1, right-angle tenon joint: tenon shoulder surface and tenon cheek surface are perpendicular to each other or basically perpendicular. The joint is firm and reliable, and the machining difficulty is relatively low, so it is the most widely used tenon joint form.

2. dovetail joint joint: Its tenon is trapezoidal or semi-conical with big end and small root, which is firm and tight, but it is difficult to process and assemble. Used for corner joint of box and frame parts in solid wood furniture (such as corner joint of cabinet, corner joint of drawer, etc.). ).

3. Round bar tenon joint: It is a cylindrical tenon. It has the advantages of simplified processing technology, easy assembly, material saving and suitability for mass production.

However, the bonding strength and stability are relatively poor. In frame structure, tenons can be used for the connection of frames, while in plate structure, tenons can be used for the fixed connection and positioning between plates.

4. Comb-tooth tenon joint: also called finger tenon, its shape is similar to comb teeth (or fingers). Mainly used for the extension of short materials, such as the extension of square materials and plates, and the splicing of bent parts.

5. dovetail joint connection: Among many mortise-and-tenon structures, dovetail joint connection is recognized as the strongest mortise-and-tenon connection mode, and it is also the strongest connection mode connecting the two ends of the wood board.

This tenon joint has some very important advantages, such as ensuring the integrity of furniture when wood expands or contracts. The traditional dovetail joint adopts the combination of wide dovetail head and narrow plug joint, and the dovetail head is made on the horizontal part.
