Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to a bracket. Background Technology

[0002] Currently, most phone stands use magnetic attachment to secure the phone. However, this type of stand requires the phone to have magnetic attachment capabilities; phones without magnetic attachment cannot use the stand, resulting in poor compatibility. To solve this problem, stands that use two clamping arms to hold the phone have appeared on the market. By clamping the phone, they secure it without relying on magnetic attachment, thus improving the stand's compatibility.

[0003] However, existing clamping arm holders require users to press down on both clamping arms to shorten the distance between them when securing a phone. Since the distance between the two clamping arms is relatively large when the holder is not in use, users need to use both hands to press down on the arms while simultaneously placing the phone between them, which is inconvenient for users. Utility Model Content

[0004] In view of this, the present invention provides a bracket to solve the problem that existing brackets require both hands to squeeze the clamping arms, which leads to inconvenience in operation.

[0005] This application provides a support, including a base, an operating member, a transmission structure, and two clamping arms. The operating member is rotatably mounted on the base, and the two clamping arms are disposed opposite to each other on the base. The transmission structure is connected to the operating member, and the operating member is transmittedly connected to at least one of the clamping arms through the transmission structure. When the operating member rotates, it can drive one of the clamping arms to move relative to the other clamping arm through the transmission structure.

[0006] The bracket provided by this utility model has a rotatable operating component on the base. The operating component and the clamping arm are connected by a transmission structure to form a transmission cooperation effect. When the operating component rotates relative to the base, it can drive the clamping arm to move through the transmission structure for clamping electronic equipment. The rotation operation is simple and can be operated with one hand, making it convenient for users. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0010] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0011] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0012] Please see Figures 1 to 11 This utility model provides a bracket 100 for clamping and supporting electronic devices. The bracket 100 includes a base 10, an operating member 12, two clamping arms 14, and a transmission structure 16. The operating member 12 is rotatably mounted on the base 10, allowing it to rotate relative to the base 10. The two clamping arms 14 are disposed opposite to each other on the base 10, and at least one clamping arm 14 is movably engaged with the base 10, thereby adjusting the distance between the two clamping arms 14 for clamping electronic devices such as mobile phones. The electronic device can be an electronic device with a protective case or an electronic device without a protective case.

[0013] Optionally, the two clamping arms 14 of the bracket 100 clamp the protective shell 200, thereby indirectly clamping the electronic device located inside the protective shell 200. The protective shell 200 includes a back plate 201 and a frame 202. The frame 202 is connected to the periphery of the back plate 201 and forms an accommodating space with the back plate 201 to accommodate electronic devices such as mobile phones. The base 10 is located on the side of the back plate 201 away from the accommodating space, and the two clamping arms 14 clamp the opposite sides of the frame 202.

[0014] The transmission structure 16 is connected to the operating member 12, and the operating member 12 is connected to at least one clamping arm 14 via the transmission structure 16. That is, the transmission structure 16 is provided between the operating member 12 and at least one clamping arm 14 to form a transmission engagement between the operating member 12 and the clamping arm 14. When the operating member 12 rotates, it can drive one clamping arm 14 to move relative to the other clamping arm 14 through the transmission structure 16, adjusting the distance between the two clamping arms 14 to clamp the electronic device. By setting the operating member 12 on the base 10 and simultaneously providing the transmission structure 16 between the operating member 12 and the clamping arm 14, the user can control the clamping arm 14 to clamp the electronic device by rotating the operating member 12. This is simple to operate, can be done with one hand, and is convenient for users. Furthermore, the bracket 100 fixes the electronic device by clamping, and by controlling the distance between the two clamping arms 14, it can adapt to electronic devices of different sizes, improving the compatibility of the bracket 100.

