Adsorption assembly and support

Abstract

This application relates to the field of support technology, and more particularly to an adsorption component and support. The adsorption component includes a housing and an adsorption element. The housing includes an abutment wall and a first rib. The adsorption element includes a connecting portion and an abutment portion. The first rib protrudes towards the adsorption element relative to the abutment wall. When the adsorption component is in the adsorption state, the abutment portion is attached to the abutment wall on the side facing the housing and abuts against the first rib. Since the abutment portion is located in the edge area of ​​the adsorption element, and the first rib protrudes towards the abutment portion, the abutment portion is pressed between the abutment wall and a preset position when the adsorption component is in the adsorption state. Under the abutment of the first rib, the surfaces of the abutment portion and the preset position are tightly fitted, making it difficult for external air to enter between the adsorption element and the preset position from the edge of the adsorption element. The adsorption of the adsorption component and the preset position is more stable, and the adsorption component is less likely to fall off, thus improving the reliability of the adsorption component.

Description

Technical Field

[0001] This application relates to the field of stent technology, and in particular to an adsorption component and stent. Background Technology

[0002] Currently, the adsorption effect of adsorption products on the market can fix the adsorption product in a preset position. After the item (mobile phone, tablet, etc.) is placed on the adsorption product, the item can be firmly fixed in the preset position. Adsorption products usually include a suction cup. After the air between the suction cup and the preset position is expelled, the suction cup can be attached to the surface of the preset position. Under the action of atmospheric pressure, the suction cup is fixed in the preset position.

[0003] However, the adhesion between the suction cup and the preset position is not stable, and it is easy to fall off, resulting in poor reliability of the adsorption product. Utility Model Content

[0004] In a first aspect, embodiments of this application propose an adsorption assembly, which includes a housing and an adsorption element. The housing includes an abutment wall and a first rib. The adsorption element includes a connecting portion and an abutment portion. The connecting portion is connected to the abutment wall, and the abutment portion surrounds the periphery of the connecting portion. The first rib protrudes toward the adsorption element relative to the abutment wall. The adsorption component has an adsorption state and a depressurization state. When the adsorption component is in the depressurization state, there is a gap between the abutting part and the abutting wall. When the adsorption component is in the adsorption state, the abutting part is attached to the abutting wall and abuts against the first rib. Compared with the prior art, the beneficial effects of the adsorption component in the first aspect embodiment of this application are: When the adsorption assembly is in the depressurized state, there is a gap between the abutting part and the abutting wall. When the adsorption assembly is in the adsorption state, the air inside the adsorption element is discharged, the adsorption side of the adsorption element is attached to the surface of the preset position, the abutting part is attached to the abutting wall on the side facing the housing, and abuts against the first rib. Since the abutting part is located in the edge area of ​​the adsorption element, and the first rib on the housing protrudes towards the abutting part, the abutting part is pressed between the abutting wall and the preset position when the adsorption assembly is in the adsorption state. Under the supporting action of the first rib, the abutting part and the surface of the preset position are tightly attached, and external air is not easy to enter between the adsorption element and the preset position from the edge of the adsorption element. The adsorption of the adsorption assembly and the preset position is more stable, the adsorption assembly is not easy to fall off, and the reliability of the adsorption assembly is improved.

[0005] Secondly, an embodiment of this application proposes a support, which includes the adsorption component in the first aspect embodiment and a fixing element connected to the housing for fixing the object to be fixed.

[0006] The bracket in the second aspect embodiment of this application has the beneficial effects of the adsorption component in the first aspect embodiment, which will not be repeated here. In addition, by setting a fixing element in the bracket, the object can be fixed in a preset position after being fixed to the fixing element. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0014] Adsorption products use adsorption to hold items (such as phones and tablets) in place in a preset location. These products typically include a suction cup. After air is expelled from between the suction cup and the preset location, the suction cup adheres to the surface and is held in place by atmospheric pressure. However, factors such as the flatness of the surface, the degree of deformation of the suction cup, and accidental contact with the surface can prevent the suction cup from adhering tightly to the surface. This results in unstable adhesion, allowing air to easily enter between the suction cup and the preset location, causing the product to fall off and leading to poor reliability.

[0015] In view of this, an adsorption component 10 is provided in the embodiments of this application to make the adsorption component 10 adhere tightly to a preset position and improve the reliability of the adsorption component 10; the preset position is not limited to the adsorption position provided by a movable product such as a vehicle, or a product whose position can be fixed such as a table.

