The shell forms a slot and plug holes adapted for receiving a plug. The buckle mechanism is pivotably disposed to the shell and is exposed out of the shell via the slot. The buckle mechanism further forms a buckle portion which is able to alternatively lock on or release the plug when the buckle mechanism pivots so that the locking socket of the present invention is adapted for the plug to insert in. Also, the buckle mechanism alternatively abuts against the plug to prevent the plug from detachment. Thereby, the present invention provides a locking socket with simpler structure, improved structure intensity, and better positioning. ## Claims ### Claim 1 A locking socket, adapted for receiving a plug having a pin and a cover wherein the cover surrounding the pin, the locking socket including: a shell, having a top face, the shell forming a plurality of plug holes recessed from the top face, the plug holes being adapted for receiving the pin of the plug, the shell further forming slot recessed from the top face, the slot being separated from the plug holes so as to prevent from covered by the plug; a buckle mechanism, having a pivot portion, a connecting portion, and a buckle portion, the connecting portion connecting the pivot portion to the buckle portion, the pivot portion being rotatably disposed to the shell and being able to rotate around an axis, the pivot portion being located below the top face, the connecting portion being pivotably inserted in the slot, the buckle portion being located above the top face so that the buckle mechanism is able to pivot between a first position and a second position, the buckle portion moving toward the plug holes when the buckle mechanism pivot toward the first position so that the buckle portion is able to be abutted by the plug; wherein the shell forms a groove recessed from the top face, the groove surrounds the plug holes and communicates with the slot, the groove is adapted for the cover of the plug to insert therein, the pivot portion is separated from the top face by a predetermined distance so that the pivot portion is located below the cover when the cover is inserted in the groove. ### Claim 2 (depends on 1) The locking socket of claim 1, wherein the pivot portion is located below a bottom face of the groove. ### Claim 3 (depends on 1) The locking socket of claim 1, wherein the buckle portion and the pivot portion are located at a side of the connecting portion near the plug holes. ### Claim 4 (depends on 2) The locking socket of claim 2, wherein a standard plane is defined by an extension of an outer surface of the groove, the buckle portion and the pivot portion are located on or inside the standard plane. ### Claim 5 (depends on 3) The locking socket of claim 3, wherein a standard plane is defined by an extension of an outer surface of the groove, the buckle portion and the pivot portion are located on or inside the standard plane. ### Claim 6 (depends on 4) The locking socket of claim 4, wherein a length of the axis of the pivot portion extending into the standard plane is larger than a length of the buckle portion extending into the standard plane when the buckle mechanism is located at the first position. ### Claim 7 (depends on 5) The locking socket of claim 5, wherein a length of the axis of the pivot portion extending into the standard plane is larger than a length of the buckle portion extending into the standard plane when the buckle mechanism is located at the first position. ### Claim 8 (depends on 1) The locking socket of claim 1, wherein the pivot portion is located inside a circumference defined by the top face of the shell. ### Claim 9 (depends on 1) The locking socket of claim 1, further including a repositioning mechanism, the repositioning mechanism abutting against the buckle mechanism so that the buckle mechanism tends to return to the first position. ### Claim 10 (depends on 1) The locking socket of claim 1, wherein the buckle mechanism has a protrusion, the protrusion protrudes from the buckle portion away from the side of the buckle portion having the plug holes. ### Claim 11 (depends on 9) The locking socket of claim 9, wherein the buckle mechanism has a protrusion, the protrusion protrudes from the buckle portion away from the side of the buckle portion having the plug holes.
