         2 . The slate connector of  claim 1 , wherein the positioning sleeve is also provided with a through-hole extending along an axial direction of the threaded hole, and a diameter of the through-hole is larger than a major diameter of the threaded hole. 
     
     
         3 . The slate connector of  claim 2 , wherein the positioning sleeve is provided with a top plate, a bottom plate, and a middle connecting portion fixedly connected between the top plate and the bottom plate;
 the oblong nut is mounted between the top plate and the bottom plate, and is configured to be fitted onto the middle connecting portion to form a cylindrical structure;   the top plate and the bottom plate are both oblong plates; and   the through-hole and the plurality of barbs are provided on the middle connecting portion.   
     
     
         4 . The slate connector of  claim 3 , wherein the middle connecting portion has a C-shaped cross-section, and the C-shaped cross-section forms the arc-shaped groove; and
 the middle connecting portion and the oblong nut are arranged along the axial direction of the threaded hole and are fitted with each other.   
     
     
         5 . The slate connector of  claim 3 , wherein a thickness of the top plate is less than that of the bottom plate. 
     
     
         6 . The slate connector of  claim 1 , wherein a center of the threaded hole coincides with a center of the oblong nut in a height direction of the oblong nut and a center of the oblong nut a width direction of the oblong nut; and
 two ends of the threaded hole are each provided with a chamfer.   
     
     
         7 . The slate connector of  claim 6 , wherein the plurality of barbs are arranged in parallel in a height direction of the positioning sleeve. 
     
     
         8 . The slate connector of  claim 6 , wherein the positioning sleeve is made of a plastic material through injection molding; and
 the oblong nut is made of a metal material; an outer surface of the oblong nut is configured to be antirust; and internal threads of the oblong nut are configured to be carburized and hardened.   
     
     
         9 . A pool table, comprising:
 a slate;   a cushion;   a table cloth;   a plurality of bolts; and   the slate connector of  claim 1 ;   wherein a plurality of oblong nut holes are provided on a bottom surface of the slate, and a plurality of bolt holes are provided on a side surface of the slate; and the plurality of bolt holes are communicated with the plurality of oblong nut holes in a one-to-one correspondence;   the cushion is provided with a plurality of via holes in one-to-one correspondence with the plurality of bolt holes;   each of the plurality of oblong nut holes is embedded with the slate connector in an interference-fit manner; the oblong nut of the slate connector is located on one side of the plurality of bolt holes, and the threaded hole of the oblong nut is opposite to and communicated with a corresponding one of the plurality of bolt holes; and   a screw rod portion of the bolt is configured to pass through a corresponding one of the plurality of via holes, the table cloth, and a corresponding one of the plurality of bolt holes in sequence to be threadedly connected with the threaded hole, so as to fixedly install the cushion on the slate.   
     
     
         10 . The pool table of  claim 9 , wherein a side in each of the plurality of oblong nut holes away from a corresponding one of the plurality of bolt holes is provided with a blind hole for accommodating an end of the screw rod portion; and the blind hole is coaxial with a corresponding one of the plurality of bolt holes.
