PURPOSE: A vibration type sending string tool is provided, in which the sending string tool has a spherical head and a vibrator incorporated into the tool, to thereby allow the tool to easily avoid obstacles during line connection work. CONSTITUTION: A sending string tool includes a front end unit(200) having a spherical head(210) with a vibrator(240) incorporated into the head; a main body(100); and an elastic member(300) for connecting the front end unit and the main body. The spherical head includes a lower base(230) having a power supply terminal(231); an upper cover(220) coupled to the lower base and which has a hollow portion formed inside of the upper cover and a through hole formed at the center of the upper cover; a vibrator(240) interposed between the lower base and the upper cover, and which has a connection terminal(241) connected to the power supply terminal; a spring(250) interposed between the vibrator and the lower base so as to space the power supply terminal apart from the connection terminal; and a switch(260) coupled to the outer periphery of the upper cover, and which presses, through a press rod(261) the vibrator when an external force is applied, so as to allow the connection terminal to contact the power supply terminal.
