The measuring range is as follows: up to 30N, sensitivity: can reach 0.03N.
In this embodiment, the integrated optical fiber fixture integrates the optical fiber clamps 2 and the strain gauges 3, and the strain gauges 3 and at least two optical fiber clamps 2 are sequentially arranged and fixed on the bracket 1 in a straight line, which corresponds to the coaxial arrangement of the strain gauges 3 and the at least two optical fiber clamps 2. Because the optical fiber is in a straight line state and is a core condition for accurately measuring the stress applied to the optical fiber, the optical fiber is ensured to be maintained in the straight line state in the processing process by the design, the production quality of the FBG is improved, the processing precision of the optical fiber is ensured, the stress meter 3 can accurately measure the stress of the optical fiber in real time, and the stress meter is particularly important for the application of the FBG in the aspect of stress sensing.
Further, the integrated optical fiber clamp body in the present embodiment includes a clamping plate 202 and a fixing base 201 hinged to the clamping plate 202;
The fixing seat 201 is mounted on the bracket 1, and a first fixing groove is formed on the surface of the clamping plate 202 opposite to the optical fiber;
When the clamping plate 202 rotates relative to the fixing base 201 to be parallel to the fixing base 201, the first fixing groove on the clamping plate 202 fixes the optical fiber on the surface of the fixing base 201.
It should be noted that after the optical fiber is fixed on the stress meter 3, an operator applies a certain stress to the optical fiber in the first horizontal direction, when the stress on the stress meter 3 meets the requirement, the operator drives the clamping plate 202 to rotate relative to the fixing seat 201 until the clamping plate is parallel to the fixing seat 201, and at this time, the first fixing groove on the clamping plate 202 fixes the optical fiber on the surface of the fixing seat 201, so as to avoid the optical fiber from displacement.
Further, the clamping plate 202 in this embodiment is provided with a first magnetic attraction portion, and the fixing seat 201 is provided with a second magnetic attraction portion attracted to the first magnetic attraction portion;

The pressing piece 5, the stress gauge 3 and at least two optical fiber clamps 2 are fixed on the bracket 1 in a straight line.
It should be noted that, since a microscope lens (generally, a 1.4NA oil lens is used) is used in the processing process, the fiber lens applies a stress perpendicular to the optical fiber, so that the optical fiber is bent, and the processing accuracy of the optical fiber is further affected. In order to overcome the above-mentioned problem, in this embodiment, by providing the pressing piece 5 on the bracket 1, the pressing piece 5 presses the optical fiber, so as to limit the displacement of the optical fiber under the stress of the microscope lens, and ensure the processing precision of the optical fiber.

Further, in this embodiment, an elastic arm 7 is further connected to one side of the pressing piece 5, and the elastic arm 7 is mounted on the bracket 1;
the resilient arms 7 tend to urge the abutment piece 5 downwards towards the optical fibre.
It should be noted that, through the above design, the elastic arm 7 can drive the pressing piece 5 to continuously press the optical fiber, so as to avoid the displacement of the optical fiber in the processing process.
