| PURPOSE: To enable a clamping device to be operated manually and adjusted finely by making a guide groove formed in a rotatable disc curved extending across a larger rotating angle than a specific angle and thereby diminishing the degree of inclination of the guide groove. CONSTITUTION: Two small hole openings 19 are present alongside the longitudinally slender opening 15 of a swordlike saw part 12 and the protrusion part 21 of a U-shaped slider 8 is fitted into the small hole openings 19. In addition, the swordlike saw part 12 is provided on the curved part 22 of the slider 8 and a pin 9 is provided on the slider face of the opposite side. The pin 9 is engaged with a guide groove 5 extending in a curved shape in a rotatable disc 16. The guide groove 5 is formed in a curved shape extending across a larger rotating angle than 270 deg. (in the case of a practical example: 360-450 deg.) and therefore, the degree of inclination of the groove 5 is low. For this reason, the disc 16 can be manually rotated and the rotary movement of the swordlike saw part 12 can be adjusted precisely over the entire length of the groove 5. | ||||||
