Position bar, the outer wall side of the killer switch are provided with stopper slot corresponding with gag lever post, and the outer wall side of the gag lever post is set
There is chute, and L-type locking bar is slidably connected in chute, the top of the killer switch and the outer wall one for being located at case for circuit breaker
Side is provided with neck, and the upper and lower side of neck inwall is symmetrically connected with several latch segments by spring, and the upper end of the neck connects
It is connected with L-type locked groove corresponding with L-type locking bar.
Preferably, the height of the gag lever post is less than the width of gag lever post.
Preferably, the chute is located at the small side of spacing rod area.
Preferably, the outer wall surface of the latch segment is smooth cambered surface.
Preferably, the outer wall of the spring is socketed with gum cover.
Compared with prior art, the beneficial effects of the utility model are：People disconnect during electricity consumption when needs are artificial
During circuit, 90 degree of L-type locking bar rotate counterclockwise is held by so that chute faces user, L-type locking bar is slided, by L-type locking bar
The outer wall side of switch handle of circuit beaker is connected in, pulls the handle of killer switch to be left behind together along band gag lever post, if only
There is killer switch to fall, and gag lever post is still connected in the inside of neck, then illustrate killer switch be auto-cutout rather than
The reason for artificial.The utility model is simple in construction, easy to operate, and it is artificial origin's disconnecting circuit or inhuman to be easy to distinguish breaker
For reason disconnecting circuit, and suitably it is widely popularized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the stereogram of gag lever post of the present utility model.
In figure：Case for circuit breaker 1, killer switch 2, neck 3, gag lever post 4, fixture block 5, support bar 6, connecting rod 7, rotating shaft
8th, stopper slot 9, L-type locking bar 10, latch segment 11, spring 12, L-type locked groove 13, gum cover 14, chute 15.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of miniature circuit breaker for being easy to distinguish, including case for circuit breaker 1, the outer wall of case for circuit breaker 1
Side is provided with killer switch 2, and the outer wall of case for circuit breaker 1 and being provided with positioned at the both sides of killer switch 2 by loose slot turns
Axle 8, and rotating shaft 8 is fixedly connected with connecting rod 7 through the elongated end of loose slot, the end side of the remote rotating shaft 8 of connecting rod 7 is consolidated
Surely support bar 6 is connected with, and the one end of support bar 6 away from connecting rod 7 is provided with fixture block 5 by cavity, is fixed between two fixture blocks 5
Gag lever post 4 is connected with, the outer wall side of killer switch 2 is provided with stopper slot 9 corresponding with gag lever post 4, the outer wall one of gag lever post 4
Side is provided with chute 15, and L-type locking bar 10 is slidably connected in chute 15, the top of killer switch 2 and is located at case for circuit breaker 1
