[0060] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0061] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0062] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0063] This disclosure provides an assembly fixture for assembling two components to be assembled. For example, the two components are a light strip 10 and a light guide plate 20. Of course, the two components can also be other components to be assembled, and this disclosure does not limit this.

[0064] like Figure 1 As shown, the light strip 10 typically includes a flexible circuit board 110 and multiple light-emitting units 120 (LEDs) bonded to one side of the flexible circuit board 110. The multiple light-emitting units 120 are arranged in a row, and the light-emitting side of each light-emitting unit 120 is parallel to the plane on which the flexible circuit board 110 is located, that is, the multiple light-emitting units 120 emit light in the same direction.

[0065] Among them, such as Figure 1 As shown, the flexible circuit board 110 has a circuit connector 130, and multiple light-emitting units 120 bound to the flexible circuit board 110 are used to electrically connect to an external circuit through the circuit connector 130. An adhesive is applied to one side of the flexible circuit board 110 where the light-emitting units 120 are bound, so that the light guide plate 20 can be bonded to the flexible circuit board 110, thus assembling the light strip 10 and the light guide plate 20.

[0066] like Figure 2 As shown, the assembly fixture includes: a support platform 1, an adsorption component 2, a guide rail 3, and a pressing component 4. The support platform 1 has a support area 101, a first limiting surface 102 and a second limiting surface 103, and a plurality of adsorption holes 104 penetrating the support area 101. The first limiting surface 102 is located on one side of the support area 101 along the first direction O1, and the second limiting surface 103 is located on one side of the support area 101 along the second direction O2. The first direction O1 and the second direction O2 intersect. The adsorption component 2 communicates with the plurality of adsorption holes 104 and is used to form a negative pressure in the adsorption holes 104. The guide rail 3 is limited on the support platform 1 and is located on one side of the support area 101. The length direction of the guide rail 3 is parallel to the second direction O2. The pressing component 4 is slidably limited on the guide rail 3. The pressing component 4 has a pressing surface facing the support area 101. When the pressing component 4 slides, the orthographic projection of the pressing surface on the support platform 1 is located in the support area, and there is a gap between the pressing surface and the surface of the support area 101.

[0067] In this embodiment, the first component to be assembled, placed in the bearing area 101, can be positioned using the first limiting surface 102 and the second limiting surface 103, thus simplifying the positioning operation and improving positioning efficiency. The positioned first component is then fixed by the adsorption component 2 to ensure stability and prevent component displacement. After the second component to be assembled is placed on top of the first component, the pressing component 4 slides along the guide rail 3, pressing the first and second components together using the pressing surface of the pressing component 4, thus assembling the two components. In this way, the assembly fixture improves assembly efficiency while ensuring the yield of the assembled product.

[0068] The bearing area 101 refers to the common area of ​​the first region located on one side of the first limiting surface 102 and the second region located on one side of the second limiting surface 103. Thus, part of the outline of the outer contour of the bearing area 101 is located within the first limiting surface 102, and part of the outline is located within the second limiting surface 103.

[0069] The surface of the bearing area 101, the first limiting surface 102, and the second limiting surface 103 are all planes (not limited to planes in the strict sense). The first limiting surface 102 and the second limiting surface 103 are perpendicular to the surface of the bearing area 101. Of course, the angle between the first limiting surface 102, the second limiting surface 103 and the surface of the bearing area 101 can be slightly less than 90 degrees or slightly greater than 90 degrees. This disclosure does not limit this.

[0070] The first direction O1 and the second direction O2 are both parallel to the surface of the bearing area 101, and the first direction O1 is perpendicular to the first limiting surface 102, while the second direction O2 is perpendicular to the second limiting surface 103.

[0071] The first direction O1 is perpendicular to the second direction O2. Thus, the first limiting surface 102 is perpendicular to the second limiting surface 103, thereby facilitating the positioning of components with right-angled corners via the first limiting surface 102 and the second limiting surface 103. Of course, the angle between the first direction O1 and the second direction O2 can be slightly less than 90 degrees or slightly greater than 90 degrees, as long as the first limiting surface 102 and the second limiting surface 103 can be used to position the first component supported by the bearing area 101. This embodiment does not limit this.

