The retaining member 11 can be used to limit the first device so that the first device can be stably placed on the first bracket 10. The width dimension of the first bracket 10 is greater than the width dimension of the first support frame 20, and the area enclosed by the first bracket 10 is the first hollow portion 10a, and the first hollow portion 10a can accommodate the first support frame 20. When the first support frame 20 is in the storage state, the first support frame 20 is embedded in the side of the first hollow portion 10a away from the retaining member 11. The connection point between the first bracket 10 and the first support frame 20 is the rotating end 21 of the first support frame 20.

In this way, the folding bracket 100 can be switched from the storage state to the first support state, thereby meeting the support limit requirements of the first device.

[0038] In the present embodiment, when the user needs to switch the folding bracket 100 from the storage state to the first supporting state, the user rotates the first supporting frame 20 and fixes the rotated first supporting frame 20 to the second supporting frame 30 and the second bracket 40.

When the second bracket 40 is in the storage state, the second bracket 40 is partially embedded in the third hollow portion 30a, and the opening direction of the second bracket 40 is opposite to the opening direction of the first support frame 20. The connection between the second bracket 40 and the second support frame 30 is the rotating end 41 of the second bracket 40, and the rotating end 41 of the second bracket 40 is arranged on the side away from the blocking member 11, and the free end 42 of the second bracket 40 is arranged on the side close to the rotating end 31 of the second support frame 30. The free end 42 of the second bracket 40 can rotate along the rotating section of the second bracket 40, so that the second bracket 40 can rotate from the third hollow portion 30a to the unfolded state.

[0043] In this embodiment, when the user needs to switch the folding bracket 100 from the storage state to the second support state, the user first rotates the rotating end of the second support frame 30 to rotate the free end 32 of the second support frame 30 from the second hollow portion 20a to the unfolded state, and then rotates the rotating end 41 of the second bracket 40 to rotate the free end 42 of the second bracket 40 from the third hollow portion 30a to the unfolded state, and the second support frame 30 is set at an angle relative to the first support frame 20, and the second bracket 40 is set at an angle with the second support frame 30. So that the second device can be placed in the second bracket 40.

[0045] Specifically, the second bracket 40 is provided with a protrusion 45, and the protrusion 45 includes but is not limited to being made of metal materials, such as aluminum alloy, stainless steel and magnesium alloy, and has high strength and stability. The protrusion 45 is extended in the direction of the fourth hollow portion 40a, and the protrusion 45 is located on one side of the free end 42 of the second bracket 40. The protrusion 45 and the second bracket 40 are an integrally formed structure, and a pair of the support feet 50 are relatively arranged on both sides of the protrusion 45, and a pair of the support feet 50 are rotatably connected to the second bracket 40 near the free end 42 of the second bracket 40; the connection between the support feet 50 and the second bracket 40 is the rotating end of the support feet 50, and when the support feet 50 is in the storage state, the rotating end of the support feet 50 is located on the side close to the stopper 11, and the free end of the support feet 50 is located on the side of the rotating end of the support feet 50 away from the stopper 11. The support legs 50 rotate in a circle with the rotating end of the support legs 50, and the support legs 50 and the second bracket 40 are interference fit, so that the support legs 50 can be deployed at any position on the rotation path. A pair of the support legs 50 is used to support the second device to prevent the second device from falling from the second bracket 40. Optionally, the pair of the support legs 50 can also be rotatably connected to the protrusion 45.

[0046] In this embodiment, when the folding bracket 100 rotates from the storage state to the second supporting state, the user first rotates the rotating end of the second supporting frame 30 to rotate the free end 32 of the second supporting frame 30 from the second hollow portion 20a to the unfolded state; the user then rotates the rotating end 41 of the second bracket 40 to rotate the free end 42 of the second bracket 40 from the third hollow portion 30a to the unfolded state, the second supporting frame 30 is set at an angle relative to the first supporting frame 20, and the second bracket 40 is set at an angle with the second supporting frame 30, and finally the support foot 50 is rotated from the fourth hollow portion 40a to the unfolded state, so as to realize the rotation of the folding bracket 100 from the storage state to the second supporting state. So that the pair of support feet 50 can rotate synchronously and stop at the same angle, so as to ensure the stability and flatness of the pair of support feet 50 when supporting the second device.

[0047] See also Figure 8 and Fig. 9 In one embodiment, the second support frame 30 further includes a retaining plate 35, and the retaining plate 35 is disposed in the fourth hollow portion 40a.

Preferably, the positioning plate 35 is fixed to one side of the free end 32 of the second support frame 30, and the positioning plate 35 is extended in the direction of the fourth hollow portion 40a. The positioning plate 35 is used to abut the first support frame 20 so that the first support frame 20 can be restricted by the positioning plate 35. The width of the positioning plate 35 is smaller than the width of the second bracket 40 so that the positioning plate 35 can be embedded in the fourth hollow portion 40a. In another embodiment, the retaining plate 35 and the second support frame 30 may be an integrally formed structure, so that the retaining plate 35 and the second support frame 30 have a higher connection strength.

[0049] In this embodiment, by providing the locking plate 35 on the second support frame 30, when the folding bracket 100 switches from the storage state to the first support state, the first support frame 20 can be locked on the locking plate 35. At the same time, the locking plate 35 and the second support frame 30 are integrally provided, thereby improving the support strength of the second support frame 30.

