With the development of society, there are more and more types of furniture, including beds, cabinets, dining tables, dining chairs, bookshelves, desks and chairs, shoe cabinets, coffee tables, etc. Furniture is usually assembled from different parts through furniture connectors. The most common connecting rod structure of furniture connectors is a nut, an eccentric wheel and a connecting rod, which is usually called a three-in-one structure. The method of use is to pre-install the nut to a furniture component, then lock the connecting rod to the nut, and finally pass the connecting rod through another furniture component and rotate the eccentric wheel to lock the connecting rod, and finally realize the assembly of two furniture components into one. The advantage of the connecting rod structure of this common furniture connector is that the nut, eccentric wheel and connecting screw are standard parts, which are easy to obtain and low in cost. However, the existing connecting rod is generally tightened by a screwdriver. Excessive force will cause damage to the screw head. It is troublesome to disassemble and assemble after assembly. The disassembly and assembly tools are single, time-consuming and labor-intensive, and inconvenient to use. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Summary of the invention
