[0034] Specifically, the first support plate 10 and the second support plate 20 are both rectangular block-shaped structures. The connection methods of the first support plate 10 and the second support plate 20 include, but are not limited to, snap-fitting, screwing, bonding, welding, or an integrally formed structure. Preferably, the first support plate 10 and the second support plate 20 are integrally formed, providing strong connection strength. The width of the first support plate 10 is smaller than the width of the second support plate 20. The first receiving portion 10a is located on the side of the first support plate 10 near the second support plate 20. The first receiving portion 10a is in the shape of a rectangular groove and completely penetrates the first support plate 10, allowing the third support frame 50 to rotate to the second support state S2.

Optionally, the thickness of the first support plate 10 , the thickness of the first support frame 30 , and the thickness of the second support frame 40 may be the same, so as to facilitate storage of the folding bracket 100 .

[0035] See also Figure 2When the folding bracket 100 rotates to the first supporting state S1, the first supporting frame 30 and the second supporting frame 40 rotate to the first supporting state S1, the third supporting frame 50 is in the storage state S, the first supporting plate 10 and the second supporting plate 20 serve as fixed bases, and the first plane 12a of the first supporting plate 10 is placed on any plane and fits in with the plane as support. The rotating end of the first supporting frame 30 rotates and drives the free end of the first supporting frame 30 to rotate, and the first supporting frame 30 is set at an angle relative to the first supporting plate 10; the rotating end of the second supporting frame 40 rotates and drives the free end of the second supporting frame 40 to rotate, and the second supporting frame 40 is set at an angle relative to the first supporting frame 30. At this time, the folding bracket 100 is used to place a first device (not shown), and the first device includes but is not limited to larger electronic devices such as tablet computers and laptop computers.

[0036] See also Figure 3 When the folding bracket 100 rotates to the second supporting state S2, the first supporting frame 30, the second supporting frame 40 and the third supporting frame 50 rotate to the second supporting state S2, and the free end of the first supporting frame 30 and the end of the second supporting plate 20 away from the first supporting plate 10 serve as a fixed base support. The rotating end of the first supporting frame 30 rotates and drives the free end of the first supporting frame 30 to rotate, and the first supporting frame 30 is set at an angle relative to the first supporting plate 10; the rotating end of the second supporting frame 40 rotates and drives the free end of the second supporting frame 40 to rotate, and the second supporting frame 40 is set at an angle relative to the first supporting frame 30; the rotating end of the third supporting frame 50 rotates and drives the free end of the third supporting frame 50 to rotate, and the third supporting frame 50 is set at an angle relative to the first supporting plate 10. At this time, the folding bracket 100 is used to place a second device (not shown), and the second device includes but is not limited to handheld electronic devices such as smartphones and mini tablets.

[0037] In the present application, by arranging the first support plate 10, the second support plate 20, the first support frame 30, the second support frame 40 and the third support frame 50 in the folding bracket 100 and rotating them together, the folding bracket 100 can adapt to the placement function of various electronic products, and the folding bracket 100 can switch between the storage state S, the first support state S1 and the second support state S2.

[0038] In one embodiment, the second support plate 20 includes a first support plate 21 and a limit platform 22. The limit platform 22 is fixedly connected to the first support plate 21. The limit platform 22 is arranged on the side of the second support plate 20 away from the first support plate 10. The limit platform 22 is used to limit the first device when the folding bracket 100 is in the first supporting state S1.

[0039] Specifically, the first support plate 21 is in the shape of a rectangular block, and the limiting platform 22 is in the shape of a rectangular strip. The limiting platform 22 is arranged on the side of the first support plate 21 away from the first supporting plate 10; the thickness of the limiting platform 22 is greater than the thickness of the first support plate 21 to form a height offset difference for the placement of the first electronic device. Optionally, the thickness of the limiting platform 22 can be equal to the thickness of the first support frame 30 or the thickness of the limiting platform 22 can be less than the thickness of the first support frame 30 to facilitate the storage of the folding bracket 100. The first support plate 21 and the limiting platform 22 can be an integrally formed structure or the first support plate 21 and the limiting platform 22 can also be a detachable structure; preferably, the first support plate 21 and the limiting platform 22 are an integrally formed structure with good connection strength.

