[0050] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0051] Figure 1 is a structural schematic diagram of a support device provided by an embodiment of the present disclosure. Figure 1 The support device includes: a base 10, a support rod 20, a plurality of contact rods 30 and an adjustment structure 40. The support rod 20 is located on the base 10. The plurality of contact rods 30 are parallel to the support rod 20 and are arranged in an arc shape around the support rod 20, and the side surfaces of the plurality of contact rods 30 provide a bearing surface for bearing the flexible plate-like structure 200. The adjustment structure 40 connects the support rod 20 and the contact rod 30, and the adjustment structure 40 is configured to adjust the distance between the contact rod 30 and the support rod 20 to adjust the curvature of the bearing surface. The adjustment structure 40 may adjust the minimum spacing between the contact rod 30 and the support rod 20, or the spacing between the center line of the contact rod 30 and the center line of the support rod 20.

[0052] In this implementation, the multiple contact rods 30 are parallel to the support rod 20 and the multiple contact rods 30 are arranged in an arc shape around the support rod 20. The side surfaces of the multiple contact rods 30 can form an approximately arc-shaped bearing surface for supporting the flexible plate-like structure 200. The bearing surface takes the center line of the support rod 20 as the center line, and the radius of the support rod 20, the minimum spacing between the contact rod 30 and the support rod 20, and the diameter of the contact rod 30 are the sum of the radius of the bearing surface. Since the radius is negatively correlated with the curvature of the bending, that is, the larger the radius of the bearing surface, the smaller the curvature of the bending, and the smaller the radius of the bearing surface, the larger the curvature of the bending. Therefore, by adjusting the minimum spacing between the contact rod 30 and the support rod 20 by adjusting the structure 40, the curvature of the bending of the bearing surface can be adjusted. In the process of detecting the performance of the flexible plate-like structure 200 under different bending curvature states, the flexible plate-like structure 200 is attached to the bearing surface, and the bending curvature of the bearing surface is the same as the bending curvature of the flexible plate-like structure 200. Therefore, in the process of detecting the performance of the flexible plate-like structure 200 under different bending curvature states, a supporting device can be used to support the flexible plate-like structure 200 under different bending curvature states, thereby reducing costs. In the process of detection, there is no need to replace the supporting device, thereby improving work efficiency.

[0053] In the disclosed embodiment, when the flexible plate-like structure 200 is attached to the bearing surface, the flexible plate-like structure 200 can be attached to the contact rod 30 to ensure the stability of the flexible plate-like structure 200 during the detection process and avoid affecting the detection accuracy.

[0054] In the embodiment of the present disclosure, the center line of the contact rod 30 and the center line of the support rod 20 are parallel to each other.

[0055] Figure 2 is a schematic diagram of a combination of a support rod, a contact rod and an adjustment structure provided by an embodiment of the present disclosure. Figure 1 and Figure 2 The adjustment structure 40 includes two hinged rings 401, a plurality of first connecting rods 402 and a plurality of second connecting rods 403. The two hinged rings 401 are spaced apart on the support rod 20, and at least one hinged ring 401 is configured to be movably located on the support rod 20, and the moving direction is the same as the length direction a of the support rod 20. The plurality of first connecting rods 402 correspond to the plurality of contact rods 30 one by one, one end of the first connecting rod 402 is hinged to the corresponding contact rod 30, and the other end of the first connecting rod 402 is hinged to one hinged ring 401. The plurality of second connecting rods 403 correspond to the plurality of contact rods 30 one by one, one end of the second connecting rod 403 is hinged to the corresponding contact rod 30, and the other end of the second connecting rod 403 is hinged to another hinged ring 401.

[0056] Since the first link 402 is hinged to the hinge ring 401, the first link 402 is hinged to the contact rod 30, the contact rod 30 is hinged to the second link 403, the second link 403 is hinged to another hinge ring 401, and at least one hinge ring 401 can move on the support rod 20 along the length direction a of the support rod 20. When it is necessary to adjust the curvature of the bearing surface, the position of at least one hinge ring 401 on the support rod 20 is adjusted so that the distance between the two hinge rings 401 changes, and the first link 402 and the second link 403 rotate around the hinge axis, so that the angle between the first link 402 and the support rod 20 and the angle between the second link 403 and the support rod 20 change, so that the distance between the contact rod 30 and the support rod 20 changes, and the radius of the bearing surface is adjusted. In the process of detecting the performance of the flexible plate-like structure 200 under different curvature states, the curvature of the flexible plate-like structure 200 is conveniently adjusted.

