Are the link 62, the lever 61, the link 63, and the lever 64
And an operating mechanism 60 composed of One end of the lever 64 that rotates about the handle operation shaft 65a is a link 6
3 and one end of the link 63 is connected to the lever 61. One end of the lever 61 uses the fixed shaft 61a as a rotation shaft,
The other end of the lever 61 is connected to a link 62. Link 62
Is connected to a receiving bracket 51 to which the power transformer 13 is attached. In order to reach the disconnection state, the operation handle 66 is inserted into the handle insertion opening 65, and when the operation handle 66 is operated upward, the lever 64 is moved to the lever 61 through the link 63.
When the lever 61 rotates about the fixed shaft 61 a, the receiving bracket 51 is pushed up via the link 62. Since the receiving metal member 51 is regulated by the guide 52 in the vertical movement, the power transformer 1 is connected via the receiving metal member 51.
3 is lifted, and the connection portion 13 is disconnected. In the disconnected state, since the lever 61 and the link 62 stop at the stopper 90 beyond the dead center, the power transformer does not fall naturally. To reach the connection state, when the operation handle 66 is inserted into the handle insertion opening 65 and the operation handle is operated downward, the lever 64 pushes out the lever 61 via the link 63, and the lever 61 rotates about the fixed shaft 61a. By doing so, the receiving bracket 51 can be
Lower. Since the receiving metal fitting 51 is restricted by the guide 52 in the downward movement, the power supply transformer 13 is lowered via the receiving metal fitting 51, and the connecting portion 13 is connected.

め、充電部に近づくことがなく、安全に作業が行える。According to the present invention, as described above, the disconnection between the automatic switch and the power transformer can be easily performed by operating the operation handle upward. In addition, when the automatic switch can be operated manually, the operation is the same as the manual opening and closing operation, so that the operation handle can be shared. Further, since the separation can be performed via the mechanism, the work can be performed safely without approaching the charging section.