[0040] In this embodiment, by providing the limit platform 22 on the second support plate 20 and having a thickness difference with the first support plate 21 , the first device can be placed on the first support plate 21 to prevent the first device from sliding off the second support plate 20 .

[0041] See also Figure 1 and Figure 4 In one embodiment, the first support frame 30 has a second receiving portion 30a. When the first support frame 30 and the second support frame 40 are in the storage state S, the second support frame 40 is embedded in the second receiving portion 30a; the rotating end of the first support frame 30 is located on the side close to the second support plate 20, and the free end of the first support frame 30 is located on the side away from the second support plate 20.

[0042] Specifically, the width of the first support frame 30 is greater than the width of the second support frame 40. The area enclosed by the first support frame 30 and the first support plate 10 is the second receiving portion 30a, and the second receiving portion 30a can receive the second support frame 40. When the folding bracket 100 is in the storage state S, the second support frame 40 is embedded in the second receiving portion 30a, and the second receiving portion 30a is located on the side of the first support plate 10 facing away from the second support plate 20. The second support frame 40 and the first support frame 30 are clearance-fitted, and there is a first gap (not shown) between the second support frame 40 and the first support frame 30. The first gap is used to avoid frictional contact between the second support frame 40 and the first support frame 30, so that when the folding bracket 100 switches from the storage state S to the first support state S1 or to the second support state S2, the second support frame 40 can smoothly rotate and slide out of the second receiving portion 30a. Similarly, the second support frame 40 and the first support plate 10 are also clearance-matched, and there is a second gap (not shown) between the second support frame 40 and the first support plate 10. The second gap is used to avoid frictional contact between the second support frame 40 and the first support plate 10, so that when the folding bracket 100 switches from the storage state S to the first support state S1 or switches to the second support state S2, the second support frame 40 can smoothly rotate and slide out from the second receiving portion 30a.

[0043] In this embodiment, by providing a second receiving portion 30a in the first support frame 30, the second support frame 40 can be received in the second receiving portion 30a, and by providing the second support frame 40 with a clearance-fit structure with the first pallet 10 and the first support frame 30 respectively, the second support frame 40 can smoothly rotate and slide out of the second receiving portion 30a when rotating, thereby improving the convenience of use of the product.

[0044] See also Figure 5 In one embodiment, the first support frame 30 has a first supporting side 30b, and the second support plate 20 has a second supporting side 20b. When the folding bracket 100 is in the second supporting state S2, the first support frame 30 and the second support plate 20 are set at an angle, and the first supporting side 30b and the second supporting side 20b are in contact with a plane.

[0045] Specifically, the first supporting side 30b is provided at the free end of the first support frame 30, and the first supporting side 30b is located on one side of the second plane 12b; the second supporting side 20b is provided at the free end of the second supporting plate 20, and the second supporting side 20b is located on the side facing away from the limiting platform 22. When the folding bracket 100 is in the stowed state S, the first supporting side 30b and the second supporting side 20b are parallel to each other, and the first support frame 30 and the second supporting plate 20 are parallel to and abut against the plane; when the folding bracket 100 is in the second supporting state S2, the first support frame 30 and the second supporting plate 20 are rotated relative to each other to form an angle, and the second supporting plate 20 rotates relative to the first support frame 30, and the height of the end of the second supporting plate 20 facing away from the second supporting side 20b gradually increases with respect to the plane, and the height of the end of the first support frame 30 facing away from the first supporting side 30b also gradually increases with respect to the plane. As the angle between the first support frame 30 and the second support plate 20 gradually decreases, the rotating end of the first support frame 30 will gradually rise away from the plane, so that the user can achieve a higher support height when using the folding stand 100 to place a second device. At this time, the second support plate 20 forms a first angle with the plane, the first support frame 30 forms a second angle with the plane, and the first support side 30b and the second support side 20b abut against the plane. The first support side 30b and the second support side 20b support the folding stand 100 to ensure that it remains in the second support state S2.

[0046] In this embodiment, the first supporting side 30b and the second supporting side 20b serve as fulcrums, so that the overall structure of the folding bracket 100 remains stable after switching from the storage state S or the first supporting state S1 to the second supporting state S2.

[0047] See also Figure 1 and Figure 6 In one embodiment, the third support frame 50 includes a rotating portion 53 and a second support plate 52, the rotating portion 53 is provided at one end of the second support plate 52, and the rotating portion 53 is connected to the first support plate 10; the third support frame 50 is also provided with a support foot 51, and the support foot 51 is provided at one end of the second support plate 52 away from the rotating portion 53, and the support foot 51 is used to limit the second device when the folding bracket 100 is in the second supporting state S2.

