Abstract:
A cue shaft with ball control enhancement function and a billiard cue thereof are provided. The cue shaft includes an outer tube and a combine end. The outer tube includes a strike end and a combine end disposed in opposite to the strike end, with a housing space formed between the strike end and the combine end. The housing space is disposed along an axial direction of the outer tube. The combine end is configured to be combined with the cue butt. The inner member has a length and is disposed in the housing space, such that an outer edge of the inner member fits an inner edge of the outer tube. Therefore, with the cue shaft not being a singular component, the ball controlling stability is improved, thus achieving an optimal ball striking performance.

Claim (Index 1):
A cue shaft with ball control enhancement function, which is combined with a cue butt of a billiard cue, the cue shaft comprising:\n an outer tube comprising a strike end and a combine end disposed in opposite to the strike end, with a housing space formed between the strike end and the combine end, the housing space being disposed along an axial direction of the outer tube, and the combine end being configured to be combined with the cue butt, the outer tube being a combination tube formed of a plurality of wooden components arranged around an axial direction of the cue shaft, and the components being connected in a side-by-side manner, such that the outer wall of the outer tube formed by the components presents a smooth peripheral wall along the axial direction of the cue shaft without step structures thereon; and an inner member having a length and disposed in the housing space and placed away from the combine end, an outer edge of the inner member and an inner edge of the outer tube having a sectional face formed in a circular shape, such that an outer wall of the inner member is fully surrounded by the outer tube.