[0050] See also Figure 8 and Fig. 9 In one embodiment, the second bracket 40 is also rotatably connected to the locking plate 35, and the locking plate 35 rotates synchronously and coplanarly with the rotation of the second support frame 30. When the second support frame 30 and the second bracket 40 are both rotated to the unfolded state, the locking plate 35 is in the unfolded state.

[0051] Specifically, when the folding bracket 100 is in the storage state, the area enclosed by the positioning plate 35 and the second support frame 30 is used to embed the second bracket 40, and the positioning plate 35 and the second support frame 30 are arranged coplanar. The rotating end 41 of the second bracket 40 is also rotatably connected to the side of the positioning plate 35 away from the stopper 11, and the second bracket 40 rotates relative to the second support frame 30 and the positioning plate 35.

The user then rotates the rotating end 41 of the second bracket 40 to rotate the free end 42 of the second bracket 40 from the third hollow portion 30a to the expanded state, the second support frame 30 is set at an angle relative to the first support frame 20, and the second bracket 40 is set at an angle with the second support frame 30, and finally the support foot 50 is rotated from the fourth hollow portion 40a to the expanded state, so that the folding bracket 100 is rotated from the storage state to the second support state, so that the second device can be placed on the folding bracket 100.

[0053] See also Figures 7 to 9 In one embodiment, the first support frame 20 has a locking member 25, and the locking member 25 is protruded on the first support frame 20. The first hollow portion 10a has a receiving portion 10b. When the first support frame 20 is in a stored state, the locking member 25 is embedded in the receiving portion 10b; wherein, the locking member 25 is used in conjunction with the locking plate 35.

[0054] Specifically, the positioning member 25 includes but is not limited to being made of metal materials, such as aluminum alloy, stainless steel and magnesium alloy, and has high strength and stability.

When the folding bracket 100 is in the storage state, the positioning member 25 is arranged on one side of the free end 22 of the first support frame 20, and the positioning member 25 is embedded in the receiving portion 10b. The positioning member 25 can be an integrally formed structure with the free end 22 of the first support frame 20, and has a high connection strength. Of course, in other embodiments, the positioning member 25 can also be fixedly connected to the free end 22 of the first support frame 20 by screw connection, station connection or clamping.

[0055] Please also read Figure 2 and Figure 7 When the folding bracket 100 rotates from the storage state to the first supporting state, the first supporting frame 20 rotates to the unfolded state, the first bracket 10 rises relative to the second supporting frame 30, and the locking member 25 is locked on the locking plate 35, so that the first supporting frame 20 can be fixed on the locking plate 35, so that the folding bracket 100 can be maintained in the first supporting state and prevent the first supporting frame 20 from sliding off the locking plate 35.

[0056] See also Figures 10 to 12 In one embodiment, the locking plate 35 is provided with a plurality of locking grooves 35a, and the plurality of locking grooves 35a are arranged in sequence at intervals.

Each positioning groove 35a has the same size, and the positioning member 25 can be engaged with each positioning groove 35a.

[0058] When the folding bracket 100 switches from the storage state to the first support state, the first support frame 20 rotates to the unfolded state, and the first bracket 10 rises as the first support frame 20 rotates. The locking member 25 of the first support frame 20 can be locked in any of the locking grooves 35a to prevent the first support frame 20 from sliding off the locking plate 35. When the locking member 25 is locked with each of the locking grooves 35a, the heights of the first bracket 10 are different. When the locking member 25 is locked with the locking groove 35a near the free end of the second support frame 30, the angle formed by the first bracket 10 and the second support frame 30 is a first angle, and the vertical height between the side of the first bracket 10 away from the stopper 11 and the second support frame 30 is a first height. When the locking member 25 is locked with each of the locking grooves 35a, the heights of the first bracket 10 are different. When the locking member 25 is locked with the locking groove 35a near the rotating end of the second support frame 30, the angle formed by the first bracket 10 and the second support frame 30 is the second angle, and the vertical height between the side of the first bracket 10 away from the blocking member 11 and the second support frame 30 is the second height. The first angle is smaller than the second angle, and the first height is lower than the second height.

[0059] It can be understood that the engagement of the positioning groove 35a with the positioning member 25 from the side away from the retaining member 11 to the side close to the retaining member 11 can make the angle between the first bracket 10 and the second support frame 30 larger and larger, and the vertical height of the first bracket 10 relative to the second support frame 30 also becomes higher and higher. The user can adjust the engagement relationship between the positioning member 25 and the positioning groove 35a according to the actual required height and angle, so that the folding bracket 100 has higher flexibility. In this embodiment, six identical positioning grooves 35a are provided, corresponding to the folding bracket 100 in the first supporting state. Of course, in other embodiments, the number of the positioning grooves 35a can be increased or decreased according to actual needs, which all belong to the protection scope of this embodiment.

[0061] Specifically, the first protective member 61 and the second protective member 62 include, but are not limited to, natural rubber, gelatin, nitrile rubber, EVA rubber and other materials, and have good buffering, anti-skid, shockproof and other properties. The first bracket 10 has a first surface 19, which is a side of the first device abutting, and a plurality of first protective members 61 are arranged on the first surface 19. The first protective pad is in the shape of a long rectangular strip. Optionally, the first protective member 61 is arranged on the side of the first bracket 10, and the first protective member 61 is fixed on the first surface 19 by bonding or clamping. Similarly, the blocking member 11 is also provided with a first protective member 61. The second bracket 40 has a second surface 29, which is a side of the second device abutting, and a plurality of second protective members 62 are arranged on the second surface 29.
