Claims

[Claims for Utility Model Registration] 1. One jaw block includes at least one jaw, and the jaw has an upright wall surface forming a concave arcuate side surface downward from the top of the jaw block, and A horizontal bottom wall surface connected to a lower part of the upright wall surface, an arcuate rib extending outward in parallel to the horizontal bottom wall surface on the upright wall surface, and a curvature of the arcuate rib on the horizontal bottom wall surface. a through-hole is provided at a location that coincides with the center, and includes retaining blocks equal to the number of jaws, each retaining block having at least two or more vertically formed retaining surfaces; A ring-shaped groove is provided on the outer periphery of the holding block, a cylindrical part is formed at the bottom of the ring-shaped groove, and the ring-shaped groove of the holding block is fitted with the arc-shaped rib of the jaw part. At times, the outer periphery of the cylindrical part is in close contact with the outside of the rib, and an axial hole is drilled in the bottom surface of the receiving block corresponding to the through hole of the jaw part, and the maximum rotation of the receiving block is made with the shaft hole as the center of rotation. The radius is made smaller than the radius of curvature of the upright walls of the jaws, and there are as many setting devices as there are jaws, each setting device consisting of a minimum of setting pins, connecting the through holes of said jaws and the retaining blocks. A jaw-shaped clamp that is built in between shaft holes and configured so that the receiving block can rotate on the jaw portion about the receiving block as an axis. 2. The diameter of the through-hole of the jaw is smaller than the diameter of the shaft hole of the receiving block, and the set pin is a cylindrical rod with a diameter of two steps,
The upper stage is made slightly thicker so that it can be inserted into the shaft hole of the receiving block, and the lower stage is made thinner so that it can be inserted into the through hole of the bottom wall surface. A spring is incorporated, and both ends of the spring are incorporated in a compressed state between the top wall of the shaft hole and the top of the set pin. Jaw-shaped clamp. 3. The diameter of the through-hole of the jaw is smaller than the diameter of the shaft hole of the receiving block, and the set pin is a cylindrical rod with a diameter of two steps,
The upper stage is made slightly thicker so that it can be installed in the shaft hole of the receiving block, and the lower stage is made thinner so that it can be installed in the through hole in the bottom wall surface, and the set pin is movable in the axial direction. installed in the shaft hole of the receiving block in a non-rotatable state;
A screw hole is drilled downward from the top of the set pin, an adjustment screw rod hole is drilled at the top of the retaining block, and the adjusting screw rod hole is connected to the shaft hole of the retaining block, An adjusting screw rod is rotatably incorporated in the adjusting screw rod hole, and the screw at the tip thereof is screwed into the screw hole of the set pin. Jaw-shaped clamp. 4. An auxiliary setting device is provided from the back side of the jaw of the jaw block toward the center of curvature of the jaw, a sleeve in the device is fixed to the jaw block, and a spring and a spring are inserted into the storage hole provided in the device. Utility model registration claims No. 1 - A steel ball is disposed, and the steel ball is exposed outside the upright wall of the jaw and is pressed inward, but is incorporated so as not to fall off.
