Fluid discharge system and squeezer thereof

A squeezer, comprising:

• a pair of rolling shafts, a driving device and a mounting bracket,
• wherein the pair of rolling shafts being rotatably mounted to the mounting bracket, each rolling shaft having a mounting part at each end and a squeezing segment located between the mounting parts;
• the squeezing segment including a supporting shaft and an elastic body surrounding the supporting shaft;
• the pair of rollers being capable of operatively clamping an object to be clamped between the squeezing segments and oppositely being rotated by the driving device to apply a squeezing force to the object clamped, and
• the driving device including a motor, wherein the motor being mounted around the rolling shaft,
• wherein the mounting bracket comprises two first bases, a second base and a locking mechanism, wherein one end of the rolling shaft is rotatably mounted to the first base, the other end is rotatably mounted to the second base, and the locking mechanism is used to operatively lock or release the pair of rolling shafts.
