The main power switch 6 is powered on and started, and the timer 8 automatically enters the countdown for 30 minutes. When the timing is completed, it means that the wiring test is over. When the next batch of trainees take the test, the reset button 9 can be directly pressed to restart the timing. The device comes with a timing module, so students can truly recreate the electrician examination scene during the wiring process, thereby improving the pass rate of students.

[0024] Preferably, a foldable support plate 10 is provided at the lower part of the main box 3. With such a design, students can unfold the foldable support plate 10 horizontally to form a platform on which they can answer theoretical examination questions, without the need to organize a separate theoretical examination venue, which greatly improves the examination efficiency. It should be noted that the folding method of the foldable support plate 10 is consistent with the folding method of the square table into a round table in the prior art.

[0025] Preferably, an AC-DC conversion module is provided in the main box 3, and the AC-DC conversion module is provided with a power interface extending out of the main box 3. In specific implementation, the mains power is connected to the power interface, and converted into direct current below 36V by the AC-DC conversion module, such as direct current 24V to power the components of the device, to ensure the safe operation of the trainees during the wiring process and prevent electric shock and personal injury.

[0026] Preferably, a wiring intelligent detection circuit that cooperates with the first training panel 4, the second training panel 5 and the timer 8 is provided in the main box 3. The first training panel 4 generally includes a motor unidirectional continuous operation training panel. Trainees perform unidirectional continuous operation wiring (with inching control) on the motor as required according to the given electrical schematic diagram. Before powering on, use an instrument to check the circuit to ensure that there are no safety hazards before powering on. The motor can normally perform the corresponding operations of inching, continuous operation and stop. The internal wiring has been completed. Trainees only need to perform wiring operations according to the motor unidirectional continuous operation schematic diagram. The motor is replaced by an indicator light. The first training panel 4 generally includes a motor forward and reverse operation training panel.

Adjustment nuts are sleeved on the threaded rod, which are respectively located on the upper and lower sides of the bottom bracket 1. When the entire device is moved to the required position, the threaded rod can be rotated to allow the support foot 12 to completely take over the support work, so that the universal wheel 11 is suspended in the air, ensuring the stability of the entire device and facilitating the test training. When the test training is completed, the threaded rod is rotated again to allow the support foot 12 to be suspended in the air, so that the universal wheel 11 contacts the ground and moves.
