The movement of the moving block 209 makes the moving clamping column 201 move towards the fixed clamping column 202, thereby clamping the other end of the fan blade. At this time, the fan blade is firmly fixed on the clamping workbench 205. After that, when the clamping guide block 203 contacts the surface of the fan blade, it will be retracted by the compression spring 212 and move inside the fixed cylinder 208. Further, the clamping guide block 203 will be retracted under the action of the compression spring 212 when it contacts the surface of the fan blade due to the influence of the shape of the fan blade. It can adapt to different shapes and sizes of the fan blade for clamping and fixing.
