Three wrong operation methods of drill rod: 1. When pressed, no pressure point can be found, and a mechanical locking rod is used as a friction rod. The contact surface between the inner rod and the two rods is very small. In a short time, the upper end of the rod and the sides of the two rods are severely worn, creating a lever or scroll button. 2. During operation, the front track of the main engine is raised, using the rear of the mast, a part of the mast is subjected to the backward force F1 of the power head and the inner part of each pole. The vertical force F2 is maintained, and both forces form a moment to a portion of the rod. The top assembly of the top and bottom of a part of the rod is easy to cut off. 3. In the process of placing the drill pipe

3. In the process of placing the drill rod, there is no buffer when two adjacent rods are in contact, which makes the inner rod rotate together with the inner rod of the outer rod.
