In order to fix the goods placed above the weighing device 4, a fixing mechanism 6 is installed above the first base plate 2 and the second base plate 3. The working principle of the fixing mechanism 6 is as follows: when the driving motor 7 is started, it drives the bidirectional threaded rod 8 to rotate. Since the bidirectional threaded rod 8 is fixedly arranged on the first base plate 2 through a clamping seat, the bidirectional threaded rod 8 is fixedly arranged on the first base plate 2 and the second base plate 3. The upper and lower plates 2 and 3 are connected by a plurality of two-way threaded rods 8, and the lower and upper plates 2 and 3 are connected by a plurality of two-way threaded rods 8. The upper and lower plates 2 and 3 are connected by a plurality of two-way threaded rods 8. The upper and lower plates 2 and 3 are connected by a plurality of two-way threaded rods 8.

The upper and lower plates 2 and 3 are connected by a plurality of two-way threaded rods 8. The upper and lower plates 2 and 3 are connected by a plurality of two-way threaded rods 8. The upper and lower plates 2 and 3 are connected by a plurality of two-way threaded rods 8. 68 rotates, the upper bending push-pull rod 65 and the lower bending push-pull rod 68 push the card plate 610 to move forward and backward synchronously through the push and pull of the bending rod, so as to adjust the distance between the card plates 610 in the two sets of fixing mechanisms 6, so as to fix the measured objects above the weighing device 4. In order to enhance the portability of the device, the first bottom plate 2 and the second bottom plate 3 are connected to each other through the docking plug plate 9 and the docking tooth plate 10, and a fixed long rod 11 is used to penetrate the docking plug plate 9 and the docking tooth plate 10 to connect the first bottom plate 2 and the second bottom plate 3 together. At the same time, the first bottom plate 2 and the second bottom plate 3 are plugged into the docking groove 13 above the base plate 1 through the plug plate 12. This design makes the first bottom plate 2 and the second bottom plate 3 The fixing mechanism 6 above the second base plate 3 can be quickly disassembled and installed. In addition, the device is also equipped with a storage support mechanism 18. When the device needs to be moved or stored, the storage support mechanism 18 can be folded and retracted. When the device needs to be used for cargo measurement, the hydraulic telescopic rod 186 will rotate the angle to push the support rod 184, and at the same time drive the movable bracket 183 to rotate, so that the movable bracket 183 and the support rod 184 form a ninety-degree right angle, and the support rod 184 is perpendicular to the ground.
