[0029] During implementation, the wiring port 114 drives the fixing block 431 to slide inside the fixing plate 42. Under the combined action of the fixing block 431 and the fixing plate 42, the fixing plate 42 is guided, so that the fixing block 431 drives the anti-loosening block 433 to be clamped into the anti-loosening slot 432.

[0030] Further, as Figure 2 and Figure 4As shown in the figure, a convenient storage mechanism 2 is provided on the inner wall of the placement groove 105 and the surface of the test pen 104. The interior of the convenient storage mechanism 2 includes a retaining belt 21, a clamping post 22, and a convenient storage part 23. The convenient storage part 23 is arranged on the inner wall of the placement groove 105 and the surface of the test pen 104. The convenient storage part 23 is composed of an elastic clamping member 231, a male magic tape 232, and a female magic tape 233. A retaining belt 21 is arranged on the inner wall of the placement groove 105. The retaining belt 21 is rotatably engaged with the inner wall of the placement groove 105. A clamping post 22 is installed on the inner wall of the placement groove 105. One end of the clamping post 22 penetrates through the retaining belt 21 and extends to the outside of the retaining belt 21. Elastic clamping members 231 are installed on the surface of the clamping post 22. The elastic clamping members 231 are engaged with the inner wall of the retaining belt 21. Female magic tapes 233 for preventing the loosening of the retaining belt 21 are installed on the inner wall of the retaining belt 21. Male magic tapes 232 are installed on the inner wall of the placement groove 105. The surfaces of the male magic tapes 232 and the female magic tapes 233 cooperate with each other.

[0031] During implementation, the user places the test pen 104 inside the placement groove 105. The user rotates the retaining belt 21 inside the placement groove 105, causing the retaining belt 21 to rotate inside the placement groove 105. When the retaining belt 21 rotates, the retaining belt 21 drives the clamping post 22 to move above the retaining belt 21. At this time, the clamping post 22 drives the elastic clamping member 231 to snap into the inside of the retaining belt 21. Under the action of the elastic clamping member 231, the loosening of the clamping post 22 is prevented. At this time, the male magic tape 232 moves to contact the surface of the female magic tape 233. Under the combined action of the male magic tape 232 and the female magic tape 233, the loosening of the retaining belt 21 is prevented, enabling the test pen 104 to be stably placed inside the placement groove 105 to achieve the function of conveniently storing the test pen 104 in the power-on detection device.

[0032] Working principle: When in use, first place the device box body 1 on the surface of the power distribution cabinet body 102, causing the device box body 1 to drive the positioning block 33 to snap onto the corresponding surface of the power distribution cabinet body 102. At this time, under the elastic force of the extension spring 34 in the groove, the arc-shaped clamping member 35 is driven to move, causing the arc-shaped clamping member 35 to snap onto the surface of the positioning block 33. Under the combined action of the extension spring 34 and the arc-shaped clamping member 35, the loosening of the positioning block 33 is prevented. Subsequently, the user tightens the mounting screw 32 on the surface of the mounting block 31. Under the action of the mounting screw 32, the mounting block 31 and the device box body 1 are installed at the designated position on the power distribution cabinet body 102, making the device box body 1 more stable during installation and facilitating operation to achieve the function of general assembly of the power-on detection device. Thus, when the power-on detection device is in use, the device box body 1 can be assembled on the surface of any power distribution cabinet body 102, making it more convenient for the user to operate when the power-on detection device is in use.

[0033] Subsequently, the user inserts the connection line 115 into the inside of the connection port 114 to connect and energize the test electric pen 104 inside the placement groove 105. At this time, the connection port 114 drives the fixed block 431 to slide inside the fixed plate 42. Under the combined action of the fixed block 431 and the fixed plate 42, the fixed plate 42 is guided, so that the fixed block 431 drives the anti-disengagement block 433 to snap into the anti-disengagement slot 432. Under the combined action of the anti-disengagement block 433 and the anti-disengagement slot 432, the fixed block 431 is prevented from disengaging. At this time, the fixed block 431 drives the anti-disengagement member 41 to snap into the fixed plate 42, so that the connection line 115 can be stably inserted on the surface of the connection port 114, avoiding the phenomenon of the connection line 115 becoming loose on the surface of the connection port 114, so as to realize the function of firmly preventing loosening between the connection port 114 and the connection line 115 of the power-on detection device. Thus, when the power-on detection device is in use, the connection line 115 can be stably inserted on the surface of the connection port 114, avoiding the phenomenon that the power-on test of the power distribution cabinet body 102 is inaccurate due to the loosening of the connection line 115 during the use of the power-on detection device, making the power-on detection device safer to use.

[0034] Subsequently, after the test box 108 inside the device box body 1 is energized, the user opens the power distribution cabinet body 102, then pulls the door body 106 on the surface of the storage box 103 and removes the door body 106 from the surface of the storage box 103. The user takes out the test electric pen 104 inside the placement groove 105 and contacts the test point of the electrical component inside the power distribution cabinet body 102 with the test electric pen 104. The line current of the electrical component can be tested under the action of the test electric pen 104. Subsequently, the user adjusts the voltage of the circuit entering the power distribution cabinet body 102 through the power regulator 109. When the user operates the display 101 and the current passes through the sampling resistor 110 and the voltage sensor 111, the sampling resistor 110 and the voltage sensor 111 display the collected data on the display 101. By comparing the data detected on the power distribution cabinet body 102 with the data on the display 101, it can be analyzed whether the power distribution cabinet body 102 is operating normally, and the power-on detection operation of the power distribution cabinet body 102 is completed, facilitating the user to perform the power-on detection operation before using the power distribution cabinet body 102 by himself. At this time, the alarm 112 sounds an alarm to prompt the staff. When the test electric pen 104 detects current in the electrical component, the lamp bead board 107 emits light, indicating that the electrical component is working normally. When the test electric pen 104 detects no current in the electrical component, the lamp bead board 107 does not emit light, indicating that the electrical component is not working normally.

[0035] Subsequently, when the test electric pen 104 is no longer in use, the user places the test electric pen 104 inside the placement slot 105. The user rotates the blocking belt 21 inside the placement slot 105, causing the blocking belt 21 to rotate within the placement slot 105. When the blocking belt 21 rotates, it drives the clamping post 22 to move above the blocking belt 21. At this time, the clamping post 22 drives the elastic clamping member 231 to snap into the inside of the blocking belt 21. Under the action of the elastic clamping member 231, the loosening of the clamping post 22 is prevented. At this time, the male magic tape 232 moves to contact the surface of the female magic tape 233. Under the combined action of the male magic tape 232 and the female magic tape 233, the loosening of the blocking belt 21 is prevented, enabling the test electric pen 104 to be stably placed inside the placement slot 105, so as to realize the function that the power-on detection device can conveniently store the test electric pen 104. As a result, when the power-on detection device is in use, the test electric pen 104 that has been used can be stored inside the storage box 103, making it convenient to bundle up the test electric pen 104 during the use of the power-on detection device, and finally completing the use of the power-on detection device.
