Referring to fig. 3, a baffle 35 is further fixedly connected to one side of the mounting block 3 away from the base 1, the baffle 35 is located above the handle 333 and flush with one end of the mounting block 3 facing the circuit breaker body 2, and when it is rainy, the baffle 35 can shield rainwater to prevent the handle 333 from being wetted by rainwater and enter from the placing hole 33, so that the rotating shaft 331 is rusted to affect the service life of the product. Simultaneously, the baffle 35 is far away from one side of the installation block 3 and the two vertical side faces of the baffle 35 and the installation block 3 are fixedly connected with the guide plate 351, the guide plate 351 and one end of the baffle 35 departing from the breaker body 2 are arranged at an obtuse angle, and rainwater on the baffle 35 can drip to the ground along the guide plate 351 and can play a role in guiding the rainwater.

Meanwhile, a blocking box 36 is hinged to one end, facing the handle 333, of the baffle 35, the blocking box 36, one face, facing the handle 333, of the baffle 35 and one face, facing away from the base 1, of the mounting block 3 form a closed box together, the handle 333 and a rotating shaft 331 located outside the mounting block 3 can be sleeved, and therefore the phenomenon that the handle 333 is wetted by rainwater due to influence of external force (such as wind power) and the rainwater enters the placing hole 33, and accordingly damage to the mounting screw 311 is caused is avoided.

Referring to fig. 3, in order to fix the relative position of the retaining box 36 on the mounting block 3, one side of the mounting block 3 away from the base 1 is hinged with a clamping block 37 with a rectangular cross section, the clamping block 37 is located below the retaining box 36, one end of the retaining box 36 away from the baffle 35 is fixedly connected with a clamping plate 361, and meanwhile, a through hole 3611 for the clamping block 37 to pass through is formed in the clamping plate 361. When keeping off box 36 lock on handle 333, joint piece 37 passes from through-hole 3611, then rotatory joint piece 37, joint piece 37 just fixes joint board 361 between joint piece 37 and installation piece 3 to fix the relative position who keeps off box 36 and installation piece 3, thereby avoid keeping off taking place relative rocking between box 36 and the installation piece 3 under the exogenic action and influencing normal rain work of sheltering from.

Referring to fig. 4, a hook 352 is hinged to an end of the baffle 35 facing the handle 333, a hook 362 for hooking the hook 352 is fixed to the catch box 36, and when the hook 352 is hooked to the hook 362, an opening formed by the catch box 36, the baffle 35 and the mounting block 3 faces downward. The worker can directly rotate the handle 333 to complete the assembly and disassembly of the vacuum circuit breaker, the operation of the worker is not interfered, and the operation is more convenient.

To sum up, when the vacuum circuit breaker needs to be mounted on the cradle, the hook 352 is hooked on the hanging ring 362 at a position where the handle 333 leaks out of the hanging ring, and then the worker directly rotates the handle 333, the handle 333 drives the driving bevel gear 332 to rotate through the rotating shaft 331, the driving bevel gear 332 also drives the driven bevel gear 321 engaged with the driving bevel gear to rotate, and the mounting screw 311 screwed with the driven bevel gear 321 is driven by the driven bevel gear 321 to move towards the opening end of the mounting hole 31, so that the mounting operation is completed by connecting the mounting screw with the external cradle. After the installation is accomplished, the staff can directly take off couple 352 from link 362, then under the action of gravity, keep off box 36 and keep away from the one end downstream articulated with baffle 35, pass in joint piece 37 follow through-hole 3611 of joint board 361 until, then the staff directly rotates joint piece 37 and just can block joint board 361 and fix the relative position who keeps off box 36 between installation piece 3 and the joint board, the operation is very simple, need not again with the help of extra mounting tool, just can accomplish whole installation dismantlement work.
