The invention discloses a butt-joint type locking rod for a printing plate for printing and dyeing. The butt-joint locking rod comprises a left fixing plate and a right fixing plate. A first super glue layer is arranged on the outer side of the left fixing plate. A left threaded rod is connected to the inner side of the left fixing plate. A left rotating pipe is mounted on the left threaded rod in a sleeved manner. A left locking pad is arranged at the end of the left rotating pipe. The outside-oriented surface of the left locking pad is recessed inwards. A second super glue layer is arranged on the outer side of the right fixing plate. A right threaded rod is connected to the inner side of the right fixing plate. A right rotating pipe is mounted on the right threaded rod in a sleeved manner. A right locking pad is arranged at the end of the right rotating pipe. The outside-oriented surface of the right locking pad is recessed inwards. The right locking pad corresponds to the left locking pad. By the butt-joint type locking rod, the printing plate placed between the right locking pad and the left locking pad is conveniently clamped by the right locking pad and the left locking pad, and placement of printing and dyeing components is facilitated.
