[0019] 1. The present utility model includes two adjustable telescopic support frames. By adjusting the length of the adjustable telescopic support frames until the two ends of the adjustable telescopic support frames contact the upper and lower bottom surfaces of the tunnel, the transverse slide rail and the rock drill are fixed in front of the working face. The rock drill mounting slider is fixedly connected to the rock drill. Then, the height of the transverse slide rail is adjusted through the sliding connection component, and thus the height of the rock drill is adjusted.
