  • Compared with the prior art, the socket having the structure discussed above has the advantages as below:
    • If the plug needs to be pulled out of the socket, the upper end of the lever is pressed down so that the lever rotates about a hinging point on the middle section thereof to drive the lower end of the lever to ascend, thus the support plate is driven to move upwardly along the guide post, and the pin of the plug will be ejected upwards out of the jack of the socket when the protruding post on the support plate moves upwardly, besides, the pin can be ejected upwards out of the jack easily and conveniently because labor-saving effect is realized by means of the lever and the protruding post is aligned to the pin in the jack, the entire course is labor-saving, convenient and fast; and no contact with the pin is generated in the process of unplugging, thus eliminating the accident of electric shock and obtaining great safety.
  • As an improvement, the socket further comprises a spring for resetting the support plate, in this way, the spring can reset the support plate automatically after a user loosens his hand, at the same time, the upper end of the lever is also driven to reset, which facilitates the next unplugging course.
  • As a further improvement, the lower end of the casing is provided with a guide hole for accommodating the support plate, the upper end of the guide hole is provided with an installation hole, the upper end of the guide post is fixed on the bottom wall of the installation hole, the spring is sleeved on the guide post, the upper end of the spring abuts against the bottom wall of the installation hole, and the lower end of the spring abuts against the support plate, in this way, the spring presses the support plate down automatically after a user loosens his hand on the lever, so as to drive the upper end of the lever to ascend and reset automatically, furthermore, the spring installed in the installation hole is fixed more firm and stably.
  • As a further improvement, the lower end of the lever is provided with a first shaft, the lower end face of the support plate is provided with a shaft base and the first shaft is sleeved in a shaft hole of the shaft base; such a structure is simple and convenient for assembly.
  • As a further improvement, the middle section of the lever is provided with a second shaft, the casing is fixed with a bracket, the upper end of the bracket is fixed with a circular slot and the second shaft of the lever is accommodated in the circular slot of the bracket; such a structure is convenient for assembly, and after assembly, the middle section of the lever can be hinged to the casing conveniently, so the structure is stable and reliable.