[0016] Reference Figures 1 to 4 The adsorption assembly 10 includes a housing 100 and an adsorption member 200. The housing 100 can install and fix the adsorption member 200. The adsorption side of the adsorption member 200 (the side of the adsorption member 200 facing away from the housing 100) is used to adhere to a preset position. The adsorption member 200 is configured as a flexible structure, capable of deforming under external force and returning to its original shape after the external force is removed. The housing 100 includes an abutment wall 110, and the adsorption member 200 includes a connecting portion 210. The connecting portion 210 is connected to the abutment wall 110. The connection method between the connecting portion 210 and the abutment portion 220 is not limited to adhesive bonding, snap-fitting, or integral connection; see reference. Figure 5 and Figure 6 The housing 100 also includes a first rib 120, which is connected to the abutment wall 110 and protrudes toward the adsorption member 200 relative to the abutment wall 110. The adsorption member 200 also includes an abutment portion 220, which surrounds the periphery of the connecting portion 210, such that the abutment portion 220 is located at the outer edge of the connecting portion 210.

[0017] The adsorption component 10 has a pressure relief state and an adsorption state. When the adsorption component 10 is in the pressure relief state (e.g., Figure 3 and Figure 5 As shown), the adsorption member 200 did not deform, and there was a gap between the abutting part 220 and the abutting wall 110; when the adsorption assembly 10 is in the adsorption state (e.g. Figure 4 and Figure 6 As shown), the air inside the adsorption member 200 is discharged, the adsorption member 200 deforms, the adsorption side of the adsorption member 200 is attached to the surface of the preset position, the abutment part 220 is attached to the abutment wall 110 on the side facing the housing 100, and abuts against the first rib 120.

[0018] Since the abutment portion 220 is located in the edge area of ​​the adsorption member 200, and the first rib 120 on the housing 100 protrudes toward the abutment portion 220, the abutment portion 220 abuts against the first rib 120, so that the abutment portion 220 is pressed between the abutment wall 110 and the preset position when the adsorption assembly 10 is in the adsorption state. Under the abutment action of the first rib 120, the surface of the abutment portion 220 and the preset position are tightly attached, and external air is not easy to enter between the adsorption member 200 and the preset position from the edge of the adsorption member 200. The adsorption of the adsorption assembly 10 and the preset position is more stable, and the adsorption assembly 10 is not easy to fall off, thus improving the reliability of the adsorption assembly 10.

[0019] Understandably, when the adsorption assembly 10 is in a depressurized state, the side of the adsorption element 200 facing away from the housing 100 forms an adsorption cavity 230. When the adsorption assembly 10 switches from a depressurized state to an adsorption state, the gas in the adsorption cavity 230 is gradually discharged. When the adsorption assembly 10 switches to the adsorption state, the gas in the adsorption cavity 230 is completely discharged, and at the same time, the adsorption side of the adsorption element 200 is completely attached to the surface at the preset position. The arrangement of the gas in the adsorption cavity 230 is not limited to manual or electric methods. This application takes the electric method as an example, referring to... Figure 3 and Figure 7 The adsorption assembly 10 also includes a vacuum mechanism 300. The adsorption element 200 also has a suction port 240 communicating with the adsorption chamber 230. The adsorption chamber 230 has an opening on the side facing away from the housing 100, so that the adsorption chamber 230 is in an open state. When the adsorption side of the adsorption element 200 contacts the preset position, the opening is blocked by the surface of the adsorption position, and the adsorption chamber 230 is in a closed state. When the adsorption assembly 10 switches from the depressurization state to the adsorption state, the vacuum mechanism 300 extracts the gas in the adsorption chamber 230 through the suction port 240, so that the gas in the adsorption chamber 230 is discharged. The vacuum degree in the adsorption chamber 230 gradually increases. During this process, the adsorption element 200 deforms and gradually approaches the surface of the preset position.

[0020] The first rib 120 extends circumferentially along the abutment wall 110 and is ring-shaped, so as to provide pressure to the abutment portion 220 in the entire circumferential direction, so that any area around the adsorbent 200 is pressed by the first rib 120 and maintains a stable adsorption with the preset position surface. Multiple first ribs 120 can be provided, and adjacent first ribs 120 are arranged to surround each other, that is, in two adjacent first ribs 120, one first rib 120 surrounds the outer periphery of the other first rib 120 and is spaced apart from each other. This can increase the area of ​​the abutment portion 220 pressed by the housing 100, and further improve the stability of the adsorption of the adsorbent 200 with the preset position.

