[0010] Preferably, the head rollover mechanism includes a head mounting plate, a head guide rail assembly, a head conversion plate, plug bolts with bearings and enlarged plug bolts. The head mounting plate is installed on the top of the circular column. The head mounting plate is a "J"-shaped plate structure. Weighing sensors are fixed on both end plates of the head mounting plate. The head guide rail assembly is buckled above the head mounting plate, and the head guide rail assembly and the head mounting plate clamp the weighing sensor. The surface of the head guide rail assembly is screwed with screws, and the screws penetrate the head guide rail assembly and are screwed to the surface of the weighing sensor. The head conversion plate is laterally buckled on the head guide rail assembly, and the head conversion plate is connected to the head guide rail assembly through plug bolts with bearings.
