Abstract
Abstract A revolving safety socket of the present invention has a uniquely-designed stand, which serves as a switching device. It consists mainly of a circular hole in the case cover and a circular recess in the case base. Located between the circular hole and the circular recess is a revolving stand having receptacles therein. When the socket is not in use, the conductive member of the revolving stand is not in contact with the copper clip which is connected to the power supply. Only when a plug is inserted into the revolving stand, which is then rotated for a 90-degree angle, would the conductive member become engaged with the copper clip to permit the power supply to be on. Additionally, the socket has the reversed L-shaped fasteners to hold the protruded block of the plug firmly in place, ensuring that the plug can not be accidentally pulled out of the socket.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A revolving safety socket, either a wall type or a mobile type with an extension cord attached thereto, comprising: a socket having a case body structure with a case cover and a case base; said case cover having a circular hole with two reversed L-shaped fasteners located oppositely thereby; said case base having a circular recess with two set columns formed thereby at opposite location; said set columns having electro-conductive copper clips attached thereto; said circular recess and said circular hole being located coaxially with the revolving stand; and a revolving stand of cylindrical structure having receptacles formed therein, a flange formed around upper end portion thereof, and a blind hole formed in the base thereof to receive a spring; said receptacles having conductive clips formed therein, which extends outwards horizontally in an opposite direction to form conductive members, whereby upon insertion of a plug into the socket, the revolving stand rotates 90° such that the conductive members of the receptacles engage the copper clips of the columns to establish an electrical connection.
Claim 2
Dependent Claim
173 words
A revolving safety socket, either a wall type or a mobile type with an extension cord attached thereto, comprising: a socket having a case body structure with a case cover and a case base; said case cover having a circular hole with two reversed L-shaped fasteners located oppositely thereby; said case base having a circular recess with two set columns formed thereby at opposite location; said set columns having electro-conductive copper clips attached thereto; said circular recess and said circular hole being located coaxially with the revolving stand; and a revolving stand of cylindrical structure having receptacles formed therein, a flange formed around upper end portion thereof, and a blind hole formed in the base thereof to receive a spring; said receptacles having conductive clips formed therein, which extends outwards horizontally in an opposite direction to form conductive members, whereby upon insertion of a plug into the socket, the revolving stand rotates 90° such that the conductive members of the receptacles engage the copper clips of the columns to establish an electrical connection.
