っかりとした締付固定ができる。The one handle mounting mechanism according to the present invention constructed as described above, when the two clamps are tightened by the clamp, the clamps move in the direction approaching each other. The diameter of the insertion hole is reduced, and the inner periphery of the insertion hole is fixed to the outer periphery of the operation rod 1 in close contact. And, since the through hole of one of the clamping members is larger than the inner diameter of the through hole of the other clamping member, and is configured to have a moving gap, the two clamping members are Along with moving in the direction approaching each other, the one clamping and holding body moves inward in the radial direction of the operation rod. Due to the movement of the one clamping and holding body in the above-mentioned direction, the inner peripheral portion protruding end side of the clamping and holding body moves so as to be wound around the outer periphery of the operation rod and is pressed against the outer periphery of the operation rod. In other words, the movement of the one clamping body in the direction approaching the operation rod makes it firmly pressed against the outer periphery of the operation rod, so that the inner periphery of the insertion hole and the outer periphery of the operation rod The contact pressure increases due to the strong pressure contact with, and firm tightening and fixing can be performed.

The inner periphery of the fitting hole is tightly fixed. Simultaneously with the operation, the wedge piece is moved toward the center of the operation rod by the tapered notch portion of the two clamping members, and the concave curved surface is closely attached to the outer periphery of the operation rod. The operation stick is fixed by pressing. That is, since the outer periphery of the operation rod is sandwiched between the inner peripheral surface of the insertion hole and the concave curved surface of the wedge piece, and is tightly fixed by pressure contact, the inner periphery of the insertion hole is Due to the strong pressure contact with the outer periphery of the operation rod, the contact friction increases, and a firm tightening and fixing can be performed.

The inner diameter of the insertion hole 26 is fixed to the outer circumference of the operation rod 11 in close contact. Then, the bolt through hole 2 of the right clamping body 25b is formed.
8b is configured to be larger than the inner diameter of the bolt through hole 28a of the left clamping body 25a and to have a relatively large moving gap with the outer diameter of the clamping bolt 29. Therefore, the two clamping members 25a,
The right clamping body 25b moves in the direction c of the operation rod 11 along with the movement 25b in the directions a and b approaching each other. By movement into the direction c of the clamping holding member 25b of the right side, the inner peripheral portion projecting end 25b 1 of該締with holding member 25b is moved to involve an outer periphery of the operating rod 11, the manipulation rod 11 Is pressed against the outer periphery of That is, the movement of the right clamping body 25b in the direction c causes the outer periphery of the operation rod 11 to be firmly pressed against the entire inner periphery of the insertion hole 26. Due to the strong pressure contact between the inner periphery of the hole 26 and the outer periphery of the operation rod 11, contact friction increases, and a firm tightening and fixing can be performed.
By increasing the effective area of pressure contact / contact in this way,
The screwing of the tightening wing nut 31 into the tightening bolt 29 can be easily performed by rotating and tightening the tightening wing nut 31 with a finger without the need of a special tightening tool such as a spanner. And it can be fixed firmly.
