Background Art:

The structure of the current fiber strength tester includes a force sensor, a first connecting rod, an upper clamp, and a lower clamp. Figure 2 shows an application example in this environment. The lower clamp is connected to a moving platform via a second connecting rod. The fiber material is directly fixed on the upper and lower clamps. During the experiment, the moving platform moves to measure the strength of the fiber.

However, this structure has the following problems:

1. This structure uses online sample preparation, clamping a single fiber directly between the upper and lower clamps. However, it cannot perform online sample preparation for very fine micro-nano fibers with low strength;

2. The sensor used in this structure has a large measurement range and low accuracy, making it suitable only for measuring the strength of conventional fibers. However, for micro-nano fiber materials with extremely fine fineness and low strength, the accuracy of this sensor is insufficient to obtain accurate data, which hinders the research on the physical properties of micro-nano fiber materials;

3. The force sensors used in this structure have a large range but low precision; for force sensors with a small range and low precision, using the online sample preparation method can easily damage the sensor, affecting the accuracy of the data measured by the instrument.

Technical implementation elements:

In view of the disadvantages of the prior art described above, the object of the present invention is to provide a force measurement module for measuring the strength of micro-nano single fiber materials, which can measure force more accurately.

To achieve the above object and other related objects, the present invention provides a force measurement module for measuring the strength of micro-nano single fiber materials, comprising a force sensor, an upper connector connected to the force sensor, a lower connector connected to the upper connector, an upper clamp connected to the lower connector, and a lower clamp used in conjunction with the upper clamp.

1. The upper connector is an upper hook, the lower connector is also a lower hook, and the upper hook and the lower hook have the same shape and size.

2. The fiber material is a single fiber, and its dimensions are at the micron or nanometer scale.

3. Both ends of the upper hook and the lower hook are provided with U-shaped bends, which connect the two together.

4. The lower hook and the upper clamp are fixedly connected to each other via threads.

In actual use, a nanofiber specimen stage is connected between the upper clamp and the lower clamp, and the lower clamp is connected to a motion platform via a connecting rod. During the experiment, the motion platform moves to measure the tensile strength of the micro-nanofiber material.

As described above, the force measurement module for measuring the tensile strength of micro-nanofiber single-fiber materials of the present invention has the following beneficial effects:
