Pole switches have good outdoor adaptability and can withstand harsh weather conditions. They have high safety and reliability, ensuring the stable operation of the power system, and are usually designed to be small in size, making installation and transportation convenient. In addition, they are also equipped with corresponding operating mechanisms and protection devices to ensure convenient and safe operation. The pole switch protection device is an indispensable device for the operation of the pole switch, and the pole circuit breaker used with the pole switch in the protection device has the ability to detect and quickly disconnect fault currents, including overload and short-circuit currents, and can automatically protect the power grid.

Thus, only the drive mechanism 601 needs to be controlled individually to realize the transmission of multiple sets of bolts 4. Therefore, there is no need to repeatedly install bolts 4 at multiple points to fix the base plate 2, thereby effectively improving the installation and dismantling efficiency of the circuit breaker body 1.

[0027] Furthermore, the drive assembly 5 includes a toothed plate 501 and a driven gear 502.

[0030] As Figures 1 to 5 shown, through the design that the plurality of driven bevel gears 6012 are meshingly connected with the drive bevel gear 6014, when the rotating rod 9 drives the drive bevel gear 6014 to rotate, the plurality of threaded sleeves 6016 can be moved close to or away from each other, so as to realize the rotation of the rotating rod 9, and the synchronous movement of the plurality of connecting components 602 can be controlled.
