Claims

[Scope of utility model registration request]

In a device for releasably fixing a rotatable fixing member to a fixed member at an arbitrary angle, a groove is formed in the fixing member along a circular line centered on the rotation center of the fixing member, and the fixing member A plurality of brake plates made of high-strength flexible thin plates are fixed to the inside and outside of the above-mentioned, respectively, and a narrow space is formed in the opposing portion of the inner plurality of brake plates and the plurality of outer brake plates. An intermediate brake plate is formed on the groove and along the groove, and an intermediate brake plate is arranged between the inner and outer brake plates, and the fixed shaft is axially inserted into the shaft hole of the protrusion provided on the fixed member side. the fixed shaft is slidably fitted into the intermediate brake plate, the fixed shaft is disposed within the narrow space, the fixed shaft is fitted into the hole of the intermediate brake plate, a locking member is provided on the fixed shaft, and the locking member is disposed in the groove so as to be relatively movable along the groove, and the protrusion is disposed in contact with the upper surface of opposing portions of the inner and outer brake plates;
A lifting mechanism is linked to the fixed shaft, and the lifting mechanism can clamp and press the inner and outer brake plates and the intermediate brake plate between the protrusion and the locking member, and A universal parallel ruler characterized in that two brake plates are integrally joined by axial press-fitting through a spacer, and the plurality of outer brake plates are integrally joined by axial press-fitting through a spacer. Brake device in the head.
