[0002] With the development of society, people's pursuit of quality of life is constantly improving. When choosing furniture, consumers are no longer limited to a single function, but more hope to maximize the utilization rate of furniture, which is the modern thinking.

[0003] For example, when it comes to chairs or sofas, consumers are more interested in comfort, such as functional iron frames that can provide multiple usage modes, such as normal sitting posture, leisure posture, and full lying posture. As research and development continues to deepen, the functions of functional iron frames are becoming more and more numerous. Therefore, many switch mechanisms will appear in the functional iron frames to limit the expansion or folding of the functional iron frames. Many problems will also arise as a result. For example, in many cases, the position of the switch mechanism cannot be set in a position area that is convenient for operation, resulting in the user being unable to conveniently control the switch mechanism, which will significantly reduce the comfort of using the sofa with the functional iron frame. Therefore, the prior art is in urgent need of a structure that can drive the switch mechanism. Summary of the invention

The locking mechanism 1 includes a base 11, a positioning sleeve 12 and a positioning pin 13. The base 11 is installed in a functional iron frame at a position close to the switch mechanism, the positioning sleeve 12 is fixed on the base 11, and the positioning pin 13 is slidably installed in the positioning sleeve 12. The cable 2 includes a protective tube 21 and an iron wire 22 located in the protective tube 21 and capable of moving axially along the protective tube 21. The two ends of the iron wire 22 are respectively connected to the positioning pin 13 and the handle 32, so that the positioning pin 13 is driven to move in the positioning sleeve through the handle 32; the two ends of the protection tube 21 are respectively fixed on the handle seat 31 and the base 11.

[0020] Specifically, the handle seat 31 is an L-shaped structure and has a first plate 311 and a second plate 312. The first plate 311 is provided with a pivot groove 314. After the lower end of the handle 32 passes through the pivot groove 314 of the first plate 311 from top to bottom, the middle part of the handle 32 corresponds to the pivot groove and is pivotally connected to the inner walls of both sides of the pivot groove 314 through a pivot pin. The upper end of the handle 32 is located above the handle seat 31. The two ends of the tension spring 34 are respectively hooked on the middle and lower position of the handle 32 and the second plate 312. The base 11 is a U-shaped structure, and the positioning sleeve 12 is fixed to the positioning hole 112 on one of the side walls of the base 11 by bolts.

[0021] Both ends of the iron wire 22 have positioning columns 221 that are perpendicular to the extension direction of the iron wire 22. The lower end of the handle 32 has a first connecting groove 321 for one positioning column 221 to be inserted into. The end position of the positioning pin 13 has a second connecting groove 131 for another positioning column 221 to be inserted into, so that the handle 32 is connected to the positioning pin 13 through the iron wire 22.

[0022] The side walls at both ends of the protection tube 21 have an annular groove 211, the second plate 312 of the handle seat 31 has a first groove 312 for an annular groove 211 to be snapped into, and the other side wall of the base 11 has a second groove 111 for the annular groove 211 on the other end of the protection tube 21 to be snapped into, thereby realizing the positioning of the protection tube 21.
