[0036] See also Figure 1 , Figure 7 In one embodiment of the present invention, a selfie gimbal 10 is provided for fixing a shooting device such as a mobile phone 20, so that a user can hold the selfie gimbal 10 to collect images and videos with the mobile phone 20. The selfie gimbal 10 is essentially a selfie stick. The selfie gimbal 10 includes a supporting mechanism 100, a clamping mechanism 200, a motor 300 and a fan 400.

[0037] See also Figure 2 , Figure 6 and Figure 7 In some embodiments, the support mechanism 100 includes a rotating rod 110, a connecting rod 120, a first rotating shaft 130, and a second rotating shaft 140. The rotating rod 110, the connecting rod 120, and the second rotating shaft 140 can together form a support assembly 101. The first rotating shaft 130 is rotatably connected to the rotating rod 110, and the clamping mechanism 200 is disposed on the first rotating shaft 130, that is, the clamping mechanism 200 is rotatably connected to the rotating rod 110 through the first rotating shaft 130. At the same time, the rotating rod 110 is rotatably connected to the connecting rod 120 through the second rotating shaft 140. The rotating rod 110 can be relative to the connecting rod 120 in the following manner: Figure 3 The first position 11 shown and Fig.10 When rotating between the second position 12 shown in the figure, the central axis of the first rotating shaft 130 is set at an angle in the extension direction of the first position 11 and the extension direction of the second position 12. For example, the central axis of the first rotating shaft 130 in the extension direction of the first position 11 and the extension direction of the second position 12 can be perpendicular to each other.

[0038] See also Figure 4 , Figure 5 and Figure 8 The shape of the rotating rod 110 can be cylindrical or prismatic, etc. Of course, the rotating rod 110 can also be other regular or irregular shapes. The rotating rod 110 includes a first front surface 111, a first rear surface 112, a first left side surface 113, a first right side surface 114 and a first inclined surface 115. The first front surface 111 and the first rear surface 112 are oriented in the opposite direction. The first front surface 111 and the first rear surface 112 are spaced apart in the front-to-back direction, and the front-to-back direction is the horizontal longitudinal direction (Y-axis direction). The first left side surface 113 and the first right side surface 114 are oriented in the opposite direction. The first left side surface 113 and the first right side surface 114 are spaced apart in the left-right direction, and the left-right direction is the horizontal transverse direction (X-axis direction). Obviously, the first left side surface 113 is connected between one end of the first front surface 111 and the first rear surface 112, and the first right side surface 114 is connected between the other end of the first front surface 111 and the first rear surface 112. The first front surface 111, the first rear surface 112, the first left side 113 and the first right side 114 are connected to form a tubular structure, and the first inclined surface 115 is located at one end of the tubular structure, that is, the first inclined surface 115 is connected to the ends of the first front surface 111, the first rear surface 112, the first left side 113 and the first right side 114 at the same time, so that the first inclined surface 115 is located at the end of the rotating rod 110 close to the connecting rod 120.

[0039] When the rotating rod 110 is in the first position 11, the extension direction is the vertical direction (Z-axis direction), and the horizontal plane perpendicular to the vertical direction is taken as the reference plane 30. The angle A between the first inclined surface 115 and the reference plane 30 is 30° to 70°. For example, the angle A between the first inclined surface 115 and the reference plane 30 can be 45°. Of course, the value of the angle A can also be 30°, 60° or 70°, etc.

[0040] The first front surface 111 includes a first unit surface 111a, a second unit surface 111b and a third unit surface 111c. The first unit surface 111a is closer to the connecting rod 120 than the third unit surface 111c. The second unit surface 111b is connected between the first unit surface 111a and the third unit, that is, one end of the second unit surface 111b is connected to the first unit surface 111a, and the other end of the second unit surface 111b is connected to the third unit surface 111c. The first unit surface 111a and the third unit surface 111c are arranged at intervals along the front-to-back direction, and the two have the same orientation. Of course, the first unit surface 111a and the third unit surface 111c can be parallel to each other. The second unit surface 111b and the third unit surface 111c intersect and connect to form a certain angle, and the second unit surface 111b and the first unit surface 111a also intersect and connect to form a certain angle. The first rotating shaft 130 is arranged on the third unit surface 111c. When the rotating rod 110 is in the first position 11, the first rotating shaft 130 is arranged perpendicular to the third unit surface 111c, so that the central axis of the first rotating shaft 130 extends in the horizontal longitudinal direction. When the clamping mechanism 200 is connected to the first rotating shaft 130, the surface of the clamping mechanism 200 can be attached to the first unit surface 111a. When the first rotating shaft 130 drives the clamping mechanism 200 to rotate, by setting the second unit surface 111b, a good avoidance space can be provided for the rotation of the clamping mechanism 200, so as to avoid the interference between the clamping mechanism 200 and the rotating rod 110 during the rotation process, improve the stability of the rotation of the clamping mechanism 200, eliminate the vibration generated when the clamping mechanism 200 rotates, and when the mobile phone 20 follows the rotation of the clamping mechanism 200 to collect images or videos, the clarity and fidelity of the images or videos can be improved.