[0072] The cross-section of the guide rail 3 can be circular, elliptical, or rectangular, etc. When the cross-section of the guide rail 3 is circular, the assembly fixture includes multiple parallel guide rails 3. The plane containing the multiple guide rails 3 is parallel to the surface of the bearing area 101 to avoid rotation of the pressing assembly 4. For example, as shown... Figure 2As shown, the cross-section of the guide rail 3 is circular, and the assembly fixture includes two parallel guide rails 3. The guide rail 3 is directly limited on the support platform 1, or the support platform 1 is provided with a support seat 105 on one side of the support area 101, and the guide rail 3 is limited on the support seat 105. This embodiment does not limit the specific method described herein.

[0073] In practical use, taking the assembly of light strip 10 and light guide plate 20 as an example, light strip 10 is placed in the support area 101 of the support platform 1, that is, the support area 101 is used to support light strip 10. The two adjacent sides of light strip 10 are limited by the first limiting surface 102 and the second limiting surface 103 to achieve the positioning of light strip 10. Then, the positioned light strip 10 is fixed by the adsorption component 2 to ensure the stability of the fixation and the flatness of light strip 10 itself, while avoiding the occurrence of displacement or bending of light strip 10. Then, light guide plate 20 is covered on the flexible circuit board 110 included in light strip 10, and pressing component 4 is slid along guide rail 3 to press light guide plate 20 and light strip 10 together to achieve the assembly of light strip 10 and light guide plate 20. In this way, the assembly fixture can improve the assembly efficiency of light strip 10 and light guide plate 20, while ensuring the yield of the assembled product.

[0074] In conjunction with the structure of the light strip 10, since the flexible circuit board 110 included in the light strip 10 has a circuit connector 130, the circuit connector 130 usually protrudes from the edge of the flexible circuit board 110. Thus, in order to facilitate the first limiting surface 102 to limit the light strip 10, for example, the first limiting surface 102 includes a first sub-limiting surface and a second sub-limiting surface that are spaced apart. In this way, when limiting the light strip 10, the circuit connector 130 can pass through the gap between the first sub-limiting surface and the second sub-limiting surface, so as to avoid the circuit connector 130 obstructing the limiting of the light strip 10.

[0075] When the light guide plate 20 is covered on the light strip 10, in combination with the structure of the light strip 10, the light guide plate 20 can be limited along the first direction O1 by multiple light-emitting units 120. If the side of the light strip 10 with the light-emitting unit 120 is limited by the first limiting surface 102, the light guide plate 20 is limited along the second direction O2 by the second limiting surface 103, so as to ensure the accuracy of the alignment between the light strip 10 and the light guide plate 20, and at the same time ensure that there is no gap between the light strip 10 and the light guide plate 20.

[0076] It should be noted that the height of the second limiting surface 103 is equal to the sum of the thickness of the light guide plate 20 and the thickness of the flexible circuit board 110 included in the light strip 10. Of course, the height of the second limiting surface 103 can also be slightly less than the sum of the thickness of the light guide plate 20 and the thickness of the flexible circuit board 110 included in the light strip 10, or greater than the sum of the thickness of the light guide plate 20 and the thickness of the flexible circuit board 110 included in the light strip 10, as long as the second limiting surface 103 can simultaneously limit the light strip 10 and the light guide plate 20. This embodiment does not limit this.

[0077] When the height of the second limiting surface 103 is greater than the sum of the thickness of the light guide plate 20 and the thickness of the flexible circuit board 110 included in the light strip 10, in order to prevent the pressing component 4 from pressing the light guide plate 20 and the light strip 10 together, the second limiting surface 103 has a notch, the width of which is greater than or equal to the width of the pressing component 4.

