The first connecting piece, the second connecting piece and the plug body of this solution form an F shape when viewed from the side, and the bayonet formed by the first connecting piece and the second connecting piece can just include the thickness of the steel frame.
[0009] As a preferred solution of the utility model, the first connecting piece, the second connecting piece and the plug body are made in an integrated manner, and the second connecting piece is formed by separating and bending the middle part of the plug body. The first connecting piece of this solution can be formed by extending and bending the end of the plug body, and the second connecting piece can be formed by punching three through grooves in the shape of a gate from the middle of the plug body and then bending from the middle of the plug body.
[0010] As a preferred solution of the utility model, a side panel is provided on the inner side of the sofa armrest seat, and the buckle is fixed on the side panel.
[0011] As a preferred solution of the utility model, the buckle includes a trapezoidal plug-in base plate, both sides of the plug-in base plate are flanged upward to form slot side walls, the slot side walls are flanged toward the center of the plug-in base plate to form a slot baffle, the plug-in base plate, the slot side walls, and the slot baffle are combined to form a slot, and the plug-in base plate is fixedly connected to the side panels of the sofa armrest seat with bolts.
[0012] The insert buckle structure of the present invention can also be used to connect a sofa base and a sofa backrest. After the sofa base is connected to the sofa armrest and the sofa backrest at the same time, the entire sofa structure can be fixed and has sufficient stability.
[0013] Compared with the prior art, the utility model has the following beneficial effects: reasonable structure, simple operation, accurate positioning and good stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-3 As shown, the utility model provides the following technical solutions:
[0023] A plug-in piece for connecting a sofa armrest and a sofa base comprises a sofa armrest seat 1 and a sofa base 2. The sofa armrest seat 1 and the sofa base 2 are respectively provided with a plug-in piece 3 or a buckle 4, and the sofa armrest seat 1 and the sofa base 2 are connected to each other through the plug-in piece 3 and the buckle 4; one end of the plug-in piece 3 is connected to the side of the sofa armrest seat 1 or the sofa base 2, and the other end of the plug-in piece 3 is gradually narrowed and extended; one side of the buckle 4 is connected to the side of the sofa armrest seat 1 or the sofa base 2, and the buckle 4 is provided with a slot 5 that matches the shape of the plug-in piece 3.
[0024] The sofa base 2 is provided with a rectangular steel frame, and one end of the insert 3 is connected and fixed to the side of the rectangular steel frame.
[0025] The plug 3 includes a plug body 31, a first connecting piece 32 vertically connected to the plug body 31 is provided on the top of the plug body 31, a second connecting piece 33 vertically connected to the plug body 31 is provided in the middle of the plug body 31, one side of the rectangular steel frame is provided between the first connecting piece 32 and the second connecting piece 33, and the rectangular steel frame is fixedly connected to the first connecting piece 32 and the second connecting piece 33 with bolts.
[0026] The first connecting piece 32 , the second connecting piece 33 and the inserting piece body 31 are made in one piece, and the second connecting piece 33 is formed by separating and bending the middle part of the inserting piece body 31 .
[0027] A side plate 11 is provided on the inner side of the sofa armrest seat 1 , and the buckle 4 is fixed on the side plate 11 .
[0028] The plug buckle 4 includes a trapezoidal plug-in base plate 41, both sides of the plug-in base plate 41 are turned up to form a slot side wall 42, and the slot side wall 42 is turned toward the center of the plug-in base plate 41 to form a slot baffle 43.