[0021] In one embodiment, reference is made to Figure 5 and Figure 6The adsorption component 200 also includes a second rib 250, which is located on the side of the abutment portion 220 facing the abutment wall 110 and at the edge of the abutment portion 220. The second rib 250 protrudes towards the abutment portion 220. When the adsorption component 10 is in the adsorption state, the second rib 250 abuts against the abutment wall 110. Since the second rib 250 is located at the edge of the adsorption component 200, the abutment wall 110 presses the adsorption component 200 tightly through the abutment of the second rib 250 against the abutment wall 110. The edge area of ​​the adsorption component 200 is closed and in close contact with the preset position, which can prevent external gas from entering between the preset positions of the adsorption component 200, so that the adsorption component 200 can be more stably adsorbed at the preset position.

[0022] It should be noted that the contact position between the first rib 120 and the abutting wall 110 is located outside the contact position between the second rib 250 and the abutting part 220. Thus, along the radial direction of the adsorption member 200, there are multiple pressing positions distributed between the adsorption member 200 and the abutting wall 110, which strengthens the pressing degree of the abutting wall 110 on the adsorption member 200 and can further improve the stability of the adsorption between the adsorption member 200 and the preset position.

[0023] like Figure 7 In the embodiment shown, the abutment portion 220 includes a side wall 221 and a bottom wall 222. The side wall 221 surrounds the outer periphery of the connecting portion 210, and the bottom wall 222 surrounds the outer periphery of the side wall 221. When the adsorption assembly 10 is in a depressurized state, the side wall 221 protrudes from the housing 100 relative to the bottom wall 222, and the bottom wall 222 protrudes from the adsorption cavity 230 relative to the side wall 221. The connecting portion 210 and the side wall 221 together form the adsorption cavity 230. When the adsorption assembly 10 is in an adsorption state, the first rib 120 abuts against the bottom wall 222, and the side wall 221 abuts against the abutment wall 110.

[0024] By providing a bottom wall 222 on the outer periphery of the side wall 221, when the adsorption member 200 begins to contact the preset position, the bottom wall 222 can abut against the surface of the preset position, so that the adsorption member 200 can have a certain contact area with the preset position even in the depressurized state. The bottom wall 222 can cooperate with the surface of the preset position to make the adsorption chamber 230 a sealed state, which can improve the air extraction efficiency of the adsorption chamber 230. In addition, when the adsorption assembly 10 switches to the adsorption state, the adsorption member 200 deforms so that the connecting part 210, the side wall 221 and the bottom wall 222 all contact the surface of the preset position. The contact area between the adsorption member 200 and the preset position is large, which can improve the stability of the adsorption between the adsorption member 200 and the preset position.

[0025] Understandably, the extension direction of the bottom wall 222 is parallel to the extension direction of the connecting portion 210. On the one hand, this reduces the deformation of the bottom wall 222 during the state switching process of the adsorption assembly 10, making the bottom wall 222 flatter. On the other hand, it facilitates direct contact between the bottom wall 222 and the surface at the preset position, which is beneficial for sealing the adsorption cavity 230. The cross-sectional area of ​​the side wall 221 in the direction perpendicular to the depth of the adsorption cavity 230 gradually decreases in the direction toward the housing 100, so that the side wall 221 is inclined relative to the connecting portion 210. This allows the side wall 221 to deform during the switching process of the adsorption assembly 10 to the adsorption state, and keeps the side wall 221 flat after the adsorption assembly 10 switches to the adsorption state, reducing uneven thickness or wrinkles caused by deformation.

[0026] Furthermore, when the adsorption component 10 is in the adsorption state, the thickness of the connecting part 210 protruding from the abutting wall 110, the thickness of the side wall 221, and the thickness of the bottom wall 222 are the same, so that the compression caused by the deformation of the connecting part 210, the side wall 221, and the bottom wall 222 during the switching of the adsorption component 10 to the adsorption state tends to be consistent. After the adsorption component 10 switches to the adsorption state, the thickness of the adsorption member 200 is uniform at all points, the adsorption member 200 is more flat, and the adsorption side of the adsorption member 200 presents as a whole plane, so that the adsorption member 200 can be stably adsorbed and positioned at the preset position.

