Patent ID: 8164303

Claim:
A charging socket for holding an electronic device, comprising: a housing having a base and a holding body covering the base, the holding body having an open receiving recess, and a first holding plate extended upwards from a wall of the receiving recess opposite to an opening of the receiving recess; a gear element having a ring-like body mounted in the base, the ring-like body having a plurality of gear teeth at an outer periphery thereof, and a connecting portion connected with the base by a connecting spring for forcing the ring-like body to rotate; a swingable arm pivoted to the base and having a ratchet tooth at a free end thereof engaged with the gear teeth for stopping the ring-like body from being pulled by the connecting spring to rotate; a movable element having a basic plate slidably received in the receiving recess, and a second holding plate extending upwards from an end of the basic plate away from the first holding plate, facing and spaced from the first holding plate for holding the electronic device therebetween, a side of the basic plate connected with a rack which extends along a sliding direction of the movable element and is lower than a bottom of the basic plate, for engaging with the gear teeth of the gear element, wherein the ratchet tooth of the swingable arm is swung to disengage with the gear teeth, the ring-like body is pulled by the connecting spring to rotate, the second holding plate is urged to move away from the first holding plate because of the engagement between the rack and the gear teeth, wherein when the second holding plate is pushed to approach the first holding plate, the gear element is brought by the rack to rotate, the ratchet tooth slides along the gear teeth and stops the gear element from being pulled by the connecting spring to rotate reversely.
