Embodiment
As shown in Figure 1 to Figure 2, a kind of telescopic car top protective fence containing safe electric switch, including it is fixed on car top
Lower guardrail, lower guardrail includes the multiple lower beams 11 being mutually permanently connected and lower vertical beam 10, and the lower beam 11 is equipped with fixed
Position part 3, further including can include the multiple upper beams being fixed to each other along the upper guardrail 21 that lower guardrail moves up and down, the upper guardrail 21
21 and upper vertical beam 20, the upper vertical beam 20 is equipped with sliding groove 201, and 201 bottom of sliding groove and/or middle part are equipped with inclination
Upward card slot 202, locating piece 3 and the sliding groove 201 and card slot 202 of the lower guardrail are slidably connected, and further include at least one set
