling, and more particularly to a ceiling drilling device. Background Technology
[0002] Suspended ceiling refers to the decoration of the top of a living environment. It generally refers specifically to the decoration of the ceiling and is an important part of interior decoration. The function of suspended ceiling is not only to increase the aesthetics of the room, but also to provide heat insulation, sound insulation and sound absorption. At the same time, it is also a concealed layer for electrical, ventilation and air conditioning, communication, fire protection and alarm pipeline equipment and other projects.
[0003] During some ceiling construction processes, in order to install downlights on the ceiling, it is generally necessary to drill holes in the ceiling to reserve enough space for the installation of downlights. At this time, drilling tools are required. Drilling tools are generally driven by a motor to rotate the drill bit. Then, the high-speed rotating drill bit is used to drill holes in the ceiling, and the waste material extracted during the drilling process is collected.
[0004] Most existing drilling tools are handheld, which requires workers to look up to see the drilling location. During the drilling process, a lot of debris is generated, and because the worker is looking up, the debris can easily fall into the worker's eyes, causing significant damage. In addition, because drilling tools lack a limiting structure during the drilling process, the drill bit can easily damage the ceiling due to drilling too deeply.
[0005] Therefore, it is necessary to provide a new ceiling drilling device to solve the above-mentioned technical problems. Utility Model Content
