Abstract
The invention provides a holder. The holder comprises a first slip base and a second slip base. The first slip base comprises a first groove and a first base body. The second slip base comprises a second groove and a second base body. The first slip base and the second slip base are buckled. A through hole is formed by the first groove and the second groove. The first end of the first base body makes contact with the first end of the second base body. Preset distance is reserved between the second end of the first base body and the second end of the second base body. According to the holder, damp coal and rock powder left in a gap between the first slip base and the second slip base leaks to the outside of the holder through a gap between the second end of the first base body and the second end of the second base body, and therefore the damp coal and rock powder can be prevented from being stacked in the gap of the first slip base and the second slip base, the holder can clamp a drill rod, and the safety of down-hole operation is improved.