[0027] It should be noted that the thicknesses of the top wall, side wall 221, and bottom wall 222 all refer to the dimensions perpendicular to their own extension direction. Taking the bottom wall 222 as an example, the bottom wall 222 extends in a direction parallel to the abutting wall 110, so the thickness of the bottom wall 222 is the dimension perpendicular to the abutting wall 110. Taking the side wall 221 as an example, the extension direction of the side wall 221 is inclined relative to the abutting wall 110 and forms a slope, so the thickness of the side wall 221 is the dimension perpendicular to the slope direction.

[0028] In some embodiments, the abutment wall 110 has a recessed groove on the side facing the adsorption member 200, a portion of the connecting portion 210 is embedded in the groove, and a portion of the connecting portion 210 protrudes to the outside of the groove, so that the connecting portion 210 has a certain thickness, and it is beneficial to make the plane of the connecting portion 210 facing the adsorption cavity 230 have a high flatness. The adsorption side of the adsorption member 200 is relatively flat in the adsorption state, and can be stably attached to the surface of the preset position.

[0029] The adsorption assembly 10 also includes an adhesive layer 400, which may include a colloid and has adhesive force. The adhesive layer 400 is disposed on the side of the bottom wall 222 facing away from the housing 100. When the adsorption member 200 begins to contact the preset position, the adhesive layer 400 adheres to the surface of the preset position. On the one hand, the adhesive layer 400 can cooperate with the preset position to seal the opening of the adsorption chamber 230, keeping the adsorption chamber 230 in a sealed state and improving the air extraction efficiency of the adsorption chamber 230. On the other hand, by increasing the adhesive force between the adhesive layer 400 and the preset position, the connection between the adsorption member 200 and the preset position is more stable.

[0030] In one embodiment, reference is made to Figure 3 The adsorption component 200 in this application also includes at least two air channels 260. The air channels 260 are recessed into the wall of the adsorption chamber 230, and each air channel 260 communicates with a suction port 240. The air channels 260 are distributed from the center of the wall of the adsorption chamber 230 to the edge of the wall, ensuring that air channels 260 are evenly distributed throughout the adsorption chamber 230. When the vacuum mechanism 300 extracts gas from the adsorption chamber 230, the gas flows along the air channels 260 and eventually converges at the suction port 240, where it is then extracted by the vacuum mechanism 300. By providing the air channels 260, gas in all areas of the adsorption chamber 230 can flow towards the suction port 240, resulting in cleaner and more thorough extraction of gas from the adsorption chamber 230. This improves the vacuum level of the adsorption chamber 230 when the adsorption component 10 is in the adsorption state, making the adsorption of the adsorption component 200 at the preset position more stable.

[0031] It should be noted that, since the adsorption component 200 is a flexible structure, during the process of switching the adsorption assembly 10 from the depressurization state to the adsorption state, as the gas in the adsorption chamber 230 is gradually discharged, the adsorption component 200 deforms, and the cavity wall of the adsorption chamber 230 and the inner wall of the air passage 260 gradually come into contact with the surface of the preset position until they are completely in contact with the preset position.

[0032] The airway 260 is not limited to being configured as a ring, straight line, curved line, or zigzag line. For example... Figure 8 In the illustrated embodiment, the radial direction of the adsorbent 200 is defined as the direction from the center of the adsorbent 200 to its edge. The air passages 260 are arranged radially, and different air passages 260 are spaced apart circumferentially around the adsorbent 200. This ensures that the air passages 260 are evenly distributed both circumferentially and radially around the adsorbent 200. Therefore, when the vacuum mechanism 300 extracts gas from the adsorption chamber 230, gas in each region of the adsorption chamber 230 can flow along the air passages 260 to the extraction port 240 and be extracted, allowing each region of the adsorbent 200 to be stably attached to a preset position. Furthermore, in addition to extending radially along the adsorbent 200, the air passages 260 can also be configured as curves or broken lines to further expand the distribution area of ​​the air passages 260.

