Disclosed is a juice extraction module for a juicer, which includes a container formed with a juice discharge port； a sieve positioned inside of the container； a screw positioned inside of the sieve to extract juice from a material； a lid coupled to a top end of the container and formed with an input portion through which the material is input； and a safety cover rotatably installed to a main input opening of a top end of the input portion to be movable between a first position and a second position. The safety cover includes a first cover portion erected to open the main input opening in the first position and closing the main input opening in the second position； and a second cover portion formed integrally with the first cover portion, the second cover portion moving the safety cover to the second position when the second cover portion is pushed by a downward applied force from the first position, whereby the first cover portion blocks the main input opening.
