[0030] As shown in Figure 1 and Figure 3 , the double-groove rubber plate 7 is fixedly installed on the inner side wall of the protective shell 2, which can resist the two probes on the multimeter 4.
[0031] Further explanation, the double-groove rubber plate 7 plays a role in fixing the position of the probe, preventing the probe from shaking or shifting during detection and affecting the accuracy of the detection results, while also providing some protection to the probe, reducing the possibility of damage due to accidental collisions.
[0032] As shown in Figure 1 , the detection base 1 is provided with a sound outlet 8, and a dust screen 9 is fixedly installed on the inner side wall of the sound outlet 8.
[0033] Further explanation, the sound outlet 8 on the detection base 1 can be used to emit detection-related prompt sounds (such as short-circuit alarm sounds), so that the operator can know the detection results in time without directly observing the display screen of the multimeter 4, and the setting of the dust screen 9 can prevent dust and other impurities from entering the inside of the detection base 1 through the sound outlet 8, avoiding pollution or damage to the internal electronic components, and ensuring the normal operation and service life of the detection tool.

[0042] The utility model can be described by the following operation mode:
[0043] Assembling device: lift the protective shell 2 and make the fixed bolt 3 fixedly installed on the protective shell 2 align with the bolt hole on the detection base 1, slowly put down the protective shell 2, make the same side fixed bolt 3 embedded in the bolt hole, so as to complete the fastening connection of the detection base 1 and the protective shell 2, and build the overall frame structure of the detection tool.
[0044] Then check the placement of the multimeter 4 in the detection base 1, because the outer side wall of the multimeter 4 and the outer side wall of the reinforcing plate 10 on the inner side wall of the bottom of the detection base 1 and the outer side wall of the rubber block 11 on the inner side wall of the detection base 1 are slidably connected, the multimeter 4 should be in a relatively stable position and its two pen should be able to naturally correspond to the top plug of the two-in-two-out connector 5 fixedly installed on the inner side wall of the bottom of the detection base 1, if the pen position is deviated, after slight adjustment, the two pens on the multimeter 4 are accurately embedded in the top plug of the two-in-two-out connector 5, to realize the electrical signal connection of the two, at the same time, the tail plug of the two-in-two-out connector 5 is fixedly installed with the detection female socket 6, thus completing the connection preparation of the detection line.
[0045] Then, arrange the multimeter pen wire, place the same side multimeter pen wire along the inner side wall of the buckle wire plate 13 on the inner side wall of the detection base 1, so that the multimeter pen wire is orderly arranged in the detection base 1, avoiding mutual entanglement and interference with subsequent operation.
[0046] Detecting EPS controller: when the connector pin short circuit detection of EPS controller is carried out, the connector to be detected is connected with the detection female seat 6, the display value of the multimeter 4 is observed or the sound emitted from the sound outlet 8 on the detection base 1 is listened (the existence of the dustproof net 9 can ensure that the inside is not disturbed by dust and the sound is emitted stably), if there is a short circuit condition, a specific prompt sound will be emitted, and the operator judges the detection result according to the sound.
[0047] During the detection process, the double-groove rubber plate 7 on the inner side wall of the protective shell 2 always abuts against the two probes of the multimeter 4, so that the detection accuracy is not affected by the shaking or displacement of the probes caused by external factors, and the sponge pad 12 on the inner side wall of the protective shell 2 also provides buffer protection for the internal components at any time, reduces the damage to the components such as the multimeter 4 caused by accidental collision or falling, guarantees the integrity and functionality of the detection tool, and ensures that the entire detection work is carried out smoothly and accurately.