[0057] For example, in Figure 2 In the illustrated embodiment, both hinge rings 401 are movably located on the support rod 20. The adjustment structure 40 further includes: two adjustment rings 404 and a stopper 405, wherein the two adjustment rings 404 are spaced apart and located on the support rod 20 and are threadedly connected to the support rod 20. The two hinge rings 401 are located between the two adjustment rings 404. The stopper 405 is located on the support rod 20, and the stopper 405 is configured to limit the position of the hinge ring 401 on the support rod 20.

[0058] The adjusting ring 404 is threadedly connected to the support rod 20, and the adjusting ring 404 can be rotated to adjust the distance between the two adjusting rings 404. Since the hinge ring 401 is located between the two adjusting rings 404, when the adjusting ring 404 contacts the hinge ring 401, the position of the hinge ring 401 on the support rod 20 will change during the movement of the adjusting ring 404. At the same time, the limiter 405 is used to limit the position of the hinge ring 401 on the support rod 20. After adjusting the position of the hinge ring 401, the distance between the two hinge rings 401 remains unchanged, thereby keeping the distance between the contact rod 30 and the support rod 20 unchanged. In the process of testing the performance of the flexible plate-like structure 200 under different bending curvature states, the radius of the bearing surface will not change, and will not affect the bending curvature of the flexible plate-like structure 200, thereby avoiding affecting the test results.

[0059] The first link 402 and the second link 403 are both hinged to the hinge ring 401. When the distance between the two hinge rings 401 changes, the angle between the first link 402 and the support rod 20 and the angle between the second link 403 and the support rod 20 also change. Thus, the radius of the bearing surface is adjusted. In the process of testing the performance of the flexible plate-like structure 200 under different bending curvature states, it is more convenient to adjust the bending curvature of the flexible plate-like structure 200 by rotating the adjustment ring 404.

[0060] like Figure 2 As shown, the support rod 20 has an external thread, and the adjusting ring 404 has an internal thread, so that the adjusting ring 404 and the support rod 20 are threadedly connected.

[0061] In one implementation of the embodiment of the present disclosure, both ends of the support rod 20 have external threads, the two adjustment rings 404 have internal threads, the two adjustment rings 404 are connected to the threads of the support rod 20, and the two adjustment rings 404 can be used to adjust the distance between the two hinged rings 401.

[0062] In other implementations, one end of the support rod 20 has an external thread, one of the adjustment rings 404 has an internal thread, and the adjustment ring 404 with the internal thread is threadedly connected to the external thread at one end of the support rod 20. Another adjustment ring 404 is fixed to the other end of the support rod 20, and the distance between the two hinge rings 401 is adjusted by the adjustment ring 404.

[0063] For example, in the vertical direction, the upper end of the support rod 20 has an external thread, and the adjustment ring 404 with an internal thread is threadedly connected with the external thread of the upper end of the support rod 20. Another adjustment ring 404 is fixed to the lower end of the support rod 20.

[0064] In one implementation of the embodiment of the present disclosure, the limiter 405 is a first elastic element, both ends of which are respectively abutted against two hinge rings 401 , and the first elastic element is in a state of providing pressure to the abutted hinge rings 401 .

[0065] The first elastic element is located between the two hinge rings 401, and the first elastic element generates a force on the hinge ring 401 toward the adjustment ring 404. Since the adjustment ring 404 is threadedly connected to the support rod 20, the adjustment ring 404 limits the movement of the hinge ring 401 away from the first elastic element. The position of the hinge ring 401 is limited by the first elastic element and the adjustment ring 404.

[0066] In one implementation of the disclosed embodiment, the first elastic element is a first compression spring in a compressed state. The first compression spring provides pressure to the hinge ring 401, which is more convenient. At the same time, the compression spring is easy to obtain, which reduces the cost of making the support device of the flexible plate-like structure.

[0067] In other implementations, the first elastic element may also be a first elastic sheet in a compressed state, and the first elastic sheet may also provide pressure to the hinge ring 401 .

