The invention relates to a narrow multi-angle boring tower device. The existing car anchor rod borer device commonly has the defects of larger size, heavy weight and complex structure; most of devices with small size are single-arm boring towers which have single function; the position of a borer must be continuously adjusted in roadway construction; at the same time, one set of device can not complete the anchoring construction of roof plates and lateral walls, so the efficiency is low, and the adaptability is poor. The narrow multi-angle boring tower device comprises a box body, an arm unfolding mechanism, a rotating cylinder, a pitching cylinder, a mounting bracket and a boring tower, wherein the arm unfolding mechanism comprises a telescopic cylinder and a mounting arm, and the telescopic cylinder arranged in the arm unfolding mechanism is connected with the box body. One end of the rotating cylinder is connected with the mounting arm of the arm unfolding mechanism by a bolt, and the other end is connected with the mounting bracket by a bolt. The boring tower is arranged on the mounting bracket by a pin roll or a bolt in parallel, and the pitching cylinder is arranged between the boring tower and the mounting bracket. The narrow multi-angle boring tower device has the advantages of high structural strength, small size, multi-angle moving, wider working range, high efficiency, high integration, assistant reducing and simple and easy operation.
