Then the sole and the fixture are placed on the bending tester for bending test.

[0005] A further feature of this invention is that an auxiliary clamping plate is fixedly provided on the surface of the mounting frame opposite to the through hole.

[0006] By adopting the above technical solution, since an auxiliary clamping plate is fixedly provided on the surface opposite to the through hole in the mounting frame, the stability of shoe sole clamping can be further improved.

[0007] A further feature of this invention is that a limiting protrusion is provided at the connection between the front fixing plate and the rear fixing plate, and the end face of the limiting protrusion is an angled bevel.

[0008] By adopting the above technical solution, since a limiting protrusion is provided at the connection between the front fixing plate and the rear fixing plate, and the end face of the limiting protrusion is an angled slope, the bending angle of the sole can be limited, thus preventing excessive bending.

[0009] A further feature of this invention is that the front-end fixing plate is provided with several anti-slip textures.

[0010] By adopting the above technical solution, since the front-end fixed clamp plate is provided with several anti-slip textures, the clamp can be installed more firmly and stably on the bending machine.

[0011] A further feature of this invention is that a locking groove is provided on the rear fixed clamp plate at a position aligned with the through hole, and the length of the locking groove matches the installation slide groove.

[0012] By adopting the above technical solution, since a locking groove is provided at the position of the rear fixed clamp plate aligned with the through hole, and the length of the locking groove matches the installation slide groove, the stability of the locking screw when locking can be improved.
