[0025] The use method and advantages of the present invention: A turbine runner blade processing support tool, the working process is as follows: When processing the impeller, first put one corner of the impeller into the side clamp assembly 5 in the right clamping frame 11 to clamp and fix it. After fixing one side of the impeller, start the thrust motor 2 according to the length of the impeller blade to move the left clamping frame 3 and the positioning frame 8 forward together to adjust the distance between the left clamping frame 3 and the positioning frame 8. Then, make the side clamp assembly 5 on the top of the top winding sleeve 4 close to the impeller blade, pull the telescopic push rod 5011 on one side of the ring 504, and drag the long rod 5010 and the pull rod 508 through the telescopic push rod 5011, so that the ladder block 507 pulls the hollow ladder frames 505 on both sides inward to close.
