Multifunctional and multipurpose engineering driller

The multifunctional and multipurpose engineering driller comprises a movable base with the circular cross section, a first rotating shaft is rotationally connected to the center of the top end of the movable base through a bearing, a rotating disc is fixedly connected to the outer side of the first rotating shaft, and two symmetrically-arranged inverted-L-shaped vertical plates are fixed to the top end of the rotating disc; the multifunctional and multipurpose engineering driller is different from the prior art, the height of the drill rod can be adjusted through the first electric push rod, the height of the drill rod can be adjusted when a hole is drilled in a wall, the height of the drill rod can be adjusted through the first electric push rod, and the multifunctional and multipurpose engineering driller is convenient to use and high in practicability. According to the wall surface drilling device, firstly, the drilling rod is installed on the wall surface, so that drilling at different height positions of
