ことができる。(b) Prior Art As this type of extensometer, one in which a pair of levers 1 are connected to a main body 2 as shown in FIG. 1 is generally used. When measuring the elongation between the gauge points of the test piece 3, the tip of each lever 1 is fixed to the test piece 3, the elongation between the gauge points of the test piece 3 is taken out by each lever 1, and the elongation between the gauge points of the test piece 3 is taken out by the main body 2. As is well known, it is measured by The gauge distance of the test piece 3 corresponds to the distance GL between each lever 1. In order to set the gauge distance of the test piece 3, that is, the distance GL between each lever 1, conventionally, as shown in FIG. screw together. and each lever 1 of the extensometer
was inserted into each jig main body 5, each operating screw 6 was tightened, and each lever 1 was sandwiched between the rod 4 and each operating screw 6. The distance GL between each lever 1 is determined by the length of the rod 4. Therefore, if the tips of the levers 1 are fixed to the test piece 3 as they are, a constant gauge distance corresponding to the distance GL between the levers 1 can be obtained. After fixing, loosen each operation screw 6 and remove the jig main body 5 from the lever 1. Then, the elongation between the gauge points of the test piece 3 can be taken out using each lever 1, and the elongation can be measured using the main body 2. can do.

もある。 However, the material testing machine has a pair of chucks 7 for gripping both ends of the test piece 3. As is well known, the chuck 7 applies an axial load to the test piece 3 to perform a material test.
Therefore, when fixing the tip of each lever 1 to the test piece 3, the rod 4, jig main body 5, and operating screw 6 must be inserted between the chucks 7. Each operating screw 6 must be operated between the chucks 7.
Conventionally, since each operating screw 6 protrudes in the axial direction of the test piece 3, especially when the distance between the chucks 7 is small,
It was not easy to insert each operation screw 6 between each chuck 7 and operate between each chuck 7. In some cases, each operation screw 6 cannot be inserted and operated, and the gauge distance of the test piece 3 cannot be set.

FIG. 4 shows an embodiment of this invention. The gauge distance of the test piece 3 is set by a jig having a main body 8. The main body 8 includes a pair of end walls 9 facing each other at a distance, and a side wall 1 connecting one side edge of each end wall 9.
It is made of 0 and has a substantially U-shaped cross section. Further, a pair of lever pressing metal fittings 11 are arranged so as to face the inner surface of each end wall 9 of the main body 8, and each lever 1 of the extensometer is inserted between the inner surface of each end wall 9 and each pressing metal fitting 11. Each pressing member 11 is operated by an operating shaft 12 and a wedge 13. The operating shaft 12 passes through the side wall of the main body 8 and projects to the outside. The wedge 13 is arranged between the respective pressing fittings 11 and connected to the operating shaft 12. The pressing fittings 11 are elastically urged toward each other by a spring 14 and are kept in contact with the inclined surface of the wedge 13.

ー１間の距離GLに対応する。 In this gage distance setting jig, each pressing fitting 11 is guided by the inner surface of the side wall 10 of the main body 8, and is pressed against each lever 1 of the extensometer by the elasticity of the spring 17 and the wedge action of the wedge 13. . Each lever 1 is connected to the inner surface of each end wall 9 and each pressing fitting 1
It is sandwiched between 1. Therefore, each lever 1
are kept at a constant distance from each other. The distance GL therebetween is determined by the spacing between each end wall 9.
Therefore, if the tip of each lever 1 is fixed to the test piece 3 as it is, the tip of each lever 1 will be fixed with a constant distance between the gauges. The distance between targets corresponds to the distance GL between each lever 1.

にワンタツチで取り外すことができる。 In order to remove the jig main body 8 from the lever 1, it is sufficient to hook the index finger and middle finger on the finger stop 16 and press the pressing portion 15 of the operating shaft 12 with the thumb. The operating shaft 12 is displaced in the axial direction against the elasticity of the spring 17,
The wedge 13 is displaced integrally with the operating shaft 12. Therefore, the wedge action of wedge 13 is released,
Each pressing fitting 11 is pulled by a spring 14 and separated from each lever 1. Therefore, when the jig main body 8 is pulled as it is, each lever 1 is pulled out from the inner surface of each end wall 10 and each pressing fitting 11. Therefore, the jig main body 8 can be easily removed with one hand.

に挿入することにも、問題はない。 With this jig, the main body 8 can be removed from the lever 1 of the extensometer simply by displacing the operating shaft 12 in the axial direction, so the gauge distance of the test piece 3 can be easily set. Since the operating shaft 12 passes through the side wall 10 of the main body 8 and protrudes in a direction perpendicular to the axial direction of the test piece 3, there is no problem in operating the operating shaft 12 even if the distance between the chucks 7 of the material testing machine is small. There is no problem in inserting the entire jig between the chucks 7 while it is attached to the lever 1.
また、この治具は、ワンタツチで伸び計のレバ