[0015] When the operating member 12 rotates, it causes one clamping arm 14 to move relative to the other clamping arm 14 to clamp the electronic device. This can mean that by rotating the operating member 12, one clamping arm 14 moves closer to the other clamping arm 14 until the two clamping arms 14 clamp the electronic device. Alternatively, it can mean that by rotating the operating member 12, one clamping arm 14 moves away from the other clamping arm 14, so that the distance between the clamping parts of the two clamping arms 14 is greater than the width of the electronic device. Then, the operating member 12 is released, and the two clamping arms 14 achieve an automatic reset effect and automatically clamp the electronic device. In an optional example, when the operating member 12 rotates in one direction, it can bring one clamping arm 14 closer to the other clamping arm 14 to clamp the electronic device. When the operating member 12 rotates in the opposite direction, it can move one clamping arm 14 away from the other clamping arm 14 to release the electronic device, facilitating the removal and placement of the electronic device.

[0016] The transmission structure 16 is connected to at least one clamping arm 14 in a transmission manner, meaning that when both clamping arms 14 are in movable engagement with the base 10, both clamping arms 14 are movable arms. The transmission structure 16 is connected to both clamping arms 14 in a transmission manner. When the operating member 12 rotates, both clamping arms 14 can move relative to the base 10 under the action of the transmission structure 16. Alternatively, one clamping arm 14 can be in movable engagement with the base 10 to form a clamping arm, while the other clamping arm 14 is fixed relative to the base 10 to form a fixed arm. The transmission structure 16 is connected to the movable arm in a transmission manner. When the operating member 12 rotates, the fixed arm remains stationary, while the movable arm moves relative to the fixed arm. That is, when the rotation of the operating member 12 drives one clamping arm 14 to move relative to the other clamping arm 14, it can mean that one clamping arm 14 remains stationary while the other clamping arm 14 moves relative to the stationary clamping arm 14. It can also mean that both clamping arms 14 move, and the two clamping arms 14 move towards or away from each other.

[0017] In an alternative example, both clamping arms 14 are movably engaged with the base 10, and the transmission structure 16 is connected to the two clamping arms 14. When the operating member 12 rotates, the two clamping arms 14 can be driven to move together through the transmission structure 16. When the two clamping arms 14 move towards each other, a centering clamping effect can be formed.

[0018] The transmission structure 16 is a gear and rack structure, comprising a gear 18 and a rack 20. The gear 18 is fixed relative to the operating member 12 and coaxially arranged, meaning their rotation axes coincide. The gear 18 can rotate with the operating member 12. The rack 20 is fixed relative to the clamping arm 14 and meshes with the gear 18. The rack 20 is movably engaged with the base 10. When the gear 18 rotates under the action of the operating member 12, it drives the rack 20 to perform linear motion, thereby driving the clamping arm 14 to perform linear motion, causing the two clamping arms 14 to move closer together or further apart. The engagement of the gear 18 and rack 20 not only stably converts rotational motion into linear motion, but also utilizes a mature manufacturing process, which helps reduce production difficulty and costs.

[0019] Optionally, both clamping arms 14 are movably connected to the base 10, and the transmission structure 16 is drively connected to both clamping arms 14. There are two racks 20, each connected to one of the two clamping arms 14. The two racks 20 are located on opposite sides of the gear 18 and mesh with the gear 18. When the gear 18 rotates, it drives the two racks 20 to move in opposite directions, thereby causing the two clamping arms 14 to move closer together or further apart.

[0020] Understandably, gear 18 and operating member 12 can be integrally formed or separately connected. Similarly, rack 20 and clamping arm 14 can be integrally formed or separately connected. In an optional example, gear 18 and operating member 12 are integrally formed, and rack 20 and clamping arm 14 are integrally formed, eliminating the fixing process, improving strength, and preventing loosening at the connection point that would affect the transmission effect.

[0021] In other embodiments, the transmission structure 16 can also be other structures, as long as it can convert rotational motion into linear motion. For example, the transmission structure 16 can be a cam structure, which includes a cam groove and a cam shaft. One of the operating member 12 and the rack 20 is provided with a cam groove, and the other is provided with a cam shaft. The cam groove extends along the rotation direction of the operating member 12 to form an arc-shaped groove. The cam shaft is eccentrically set with the operating member 12, that is, their central axes are not collinear. The cam shaft is movably inserted into the cam groove. When the operating member 12 rotates, the cam shaft will squeeze the groove wall of the cam groove, thereby pushing the clamping arm 14 to slide.

