Abstract
A clamping apparatus includes a motor, a first cone gear secured to a shaft of the motor, and two clamping bodies attached to opposite sides of the motor. Each of the clamping bodies includes a second cone gear meshing with the first, a threaded post fixed to the second cone gear, a carriage threadedly connected with the threaded post, and a clamp arm fixed to the carriage. The motor rotates the first cone gear, and in turn the second cone gears and the corresponding threaded posts. With the rotation of the threaded posts, the carriages move towards or away from each other, whereby the clamp arms cooperatively acquire an object between the clamp arms, or release the object therefrom.