[0078] In this embodiment of the disclosure, a first limiting surface 102 and a second limiting surface 103 can be formed through the sidewall of the groove 111. Specifically, as shown... Figure 3 As shown, the platform body 11 has a groove 111 extending to the edge. The groove 111 has a sidewall perpendicular to a first direction O1 and a sidewall perpendicular to a second direction O2. The bottom surface of the groove 111 forms a bearing area 101. The sidewall of the groove 111 perpendicular to the first direction O1 forms a first limiting surface, and the sidewall perpendicular to the second direction O2 forms a second limiting surface. Thus, the positioning of the component to be assembled, which is supported in the bearing area 101, is achieved by the sidewall of the groove 111 perpendicular to the first direction O1 and the sidewall perpendicular to the second direction O2, that is, by the two adjacent sidewalls of the groove 111. The groove 111 can be a rectangular groove with an opening on one side. In this case, the first limiting surface 102 and the second limiting surface 103 formed by the two adjacent sidewalls of the groove 111 are perpendicular, and both the first limiting surface 102 and the second limiting surface 103 are perpendicular to the surface of the bearing area 101.

[0079] It should be noted that, in conjunction with the above description, when the light strip 10 is limited by the two adjacent sidewalls of the groove 111, in order to avoid the circuit connector 130 included in the light strip 10 from causing obstruction, one sidewall of the groove 111 perpendicular to the first direction O1 has a first clearance groove 122; in order to avoid the second limiting surface 103 from obstructing the movement of the pressing assembly 4 when the pressing assembly 4 presses the light guide plate 20 and the light strip 10, the surface of the support platform 1 has a second clearance groove 113 extending along the second direction O2 to the groove 111.

[0080] In this embodiment of the disclosure, in addition to forming the first limiting surface 102 and the second limiting surface 103 through the above-described embodiments, the first limiting surface 102 and the second limiting surface 103 can also be formed by other means.

[0081] For the first limiting surface 102, as Figure 4 As shown, the support platform 1 includes a platform body 11 and a first limiting structure 12; the first limiting structure 12 is limited on one side of the support area 101 along the first direction O1, and the first limiting structure 12 has a first limiting surface 102.

[0082] The first limiting structure 12 can be a strip-shaped structure extending along the second direction O2, thus increasing the limiting area of ​​the first limiting surface 102. In conjunction with the above, when limiting the light strip 10 using the first limiting structure 12, to avoid obstruction by the circuit connector 130 included in the light strip 10, such as... Figure 4 As shown, the first limiting structure 12 has a first clearance groove 122, or the first limiting structure 12 includes a first sub-limiting structure and a second sub-limiting structure that are spaced apart.

[0083] For the second limiting surface 103, the platform body 11 has a groove 111 extending to the edge, the groove 111 having a sidewall perpendicular to the second direction; the bottom surface of the groove 111 forms a bearing area 101, and the sidewall of the groove 111 perpendicular to the second direction forms the second limiting surface 103. Alternatively, the platform 1 may further include a second limiting structure, which is limited on the platform body 11 and located on one side of the bearing area 101 along the first direction, and the second limiting structure has a second limiting surface 103.

[0084] The second limiting structure can be a strip-shaped structure extending along the second direction O2. When the component to be assembled is limited by the groove 111 along a sidewall perpendicular to the second direction O2, or by the second limiting structure, to prevent the sidewall of the groove 111 and the second limiting structure from obstructing the movement of the pressing assembly 4, the surface of the platform body 11 and the second limiting structure have a second clearance groove 113 extending along the second direction O2. For example, in the case of limiting by the sidewall of the groove 111, such as... Figure 4 As shown, the surface of the stage body 11 has a second clearance groove 113 extending along the second direction O2 to the groove 111.

[0085] In this embodiment of the present disclosure, regarding the case where the first limiting structure 12 forms the first limiting surface 102 as described above, when the first limiting structure 102 limits the components to be assembled, in order to facilitate the assembly fixture to bear components of different sizes to be assembled, the position of the first limiting structure 12 along the first direction O1 is adjustable, or the position along the second direction O2 is adjustable, or the position along both the first direction O1 and the second direction O2 is adjustable. Thus, by adjusting the position of the first limiting structure 12, the size of the bearing area 101 can be adjusted, thereby enabling the positioning of components of different sizes to be assembled within the bearing area 101.

[0086] When the position of the first limiting structure 12 is adjustable along the first direction O1, the platform body 11 has a first sliding groove 112 extending along the second direction, and the platform 1 also includes a first limiting rod (not shown in the figure); one end of the first limiting rod passes through the first sliding groove 112 and is limitedly connected to the first limiting structure 12, and the other end of the first limiting rod is detachably limited on the side of the platform body 11 away from the first limiting structure 12.

