Abstract: Provided are fixing clamp and turn-off device. The fixing clamp includes clamp body and an elastic plate, wherein the clamp body includes first section, second section, and third section, the first section and the third section are separately connected to two ends of the second section, and the first section and the third section both are located at the same side of the second section; the elastic plate includes connecting end and an open end, the connecting end is connected to the first section, and gap is provided between the open end and the third section, so that the elastic plate is in cantilevered structure relative to the first section; and an accommodation space is formed between the clamp body and the elastic plate, and at least one of the first section, the second section, and the third section is provided with protrusion part.

Abstract: A high voltage control box with light sensing and timing functions is formed by matching an upper cover and a bottom plate; the upper cover is provided with a rocker switch, a light guide column and a knob; a button switch and a knob switch are arranged in the high voltage control box; the button switch is matched with the rocker switch; the knob switch is matched with the knob; a circuit board is arranged in the high voltage control box; and the button switch and the knob switch are arranged on the circuit board. The high voltage control box with light sensing and timing functions in the present invention controls the switch of the bulbs and the switch time through light sensing and timing of the plurality of lamp strings, enhances intelligence of the lamp strings without manual control, and enhances the market competitiveness of products while saving power.
