The size of the through hole is adapted to the size of moving threaded column 34, so that moving threaded column 34 can pass through limit pad 35. The size of positioning hole 37 is adapted to the size of moving threaded column 34. The corresponding surface of limit plate 38 is attached to the outer side of fixing pad 31. After one end of moving threaded column 34 is movably inserted into the corresponding positioning hole 37, the angle of rotation shaft 6 can be locked.

[0036] The locking mechanism 4 includes a guide connecting sleeve 41, a support connecting frame 42 fixed to one end of the guide connecting sleeve 41, a mounting bracket 43 fixed to the top of the support connecting frame 42, a rotating plate 44 rotatably connected to the bottom of the mounting bracket 43 via a rotating shaft, a positioning block 45 fixed to one side of the rotating plate 44, a transmission frame 46 rotatably connected to one side of the rotating plate 44 via a rotating shaft, a movable bracket 47 rotatably connected to one end of the transmission frame 46 via a rotating shaft, an anti-detachment sliding block 48 fixed to the top of the movable bracket 47, a connecting handle 49 installed on the top of the anti-detachment sliding block 48, the guide connecting sleeve 41 and the circuit breaker body 1 are fixedly connected, the guide connecting sleeve 41 has a limiting groove inside to accommodate the movement of the connecting handle 49 and the anti-detachment sliding block 48, the waterproof protective cover 5 has a positioning groove inside, the size of which is adapted to the size of the positioning block 45.
