As shown in fig. 1 to 7, an operating handle for connecting a switch cabinet and a grounding switch comprises a handle 1, a main shaft 3, a first movable mechanism 2 and a second movable mechanism 4, wherein the end of the handle 1 is movably connected with the main shaft 3 through the first movable mechanism 2, and the second movable mechanism 4 is arranged on the main shaft 3 and connected with a rotating shaft of the grounding switch 6.

The handle comprises a handle 1, a circular truncated cone 1-1, a handle limiting bulge 1-2, a fan-shaped bulge 1-2 concentric with the circular truncated cone 1-1, and a central angle of the fan-shaped bulge is 60-120 degrees.

Wherein, the main shaft 3 is a hexagonal optical axis.

The first movable mechanism 2 is cylindrical in shape, and a step is arranged on the outer side of the first movable mechanism 2, so that the first movable mechanism 2 can be rotatably arranged on a cabinet door of the switch cabinet 5.

The inner side of the first moving mechanism 2 includes three parts: a handle inserting part 2-1, a first movable mechanism limiting bulge 2-2 and a main shaft inserting part 2-3.

The handle insertion part 2-1 is arranged at one end of the first movable mechanism 2 and is a containing space which can contain the end part of the handle 1, the inner wall of the handle insertion part is a cavity matched with the circular truncated cone 1-1 at the end part of the handle 1, and the end part of the handle 1 can rotate in the containing space.

The spindle insertion part 2-3 is arranged at the other end of the first movable mechanism 2 and is a hollow cavity matched with the spindle 3, the cross section of the inner wall of the spindle insertion part is a regular hexahedron matched with a hexagonal optical axis, and after the spindle 3 is inserted into the spindle insertion part 2-3, the spindle insertion part 2-3 can drive the spindle 3 to synchronously rotate.

The first movable mechanism limiting bulge 2-2 is arranged between the handle insertion part 2-1 and the spindle insertion part 2-3 and is a fan-shaped bulge concentric with the first movable mechanism 2, the central angle degree of the first movable mechanism limiting bulge is 180 degrees, and the first movable mechanism limiting bulge 2-2 and the handle limiting bulge 1-2 at the top end of the circular table 1-1 are positioned on the same plane; that is, the first moving mechanism limiting bulge 2-2 and the handle limiting bulge 1-2 are also concentric, when the two bulges rotate together, a fan ring with the central angle of 240-300 degrees can be formed, namely, no matter the two bulges rotate clockwise or anticlockwise, a gap of 60-120 degrees always exists, and the gap of 60-120 degrees is the idle stroke.
