Multifunctional connector used for building block connection

The invention discloses a multifunctional connector used for building block connection. The multifunctional connector comprises a fixing tube, and multiple through-connection holes are formed in the side wall of the fixing tube; one end of a connecting part is fixed inside one through-connection hole. By the adoption of the technical scheme, the problem is solved that in the prior art, a beam structure is adopted for connecting, and as a result many limits are generated; through the structure that the through-connection holes are formed in the side wall of the fixing tube, the connecting partis installed inside one through-connection hole, connection can be realized through the connecting part, two tube openings of the fixing tube and other through-connection holes can be connected, in this way, the multifunctional connection mode of the connector is realized, splicing is more flexible, and the diversity of building block splicing is improved. 本发明公开了种用于积木连接的多功能接头，其中，包括固定管，所述固定管侧壁开设有多个转接孔；连接件的端部固定在转接孔内。由于本发明采用
