[0002] Flying probe testing is the latest solution to some major problems in circuit testing. It replaces the bed of nails with probes and uses multiple motor-driven, fast-moving electrical probes to contact the pins of the device and perform circuit measurements. Compared with traditional circuit testing, flying probe testing has the advantages of high efficiency, simplicity, safety and protection against electric shock.

[0003] Based on the above, the inventors found that the existing circuit flying probe test device clamps and fixes the circuit board through a clamping member. When the detection work is completed, the old circuit board needs to be removed before the new circuit board can be reinstalled. The replacement gap is long, which affects the circuit detection efficiency. Therefore, in view of this, the inventors studied and improved the existing structure and provided a circuit function detection device with an anti-electric shock function instrument, in order to achieve a more practical purpose.
