Claim Text:
1. An optical fiber rotary squeezer polarization controller, comprising a base, a left bracket and a right bracket respectively mounted at both ends of the base, wherein a shaft is rotatably mounted between the left bracket and the right bracket, the shaft having a through channel cut therein lengthwise for placement of an optical fiber without fiber twisting, the shaft further being mounted with a squeezing apparatus corresponding to the channel, wherein the squeezing apparatus includes an upper cover, an optical fiber clamp and an adjusting knob, the adjusting knob being disposed in the upper cover which is in turn fixed onto the shaft, the optical fiber clamp being squeezed towards or moved away from the channel under the control of the adjusting knob, wherein the squeezing apparatus further includes a spring which is disposed between the adjusting knob and the optical fiber clamp, the adjusting knob varying strain of the spring thereby varying a pressure applied on the optical fiber clamp, and wherein the squeezing apparatus still further includes a steel ball which is disposed between the adjusting knob and the spring, the adjusting knob controlling strain of the spring via the steel ball.
