The visual device connecting part 11 is used for being connected with a matching piece of the visual device, so that the effect of assembling the sleeve of the visual device and the visual device together is realized. The visual system connection 12 is used to connect with the ventilation interface of the ventilation channel of the visual system to achieve the effect of assembling the visual device sleeve and the visual system together. The connection between the connecting piece 1 and the matching piece or the ventilation interface can be sliding fit connection or threaded connection, so as to achieve the function of detachable connection.

In order to ensure the stability and reliability of the connection between the connector 1 and the visual device and the visual system, the mating parts of the visual device connection part 11 and the visual device and the visual system connection part 12 and the visual system may be locked together by a connection locking member such as a fixing pin or a clip.

Then the visual device sleeved with the visual device sleeve is inserted into the ventilation channel of the visual system, and then the visual device is connected with the ventilation interface of the ventilation channel of the visual system through the visual system connecting part 12, so that the purpose of assembling the visual device with the visual system through the visual device sleeve is achieved.

The connecting piece 1 of the sleeve of the visual device can be connected with the matching piece of the visual device, so that the insertion sleeve 2 is sleeved outside the insertion mechanism of the visual device, thereby effectively isolating the insertion mechanism from the external environment, and only the sleeve of the visual device is required to be replaced without cleaning and sterilizing the insertion mechanism when the device is used, thereby improving the use convenience of the visual device.

In one embodiment of the inventive visual device sleeve, the connector 1 has a tubular structure and a partition 14 is provided within the connector 1. The partition plate 14 may be located at the end of the connection member 1 or within the connection member 1. The insertion hole 13 is located on the partition plate 14.

When the outer sleeve and the inner sleeve of the telescopic part 17 have more length overlapping parts, the connector 1 has a shorter length; when the outer sleeve and the inner sleeve of the telescopic part 17 have less overlapping parts of length, the assembly formed by the connection 1 has a longer length.

Still further, the viewing device sleeve further includes a locking member (not shown) for locking the length of the telescoping portion 17. By locking the length of the telescopic part 17, the length of the visual device sleeve can be kept unchanged after being adjusted to a proper length, so that the convenience of the operation of the visual device sleeve is improved. The locking means may be, for example, a locking pin, which locks the relative positions of the outer sleeve and the inner sleeve of the telescopic part 17; the locking means may also be, for example, a catch provided on the outer or inner sleeve of the telescopic part 17.
