Specifically, an operation portion adapted for a user to switch moves substantially parallely to a front plate of the safety socket so that the operation portion is adapted for being switched between locking state and unlocking state. ## Claims ### Claim 1 A safety socket, including: a shell, having a front plate, the front plate forming a set of plug holes, the set of plug holes including at least two insertion holes, the insertion holes being adapted for a corresponding plug to insert therein, the plug including at least two metal pins which are able to be inserted into the insertion holes; a suppress mechanism, disposed inside the front plate of the shell, the suppress mechanism corresponding to one of the insertion holes, the suppress mechanism being able to be switched between a release position and a suppress position, the suppress mechanism buckling to the metal pins inserted into the insertion holes when the suppress mechanism is located at the suppress position, the metal pins being able to enter or leave the insertion holes when the suppress mechanism is located at the release position; a limitation mechanism, disposed to the shell, the limitation mechanism including an operation portion and a limiting portion, the operation portion and the limiting portion being in a linking-up correlation, the limiting portion extending near the suppress mechanism, the operation portion being located partially outside the front plate, the operation portion being able to be switched between a first position and a second position, the limiting portion being separated from the suppress mechanism when the operation portion is located at the second position so that the suppress mechanism is able to be switched between the suppress position and the release position freely; wherein a path of the operation portion moving on the front plate is substantially parallel to the front plate. ### Claim 2 (depends on 1) The safety socket of claim 1, wherein the suppress mechanism is resilient so as to tend to located at the suppress position, when the operation portion is located at the first position, the limiting portion buckles to the suppress mechanism so that the suppress mechanism is unable to be switched to the release position. ### Claim 3 (depends on 1) The safety socket of claim 1, wherein the suppress mechanism has a suppress plate and a buckle plate, an end of the suppress plate is fixedly disposed to the shell, an opposite end of the suppress plate is connected to the buckle plate, the buckle plate is movable to change an angle between the suppress plate and the front plate so that the suppress mechanism is able to be switched between the suppress position and the release position. ### Claim 4 (depends on 3) The safety socket of claim 3, wherein the limiting portion includes a first connecting rod, an axle rod, and a second connecting rod, the first connecting rod and the second connecting rod are disposed to the axle rod and are in a linking-up correlation with the axle rod, the axle rod is rotatably disposed to the shell, the operation portion abuts against the first connecting rod, when the operation portion moves, the first connecting rod is driven to pivot around the axle rod to further drive the axle rod to rotate, thereafter the second connecting rod is driven to pivot so that the buckle plate is unable to move freely. ### Claim 5 (depends on 1) The safety socket of claim 1, wherein the operation portion is able to move between the first position and the second position along a straight line. ### Claim 6 (depends on 2) The safety socket of claim 2, wherein the operation portion is able to move between the first position and the second position along a straight line. ### Claim 7 (depends on 3) The safety socket of claim 3, wherein the operation portion is able to move between the first position and the second position along a straight line. ### Claim 8 (depends on 4) The safety socket of claim 4, wherein the operation portion is able to move between the first position and the second position along a straight line. ### Claim 9 (depends on 1) The safety socket of claim 1, wherein the operation portion is pivotable around a rotation axle, the rotation axle is disposed inside the front plate of the shell and is parallel to the front plate. ### Claim 10 (depends on 2) The safety socket of claim 2, wherein the operation portion is pivotable around a rotation axle, the rotation axle is disposed inside the front plate of the shell and is parallel to the front plate. ### Claim 11 (depends on 3) The safety socket of claim 3, wherein the operation portion is pivotable around a rotation axle, the rotation axle is disposed inside the front plate of the shell and is parallel to the front plate. ### Claim 12 (depends on 4) The safety socket of claim 4, wherein the operation portion is pivotable around a rotation axle, the rotation axle is disposed inside the front plate of the shell and is parallel to the front plate.
