Description

Technical Field

[0001] This utility model relates to the field of lifting furniture, and in particular to a universal wiring harness for managing lifting articulated arms. Background Technology

[0002] Most existing office desks have fixed-height desktops. While this design offers advantages such as simple structure and higher stability, it also has significant drawbacks: it doesn't provide adequate comfort or flexibility for users of different heights, and it doesn't allow for standing work. Therefore, new types of office desks with adjustable desktops have emerged in the market.

[0003] However, this leads to a problem: the fixed lengths of various electrical appliance wiring harnesses that were originally sufficient for the needs now require more length to ensure that the harnesses are not pulled or stretched when appliances such as computers and desk lamps are moved to relatively high places along the desktop.

[0004] At this point, a cable management tool is needed to ensure that when the desktop is in a relatively low position, excessively long cables will not hang to the ground or trip your legs. The curved arm assembly is thus created. It is made of hollow tubing and is hinged to the desktop and base of the height-adjustable table. It unfolds or folds as the desktop is raised or lowered, and the cables are hidden and protected in the hollow tubing, thus preventing the cables from being exposed and hanging to the ground or tripping your legs.

[0005] Because a plug needs to be installed at the end of the wire harness, if the wire harness is to be inserted directly through the end opening of the crank arm, the cross-sectional dimension of the crank arm must be larger than the plug, which will increase the material cost of the crank arm. Therefore, the crank arm is often U-shaped and equipped with a removable cover plate. When installing the cover plate, elastic clips are required for the crank arm. Ordinary elastic clips not only protrude obviously and have an awkward appearance, but also require slots to be cut on the side of the crank arm to provide elastic deformation capability. This not only has aesthetic defects, but also reduces its strength due to the slots on the side of the crank arm, which will affect its lifespan. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model provides a universal wire harness management lifting arm, comprising a main body with two spaced side plates forming an opening and a space for accommodating the wire harness. Each side plate has an inwardly protruding buckle and a stop on its inner side. The buckle is located at the opening, with its highest point lower than the highest point of the side plate, and the stop is below the buckle. A detachable cover plate is installed between the buckle and the stop, which closes the opening and confines the wire harness within the accommodating space. This design allows the buckle to be hidden inside the side plate, not protruding, achieving a side-concealing effect and improving the arm's aesthetics. Furthermore, it eliminates the need for slotting on the side plate or its outer surface, maintaining the integrity of the side plate, enhancing the overall strength of the arm, and extending its service life.

[0007] The technical solution of this utility model is implemented as follows: A universal wire harness management lifting arm includes a main body, which includes two spaced-apart side plates. An opening and a receiving space for accommodating wire harnesses are formed between the two side plates. A buckle and a stop are provided on the inner side of each side plate, and both the buckle and the stop protrude inward from the inner side of the side plate. The buckle is located at the opening, and the highest point of the buckle is below the highest point of the side plate. The stop is located below the buckle. A cover plate is detachably provided between the buckle and the stop. The cover plate is configured to be installed between the buckle and the stop to close the opening and confine the wire harnesses in the receiving space.

[0008] In this design, the buckle is placed inside the side panel and does not protrude from the side panel, thus achieving a side-hidden buckle effect. Users will only see the integrated side panel from the side, making the articulated arm more aesthetically pleasing and eye-catching. Moreover, there is no need to groove the side panel or its outer surface, and the side panel can maintain its integrity, thereby increasing the overall strength of the articulated arm and extending its service life.

[0009] Preferably, the main body is formed by bending a plate-shaped sheet, and the main body also includes a base plate located between the two side plates. The main body of the articulated arm is simple and convenient to form.

[0010] Preferably, the sheet metal has redundant portions at both ends in its width direction. After the sheet metal is bent into side plates and a bottom plate, the redundant portions are located at the upper end of the side plates. The redundant portions are configured to bend downwards and inwards at the upper end of the side plates to form the stop portions; the stop portions are the ends of the redundant portions. The stop portions can be directly bent into shape, which is convenient for production. Moreover, the stop portions are integrated with the side plates and the bottom plate, resulting in stronger integrity of the curved arm. The redundant portions, after being bent downwards, overlap with the side plates, which can further improve the overall strength of the curved arm.

