[0006] Furthermore, two gears meshing with each other are provided inside the upper scale body between the two guide holes, and teeth are provided on the two guide posts and respectively mesh with a nearby gear; each guide post meshes with the corresponding gear to form a gear rack pair, and the two gears mesh with each other, which can improve the synchronization of the movement of the two guide posts.

[0007] Furthermore, the sides of the two guide columns are provided with vertically extending limit grooves, the inner walls of the two guide holes are fixed with blocks and each block extends into the limit groove of the corresponding guide column; the length of the limit groove is reasonably set to avoid hindering the stretching of the hanging scale, and at the same time, the blocking effect of the block on the guide column is utilized to prevent the lower scale body from separating from the upper scale body, thereby avoiding the lower scale body falling accident caused by excessive physical weight measurement.

[0008] The beneficial effect of the utility model is that the hanging combined metering scale of the utility model can combine multiple hanging scales for use, thereby achieving the effect of expanding the measuring range and meeting the needs of more customers and industries.