[0022] In one embodiment, a clamping space 22 is formed between two clamping arms 14 for clamping electronic devices. The operating member 12 can control the two clamping arms 14 to move closer or further apart to adjust the size of the clamping space 22 so as to clamp electronic devices of a corresponding size.

[0023] Each clamping arm 14 includes a connecting portion 21 and a clamping portion 23. The connecting portion 21 is movably mounted on the base 10 and connected to the transmission structure 16. The clamping portion 23 is located at the end of the connecting portion 21 away from the transmission structure 16 and on the outside of the base 10. The rack 20 is located at the end of the connecting portion 21 away from the clamping portion 23. The clamping portion 23 is set at an angle to the connecting portion 21. This angle can be, for example, a right angle or an acute angle, meaning the clamping portion 23 can be perpendicular to the connecting portion 21 or inclined relative to it. The two clamping portions 23 are spaced apart and opposite each other, and the two clamping portions 23 cooperate with one side of the base 10 to form a clamping space 22. When the operating member 12 rotates, it drives the gear 18 to rotate. The gear 18 drives the rack 20 to move linearly, which in turn drives the connecting portion 21 connected to it to move. The connecting portion 21 then drives the clamping portion 23 to move, so that the two clamping portions 23 move closer together to clamp the electronic device, or move away to release the electronic device. Optionally, the two connecting parts 21 are located on opposite sides of the gear 18, the rack 20 is fixed relative to the connecting parts 21, and the rack 20 is located at the end of the connecting part 21 away from the clamping part 23.

[0024] Understandably, the connecting portion 21 may be entirely hidden within the base 10, or it may be partially hidden within the base 10 and partially protruding outside the base 10. For example, the connecting portion 21 partially protrudes outside the base 10, and the two clamping portions 23, the portions of the two connecting portions 21 protruding outside the base 10, and one side of the base 10 cooperate to form a clamping space 22.

[0025] The operating element 12 is located on the side of the base 10 away from the clamping space 22. That is, the operating element 12 is located on the side of the connecting part 21 away from the clamping space 22, so that the user will not be affected by the electronic device when rotating the operating element 12, making it convenient for the user to use.

[0026] An operating part 24 protrudes from the side of the operating member 12 away from the clamping space 22. The gear 18 and the operating part 24 are located on opposite sides of the operating member 12, that is, the operating part 24 is located on the side of the operating member 12 away from the gear 18. The operating part 24 is fixed relative to the operating member 12 and protrudes from the surface of the operating member 12. The user can pinch the operating part 24, which provides a better point of leverage and makes it easier for the user to rotate the operating member 12.

[0027] Optionally, the operating part 24 is elongated and extends from one end of the operating member 12 to the other end to increase the length of the operating part 24, making it easier for the user to rotate the operating member 12 via the operating part 24. The operating part 24 is located at the middle of the operating member 12 along a direction perpendicular to the direction of extension of the operating part 24.

[0028] In other embodiments, the operating member 12 may also be located on the circumferential side of the base 10, between the side of the base 10 facing the clamping space 22 and the side facing away from the clamping space 22. The side facing the clamping space 22 and the side facing away from the clamping space 22 are the opposite sides of the base 10 in the thickness direction. In this case, the operating member 12 may be rod-shaped, and the operating part 24 may be located on the circumferential side of the operating member 12. The operating member 12 can drive the gear 18 to rotate through the bevel gear set. It can be understood that the operating part 24 may be an anti-slip texture provided on the outer side of the operating member 12, or a handle extending radially along the operating member 12. The handle is fixed relative to the operating member 12, and the user drives the operating member 12 to rotate through the handle.

