Abstract
A toggle-type positioning platform including a first platform, a motor, a screw rod, a second platform and a linkage is provided. The motor and the screw rod are disposed on the first platform; the motor is coupled to the screw rod and suitable for driving the screw rod to rotate. The second platform is above the first platform and is suitable for moving back and forth alternately along a predetermined path, wherein an included angle exists between an extended direction of the predetermined path and the screw rod. The linkage is disposed between the first platform and the second platform, and is connected between the second platform and the screw rod. The linkage is driven by the rotation of the screw rod, to drive the second platform to move along he predetermined path. Accordingly, the positioning precision of the toggle-type positioning platform is enhanced.
