     FIELD OF THE INVENTION 
     The present invention relates generally to a training device of golf, and more particularly to a device for training the ball-hitting posture of a golfer. 
     BACKGROUND OF THE INVENTION 
     The conventional golf training devices are generally defective in design in that they can not be used to train the stance of a golfer in such a way that the golfer assumes a correct bodily posture to hit the golf ball with a golf club. In order to be a skillful golfer, a golfer, especially a beginner, must practice repeatedly for the purpose of acquiring proficiency in the ball-hitting posture. 
     BRIEF SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a device which is exclusively designed for training the ball-hitting posture of a golfer. 
     In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a training device, which comprises an arcuate track and a support frame for supporting the arcuate track on a surface. The arcuate track is provided in one longitudinal side with a guide wall for guiding the golf club head to move in a path. 
     The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in FIGS. 1 and 2, a training device embodied in the present invention comprises an arcuate track  10  and a support frame  30  which is used to support the arcuate track  10  on a surface. The arcuate track  10  has a track surface  11  corresponding in length to a maximum range in which the golf club head swings in the course of driving off a golf ball. The track surface  11  is provided in one longitudinal side with a guide wall  12  for guiding the moving of the head  21  of a golf club  20 . The arcuate track  10  is integrally made. 
     The support frame  30  comprises a base  31 , and an expandable rod  32  by means of which the inclination of the arcuate track  10  is adjusted, as illustrated in FIG.  7 . 
     The arcuate track  10  is provided with a series of locating holes  16 , which are used to accommodate legs  41  of a defining piece  40 . The defining piece  40  is used to define the range of movement of the head  21  of the golf club  20  along the arcuate track  10 , as illustrated in FIG.  5 . 
     As shown in FIG. 6, the arcuate track of the present invention is formed of a plurality of arcuate segments  101 , each being provided with a guide wall and a series of locating holes  16 . The arcuate segments  101  are joined together end to end to form the arcuate track  102 . The joining of the arcuate segment and a mortise  14  of one end of another segment, as shown in FIG.  6 . The tenon  13  is held securely in the mortise  14  in conjunction with a pin  15  which is retained in a hole  130  of the tenon  13  via a through hole  140  of the mortise  14 . 
     The present invention is versatile, as illustrated in FIG. 10 in which a circular track  102  of the present invention is used to hold a ball trap  51  and a target  52 . The circular track  102  is mounted on a frame  53 . The ball trap  51  and the target  52  are fastened with the circular track  102  by cords which are put through holes  120  of the guide wall  12  of the track.
