[0064] Example 1

[0065] This embodiment provides a bed, which includes a mattress and a bed frame. The bed frame is used to support the mattress and provide good support for the mattress.

[0066] If the bed frame is a fixed structure, since the bed frame is generally large in size, the user will have problems such as large space occupation and difficulty in carrying during subsequent use. Figure 1-Figure 2 As shown, the bed frame includes a first connecting member 200 , a second connecting member 300 and a bed frame connecting structure 100 . One end of the bed frame connecting structure 100 is rotatably connected to the first connecting member 200 , and the other end is rotatably connected to the second connecting member 300 .

[0067] The first connecting member 200 and the second connecting member 300 of the bed frame are connected by the bed frame connecting structure 100, which ensures the stability of the connection between the first connecting member 200 and the second connecting member 300. At the same time, both ends of the bed frame connecting structure 100 are rotatably connected to the first connecting member 200 and the second connecting member 300, so the connection between the first connecting member 200 and the second connecting member 300 is not a rigid connection, but a relatively movable arrangement. Figure 1 As shown, if the first connecting member 200 and the second connecting member 300 rotate toward each other through the bed frame connecting structure 100, the first connecting member 200 and the second connecting member 300 approach each other, realizing the folding state of the bed frame; Figure 2 As shown, if the first connecting member 200 and the second connecting member 300 rotate away from each other through the bed frame connecting structure 100, the first connecting member 200 and the second connecting member 300 are separated from each other, and the bed frame is in an unfolded state.

[0068] In one embodiment, the first connecting member 200 is a frame, and the second connecting member 300 is a supporting leg, and the supporting leg is disposed on the frame.

[0069] Specifically, the supporting legs can be arranged at the bottom of the frame, and the supporting legs provide supporting force for the frame. The bed frame connecting structure 100 is arranged between the frame and the supporting legs. The bed frame connecting structure 100 is inclined relative to the bed frame and the supporting legs. When the bed frame is in the unfolded state, a triangular structure is formed between the bed frame, the supporting legs and the bed frame connecting structure 100. Taking advantage of the good stability of the triangular structure, the stability between the bed frame and the supporting legs is good; when the bed frame is in the folded state, the supporting legs and the bed frame connecting structure 100 are respectively fitted with the bed frame, taking up little space and being convenient for storage and transportation.

[0070] It can be understood that the first connecting member 200 includes but is not limited to a frame, and the second connecting member 300 includes but is not limited to a supporting leg. The first connecting member 200 and the second connecting member 300 can also be other structures. For example, the first connecting member 200 is the frame border, and the second connecting member 300 is the connecting rod of the frame. The bed frame connecting structure 100 is used to adjust the distance between the connecting rod and the frame; or the first connecting member 200 and the second connecting member 300 are oppositely arranged horizontal bars or vertical bars, and two adjacent horizontal bars can be connected by the bed frame connecting structure 100. The bed frame connecting structure 100 can be used to adjust the width and length of the bed frame, which is convenient and flexible.

[0071] This embodiment also provides a bed frame connection structure 100, such as Figure 3-Figure 4 As shown, the bed frame connection structure 100 includes a first support member 1, a second support member 2 and a locking assembly 3. The first support member 1 is rotatably connected to the first connection member 200 of the bed frame, and the second support member 2 is rotatably connected to the second connection member 300 of the bed frame. Figure 5-Figure 6 As shown, one of the first support member 1 and the second support member 2 is provided with a slideway 21 , and the other is provided with a fixing hole 11 , and the locking assembly 3 is penetrated through the slideway 21 and the fixing hole 11 along the axial direction of the locking assembly 3 .

[0072] The axial direction of the locking assembly 3 is the first direction, which can be identified by D1; the extension direction of the slide 21 is the second direction, which can be identified by D2; and the width direction of the slide 21 is the third direction, which can be identified by D3. The axial direction of the locking assembly 3, the extension direction of the slide 21, and the width direction of the slide 21 are mutually perpendicular. These three directions merely represent spatial directions and have no substantive meaning. It is understandable that as the first support member 1 and the second support member 2 rotate, the positions of the slide 21 and the locking assembly 3 provided on the support members will also change in three-dimensional space. Although these three directions will also change accordingly, the perpendicular relationship between these three directions will not change.

[0073] The locking assembly 3 is configured to be pressed along the axial direction of the locking assembly 3 so that the locking assembly 3 slides along the slide 21, and the second support member 2 and the first support member 1 can slide relative to each other, and is used to switch between the first connecting member 200 and the second connecting member 300 between the folded state and the unfolded state.