[0029] The base 10 has a receiving cavity 26 located in the middle of the base 10. The gear 18 and the operating member 12 are located within the receiving cavity 26, and the rack 20 is at least partially located within the receiving cavity 26 to mesh with the gear 18. One end of the receiving cavity 26 extends to the side of the base 10 opposite to the clamping space 22, forming an opening. The operating member 12 is mounted at the opening, exposing the operating member 12. The gear 18 is located between the operating member 12 and the clamping space 22. Optionally, the operating member 12 is rotatably disposed in the receiving cavity 26, and the operating part 24 protrudes outside the receiving cavity 26. By providing the receiving cavity 26 on the base 10 to accommodate the operating member 12 and the transmission structure 16, the compactness of the support 100 structure can be improved, which is beneficial for reducing the thickness of the support 100. Optionally, the receiving cavity 26 is circular, and the shape of the operating member 12 is adapted to the shape of the receiving cavity 26 to avoid the base 10 affecting the rotation of the operating member 12.

[0030] Understandably, a limiting structure can be provided between the operating member 12 and the base 10 to limit the operating member 12 axially in the receiving cavity 26 and prevent the operating member 12 from detaching from the receiving cavity 26. For example, a limiting groove can be provided on the inner wall of the receiving cavity 26, and the periphery of the base 10 can be inserted into the limiting groove to form an axial limiting effect on the operating member 12 without affecting its rotation.

[0031] The base 10 is also provided with a sliding groove 28 that communicates with the receiving cavity 26. The sliding groove 28 extends from the receiving cavity 26 to the circumferential side of the base 10 to connect the receiving cavity 26 with the outside, forming a through-base 10 effect. The connecting part 21 is movably inserted through the sliding groove 28, so that the clamping arm 14 forms a sliding fit with the base 10, and the clamping part 23 is located on the outside of the sliding groove 28. When the clamping arm 14 moves under the drive of the operating member 12, the sliding groove 28 can guide and limit the clamping arm 14 to prevent the clamping arm 14 from shaking during the movement. Optionally, the receiving cavity 26 is cylindrical, and the sliding groove 28 penetrates the base 10 radially through the receiving cavity 26 to connect the receiving cavity 26 with the outside.

[0032] In an optional example, the base 10 is provided with two sliding grooves 28, which are symmetrically arranged on opposite sides of the base 10, and the two clamping arms 14 are respectively slidably engaged with a corresponding sliding groove 28.

[0033] The base 10 includes a main body 30 and a cover plate 32 connected to the main body 30. A receiving cavity 26 penetrates the main body 30 in the thickness direction, and a sliding groove 28 penetrates the main body 30 in a direction perpendicular to the thickness direction. The operating member 12 and the cover plate 32 are respectively disposed on opposite sides of the main body 30 in the thickness direction to close the receiving cavity 26. The transmission structure 16 is located between the cover plate 32 and the operating member 12. During assembly, the main body 30 and the cover plate 32 can be separated first. After the clamping arm 14 and the operating member 12 form a transmission engagement, the cover plate 32 can be installed on the main body 30, which helps to reduce assembly difficulty. At the same time, the connecting part 21 of the clamping arm 14 is located between the main body 30 and the cover plate 32 to prevent the clamping arm 14 from separating from the base 10.

[0034] Optionally, the main body 30 is annular, the receiving cavity 26 is located inside the main body 30, and the sliding groove 28 is provided on the main body 30 and penetrates the main body 30 radially.

[0035] The cover plate 32 is at least partially located within the receiving cavity 26 to enhance the compactness of the base 10 and reduce its thickness. The outer periphery of the cover plate 32 has multiple spaced mounting protrusions 33, each with a through-hole 35. The main body 30 has a recess 37 on the side near the clamping space 22, which communicates with the receiving cavity 26. A mounting post 39 is located within the recess 37, and the mounting protrusions 33 are situated within the recess 37, with the mounting post 39 passing through the through-hole 35, to provide a positioning effect for the cover plate 32 during assembly. Optionally, the cover plate 32 and the main body 30 can be fixed together by applying adhesive or by bolting the portion of the mounting post 39 extending beyond the mounting protrusion 33.

