Claim Text:
1. A single-line string lamp, comprising a plurality of lamp bodies connected in series and a plurality of lead wire segments used for connecting two adjacent lamp bodies or connecting the lamp bodies with power connectors; a conductive element being fixed at an end, which is connected with a corresponding lamp body, of each lead wire segment; and each lamp body comprising: a lamp bulb, a lower end of which extends out of at least two lamp pins; a lamp holder, comprising a containing part used for containing a lower portion of the lamp bulb, line holes for the at least two lamp pins to extend out of a bottom of the lamp holder being formed in an edge of the bottom of a containing part; and a hollow connecting base, used for containing the lamp holder, an opening for the conductive element to enter being formed in a bottom of the hollow connecting base, an edge, in which the opening is formed, being provided with a clamping platform for preventing the conductive element from being disengaged after the conductive element enters the opening, and the conductive element being in electrical contact with a corresponding lamp pin; wherein each lead wire segment is provided with a lead wire reinforcing object used for enhancing anti-tensile strength, or a connecting lead wire with enhanced anti-tensile strength is adopted in each lead wire segment; wherein a fixed part is fixed at a position on each lead wire segment close to a corresponding conductive element, and when each lead wire segment is subjected to an outward tensile force relative to each corresponding connecting base, relative positional stability between the corresponding conductive element and an inner wall of the corresponding connecting base is maintained by each fixed part; and wherein each lamp body is connected with two lead wire segments, the fixed part comprises a plastic part, and the plastic part is tightly fixed at a position on the two lead wire segments close to the conductive element, so as to fix the two lead wire segments together; and the plastic part is one of: a complete plastic sleeve, a plastic sleeve with a gap, and two plastic sheets with central portions being connected together.
