发明名称 Golf practice device
摘要 A golf practice device includes a solid golf ball which is mounted within a thin net of cords carried on the bottom end of a flexible cable. A spring connects to the top end of the cable to absorb the force when the ball is struck. The top end of the spring and cable assembly is supported to swing about the lower leg of a crank arm. The upper leg of the crank arm is supported for rotation on the frame of the device so that when the ball is hit the impact force is distributed between the cable and the crank arm. A pair of cord ends which hang below the ball drag on the ground to quickly stabilize the ball in hitting position for the next stroke.
