1. A foldable keyboard comprising: a main body comprising a key portion comprising a plurality of keys, wherein a receiving chamber is defined in a side of the main body;a cover comprising a plurality of receiving grooves aligned with the plurality of keys, wherein when the cove is rotatably engaged on the main body, the plurality of keys is received in the corresponding receiving grooves;a first hinge portion mounted on a middle position of the main body; anda locking element comprising: a locking portion mounted on the main body, wherein the locking portion comprises a sliding block, a fixing portion, and a first elastic element for elastically connecting the sliding block to the fixing portion, the fixing portion defines a slot in a sidewall thereof, the sliding block comprises a bottom, a stopper protruding from a portion of the bottom, and a first pin mounted on the stopper, the fixing portion further comprises a groove, two sliding tracks protruding from a bottom of the groove, a second pin, and a third pin, the slot is defined in a sidewall of the groove between the two sliding tracks, a first receiving space is defined between the two sliding tracks, a sidewall of the sliding track is recessed to form a second receiving space communicating with the first receiving space, two ends of the bottom of the sliding block are placed in the second receiving spaces, the stopper is placed in the first receiving space, thereby slidably connecting the sliding block to the fixing portion;a limiting portion mounted on the main body, wherein the limiting portion comprises a recessed portion defined in a surface of the main body for receiving the locking portion, the recessed portion defines a limiting slot communicating with the slot in a sidewall thereof, the sliding block is attractable by an external magnetic force to move towards the slot until a portion of the sliding block passes through the slot, and is engaged in the limiting slot, the first elastic element is deformed, thereby engaging the locking portion in the limiting portion; anda controlling portion mounted on the main body, and received in the receiving chamber;wherein the main body is operable to be folded along the first hinge portion, the locking portion is operable to engage in the limiting portion to lock the foldable keyboard in a folding state, and the controlling portion is configured to unlock the foldable keyboard from a folding state. 2. The foldable keyboard as described in claim 1, wherein when the external magnetic force disappears, the first elastic element rebounds to drive the sliding block to return to an original position, thereby unlocking the foldable keyboard from the folding state. 3. The foldable keyboard as described in claim 1, wherein the first elastic element is a spring. 4. The foldable keyboard as described in claim 1, wherein the sliding block is a magnet. 5. The foldable keyboard as described in claim 1, wherein the first elastic element comprises a first fixing end, a second fixing end, and a third fixing end, the first fixing end is fixed to the first pin, the second fixing end is fixed to the second pin, and the third fixing end is fixed to the third pin, thereby elastically connecting the sliding block to the fixing portion. 6. The foldable keyboard as described in claim 5, wherein the controlling element comprises a button, a magnet and a second elastic element, the receiving chamber comprises a sliding groove therein, when the foldable keyboard is folded along the first hinge portion, the sliding block is attracted by the magnet to move towards the slot until the portion of the bottom passes through the slot, and the stopper butts against the sidewall of the fixing portion, thereby engaging the locking portion in the limiting portion. 7. The foldable keyboard as described in claim 6, wherein when the magnet is slid over a position of the sliding groove, which corresponds to the limiting slot by the button and the second elastic element, the magnetic force from the magnet applied on the bottom of the sliding block disappears, the first elastic element rebounds to drive the sliding block to return to the original position, the bottom is moved out of the limiting slot, thereby unlocking the foldable keyboard from the folding state. 8. The foldable keyboard as described in claim 6, wherein the second elastic element is a spring. 9. The foldable keyboard as described in claim 1, further comprising a hinge portion rotatably connecting the cover to the main body, and a fixing element, wherein the foldable keyboard is folded along the hinge portion, and is locked by the fixing element in the folding state. 10. The foldable keyboard as described in claim 9, wherein the fixing element comprises a magnet mounted on the cover, and a metal sheet mounted on the main body, the magnet attracts the metal sheet to secure the cover on the main body, thereby locking the foldable keyboard in the folding state. 11. The foldable keyboard as described in claim 9, further comprising a second hinge portion, the cover is folded along the second hinge portion. 12. The foldable keyboard as described in claim 9, wherein the cover is made of flexible material.
