[0004] However, the probe shape of the measuring instrument in the prior art is very sharp, which may damage the coated film layer, and the buzzer and the indicator light are used separately, so the display and alarm effects are not obvious, and the specific type of the film layer cannot be distinguished. Therefore, it is urgent to design a detection tool for glass conductive film layer to overcome the defects of the prior art and meet the actual application requirements. UTILITY MODEL CONTENTS
[0005] In view of the defects in the prior art, the utility model aims to provide a detection tool for glass conductive film layer, which realizes efficient and reliable detection and alarm functions through specific design of the detection tool, enhances the fault tolerance of the detection tool by working of the parallel buzzer and indicator light at the same time, ensures accurate and timely detection and alarm under various conditions, and quickly measures the voltage value by pressing the normally open switch, so as to determine the film layer type.
[0006] To achieve this purpose, the utility model adopts the following technical solutions:
[0007] This utility model provides a testing tool for a glass conductive film layer. The testing tool includes a housing, one end of which is provided with a probe and the other end is a handle. On any side of the housing away from the probe, there is a buzzer opening, an indicator light opening, a display component, and a normally open switch opening.
[0008] The housing is equipped with a detection circuit, which includes a power module, a normally open switch, a voltmeter, a buzzer, an indicator light, and a voltage divider resistor. The normally open switch is located at the opening of the normally open switch, and the buzzer and the indicator light are located at the openings of the buzzer and the indicator light, respectively.
[0009] The probe includes a first probe and a second probe. The first probe is connected in series with the power module, the voltage divider resistor, the buzzer and the second probe. The indicator light is connected in parallel across the two ends of the buzzer.
[0010] One end of the normally open switch is connected in parallel between the second probe and the buzzer, and the other end is connected in series with the voltmeter. The end of the voltmeter furthest from the normally open switch is connected in parallel between the first probe and the power module.

By having a buzzer and indicator light connected in parallel to work simultaneously, the fault tolerance of the detection tool is enhanced, ensuring accurate and timely detection and alarm under various conditions. Furthermore, by pressing the normally open switch, the voltage value can be quickly measured, thereby determining the film type.
[0012] It should be noted that in this invention, the buzzer and indicator light are connected in parallel. Once the circuit is turned on, the buzzer and indicator light will be activated simultaneously, emitting sound and light respectively. This parallel operation not only improves the response speed of the circuit but also enhances the reliability of the detection tool. Even if either the buzzer or the indicator light is damaged, the system can still continue to perform the detection task through the other component (whether it is sound or light), effectively avoiding misjudgment caused by the failure of a single detection method. The redundancy in the design prevents operator negligence or error.
