In order to achieve the above object, the utility model provides a kind of glof club head of automatic adjusting center of gravity, it is characterized in that: include half bar head, go out half ball cover in this half bar head is inner one-body molded, in the outside affixed scope of attack of this half bar head, be formed with a filling seat in this hemisphere cover bottom and communicate with the bottom of this half bar head;

In this second half ball cover of hemisphere cover combined outside, sealing is the spherical of a hollow between this two halves ball cover, and a hollow ball float is set between the two halves ball cover, is full of liquid in the two halves ball cover, and this hollow ball float is to be suspended on this liquid; Second half bar head of side secure bond in addition in this half bar head;

One leak-stopping steel ball is located at the top place of filling seat, and is screwed into place, filling seat bottom with a sealed screw and solid and seals, and is hollow form between two halves ball cover and two halves bar head.

The glof club head of described automatic adjusting center of gravity is characterized in that: this filling seat is the aperture greater than filling seat top in the aperture of bottom.

Via above explanation as can be known, the utility model have at least as after advantage:

1. can make the center of gravity of bar head be adjusted to best position of centre of gravity automatically, can reach preferable stability for shot.

2. simple in structure and by with half bar head (10) and hemisphere cover (11) and the integrated structure of filling seat (13), advantage firm in structure is arranged.

3. form two hollow forms between two halves ball cover (11), (21) and two halves bar head (10), (30), so can produce the batting sound in square stance.

4. quite simple and easy because of the utility model, and do not need to use the foaming body of commonly using to fix spherical in the space structure of integral body, suitable simple on fabrication schedule, the low advantage of cost is arranged.
