Concrete quality inspection sampling device

The invention relates to a concrete quality inspection sampling device, and relates to the field of concrete detection.The concrete quality inspection sampling device comprises a supporting frame, a drill bit and a driving assembly used for driving the drill bit are arranged at the upper end of the supporting frame, an avoiding opening used for allowing the drill bit to pass through is formed in the lower end of the supporting frame, a bottom plate is arranged at the lower end of the supporting frame, and one end of the bottom plate is movably connected with the supporting frame; when the base plate and the supporting frame move relatively, the other end of the base plate is separated from the position between the avoiding opening and the drill bit. Opening and closing of the avoiding opening can be achieved through relative movement of the bottom plate and the supporting frame. When direct sampling is carried out on the ground, the bottom plate keeps away from the position between the drill bit and the avoid
