Code reading and assigning synchronous marking terminal

The utility model relates to the technical field of marking equipment, and discloses a code reading and assigning synchronous marking terminal, which comprises a marking terminal body, the action output end of the marking terminal body is fixedly connected with a shell, and the inner top wall of the shell is fixedly connected with a mounting plate. According to the code reading and assigning synchronous marking terminal, by arranging an extension arm, a push-back seat, a guide rod, a limiting block, a connecting arm, a guide gear, a driving groove, an abutting plate, a first gear tooth, a second gear tooth and a limiting sliding way, after a marking terminal body drives a shell to move downwards, a marking mechanism makes contact with a workpiece, and the marking terminal body controls the marking mechanism to start marking; before a marking terminal body controls a shell to move upwards, an air cylinder is started to enable a marking mechanism to move upwards, meanwhile, the marking mechanism drives a guide
