When installing a new pulley 14, the support plate 15 is directly aligned with the fixed block 16 for installation. During installation, due to the shape of the clamping block 17, it will be directly squeezed into the interior of the fixed block 16. When it is installed in the correct position, the spring 18 will release the tension and reset the clamping block 17, so that the support plate 15 is fixed to the inflatable shaft body 3, and the installation is completed.
