description The invention relates to the technical field of measurement while drilling equipment, and discloses a device while drilling, which solves the problem that an existing drill bit is easy to vibrate during working, and comprises a drill rod, a bottom column is fixedly mounted at the bottom of the drill rod, a drill bit buffer mechanism is mounted at the bottom of the bottom column, and a connecting column is mounted at the bottom of the drill bit buffer mechanism. An outer groove is formed in the outer side of the connecting column; according to the drilling device, through cooperation of a disc and a rotating rod and cooperation of an arc-shaped plate and a fixing rod, when a drill bit vibrates, the disc vibrates, then the arc-shaped plate moves along the fixing rod, a fourth spring and a third spring stretch out and draw back, and through cooperation of a supporting cylinder, a supporting rod and the disc, a second spring stretches out and draws back; and then force is absorbed through the elastic action of a