[0048] Specifically, the third support frame 50 and the first support plate 10 are clearance-fitted, and the third support frame 50 and the first support plate 10 have a third gap (not shown), and the third gap is used to avoid frictional contact between the third support frame 50 and the first support plate 10, so that when the folding bracket 100 switches from the storage state S to the second support state S2, the third support frame 50 can smoothly rotate and slide out of the first receiving portion 10a.

[0049] The second support plate 52 is U-shaped. When the folding stand 100 is in the stowed state S, the opening of the second support plate 52 faces away from the end of the second support plate 20. The rotating portion 53 is located on the side of the second support plate 52 near the second support plate 20 and is in the shape of a rectangular block. The support foot 51 is located at the free end of the third support frame 50 and includes, but is not limited to, a rectangular block-shaped structure. The thickness of the second support plate 52 is smaller than that of the support foot 51 to create a height difference for the placement of the second electronic device. Optionally, the thickness of the support foot 51 can be equal to or smaller than that of the first support frame 30 to facilitate the stowage of the folding stand 100. Optionally, the thickness of the rotating portion 53 can be equal to or smaller than that of the first support frame 30 to facilitate the stowage of the folding stand 100. The second support plate 52, the rotating part 53 and the support foot 51 can be an integrally formed structure or a detachable structure; preferably, the second support plate 52, the rotating part 53 and the support foot 51 are an integrally formed structure, so that the third support frame 50 is easy to process and produce, and has good connection strength.

[0050] In this embodiment, by arranging the rotating part 53 and the support foot 51 on the third support frame 50, the rotating part 53 can drive the third support frame 50 to rotate and slide out from the first receiving portion 10a. When the folding bracket 100 is in the second supporting state S2, the second support plate 52 is used to place the second device, and the support foot 51 can limit the second device from sliding out of the second support plate 52, thereby improving the safety of the folding bracket 100.

[0051] See also Figure 7 、 Figure 8 and Figure 9In one embodiment, the first support plate 10 is provided with a first limiting member 11, the first limiting member 11 is protruded from the first receiving portion 10a, the first support plate 10 has a first plane 12a and a second plane 12b arranged opposite to each other, and the first limiting member 11 is arranged on a side close to the first plane 12a; when the folding bracket 100 is in the storage state S, the first limiting member 11 limits the third support frame 50 from flipping toward the side of the first plane 12a; when the folding bracket 100 is in the second supporting state S2, the first limiting member 11 limits the third support frame 50 from settling toward the side of the second plane 12b.

[0052] Specifically, the first limiting member 11 includes but is not limited to a rectangular block, and the first limiting member 11 and the first support plate 10 include but are not limited to an integrally formed structure, or the first limiting member 11 can be a detachable structure with the first support plate 10, such as a fixing method such as snap connection or bonding. Preferably, the first limiting member 11 and the first support plate 10 are an integrally formed structure, so that the first limiting member 11 and the first support plate 10 have good connection strength. One side of the extension direction of the limiting platform 22 is the first plane 12a, and the side facing away from the extension direction of the limiting platform 22 is the second plane 12b. The first limiting member 11 is extended along the second support plate 20 toward the direction of the first support plate 10.

[0053] See also Figure 8 and Figure 10The third support frame 50 is provided with a first avoidance groove 53a, which is recessed on the side of the rotating portion 53 facing away from the support leg 51. The first avoidance groove 53a partially penetrates the rotating portion 53 along the direction from the first plane 12a to the second plane 12b. The first avoidance groove 53a is used to prevent the first limiting member 11 from frictionally contacting the rotating portion 53, so that when the folding bracket 100 switches from the storage state S to the second support state S2, the third support frame 50 can smoothly rotate and slide out of the first receiving portion 10a. The rotating portion 53 has a first abutting surface 53b, which is provided on the side of the rotating portion 53 facing away from the support leg 51; the first limiting member 11 has a second abutting surface 11a, which is located on the side of the first limiting member 11 facing away from the first plane 12a. When the folding bracket 100 is in the storage state S, since the first limiting member 11 is provided on the side close to the first plane 12a, the first limiting member 11 limits the rotation of the rotating portion 53 toward the extension direction of the support leg 51. The thickness of the first limiting member 11 is smaller than the thickness of the first avoidance groove 53a. When the folding bracket 100 is in the second supporting state S2, the third support frame 50 rotates and extends toward the side facing away from the limiting platform 22; at this time, the third support frame 50 rotates to the first position, and the first abutting surface 53b and the second abutting surface 11a abut against each other to prevent the third support frame 50 from sinking toward the side of the second plane 12b, so that the second support plate 52 can have a stable support surface to prevent the second device from sliding out.

