The invention discloses a clipping device and a construction machine. The clipping device comprises a clipping head, a clipping arm of which the head end is connected with the clipping head, a rotating mechanism which comprises a rotating part, a fixed part, and a rotating driving part that drives the rotating part to rotate relative to the fixed part; the rotating part is connected with the tail end of the clipping arm. The clipping device can meets the construction demand of the shallow tunneling method and is applicable to the construction of shallow-buried excavation; compared with the existing manual excavation, the clipping device can greatly reduce the labor intensity and increase the construction efficiency.