[0074] Since one of the first support member 1 and the second support member 2 is provided with a slide 21 and the other is provided with a fixing hole 11, the locking component 3 is passed through the slide 21 and the fixing hole 11, and the locking component 3 realizes the connection between the first support member 1 and the second support member 2. The locking component 3 is fixed relative to the fixing hole 11. When the locking component 3 is in a locked state, the first support member 1 and the second support member 2 cannot move relative to each other. The first support member 1 and the second support member 2 can be in an expanded state (such as Figure 2As shown), at this time, the first connecting member 200 and the second connecting member 300 are also in the unfolded state. After pressing the locking assembly 3 along the axial direction of the locking assembly 3, the locking assembly 3 can slide along the slide 21. The slide 21 plays a role in guiding and path planning for the locking assembly 3. The locking assembly 3 is in the unlocked state, and the first support member 1 and the second support member 2 can slide relative to each other. As the first support member 1 and the second support member 2 extend or shorten, the relative positions of the first connecting member 200 and the second connecting member 300 will also change. At this time, the first support member 1 and the second support member 2 are in the folded state (as shown). Figure 1 As shown), at this time, the first connecting member 200 and the second connecting member 300 are also in a folded state.

[0075] The locking assembly 3 can be unlocked and locked by simply pressing it, which is simple to operate, simplifies the user's use process, saves time and effort, and improves user satisfaction. The pressing direction of the locking assembly 3 is the same as the insertion direction of the locking assembly 3, which is more in line with the user's operating habits and further improves the convenience of use. The pressing force on the locking assembly 3 can be directly converted into the unlocking driving force of the locking assembly 3. There are no intermediate force transmission components and changes in the force transmission direction. The unlocking process responds quickly and is highly reliable.

[0076] Among them, the distance between the bed frame connecting structure 100 and the second connecting member 300 along the first direction is approximately 5cm to 10cm, preferably 8cm, so that it just fits the width of the palm of a human hand when unfolded or folded. Both hands can press the locking component 3 and lift or press the second connecting member 300 at the same time, which is convenient and ergonomic to operate.

[0077] It can be understood that as the first support member 1 extends or contracts relative to the second support member 2, the relative positions of the first connecting member 200 and the second connecting member 300 connected to the two support members will change. The first support member 1 is rotated to be connected to the first connecting member 200, and the second support member 2 is rotated to be connected to the second connecting member 300 to compensate for the position change.

[0078] In one embodiment, Figure 3-Figure 6 As shown, the first support member 1 and the second support member 2 extend along the second direction, and are specifically long rod-shaped structures. The lengths of the first support member 1 and the second support member 2 along the second direction can be approximately the same, and the widths of the first support member 1 and the second support member 2 along the third direction can be approximately the same, so that in the folded state, the first support member 1 and the second support member 2 overlap with each other after being shortened, saving space.

[0079] In one embodiment, at least one end of the first support member 1 and the second support member 2 along the second direction may be an arc structure to prevent the user from being scratched by sharp corners during operation.

[0080] In one embodiment, a first angle bracket is provided between the first support member 1 and the first connecting member 200. The first angle bracket has an L-shaped structure, one side arm of which is bolted to the first connecting member 200, and the other side arm of which is connected to the first support member 1 via a first rotating shaft. A second angle bracket is provided between the second support member 2 and the second connecting member 300. The first angle bracket has an L-shaped structure, one side arm of which is bolted to the second connecting member 300, and the other side arm of which is connected to the second support member 2 via a second rotating shaft.

[0081] Among them, the first support member 1 is provided with a fixing hole 11, and the second support member 2 is provided with a slide 21. Of course, the positions of the fixing hole 11 and the slide 21 can also be interchanged. For example, the slide 21 is provided on the first support member 1, and the fixing hole 11 is provided on the second support member 2. The specific structure and principle are similar, so they will not be traced in detail.

[0082] In one embodiment, Figure 5 As shown, the slideway 21 includes a connecting slide groove 211 and a locking hole 212. The locking assembly 3 is inserted through the locking hole 212 and the fixing hole 11, and is in the locked state. The locking assembly 3 is inserted through the fixing hole 11 and the slide groove 211 and can slide with the slide groove 211, and is in the unlocked state. Because the locking hole 212 and the slideway 21 are interconnected, the locking assembly 3 can slide directly from the locking hole 212 into the slide groove 211, making the transition between the folded state and the unfolded state seamless and smooth.