[0041] See also Figure 4 , Figure 5 and Fig. 9The shape of the connecting rod 120 can be cylindrical or prismatic, etc. Of course, the connecting rod 120 can also be other regular or irregular shapes. The connecting rod 120 includes a connecting portion 120a and a mounting portion 120b. The connecting portion 120a and the mounting portion 120b are bent and connected, for example, the connecting portion 120a and the mounting portion 120b can be perpendicular to each other. The rotating rod 110 is rotatably connected with the connecting portion 120a. The mounting portion 120b includes a plurality of protrusions 127. The protrusions 127 are arranged on one end of the mounting portion 120b away from the connecting portion 120a. The plurality of protrusions 127 are arranged at intervals along the width direction of the mounting portion 120b. For example, the number of the protrusions 127 can be three. Of course, the number of the protrusions 127 can be appropriately increased or decreased. Each protrusion 127 is provided with a through hole 127a, which can be a round hole, and the through holes 127a on each protrusion 127 are coaxially arranged. A rotating shaft can be installed in the through hole 127a, and the rotating shaft can be connected to the holding rod. Through the action of the rotating shaft, a rotational connection relationship between the holding rod and the mounting portion 120b can be achieved. In the first position 11, the central axis of the through hole 127a and the central axis of the first rotating shaft 130 are perpendicular to each other. For example, the central axis of the through hole 127a extends along the horizontal transverse direction (X-axis direction), and the central axis of the first rotating shaft 130 can extend along the horizontal longitudinal direction (Y-axis direction).

[0042] The connecting portion 120a includes a second front surface 121, a second rear surface 122, a second left side surface 123, a second right side surface 124 and a second inclined surface 125. The second front surface 121 and the second rear surface 122 are oriented in the opposite direction, and the second front surface 121 and the second rear surface 122 are spaced apart in the front-to-back direction, and the front-to-back direction is the horizontal longitudinal direction (Y-axis direction). The second left side surface 123 and the second right side surface 124 are oriented in the opposite direction, and the second left side surface 123 and the second right side surface 124 are spaced apart in the left-right direction, and the left-right direction is the horizontal transverse direction (X-axis direction). Obviously, the second left side surface 123 is connected between one end of the second front surface 121 and the second rear surface 122, and the second right side surface 124 is connected between the other end of the second front surface 121 and the second rear surface 122. The second front surface 121, the second rear surface 122, the second left side 123 and the second right side 124 are connected to form a tubular structure, and the second inclined surface 125 is located at one end of the tubular structure, that is, the second inclined surface 125 is connected to the ends of the second front surface 121, the second rear surface 122, the second left side 123 and the second right side 124 at the same time, so that the second inclined surface 125 is located at the end of the connecting portion 120a close to the rotating rod 110.

[0043] The included angle B between the second inclined surface 125 and the reference plane 30 can be 30° to 70°. For example, the included angle B between the second inclined surface 125 and the reference plane 30 can be 45°. Of course, the value of the included angle B can also be 30°, 60° or 70°, etc. The second inclined surface 125 and the first inclined surface 115 are parallel to each other. When the rotating rod 110 and the connecting rod 120 are rotatably connected, the first inclined surface 115 and the second inclined surface 125 are in contact with each other.