[0068] In other implementations of the disclosed embodiments, the distance between the two hinge rings 401 may also be limited by other methods. For example, the support rod 20 has a plurality of through holes, the extension direction of the through holes is perpendicular to the length direction a of the support rod 20, the hinge ring 401 is adjusted to between the two through holes, and then pins are respectively inserted into the two through holes to limit the distance between the two hinge rings 401.

[0069] In other implementations of the disclosed embodiment, the adjustment structure includes a retractable sleeve 406, Figure 3 is a combination diagram of a sleeve and a support rod provided in an embodiment of the present disclosure. Figure 3 The sleeve 406 is sleeved on the support rod 20, and the telescopic direction of the sleeve 406 is the same as the length direction of the support rod 20. The two hinge rings 401 are respectively fixedly connected to the two ends of the sleeve 406. During the detection process, the telescopic length of the telescopic sleeve 406 is adjusted, thereby adjusting the distance between the two hinge rings 401.

[0070] Exemplarily, the retractable sleeve 406 includes a first cylinder 461 and a second cylinder 462, both of which are coaxially sleeved on the support rod 20, one end of the first cylinder 461 is located in the second cylinder 462, and one end of the second cylinder 462 away from the first cylinder 461 is fixedly connected to the support rod 20. The first cylinder 461 has a plurality of cylinder through holes 463, and the support rod has a plurality of through holes, and the extension directions of the cylinder through holes 463 and the through holes on the support rod are perpendicular to the length direction a of the support rod 20. When adjusting the telescopic length of the sleeve 406, adjust the position of one end of the first cylinder 461 inside the second cylinder 462, and at the same time make a cylinder through hole 463 on the first cylinder 461 connected with a through hole on the support rod, and then insert a pin into the cylinder through hole 463 and the through hole on the support rod respectively to fix the first cylinder 461, thereby adjusting the telescopic length of the sleeve 406, that is, adjusting the distance between the two hinge rings 401.

[0071] Figure 4 is a schematic diagram of the structure of a hinge ring provided by an embodiment of the present disclosure. Figure 4 The hinge ring 401 is in a circular ring shape. The center of the hinge ring 401 has a hinge ring through hole 411 that penetrates the upper and lower end surfaces of the hinge ring 401. The support rod passes through the hinge ring through hole 411, so that the hinge ring 401 is sleeved on the support rod 20. The outer circular side wall of the hinge ring 401 has a plurality of hinge blocks 413, and the plurality of hinge blocks 413 are evenly spaced around the hinge ring through hole 411. A gap 412 is formed between each two adjacent hinge blocks 413. The hinge blocks 413 have hinge block through holes 414, and the hinge blocks 413 are arranged one by one corresponding to the contact rods 30.

[0072] Figure 5is a schematic diagram of the structure of a first connecting rod provided in an embodiment of the present disclosure, see Figure 5 One end 421 of the first connecting rod 402 has two first ear plates 422 arranged at intervals, and the two first ear plates 422 have first ear plate through holes 423 perpendicular to the length direction of the first connecting rod 402, and the center lines of the two first ear plate through holes 423 are on the same straight line. The gap between the two first ear plates 422 is greater than the thickness of the hinge block 413.

[0073] The hinge block 413 is placed in the gap between the two first ear plates 422, so that the center lines of the hinge block through hole 414 and the two first ear plate through holes 423 are in the same straight line, and then the hinge shaft passes through the first ear plate through hole 423, the hinge block through hole 414 and the first ear plate through hole 423 in sequence. The first connecting rod 402 is hinged to the hinge ring 401. The gap between the two first ear plates 422 is larger than the thickness of the hinge block 413, so that one end 421 of the first connecting rod 402 can be easily rotated.

[0074] The other end 424 of the first connecting rod 402 also has two spaced second ear plates 425 . The two second ear plates 425 have second ear plate through holes 426 perpendicular to the length direction of the first connecting rod 402 . The center lines of the two second ear plate through holes 426 are on the same straight line.

