Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to golf clubs, particularly golf clubs having double-layered trenches. [Prior Art] Generally, a concave groove is provided on the hitting surface of the golf club head. The main purpose of the line groove setting is to reverse the ball to be ack spin. "This can reduce the ball after landing. The rolling distance to improve the ball control. However, since the hitting surface does not deform and the ball stays on the hitting panel for a short time, the power to reverse the ball is completely caused by the direct friction between the groove and the ball, and the lateral direction of the groove and the ball surface is utilized. The friction causes the ball to reverse. The result of the 5th iron shot at the mechanical arm hitting speed of 75 mph can produce about 5800 rpm, the total distance is ι84 yards, and the rolling distance is 9 yards. Although this structure has its basic functions, The effect on ball control is still not ideal. In addition, as disclosed in Bulletin No. 439513, "The hidden head groove structure of the golf club head hitting surface", the case reveals the concept of the hidden trench. The deformation of the hitting panel increases the ball to stay on the hitting panel. The time, but the hitting panel of the case does not correspond to the hidden trenches for structural disclosure or setting, so the elastic effect of the deformable bounce panel after the deformation can not be multiplied, and The outer wire groove cooperates to increase the biteness of the hitting panel. 201103608 [Description of the Invention] The object of the present invention is to provide a golf ball of the same age (four) type groove. The structure of the double-layered groove can make the hitting panel produce less deformation during the ball hitting to increase the hit of the ball after hitting the ball. Reverse speed. In order to achieve the above object, the golf club head of the double-layered trench of the present invention comprises a head body having a groove at a position of the ball striking face, and a plurality of grooves are protruded from the bottom wall of the groove The support portion is formed to form a plurality of inner wire grooves; a ball striking panel is provided with a plurality of outer wire grooves on the front surface, and the ball striking panel is embedded and fixed at a position of the groove of the head body, and the back surface thereof abuts against the top ends of the support portions. [Embodiment] Hereinafter, an embodiment will be described in detail with reference to the drawings. As shown in the first and fifth figures, the same structure can be applied to the wood in the state of the iron head. The golf head of the double-layered trench of the present invention includes: a head body ίο, the head body is provided with a groove 11' at the bottom surface of the groove at the bottom surface of the groove The plurality of support portions 12 are convexly formed to form a plurality of inner wire grooves 13 which may be arranged in a lateral arrangement or may be arranged in a longitudinal or different angle arrangement, as shown in the fifth figure, and the adjacent two supports The distance between the portions 12 may be equal or unequal. In the present embodiment, the arrangement is illustrated in a lateral arrangement, and the adjacent two support portions 12 have the same separation distance. a ball striking panel 20, the batting panel can be made of materials such as Taman, stainless steel, MAZING 201103608 effect steel (MARAGING) or titanium alloy, and the front surface of the batting panel is provided with a plurality of outer grooves 21, the outer lines The grooves 21 may be arranged in a laterally aligned manner, or may be arranged in a longitudinal arrangement or at different angles. In the present embodiment, the grooves are arranged in a lateral arrangement. The ball striking panel 2 is embedded in a position fixed to the groove of the head body 10, the back surface thereof abuts against the top end of the supporting portion 12, and the outer peripheral grooves 21 of the ball striking panel 2 are recessed. The bottom wall of the groove 11 protrudes from the lower recess of the corresponding two supporting portions 12, that is, the position of the inner groove 13, so that the hitting panel 2 is supported by the portion of the supporting portion I2. The force is not deformed, and the portion that is not held by the support portion 12 can be deformed because there is no supporting force. The ball striking panel 2 is readable or brazed or miscellaneous or glued, or the like, or the two or three methods described above are fixed to the head body. With the above structure as shown in the fourth figure, the ball striking panel 2 of the present invention is provided with an outer groove 2 on the surface of the hitting panel of the prior art, and the wire is configured to increase the miscellaneous of the hitting panel and the ball. However, in hitting the ball (c means the ball), the panel is deformed at a portion that is not subjected to the cut portion 12 to increase the ball control. And because the head body 1〇 is biased by the support portion 12 to the ball striking panel 20, and the ball striking panel 2〇 is used to invert the ball through the outer wire grooves 21, the branch portion I2 is opposite The force application point A of the ball striking panel 2〇 and the position of the ball striking panel 2〇 front outer line groove 21 and the ball point b of the ball do not overlap, and the baffle panel is deformed and rebounded between the two positions A and B. When the reply is generated, a torque is generated, so that the reverse rotation speed after the ball is hit can be increased. The result of the invention is also that the 5th iron is used to test the speed of the robot arm at a speed of 75 mph, and the ball reversal speed can be increased to about 201103608. Qing's total distance is 155 stone horses, and the distance of the ball rolling is 3 yards. It is obvious that the structure of the invention is superior to the conventional d-line _ head head in the ball control property, which meets the requirements of precise ball control. Types Although the description is based on irons, the use of a club head should not be ruled out. ~ [Simple description of the drawings] The figure is an external view of the present invention.