[0036] The main body 30 and the cover plate 32 are each provided with an extension 41. The extension 41 extends in a direction perpendicular to the thickness direction and extends outward in the circumferential direction of the base 10. The two extensions 41 are arranged at intervals along the thickness direction of the main body 30, thereby forming an installation space between the two extensions 41. The bracket 100 also includes a hanging rope 58, which is a sheet-like structure with its two ends stacked and pressed together and fixed between the two extensions 41. The hanging rope 58 protrudes out of the extensions 41 and forms a hanging hole 60. When the user goes out, the rope can be passed through the hanging hole 60 to hang the bracket 100 on his hand instead of holding it, making it convenient to carry.

[0037] In one embodiment, the bracket 100 further includes a support member 34, which is located on the side of the base 10 away from the clamping space 22, i.e., away from the electronic device, and is rotatably connected to the base 10. The support member 34 can rotate relative to the base 10 to switch between a closed state and an open state. In the closed state, the support member 34 and the base 10 are stacked to reduce the overall volume of the bracket 100 in the closed state, making it convenient for storage and carrying. In the open state, the support member 34 forms an angle with the base 10 to support the electronic device clamped by the clamping arm 14.

[0038] The support member 34 is annular and is rotatably mounted on the main body 30 and surrounds the outer periphery of the receiving cavity 26. The operating member 12 is located in the inner ring of the support member 34 to prevent it from affecting the rotation of the operating member 12 located in the receiving cavity 26.

[0039] A hinge 36 is fixedly mounted on the base 10. One end of the support member 34 is rotatably connected to the hinge 36 via a pivot 38. The support member 34 can drive the pivot 38 to rotate relative to the hinge 36 and the base 10. A mating flat portion 40 can be provided between the pivot 38 and the hinge 36. When the pivot 38 rotates relative to the hinge 36 with the support member 34, the flat portion 40 increases the damping force between the pivot 38 and the hinge 36, thereby positioning the support member 34 in the corresponding position and creating a hovering effect, thus achieving support at different angles.

[0040] The support member 34 is provided with a positioning pin 42, and the end of the rotating shaft 38 located inside the support member 34 is provided with an annular groove. The positioning pin 42 is located on the radial side of the rotating shaft 38 and is partially located in the annular groove, so as to form a limiting effect in the axial direction of the rotating shaft 38 and prevent the rotating shaft 38 from separating from the support member 34.

[0041] In one embodiment, the operating member 12 is provided with a one-way ratchet 48. When the operating member 12 rotates, it drives the one-way ratchet 48 to rotate together. The base 10 is provided with a pawl 50 that cooperates with the one-way ratchet 48, and the pawl 50 can move relative to the base 10. The one-way ratchet 48 includes a plurality of ratchet teeth 52, which surround the circumferential outer side of the gear 18. When the pawl 50 is located between two adjacent ratchet teeth 52, the pawl 50 can cooperate with the one-way ratchet 48 to form a one-way limiting effect. Therefore, through the cooperation of the pawl 50 and the one-way ratchet 48, no limiting effect is formed in the clamping direction of the operating member 12 (i.e., the direction of rotation of the operating member when the two clamping arms come together to clamp the electronic device), so that the pawl 50 and the one-way ratchet 48 will not affect the rotation of the operating member in the clamping direction, and will not affect the clamping arm 14 clamping the mobile phone. A limiting effect is formed in the opening direction of the operating member 12 (i.e., the direction of rotation of the operating member when the two clamping arms move away from each other and release the electronic device). The opening direction and the clamping direction are opposite directions. The cooperation of the pawl 50 and the one-way ratchet 48 can prevent the operating member 12 from rotating in the opening direction, thereby preventing the two clamping arms 14 from moving away and releasing the electronic device in the clamping state.

[0042] Optionally, the one-way ratchet 48 and the gear 18 are located on the same side of the operating member 12, and the one-way ratchet 48, the gear 18 and the operating member are coaxially arranged, and the one-way ratchet 48, the gear 18 and the operating member 12 are integrally formed.

