Claims

[Scope of utility model registration request]

Rotation of the intermediate part between a stationary plate that has a rotating plate fitting part with a cylindrical outer periphery through which a non-cylindrical support installed in a practice area aligns, and another stationary plate that is closely fixed to the end surface of the rotating plate fitting part. A rotary disk is fitted onto the outer circumferential surface of the plate-fitting part, and a ball is attached to the outer circumferential surface of the disk via a ball arm, and a spring for restoring the original state is fitted inside, and the other end of the spring is engaged. A fixed plate on the opposite side of the fixed plate is provided with an annular groove surrounding the tightly fixed part and having a narrowed part in a part, and a stopper with a shock absorbing spring is interposed in the annular groove,
On the other hand, a notch in the form of a partial wall that can pass through the narrowed part of the annular groove is formed on the sliding surface of the rotary disk, and these fixed plates and the rotary disk in between are formed as one body, and the height of the erected support is adjusted appropriately. It has a structure that is fixed in position,
When the ball is hit, the notch on the sliding surface of the rotary plate goes around the annular groove of the fixed plate and passes through the narrowed part.
The impact of the impact is then absorbed by the second rotation of the ball arm by propelling the stopper to make one more rotation, and the ball arm returns to its original state by the restoring force of the subsequent spring. A batting practice machine.