[0075] Figure 6 is a schematic diagram of the structure of a contact rod provided by an embodiment of the present disclosure. Figure 6 , both ends of the contact rod 30 have third ear plates 301, and the third ear plates 301 have third ear plate through holes 302 perpendicular to the length direction of the contact rod 30. The third ear plates 301 are located in the gap between the two second ear plates 425, and the hinge axis passes through the second ear plate through holes 426, the third ear plate through holes 302, and the second ear plate through holes 426 in sequence. The diameter of the hinge axis is smaller than the third ear plate through holes 302 and the second ear plate through holes 426, so that both the first connecting rod 402 and the contact rod 30 can rotate around the hinge axis, thereby realizing the hinge connection between the first connecting rod 402 and the contact rod 30.

[0076] In the embodiment of the present disclosure, the second connecting rod 403 can be hinged to the hinge ring 401 and the contact rod 30 respectively in the same manner.

[0077] In one implementation of the embodiment of the present disclosure, the length L1 of the contact rod 30 is between 5 cm and 10 cm.

[0078] In the disclosed embodiment, the flexible plate-like structure 200 can be a detection device for detecting the luminous effect of a pixel. The detection device is a small display panel. The luminous effect of a pixel is determined by detecting the detection device, and pixels with better luminous effects are applied to the display panel to ensure the display effect of the display panel produced subsequently. The size of the detection device is small, and the length L1 of the contact rod 30 is limited, so that the size of the bearing surface formed by the contact rod 30 is sufficient to carry the detection device, thereby ensuring the accuracy of the detection.

[0079] When the supporting device is used to support a detection device for detecting the luminous effect of a pixel, the detection device has a luminous area, and the length L1 of the contact rod 30 should be greater than the width of the luminous area in the detection device, to ensure that when the performance of the detection device under different bending curvatures is detected, the display device where the luminous area is located can be bent to ensure the accuracy of the detection.

[0080] Of course, in other implementations, the supporting device may be scaled up in proportion so that the supporting device can support a large-sized flexible display panel.

[0081] In the embodiment of the present disclosure, the length of the support rod 20 is greater than the length of the contact rod 30 , and the length L3 of the first connecting rod 402 is equal to the length L3 of the second connecting rod 403 .

[0082] Figure 7 Schematic diagram of the connection relationship between a support rod, a contact rod, a first connecting rod and a second connecting rod provided by an embodiment of the present disclosure. Figure 7 The contact rod 30, the first connecting rod 402, the second connecting rod 403 and the support rod 20 form an isosceles trapezoid. The contact rod 30 and the support rod 20 are the top and bottom sides of the isosceles trapezoid respectively, and the first connecting rod 402 and the second connecting rod 403 are the waists of the isosceles trapezoid respectively.

[0083] The minimum distance X between the support rod 20 and the contact rod 30 can be obtained by the Pythagorean theorem:

[0084]

[0085] Wherein, L1 is the length of the contact rod, L2 is the minimum distance between the two hinge rings 401, and L3 is the length of the first connecting rod.

[0086] The radius of the support rod 20, the minimum spacing between the support rod 20 and the contact rod 30, and the diameter of the contact rod 30 are the radius of the bearing surface, that is, the bending radius of the flexible plate structure that is in contact with the bearing surface. The bending curvature of the flexible plate structure can be obtained based on the relationship between the bending radius and the bending curvature.

[0087] In other implementations, the length of the first connecting rod 402 and the length of the second connecting rod 403 may also be unequal.

[0088] See again Figure 1 The support device further includes an anti-rotation structure 50 , which abuts against a side surface of at least one contact rod 30 , and the anti-rotation structure 50 is configured to prevent the plurality of contact rods 30 from rotating around the support rod 20 .

[0089] In this implementation, since the contact rods 30 are arranged in an arc shape around the support rod 20, during the process of detecting the performance of the flexible plate-like structure 200 under different bending curvature states, the contact rods 30 may rotate around the support rod 20, causing the flexible plate-like structure 200 to rotate. An anti-rotation structure 50 is arranged, and the anti-rotation structure 50 abuts against the side surface of at least one contact rod 30 to prevent multiple contact rods 30 from rotating around the support rod 20, thereby ensuring the stability of the flexible plate-like structure 200 during the process of detecting the performance of the flexible plate-like structure 200 under different bending curvature states, and preventing the rotation of the flexible plate-like structure 200 from affecting the detection result.

[0090] See again Figure 1 , the support rod 20 is slidably mounted on the base 10. The anti-rotation structure 50 includes a baffle 501 and a pressing member 502. The baffle 501 has a surface parallel to the length direction of the contact rod 30. The pressing member 502 is configured to limit the position of the support rod 20 on the base 10 so that at least one side of the contact rod 30 abuts against the surface of the stop plate baffle 501.

