How does the force measuring rod of the compression spring testing machine work?

How does the compression spring testing machine force gauge work ST1Textile Testing Instruments, Testing Equipment Manufacturer

The dowel stretches the spring as the dowel's displacement goes through the string Pull the string wheel to drive a pair of gears to rotate, which drives the pointer to rotate to show the force value. The passive gear also has a coaxial string wheel, and a balance weight is suspended from it, which is used to eliminate the meshing gap, avoid the error of the reading, and make the active needle automatically return to zero after the mold is broken.

It should be noted that since the elongation of the Feder (stretching of the string) is inseparable from the angle of rotation of the gear wheel (display of force value), i.e. :ST1Textile Testing Instruments, Testing Equipment Manufacturer

1) The diameter of the spoke wheel cannot be changed arbitrarily ;ST1Textile Testing Instruments, Testing Equipment Manufacturer

2) String specifications cannot be changed arbitrarily;ST1Textile Testing Instruments, Testing Equipment Manufacturer

3) The string can not be wound on the string wheel for more than one cycle, so as not to indirectly increase the diameter of the wire wheel. ST1Textile Testing Instruments, Testing Equipment Manufacturer