[0043] The ratchet 52 has a first inclined surface 53, and the pawl 50 has a second inclined surface 55. When the pawl 50 is located between two adjacent ratchet teeth 52, the second inclined surface 55 is opposite to the first inclined surface 53 of one of the ratchet teeth 52, and the two are inclined in the same direction. When the operating member 12 drives the one-way ratchet 48 to rotate so that the first inclined surface 53 moves toward the opposite second inclined surface 55, the first inclined surface 53 will squeeze the second inclined surface 55 and push the pawl 50 to move out of the two ratchet teeth 52. At this time, the pawl 50 will not prevent the operating member 12 from rotating. Under the action of the operating member 12, the clamping arm 14 moves toward the other clamping arm 14. That is, the rotation direction in which the operating member 12 drives the first inclined surface 53 to move toward the opposite second inclined surface 55 is the clamping direction.

[0044] The ratchet 52 has a straight surface on the side facing away from the first inclined plane 53, and the pawl 50 also has a straight surface on the side facing away from the second inclined plane 55. When the pawl 50 is located between two adjacent ratchet teeth 52, the second inclined plane 55 of the pawl 50 is opposite to the first inclined plane 53 of one of the ratchet teeth 52, and the straight surface of the pawl 50 is opposite to the straight surface of the other ratchet tooth 52. When the operating member 12 wants to drive the one-way ratchet 48 to rotate so that the first inclined plane 53 moves away from the second 55, the straight surface of the pawl 50 will fit with the straight surface of the ratchet tooth 52 to prevent the operating member 12 from rotating in that direction, which is the opening direction. When the pawl 50 is disengaged from between the two ratchet teeth 52, the two straight surfaces will not fit together, and at this time the pawl 50 will not prevent the operating member 12 from rotating in the opening direction.

[0045] The base 10 is provided with a movable component 44, which can move relative to the base 10. A pawl 50 is disposed on the movable component 44, that is, the pawl 50 is connected to the base 10 through the movable component 44. When the movable component 44 moves relative to the base 10, it drives the pawl 50 to move together, so that the pawl 50 is inserted between two adjacent ratchet teeth 52, so as to limit the operation member 12 in the opening direction, or to make the pawl 50 retract from between two adjacent ratchet teeth 52, thereby solving the limiting effect on the operation member 12 in the opening direction.

[0046] The movable component 44 includes a pressing member 45 and an elastic member 46. The pressing member 45 is movably mounted on the base 10. A pawl 50 is disposed on the pressing member 45 to move relative to the base 10 along with the pressing member 45. The elastic member 46 is located between the pressing member 45 and the base 10. Therefore, when the pressing member 45 moves relative to the base 10, the elastic member 46 deforms and generates a spring force for resetting the pressing member 45. The side of the pressing member 45 away from the elastic member 46 is exposed on the circumferential side of the base 10, that is, the side of the pressing member away from the elastic member 46 extends outward circumferentially from the base 10 to form a pressing part for user pressing operation. The pawl 50 is located inside the one-way ratchet 48. When the pressing member 45 is pressed inward, the pressing member 45 drives the pawl 50 to move inward, causing the pawl 50 to disengage from between the two ratchet teeth 52, releasing the one-way limiting effect, allowing the operating member 12 to rotate in the opening direction. When the pressing member 45 moves inward, it squeezes the elastic member 46, compressing the elastic member 46. After releasing the pressing member 45, the pressing member 45 can move outward under the action of the elastic member 46, driving the pawl 50 to move outward, causing the pawl 50 to re-insert between the two adjacent ratchet teeth 52, forming a one-way limiting effect and preventing the operating member 12 from rotating in the opening direction. Optionally, the elastic member 46 is a spring.

