When the turning tool body 102 needs to adjust the deflection angle to the left, the staff can turn the hexagonal bolt cover 109 to the left, so that the main gear 107 is reversed, and the sub-gear 106 is engaged accordingly, so that the turning tool body 102 on the connecting block 105 starts to rotate to the left. When the turning tool body 102 needs to adjust the deflection angle to the right, the staff can turn the hexagonal bolt cover 109 to the right. The main gear 107 rotates forward, and the sub-gear 106 engages accordingly, so that the tool body 102 on the connecting block 105 starts to rotate toward the right.
