Abstract: An improved structure of Christmas lamp holder including a lamp cover and a lamp holder body is so configured that when the lamp cover and the lamp holder body are engaged and fixed, in addition to pressing the electrical wire through the pressing block of the lamp cover, at the same time, the first and second pressing protrusions of the pressing block of the lamp cover press the outer insulation layer of the electrical wire to achieve a more stable pressing fixation effect and increase the load-bearing tensile force to obtain a better tensile effect.