[0044] See also Figure 6 and Figure 7 , the rotating rod 110 can be a hollow structure, that is, the rotating rod 110 is surrounded by a first inner cavity 116. The first inclined surface 115 is provided with a first mounting hole 115a, and the first mounting hole 115a is connected to the outside and the first inner cavity 116 at the same time. Similarly, the connecting rod 120 can be a hollow structure, and the connecting rod 120 is surrounded by a second inner cavity 126. The second inclined surface 125 is provided with a second mounting hole 125a, and the second mounting hole 125a is connected to the outside and the second inner cavity 126 at the same time. The middle part of the second rotating shaft 140 is simultaneously penetrated by the first mounting hole 115a and the second mounting hole 125a, one end of the second rotating shaft 140 is received in the first inner cavity 116, and the other end of the second rotating shaft 140 is received in the second inner cavity 126. Therefore, by accommodating the second rotating shaft 140 in the first inner cavity 116 and the second inner cavity 126, the second rotating shaft 140 is hidden inside the rotating rod 110 and the connecting rod 120, and the user cannot observe the existence of the second rotating shaft 140 from the outside, thereby improving the overall consistency of the appearance of the entire selfie gimbal 10 and preventing the second rotating shaft 140 from affecting the appearance of the selfie gimbal 10. At the same time, the second rotating shaft 140 makes full use of the space of the first inner cavity 116 and the second inner cavity 126, avoiding the second rotating shaft 140 from occupying the installation space outside the rotating rod 110 and the connecting rod 120, making the selfie gimbal 10 more compact in structure. Furthermore, the rotating rod 110 and the connecting rod 120 are both set to be hollow, which can reduce the total weight of the selfie gimbal 10, thereby improving the comfort of operation of the selfie gimbal 10.

[0045] See also Figure 4 and Figure 5When the rotating rod 110 is in the first position 11, the central axis of the first rotating shaft 130 extends along the horizontal longitudinal direction (Y-axis direction), and the rotating rod 110 is in a vertical state. At this time, the first unit surface 111a is butted against the end of the second front surface 121 and is flush with each other, the first rear surface 112 is butted against the end of the second rear surface 122 and is flush with each other, the first left side surface 113 is butted against the end of the second left side surface 123 and is flush with each other, and the first right side surface 114 is butted against the end of the second right side surface 124 and is flush with each other. In addition, the edges of the first inclined surface 115 and the second inclined surface 125 are aligned with each other, that is, with the reference plane 30 as a reference, the orthographic projections of the first inclined surface 115 and the second inclined surface 125 on the reference plane 30 completely overlap.

[0046] See also Fig.10 , Fig.11 and Fig.12 , after the rotating rod 110 rotates 180° from the first position 11 relative to the connecting rod 120, the rotating rod 110 will be in the second position 12. At this time, the first unit surface 111a is butted against the end of the second rear surface 122 and the two are perpendicular to each other, the first rear surface 112 is butted against the end of the second front surface 121 and the two are perpendicular to each other, the first left side surface 113 is butted against the end of the second right side surface 124 and they are flush with each other, and the second left side surface 123 is butted against the end of the first right side surface 114 and they are flush with each other. In addition, the edges of the first inclined surface 115 and the second inclined surface 125 are still aligned with each other, that is, with the reference plane 30 as a reference, the orthographic projections of the first inclined surface 115 and the second inclined surface 125 on the reference plane 30 completely overlap. When the rotating rod 110 is in the second position 12, the central axis of the first rotating shaft 130 extends in the vertical direction (Z-axis direction). In other words, when the rotating rod 110 rotates from the first position 11 to the second position 12, the central axis of the first rotating shaft 130 will be transformed from a horizontal state to a vertical state; at the same time, the rotating rod 110 is in a horizontal state.

[0047] See also Figure 7 The motor 300 can be housed in the first inner cavity 116 of the rotating rod 110, and the first rotating shaft 130 is connected to the motor 300, so that the motor 300 can drive the first rotating shaft 130 to rotate, and then the first rotating shaft 130 drives the clamping mechanism 200 to rotate. When a torque is applied to the rotating rod 110 by hand, the rotating rod 110 is also rotated relative to the connecting rod 120 around the second rotating shaft 140. Therefore, the rotation of the clamping mechanism 200 relative to the rotating rod 110 is driven by the motor 300, while the rotation of the rotating rod 110 relative to the connecting rod 120 is driven manually.

