A tubular lever lock includes a protruded connection part formed at the cross section of a pawl which slides along an inner spindle and interfaced with the operation of an eccentric hole of an operation globe. The spindles are structured to form and to protrude with a square pole passing through a latch by an appropriate distance. A key holder is formed on an outer bundle and is connected with a lock cylinder of an outer spindle, which enables a catch hub installed inwardly and elastically to rotate. With regard to the inner bundle and outer bundle, when built in, the key holder of the outer bundle causes connection with the operation globe through a square hole of a catch hub as well as a hole of the square pole.
