Description
Technical field
A kind of bat, more particularly to a kind of baseball bat with shock-absorbing and intensity.
Background technology
The bat that general baseball uses is made with single material, is probably divided into the classes such as wooden bats and aluminum bat.
Aforementioned such bat respectively has excellent, disadvantage, wherein and the advantages of wooden bats is to keep striker more comfortable in the feel of batting,
And it is cheap to peddle valence, but wooden bats disadvantage one is heavier-weight, striker is relatively slow and painstaking in speed of swinging so that waves
Ball that stick is hit is not powerful enough, flying distance is again short；The two is that wooden bats structure is fragile, and rhegma is easy after swinging
Even fracture；Furthermore it is that wooden bats generated vibrations when hitting sphere are big, striker's hand is made to feel tingle or even make
At injury.
And although the weight of aluminum bat is better than the light-weight and intensity of wooden bats, the disadvantage is that square stance, aluminium
The driving part of the ball-making bar power that catches a packet will appear dent, and striker's hand can experience vibrations when holding by the grip part, more have
It is notably the sound of shots and reverb that can send out shrillness.And it is another can not improve, entire wooden bats and aluminum ball
Both sticks are not easy to grasp using same material.
So how effectively to improve shock-absorbing and the intensity effect of existing wooden bats and aluminum bat, and weight can be mitigated
Amount ensures and is promoted that real dealer always actively studies the target of improvement.
