Construction workers determine the locations where holes need to be drilled, measure them, and mark them according to the needs of the project. Construction workers need to build scaffolding to increase their height and use electric hammers to drill holes. During the drilling process, the electric hammer itself is heavy, and the construction platform is a simple temporary construction without perfect protection measures. In addition, debris and dust are prone to fly out during the construction process. Such a construction method is prone to accidents and even the electric hammer may slip out of the hands. In order to reduce construction risks, a lifting device for ceiling drilling has appeared on the market. The device has a base, a vertical pole, an electric hammer, a lifting seat and other components. The electric hammer is fixed to the vertical pole by a throat clamp, and the height is adjusted by the lifting seat for drilling.
