At least a part of the lifting support 182 in the second direction Y is located below the corresponding part of the object placement channel 128, so as to be ready to support the weighed object at any time. Since the upper end face a183 of the lifting support 182 is higher than the lower end face b130 of the bearing slot 129, the weighed object entering the object placement channel 128 is first supported by the lifting support 182. When the weighing object is to be weighed, the weighing platform 80 is slidably connected to the upper end of the bracket body 181, and the bottom bracket 180 moves downward to insert the weighing object into the bearing slot 129. When the lower end surface b130 of the bearing slot 129 is higher than the upper end surface a183 of the lifting support 182, the bearing assembly 121 pulls up the weighing object through the hanging bracket 100 for weighing. After the weighing of the weighing object is completed, the bottom bracket 180 moves upward, and the upper end surface a183 of the lifting support 182 is higher than the lower end surface b130 of the bearing slot 129.