[0047] In an alternative example, a mounting hole 47 extends through the main body 30 of the base 10, extending from the receiving cavity 26 to the circumferential side of the main body 30. A thickened portion 49 is provided on the side of the cover plate 32 facing the operating member 12, and a receiving groove 51 is provided on the thickened portion 49, which is opposite to and communicates with the mounting hole 47. A pressing member 45 is slidably mounted to the mounting hole 47, with one end extending to the circumferential outer side of the main body 30 to form a pressing portion, and the other end passing through the mounting hole 47 and inserted into the receiving groove 51 on the thickened portion 49. An elastic member 46 is located within the receiving groove 51, and both ends of the elastic member 46 are connected to the thickened portion 49 and the pressing member 45, respectively. When the user presses the pressing member 45, the pressing member 45 slides into the receiving groove 51 and squeezes the elastic member 46. After the user releases the pressing member 45, the pressing member 45 slides out of the receiving groove 51 under the elastic force of the elastic member 46.

[0048] There are two movable components 44 and two pawls 50, each corresponding to the other. The two movable components 44 are located on opposite sides of the base 10, and each movable component 44 has a pawl 50 on its pressing part 45. When the one-way ratchet 48 and the pawl 50 form a one-way limiting effect, each pawl 50 is inserted between two adjacent ratchet teeth 52. When the one-way limiting effect is released, both pawls 50 need to be disengaged from between the ratchet teeth 52, reducing the risk of the clamping arm 14 releasing the electronic device due to accidental pressing of the pressing part 45. At the same time, since the two movable components 44 are located on opposite sides of the base 10, when the one-way limiting effect is released, two fingers can be placed on opposite sides of the base 10 to press the two pressing parts 45, which is convenient for user operation.

[0049] In one embodiment, the bracket 100 further includes a reset member 56, which is located within the receiving cavity 26, and its two ends are connected to the clamping arm 14 and the base 10, respectively. When the operating member 12 rotates in the clamping direction and drives the clamping arm 14 to move through the transmission structure 16, the reset member 56 deforms under the action of the clamping arm 14 and generates elastic force. When the one-way ratchet 48 and the pawl 50 release the one-way limiting effect, the clamping arm 14 can move in the opposite direction under the elastic force of the reset member 56, thereby moving the two clamping arms 14 away from each other to release the electronic device. By setting the reset member 56 between the clamping arm and the base 10, the user only needs to press the pressing member 45 to disengage the pawl 50 from between the adjacent ratchet teeth 52, and the two clamping arms 14 can automatically move away from each other under the action of the reset member 56 to release the electronic device, without the user needing to manually rotate the operating member 12 to release the electronic device, making it convenient for the user.

[0050] Optionally, the reset element 56 is a spring, one end of which is connected to the rack 20, that is, indirectly connected to the clamping arm 14 through the rack 20, and the other end is connected to the cover plate 32 of the base 10. When the two clamping arms 14 are brought close together, the spring is stretched. A hook is provided on the side of the rack 20 away from the gear 18, and one end of the spring is hung on the hook. A mounting post is provided on the cover plate 32, and the other end of the spring is hung on the mounting post.

[0051] In an optional example, both clamping arms 14 are movably connected to the base 10. Each clamping arm 14 is provided with a reset member 56 between it and the base 10. When the two clamping arms 14 move toward each other under the drive of the operating member 12, the reset member 56 deforms and generates elastic force. After pressing the locking member 44 to switch the locking structure 46 to the unlocked state, the two clamping arms 14 move away from each other under the drive of the reset member 56.

[0052] In one embodiment, the bracket 100 further includes a magnetic suction element (not shown). The magnetic suction element is ring-shaped and arranged along the periphery of the base 10. The side of the magnetic suction element facing the clamping space 23 can be used to magnetically engage with electronic devices clamped by the bracket 100 to further enhance the fixing effect between the bracket 100 and the electronic devices. The side of the magnetic suction element away from the clamping space 23 can be used to magnetically engage with external components such as refrigerators, metal window frames, and metal mirror frames to form a wall-mounted effect, thereby fixing the electronic devices on the vertical support surface.

[0053] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
