The tail servo motor can achieve more precise adjustment. Since the two ends of the tightening machine can move synchronously, the tail servo motor can more accurately control the position and movement of the tightening machine, improving the adjustment accuracy and stability. The disc protrusion can rotate inside the sliding groove, but it does not affect the driving effect of the tightening machine on the tightening head, which means that the tightening head can maintain normal rotation and operation, while also maintaining a stable working state, effectively avoiding failures or stagnation during the tightening process.