[0091] In this implementation, during the process of testing the performance of the flexible plate structure 200 under different bending curvature states, the clamping member 502 generates a clamping force on the support rod 20, causing the support rod 20 to move, thereby driving the contact rod 30 to move, causing the contact rod 30 to press against the surface of the limit plate baffle 501, and the friction between the side of the contact rod 30 and the surface of the limit plate baffle 501 prevents the contact rod 30 from rotating.

[0092] In an implementation of the embodiment of the present disclosure, the sliding direction of the support rod 20 is perpendicular to the length direction of the support rod 20 .

[0093] Figure 8 1 is a top view of a support device provided by an embodiment of the present disclosure. Figure 1 and Figure 8 The base 10 includes two linear guide rails 101 , and both ends of the support rod 20 are slidably connected to the two linear guide rails 101 .

[0094] In this implementation, since the side of the contact rod 30 abuts against the surface of the limit plate baffle 501, the maximum distance between the contact rod 30 and the support rod 20 is also the maximum distance between the support rod 20 and the limit plate baffle 501. In the process of adjusting the curvature of the bearing surface, the maximum distance between the contact rod 30 and the support rod 20 will change, that is, the maximum distance between the support rod 20 and the limit plate baffle 501 will also change. Two linear guide rails 101 are arranged, and the support rod 20 is slidably connected to the two linear guide rails 101, which facilitates the sliding of the support rod 20, thereby adjusting the maximum distance between the support rod 20 and the limit plate baffle 501.

[0095] The base 10 includes two opposite bottom plates 102 and two opposite support plates 103. The two ends of each support plate 103 are fixedly connected to the two bottom plates 102, and the two ends of the support rod 20 are connected to the two support plates 103. In this way, the two bottom plates 102 and the two opposite support plates 103 can be connected to form a shell (also called a frame) with a rectangular cross-section. Since the base 10 is a shell, the structure is stable and it is convenient to arrange structures such as the support rod 20, multiple contact rods 30, and the adjustment structure 40. It is worth noting that the base 10 can also be in other shapes as long as it can provide a stable support for the support rod 20.

[0096] like Figure 1 and Figure 8 As shown, one of the bottom plates 102 is a baffle 501, the other bottom plate 102 is opposite to the baffle 501, and two linear guide rails 101 are connected in parallel between the bottom plate 102 and the baffle 501. A rectangular through hole is provided in the support plate 103, and the linear guide rail 101 is located in the rectangular through hole of the support plate 103 and connected to the inner side wall of the support plate 103. That is, the support rod 20 is connected to the support plate 103 through the linear guide rail 101.

[0097] In other implementations, the support rod 20 may be directly fixedly connected to the support plate 103, that is, the support rod 20 cannot slide, and the support device may not be provided with an anti-rotation structure 50. When using the support device, the staff can directly fix the contact rod 30 by hand so that the contact rod 30 does not rotate.

[0098] like Figure 1 and Figure 8 As shown, two ends of the support plate 103 are connected to one side of the side edge of the bottom plate 102 , that is, the base 10 has an opening.

[0099] like Figure 1 and Figure 8 As shown, the base 10 further includes a side plate 104 , which connects the bottom plate 102 and the baffle 501 , and the side plate 104 and the linear guide rail 101 are located on two opposite sides of the bottom plate 102 .

[0100] In the embodiment of the present disclosure, the linear guide rail 101 is a fixed rod. Figure 2 Both ends of the support rod 20 have through holes 201 arranged along the length direction of the linear guide rail 101, and the two fixing rods pass through the two through holes 201 respectively.

[0101] In this implementation, through holes 201 are arranged at both ends of the support rod 20 , and the fixing rod passes through the through holes 201 , so that the support rod is sleeved on the fixing rod, thereby enabling the support rod 20 to slide along the linear guide rail 101 .

[0102] In the disclosed embodiment, the fixing rod is a cylindrical rod, and the inner diameter of the through hole 201 is larger than the inner diameter of the linear guide rail 101 , so as to facilitate the sliding of the support rod 20 .

