The extrusion block 8 can expand to the left and right sides and squeeze into the interior of the furniture board under the action of the pull rod 2.

[0037] In this embodiment, the explosive buckle 1 includes a first expansion shell 11 and a second expansion shell 12, which are buckled and wrapped around the outside of the pull rod 2 to form a cylindrical structure with one end sealed. The inner walls of the first expansion shell 11 and the second expansion shell 12 are provided with a limit platform 13, and the outer walls are provided with a countersunk tooth 4;

[0038] A conical platform 21 is provided at one end of the pull rod 2, and a rod cap 22 is provided at the other end; one end of the spring 3 is abutted against the bottom wall of the explosive buckle 1 (the first expansion shell 11 and the second expansion shell 12), and the other end is abutted against the conical platform 21 of the pull rod 2; the pull rod 2 can open the explosive buckle 1 through the conical platform 21 when subjected to tension, and can overcome the resistance of the spring 3 and completely retract into the interior of the explosive buckle 1 when subjected to pressure.

[0039] In this embodiment, a latch 111 extending in a circumferential direction is disposed on the docking surface of the first expansion shell 11 , and a latch groove 121 matching with the latch 111 is disposed on the docking surface of the second expansion shell 12 .

[0040] In this embodiment, the inverted teeth 4 include at least one layer of annular protrusion blocks arranged on the outer wall of the cylinder of the pull-out buckle 1, and the annular protrusion blocks are provided with an inclined portion facing the bottom end of the pull-out buckle 1.