[0087] The first limiting rod is a headed bolt. The threaded end of the bolt passes through the first sliding groove 112 and is connected to the first limiting structure 12. The bolt is limited by friction with the support platform 1. When the bolt is loosened from the limiting connection of the first limiting structure 12, the bolt can move along the first sliding groove 112, thereby driving the first limiting structure 12 to move synchronously.

[0088] When adjusting the position of the first limiting structure 12, the other end of the detachable first limiting rod is limited on one side of the platform body 11. Then, the first limiting rod slides along the first sliding groove 112, and the first limiting structure 12 slides relative to the first limiting rod along the second sliding groove 121. After completing the position adjustment of the first limiting structure 12, the other end of the first limiting rod is re-limited on one side of the platform body 11. Of course, the above structure can also satisfy the adjustment of the first limiting structure 12 alone along the first direction O1 or alone along the second direction O2. The specific adjustment method can be referred to the above adjustment method, which will not be repeated in this embodiment.

[0089] When the position of the first limiting structure 12 along the second direction O2 is adjustable, the first limiting structure 12 has a second sliding groove 121 extending along the first direction, and the support platform 1 also includes a second limiting rod (not shown in the figure); one end of the second limiting rod passes through the second sliding groove 121 and is limitedly connected to the platform body 11, and the other end of the second limiting rod is detachably limited to the side of the first limiting structure 12 away from the platform body 11.

[0090] The structure of the second limiting rod can refer to the structure of the first limiting rod described above, and the principle of the first limiting structure 12 adjusting its position along the second direction O2 can refer to the principle of the first limiting structure 12 adjusting its position along the second direction O2 described above. This disclosure does not limit this aspect.

[0091] When the position of the first limiting structure 12 is adjustable along both the first direction O1 and the second direction O2, such as Figure 4As shown, the platform body 11 has a first groove 112 extending along the second direction O2, the first limiting structure 12 has a second groove 121 extending along the first direction O1, and the platform 1 also includes a third limiting rod; one end of the third limiting rod passes through the first groove 112 and the second groove 121, and one end of the third limiting rod is detachably limited to the first limiting structure 12, and the other end of the third limiting rod is detachably limited to the platform body 11.

[0092] The structure of the third limiting rod can be referenced to the first limiting rod described above. The principle of position adjustment of the first limiting structure 12 along the first direction O1 and along the second direction O2 can be referenced to the principle of adjustment of the first limiting structure along the first direction O1 described above. This embodiment of the present disclosure does not limit this aspect. For example, the third limiting rod is a double-ended bolt, and the two ends of the third limiting rod are detachably limited to the platform body 11 and the first limiting structure 12 respectively through corresponding nuts.

[0093] In the case where the second limiting surface 103 is formed by the second limiting structure as described above, when the component to be assembled is limited by the second limiting structure, in order to facilitate the bearing area to bear the component to be assembled of different sizes, the position of the second limiting structure in the second direction O2 is adjustable, and / or the position in the first direction O1 is adjustable.

[0094] Thus, by adjusting the position of the second limiting structure, the size of the bearing area can be adjusted, thereby enabling the positioning of components of different sizes to be assembled within the bearing area. For cases where the position of the second limiting structure is adjustable, refer to the description of the position adjustment of the first limiting structure 12 described above; this embodiment will not elaborate further.

[0095] In this embodiment of the present disclosure, the component to be assembled, which is supported in the support area 101, can be fixed by vacuum adsorption, which simplifies the operation, improves the fixing efficiency, and also ensures the flatness of the component to be assembled.

[0096] In some implementations, such as Figure 3 or Figure 4 As shown, the adsorption assembly 2 includes a vacuum generator 21, the suction end of which is connected to multiple adsorption holes 104. Thus, after the component to be assembled is positioned by the first limiting surface 102 and the second limiting surface 103, the vacuum generator 21 can be activated. At this time, the multiple adsorption holes 104 can generate negative pressure to achieve adsorption and fixation of the component to be assembled.

