Rapid detection device for electrical control circuit

The invention discloses a rapid detection device for an electrical control circuit, and relates to the technical field of electrical control circuit detection. The electrical control circuit rapid detection device comprises an oscilloscope body used for circuit detection, the front side of the oscilloscope body is provided with a display screen used for detection display, and the front side of the oscilloscope body is connected with a shading plate used for shading protection in the use process of the display screen through a rotary supporting assembly. According to the rapid detection device for the electrical control circuit, in the process of rapidly detecting the electrical control circuit by using the oscilloscope, when the oscilloscope is used in a direct sunlight or bright environment, the light shielding plate is pushed, so that the light shielding plate is inclined to the front side of the display screen at a certain angle; the front side of the display screen is subjected to shading protection throu
