[0086] In an exemplary embodiment, the limiting strip 110 and the slide rail 115 are both disposed on the same side of the gauge body 101 .

[0087] In an exemplary embodiment, a plurality of positioning holes are provided on the limiting strip 110 .

[0088] In an exemplary embodiment, a first positioning hole is defined in the fixing plate 109 .

[0089] In an exemplary embodiment, when the first positioning hole coincides with the positioning hole, the fixing plate 109 is fixed by the positioning pin 111 .

[0090] In an exemplary embodiment, the positioning holes on the limiting strip 110 include a flexible connection deformation stress detection position positioning hole, a flexible connection deformation stress zeroing position positioning hole, and a dynamometer idle state positioning hole.

[0091] In an exemplary embodiment, when the fixing plate 109 is fixed to the positioning hole of the flexible connection deformation stress detection position, the dynamometer 108 measures the deformation stress of the flexible connection 103 .

[0100] In an exemplary embodiment, the limit block 114 is used to limit the rotation angle of the rotating member 104, that is, to avoid mechanical cracks when the soft connection 103 rotates with the rotating member 104; it can be understood that when the rotating member 104 is squeezed by the upward movement of the conduction rod 112 and rotates upward and contacts the limit block 114, the rotating member 104 cannot continue to rotate upward. At this time, the deformation stress of the soft connection 103 defaults to the maximum deformation stress of the soft connection 103.

[0101] In an exemplary embodiment, if the rotating member 104 breaks through the restriction of the limiting block 114 and continues to rotate upward, the flexible connection 103 will be mechanically damaged.
