发明名称 Batting practice device
摘要 A batting practice device for use by a person acting as a pitcher and another person acting as a batter. A pole has a first end placed on the ground and a second end held substantially vertically. The pole is longer than the height of the pitcher, but is not permanently mounted in the ground. The pitcher prevents substantial movement of the first end of the pole by placing a foot in an anchoring loop provided at the first end of the pole. A line is operatively attached, via a freely rotating mount, to the second end of the pole. The line has a swivel connection to prevent twisting of the line. The line is operatively connected to a ball via a ball harness. The ball harness has two straps sewn together, with the ends of the respective straps having loops for receiving one end of the line. Various sizes of conventional balls can be easily inserted and removed from the ball harness.
