のチャック１を載置して測定にかけることになる。The chuck 1 according to the present invention includes an upper chuck 1a and a lower chuck 1b, and grooves 1c and 1d are formed at positions where these two chucks face each other.
An adjusting pin 2 is sandwiched between these grooves 1c and 1d. The adjusting pin 2 can be replaced depending on the diameter of the fibrous sample M.
That is, the adjustment pin 2 is set so that the angle α between the direction of the sample M to be measured at that time and the end surface 1e of the chuck 1 is substantially a right angle.
Exchange. This is, as shown in FIG.
This is to ensure that the sample is placed perpendicular to the detection rod 12 and Next, a pin 3 is implanted in one of the upper and lower chucks, and a hole (window) 4 for loosely inserting the pin 3 is formed in the other. As can be seen from the drawing, the pin 3 is for winding a fibrous sample M of an arbitrary length to apply tension. Reference numeral 5 denotes a screw for firmly fixing the sample between the upper and lower chucks 1a and 1b after the sample is sandwiched between the upper and lower chucks 1a and 1b. As shown in FIG. 3, the sample held by the chucks 1 and 1 according to the present invention is subjected to measurement by placing one of the chucks 1 on a detection rod 12 in a sample support tube 11. .

もより正確となる。[0008] The configuration of the sample mounting chuck for thermomechanical analysis according to the present invention is as described above. Next, its operation will be described. Conventionally, with a chuck that mounts a sample at one location, the distance between the tip of the chuck and the screw is short, so a longer sample cannot be set between the upper and lower chucks, and of course, an appropriate tension can be added to the sample even when tightening the screw. Did not. However, if the chuck 1 according to the present invention is configured as described above, the upper and lower chucks 1a,
1b is provided with a pin 3 implanted on one side and a hole (window) 4 for fitting the pin 3 on the other side, so that the sample can be wound around the pin 3 and taken out in the lateral direction of the chuck. A sample can be attached to a sample of a length. Of course, an appropriate tension can be applied when the screw 5 is tightened. Then, after tightening with the screw 5, the extra sample in the lateral direction may be cut, so that the sample becomes very easy to attach, and at the same time, the intended sample length when attaching the chuck is obtained. Further, in the chuck 1 according to the present invention, since the adjustment pin 2 corresponding to the diameter of the sample can be selected and the angle between the sample and the chuck end can be set to a right angle and attached to the sample support tube, the measurement becomes more accurate.