[0048] If two motors are provided, one of the motors rotates the central axis extending along the horizontal direction of the clamping mechanism 200 and the mobile phone 20, and the other motor rotates the central axis extending along the vertical direction of the clamping mechanism 200 and the mobile phone 20, thereby realizing the rotation of multiple degrees of freedom of the mobile phone 20 to achieve multi-angle shooting. However, this will increase the manufacturing cost due to the increase in the number of motors, and also increase the weight and power consumption of the entire selfie gimbal 10, and also make the structure of the selfie gimbal 10 more complicated.

[0049] For the selfie gimbal 10 of the above embodiment, when the rotating rod 110 is in the first position 11, the central axis of the first rotating shaft 130 extends in the horizontal direction. When the motor 300 rotates, the clamping mechanism 200 and the mobile phone 20 rotate around the central axis extending in the horizontal direction, realizing the rotation of the first degree of freedom of the mobile phone 20. When the clamping mechanism 200 and the mobile phone 20 need to rotate around the central axis extending in the vertical direction to realize the rotation of the second degree of freedom of the mobile phone 20, it is only necessary to rotate the rotating rod 110 to the second position 12. At this time, the central axis of the first rotating shaft 130 will be transformed from a horizontal state to a vertical state. During the operation of the motor 300, the second degree of freedom of the mobile phone 20 can be smoothly realized. Of course, during the rotation of the rotating rod 110, the position of the connecting rod 120 should remain unchanged. Therefore, by providing the second rotating shaft 140, the first inclined surface 115 and the second inclined surface 125, when there is only one motor 300 and the position of the connecting rod 120 remains unchanged, the rotation of the clamping mechanism 200 and the mobile phone 20 with two degrees of freedom can also be achieved, thereby achieving multi-angle shooting of the mobile phone 20. In this way, the number of motors 300 installed can be saved, thereby reducing the manufacturing cost of the selfie gimbal 10 and simplifying its structure, while reducing the weight and power consumption of the entire selfie gimbal 10, and can also improve the playability of the selfie gimbal 10 to a certain extent.

[0050] See also Fig.13 , Fig.15 and Fig.16 In some embodiments, the clamping mechanism 200 includes a bearing block 210, a first clamping assembly 220, a second clamping assembly 230, an abutment member 240, and a power source 250. The bearing block 210 is mounted on the first rotating shaft 130, and the structures of the first clamping assembly 220 and the second clamping assembly 230 can be completely the same. For example, the first clamping assembly 220 and the second clamping assembly 230 both include a slider 231, two clamping blocks 232, a mounting block 233, a third rotating shaft 234, a guide rod 235, and a spring.

[0051] The first clamping assembly 220 and the second clamping assembly 230 are both arranged at opposite ends in the length direction of the supporting block 210, so that the first clamping assembly 220 and the second clamping assembly 230 are spaced apart along the length direction of the supporting block 210, so a first gap 222 is formed between the first clamping assembly 220 and the second clamping assembly 230, and the first gap 222 is used to cooperate with the mobile phone 20, and the first gap 222 is actually formed by the gap between the clamping blocks 232 of different clamping assemblies.

[0052] For the same clamping assembly, the slider 231 is slidably connected to the bearing block 210, so that the slider 231 can slide back and forth in the length direction of the bearing block 210. The third rotating shaft 234 is inserted into the mounting block 233, and the third rotating shaft 234 is rotatably connected to the slider 231, and the central axis of the third rotating shaft 234 extends along the width direction of the bearing block 210. Two clamping blocks 232 are respectively arranged at opposite ends of the mounting block 233, so that the two clamping blocks 232 are spaced apart in the width direction of the bearing block 210, and a second gap 232a is formed between the two clamping blocks 232, and the second gap 232a is also used to cooperate with the mobile phone 20.

[0053] The slider 231 is provided with a recessed space 231a, and the mounting block 233 is received in the recessed space 231a. The recessed space 231a can reduce the total weight of the slider 231 on the one hand, and can make the mounting block 233 fully utilize the mounting space formed by the recessed space 231a on the other hand, so as to avoid the mounting block 233 occupying other mounting space outside the slider 231, thereby making the first clamping assembly 220 and the second clamping assembly 230 more compact in structure.

