The invention discloses a bouncing collision bead type reaction speed trainer, which is characterized by comprising a base; a left side plate and a right side plate in opposite are connected to the base; three elastic ropes are connected to the middle of the left side plate and the right side plate, and the middle part of every elastic rope is connected with a collision bead; gravities of three collision beads are located on the same plane, and both ends of the three elastic ropes are formed to be three connecting points on the left side plate and the right side plate; the connection line of three connecting points at the same side is an obtuse triangle. When the bouncing collision bead type reaction speed trainer is in use, three elastic ropes are stretched by the left and right side plates to tighten, and three collision beads are located in the same plane, thus trainings with different difficulties can be practiced through multiple methods; after collision, the collision is transferred, and multiple collision transfer modes can be arranged to meet the training with higher difficulty; the trainer is not limited by the field, the training load is small, thus the reaction speed and the opportunity judging ability are improved, the relationship between speed and force in the movement can be learned; the bouncing collision bead type reaction speed trainer, used for training out of actual training, is significant in effect.
