When the furniture assembled by the boards, such as a cabinet, is vertically connected between the boards, a three-in-one fastener is needed to connect the boards vertically and firmly. The existing three-in-one fastener comprises an embedded part, an eccentric wheel and a metal pull rod, wherein the embedded part is an internal thread sleeve, the embedded part is embedded on a horizontal plate, the axis of the embedded part is perpendicular to the horizontal plate, a mounting hole is formed in the bottom end of a vertical plate, a positioning hole communicated with the mounting hole is formed in the surface of the vertical plate, the axis of the positioning hole is perpendicular to the axis of the mounting hole, the eccentric wheel is installed in the positioning hole, the rod part of the metal pull rod is in threaded connection with the embedded part, and the head of the metal pull rod is located in an eccentric groove of the eccentric. Because the distance from the bottom of the eccentric groove to the axis of the eccentric wheel is gradually reduced along the rotation direction in the circumferential direction, the metal pull rod moves towards the axis of the eccentric wheel under the driving of the notch of the eccentric groove, namely moves upwards, so that the vertical plate is vertically and tightly connected with the horizontal plate.
Since the eccentric wheel is required to bear the pulling force from the metal pull rod, which is applied in the radial direction, in the existing three-in-one fastener, the applied sheet material must generate a supporting force to the eccentric wheel opposite to the pulling force of the metal pull rod, which results in that the three-in-one fastener cannot be applied to the hollow sheet material such as the honeycomb sheet material. The existing three-in-one fastener is only suitable for plates with certain density, namely the three-in-one fastener needs the circumferential direction of an eccentric wheel to obtain supporting force from the plates and prevents the eccentric wheel from moving downwards due to the pulling force of a metal pull rod.