[0054] In this embodiment, when the folding stand 100 switches from the first supporting state S1 to the second supporting state S2, the first supporting frame 30 and the second supporting plate 20 are first flipped toward the plane, and the folding stand 100 is upright and fixed using the first supporting side 30b and the second supporting side 20b as support. Then, the free end of the third supporting frame 50 is rotated out of the first receiving portion 10a from one side of the second plane 12b, and the first limiting member 11 abuts against the rotating portion 53, so that the folding stand 100 remains in the second supporting state S2. The above operation is simple and convenient. The user can switch the folding stand 100 from the first supporting state S1 to the second supporting state S2 by simply flipping the stand, which provides high flexibility.

[0055] In this embodiment, by providing the first limiting member 11 on the first support plate 10 and opening a first avoidance groove 53a on one side of the rotating part 53 of the third support frame 50, the first limiting member 11 can limit the rotation range of the third support frame 50, thereby enabling the folding bracket 100 to switch between the storage state S, the first support state S1 and the second support state S2.

[0056] See Figure 8 and Figure 9 In one embodiment, the first support plate 10 is provided with a plurality of latching grooves 13a, and the latching grooves 13a are arranged at one end of the first support plate 10 away from the second support plate 20. When the folding bracket 100 is in the first supporting state S1 or the second supporting state S2, the free end of the second support frame 40 is cooperated and connected with the latching grooves 13a.

[0057] Specifically, a plurality of latching grooves 13a are recessed on the first plane 12a of the first support plate 10. The plurality of latching grooves 13a are arranged in sequence and spaced apart. The plurality of latching grooves 13a extend through the width direction of the first support plate 10, and the sizes of the latching grooves 13a are the same. The second support frame 40 includes a first latching portion 41, which is arranged on one side of the free end of the second support frame 40. The first latching portion 41 is also provided with a second avoidance groove 41a, which partially passes through the first latching portion 41 along the second plane 12b toward the first plane 12a. When the folding bracket 100 is in the first supporting state S1, the first latching portion 41 can be latched in the latching groove 13a to achieve the supporting effect of the second support frame 40 on the first support frame 30.

[0058] Please also refer to Figure 2 、 Figure 8 、 Figure 9 and Figure 11When the first clamping portion 41 is clamped with each of the clamping slots 13a, the height and inclination of the first support frame 30 are different. When the first clamping portion 41 is clamped with the clamping slot 13a on the side close to the free end of the first support plate 10, the angle formed by the first support frame 30 and the second support frame 40 is a first angle (not shown), and the vertical height of the free end of the first support frame 30 relative to the ground is a first height (not shown). When the first clamping portion 41 is clamped with the clamping slot 13a on the side close to the rotating end of the first support plate 10, the angle formed by the first support frame 30 and the second support frame 40 is a second angle (not shown), and the vertical height of the free end of the first support frame 30 relative to the ground is a second height (not shown). The first angle is greater than the second angle, and the first height is higher than the second height. The user can adjust the matching relationship between the first clamping portion 41 and the clamping slot 13a according to the actual height and angle required, so that the folding bracket 100 has high flexibility. In this embodiment, six identical latching slots 13a are provided, corresponding to six first support states S1 of the folding bracket 100. Of course, in other embodiments, the number of the latching slots 13a can be increased or decreased according to actual needs, which falls within the scope of protection of this embodiment.

[0059] In this embodiment, a plurality of the locking grooves 13a are provided on the first support plate 10, and the first clamping portion 41 is provided on the second support frame 40. The first clamping portion 41 is engaged with the locking groove 13a to realize the rotation of the folding bracket 100 from the storage state S to the first support state S1. The plurality of the locking grooves 13a can also adjust the support angle and height of the folding bracket 100, so that the user can adjust the folding bracket 100 according to actual needs.

