An excavator is provided, including a body; a leader supported by the body; a head sliding along the leader; a first rod assembled with the head to elevate or rotate by the head; a rod clamp installed at a front end of the leader and clamping a second rod inserted into the ground; and a position fixture sliding along the leader by means of the head and fixing the position of the first rod when assembling the first rod and the second rod. Since the excavator according to the present invention allows an additional rod to be assembled with the rod clamped by the rod clamp due to the position fixture without causing vibration, the assembling work of additional rods can be easily performed. |