[0054] The bearing block 210 is also provided with a sliding hole 213a, which extends along the length direction of the bearing block 210. The guide rod 235 can be fixedly connected to the slider 231, and the guide rod 235 and the sliding hole 213a are slidably matched. Through the cooperation between the guide rod 235 and the sliding hole 213a, the sliding accuracy and stability of the slider 231 relative to the bearing block 210 can be improved. At the same time, when the slider 231 slides away from the bearing block 210, the width of the first gap 222 can be increased, and when the slider 231 slides close to the bearing block 210, the width of the gap can be reduced. Therefore, through the movement of the slider 231 relative to the bearing block 210, the size of the first gap 222 can be adjusted, so that the first gap 222 can be matched with mobile phones 20 of different models and sizes. The spring can be accommodated in the sliding hole 213a and sleeved on the guide rod 235, one end of the spring can be fixed on the bearing block 210, and the other end of the spring can be fixed on the slider 231. When the slider 231 slides away from the supporting block 210, the spring stores energy. When the matching relationship between the first gap 222 and the mobile phone 20 is released, the slider 231 can automatically move closer to the supporting block 210 under the action of the spring elastic force, that is, the spring plays the role of resetting the slider 231.

[0055] The abutment member 240 is located between the first clamping assembly 220 and the second clamping assembly 230. The abutment member 240 is rotatably connected to the bearing block 210. The abutment member 240 can rotate around the central axis extending along the length direction of the bearing block 210. When the mobile phone 20 is matched with the second gap 232a, the abutment member 240 can be rotated to a certain appropriate position and abut against the mobile phone 20, thereby improving the stability of the mobile phone 20. The abutment member 240 is also concavely formed with a sinking groove 241. When the abutment member 240 is rotated to another appropriate position, the mobile phone 20 is matched with the sinking groove 241, thereby also improving the stability of the mobile phone 20.

[0056] In some embodiments, the bearing block 210 is recessed to form a first groove 211 and a second groove 212. The recess depth of the first groove 211 is less than that of the second groove 212, and the recess depths of the two second grooves 212 can be the same. There is one first groove 211 and two second grooves 212. The first groove 211 is centrally arranged and the second grooves 212 are located on opposite sides of the first groove 211. The bearing block 210 has a step surface 213, which is located at the connection between the first groove 211 and the second groove 212, and the sliding hole 213a is provided on the step surface 213. The slider 231 can be accommodated in the second groove 212, and the clamping block 232 and the abutment 240 can be accommodated in the first groove 211. The slider 231 can abut against the step surface 213, thereby limiting the limit sliding distance of the slider 231, that is, the step surface 213 plays a limiting role in the sliding of the slider 231.

[0057] See also Fig.14 and Fig.15 The bearing block 210 is also provided with a receiving cavity 214 and a plug hole 215. The power supply 250 is used to control the motor 300 (such as Figure 7 ) to provide energy. The socket 215 connects the outside world and the accommodating chamber 214, the charging base of the power supply 250 is accommodated in the socket 215, and the other parts of the power supply 250 are accommodated in the accommodating chamber 214. When the charging base is connected to an external charging device, the power supply 250 can be charged to ensure that the power supply 250 can be recycled.

[0058] When the rotating rod 110 is in the first position 11, the clamping blocks 232 of the first clamping assembly 220 and the second clamping assembly 230 can be rotated relative to the slider 231 away from the bearing block 210. At this time, the first gap 222 is formed between the clamping blocks 232 of the two clamping assemblies. At the same time, the slider 231 slides away from the bearing block 210 to increase the size of the first gap 222, ensuring that the mobile phone 20 can be placed in the first gap 222. When the mobile phone 20 is placed in the first gap 222 with a larger size, the slider 231 moves close to the bearing block 210 under the action of the spring force, so that the clamping blocks 232 of the two clamping assemblies move toward each other until they abut against the mobile phone 20. At this time, the size of the first gap 222 is reduced, so that the mobile phone 20 is stably and reliably clamped by the clamping blocks 232 in the first gap 222 with a reduced size. When the mobile phone 20 is clamped in the first gap 222, the back 22 of the mobile phone 20 is arranged toward the bearing block 210, the front 21 (display surface) of the mobile phone 20 is arranged away from the bearing block 210, and the side 23 of the mobile phone 20 is in contact with the clamping block 232. Obviously, the side 23 of the mobile phone 20 is connected between the front 21 and the back 22. Of course, in order to avoid interference with the fixation of the mobile phone 20, the abutment 240 can be rotated and accommodated in the first groove 211 of the bearing block 210. In the process of the mobile phone 20 being clamped, the weight of the mobile phone 20 can be borne by the clamping block 232 of one of the clamping components, that is, the weight of the mobile phone 20 directly acts on the clamping block 232 of one of the clamping components. In short, the clamping blocks 232 on the two clamping components can apply a force along the length direction or width direction of the mobile phone 20 itself to fix the mobile phone 20 in the first gap 222.