[0060] See also Figure 12 、 Figure 13 、 Figure 14 and Figure 15 In one embodiment, the first support plate 10 is provided with a second limiting member 15, the second limiting member 15 is protruded from the first receiving portion 10a, the first support plate 10 has a first plane 12a and a second plane 12b arranged opposite to each other, and the second limiting member 15 is arranged on a side close to the second plane 12b; when the folding bracket 100 is in the storage state S, the second limiting member 15 limits the third support frame 50 from flipping toward the side of the second plane 12b; when the folding bracket 100 is in the second supporting state S2, the second limiting member 15 limits the third support frame 50 from settling toward the side of the first plane 12a.

[0061] Specifically, the second limiting member 15 includes but is not limited to a rectangular block shape, and the second limiting member 15 and the first support plate 10 include but are not limited to an integrally formed structure, or the second limiting member 15 can be a detachable structure with the first support plate 10, such as a fixing method such as snap connection or bonding. Preferably, the second limiting member 15 and the first support plate 10 are an integrally formed structure, so that the second limiting member 15 and the first support plate 10 have good connection strength. One side of the extension direction of the limiting platform 22 is the first plane 12a, and the side facing away from the extension direction of the limiting platform 22 is the second plane 12b. The second limiting member 15 is extended along the second support plate 20 toward the direction of the first support plate 10.

[0062] See also Figure 13 and Figure 15 The third support frame 50 is provided with a first avoidance groove 53a, which is recessed on the side of the rotating portion 53 facing away from the support leg 51. The first avoidance groove 53a partially penetrates the rotating portion 53 along the direction from the first plane 12a to the second plane 12b. The first avoidance groove 53a is used to prevent the second limiting member 15 from frictionally contacting the rotating portion 53, so that when the folding bracket 100 switches from the storage state S to the second support state S2, the third support frame 50 can smoothly rotate and slide out of the first receiving portion 10a. The rotating portion 53 has a first abutting surface 53b, which is provided on the side of the rotating portion 53 facing away from the support leg 51; the second limiting member 15 has a third abutting surface 15a, which is located on the side of the second limiting member 15 facing away from the second plane 12b. When the folding bracket 100 is in the storage state S, since the second limiting member 15 is provided on the side close to the second plane 12b, the second limiting member 15 limits the rotation of the rotating portion 53 toward the extension direction of the support leg 51. The thickness of the second limiting member 15 is smaller than the thickness of the first avoidance groove 53a. When the folding bracket 100 is in the second supporting state S2, the third support frame 50 rotates and extends toward the side facing away from the limiting platform 22; at this time, the third support frame 50 rotates to the second position, and the first abutting surface 53b and the third abutting surface 15a abut against each other to prevent the third support frame 50 from sinking toward the side of the second plane 12b, so that the second support plate 52 can have a stable support surface to prevent the second device from sliding out.

[0063] In this embodiment, when the folding bracket 100 switches from the first supporting state S1 to the second supporting state S2, the first supporting frame 30 and the second supporting frame 40 located on one side of the first plane 12a are first rotated to the storage state S, and then the first supporting frame 30 is rotated relative to the first support plate 10 to the side of the second plane 12b, and then the second supporting frame 40 is rotated toward the side of the first support plate 10 so that the second supporting frame 40 abuts against the first support plate 10, and the first supporting frame 30 and the second support plate 20 are set at an angle, and the first supporting side 30b and the second supporting side 20b serve as supports to stand up and fix the folding bracket 100, and finally the free end of the third supporting frame 50 is rotated and flipped out from the first receiving portion 10a from the side of the first plane 12a, and the second limiting member 15 abuts against the rotating portion 53, so that the folding bracket 100 remains in the second supporting state S2. The above operation is simple and convenient. The user can switch the folding bracket 100 from the first supporting state S1 to the second supporting state S2 by simple operations such as flipping, which has high flexibility.

[0064] In this embodiment, by providing the second limit member 15 on the first support plate 10 and opening a first avoidance groove 53a on one side of the rotating part 53 of the third support frame 50, the second limit member 15 can limit the rotation range of the third support frame 50, thereby enabling the folding bracket 100 to switch between the storage state S, the first support state S1 and the second support state S2.

