The flexible waveguide is divided into a twistable flexible waveguide and a non-twistable flexible waveguide, and at present, the twistable flexible waveguide is superior in production process technology, mainly made of precision winding equipment, and has the characteristics of high production efficiency, low cost and the like. The untwistable flexible waveguide mostly adopts the processes of expanding mould or electroforming and the like, and has high production cost and low efficiency. No matter what kind of technology production, the service environment of soft waveguide is all very complicated, needs on the one hand to shake for a long time and play the cushioning effect and need to possess some mechanical properties, on the other hand needs the bending deformation of different degrees according to the condition of hard waveguide system space structure. The existing main length specifications of the soft waveguide comprise length specifications of 1200mm, 1000mm, 900mm, 600mm and the like, and the specifications of the hard waveguide corresponding to the soft waveguide are various. In order to meet the electrical performance test requirements of the flexible waveguides with different specifications and different application scenes, the embodiment of the application provides the flexible waveguide electrical performance test clamping device, the universality of the clamp is considered, the clamping device is formed by assembling a modular structure, and the electrical performance tests of the twistable waveguide limit torsion (only the twistable flexible waveguide needs to be tested), the E-surface limit bending and the H-surface limit bending (the flexible waveguide can be used universally) are realized. That is to say, the clamping device provided by the embodiment of the present application mainly tests the electrical performance value of the flexible waveguide under various extreme bending and extreme torsion conditions.

It should be noted that, when electrical performance values of the flexible waveguides of different product models are tested in a bending or torsion state, the E-plane bending radius, the H-plane bending radius and the axial torsion angle are different. In the embodiment of the present application, twisted waveguides of three different product models are exemplified, and the parameters of the three twisted waveguides, such as the bending radius and the torsion angle, are shown in table 1 below.

				H surface radius of curvature (mm)	200	152	120
E surface radius of curvature (mm)	100	76	66
