In other embodiments, the limiting structure can also be composed of a protrusion inside the connector housing and a groove on the fixing screw 11 along the axial direction of the fixing screw 11.

[0041] The flip device of this embodiment is used to assemble the isolating switch, such as Figure 5 The schematic diagram of a flip device of the present invention assembled with an isolating switch is shown in FIG. Figure 1 The isolating switch is composed of an isolating switch housing 12, a moving end assembly, a static end assembly, a quick grounding, a transmission assembly and other components. The isolating switch housing 12 is provided with a process hole for positioning and connecting with the connecting head 6. Before installation, the fixing screw 11 in the connecting head 6 is fixed in the connecting head 6 under the joint action of the first return spring 14 and a limiting structure provided in the connecting head housing and between the fixing screw for limiting the moving range of the fixing screw in the axial direction of the connecting head, and the threaded end of the fixing screw 11 will not protrude from the connecting end of the connecting head housing, thereby preventing the fixing screw 11 from scratching the isolating switch housing 12.
