The movable socket assembly may include a housing, a plug part installed in said housing, a plurality of elastic conducting contact points formed on said plug part, and an adjusting mechanism for positioning the plug part out of the housing so that the plug part can be removably inserted into an external power outlet. The housing may further include a first housing and a second housing, and the second housing can retract into the first housing to extend the flat insertion piece out of the housing through an opening of the second housing. ## Claims ### Claim 1 An extendable socket assembly, comprising: a housing; a plug part comprising a flat insertion piece installed in said housing; a plurality of elastic conducting contact points formed on said plug part; and an adjusting mechanism comprising a slide guide and a spring mechanism configured for ejecting the flat insertion piece out of the housing along the slide guide for insertion of the flat insertion piece into an external power outlet. ### Claim 2 (depends on 1) The extendable socket assembly of claim 1, wherein said flat insertion piece having two insulation layers and a plurality of conducting strips placed between the two insulation layers, and each conducting strip penetrates one of the two insulation layers to form one of the plurality of elastic conducting contact points at a surface of said insulation layer. ### Claim 3 (depends on 1) The extendable socket assembly of claim 1 further comprising a plurality of holes formed on a side of the housing for receiving an external plug. ### Claim 4 (depends on 2) The extendable socket assembly of claim 2, wherein said plurality of elastic conducting contact points are formed on a same side of the flat insertion piece. ### Claim 5 (depends on 2) The extendable socket assembly of claim 2, wherein said plurality of elastic conducting contact points are formed on different sides of the flat insertion piece. ### Claim 6 (depends on 2) The extendable socket assembly of claim 2, each elastic conducting contact point has one of a curved surface, a plane surface, a waved surface, or a stepped surface. ### Claim 7 (depends on 1) The extendable socket assembly of claim 1, wherein said spring mechanism comprises two springs for ejecting the flat insertion piece out of the housing along the slide guide. ### Claim 8 (depends on 1) The extendable socket assembly of claim 1 further comprising a locking mechanism for locking the flat insertion piece into a position. ### Claim 9 (depends on 8) The extendable socket assembly of claim 8, wherein said locking mechanism comprises a button, a second spring, and a lock key, wherein the second spring can push the lock key to engage a groove formed on the flat insertion piece to lock the flat insertion piece into the position, and wherein the button can push the lock key to disengage the groove to unlock the flat insertion piece from the position. ### Claim 10 (depends on 1) The extendable socket assembly of claim 1, wherein said flat insertion piece further comprises a bulge which stops the flat insertion piece from being completely ejected from the housing. ### Claim 11 (depends on 3) The extendable socket assembly of claim 3 further comprising a safety unit, said safety unit comprising a gate installed between the plurality of holes and a plurality of conductors, a spring attached to the gate, and a slope formed on the gate, wherein when the external plug is inserted into the holes the external plug engages with the slope to push the gate aside so that the external plug can connect to the plurality of conductors. ### Claim 12 (depends on 1) The extendable socket assembly of claim 1, wherein the housing comprises a first housing and a second housing, and the second housing can retract into the first housing to extend the flat insertion piece out of the housing through an opening of the second housing. ### Claim 13 (depends on 12) The extendable socket assembly of claim 12, wherein the adjusting mechanism comprises a spring for ejecting the second housing out of the first housing when the flat insertion piece is being removed from the external power outlet. ### Claim 14 (depends on 12) The extendable socket assembly of claim 12, wherein the second housing comprises an upper housing portion which has a safety unit mount part, a lower housing portion which has a socket core structure, and a bottom portion. ### Claim 15 (depends on 12) The extendable socket assembly of claim 12, wherein the second housing comprises a bulge for preventing the second housing from completely disengage the first housing, and wherein said bulge is formed at an end of the upper housing portion. ### Claim 16 (depends on 1) The extendable socket assembly of claim 1, wherein the housing comprises a chamber for installing a smart chip. ### Claim 17 An extendable socket assembly, comprising: a housing comprising a plurality of holes formed on a side of the housing for receiving an external plug; a plug part installed in said housing; a plurality of elastic conducting contact points formed on said plug part; an adjusting mechanism for positioning the plug part out of the housing so that the plug part can be removably inserted into an external power outlet; and a safety unit comprising a gate installed between the plurality of holes and a plurality of conductors, a spring attached to the gate, and a slope formed on the gate, wherein when the external plug is inserted into the holes the external plug engages with the slope to push the gate aside so that the external plug can connect to the plurality of conductors. ### Claim 18 (depends on 17) The extendable socket assembly of claim 17, wherein said plug part comprises a flat insertion piece and said adjusting mechanism comprises a slide guide and a spring for ejecting the flat insertion piece out of the housing along the slide guide. ### Claim 19 (depends on 17) The extendable socket assembly of claim 17, wherein the housing comprises a first housing and a second housing, and the second housing can retract into the first housing to extend the flat insertion piece out of the housing through an opening of the second housing. ### Claim 20 An extendable socket assembly, comprising: a housing comprising a first housing and a second housing; a plug part comprising a flat insertion piece installed in said housing; a plurality of elastic conducting contact points formed on said plug part; and an adjusting mechanism for positioning the plug part out of the housing so that the plug part can be removably inserted into an external power outlet; wherein the second housing can retract into the first housing to extend the flat insertion piece out of the housing through an opening of the second housing; and wherein the adjusting mechanism comprises a spring for ejecting the second housing out of the first housing when the flat insertion piece is being removed from the external power outlet; the second housing comprises an upper housing portion which has a safety unit mount part, a lower housing portion which has a socket core structure, and a bottom portion; and the second housing comprises a bulge formed at an end of the upper housing portion for preventing the second housing from completely disengage the first housing.
