Figurative structure for clamping a decorative lamp string

A figurative structure for clamping a decorative lamp string having a plurality of lamp sockets, each socket having a taper-shaped outer surface, with a lower part having two symmetrical flat surfaces, an upper end of said socket engaged with a bulb, said figurative structure comprising:

• a lamp-mounting frame with a plurality of spaced apart fastening bases, each fastening base having spaced arms:
• two open ended, spaced apart, adjacent positioning plates connecting the spaced arms, each adjacent pair of positioning plates opening in opposite directions, respectively;
• two symmetrical hooks extending from the spaced arms in directions opposite to the positioning plates, the two hooks being located between the associated, spaced apart positioning plates;
• a distance between said spaced arms being larger than a minimum outer diameter of said sockets;
• an inner side of each said hooks having a curved surface to fit a curved surface of said socket;
• ends of said two hooks being spaced apart an open distance approximately equal to a thickness between said two symmetrical flat surfaces on said socket;
• an inner surface of one of said two positioning plates having a concave surface to fit a curved surface on said socket, the other of said two positioning plates having two flat surfaces extending from a concave surface towards said spaced arms to form a positioning groove;
• a hollow portion being formed by said positioning plates said hooks, and said spaced arms so as to facilitate said sockets to be inserted into said open ends of said hooks, and said bulb of said socket assembly being positioned in said hollow portion above said fastening base.