[0097] Among them, such as Figure 3As shown in Figure 4, the adsorption assembly 2 also includes a gas source switch 22. One end of the gas source switch 22 is connected to the air inlet of the vacuum generator 21, and the other end is connected to an air compressor. Thus, when the gas source switch 22 is in the open state, the air compressor can provide high-pressure gas to the air inlet of the vacuum generator 21, so that the suction end of the vacuum generator 21 can draw in gas, thereby starting the vacuum generator 21 and facilitating operation by the operator.

[0098] In some embodiments, the adsorption assembly 2 further includes multiple regulating valves, the first end of which is connected to the suction end of the vacuum generator 21, and the second end of each regulating valve is connected to at least one adsorption hole 104. Thus, the negative pressure of each adsorption hole 104 can be adjusted using multiple regulating valves, thereby preventing excessive negative pressure in individual adsorption holes 104 that could cause wrinkles in the component to be assembled.

[0099] In some implementations, such as Figure 5 As shown, the assembly fixture also includes a base 5, which has multiple air passages 51 corresponding to multiple regulating valves. The base 5 is located on the side of the support platform 1 away from the support area 101 (that is, the support platform 1 is fixed on the base 5, and the support area 101 is located on the side away from the base 5), and each air passage 51 is connected to at least one adsorption hole 104, and each air passage 51 is connected to the second end of the corresponding regulating valve.

[0100] Thus, the air passage 51 provided on the base 5 can connect a regulating valve to at least one adsorption hole 104, thereby simplifying the connection process between at least one adsorption hole 104 and the corresponding regulating valve. For example, a regulating valve can be connected to five adsorption holes 104 through the corresponding air passage 51, thereby avoiding the need to provide five connecting pipes between the regulating valve and the five adsorption holes 104.

[0101] Of course, in this embodiment, the adsorption component 2 may include a vacuum generator 21 or a vacuum suction cup, so as to achieve adsorption and fixation of the light strip 10 through the vacuum suction cup. The vacuum suction cup is fixed in the adsorption hole 104. The specific principle of the vacuum suction cup adsorbing and fixing the component to be assembled can be referred to the relevant technology, and this embodiment does not limit it.

[0102] In some implementations, such as Figure 6 and Figure 7 As shown, the pressing assembly 4 includes a slider 41, a connecting block 42, and a pressing body 43; the slider 41 is slidably limited on the guide rail 3, the connecting block 42 is limited to the slider 41, and the pressing body 43 is limited on the connecting block 42; when the slider 41 slides, the orthographic projection of the pressing body 43 on the support platform 1 is located in the support area 101, and there is a gap between the pressing body 43 and the surface of the support area 101.

[0103] The pressing body 43 can be either a pressing roller or a pressing block. When the pressing body 43 is a pressing roller, the pressing roller is rotatably limited by the connecting block 42. In this way, when the two components to be assembled are pressed together by the pressing roller, the pressing roller can reduce the friction between itself and the components based on its own rotation.

[0104] The pressing rollers are made of non-rigid materials to avoid hard contact when pressing the components to be assembled. For example, the pressing rollers are made of silicone. The pressing assembly 4 includes multiple pressing rollers, which are parallel in axis. In some embodiments, the multiple pressing rollers are distributed along the length direction of the guide rail 3, i.e., the second direction O2, thus ensuring the pressing effect of the pressing rollers on the components to be assembled. In other embodiments, the multiple pressing rollers are distributed along a direction perpendicular to the length direction of the guide rail 3, i.e., the first direction O1, thus increasing the pressing area of ​​the pressing rollers on the components to be assembled. In still other embodiments, the multiple pressing rollers are distributed in a matrix along the first direction O1 and the second direction O2, which not only ensures the pressing effect of the pressing rollers on the components to be assembled but also increases the pressing area of ​​the pressing rollers on the components to be assembled.

[0105] In some embodiments, the distance between the pressing body 43 and the surface of the bearing area 101 is not adjustable, in which case the connecting block 42 and the slider 41 are fixedly connected. For example, such as... Figure 7 As shown, the slider 41 has a limiting hole 411, and at least a portion of the connecting block 42 is limited within the limiting hole 411.

