[0002] Automobile clutch plate is a composite material with friction as its main function and structural performance requirements. Automobile friction materials are mainly used to manufacture brake friction plates and clutch plates. The clutch is a mechanism that transmits force through axial compression and loosening of two clutch friction plates with flat surfaces. When the automobile clutch plate is installed in the hole, the automobile clutch plate shakes inside the pressure plate and requires the help of auxiliary tools to install it in the hole. Auxiliary tools are tools used to help users complete specific tasks, operations or improve work processes.

[0003] At present, the existing automobile clutch plate auxiliary tool that is convenient for hole installation is used. Since the hole installation auxiliary tool adopts the principle of expansion bolts, the external threaded sleeve is enlarged by bolts so that the threaded sleeve is in contact with the axial position of the automobile clutch plate and the pressure plate, and the automobile clutch plate in the pressure plate is axially positioned and fixed, so as to meet the hole installation requirements. However, since different automobile clutch plates have different sizes and axial spaces, the automobile clutch plate auxiliary tool that is convenient for hole installation needs to select the appropriate size of hole installation auxiliary tool to complete the installation of the automobile clutch plate. This is not only cumbersome to operate, but also the lower sleeve will lose its resistance filling ability due to elastic deformation after long-term use, thereby leaking gaps from the axis and causing the automobile clutch plate to be loosely fixed.