[0033] Or, such as Figure 9 In the illustrated embodiment, the air passages 260 extend circumferentially along the adsorption member 200 and are annular. Among adjacent air passages 260, one air passage 260 surrounds the outer periphery of another air passage 260, and the air passages 260 are arranged at radial intervals along the adsorption member 200. Thus, the adsorption member 200 is evenly distributed with air passages 260 in both the circumferential and radial directions. When the vacuum mechanism 300 extracts gas from the adsorption chamber 230, the gas in each area of ​​the adsorption chamber 230 can flow along the air passages 260 to the extraction port 240 and be extracted, and each area of ​​the adsorption member 200 can be stably attached to the preset position. Furthermore, based on the annular shape of the air passages 260, the air passages 260 can also be set as curved or broken lines to further diffuse the distribution area of ​​the air passages 260.

[0034] Or, such as Figure 7 In the illustrated embodiment, the air passage 260 includes an inner ring air passage 261, an outer ring air passage 262, and a diverging air passage 263. The diverging air passage 263 extends radially along the adsorption member 200. The inner ring air passage 261 and the outer ring air passage 262 extend circumferentially along the adsorption member 200 and are annular. The inner ring air passage 261 and the outer ring air passage 262 are connected through the diverging air passage 263. At least two diverging air passages 263 are provided and are arranged at intervals along the circumferential direction of the adsorption member 200. One end of the diverging air passage 263 facing the edge of the adsorption member 200 is connected to the outer ring air passage 262, and the diverging air passage 263 facing the center of the adsorption member 200 is connected to the inner ring air passage 261. Each air passage 260 is distributed in the edge region, the central region, and the area between the two of the adsorption cavity 230. When the vacuum mechanism 300 extracts the gas in the adsorption cavity 230, the gas in the edge region of the adsorption cavity 230 enters the outer ring air passage 262 and then enters the diverging air passage 263. The gas between the edge region and the central region simultaneously enters the diverging air passage 263 and flows to the inner ring air passage 261. The gas in the central region of the adsorption cavity 230 simultaneously enters the inner ring air passage 261 and is then discharged from the adsorption cavity 230 through the extraction hole 240, so that the gas in each region of the adsorption cavity 230 is extracted and the adsorption element 200 can be stably adsorbed at the preset position.

[0035] It should be noted that the adsorption member 200 may be provided with at least two inner ring air channels 261 distributed radially along the adsorption member 200 and at least two outer ring air channels 262 distributed radially along the adsorption member 200 to expand the distribution range of the air channels 260. In addition, the suction hole 240 extends along the thickness direction of the adsorption member 200. One end of the suction hole 240 is connected to the inner ring air channel 261, and the other end is connected to the vacuum mechanism 300 through a pipeline. The inner ring air channel 261 is located at the center of the adsorption cavity 230. The diverging air channels 263 converge towards the inner ring air channel 261, so that the gas flowing from the diverging air channel 263 to the inner ring air channel 261 has a tendency to converge and can be quickly drawn away through the suction hole 240.

[0036] Furthermore, in the case where the connecting portion 210 and the sidewall 221 jointly define the adsorption cavity 230, the extraction port 240 can be provided in the connecting portion 210, so that the extraction port 240 can take into account the convergence of gas in different areas of the adsorption cavity 230, thereby improving the extraction efficiency of the adsorption assembly 10. Specifically, the maximum distance between the extraction port 240 and the center of the connecting portion 210 is less than the minimum distance between the extraction port 240 and the edge of the connecting portion 210, so that the extraction port 240 is maximized to be close to the center of the adsorption cavity 230, so that the gas in each area of ​​the adsorption cavity 230 can converge to the extraction port 240.

[0037] In one embodiment, reference is made to Figure 3 and Figure 4 The vacuum mechanism 300 includes a trigger button 310 and a power element 320. The power element 320 can adsorb gas in the adsorption chamber 230 through the suction port 240, causing the adsorption member 200 to deform under external air pressure. The power element 320 is not limited to being a suction component such as an air pump. In some embodiments, the vacuum mechanism 300 also includes an energy storage component, such as a battery. The energy storage component can be charged and discharged. The energy storage component is electrically connected to the power element 320 and is used to supply power to the power element 320. The vacuum mechanism 300 also includes a circuit board 330. Both the circuit board 330 and the power element 320 can be disposed inside the housing 100. The circuit board 330 integrates control circuitry and is electrically connected to the power element 320, and is used to start or stop the power element 320 from suctioning. It should be noted that the control circuitry on the circuit board 330 and the method of switching the start / stop state of the power element 320 are prior art and will not be described in detail here.

