Claims

[Scope of utility model registration request]

A first arm A1 having a base axis R1 at a starting end and a second axis R2 at a terminal end; a second arm A2 having a second axis R2 at a starting end and a third axis R3 at a terminal end;
There is a third arm A3 having a third axis R3 at the starting end, and a second arm A2 or a second arm integrally therewith.
Connecting rod A21 rotating around axis R2 and second axis R2
A first quadrilateral link device having a connecting rod A12 connecting the base axis R1 and a connecting rod A13 rotating around the base axis R1, and a third arm A3 or rotating around the third axis R3 integrally therewith. Connector A31 and 3rd
A second quadrilateral link device including a connecting rod A22 connecting the axis R3 and the second axis R2 and a connecting rod A23 rotating around the second axis R2, the connecting rod A23 or the second shaft R2 integrally therewith. Connecting rod A2 rotating around
31, the connecting rod A12 connecting the second axis R2 and the base axis R1
1 and a connecting rod A122 that rotates around the base axis R1. In a device that converts a quantity into a rotation amount around a base axis R1, a third axis R
3 is extended in the direction of the axis, and a pair of left and right handles are provided at both ends thereof, and a pivot shaft for rotating the third shaft R3 around the second arm A2 by the pair of handles is a second pivot shaft. A four-axis rotational displacement conversion mechanism characterized in that it is provided at the intersection of the arm A2 and the third axis R3, and is provided with means for converting the amount of rotation into the amount of rotation around the base axis R1.
