In this embodiment, the clamping members 2 clamp at both ends of the special-shaped part 3 along the X-direction, the supporting members 4 support the bottom of the special-shaped part 3 along the Z-direction, and the limiting member 5 abuts against one side of the special-shaped part 3 along the Y-direction, so that the special-shaped part 3 can be clamped from all directions, achieving a good clamping effect, reducing risks during the test process, and improving inspection efficiency.

[0027] See also Figure 1 As shown, in some embodiments, a bearing 7 is installed in the base 1, a screw 6 is installed in the bearing 7, the screw 6 is passed through the base 1, and the clamping member 2 is connected to the screw 6. In this embodiment, the screw 6 can rotate in the bearing 7, and at the same time drive the two clamping members 2 to move toward or away from each other, which is convenient for clamping the special-shaped member 3 during use, has a good clamping effect, and has a wide range of applications.

[0028] See also Figure 1 As shown, in some embodiments, the bearing 7 is located between the two clamping members 2, and a plane 71 is provided on the top of the bearing 7 for supporting the special-shaped member 3 along the Z direction. In this embodiment, by arranging the bearing 7 between the two clamping members 2, the special-shaped member 3 can be placed on the top plane 71 of the bearing 7 to play a supporting role, further ensuring the stability of the special-shaped member 3 during the test.

[0029] See also Figure 1As shown, in some embodiments, the front end of the screw 6 extends out of the base 1, and a handle 8 is installed on the extended end. In this embodiment, by providing the handle 8, the screw 6 can be rotated by holding the handle to adjust the distance between the two clamping parts 2, which is convenient for adjustment and has a better clamping effect.

[0030] See also Figure 1 As shown, in some embodiments, the support member 4 may include: a support seat 41, which is fixed on the mounting seat 21; a support bolt 42, which is rotatably mounted on the support seat 41, and the axis of the support bolt 42 is perpendicular to the top surface of the base 1. In this embodiment, the support bolt 42 is used to support the special-shaped part 3 along the Z direction. The support bolt 42 can be rotated to adjust the height, so that it can be adjusted to a suitable height according to the shape of the special-shaped part, and cooperated with the clamping parts in other directions to achieve a better clamping effect on the special-shaped part 3.

[0031] See also Figure 1 As shown, in some embodiments, the limiting member 5 may include: a limiting seat 51, which is installed on the outside of the mounting seat 21; a limiting bolt 52, which is rotatably installed on the limiting seat 51, and the axis of the limiting bolt 52 is parallel to the top surface of the base 1. In this embodiment, the limiting member 5 can be installed on one side of the clamping member 2, or a limiting member 5 can be installed on each side. The limiting bolt 52 is used to support the special-shaped member 3 along the Y direction. The limiting bolt 52 can be rotated to adjust the height, so that it can be adjusted to a suitable height according to the shape of the special-shaped member. In combination with clamping members in other directions, the clamping effect of the special-shaped member 3 is better.

[0032] See also Figure 1 As shown, in some embodiments, a clamping groove 23 is provided on the side where the clamping blocks 22 of the two clamping members 2 are close to each other, and the clamping groove 23 is V-shaped. In this embodiment, by providing the V-shaped groove, the two ends of the special-shaped member 3 can be restricted in the V-shaped groove, thereby further playing a limiting role in the Z direction, and the clamping effect is better, ensuring the stability of the special-shaped member 3 during the test.

[0033] See also Figure 1 As shown, in some embodiments, a fixing seat 24 is provided on one side of the clamping block 22, and a bolt hole is opened on the fixing seat 24. In this embodiment, a bolt can be installed in the bolt hole. When in use, after the clamping member 2 is moved to the required position, the clamping member 2 can be fixed with a bolt to avoid loosening, thereby further improving the clamping effect.

[0034] See also Figure 1As shown, in some embodiments, the mounting seat 21, the clamping block 22 and the fixing seat 24 are integrally formed. In this embodiment, the entire clamping member 2 is formed into a whole through the integrally formed design of each component, thereby ensuring the stability of the clamping member 2 and better clamping the special-shaped parts.

[0035] See also Figure 1 As shown, in some embodiments, the limit seat 51 is rotatably mounted on the mounting base 21 via an adjustment bolt. In this embodiment, the limit seat 51 can rotate around the adjustment bolt, so that the angle of the limit seat 51 can be adjusted according to the shape of the special-shaped part, thereby more accurately limiting the position in the Y direction and further improving the clamping effect.
