A novel connection structure for a woodware part, comprising: a bolt, a wooden nut, a round nail, a first woodware part and a second woodware part, wherein the first woodware part and the second woodware part are adjacently connected; wherein, the connection of the first and second woodware parts is realized by screwing the bolt into the wooden nut in an implanting hole of the contact surface of the second woodware part through a bolt hole on the contact surface of the first woodware part; wherein, the wooden nut and the round nail are used for fixing the wooden nut in the implanting hole of the contact surface of the second woodware part through an embedding hole and a nail penetration hole, the central line of the embedding hole and a central line of the implanting hole are perpendicular to and intersect with each other, and the central line of the embedding hole and the central line of the nail penetration hole on the wooden nut are overlapped; wherein the embedding hole extends through the second woodware part, a light source is placeable below the embedding hole of the second woodware part, wherein a fixing bolt is screwable in the wooden nut, a distance from an end of the fixing bolt to the central line of the nail penetration hole is greater than a distance from the central line of the embedding hole to the contact surface of the second woodware part, the wooden nut can be rotated until a diameter of a facula of the light source is equal to a diameter of the embedding hole, and the wooden nut can be fixed; and the embedding hole extends completely through opposing sides of the second woodware part. a bolt, a wooden nut, a round nail, a first woodware part and a second woodware part, wherein the first woodware part and the second woodware part are adjacently connected; wherein, the connection of the first and second woodware parts is realized by screwing the bolt into the wooden nut in an implanting hole of the contact surface of the second woodware part through a bolt hole on the contact surface of the first woodware part; wherein, the wooden nut and the round nail are used for fixing the wooden nut in the implanting hole of the contact surface of the second woodware part through an embedding hole and a nail penetration hole, the central line of the embedding hole and a central line of the implanting hole are perpendicular to and intersect with each other, and the central line of the embedding hole and the central line of the nail penetration hole on the wooden nut are overlapped; wherein the embedding hole extends through the second woodware part, a light source is placeable below the embedding hole of the second woodware part, wherein a fixing bolt is screwable in the wooden nut, a distance from an end of the fixing bolt to the central line of the nail penetration hole is greater than a distance from the central line of the embedding hole to the contact surface of the second woodware part, the wooden nut can be rotated until a diameter of a facula of the light source is equal to a diameter of the embedding hole, and the wooden nut can be fixed; and the embedding hole extends completely through opposing sides of the second woodware part.
