摘要： PROBLEM TO BE SOLVED: To provide a retractable bit capable of returning a bit to a widened state with ease after the diameter has been reduced to a contracted state and avoiding collision of mutual bits.
SOLUTION: Two rotary regulation faces 12, 13 are formed in the outer periphery of a pit adapter 4 and a stepped part 14 is formed at the upper part of a rotary regulation face and an adapter guide 15 is provided in the body 1. In an adapter guide 15, rotary regulation faces 16, 17 during contraction in diameter, regulating the rotation of the bit adapter by the face contact with one rotary regulation face 12, 13 in a diameter contracted condition, and a rotary regulation face 18 during contraction in diameter, regulating the rotation of the bitadapter by the face contact with the rotary regulation face 12, are formed in a diameter contracted condition. One 16 of two rotary regulation faces during contraction in diameter, shows the axial length in which the face contact with the rotary bregulation face 12 of the bit adapter is releaved when the bit adapter 4 is in the projected position and the lower end face of the part 15a regulating one rotary regulation face 16 has a slant face 19 engageable with the stepped part 14.

摘要： PROBLEM TO BE SOLVED: To provide a rod chuck holding circuit for a boring machine capable of positively preventing a lowering of holding force to a drill rod by preventing the drop of pressure in a hydraulic cylinder for driving a chuck mechanism. SOLUTION: The rod chuck holding circuit 3 is provided with the hydraulic cylinder 4 for driving the chuck mechanism 2 for holding the drill rod 1; a holding pipeline 5 for putting the chuck mechanism 2 in the holding state by feeding pressure oil to one chamber 4a of the hydraulic cylinder 4; and a release pipeline 6 for putting the chuck mechanism 2 in a hold release state by feeding pressure oil to the other chamber 4b of the hydraulic cylinder 4. The pressure oil is supplied to the holding pipeline 5 through a first connecting pipeline 16 with a shuttle valve 15 and through a second connecting pipeline 17 with a check valve 18 from a motor driving circuit 10 for driving a hydraulic motor 11 for rotating the drill rod 1.
