The invention discloses a cylinder joint drill rod convenient to replace. The cylindrical joint drill rod comprises a hollow cylinder; the right side of the hollow cylinder is fixedly connected with adrill rod body; the right side of the drill rod body is fixedly connected with a joint; the top and the bottom of the right side of an inner chamber of the joint are each horizontally provided with aguide gap; one end, far away from the guide gaps, of the inner chamber of the joint is provided with an arc-shaped groove; one end, far away from the arc-shaped groove, of the inner chamber of the joint is provided with a circular groove; two springs are correspondingly welded to the top and the bottom of the left side of the inner chamber of the joint; the right side of each spring is provided with a pressing plate by means of welding; and a drill bit is arranged at the right side of the joint. According to the cylinder joint drill rod disclosed by the invention, by cooperation of the guidegaps, the arc-shaped groove, the circular groove, the springs, the pressing plates, the drill bit, a guide block and a limiting cylinder block, a user can conveniently replace the joint, thus the problem that a traditional joint drill rod is inconvenient to replace by the user is solved; time and efforts are saved; the labor intensity of the user is alleviated; and the work efficiency of the useris improved.
Description
technical field [0001] The invention relates to the technical field of drill pipes with joints, in particular to a drill pipe with cylindrical joints which is easy to replace. Background technique [0002] The rods connected in the drilling tool to transmit power, when the user drills the wall, need to use the drill bit and the drill rod, and the user needs to use the joint drill rod to fix the drill bit. However, the traditional The jointed drill pipe is not convenient for the user to replace. The traditional jointed drill pipe is generally fixed through the thread groove and the screw rotation, which requires the user to rotate for a long time, and then the user uses tools to fasten the joint and the drill bit. The threaded rod and the screw The threaded groove is easy to rust, and at the same time consumes time and labor, increasing the labor intensity of use. Contents of the invention [0003] The object of the present invention is to provide an easy-to-replace cylind...
