Bearing, 25...Fixing bolt. Explanation of Figure 1: Arm 5 can change its inclination around joint 7, and can also make orbital movements. When the arm 5 is pulled down by hand or with the pull-down line 10 and then released, the spring 8 and the stopper line 9 are released.
Therefore, it will automatically return to its original state. The height of the suction cup 1 can be adjusted by changing the degree of slack in the tube 2, changing the hanging position of the stopper line 9, changing the inclination of the arm 5, and expanding and contracting the support column 4. Explanation of Figure 2, Suction cup 1 at the tip of tube 2
is connected. The figure shows the case where the ball is attached to suction cup 1 and set, and the case where the ball is released. By providing the suction cup 1 with a valve tongue that acts as a check valve, the vacuum device 3 can be used effectively. Explanation of Fig. 3: The rotating shaft 21 to which the arm 5 is attached rotates around the bearing 23 fitted in the joint casing 22, that is, the arm 5 swings. The joint casing 22 is fitted with a bearing 24 and rotates around the support column 4, that is, the arm 5 revolves around it. If you do not want it to rotate, tighten the fixing bolt 25.

Claims

[Claim for Utility Model Registration] A vacuum is generated from a vacuum device, the ball is attracted to a suction cup connected by a tube, and when the ball is struck, it separates from the suction cup and flies away. The suction cup is equipped with a valve tongue that acts as a check valve so that the suction port automatically closes to prevent a large amount of air from being sucked in if the ball is separated. When setting the ball, bend the tongue outward so it does not block the suction port. The height of the suction cup is adjusted using the tube, support column, arm, joint, etc. If the suction cup is too high to reach,
After tilting the arm with the pull-down line and releasing it after setting the ball, the spring automatically returns it to its original height. Moreover, the joint can rotate with respect to the support column, and the ball can also orbit. A ball hitting practice device having the above special mechanism and system.
