In the above description, as a preferred solution, the left and right sides of the roots and ends of the first dovetail and the second dovetail are provided with stepped tension surfaces. Since the first dovetail and the second dovetail have a symmetrical structure, the tension surface is also a symmetrical structure. The tension surface with a stepped structure is designed to make the dovetail have a pulling force and be more stable after installation.

In the above description, as a preferred solution, the bottoms of the first dovetail and the second dovetail are both provided with stepped support surfaces. Its stepped support surface is also used to make the dovetail tenon have a pulling force.

In the above description, as a preferred solution, the bottom surface of the root of the first dovetail and the second dovetail is shorter than the bottom of the end, and gradually increases from the bottom of the root of the first dovetail and the bottom of the second dovetail along the direction of the bottom of the end. increase. The bottom of the dovetail is designed to be arc-shaped and the top is large and the bottom is small. For the convenience of installation, it adopts a drop-type structure to be directly aligned and installed.

The connector of the utility model can be connected at any angle from 30 to 180 degrees, which is very suitable for wall panels, cabinets or special-shaped connections without affecting the overall appearance. The connectors cast by high-strength materials can be perfectly attached In the closed groove, the verticality is guaranteed.

The beneficial effects produced by the utility model are: the connecting piece is designed as an integrated dovetail tenon structure, which is used for the connection of two plates, and the plates can be connected at any angle, and can be widely used in home decoration. The two panels can be tightly fastened after splicing. The dovetail structure can prevent disengagement under tension. After installation, the stability is strong. At the same time, the installation is convenient. The installation can be completed by simply pressing the connector, which saves installation time and does not require any tools for assistance. After installation, the overall appearance of the two panels will not be affected. In addition, the overall cost is not high, economical and practical, and it is the most economical connection way, its versatility is suitable for any board.
