[0020] In the above specific technical scheme, the drilling rig is assembled on the vehicle to form a whole, which has good mobility and operability and strong maneuverability. By setting the diagonal support cylinder 6, the inclination angle of the fixed arm 4 can be controlled, and the mobile arm 5 is lifted and moved along the fixed arm 4 through the boom support cylinder 8. The slide 9 is connected to the fixed arm 4 through a chain mechanism. The power head mechanism 7 is installed on the slide 9. The moving speed of the power head mechanism 7 is twice the moving speed of the mobile arm 5. A drill rod fixing mechanism is set to facilitate the installation and disassembly of the drill rod.

[0021] The drill rod fixing mechanism includes a fixing frame 10 fixedly connected to the fixing arm 4, both ends of the fixing frame 10 are connected to the clamping cylinder 11 through a pin shaft, the output end of the clamping cylinder 11 is connected to the clamping clamp 12, and the clamping cylinder 11 is started, and the clamping cylinder 11 drives the clamping clamp 12 to move in the direction of the drill rod, and the two clamps 12 cooperate to tighten the drill rod.
