Patent Claims:	1. A composite baseball bat, comprising: a handle, said handle having a handle body and a tapered portion formed on one end of said handle body and gradually increased in diameter in direction away from said handle body; a spacer member formed of a soft material having a predetermined thickness, said spacer member being covered on the periphery of the tapered portion of said handle; a barrel sleeved onto said handle, said barrel having a first opening formed in a first end of a barrel body thereof, a second opening formed in a second end of said barrel body opposite to said first end and disposed in communication with said first opening, a tapered portion located on said first end of said barrel body around said first opening and pressed on said spacer member against the tapered portion of said handle; wherein said handle has a threaded portion disposed between the handle body and tapered portion thereof; the composite baseball bat further comprises a packing device set rotatably mounted on the threaded portion of said handle and stopped against a bearing portion at one end of said barrel around said first opening. 2. The composite baseball bat as claimed in claim 1, further comprising a knob fastened to an opposite end of said handle body remote from the tapered portion of said handle. 3. The composite baseball bat as claimed in claim 2, wherein said knob is fastened to the opposite end of said handle body by means of a screw joint. 4. The composite baseball bat as claimed in claim 1, wherein said handle is a hollow member having an open space extending through said tapered portion into the inside of said handle body. 5. The composite baseball bat as claimed in claim 1, wherein said packing device set comprises a nut threaded onto the threaded portion of said handle, and a packing ring sleeved onto said handle body and stopped between said nut and said bearing portion of said barrel. 6. The composite baseball bat as claimed in claim 1, further comprising an end cap capped on the second end of said barrel body of said barrel to seal said second opening. 7. The composite baseball bat as claimed in claim 1, wherein said handle has at least one rotation-prohibition means formed in the tapered portion thereof; said barrel has at least one rotation-prohibition means formed in the tapered portion thereof and matching the rotation-prohibition means of said handle to prohibit rotation of said barrel relative to said handle. 8. The composite baseball bat as claimed in claim 7, wherein each rotation-prohibition means of said handle extends to the end of the tapered portion of said handle remote from said handle body. 9. The composite baseball bat as claimed in claim 7, wherein each rotation-prohibition means of said handle is a plane located on the tapered portion of said handle. 10. The composite baseball bat as claimed in claim 9, wherein each rotation-prohibition means of said handle slopes at an angle equal to the sloping angle of the tapered portion of said handle. 11. The composite baseball bat as claimed in claim 9, wherein each rotation-prohibition means of said handle slopes at an angle different from the sloping angle of the tapered portion of said handle. 12. The composite baseball bat as claimed in claim 9, wherein each rotation-prohibition means of said barrel is a plane located on the tapered portion of said barrel. 13. The composite baseball bat as claimed in claim 7, wherein each rotation-prohibition means of said barrel is a plane located on the tapered portion of said barrel. 14. The composite baseball bat as claimed in claim 1, wherein said spacer member is a flat sheet member. 15. The composite baseball bat as claimed in claim 1, wherein said spacer member is a tapered ring. 16. The composite baseball bat as claimed in claim 15, wherein said spacer member is directly injection-molded on said handle over the tapered portion and a rotation-prohibition means of said handle. 17. The composite baseball bat as claimed in claim 1, wherein said spacer member is directly injection-molded on said handle over the tapered portion and a rotation-prohibition means of said handle. 18. A composite baseball bat, comprising: a handle, said handle having a handle body and a tapered portion formed on one end of said handle body and gradually increased in diameter in direction away from said handle body; a spacer member formed of a soft material having a predetermined thickness, said spacer member being covered on the periphery of the tapered portion of said handle; a barrel sleeved onto said handle, said barrel having a first opening formed in a first end of a barrel body thereof, a second opening formed in a second end of said barrel body opposite to said first end and disposed in communication with said first opening, a tapered portion located on said first end of said barrel body around said first opening and pressed on said spacer member against the tapered portion of said handle; wherein said spacer member is a tapered ring; wherein said spacer member is directly injection-molded on said handle over the tapered portion and a rotation-prohibition means of said handle; and wherein said handle has a plurality of holes cut through the tapered portion and a rotation-prohibition means of said handle for the filling of said spacer member. 19. A composite baseball bat, comprising: a handle, said handle having a handle body and a tapered portion formed on one end of said handle body and gradually increased in diameter in direction away from said handle body; a spacer member formed of a soft material having a predetermined thickness, said spacer member being covered on the periphery of the tapered portion of said handle; a barrel sleeved onto said handle, said barrel having a first opening formed in a first end of a barrel body thereof, a second opening formed in a second end of said barrel body opposite to said first end and disposed in communication with said first opening, a tapered portion located on said first end of said barrel body around said first opening and pressed on said spacer member against the tapered portion of said handle; said spacer member is directly injection-molded on said handle over the tapered portion and a rotation-prohibition means of said handle; and wherein said handle has a plurality of holes cut through the tapered portion and a rotation-prohibition means of said handle for the filling of said spacer member.