[0011] Preferably, a U-shaped elastic element is provided inside the main body. The elastic element includes a connecting part that abuts against the bottom plate and two extension parts that abut against the two side plates respectively. The two ends of the connecting part are connected to the lower ends of the two extension parts respectively, and the buckle is provided at the upper end of the extension parts. The elastic element is U-shaped and easily deforms. The buckle is provided on the extension parts so that when the cover plate is installed, the buckle can move due to the deformation of the elastic element, allowing the cover plate to be inserted between the buckle and the stop part.

[0012] Preferably, the stop portion has a clearance groove for the clearance extension. The clearance groove not only allows the elastic element to be installed, but also limits the movement of the elastic element.

[0013] Preferably, the extension is provided with an abutment portion that protrudes inward from the extension. Simultaneously, both ends of the abutment portion protrude beyond the extension along its width. The abutment portion is configured such that after the extension enters the clearance groove, it abuts against the lower surface of the stop portion from bottom to top under the elastic deformation of the elastic member, filling the clearance groove. The abutment portion can abut against the lower surface of the stop portion due to the elastic force of the elastic member, thereby providing a limiting effect and preventing the elastic member from dislodging, ensuring the elastic member is stably installed within the main body and preventing the cover plate from malfunctioning.

[0014] Preferably, the thickness of the sheet material is 0.4mm-0.8mm. The thinness of the sheet material allows the side plates and bottom plate to have a certain degree of elastic deformation capability. Since the extension part abuts against the side plate, when the cover plate is installed, the outward expansion deformation of the extension plate will be restricted by the side plate and difficult to deform. However, due to the thinness of the sheet material, when the extension plate expands outward, the side plates and bottom plate will also be deformed under force. The side plates will expand outward, while the bottom plate will bend and arch. Although the deformation is not large, it is sufficient to allow the cover plate to be installed between the buckle and the stop part.

[0015] Preferably, both the extension and the connecting part are strip-shaped plates, with the thickness of the extension being less than that of the connecting part. The thicker connecting part prevents the elastic element from deforming and yielding in the connecting part after repeated installations of the cover plate over a long period, thus preventing deformation and failure of the elastic element. This is because during cover plate installation, the connecting part bends and arches as the extension expands outwards. If the yielding area is located in the connecting part, it will cause the connecting part to remain bent and arched, not only misaligning the clips on the extension plate but also preventing the abutting part from tightly contacting the stop part, thus making it easy for the elastic element to detach from the main body.

[0016] Preferably, the stop is arranged along the length of the side plate, and each side plate has two latches, which are spaced apart along the length of the side plate. Having more than one latch effectively improves the assembly stability of the cover plate.

[0017] As a preferred option, the buckle and side panel are integrally molded. Integrating the buckle and side panel is one possible solution, further simplifying the assembly process.

[0018] As a preferred option, the cover plate is made of felt. Felt combines elasticity and hardness, and also has a better texture and is more aesthetically pleasing.

[0019] Preferably, the cover plate has a notch at the corresponding buckle, and the width of the notch is less than the length of the buckle protruding from the side plate. The notch makes it easier for the cover plate to be inserted between the buckle and the stop, while the size configuration prevents the cover plate from detaching on its own.

[0020] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows: 1. In this solution, the buckle is set on the inside of the side panel and does not protrude from the side panel, thus achieving the side-hidden effect of the buckle. From the side, the user will only see the integrated side panel, making the articulated arm more beautiful and eye-catching. Moreover, there is no need to cut grooves on the side panel or the outer surface of the side panel, and the side panel can maintain its integrity, thereby increasing the overall strength of the articulated arm and extending its service life.

[0021] 2. The stop part can be directly bent and formed, which is convenient for production. The stop part, side plate and bottom plate are all integrated, which makes the articulated arm more integrated. The redundant part is bent down and overlaps with the side plate, which can further improve the overall strength of the articulated arm.

