Abstract: A waist twister includes a base disk, a rotation disk rotatably mounted on the base disk, a top disk secured on the rotation disk, a drive motor secured on the top disk and having an impeller, and a top cover secured on the top disk to cover the impeller. Thus, the impeller has an unevenly distributed weight on the drive motor, so that when the drive motor is operated to rotate the impeller, the drive motor produces a vibration to vibrate the top disk, the rotation disk and the base disk to provide a swaying function to the user standing on the top disk. In addition, the top cover has ventilating holes to introduce the air flow produced by the impeller to flow outwardly to provide a heat dissipation effect to the user.

Abstract: A golf club includes a shank, a grip portion, and a head portion. Thus, the head portion is provided with a first hitting face and a second hitting face, so that the user can use the head portion to hit the golf ball from the right side or the left side of the head portion. In addition, the first hitting face and the second hitting face of the head portion are used to move the golf ball outwardly from the obstruction no matter when the golf ball is located at the right side or left side of the obstruction, so that the user can move the golf ball outwardly from the obstruction easily and quickly without having to replace another golf club.

Abstract: A baseball practicing apparatus includes two opposite upright frames, two opposite longitudinal rods mounted between the upright frames and provided with a plurality of first emitters and a plurality of first receivers respectively, and two opposite transverse rods mounted between the upright frames and provided with a plurality of second emitters and a plurality of second receivers respectively. Thus, the pitching position of the baseball is detected exactly by provision of the emitters and receivers, so that the user can judge and calibrate the pitching position of the baseball, thereby facilitating the user practicing the pitching skill. In addition, the baseball practicing apparatus detects and displays the pitching position and the velocity of the baseball simultaneously, thereby enhancing the amusement effect.

Abstract: A football playing table includes a platform, a plurality of doll players, an artificial sod, and a ball. The artificial sod is located between the bottom plate of the platform and the ball to increase the height of the ball relative to the bottom plate and each of the doll players. Thus, the foot toe of each of the doll players and the ball has a relatively lower contact point, so that when the foot toe of each of the doll players hits the ball, the ball is kicked outward and upward to form a higher ball, thereby greatly enhancing the amusement effect of playing the table football.

Abstract: A basketball frame structure includes a backboard, two fixing plates, a base, two first upright rods, two second upright rods, two first links, an adjusting bar, two second links, and a plurality of hollow weights. Thus, the height of the backboard is changed by movement of the adjusting bar, thereby facilitating a user adjusting the height of the backboard. In addition, when the adjusting bar is moved, the positioning bolt is slidable in the slideway of the adjusting bar and detachably locked in either one of the retaining slots of the adjusting bar, so that the height of the backboard is changed in a multi-stage manner so as to fit requirements of different users.

Abstract: A playing table includes a transparent base plate, four foot stands mounted on the corners of the base plate and each having an upper end having a side formed with a through hole, and four light emitting members each mounted in a respective one of the foot stands and each aligning with the through hole. Thus, each of the light emitting members emits a light source passed through the through hole of a respective one of the foot stands and projected onto the base plate, so that the playing table has a light emitting effect, thereby enhancing the aesthetic quality of the playing table.

Abstract: A golf practicing device includes a rotation disk, a cover, a bar, and an adjusting knob. The golf practicing device has a height adjustable function. Thus, the height of the practicing ball of the bar can be adjusted arbitrarily so as to fit users of different heights and statures, thereby facilitating the users operating the golf practicing device.

Abstract: A golf practicing device includes a housing, an electromagnet mounted in the housing, a cover rotatably mounted on the housing, a magnetic block secured on the cover and aligning with the electromagnet, and a bar mounted on the cover for rotating the cover when the bar is hit. Thus, the energized electromagnet produces a magnetic force to magnetically attract and move the magnetic block to return the bar to the original position, so that the bar can be restored to the original position automatically, thereby facilitating the user practicing the golf skill.
