TECHNICAL FIELD

[0001] The utility model relates to furniture production technical field especially relates to a furniture connecting piece. BACKGROUND

[0002] Furniture refers to the indispensable appliance and facility category for human beings to maintain normal life, engage in production practice and carry out social activities. Many furniture needs to splice and assemble various boards in the production process, such as cabinets, storage boxes, writing desks, etc. When assembling, rivets or screws are often used to connect two components. This way is destructive to rod-shaped components, and will loosen after long-term use. In addition, for the connection between relatively thin boards, connecting through rivets is easy to damage the end of the board.

[0003] In the patent file with the publication number CN 217603097 U, a furniture connecting piece is disclosed, which includes an outer cylinder, a widened column is arranged at the middle part of the outer cylinder, a connecting column is arranged at the middle part of the widened column, a knob is threadedly connected to the top of the connecting column, a movable rod is inserted into the middle of the protective shell, a slope groove is formed in the outer wall of the movable rod, the movable rod penetrates through the connecting column, and a clamping block is arranged at one end of the movable rod; the clamping block is clamped on the first connecting piece, the outer cylinder is inserted into the second connecting piece, the knob is twisted to move the movable rod, and the first mounting piece and the second mounting piece are assembled together through clamping.

[0004] However, it should be noted that the outer cylinder is embedded in the second connecting piece, which is undoubtedly destructive to relatively thin boards.
