1. A switch handle component, comprising a manipulating handle, a locking plate, a fixed seat, a touching switch and a first tension spring, wherein:
the fixed seat is fixed to a frame;
the manipulating handle is fixedly connected to the lower part of the locking plate;
the locking plate is rotatably connected to the fixed seat;
one end of the first tension spring is fixed to the frame and is provided near a rotating shaft of the locking plate, and the other end thereof is fixed to the middle of the locking plate;
when the manipulating handle rotates to different positions, the first tension spring applies tension in different directions to the locking plate, respectively, so as to realize the automatic locking of the manipulating handle after switching among the OFF position, the dead point position and the ON position;
wherein the touching switch is provided on the frame and a limiting block mechanism is provided on the locking plate, and the limiting block mechanism is in contact with the touching switch when the manipulating handle rotates to the OFF position.
