According to the position where the screw needs to be installed on the workpiece, loosen the nut 20 and move the two loading blocks 25 along the length direction of the first sliding groove 24. After the movement is completed, screw in the nut 20, and drive the push rod 32 to move through the push block 33. The push rod 32 drives the friction block 31 to move, and the friction block 31 is disengaged from the second sliding groove 17. Move the position of the placement block 14 along the second sliding groove 17 to adjust the position of the workpiece. After the whole is completed, the pushing block 33 is released, and the second elastic member 29 pushes the pushing rod 32 to move, and the pushing rod 32 drives the friction block 31 to move, and the friction block 31 abuts against the second sliding groove 17.
