Groove, it is additionally provided with the plug housing and extends up and down and through the narrow groove of first slide slot and the second slide slot, it is described
Narrow groove upper and lower ends, which match, is provided with lamp bead, and described be seated in groove sidewall is installed with electric contact point and contact, described narrow
It is installed with the light sensor being connected with the electric contact point at narrow slot center, the light sensor is controlling the electricity
The power on/off of contact, first is glidingly provided with respectively in first slide slot and the second slide slot slides bar and second and slide
Bar, described first, which slides bar and second, slides to be respectively arranged with first passed through up and down in bar and lead to groove and second and leads to groove, and
Described first, which leads to groove and second, leads to groove and shifts to install, and the first annular groove left end wall is fixedly installed annular sleeve, described
External spiral line is provided with annular sleeve outer shroud；The fork left side matches to be provided with up and down is seated what groove was engaged with described
Be seated bar, it is described be seated to be provided with bar left side bar and second slided with described first respectively slide the first hole that bar is engaged
Groove and the second hole slot, rotary sleeve are rotatably mounted with the fork outer shroud, the fork left end is provided with the second ring
Shape groove, the rotary sleeve inwall left end are provided with the inside spin line towards second annular groove.
Further technical scheme, be installed with respectively in first slide slot and the second slide slot the first extension spring and
Second extension spring, first extension spring and the second extension spring slide bar and second with described first and slide bar and be fixedly connected respectively.
Further technical scheme, described first leads to groove to the described first distance for sliding bar right-hand member and the narrow groove
Difference to the distance for being seated groove is equal to the depth of first hole slot；Described second leads to groove slides the bar right side to described second
The distance at end and the narrow groove are seated depth of the difference equal to second hole slot of the distance of groove described in.
Further technical scheme, is additionally provided with the 3rd annular groove on the fork outer shroud, in the 3rd annular groove
Also it is rotatably mounted with the projection mutually fixed with the rotary sleeve inwall.
Further technical scheme, the light sensor, the contact and lamp bead electrical connection.
The beneficial effects of the invention are as follows：
Because the plug housing in apparatus of the present invention is in original state, described first, which slides bar and second, slides bar respectively described
It is seated described in being extend into the presence of first extension spring and the second extension spring by top pressure to the right in groove, described first leads to groove and second
Lead to groove not in the narrow groove, described first, which slides bar and second, slides bar and obstruct the narrow groove, the contact
It is not touched under being acted on without external force, the light sensor and lamp bead simultaneously close off, the electric contact point no power, therefore, when scarce
The people of weary awareness of safety is inserted into metal rod to be seated in groove when being contacted with the electric contact point, will not cause the hair of electric shock accidents
It is raw, and metal rod is difficult to lead to groove and second by first to lead to groove while be pressed into narrow groove, therefore, is substantially reduced
Potential safety hazard.
In use, by it is described be seated bar be inserted into it is described be seated in groove, when inside spin line and the ring of the rotary sleeve

Line, thus the uncontrollable electric contact point 13 is powered, when the inside spin line and the outer spiral shell of the annular sleeve 14 of the rotary sleeve 21
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 latch
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 promoted to slide bar 15 and second slide bar 16 and slide to the left, inserted when described
When the left side of plunger 20 is bonded with the first annular left end wall of groove 11, described first, which leads to groove 150 and second, leads to groove 160 all
In the narrow groove 156, therefore, the light sensor 17 can receive the light that the lamp bead 157 is sent, so as to
The light 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, the power supply to electrified maintained equipment is achieved in；
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 departs from cooperation, the fork 20 is extracted to the right, and the plug housing 10 is restored to original state.
The beneficial effects of the invention are as follows：Because the plug housing 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 in the presence of first extension spring and the second extension spring respectively
In groove, described first, which leads to groove and second, leads to groove 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 light 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 groove 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 groove and second by first to lead to groove while be pressed into
Into narrow groove, therefore, potential safety hazard is substantially reduced.
In use, by it is described be seated bar be inserted into it is described be seated in groove, when inside spin line and the ring of the rotary sleeve
When the external spiral line of shape set coordinates, 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 promoted to slide bar and second slide bar and slide to the left, when the fork left side with
During the first annular groove left end wall fitting, described first, which leads to groove and second, leads to groove all in the narrow groove, due to
Described be seated when bar is inserted into described be seated in groove can contact with the electric contact point, and can press the contact, described to touch
Turn round after being touched, the light sensor and lamp bead are opened, and therefore, the light sensor can receive the lamp bead and be sent out
The light gone out, so as to which the light sensor can control the electric contact point to be powered, and the electric contact point can be by power Transmission to institute
State and be seated on bar, be achieved in the power supply to electrified maintained equipment；It is additionally, since matching somebody with somebody for the inside spin line and external spiral line
Close, the rod lock that is seated can be seated in groove described, therefore, powered stable can be made, accidentally kick or encounter described
Also accident power-off will not occur during fork；
