The upper plate 10, the bending plate 30, the shipping plate 50 and the lower plate 20 are arranged in sequence from top to bottom. The fixed end of the sensor 70 is connected to the top end of the lower plate 20 through the cushion block 60, and its free end extends into the bending plate 30 and is connected to the bottom end of the upper plate 10 through the force transmission mechanism 40. The right end of the connecting plate 90 is integrally connected with the left side of the bottom end of the bending plate 30. A first through hole 91 is provided at the left end of the connecting plate 90, a second through hole 51 is provided at the left end of the shipping plate 50, and a slot 52 is provided at the right end. The bolt 80 passes through the first through hole 91 and the second through hole 51 in sequence and is threadedly connected to the lower plate 20. The left end of the cushion block 60 is clamped in the slot 52. The right end of the shipping plate 50 is connected to the cushion block 60 through the slot 52, and the left end is connected to the lower plate 20 through the bolt 80. Compared with the installation method of multiple bolts, the installation and removal of the shipping plate 50 is more convenient, and there is only one bolt 80, which reduces the risk of loss. At the same time, the right end of the shipping plate 50 is connected to the cushion block 60 through the slot 52 to prevent the shipping plate 50 from sliding forward and backward, and the connection is achieved through the cushion block 60 provided by the weighing module, without the need for additional clamping parts, simplifying the structural design. Specifically, mounting holes are respectively provided at the four corners of the upper plate 10; fixing holes are respectively provided at the four corners of the lower plate 20; the top of the bending plate 30 is rigidly connected to the bottom end of the upper plate 10, the cross-section of the bending plate 30 is U-shaped, and notches 31 are symmetrically provided on the left and right sides of the bending plate 30, and one of the notches 31 is for the sensor 70 to pass through, and the sensor 70 is loosely matched with the notch 31; the left end of the shipping plate 50 protrudes from the lower plate 20, and when removing the shipping plate 50, unscrew the bolt 80 and pull it out through the left end of the shipping plate 50, which further improves the convenience of removing the shipping plate 50; the bolt 80 is loosely matched with the first through hole 91 and the second through hole 51, respectively.

[0029] like Figure 3 As shown, in order to facilitate the left end of the cushion block 60 to enter the slot 52 for locking, inclined surfaces 100 are formed on both sides of the slot 52, and the two inclined surfaces 100 form a trumpet shape.
