[0016] Through the above technical solution, the limiting block is used for limiting, and the diagonal support block can be used to reinforce the stability between the base and the support block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model can adjust the height of the floor scale by moving the extension block. When the predetermined position is reached, the bolt is inserted into the connecting hole through the limit block and fixed by the nut. At the same time, the limit rod is clamped into the corresponding limit groove, thereby preventing the base and the support block from moving, thereby ensuring that the floor scale will not be offset.