[0022] 3. The elastic element is U-shaped and easily deforms. The buckle is located on the extension, allowing the buckle to move due to the deformation of the elastic element during installation, so that the cover plate can be inserted between the buckle and the stop. The thinness of the sheet metal allows the side plate and bottom plate to have a certain elastic deformation capacity. Since the extension abuts against the side plate, when the cover plate is inserted, the outward expansion deformation of the extension plate will be restricted by the side plate and difficult to deform. However, due to the thinness of the sheet metal, when the extension plate expands outward, the side plate and bottom plate will also be deformed under force. The side plate will expand outward, and the bottom plate will bend and arch. Although the deformation is not large, it is enough to allow the cover plate to be inserted between the buckle and the stop. Attached Figure Description

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] The specific implementation of this utility model is as follows: like Figure 1 , 2As shown, this utility model provides a wire harness storage curved arm assembly 100, including a first moving arm 1, a linkage arm 2 rotatably connected to the first moving arm 1, and a second moving arm 3 rotatably connected to the linkage arm 2. The first moving arm 1 and the second moving arm 3 are respectively rotatably connected to different positions of the linkage arm 2. There is an angle between the first moving arm 1 and the second moving arm 3. When the first moving arm 1 and the second moving arm 3 move, the angle between them changes. A clamping area 4 is formed between the first moving arm 1, the linkage arm 2, and the second moving arm 3, and near the linkage arm 2. The linkage arm 2 is provided with a first limiting structure on the side facing the clamping area 4. The first limiting structure is configured such that when the first moving arm 1 and the second moving arm 3 rotate close to each other, the distance between the first moving arm 1 and the second moving arm 3 in the clamping area 4 is always greater than zero.

[0029] The cable harness storage arm assembly 100 can store the cable harness. When the tabletop 51 rises, the arm assembly restricts the lifting table and protects the cable harness from being pulled. When the tabletop 51 falls, the arm assembly restricts the cable harness and ensures that the cable harness does not droop or become tangled. Through the above scheme, the linkage arm 2 is set so that the rotation points of the first moving arm 1 and the second moving arm 3 are at different positions, and there is always a gap between the two rotation points. The double hinge point form replaces the single hinge point form. At the same time, the first limiting structure of the linkage arm 2 can limit the minimum included angle between the linkage arm 2 and the first and second moving arms, so that the linkage arm 2 and the two moving arms can be folded but cannot be folded to a state of mutual contact. Thus, the clamping area 4 can always have a space that cannot be closed by the moving arms and the linkage arm 2. The existence of this space can effectively prevent the hand from being pinched.

[0030] Specifically, such as Figure 3 , 4 As shown, the curved arm assembly is used in a height-adjustable desk, which is a double height-adjustable desk. It includes two tabletops 51, and two lifting columns 52 are connected to the bottom of each tabletop 51. Support beams 53 are installed between the lifting columns 52 on the same side under different tabletops 51. A base 54 is provided between the two support beams 53. A curved arm assembly 100 is provided between the base 54 and each of the two tabletops 51. The two moving arms of the curved arm assembly 100 are rotatably connected to the tabletop 51 and the base 54, respectively. When the tabletop 51 rises relative to the base 54, the two moving arms rotate away from each other. When the tabletop 51 falls relative to the base 54, the two moving arms rotate closer to each other. This allows the curved arm assembly 100 to open (unfold) or close (fold) with the rise and fall of the tabletop 51, adapting to the height-adjustable movement of the desk and protecting the wiring harness.

[0031] The first moving arm 1, the second moving arm 3, and the linkage arm 2 are all hollow. The first moving arm 1 forms a first receiving space 13, the second moving arm 3 forms a second receiving space 33, and the linkage arm 2 forms a third receiving space 24. The first moving arm 1 is located above the second moving arm 3, and the linkage arm 2 is located between them. The first receiving space 13 and the second receiving space 33 are connected through the third receiving space 24, allowing the wire harness to smoothly enter the curved arm assembly 100, pass through the curved arm assembly 100, and finally exit the curved arm assembly 100. The first moving arm 1 and the second moving arm 3 All are U-shaped long tubes with detachable covers. The linkage arm 2 is composed of two spaced splice pieces 21. The two ends of the splice piece 21 are rotatably connected to the sides of the two U-shaped long tubes. The length of the linkage arm 2 is much smaller than the length of the two moving arms. Specifically, the length of the linkage arm 2 is less than 32% of the length of the first moving arm 1 and less than 13% of the length of the second moving arm 3. In the curved arm assembly 100, the two moving arms mainly serve to accommodate the wire harness and move with the table 51, while the linkage arm 2 mainly serves to link and restrict the two moving arms.

