Abstract

The utility model belongs to the technical field of rubber tube protection and provides a rubber tube assembly and an operation instrument, the rubber tube assembly comprises a rubber tube body, a protective sleeve body and an end fixing sleeve head, the protective sleeve body is sleeved on the outer side of the rubber tube body, one end of the end fixing sleeve head is sleeved on the outer side of the protective sleeve body, and the other end of the end fixing sleeve head is sleeved on the outer side of the rubber tube body. And the other end axially extends out of the end part of the protective sleeve body and is sleeved on the outer side of the rubber pipe body. By arranging the end fixing sleeve head, the end of the protective sleeve body can be limited and fixed, the fixing mode is convenient to install and good in dirt resistance, and meanwhile the probability of deformation and loosening in the long-time use process is very low.
