Claims

[Scope of Claim for Utility Model Registration] (1) A rotation adjustment mechanism consisting of a fixed side and a movable side, in which the fixed side is pressed against only one point in the circular direction and when tightened, the screw tightens vertically and generates torque. The rotation adjustment mechanism is characterized in that the shape of the pressure welding part is angled so that the shape of the pressure welding part is angled so that the pressure welding part is in close contact with the surface, and only one side is pulled. (2) When the fixed side is pressed in only one place in the circular direction, the screw is tightened vertically, and when the screw is tightened, the end of the screw hole on the pressure welding part hits the end of the screw exactly, and the pressure welding part Claim (1) characterized in that the upper part prevents the upper part from escaping to the outside during tightening to generate torque, and the positioning hole at the lower part of the pressure welding part is made small to improve positioning accuracy, and one side is only used for pulling. rotation adjustment mechanism. (3) In order to prevent the screws from escaping to the outside when the pressure welding part is tightened, rounded corners or chamfers are added to the sticking parts above and below the pressure welding part to prevent the screws from sticking against the pieces, and to prevent them from sticking due to deformation, thermal deformation, friction, etc. The rotation adjustment mechanism according to claim 1 or 2, characterized in that torque is stabilized by preventing fluctuations in torque due to changes in contact surface and contact area.