[0106] Among them, the connecting block 42 can be directly connected to the slider 41 for limiting, of course, if Figure 6 or Figure 7 As shown, the pressing component 4 includes a handrail 44, which is fixedly connected to the slider 41. At this time, the connecting block 42 can be limited to the handrail 44, that is, the connecting block 42 extends into the limiting hole 411 and is limited to the handrail 44.

[0107] During the use of this assembly fixture, for components of different thicknesses to be assembled, it is necessary to adjust the gap between the pressing body 43 and the surface of the bearing area 101. This can be achieved by replacing the pressing body 43 with one of different sizes. To facilitate the replacement of the pressing body 43 later, that is, to facilitate the disassembly of the connecting block 42 and the slider 41 or the handrail 44 (the connecting block 42 and the slider 41, or the connecting block 42 and the handrail 44 are detachably fixedly connected), in some embodiments, such as... Figure 6 or Figure 7As shown, the assembly fixture also includes a rotating block 6, a limiting block 7, a buckle 8, and a hook 9; the support platform 1 is provided with a support base 105 on one side of the support area 101, one end of the rotating block 6 is rotatably limited on the support base 105, and the end of the guide rail 3 is fixed on the rotating block 6; the limiting block 7 is fixed on the support platform 1 and is located on the side of the support base 105 close to the support area 101, and the distance between the limiting block 7 and the support base 105 is less than the length of the rotating block 6; the buckle 8 is fixed on the support platform 1, and the hook 9 is fixed on the other end of the rotating block 6. When the rotating block 6 is supported on the limiting block 7, the buckle 8 and the hook 9 are connected.

[0108] Thus, when replacing the pressing body 43, the connection between the buckle 8 and the hook 9 is disassembled, and then the rotating block 6 is rotated to drive the guide rail 3 to rotate synchronously. At this time, the guide rail 3 drives the slider 41 to rotate synchronously, which increases the distance between the pressing body 43 and the support platform 1, thereby facilitating the disassembly of the connecting block 42 and the slider 41 or the handrail 44. After the replacement is completed, the rotating block 6 is rotated in the opposite direction to avoid a small angle between the rotating block 6 and the support platform 1 under the limitation of the limiting block 7, while ensuring that there is a predetermined gap between the pressing body 43 and the surface of the support area 101. Then, the buckle 8 and the hook 9 are engaged to fix the rotating block 6.

[0109] In other embodiments, the distance between the pressing body 43 and the surface of the bearing area 101 is adjustable. Thus, when pressing the components to be assembled, the distance between the pressing body 43 and the surface of the bearing area 101 can be adjusted for components of different thicknesses, thereby facilitating the pressing of components of different thicknesses and improving the applicability of the assembly fixture. Furthermore, by adjusting the distance between the pressing body 43 and the surface of the bearing area 101, the pressing force on the components to be assembled can be adjusted, thereby ensuring the tightness of the pressing of the two components.

[0110] In some embodiments, the pressing assembly 4 further includes an elastic element and a connector; both ends of the connector are threadedly connected to at least one of the slider 41 and the connecting block 42, and the elastic element is clamped between the slider 41 and the connecting block 42.

[0111] The elastic element can be a compression spring, and the connecting element can be a bolt. Thus, the bolt can be loosened to increase the distance between the slider 41 and the connecting block 42, or the bolt can be tightened to decrease the distance between the slider 41 and the connecting block 42. After adjusting the distance between the slider 41 and the connecting block 42, the compression spring can extend or shorten based on its own elastic force to ensure that the relative position of the slider 41 and the connecting block 42 is constant.

[0112] Of course, in this embodiment of the present disclosure, in addition to adjusting the distance between the pressing body 43 and the surface of the bearing area 101 as described above, the distance between the pressing body 43 and the surface of the bearing area 101 can also be adjusted in other ways. For example, when the pressing component 4 includes a handrail, the distance between the connecting block 42 and the handrail 44 is adjustable, thereby realizing the adjustment of the distance between the pressing body 43 and the surface of the bearing area 101. This embodiment of the present disclosure does not limit this.

[0113] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
