Abstract of the Disclosure A drill rod opening device for sectional-rod drilling equipment, which opening device (5) comprises a coupling frame (9), which can be coupled to a drilling machine (1) of the drilling equipment and which is provi- ded with a through hole (10) for a drill rod to be threaded into a drill rod shank of the drilling machine, and grasping means (13) mounted in the coupling frame. The grasping means are displaceable to a locking position, in which the grasping means extend into the hole in the coupling frame and, lock the rod to the coupling frame, and to a detaching position, in which the grasping means permit movement of the rod in relation to the coupling frame. The coupling frame is provided to be coupled to a front cover (4) of the drilling machine rotably but substantially axially undisplaceably in relation to the drill rod shank. The grasping means are provided to lock the drill rod in the locking position axially undisplace- ably to the coupling frame. The coupling frame (9) preferably comprises an internal annular bearing (12) coaxial with the through hole (10) for journalling the coupling frame rotably but axially undisplaceably to a cylindrical support element (25) provided in the front cover (4) of the drilling machine (1).