[0083] In one embodiment, the locking hole 212 is disposed on at least one side of the sliding groove 211 along the extending direction of the slideway 21 .

[0084] For example, the locking hole 212 is provided on a side of the chute 211 close to the second connector 300, that is, the locking hole 212 is located below the chute 211. When the first support member 1 and the second support member 2 move toward each other, the first support member 1 and the second support member 2 shorten, and the locking assembly 3 is provided through the locking hole 212. At this time, the first support member 1 and the second support member 2 shorten, and the locking assembly 3 is provided through the locking hole 212. At this time, the first support member 1 and the second support member 2 shorten, and the locking assembly 3 is provided through the locking hole 212. At this time, the first support member 200 and the second connector 300 are locked in the unfolded state, thereby ensuring the positional stability of the first connector 200 and the second connector 300 in the unfolded state. Of course, the locking hole 212 can also be provided on a side of the chute 211 close to the first connector 200, that is, the locking hole 212 is located above the chute 211. When the first support member 1 and the second support member 2 move away from each other, the first support member 1 and the second support member 2 shorten, and the locking assembly 3 is provided through the locking hole 212. At this time, the first support member 200 and the second connector 300 are locked in the folded state, thereby ensuring the positional stability of the first connector 200 and the second connector 300 in the folded state.

[0085] It can be understood that the number of locking holes 212 can be one, and the locking hole 212 is arranged at the end of the slide groove 211; the number of locking holes 212 can also be two, and the two locking holes 212 are respectively arranged at the two ends of the slide groove 211, so that the first support member 1 and the second support member 2 can ensure good position stability in the unfolded state and the folded state.

[0086] In one embodiment, Figure 5 As shown, the locking holes 212 are symmetrically arranged relative to the axial direction of the sliding groove 211.

[0087] That is, the locking hole 212 is not eccentrically arranged relative to the slide groove 211, but the axis of the slide groove 211 passes through the center of the locking hole 212. The transition between the slide groove 211 and the locking hole 212 is smooth and without corners. During use, the user does not need to lift or press down the locking component 3 in the third direction. The locking component 3 can slide smoothly and smoothly between the locking hole 212 and the slide groove 211. It is easy to operate and use, and the risk of jamming during state switching is reduced.

[0088] In one embodiment, Figure 7 As shown, the locking assembly 3 includes a locking member 31, and the locking member 31 includes a guide portion 311 and a locking portion 312. The guide portion 311 and the locking portion 312 are interconnected and coaxially arranged. The guide portion 311 can be inserted into the slide groove 211 and slidably cooperate with the slide groove 211. The locking portion 312 can be inserted into the locking hole 212 and the fixing hole 11.

[0089] Since the slide 21 includes two parts, the slide groove 211 and the locking hole 212, the guide part 311 and the locking part 312 of the locking member 31 correspond to these two parts respectively. When the bed frame is unfolded or folded, the guide part 311 of the locking member 31 can slide in the slide groove 211 until it reaches the locking hole 212. The guide part 311 and the locking part 312 are coaxially arranged. When the locking member 31 is pressed along the first direction, the locking part 312 will fall into the locking hole 212, completing the locking action. At this time, a stable support effect is formed between the first connecting member 200 and the second connecting member 300.

[0090] It is understood that the outer contours of the locking portion 312 and the locking hole 212 are compatible. For example, the locking portion 312 may be cylindrical and the locking hole 212 may be circular. Alternatively, the locking portion 312 may be rectangular and the locking hole 212 may be square. Of course, the locking portion 312 and the locking hole 212 may also have other structures and shapes. The outer contours of the chute 211 and the guide portion 311 are compatible. The guide portion 311 may be cylindrical and the chute 211 may be elongated. The ends of the chute 211 along the second direction are arc-shaped structures to match the guide portion 311.

[0091] In one embodiment, along the width direction of the slideway 21 , the width dimension of the locking hole 212 is greater than the width dimension of the slide groove 211 .

[0092] When the locking hole 212 is a circular hole, the slide 21 is composed of a strip-shaped slide groove 211 and a locking hole 212 whose diameter is greater than the width of the slide groove 211. The sizes of the guide portion 311 and the locking portion 312 of the locking member 31 are correspondingly distinguished. When the guide portion 311 and the locking portion 312 are both cylindrical structures, the diameter of the guide portion 311 is smaller than the diameter of the locking portion 312. The guide portion 311 can be called a small neck and the locking portion 312 can be called a large neck. The diameter of the guide portion 311 is slightly smaller than the width of the slide groove 211, so that the guide portion 311 can slide freely along the slide groove 211. The diameter of the locking portion 312 is slightly smaller than the diameter of the locking hole 212, and the locking portion 312 can be accommodated in the diameter of the locking hole 212.

