The specific embodiment

Below in conjunction with the drawings and specific embodiments to this novel being described in further detail.

As Fig. 1～shown in Figure 6, it has disclosed the preferable concrete structure in the present embodiment, a kind of golf club of using Venturi effect raising rebound coefficient, comprise top cover (Crown) 1, base plate (sole) 2, groove filling working of plastics (TPU) 3 and the scope of attack (face) 4, the inner hollow structure of golf club, described top cover 1 and base plate 2 are being provided with groove 5 respectively near scope of attack place, and described groove 5 is provided with perforation 51 in the bottom.

Preferably, described perforation 51 is positioned at the centre of bottom portion of groove, and the width of perforation is 1mm-5mm.

Groove filling working of plastics uses special binder that sealing groove is carried out in the bottom of groove, makes groove filling working of plastics can firmly be fixed on sealing perforation simultaneously 51 in the groove.

Further, the bottom portion of groove 53 of base plate can be surperficial near parallel (as Fig. 1) or vertical (as Fig. 2) with top cover 1 with the bottom portion of groove 52 of backplate surface, top cover, its angle is 0～20 ° or 70 °～90 °, and decide on the structural design of bulb inside at its angle of inclination.
