[0021] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings. In order to solve the problem of operating the switch at a safe distance from the high-voltage equipment cabinet, as Figure 2 As shown, this embodiment shows a high-voltage equipment isolation operation device proposed by the present invention, which is used for Figure 1 The knob switch arranged on the surface of the high-voltage equipment switch cabinet made of magnetic material is used for opening and closing operations, and includes a grip 1, a cylinder 2, an annular magnet 3, an annular airbag 4, a bearing structure 5, a micro air pump 6, and a grip 7.

[0022] The grip rod 1 is a hollow rod-shaped structure wrapped by insulating material, and the grip rod 1 also includes a handle 7 perpendicular to the grip rod 1 .

[0023] The cylinder 2 is a cylindrical structure with one end closed and the other end open. The inner diameter of the cylinder 2 is larger than the outer diameter of the knob switch. The central axis of the cylinder 2 is a straight line. One end of the handle 1 is fixedly connected to the center position of the outer surface of the closed end of the cylinder 2, and the handle 1 is perpendicular to the outer surface of the closed end of the cylinder 2.

[0024] The annular airbag 4 is fixedly connected to the inner wall of the cylinder 2, and the air nozzle of the annular airbag 4 is connected to the micro air pump 6 through an air tube. When the annular airbag 4 is deflated, the inner diameter is larger than the outer diameter of the knob switch. When the annular airbag 4 is inflated, the inner diameter is smaller than the outer diameter of the knob switch. A friction structure similar to dot-like protrusions is provided on the inner side of the surface of the annular airbag 4.

[0025] The inner diameter of the inner ring 501 of the bearing structure 5 is the same as the inner diameter of the open end of the cylinder 2. The inner ring 501 is fixedly connected to the open end of the cylinder 2. The central axis of the cylinder 2 passes through the center of the bearing structure 5.
