摘要： PROBLEM TO BE SOLVED: To provide an expandable head which eases excessive excavation resistance generated at the time of expanding expandable blades, positively carries out contraction of the expandable blades, and is solid and inexpensive.
SOLUTION: The expandable head does not use a hydraulic cylinder or a link mechanism for expanding the expandable blades, and it is essentially set such that the expandable blades are locked in a contractive state beforehand during ordinary excavation, but that the expandable blades are expanded by using external force after cancellation of locking during expanded excavation. A head rod of the expandable head is formed of an upper driving shaft having the expandable blades axially mounted on an external periphery in a longitudinally expandable and swayable manner, and a lower driven shaft having an excavation head protruded from an external peripheral surface, and the shafts are fitted to each other in a manner rotatable and axially slidable with respect to each other. Herein the head rod thus formed has key grooves each with an auxiliary key groove bored in an area between the upper driving shaft and the lower driven shaft, and keys engageable with the respective key grooves.
