A camera fixing tube 3 is fixedly connected to one side of the sliding sleeve 2 through an extension arm. A plurality of raised blocks 4 extending toward the center of the fixing tube 3 are arranged on the top of the inner wall of the fixing tube 3. The other end of each raised block 4 is respectively fixed with a spring piece 15 extending to the bottom of the fixing tube 3. A gap is left between the side wall of the spring piece 15 and the side wall of the fixing tube 3. A triangular limiting protrusion 5 with a tip pointing to the center of the fixing tube 3 is respectively arranged at the lower end of each spring piece 15. The fixing tube 3 is used to insert a camera module of a visual robot, such as a camera module with a fixing column at the bottom. In this way, the fixing column is inserted into the fixing tube 3 and fixed by the limiting protrusion 5. It is not only convenient to install and disassemble, but also ensures firmness of use after installation.
