1. The elastic element is a monolithic hollow section circular shaft with compact structure and simple geometric shape, which is easy to process with high dimensional and form accuracy.

2. The hollow section has a strong resistance to torsion and bending, and the stress at the neutral axis of the shaft pin is the highest.

3. When the hollow section shaft pin is subjected to vertical and horizontal bending, the section with zero bending moment is in the same section.

4. When designing a larger capacity shaft pin sensor, the central hole is also larger, and the double-shear type electro-negative strain gauge can be pasted inside the hole, i.e., well protected and the vacuum-filled inert gas sealing process can be implemented.

5. Easy to assemble with related load-bearing parts and convenient to use.