[0093] In one embodiment, along the width direction of the slideway 21 , the width dimension of the locking portion 312 is greater than the width dimension of the guiding portion 311 .

[0094] In this manner, if the locking member 31 is not pressed in the first direction, the locking portion 312 can only be located in the locking hole 212, rather than moving into the slide groove 211. At this time, the locking member 31 is temporarily fixed relative to the locking hole 212, and the first support member 1 and the second support member 2 are also relatively fixed, ensuring a stable support between the first connecting member 200 and the second connecting member 300. When the locking member 31 is pressed in the first direction, the locking portion 312 is released from the locking hole 212, and the guide portion 311 can slide from the locking hole 212 into the slide groove 211, completing the unlocking process.

[0095] In one embodiment, the locking member 31 further includes a stopping portion 313 , and the stopping portion 313 is disposed on at least one of the sides of the guide portion 311 and the locking portion 312 that are away from each other.

[0096] That is, the stop portion 313 is set on the outside of the guide portion 311 or the locking portion 312. Since the locking member 31 needs to be pressed along the first direction, the stop portion 313 can be used to prevent the locking member 31 from falling out of the slide 21, thereby achieving the limitation of the guide portion 311 and / or the locking portion 312.

[0097] In one embodiment, along the width direction of the slideway 21 , the width dimension of the stop portion 313 is greater than the width dimension of the locking hole 212 .

[0098] In this manner, the stopper 313 is relatively wide and located outside the guide portion 311 or the locking portion 312. This provides the user with a larger pressing area, making it easier for the user to press and unlock the lock. Furthermore, the larger stopper 313 will not enter the locking hole 212, making it easier for the user to press the stopper 313 again later.

[0099] It should be noted that if Figure 7 As shown, the locking member 31 can be composed of a screw and a T-nut. The T-nut has a large end and a small end. The threaded portion of the screw is threadedly connected to the small end of the T-nut. In this case, the threaded portion of the screw is the guide portion 311, and the small end of the T-nut is the locking portion 312. The large end of the T-nut and the nut of the screw serve as the stopper 313. Assembling the locking portion 312 in this manner has a simple structure and low production cost. During installation, the threaded portion of the screw can first be inserted into the locking hole 212 and the fixing hole 11, and then the threaded portion of the screw can be threadedly connected to the small end of the T-nut, which has the advantage of easy installation.

[0100] It should be noted that if Figure 8-Figure 9 As shown, the locking member 31 can be composed of a sleeve and a rivet. One end of the rivet is a stepped shaft with a large shaft and a small shaft. The large shaft is connected to the shank of the rivet through the small shaft. The other end of the rivet is riveted to the sleeve. In this case, the shank of the rivet serves as a guide portion 311, the small shaft of the stepped shaft serves as a locking portion 312, and the large shaft and sleeve of the stepped shaft serve as stop portions 313. During installation, the shank of the rivet can be first inserted into the locking hole 212 and the fixing hole 11, and then the rivet can be riveted to the sleeve. This simple structure is easy to install.

[0101] In one embodiment, Figure 6-Figure 8 As shown, the locking assembly 3 further includes a reset member 32 , which is sleeved on the outside of the locking member 31 and disposed between the first support member 1 and the stop portion 313 of the locking member 31 , and is elastic and used for resetting the locking member 31 .

[0102] When the bed frame needs to be folded, the stopper 313 of the locking portion 312 is pressed by external force. The reset member 32 may optionally be a spring. The spring compresses and pushes the locking portion 312 away from the locking hole 212, allowing the first support member 1 and the second support member 2 to slide relative to each other and extend, and the first connecting member 200 and the second connecting member 300 to fold toward each other. When the bed frame needs to be unfolded, the second connecting member 300 is lifted, and the first support member 1 and the second support member 2 can slide relative to each other and shorten. Because the compressed reset member 32 has an elastic force, under this elastic force, the locking portion 312 can enter the locking hole 212, completing the self-locking process. At this time, the second connecting member 300 is also lifted into place. Using this method, the bed frame is very simple to operate when folding and unfolding, and the pressing direction of the reset member 32 also makes the user's operation more convenient, which is convenient for the user to operate.

