可选的，所述延长控制杆设置于所述手持杆的内部，所述手持杆用于支撑所述内窥镜，所述延长控制杆用于控制所述内窥镜进行转向。Optionally, the extended control rod is disposed inside the hand-held rod, the hand-held rod is used to support the endoscope, and the extended control rod is used to control the endoscope to turn.
在上述实施例中，该装置能够通过手持杆对内窥镜进行支撑，避免内窥镜在工作的过程中依附在待测开关设备的内壁上，同时，能够利用延长控制杆对内窥镜进行控制，使内窥镜能够在待测开关设备内部进行任意方向的操作。In the above embodiment, the device can support the endoscope through the hand-held rod, so as to avoid the endoscope from adhering to the inner wall of the switch device to be tested during the working process, and at the same time, the extension control rod can be used to carry out the operation of the endoscope. control, so that the endoscope can be operated in any direction inside the switch device to be tested.
