Conventional connectors involve the use of many parts, many installation steps, cannot hide the connectors, and the process is complicated. The connectors are easily damaged when exposed. The structure of the connectors is one-piece molded, the cost is high, and it is impossible to save costs by assembling multiple parts. In addition, the components of conventional connectors are usually installed by direct plug-in. The fixation of the components after installation is poor, and they are prone to falling off and shifting, resulting in failure of the connection of the connectors, which is relatively inconvenient.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1) The connecting sleeve rod body is aligned with the embedded part and slides. By aligning the card joint with the socket and squeezing the spring through the movable rod, the card joint slides to the left through the installation slide, passes the limit card and is clamped on the lower side of the installation clamp. This design allows the connecting sleeve rod body and the embedded part to be plugged into each other and hidden inside the plate. It is easy to install and will not be exposed to the outside, and has a long service life.

[0012] 2) The connecting sleeve rod body is installed into the mounting hole through the hexagonal limiting holes at the upper and lower ends and is screwed into the outer thread through the hexagonal key. At the same time, the reinforcing screw can be glued and inserted into the hexagonal limiting hole at the upper end, and the reinforcing screw is synchronously driven to rotate and screw into the mounting hole, thereby further reinforcing the connecting sleeve rod body. After the embedded part is inserted into the mounting hole, it can be clamped on the inner side of the limiting cavity through the outer expansion fixing piece to further fix the embedded part. Finally, the limiting card can limit the card joint to prevent it from sliding out of the installation easily during daily use. To remove the installation, only a large force is required to make the card joint pass over the limiting card to remove the installation, and the installation card can be installed movably through the limiting blocks and embedded parts at both ends. This split design is convenient for installation and replacement of components, does not require integrated production of embedded parts, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

A reinforcing screw 6 is movably inserted into the inner side of the hexagonal limiting hole 3 at the upper end. If it is necessary to further strengthen the installation strength of the connecting sleeve rod body 1, the reinforcing screw 6 can be glued and inserted into the hexagonal limiting hole 3 at the upper end. By rotating the hexagonal key, the reinforcing screw 6 is synchronously driven to rotate and screw into the installation hole, which further reinforces the connecting sleeve rod body 1.

[0023] The lower side of the embedded part 7 is movably connected with an installation card 12, and the upper side of the card joint 5 is fitted with the lower side of the installation card 12.

The upper side of the limited top piece 13 is in contact with the lower end of the spring 2, and the outer side of the connecting sleeve rod body 1 is fixedly provided with a thread 14. When in use, a suitable installation hole is punched on the plate, and then the card joint 5 is pushed into the connecting sleeve rod body 1 using an allen key, so that the allen key is plugged into the hexagonal limiting hole 3 at the lower end, and the allen key is rotated so that the connecting sleeve rod body 1 is screwed into the installation hole through the outer thread 14. The installation slide 9 is tilted, and the lowest end of the installation slide 9 is located below the installation card 12.

[0025] The outside of the embedded part 7 is evenly provided with outward-expanding fixing pieces 15. The embedded part 7 is inserted into the mounting hole in another plate. A limited cavity is provided on the inside of this mounting hole, so that after the embedded part 7 is inserted into the mounting hole, the outward-expanding fixing piece 15 on the outside is clamped on the inner side of the limiting cavity to further fix the embedded part. The lower end of the connecting sleeve body 1 is fitted with the upper side of the embedded part 7, and limiting holes 16 are provided on the front and rear sides of the embedded part 7. The front and rear sides of the mounting clip 12 are fixedly connected to the limiting blocks 17, and the limiting holes 16 are clamped with the limiting blocks 17.

[0026] Working principle: When using this device, a suitable installation hole is punched on the plate, and then the card joint 5 is pushed into the connecting sleeve rod body 1 with an allen key, so that the allen key is plugged into the hexagonal limiting hole 3 at the lower end, and the allen key is rotated so that the connecting sleeve rod body 1 is screwed into the installation hole through the outer thread 14. If it is necessary to further strengthen the installation strength of the connecting sleeve rod body 1, the reinforcing screw 6 can be inserted into the hexagonal limiting hole 3 at the upper end by glue reinforcement, and then the allen key is rotated to synchronously drive the reinforcing screw 6 to rotate and screw into the installation hole, thereby further reinforcing the connecting sleeve rod body 1. Then the embedded part 7 is inserted into the installation hole in another plate, and a limited cavity is provided on the inner side of this installation hole, so that after the embedded part 7 is inserted into the installation hole, the outer outward-expanding fixing piece 15 is clamped on the inner side of the limiting cavity to further fix the embedded part.

Finally, the connecting sleeve rod body 1 is aligned with the embedded part 7 and slides. By aligning the card joint 5 with the socket 8 and squeezing the spring 2 through the movable rod 4, the card joint 5 slides to the left through the installation slide 9, passes over the limiting card 11 and is clamped on the lower side of the mounting clip 12 to complete the installation. At this time, the limiting card 11 can limit the card joint 5 to prevent it from sliding out of the installation easily during daily use. To remove the installation, only a large force is required to make the card joint 5 pass the limiting card 11 to remove the installation.