[0032] Specifically, such as Figure 5-7 As shown, the first moving arm 1 includes a detachably connected first cover plate 11. When the first cover plate 11 is removed, a first opening 12 is formed on the first moving arm 1 along the length direction of the first moving arm 1. The first opening 12 is configured to allow the wire harness to enter the first receiving space 13 from the first opening 12. The first cover plate 11 is configured to close the first opening 12 to confine the wire harness in the first receiving space 13. Similarly, the second moving arm 3 includes a detachably connected second cover plate 31. When the second cover plate 31 is removed, a second opening 32 is formed on the second moving arm 3 along the length direction of the second moving arm 3. The second opening 32 is configured to allow the wire harness to enter the first receiving space 13 from the second opening 31. 2. Entering the second receiving space 33, the second cover plate 31 is configured to close the second opening 32 to confine the wire harness within the second receiving space 33; one end of the wire harness is connected to an electrical appliance, and the other end is a plug that needs to be plugged in to provide power. The size of the plug is much larger than the diameter of the wire harness. When installing the wire harness into the crank arm assembly 100, it is not reasonable to use the method of inserting the plug into the crank arm assembly 100, because this would result in an excessively large pipe diameter, leading to an increase in material costs. Therefore, it is more suitable to use the method of allowing the wire harness to enter directly. To allow the wire harness to enter directly, a sufficiently long opening needs to be provided, and the opening needs to be closed with the cover plate after the wire harness is installed to confine the wire harness inside the pipe.

[0033] The linkage arm 2 includes two spaced-apart splicing components 21. The two ends of each splicing component 21 are rotatably connected to the sides of the first moving arm 1 and the second moving arm 3, respectively. Each splicing component 21 includes a baffle 22 facing away from the clamping area 4. After the two splicing components 21 are installed on the moving arm, a gap exists between the two baffles 22, forming a third opening 23. The third opening 23 is configured to allow the wire harness to enter the third receiving space 24 from the third opening 23. The two baffles 22 are configured to confine the wire harness within the third receiving space 24. The linkage arm 2 consists of two identical splicing components 21, capable of... To reduce production costs and assembly difficulty, the length of the linkage arm 2 is much shorter than that of the two moving arms. Moreover, as the intermediate linkage component between the two moving arms, the linkage arm 2 needs to be hinged to both of them. Therefore, the opening of the linkage arm 2 is different from that of the moving arms to make it more reasonable. The third opening 23 is only the gap between the two baffles 22, but the size of the wire harness itself is small enough to allow the wire harness to enter the third receiving space 24 from the third opening 23. At the same time, the baffles 22 can prevent the wire harness from coming out of the third receiving space 24 again.

[0034] Furthermore, the first limiting structure is a plate-shaped first limiting plate 25. Each splicing component 21 is provided with a first limiting plate 25. The first limiting plate 25 is located on the other side of the baffle 22. The first limiting plate 25 is configured to prevent the first moving arm 1 or the second moving arm 3 from continuing to rotate when it moves to abut against the first limiting plate 25. The first limiting structure component has a simple structure and is also part of the linkage arm 2 itself, so no separate setting is required. The only thing to note is the size of the first limiting plate 25, which needs to be adapted to the lifting stroke of the lifting table. If it is too long, it will cause bending. If the folding degree of the arm assembly 100 is insufficient, the table 51 will be obstructed from descending or even damaged. If it is too short, it will not be able to play a good limiting role. We want the two moving arms to always open and close stably in the same direction. When the angle between the first moving arm 1 and the second moving arm 3 is controlled within 180°, the first moving arm 1 and the second moving arm 3 will not fold or unfold in the opposite direction. Folding or unfolding in the opposite direction is unpredictable and may cause injury to the user. Therefore, the first limiting plate 25 ensures that the angle between the first moving arm 1 and the second moving arm 3 is always less than 180°.

[0035] The linkage arm 2 is provided with a second limiting structure on the side facing away from the clamping area 4. The second limiting structure is configured to ensure that the first moving arm 1 and the second moving arm 3 are always located on one side of the linkage arm 2; that is, to ensure that the clamping area 4 is always located on one side of the linkage arm 2. Specifically, when the first moving arm 1 and the second moving arm 3 rotate away from each other, the angle between the first moving arm 1 and the second moving arm 3 is less than 180°.

