Line, thus be unable to control the electric contact point 13 and be powered, when the inside spin line of the rotary sleeve 21 and the outer spiral shell of the annular sleeve 14
When lira coordinates, the rotary sleeve 21 is rotated, the rotary sleeve 21 can drive the fork 20 to slide to the left, and the bolt
First 20 when sliding to the left, and described first, which slides bar 15 and second, slides bar 16 and can be inserted respectively into first hole slot 25 and second
In hole slot 26, and it is described be seated bar 22 described first can be pushed to slide bar 15 and second slide bar 16 and slide to the left, inserted when described
When 20 left side of plunger is bonded with the first annular 11 left end wall of slot, described first, which leads to slot 150 and second, leads to slot 160 all
In the narrow groove 156, therefore, the photosensitive sensor 17 can receive the light that the lamp bead 157 is sent out, so as to
The photosensitive sensor 17 can control the electric contact point 13 to be powered, and power Transmission can be seated bar by the electric contact point 13 to described
On 22, it is achieved in the power supply to electrified maintained equipment；
After the completion of power supply, rotary sleeve 21 described in backwards rotation, when inside spin line and the annular sleeve 14 of the rotary sleeve 21
When external spiral line is detached from cooperation, the fork 20 is extracted to the right, and the socket 10 is restored to original state.
The beneficial effects of the invention are as follows：Since the socket in apparatus of the present invention is in original state, described first slides
Bar and second slides bar and is extend into described be seated by top pressure to the right under the action of first tension spring and the second tension spring respectively
In slot, described first, which leads to slot and second, leads to slot not in the narrow groove, and described first, which slides bar and second, slides bar
The narrow groove is obstructed, the contact is not touched under being acted on without external force, and the photosensitive sensor and lamp bead simultaneously close off, institute
Electric contact point no power is stated, therefore, is connect when the people for lacking awareness of safety is inserted into be seated in slot with metal rod with the electric contact point
When touching, the generation of electric shock accidents will not be caused, and metal rod is difficult to lead to slot and second by first to lead to slot and be pressed into simultaneously
Into narrow groove, therefore, security risk is substantially reduced.
In use, by it is described be seated bar be inserted into it is described be seated in slot, when inside spin line and the ring of the rotary sleeve
During the external spiral line cooperation of shape set, the rotary sleeve is rotated, the rotary sleeve can drive the fork to slide to the left, and described
When fork slides to the left, described first, which slides bar and second, slides bar and can be inserted respectively into first hole slot and the second hole slot
In, and it is described be seated bar described first can be pushed to slide bar and second slide bar and slide to the left, when the fork left side with
During the first annular slot left end wall fitting, described first, which leads to slot and second, leads to slot all in the narrow groove, due to
Described be seated when bar is inserted into described be seated in slot can contact, and can press the contact with the electric contact point, described to touch
It turns round after being touched, the photosensitive sensor and lamp bead are opened, and therefore, the photosensitive sensor can receive the lamp bead and be sent out
The light gone out, so as to which the photosensitive sensor can control the electric contact point to be powered, and the electric contact point can be by power Transmission to institute
It states and is seated on bar, be achieved in the power supply to electrified maintained equipment；Moreover, because the inside spin line and external spiral line are matched
It closes, the rod lock that is seated can be seated described in slot, therefore, powered stable can be made, accidentally kick or encounter and is described
Accident power-off will not occur during fork；
