发明名称 Golfing and batting aid
摘要 A golfing and batting aid is provided which enables a user to maintain a proper head position while executing the swinging of a golf club or baseball bat. The golfing and batting aid comprises a mouthpiece, a rigid support bar which is configured to extend away from the mouthpiece and towards the rear of the user's head and an inflexible connecting member which connects the rigid support element to the belt loop or waistband of a user. In operation, the user bites down on the mouthpiece and adjusts the connecting member such that it is sufficiently taut to prevent the user from moving his head while executing a swing.
