[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0023] Example 1:
[0024] like Figure 1 As shown in Figure 2, a folding test fixture for enameled wire includes a fixing plate 1 and a bending plate 2. The fixing plate 1 includes an arc-shaped part and a horizontal part. A rotating shaft 3 is inserted through the center of the arc-shaped part. A cover plate is provided at the end of the bending plate 2 and is sleeved on the rotating shaft 3. The fixing plate 1 is arranged parallel to the horizontal part. The fixing plate 1 is provided with a fixing unit, and the bending plate 2 is provided with an adjustment unit. The fixing unit is used to fix one end of the enameled wire to the fixing plate 1, and the adjustment unit is used to limit the other end of the enameled wire to the bending part.
[0025] In this embodiment, the enameled wire folding test fixture uses a fixing unit and an adjustment unit to press both ends of the enameled wire 9 onto the fixing plate 1 and the bending plate 2. The tester controls the bending plate 2 to rotate around the fixing plate 1, so that the enameled wire is folded in half, and the bent part forms an arc-shaped structure around the arc-shaped part, which meets the requirement that the folded part is arc-shaped and the two ends are parallel.
[0026] like Figure 3As shown, the fixing unit includes a fixing frame 6, which is U-shaped. A fixing bolt 8 is threaded onto the top of the fixing frame 6, and a clamping plate 10 is provided at the end of the fixing bolt 8. The clamping plate 10 presses the enameled wire 9 against the fixing plate 1. When clamping the enameled wire 9, it is only necessary to tighten the fixing bolt 8 so that the clamping plate 10 moves down to press the enameled wire 9, which can fix the enameled wire 9 and the fixing frame 6 and prevent the fixing frame 6 and the enameled wire 9 from moving.
[0027] like Figure 4 As shown, the adjustment unit includes a sliding frame 7, which is U-shaped. An adjusting bolt 13 is threaded onto the top of the sliding frame 7, and a sliding plate 11 is provided at the end of the adjusting bolt 13. The sliding plate 11 is located above the enameled wire 9, and the sliding plate 11 slides with the enameled wire 9. Since the enameled wire 9 needs to be bent at the arc section, the enameled wire 9 will inevitably slide on the bending plate 2. Therefore, when clamping the enameled wire 9, the adjusting bolt 13 is rotated so that the sliding plate 11 fits against the enameled wire 9, allowing the sliding plate 11 to slide with the enameled wire 9.
[0028] Both sides of the fixed plate 1 and the bent plate 2 are provided with sliding grooves 4, and sliders 5 are slidably fitted in the sliding grooves 4. The sliders 5 are fixed to the sliding frame 7 or the fixed frame 6.
[0029] The sliding plate 11 has a number of balls 12 evenly distributed on the side facing the enameled wire 9.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
