1. Field of the Invention
The present invention relates to a detachment-preventing plug; in particular, the invention relates to a detachment-preventing plug without a corresponding socket.
2. Description of the Related Art
Conventional detachment-preventing devices are often disposed on sockets rather than on the plugs. For example, FIG. 1 shows a conventional locking frame disposed outside the socket, and the frame defines a compartment for receiving a plug. The drawback of such conventional design is that the compartment defined by the frame must correspond with the size of the plug, or the frame can't strengthen the fixing capability. Furthermore, the frame occupies a certain space, and the usages of the electric equipments are restricted within the place having the special socket. In other words, the electric equipments do not have the detachment-preventing function, which are carried by a user to the place without the special socket.
Based on research, the inventor proposes the present invention to address the above issues.
