The auxiliary moving weight 50 is composed of a ring shape made of any kind of heavy material selected from metal, wood, rubber, resin.

Next, operations and effects according to the first and second embodiments of the present invention configured as described above will be described.

When the exerciser takes the swinging position by holding the grip part 30, as shown in FIG. 3, the moving weight 42 moves toward the grip part 30 along the shaft 10 by the weight of the self and the expansion force of the elastic member 44.

 At this time, when the bat swings, as shown in FIG. 4, the movable weight 42 moves rapidly along the shaft 10 toward the fixed weight 20 along the shaft 10 by its own weight and centrifugal force, and moves the movable weight 42 and the fixed weight 20. Pressurize (contract) the coil spring-shaped ballistic member 44 located between the () and at the same time the moving weight 42 collides with the fixed weight body 20 to generate a sound (hit sound).

Since the ball member 44 applied here has a structure in which the pitch is gradually narrowed from one side end in contact with the moving weight body 42 to the other end in contact with the fixed weight body 20, the swing speed is increased. Depending on the medicine, the elasticity (resistance) can be adjusted step by step.

For example, if the centrifugal force is much greater than the elastic force of the elastic member 44, the moving weight 42 strongly collides with the fixed weight 20 at a high speed to generate a strong sound (hit sound), and the centrifugal force is the elastic force If slightly larger than the moving weight 42 is generated in a different sound (propagation sound) in proportion to the impact force, such as a weak impact on the fixed weight body 20 at a low speed to generate a weak sound (hit sound).

However, if the centrifugal force is smaller than the elastic force of the elastic member 44, the moving weight 42 does not reach the fixed weight 20, so that no sound (hit sound) is generated.

And, since the swing swing exerciser can be adjusted to match the ability of the exerciser in accordance with the replacement of the high weight and resilient elastic member 44 of the moving weight 42 and the auxiliary moving weight 50 impact moment in the swing motion And practice can be exactly matched to the timing of the hitting moment in the actual hit, this practice repeated swing practice can increase the power and swing speed as well as strengthen the wrist strength.

That is, since the shaft 10 and the grip part 30 are screwed to correspond to each other so as to be detachable as shown in FIG. 6, for example, after the shaft 10 is separated from the grip part 30, the shaft 10 is moved to the rear side of the shaft 10. A swing that requires stronger power and faster swing speed when additionally combining the auxiliary moving weight 50 provided separately between the stopper 46 and the moving weight 42 or replacing the high elasticity ballistic member 44. It can be used as a exerciser, and this swing exerciser can not only cope with the pitcher's various pitches and fast fastballs in practice, but also improves the hit rate and hit power.

In addition, the elastic member 44 is because the elastic force can be adjusted according to the position adjustment of the stopper 46, the moving speed of the moving weight 42 and the auxiliary moving weight 50 according to the swing posture and swing speed of the exerciser, Complement the point that the centrifugal force is different by the starting point, weight, swing track, and the like.

On the other hand, since the luminous body 22 or the flasher 60 is attached to the outer circumference of the fixed weight body 20, the luminous body 22 or the flasher during the day and night as well as the sound of the impact moment (hit sound) during the swing practice While visually confirming the impact moment and trajectory through lights generated at 60, the hitting posture correction and the concentration of the hitting moment can be increased.
