[0032] When in use, the first support plate 4 and the second support plate 5 can be fixed together with the furniture parts respectively through the clamping frame 15 and the fourth bolt 16. At this time, the interface uses this device to connect two adjacent furniture parts, and when installing the clamping frame 15, first remove the first bolt 3, and then pull the first support plate 4 and the second support plate 5 to rotate along the third bolt 14 as the rotation axis. At this time, the angle between the first support plate 4 and the second support plate 5 can be adjusted. Finally, the first support plate 4 and the second support plate 5 are connected to the furniture parts respectively through the fourth bolt 16 and the clamping frame 15, and finally the first bolt 3 is installed to fix the position of the pull rod 2 inside the sleeve 1. By adjusting the angle between the first support plate 4 and the second support plate 5, the device can be adapted to the assembly between furniture with different angles, thereby improving the adaptability of the device.

[0033] Reference Figure 1 and 3 A first connection seat 12 is fixedly connected to the middle of one side of the first support plate 4, and the sleeve 1 is rotatably connected to the first connection seat 12. A second connection seat 13 is fixedly connected to the middle of one side of the second support plate 5, and one end of the pull rod 2 is rotatably connected to the inside of the second connection seat 13.

[0034] The sleeve 1 and the pull rod 2 can be installed respectively through the first connecting seat 12 and the second connecting seat 13.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The first support plate 4 has a first cavity formed inside, the first plug plate 6 is slidably connected inside the first cavity, the second support plate 5 has a second cavity formed inside, the second plug plate 7 is slidably connected inside the second cavity. The first support plate 4 and the second support plate 5 are both threadedly connected with third bolts 14 on the adjacent sides, and the third bolts 14 on both sides are respectively abutted against the outer walls of the first plug plate 6 and the second plug plate 7.

[0036] The first cavity and the second cavity can respectively increase the interaction space for the first plug plate 6 and the second plug plate 7, and the third bolt 14 can be used to fix the position of the first plug plate 6 in the first support plate 4 and the position of the second plug plate 7 in the second support plate 5. Therefore, during the process of assembling furniture, the first plug plate 6 and the second plug plate 7 can be pulled out by removing the third bolt 14. At this time, the length of the first support plate 4 and the first plug plate 6 after combination, and the length of the second plug plate 7 and the second support plate 5 after combination can be extended, so that the distance between adjacent stress points during furniture assembly can be shortened, which is beneficial to improving the structural stability of the furniture after assembly.

[0037] Reference Figure 1 and Figure 4 A first connecting rod 8 is fixedly connected to one side of the first plug plate 6, and a second connecting rod 9 is fixedly connected to the top and bottom of one side of the second plug plate 7, and the first connecting rod 8 is located between the two second connecting rods 9. A second bolt 10 is provided in the middle of the first connecting rod 8, and the second bolt 10 passes through the first connecting rod 8 and the second connecting rod 9, and a nut 11 is threadedly connected to the bottom of the second bolt 10.

[0038] The first connecting rod 8 and the second connecting rod 9 can be used to connect the first plug plate 6 and the second plug plate 7, and after loosening the second bolt 10, the first support plate 4 and the second support plate 5 can be rotated along the second bolt 10 as the rotation axis, so as to adjust the angle between the first support plate 4 and the second support plate 5, and the second bolt 10 and the nut 11 can be used to squeeze the first connecting rod 8 and the second connecting rod 9, so that the angle between the first support plate 4 and the second support plate 5 can be fixed.

[0039] Working principle: When in use, first remove the fourth bolt 16, then the card frame 15 can be removed from the first support plate 4 and the second support plate 5, then move the sleeve 1 to make the first support plate 4 and the second support plate 5 against two adjacent parts of the furniture, then use the fourth bolt 16 to reinstall the card frame 15 on the first support plate 4 and the second support plate 5, then the two adjacent furniture parts can be combined with the device to complete the assembly of the furniture parts, and before installing the card frame 15, remove the first bolt 3 and loosen the second bolt 10, then pull the first support plate 4 and the second support plate 5 to move the first support plate 4 and the second support plate 5. The plate 4 and the second support plate 5 rotate along the third bolt 14 as the rotation axis, so the angle between the first support plate 4 and the second support plate 5 can be adjusted, and finally the clamping frame 15 is installed. During the swinging of the first support plate 4 and the second support plate 5, the sleeve 1 and the pull rod 2 will be pulled to slide against each other. After the first bolt 3 is installed into the sleeve 1 and the pull rod 2, the position of the pull rod 2 inside the sleeve 1 can be locked, so that the angle between the first support plate 4 and the second support plate 5 can be fixed, thereby improving the scope of application of the device.

[0040] When installing the device, the first bolt 3 and the third bolt 14 are removed, and the first plug plate 6 and the second plug plate 7 can be pulled to slide inside the first support plate 4 and the second support plate 5, respectively, so as to extend the length of the first support plate 4 and the first plug plate 6 combined, and the length of the second plug plate 7 and the second support plate 5 combined, and then the third bolt 14 is installed into the first support plate 4 and the second support plate 5, and the third bolt 14 can be used to squeeze the first plug plate 6 and the second plug plate 7, so that the first support plate 4 and the first plug plate 6 can be extended. The total length of the combination of the first plug plate 6 and the first support plate 4 is fixed, and the total length of the second support plate 5 and the second plug plate 7 is fixed. When the total length of the first plug plate 6 and the first support plate 4 is extended, the pull rod 2 is also pulled to slide with the sleeve 1. By installing the third bolt 14, the total length of the combination of the pull rod 2 and the sleeve 1 can be fixed. By extending the total length of the first plug plate 6 and the first support plate 4, as well as the total length of the second plug plate 7 and the second support plate 5, the distance between adjacent stress points during furniture assembly can be reduced, which is beneficial to improving the structural stability of the furniture after assembly.
