In this embodiment, the specific configuration of the U-shaped groove portion 1202 is optimized. Specifically, the weighing module 30 is disposed in the groove of the U-shaped groove 1202, and the weighing module 30 is fastened to the U-shaped groove 1202 by a fastener such as a screw or a bolt. In order to further improve the positional flexibility of the weighing module 30, through long waist holes 1203 are provided on both groove walls of the U-shaped groove 1202, and fasteners such as screws/bolts pass through the long waist holes 1203 to realize adjustable connection of the weighing module 30 and the U-shaped groove 1202. The length of the long waist hole 1203 enables the relative position of the weighing module 30 and the U-shaped groove 1202 to be adjusted according to actual needs.
