Nailing device

The utility model provides a nailing device. The nailing device comprises a shell, a driving knocking mechanism, a control mechanism and a clamping mechanism. The driving knocking mechanism comprises a hydraulic oil cylinder, a knocking hammer arranged in the shell and used for hammering downwards, a compression spring arranged above the knocking hammer and used for applying downward impulsive force to the knocking hammer, and a rope driven by the hydraulic oil cylinder to stretch out and draw back and used for generating intermittent pressure to the compression spring through the knocking hammer. A nail to be nailed is clamped by the clamping mechanism, and the knocking hammer on the knocking mechanism is controlled and driven by the control mechanism to nail the nail to a position to be nailed. Specifically, the hydraulic oil cylinder is controlled by the control mechanism to do reciprocating motion, then the rope is controlled to drive the knocking hammer to compress the compression spring, and when the hy
