[0012] First, by sliding the insert plate downwards, the probe extending from the lower surface of the insert plate is inserted into the part slot. When there is no part in the part slot, the probe is directly inserted into the part slot. When a part has been installed in the part slot, the probe is blocked by the part, causing the probe to slide upwards. The fixture plate can be inspected by whether the probe slides upwards, without the need for the staff to observe with the naked eye. This not only saves time and effort, but also avoids missed inspections and facilitates subsequent assembly.

[0013] Secondly, when the probe slides upward, the first electrode contacts the second electrode, connecting the circuit and illuminating the indicator light, indicating that a part has been installed in the part slot. The indicator light provides a more intuitive reminder to staff whether any part has been missed. Attached Figure Description
