After the pulling rope 5 is deformed and lengthened due to fatigue after being stretched for many times, the product can be adjusted to a suitable maximum tensioning amount by quickly replacing / adjusting the ring 12.

[0066] In addition, the fixed shell 8 is sleeved with a collection pipe 10, and a sealing ring 11 is arranged between the collection pipe 10 and the fixed shell 8.

[0067] The adjusting device of the embodiment of the utility model solves the problem that the hardness of the endoscope insertion tube cannot be adjusted, and is beneficial to surgical operation.
