Further, in order to increase the moment of inertia (MOI) caused by the striking, the present embodiment further places a weight 322 on the back 320 of the head body 302, for example. The weight 322 can be made separately from the head body 302, for example, or can be integrally formed with the head body. By using the weight 322, the error tolerance of the hitting ball can be increased, so that the user can more easily hit the ball, thereby improving the hitting effect. Based on the above, the present embodiment simultaneously combines the design of the above two embodiments, including extending the hollow design of the top surface (or side) of the head body to the bottom plate of the head body, so that the head body has greater elasticity when hitting the ball. The deformation is performed, and an elastic member is disposed on the head body to provide a better elastic recovery effect. Therefore, the golf club head of the present invention has at least the following advantages: (1) having a large elastic deformation, so that the contact time between the hitting ball and the striking panel can be prolonged to improve the hitting feeling and the ball control property. And can correct and improve the shot angle of the ball. (2) The elastic member helps to accumulate a large amount of elastic potential energy, and feeds energy back to the striking surface, so that the ball can obtain more kinetic energy, thereby increasing the hitting distance. (3) The counterweight can increase the moment of inertia caused by the strike to improve the tolerance of the ball when hitting the ball. Therefore, the user can easily hit the ball, thereby improving the strike effect and reducing the error rate. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any one skilled in the art can make some modifications without departing from the spirit and scope of the invention. Modifications and refinements, as 'the scope of protection of this invention is defined by the scope of the patent application.
