[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] See also Figure 1-3A layer board splicing connector shown includes a right-angle connector 1 and two connecting rods 2. The connector 1 has an expansion end 11 and a connecting end 12. The expansion end 11 is provided with a penetrating connecting screw hole 111 and at least two expansion blocks 112 that can expand outward. The connecting rod 2 is screwed to the connector 1 through the connecting screw hole 111, and the expansion block 112 expands outward. The connecting end 12 is provided with a connecting hole 121 for the connecting rod 2 to pass through and a limiting medium 122. One end of the connecting rod 2 is located in the connecting hole 121 and abuts against the limiting medium 122. The limiting medium 122 can limit the connection rod 2 from being separated from the connecting end 12.

[0023] The connecting rod 2 includes a connecting screw rod 21 and a connecting straight rod 22. The connecting screw rod 21 corresponds to the connecting screw hole 111, and the connecting straight rod 22 corresponds to the connecting hole 121. A positioning medium 221 is provided on one end of the connecting straight rod 22 in the connecting hole 121, and the positioning medium 221 abuts against the limiting medium 122. The rod body diameter of the connecting straight rod 22 is smaller than the connecting hole 121, and the diameter of the positioning medium 221 is larger than the connecting hole 121.

[0024] An undercut thread 113 is provided on the surface of the expansion end 11 to increase the connection firmness. The connector 1 is integrally formed.

[0025] The eccentric lock wheel 3 is also included. The eccentric lock wheel 3 is provided with a bayonet 31. A connector 222 is provided on one end of the connecting straight rod 22 extending outward. The connector 222 corresponds to the bayonet 31, so that the connecting straight rod 22 and the eccentric lock wheel 3 are connected together. The width of the bayonet 31 is larger than the diameter of the connecting straight rod 22, and smaller than the diameter of the connector 222. The outer edge surface of the eccentric lock wheel 3 is provided with a tooth pattern 32 for increasing friction.

[0026] There is an inclined plane 4 at the right angle of the connector 1 to correct the angle deviation during installation

[0027] During specific use, a reserved hole is made on the 45° layer board, and then the expansion end 11 on the connector 1 is inserted into the reserved hole, and the connecting screw 21 is screwed in from the connecting screw hole 111 to make the expansion block 112 expand in the reserved hole, thereby achieving the purpose of locking. The connecting end 12 of the connector 1 and the connecting straight rod 22 are inserted into the reserved hole of another 45° layer board, and the two layers are spliced ​​neatly. Finally, the eccentric locking wheel 3 is used to connect with the connecting straight rod 22 accordingly. The eccentric locking wheel 3 can be rotated to lock the connecting straight rod 22 in the layer board, and when the eccentric locking wheel 3 pulls the connecting straight rod 22, the connecting straight rod 22 will also cause the connecting end 12 of the connector 1 to expand slightly, thereby enhancing the pulling force and preventing the connecting straight rod from withdrawing after the eccentric locking wheel is loosened.

[0028] One end of the connector 1 of the utility model is firmly connected by expansion, and the other end is conveniently connected by an eccentric locking wheel 3, so that the splicing of 45° plywood is more convenient and flexible, and the practicability is high.