[0103] In other implementations, the linear guide 101 is a slide groove, and both ends of the support rod 20 have sliders, and the sliders are slidably located in the slide groove to achieve the slidable connection between the support rod 20 and the linear guide 101.

[0104] In one implementation of the disclosed embodiment, the clamping member 502 is located on the linear guide rail 101 , and a force is applied to one end of the support rod 20 to press the contact rod 30 against the surface of the limit plate baffle 501 to prevent the contact rod 30 from rotating.

[0105] In one implementation of the embodiment of the present disclosure, the clamping member 502 is a second elastic element, the second elastic element is located on the linear guide rail 101, the second elastic element abuts against the support rod 20, and the second elastic element is in a state of providing pressure to the abutting support rod 20.

[0106] In this implementation, the second elastic element presses against one end of the support rod 20 to move the support rod 20 toward the baffle 501, so that the contact rod 30 presses against the surface of the baffle 501, preventing the contact rod 30 from rotating, which is more convenient.

[0107] In one implementation of the embodiment of the present disclosure, the second elastic element is a second compression spring in a compressed state, one end of the second compression spring abuts against one end of the support rod 20, and the other end of the second compression spring abuts against the bottom plate 102, which is more convenient.

[0108] In other implementations, the second elastic element may also be a second elastic sheet in a compressed state, and the second elastic sheet may also provide pressure to the hinge ring 401 .

[0109] In one implementation of the embodiment of the present disclosure, the side surface of one contact rod 30 abuts against the surface of the limit plate baffle 501. In other implementations, the side surfaces of two contact rods 30 may abut against the surface of the limit plate baffle 501.

[0110] Fig. 9Schematic diagram of a baffle provided by an embodiment of the present disclosure. Fig. 9 The surface of the baffle 501 opposite to the bottom plate 102 has a strip groove 511 , the extension direction of the strip groove 511 is parallel to the length direction of the contact rod 30 , and one contact rod 30 is located in the strip groove 511 .

[0111] In this implementation, a strip groove 511 is arranged on the surface of the baffle 501 , and the contact rod 30 is located in the strip groove 511 , which can enhance the limiting effect and prevent the contact rod 30 from rotating.

[0112] like Fig. 9 As shown, the strip groove 511 is arranged close to one side of the baffle 501. When the entire supporting device is manufactured, the strip groove 511 is opposite to the contact rod 30, ensuring that the contact rod 30 can be located in the strip groove 511, thereby achieving an enhanced limiting effect.

[0113] In an implementation of the embodiment of the present disclosure, the cross section of the strip-shaped groove 511 is semicircular, and the radius of the semicircle is equal to the radius of the contact rod 30 .

[0114] Fig.10 yes Figure 2 See also Figure 2 and Fig.10 , multiple contact rods 30 are arranged in a circular array with equal spacing around the support rod 20.

[0115] In this implementation, multiple contact rods 30 are arranged in a circular array with equal spacing around the support rod 20 to ensure the flatness of the formed bearing surface. At the same time, the bearing surface formed by the multiple contact rods 30 is a cylindrical side surface. During the process of adjusting the curvature, if the contact rods 30 rotate, it can always ensure that the flexible plate-like structure 200 can fit on the bearing surface, which is more convenient.

[0116] In other implementations, the contact rods 30 may be arranged in a fan-shaped manner with the center line of the support rod 20 as the center line and at even intervals.

[0117] like Fig.10 As shown, the side faces of the plurality of contact rods 30 form a polygonal shape, such as Fig.10 As shown by the middle dotted line, the greater the number of contact rods 30 , the closer the shape formed by the side surfaces of the contact rods 30 is to a circle.

[0118] Fig.11 Schematic diagram of a flexible plate structure provided by an embodiment of the present disclosure being attached to a bearing surface. Fig.11 The flexible plate-like structure 200 is attached to the bearing surface A, so that the flexible plate-like structure 200 has an arc-shaped curved surface.

[0119] In the embodiment of the present disclosure, the number of the contact rods 30 is between 15 and 30. By limiting the number of the contact rods 30, the bearing surface formed by the contact rods 30 is close to an arc, so that the bending of the flexible plate-like structure 200 on the bearing surface is close to an arc, thereby increasing the accuracy of subsequent detection results.

[0120] By way of example, the number of contact rods 30 is twenty.

[0121] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