[0038] Reference Figure 7The adsorption component 200 also has a moving channel 270, which communicates with the adsorption chamber 230. The trigger button 310 is movably disposed within the moving channel 270 and can enter and exit the adsorption chamber 230. When it is necessary to fix the adsorption component 10 in a preset position, the operator holds the adsorption component 10 so that the adsorption side of the adsorption component 200 contacts the preset position, the adsorption chamber 230 is closed, and then presses the adsorption component 10 toward the preset position, so that the adsorption component 10 switches from the depressurization state to the adsorption state. When the trigger part contacts the preset position, the trigger part moves along the moving channel 270 toward the housing 100 under the resistance of the preset position, so that the power element 320 is triggered. The power element 320 draws gas from the adsorption chamber 230 through the air extraction hole 240 until the adsorption component 10 switches to the adsorption state.

[0039] The moving channel 270 extends through the adsorption element 200 along its thickness direction and is positioned at the center of the adsorption element 200, allowing the bottom wall 222 of the adsorption element 200 to uniformly contact the preset position, facilitating the sealing of the adsorption chamber 230. An inner ring air passage 261 surrounds the moving channel 270, and an extraction port 240 communicates with the inner ring air passage 261, maximizing the proximity of the inner ring air passage 261 and the extraction port 240 to the center of the adsorption chamber 230. This promotes gas convergence within the adsorption chamber 230 and improves extraction efficiency.

[0040] In addition, the connecting part 210 is also provided with a connecting hole 280. The suction hole 240 and the connecting hole 280 are arranged along the thickness direction of the connecting part 210. One end of the suction hole 240 is connected to the connecting hole 280, and the other end is connected to the power element 320 through a pipe. The end of the connecting hole 280 facing away from the suction hole 240 is connected to the air passage 260. The airflow flowing through the air passage 260 enters the suction hole 240 through the connecting hole 280. The diameter of the connecting hole 280 is larger than the diameter of the suction hole 240. On the one hand, the connecting holes 280 have a larger distribution range, which facilitates the connection between each air passage 260 and the connecting hole 280. On the other hand, the connecting hole 280 guides the gas in the air passage 260 to flow towards the suction hole 240, which is beneficial for the gas to converge towards the suction hole 240. Understandably, the connecting hole 280 can be set as circular (e.g., Figure 7 and Figure 9 As shown), ring (as shown) Figure 8 (as shown) and other shapes.

[0041] It should be noted that the connecting hole 280 is connected to the diverging airway 263, and / or to the inner ring airway 261, such as... Figure 7In the illustrated embodiment, some of the diverging air channels 263 are connected to the connecting hole 280, and the inner ring air channel 261 can also be connected to the connecting hole 280, so that the gas in the inner ring air channel 261 and the diverging air channel 263 can directly enter the connecting hole 280, and the gas in multiple air channels 260 can directly enter the exhaust hole 240 through the connecting hole 280, thereby improving the adsorption efficiency of the adsorption component 10.

[0042] In some embodiments, reference is made to Figure 3 The adsorption component 10 also includes breathable cotton 500, which is filled in the connecting hole 280. The breathable cotton 500 allows gas to pass through and blocks impurities, thereby improving the airtightness of the extraction hole 240. This prevents external impurities from entering or blocking the extraction hole 240, or from being sucked into the extraction hole 240 by the vacuum mechanism 300, and then entering the power element 320, affecting the service life of the adsorption component 10.

[0043] The embodiments of this application also provide a bracket, which is used to fix the object to be fixed in a preset position, see reference. Figure 10 The bracket includes the aforementioned adsorption component 10 and also includes a fixing element 20. The fixing element 20 is connected to the housing 100 and is used to fix the object to be fixed.

[0044] In some embodiments, the fixing element 20 is a magnet, which may be built into the housing 100, and the object to be fixed can be fixed by the magnet through magnetic attraction. In some embodiments, the fixing element 20 is a clamping component, which is connected to the side of the housing 100 facing away from the adsorption component 200, and can clamp the object to be fixed. The bracket may also include a support arm 30, with its two ends connected to the adsorption component 10 and the fixing element 20 respectively, and the support arm 30 is used to change the distance and / or relative angle between the adsorption component 10 and the fixing element 20.

[0045] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
