The number of the first pushing rods 800 is the same as the number of the conductive bars 700 of the first conductive mechanism 400, and the first pushing rods 800 are disposed above the pressing plates 720 of the conductive bars 700 of the first conductive mechanism 400 in a one-to-one correspondence. The driving end of the first push-down rod 800 can push down the lower pressing plate 720 of the conductive rod 700 to drive the conductive rod 700 to be electrically connected with the binding post of the circuit breaker 101.

The first guiding sleeves 617 are in one-to-one correspondence with the conductive bars 700 of the first conductive mechanism 400 (i.e., the first guiding sleeves 617 are sleeved outside the conductive bars 700). The first guide sleeve 617 is located below the lifting ring 613 with a gap between the first guide sleeve 617 and the lifting ring 613 such that vertical sliding of the lifting ring 613 is not affected by the first guide sleeve 617. Thereby, the first guide plays a role in guiding the conductive rod 700, so that the conductive rod 700 is more stable when vertically lifted.
