Claim:
1. A safety socket for an appliance plug having two or more pins, comprising: at least one socket body having two or more receptacles isolated with each other, and comprising a live wire connection circuit, a neutral wire connection circuit and a locking and controlling mechanism, wherein said locking and controlling mechanism is activated to an operation state when said two or more pins of said appliance plug are inserted into said corresponding receptacles of said socket body, and that said live wire connection circuit and said neutral wire connection circuit are electrically disconnected when said locking and controlling mechanism is in an idle state, thereby preventing electric shock, wherein said receptacles of said socket body include a live wire receptacle, a neutral wire receptacle and an earth wire receptacle while said pins of said appliance plug include a live wire pin, a neutral wire pin and an earth wire pin, wherein when said live wire pin, said neutral wire pin and said earth wire pin of said appliance plug are respectively and simultaneously inserted into said corresponding live wire receptacle, said neutral wire receptacle and said earth wire receptacle, said locking and controlling mechanism is activated by said earth wire pin inserted into said earth wire receptacle to electrically connect said live wire connection circuit and said neutral wire connection circuit, wherein said earth wire receptacle has a sidewall, wherein an action hole is provided in said sidewall of said earth wire receptacle, wherein said locking and controlling mechanism comprises a pushing element, an actuating element and a reset element, wherein said pushing element has a first end and a second end, wherein said first end of said pushing element transverses said action hole and extends to said earth wire receptacle to be driven by said earth wire pin, wherein said second end opposite to said first end of said pushing element is connected to said actuating element, wherein said actuating element electrically connects said live wire connection circuit and said neutral wire connection circuit in said operation state, wherein said reset element is connected to one of said pushing element and said actuating element in such a manner that when said earth wire pin is removed from said earth wire receptacle, said locking and controlling mechanism is switched to said initial idle state, wherein said socket body comprises a live wire connection switch controlling electrical connection and disconnection of said live wire connection circuit, and a neutral wire connection switch controlling electrical connection and disconnection of said neutral wire connection circuit, wherein said actuating element of said locking and controlling mechanism simultaneously switches on said live wire connection switch and said neutral wire connection switch under said action of said pushing element so as to electrically connect said live wire connection circuit with said neutral wire connection circuit, wherein said actuating element comprises a connector element and two actuating blocks connected to two sides of said connector element, wherein each of said two actuating blocks has an actuating surface applying pushing force to act on said live wire connection switch and said neutral wire connection switch so as to electrically connect said live wire connection circuit and said neutral wire connection circuit.
