BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a racket frame, and more particularly to a racket frame that can provide an enhanced structure and reduce transmitted shock and vibration when used. [0003] 2. Description of Related Art [0004] With reference to FIG. 11, a conventional racket frame is used for playing with a tennis ball, a badminton ball or a paddleball and usually has a handle (5), a connecting segment (6) and a head hoop (7). [0005] The handle (5) has a proximal end and a distal end. [0006] The connecting segment (6) can be an inverted triangle shaped, a V-shaped or an arc-shaped, is connected with the handle (5) and has a throat (61) and two shafts (62). The throat (61) is connected with the proximal end of the handle (5) and made of plastic. The shafts (62) are respectively mounted with the throat (61). [0007] The bead hoop (7) is elliptical shaped, may be made of aluminum alloy or carbon fiber composite, is connected with the connecting segment (6) and has a bottom end, a top end, an inner surface, a yoke (72) and a string (71). The yoke (72) is formed on the bottom end of the head hoop (7), is mounted with the shafts (62) of the connecting segment (6) and made of plastic or carbon fiber composite. The top end is formed with the yoke (72). The string (71) is crisscrossed with the inner surface of the head hoop (7). [0008] However, the conventional racket frame has the following shortcomings. [0009] 1. If the head hoop (7) is made of aluminum alloy, the cost for manufacturing the conventional racket frame is low, but the strength, the shock absorbency and the weight of the conventional racket frame is weak and heavy, and this may result injuries to players. [0010] 2. In addition, if the head hoop (7) is made of carbon fiber and strong, light weight and can reduce the vibration damping and the shock, but the cost for manufacturing the conventional racket frame is high and increases the economical burden to the user. [0011] The invention provides a racket frame that can mitigate or obviate the aforementioned problems. SUMMARY OF THE INVENTION [0012] The main objective of the present invention is to provide a racket frame that can provide an enhanced structure aid reduce transmitted shock and vibration when used. [0013] The racket frame has a handle, a connecting segment and a frame. The connecting segment is inverted triangle shaped, is connected with the handle and has a throat and two shafts. The throat is connected with the proximal end of the handle. The shafts are respectively formed with the throat. The frame is hollow, is elliptical shaped, is made of aluminum alloy, is connected with the connecting segment and has a frame segment and at least one compound material tube. The frame segment has a yoke, a bottom segment and a string. The at least one compound material tube is made of carbon fiber, is attached to the bottom segment and each has a proximal end and a distal end.
