Folding isolation device and switch cabinet thereof

The utility model discloses a folding isolation device. The folding isolation device structurally comprises a fixing unit, a telescopic unit and a connecting unit. The telescopic unit is connected to the fixing unit through the connecting unit to form a shear type mechanism, and the shear type mechanism can freely stretch out and draw back under driving of external force. The folding isolation device is arranged on the switch cabinet, so that the mistaken opening and closing of the valve baffle can be effectively reduced, and the safety and the reliability are improved. The potential safety hazards of operators are greatly reduced, and the operation efficiency is also improved. The safety of operators is improved through installation of a traditional isolation device, but the traditional isolation device is not easy to disassemble or fold, and after improvement, an original integrated isolation device is changed into a foldable isolation device. And when not in use, the folding table is not only easy to fold,