[0059] When the rotating rod 110 is in the second position 12, the mobile phone 20 will be clamped in the second gap 232a of the first clamping assembly 220 and the second clamping assembly 230 at the same time, so the mobile phone 20 will no longer be clamped in the first gap 222. When the mobile phone 20 is clamped in the second gap 232a, the front 21 and the back 22 of the mobile phone 20 are simultaneously in contact with the two clamping blocks 232 on the same clamping assembly, that is, the two clamping blocks 232 on the same clamping assembly apply a force along the thickness direction of the mobile phone 20 to fix the mobile phone 20 in the second gap 232a. At this time, the gravity of the mobile phone 20 can directly act on the slider 231 and the bearing block 210, and the clamping block 232 can no longer bear the gravity of the mobile phone 20. When the mobile phone 20 is fixed in the second gap 232a, one of the side surfaces 23 of the mobile phone 20 extending in the length direction can be set toward the bearing block 210, that is, the "horizontal clamping" of the mobile phone 20 is realized. Alternatively, one of the side surfaces 23 extending along the width direction of the mobile phone 20 is arranged toward the carrier block 210, that is, the "vertical clamping" of the mobile phone 20 is realized. It can be understood that for "vertical clamping", before the mobile phone 20 is clamped in the second gap 232a, the abutment 240 can be rotated away from the carrier block 210 to a suitable position. When the mobile phone 20 is clamped, the end of the abutment 240 abuts against the back of the mobile phone 20, thereby further improving the clamping stability of the mobile phone 20. For "horizontal clamping", before the mobile phone 20 is clamped in the second gap 232a, the abutment 240 can be moved close to the carrier block 210 until it is accommodated in the first groove 211. When the mobile phone 20 is clamped, a part of the mobile phone 20 can cooperate with the sink 241 on the abutment 240. By the cooperation of the mobile phone 20 with the sink 241 and the second gap 232a at the same time, the clamping stability of the mobile phone 20 is further improved. Of course, the mobile phone 20 can also be clamped in the second gap 232a of the first clamping assembly 220 alone. In this case, the second clamping assembly 230 forms an abutment against the side 23 of the mobile phone 20, and the mobile phone 20 can also be fixed. The mobile phone 20 can also be clamped in the second gap 232a of the second clamping assembly 230 alone. In this case, the first clamping assembly 220 forms an abutment against the side 23 of the mobile phone 20, and the mobile phone 20 can also be fixed.

[0060] See also Fig.13 and Fig.14 When the clamping mechanism 200 does not need to clamp the mobile phone 20, the slider 231 will be accommodated in the second groove 212 and abut against the step surface 213. The clamping blocks 232 on the two clamping components can be rotated so that the clamping blocks 232 are accommodated in the first groove 211. Similarly, the abutting member 240 can be rotated to be accommodated in the first groove 211, thereby reducing the volume of the clamping mechanism 200 and facilitating the storage and carrying of the selfie gimbal 10.

[0061] By setting the first gap 222, the first clamping assembly 220 and the second clamping assembly 230 can apply a force along the length direction or width direction of the mobile phone 20 to clamp the mobile phone 20. In addition, by setting the second gap 232a, the first clamping assembly 220 and the second clamping assembly 230 can also apply a force along the thickness of the mobile phone 20 to clamp the mobile phone 20. In view of the fact that the rotating rod 110 is in the second position 12 and the central axis of the first rotating shaft 130 extends in the vertical direction, when the mobile phone 20 is clamped along its thickness direction, it can be ensured that the mobile phone 20 smoothly captures images or videos to meet the shooting requirements. Otherwise, when the mobile phone 20 is still clamped in the first gap 222 when the rotating rod 110 is in the second position 12, the mobile phone 20 will be set "upward" and cannot capture surrounding images and videos, thereby failing to meet the shooting requirements. Therefore, by setting the first gap 222 to match the rotating rod 110 in the first position 11, and by setting the second gap 232a to match the rotating rod 110 in the second position 12, it is ensured that the mobile phone 20 can smoothly shoot at different positions of the rotating rod 110, thereby meeting different shooting requirements.
