What Wikipedia says

The stretch reflex (myotatic reflex), or more accurately muscle stretch reflex, is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints.
