[0002] Furniture panel connectors are used to connect furniture panels. Panel connectors are currently widely used furniture panel connectors. Existing furniture panel connectors are mainly divided into two types: expansion type and fastening type. When the expansion type connector is working, the connecting rod is displaced under the pull of the eccentric wheel, and the connector head will expand outward, so that the undercut teeth on the outside of the connector head are clamped on the inside of the panel. The structure of the traditional expansion type furniture panel connector has two major technical defects;

[0003] For example, the authorized patent with publication number CN215861137U (hidden elastic furniture panel connector): it includes a shell, a connecting rod arranged in the shell, and a rotatable elastic cam assembly arranged on the connecting rod. The shell is provided with a first outer buckle and a second outer buckle respectively located in the plate A and the plate B, and the connecting rod is provided with a first expansion part and a second expansion part. The first expansion part is matched and connected with the first outer buckle, and the second expansion part is matched and connected with the second outer buckle. The hidden elastic furniture panel connector of the utility model has high connection stability, good reliability, fast installation speed, and strong fault tolerance.

[0004] The above-mentioned connecting parts of the prior art are set as an integral type, which makes the assembly between furniture panels inconvenient. Generally, one end is fixed by threading and the other end is assembled by inlaying. The locking of the end of the inlay assembly is not firm enough and is easy to fall out of the hole. The connection process requires pre-reserved holes in the furniture panels, and self-drilling holes are not possible, so the installation and fixation are not convenient. Utility Model Content

[0007] In a further embodiment, the first self-tapping screw and the second self-tapping screw are both provided with self-tapping heads at their ends, and demolition metal heads are provided at the end points of the self-tapping heads.

[0008] In a further embodiment, the end of the first self-tapping screw is connected to the connecting head via an adjusting handle, the bottom end of the adjusting handle is rotatably connected to the connecting head, and the top end of the adjusting handle is fixedly connected to the first self-tapping screw.

[0009] In a further embodiment, a screw head is provided at the bottom end of the connecting head, and the screw head is threadedly fixed to the threaded hole in the middle of the bidirectional connecting sleeve.

[0010] In a further embodiment, six anti-slip teeth are provided on the outer side of the bidirectional connecting sleeve, and the anti-slip teeth are connected to the side of the bidirectional connecting sleeve.

[0011] In a further embodiment, the width of the adjustment handle is the same as the width of the external thread on the outer side of the first self-tapping thread, and an anti-slip layer is provided on the outer side of the adjustment handle.

[0012] In a further embodiment, the second self-tapping screw is fixed to the bidirectional connecting sleeve by threads, the second self-tapping screw is entirely tapped into the B plate, and the first self-tapping screw and the bidirectional connecting sleeve are connected by threads.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
