[0002] Overvoltage and undervoltage protectors are commonly used electrical devices in the electrical field. They are often used in conjunction with circuit breakers in circuits and are used in home and shopping mall power distribution lines as protection against overvoltage, undervoltage, phase loss and neutral line loss. However, the alarm indicator lights of existing overvoltage and undervoltage protectors are usually always on, so that corresponding alarm prompts cannot be given according to the voltage conditions, resulting in unclear voltage conditions and difficulty in maintenance operations. At the same time, the heat dissipation performance of existing overvoltage and undervoltage protectors is poor, resulting in high temperature inside the protectors after long-term use, which brings certain effects. Therefore, a voltage prompt structure for overvoltage and undervoltage protectors is needed to solve the above problems. Utility Model Content

[0022] A clamping block 14 is fixedly connected to the bottom of the housing 7, and a through hole 15 is formed in the clamping block 14. The through hole 15 provides a clamping point for the clamping rod 17, so that when the clamping rod 17 is clamped into the through hole 15, the connection between the two housings 7 can be ensured to be fixed, and the two housings 7 can be prevented from being separated accidentally.

[0023] A card slot 16 is provided on the upper side of the housing 7, and a card rod 17 is slidably connected in one of the housings 7. The card slot 16 provides an embedding point for the card block 14, so that when the card block 14 is inserted into the card slot 16, the positions of the through hole 15 and the card rod 17 can correspond to each other, so that the card rod 17 can be smoothly inserted into the through hole 15;

[0024] The card rod 17 is inserted into the card slot 16, and the two rotating shafts 9 are fixedly connected with gears 11. When the two housings 7 are combined, the two gears 11 can be in a meshing state, so that when one of the rotating shafts 9 drives one of the gears 11 to rotate, the other gear 11 meshed therewith can drive the other rotating shaft 9 to rotate synchronously, so as to achieve the purpose that the two cooling fans 10 can rotate at the same time;
