Abstract

A corner head includes a driving body, a driven body, a bell crank, and a support pin. The driving body and the driven body both include a guiding portion. The bell crank includes first and second guided portions and is rotatable about the support pin. The guided portions are slidable within the respective guiding portions of the driving body and the driven body. When the driving body is moved in a first direction, the first guided portion is guided by the guiding portion of the driving body and moves in a second direction perpendicular to the first direction; the bell crank rotates about the support pin; the second guided portion is guided by the guiding portion of the driven body and moves in a third direction different from the second direction; and the driven body moves in a fourth direction perpendicular to the third direction.