[0036] Specifically, the second limiting structure is a plate-shaped second limiting plate 26. Both splicing parts 21 are provided with the second limiting plate 26. The second limiting plate 26 is located at the upper end of the baffle 22 and extends obliquely toward the clamping area 4. The second limiting plate 26 is configured to prevent the first moving arm 1 from continuing to rotate when it moves to abut against the second limiting plate 26. Similarly, the structure of the second limiting plate 26 is simple and is part of the linkage itself. The first limiting plate 25 limits the angle at which the two moving arms close, while the oblique second limiting plate 26 limits the angle at which the two moving arms open.

[0037] like Figure 2 , 3 As shown in Figure 7, an upper mounting base 14 is hinged to the upper end of the first moving arm 1, and the upper mounting base 14 is installed on the lower surface of the table 51. A lower mounting base 34 is hinged to the lower end of the second moving arm 3. The base 54 is hollow, and the lower mounting base 34 is installed in the base 54 and protrudes upward from the upper surface of the base 54 to be hinged with the second moving arm 3. The upper and lower ends of the first moving arm 1 and the second moving arm 3 are both open. Windows 55 are provided on the side of the base 54 and the side of the support beam 53 so that the plug on the wiring harness can finally leave the lifting table and connect to the power supply.

[0038] The first moving arm 1 and the second moving arm 3 have different included angles as the table 51 rises and falls. When the table 51 rises to its highest point, the included angle between the first moving arm 1 and the second moving arm 3 is the largest, which is the unfolded or open state. When the table 51 falls to its lowest point, the included angle between the first moving arm 1 and the second moving arm 3 is the smallest, which is the folded or closed state. During the change of included angle, the moving arms and the linkage arm 2 do not have a fixed movement sequence. That is, the first moving arm 1 and the linkage arm 2 can rotate, the second moving arm 3 and the linkage arm 2 can rotate, or both moving arms can rotate with the linkage arm 2 at the same time. However, due to the existence of the first and second limiting structures on the linkage arm 2, the curved arm assembly 100 has a maximum included angle and a minimum included angle to ensure the normal movement of the curved arm assembly 100 and the anti-pinch effect.

[0039] In addition, for the articulated arm assembly 100, the side profile integration and aesthetics are also points that consumers will pay attention to; such as Figure 9-11As shown, in this scheme, the first moving arm 1 and the second moving arm 3 also include a first main body 15 and a second main body 35, respectively. Taking the first moving arm 1 as an example, the first main body 15 includes two side plates 151 arranged at intervals. The first opening 12 and the first accommodating space 13 are formed between the two side plates 151. A buckle 16 and a stop 17 are provided on the inner side of each of the two side plates 151. Both the buckle 16 and the stop 17 protrude inward from the inner side of the side plate 151. The buckle 16 is located at the opening and the highest point of the buckle 16 is located below the highest point of the side plate 151. The stop 17 is located below the buckle 16. The detachable first cover plate 11 is disposed between the buckle 16 and the stop 17.

[0040] In this design, the buckle 16 is placed inside the side plate 151 and is not protruding from the side plate 151, thus achieving a side-hidden effect of the buckle 16. From the side, the user will only see the integrated side plate 151, making the first moving arm 1 more aesthetically pleasing and eye-catching. Moreover, there is no need to cut grooves on the side plate 151 or its outer surface, and the side plate 151 can maintain its integrity, thereby increasing the overall strength of the first moving arm 1 and extending its service life.

[0041] Both the buckle 16 and the stop 17 can be directly formed on the side plate 151 to simplify the assembly process and make production more convenient, but this will increase the production mold opening cost. Therefore, in this embodiment, the buckle 16 is installed by assembly, and the stop 17 is formed by bending. Specifically: like Figure 9-13 As shown, the stop portion 17 is arranged along the length direction of the side plate 151. Each side plate 151 is provided with two buckles 16, which are spaced apart along the length direction of the side plate 151. The number of buckles 16 is not one, which effectively improves the assembly stability of the cover plate. The first body 15 is formed by bending a plate-shaped sheet. The first body 15 also includes a bottom plate 152 located between the two side plates 151. The first body 15 is simple and convenient to form. At the same time, the sheet has redundant portions 153 at both ends in the width direction. The sheet is flat before bending. After the plate 151 and the base plate 152, the redundant part 153 is located at the upper end of the side plate 151. The redundant part 153 is first bent downwards so that it partially overlaps and abuts the side plate 151. Then, the end of the redundant part 153 is folded inwards to form the stop part 17. The stop part 17 is the end of the redundant part 153. The stop part 17 can be directly bent and formed, which is convenient for production. Moreover, the stop part 17, the side plate 151, and the base plate 152 are all integrated, which strengthens the integrity of the crank arm. After the redundant part 153 is bent downwards and overlaps with the side plate 151, the overall strength of the crank arm can be further improved.

