Claims

[Claims for Utility Model Registration] A device body and a pair that engages with a fixed shaft fixed to the device body through elongated holes and can approach and separate from each other along a first straight line orthogonal to the axis of the fixed shaft. a claw mount, a drive member held in the device body so as to be movable in a direction perpendicular to the first straight line, a drive device for moving the drive member, and one end of each of which is attached to each of the claw mounts. , each fixed member is connected rotatably around a first axis of rotation perpendicular to the first straight line and a plane parallel to the first straight line and the moving direction of the driving member, and each other end thereof is attached to the driving member. perpendicular to a second straight line that is perpendicular to the axis of the shaft and parallel to the moving direction of the driving member;
and a pair of first links rotatably connected around a second rotational axis parallel to the first rotational axis and having equal lengths, each one end of which is rotatable about the fixed axis. The other end portions of the first link are connected to each other, and each other end portion is located at the midpoint of the straight line connecting the first rotation axis and the second rotation axis of the first link, and around a third rotation axis parallel to the rotation axes. a pair of second links rotatably connected to and having equal lengths.