[0065] See also Figure 12 and Figure 13 In one embodiment, the first support plate 10 is provided with a plurality of positioning holes 14a, and the plurality of positioning holes 14a are arranged in sequence and spaced apart. The second support frame 40 is provided with a protrusion, and the protrusion can cooperate with each of the positioning holes 14a to engage and adjust the support angle of the second support frame 40 and the first support frame 30.

[0066] Specifically, the plurality of positioning holes 14a extend along the first plane 12a to the second plane 12b, and the plurality of positioning holes 14a are arranged in sequence at intervals, and the size of each positioning hole 14a is the same. The positioning holes 14a extend along the width direction of the first support plate 10, and the positioning holes 14a include but are not limited to circular arc grooves, rectangular grooves and other structures. Preferably, the positioning holes 14a are long arc grooves. The second support frame 40 includes a second clamping portion 42, and the second clamping portion 42 is protruding from the free end of the second support frame 40. The second clamping portion 42 extends along the second support plate 20 toward the first support plate 10. The thickness of the second clamping portion 42 is smaller than the thickness of the second support frame 40, so that the second clamping portion 42 can be easily clamped into the positioning hole 14a. When the folding bracket 100 is in the first supporting state S1, the second clamping portion 42 is inserted into the clamping hole 14a from one side of the first plane 12a of the first supporting plate 10, so that the second supporting frame 40 supports the first supporting frame 30. When the folding bracket 100 is in the second supporting state S2, the second clamping portion 42 is inserted into the clamping hole 14a from one side of the second plane 12b of the first supporting plate 10, so that the second supporting frame 40 supports the first supporting plate 10.

[0067] When the second engaging portion 42 engages with each of the engaging holes 14a, the first support frame 30 is raised to a different height and inclination. When the second engaging portion 42 engages with the engaging hole 14a near the free end of the first support plate 10, the angle formed by the first support frame 30 and the second support frame 40 is a first angle, and the vertical height of the free end of the first support frame 30 relative to the ground is a first height. When the second engaging portion 42 engages with the engaging hole 14a near the rotating end of the first support plate 10, the angle formed by the first support frame 30 and the second support frame 40 is a second angle, and the vertical height of the free end of the first support frame 30 relative to the ground is a second height. The first angle is greater than the second angle, and the first height is greater than the second height. The user can adjust the mating relationship between the second engaging portion 42 and the engaging hole 14a according to the desired height and angle, thereby providing the folding stand 100 with greater flexibility. In this embodiment, six identical engaging holes 14a are provided, corresponding to six first support states S1 of the folding stand 100. Of course, in other embodiments, the number of the positioning holes 14a may be increased or decreased according to actual needs, which all fall within the protection scope of this embodiment.

[0068] In this embodiment, a plurality of the locking holes 14a are provided on the first support plate 10, and a second clamping portion 42 is provided on the second support frame 40. The second clamping portion 42 is engaged with the locking holes 14a to realize the rotation of the folding bracket 100 from the storage state S to the first support state S1. The plurality of the locking holes 14a can also adjust the support angle and height of the folding bracket 100, so that the user can adjust it at will according to actual needs.

[0069] See also Figure 16 and Figure 17 In a real-time manner, the second support plate 20 is provided with a first hollow portion 26a, and the first hollow portion 26a is used to reserve a first avoidance space for the first device. The third support frame 50 is provided with a second hollow portion 16a, and the second hollow portion 16a is used to reserve a second avoidance space for the second device.

[0070] Specifically, the first hollow portion 26a partially penetrates the first support plate 21 in the direction from the first plane 12a to the second plane 12b. The first hollow portion 26a includes but is not limited to a rectangular groove, a circular groove, a polygonal groove, and other structures. When the folding stand 100 is in the first support state S1, the first device abuts against the first support plate 21, and the first avoidance space (not shown) can be used for the first electronic device to perform wiring operations such as charging and data transmission. The second hollow portion 16a penetrates the second support plate 52 in the direction from the first plane 12a to the second plane 12b. The second hollow portion 16a includes but is not limited to a U-shaped groove and other structures. When the folding stand 100 is in the second support state S2, the second device abuts against the second support plate 52. The second avoidance space (not shown) can be used for the second electronic device to perform wiring operations such as charging and data transmission. When the second device is in the wiring state, the second hollow portion 16a can avoid the wiring of the second device and place it directly on the third support frame 50, avoiding the need to remove the charging cable and other tasks, thereby improving user convenience.