[0042] Each side plate 151 has two clearance grooves 171 on its stop portion 17. The two clearance grooves 171 are spaced apart along the length of the side plate 151 and are close to the front and rear ends of the side plate 151. A U-shaped elastic member 18 is provided inside the first main body 15. The elastic member 18 includes a connecting portion 181 that abuts against the bottom plate 152 and two extension portions 182 that abut against the two side plates 151 respectively. The two extension portions 182 are respectively located in the clearance portions 17 of the two side plates 151. In the groove 171, the two ends of the connecting part 181 are respectively connected to the lower ends of the two extension parts 182, and the buckle 16 is disposed at the upper end of the extension part 182; the elastic element 18 is U-shaped and easily deforms, and the buckle 16 is disposed on the extension part 182 so that when the cover plate is installed, the buckle 16 can move due to the deformation of the elastic element 18, so that the cover plate can be inserted between the buckle 16 and the stop part 17; the clearance groove 171 not only allows the elastic element 18 to be installed, but also limits the elastic element 18.

[0043] The extension 182 is also provided with an abutment portion 183, which protrudes inward from the extension 182. Simultaneously, along the width direction of the extension 182, both ends of the abutment portion 183 protrude from the extension 182. The abutment portion 183 is configured such that after the extension 182 enters the clearance groove 171, under the elastic deformation of the elastic member 18, the abutment portion 183 abuts against the lower surface of the stop portion 17 from bottom to top and fills the clearance groove 171. The abutment portion 183 can abut against the lower surface of the stop portion 17 due to the elastic force of the elastic member 18, thereby providing a limiting effect and preventing the elastic member 18 from dislodging, ensuring that the elastic member 18 is stably disposed within the first main body 15, and preventing the function of the mounting cover from failing.

[0044] Furthermore, the thickness of the plate is 0.4mm-0.8mm. The thinness of the plate allows the side plate 151 and the bottom plate 152 to have a certain elastic deformation capacity. Since the extension 182 abuts against the side plate 151, when the cover plate is installed, the outward expansion deformation of the extension plate will be restricted by the side plate 151 and difficult to deform. However, due to the thinness of the plate, when the extension plate expands outward, the side plate 151 and the bottom plate 152 will also be deformed by force. The side plate 151 will expand outward, while the bottom plate 152 will bend and arch. Although the deformation is not large, it is enough to allow the cover plate to be installed between the buckle 16 and the stop 17.

[0045] Both the extension 182 and the connecting part 181 are strip-shaped plates. The thickness of the extension 182 is less than that of the connecting part 181. The connecting part 181 is thicker to prevent the deformation yielding area of ​​the elastic element 18 from being located in the connecting part 181 after repeated installation of the cover plate over a long period of time, which would cause the elastic element 18 to deform and fail. When the cover plate is installed, the connecting part 181 will bend and arch as the extension 182 expands outward. If the yielding area is located in the connecting part 181, the connecting part 181 will always bend and arch, which will not only cause the buckle 16 on the extension plate to be misaligned, but also prevent the abutting part 183 from being tightly abutting with the stop part 17, thus making it easy for the elastic element 18 to detach from the first body 15.

[0046] The first cover plate 11 is made of felt. The first cover plate 11 has a notch 111 at the corresponding buckle 16, and the width of the notch 111 is less than the length of the buckle 16 protruding from the side plate 151. In this solution, the felt has both elasticity and hardness, and has a better texture and is more beautiful. The presence of the notch 111 makes it easier for the cover plate to be inserted between the buckle 16 and the stop part 17. At the same time, the size configuration can prevent the cover plate from falling off by itself.
