Prevent distortion, prevent tensile tenon fourth of twelve earthly branches device and furniture

The utility model belongs to the technical field of woodwork manufacturing. For solve the limitation that traditional tenon fourth of the twelve earthly branches structure was used in furniture, the utility model provides a preventing the distortion, preventing tensile tenon fourth of the twelve earthly branches device, it includes tenon and tongue -and -groove, inside the tenon is located the tongue -and -groove, and its characterized in that: fixed glue is packed to the degree of depth and width that tenon length in the tongue -and -groove and width are lighter than the tongue -and -groove in the space between tenon and tongue -and -groove. Provide a furniture that utilizes this tenon fourth of the twelve earthly branches device preparation simultaneously. Should prevent the distortion, prevent that tensile tenon fourth of the twelve earthly branches device had both had the advantage of traditional tenon fourth of the twelve earthly branches structure, solve traditional tenon fourth of the twelve earthly branches structure simultaneously again at the technical problem who receives tenon fracture under the efforts such as distortion, drawing, drops.
