The rotation of the meshing gear 160 rotates the screw rod 140, so that the moving block 130 moves upward with the measuring ruler 110 until the top of the measuring ruler 110 abuts against another sheet metal, and the hand wheel 170 stops rotating, and then the limit bolt 182 is rotated to make the bottom end of the limit bolt 182 abut against the limit groove 124 to prevent the hand wheel 170 from rotating.
