[0029] like Figure 1As shown, the test bench 1 as a whole is a semi-cylindrical structure, and the semi-cylindrical structures are arranged in parallel, so that the top of the test bench 1 is a planar structure, and the bottom is a semicircular structure. The test area 101 is opened on the planar structure of the test bench 1 and is located at the center. The two ends of the test bench 1 are also planar structures, so that the angle adjustment components are arranged at the two ends of the test bench 1, thereby ensuring that the test bench 1 rotates along the angle adjustment components at the two ends.
[0030] In some possible embodiments, the overall structure of the test bench 1 may be other structures, and it is only necessary to ensure that the top of the test bench 1 is a planar structure.
[0031] Please refer to Figure 1 and Figure 3 The rotating assembly includes a slot 8 opened on both sides of the test bench 1 and a rotating member 7 rotating inside the slot 8. One side of the rotating member 7 is connected to the test bench 1 through a bearing. The slot 8 is opened in a circular shape. The rotating member 7 is arranged at the center of the slot 8. The shape of the slot 8 is set to be a ring structure.
[0032] like Figure 1 and Figure 3 As shown, the card slot 8 is opened at both ends of the test bench 1 and is located at the center position as much as possible. A groove adapted to the rotating member 7 is opened inside the card slot 8. A bearing is arranged inside the groove so that the bearing inside the groove is connected to the rotating member 7. In addition, a connecting member 9 is arranged inside the groove so that the groove is isolated into an annular structure, which is convenient for subsequent fixing components to fix the test bench 1.
[0033] Please refer to Figure 1 and Figure 5 The fixing assembly includes a connecting member 9 fixedly arranged on one side of the rotating member 7 and a clamping member 10 threadedly connected to one side of the connecting member 9 , and one end of the connecting member 9 is located at the outer edge of the clamping slot 8 .
[0034] like Figure 1 and Figure 5 As shown, one end of the connecting member 9 is connected to one side of the rotating member 7, and one side of the other end is fitted with one side of the test bench 1, so that the connecting member 9 as a whole passes horizontally above the slot 8, thereby ensuring that one end of the clamping member 10 connected to the connecting member 9 corresponds to the slot 8.
[0035] Please continue to read Figure 1 and Figure 5 One end of the clamping member 10 threadedly connected to the connecting member 9 is located inside the clamping groove 8, and the clamping member 10 is configured as a bolt.
[0036] like Figure 1 and Figure 5As shown, a screw hole matching the bolt is opened on one side of the connecting member 9, so that the bolt is connected to the screw hole, ensuring that when the test bench 1 is fixed, the bolt is rotated and inserted into the slot 8 to support the test bench 1 and fix the test bench 1 by friction.

The upper and lower ends of the support rod are oblate, and the bottom is connected to the base 11 to increase the force-bearing area and support the test bench 1 more stably.
[0039] Please continue to read Figure 1 and Figure 2 Movable parts 4 are inserted into both sides of the inner wall of the test area 101, one end of the movable part 4 is fixedly provided with a fixing part 3 and the outer surface is sleeved with a spring 5, the two ends of the spring 5 are respectively fixedly connected to the fixing part 3 and the test bench 1, and a movable hole is opened at the position where the movable part 4 is inserted into the inner wall of the test area 101.
[0040] like Figure 1 and Figure 2 As shown, the movable parts 4 on the inner wall of the test area 101 can be arranged on two of the four sides, but they need to be arranged corresponding to each other. The two are symmetrical with the center of the test bench 1 to fix the module, and the spring 5 and the movable hole can ensure that the fixing part 3 can be extended and retracted, so that modules of different widths can be arranged between the two fixing parts 3, which is convenient for fixing modules of different widths.
[0041] Please continue to read Figure 1 and Figure 2 The fixing member 3 is in a semi-annular structure as a whole, and one end of the fixing member 3 close to the center of the test bench 1 is in a concave structure.
[0042] like Figure 1 and Figure 2 As shown, the arc-shaped structure of the fixing member 3 can prevent sliding when the module is clamped between two fixing members 3, and the fixation is more stable.
[0043] Please continue to read Figure 1 and Figure 2 Both sides of the inner wall of the test area 101 are rotatably connected with a pressing piece 2.
[0044] like Figure 1 and Figure 2As shown, after the module is placed into the test area 101, the bottom of the pressing piece 2 is located below the module. When the module needs to be taken out, the pressing piece 2 can be rotated to lift the module for easy removal.
[0045] Specifically, the working principle and process of the utility model are as follows: when the tilt angle of the module needs to be adjusted, the test table 1 can be pushed to rotate the test table 1 along the center point of the rotating member 7, so that the module can be rotated to a suitable tilt angle, and when it needs to be maintained at this angle, the clamp 10 is rotated to make the clamp 10 contact with the test table 1 and press the test table 1, so as to fix the test table 1 and prevent the test table 1 from automatically flipping over.
[0046] The utility model has the following advantages: after the module is fixed, the module can be easily turned over so that the module can be rotated to a suitable tilt angle.
[0047] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
