Zusammenfassung:	The utility model relates to the technical field of coal mine underground automatic drilling machines, in particular to a drill rod grabbing device. The drill rod grabbing device comprises a rack and a telescopic mechanism, a connecting part used for being connected with the mechanical arm is arranged on the rack, a driving clamping jaw is hinged to the rack, one end of the telescopic mechanism is hinged to the rack, the other end of the telescopic mechanism is hinged to the driving clamping jaw, the telescopic mechanism is used for driving the driving clamping jaw to rotate, and a driven clamping jaw is further hinged to the rack. The driving clamping jaw is provided with driving teeth, the driven clamping jaw is provided with driven teeth, and the driving teeth and the driven teeth are meshed together to achieve synchronous rotation of the driving clamping jaw and the driven clamping jaw. A driving clamping cambered surface and a driven clamping cambered surface which are used for clamping a drill rod are a