[0103] In one embodiment, Figure 10 As shown, at least one of the first support member 1 and the second support member 2 is provided with a limiting portion 4 , and the limiting portion 4 is used for limiting the position between the first support member 1 and the second support member 2 .

[0104] For example, the limiting portion 4 is provided on the first support member 1, and the limiting portion 4 limits the relative positions of the two support members. When the first support member 1 and the second support member 2 slide relative to each other, the limiting portion 4 can prevent the first support member 1 and the second support member 2 from being offset in position due to rotation, so that the two can be kept in the same straight line as much as possible during the extension or contraction process along the second direction.

[0105] The edge of the limiting portion 4 is rounded, and the connection position between the limiting portion 4 and the first support member 1 is transitioned through an arc to reduce the risk of scratches to the user during use.

[0106] In one embodiment, the stopper 4 corresponding to the first support member 1 is integrally formed with the first support member 1, thereby reducing the number of assembly steps required for the first support member 1 and the stopper 4 and saving production costs. Specifically, during actual production, the first support member 1 can be bent upward along its edge, which simplifies the process and reduces production costs.

[0107] Among them, the first support member 1 and the limiting portion 4 are set at an angle. For example, the first support member 1 and the limiting portion 4 are perpendicular to each other, and the angle between them is 90°. Of course, the angle between the first support member 1 and the limiting portion 4 can also be an acute angle or an obtuse angle.

[0108] In one embodiment, the limiting portion 4 extends along the extending direction of the slideway 21 .

[0109] That is, the limiting portion 4 extends along the second direction, the extending direction of the limiting portion 4 is the same as the sliding direction of the locking assembly 3, and the relative sliding direction of the first support member 1 and the second support member 2 is the same as the extending direction of the limiting portion 4. In this way, during the extension and contraction of the first support member 1 and the second support member 2, the locking member 31 can limit the first support member 1 and the second support member 2, thereby improving the limiting effect.

[0110] It is understandable that the present embodiment does not limit the length of the limiting portion 4 along the second direction. The length of the limiting portion 4 can be relatively small, so that the limiting portion 4 is similar to a block-shaped structure (such as Figure 10 As shown), the length of the limit portion 4 can also be relatively large (as shown Figure 11 As shown), for example, the length of the limit portion 4 is greater than or equal to the length of the slide 21, that is, the limit range of the limit portion 4 for the first support member 1 and the second support member 2 completely covers the telescopic range, further preventing the two support members from positionally offsetting during the mutual sliding process.

[0111] In one embodiment, the limiting portion 4 is provided on at least one side of the first support member 1 along the width direction of the slideway 21 .

[0112] For example, there is one limiting portion 4, one limiting portion 4 being provided on either side of the first support member 1 along the third direction. The first support member 1 and the limiting portion 4 form an L-shaped structure, which can achieve single-sided positioning of the two support members along the third direction. Alternatively, there are two limiting portions 4, two limiting portions 4 being provided on either side of the first support member 1 along the third direction. The two limiting portions 4 are arranged parallel and facing each other. In this case, the first support member 1 and the two limiting portions 4 form a U-shaped structure, which can achieve bilateral positioning of the two support members along the third direction. With this structure, during assembly, the second support member 2 is passed through the U-shaped structure from one end of the first support member 1 along the second direction. The two limiting portions 4 also serve to a certain extent as a guide during the installation or disassembly process.

[0113] It can be understood that the limiting portion 4 can be set not only on the first support member 1, but also on the second support member 2. The limiting portion 4 is set on at least one side of the second support member 2 along the width direction of the slide 21 to achieve unilateral or bilateral limitation of the first support member 1 and the second support member 2 in the third direction.

[0114] In one embodiment, Figure 11 As shown, along the width direction of the slideway 21 , an extension portion 5 is provided on a side of the limiting portion 4 away from the first support member 1 and toward the slideway 21 .

[0115] That is, the free end of the limiting portion 4 is bent inward to form an extension portion 5, and the limiting portion 4 and the extension portion 5 form an L-shaped structure. At this time, the limiting portion 4 is used to limit the first support member 1 and the second support member 2 along the third direction, and the extension portion 5 is used to limit the first support member 1 and the second support member 2 along the first direction, further improving the limiting effect between the two support members and preventing the two support members from being offset in position.

[0116] Example 2

[0117] This embodiment is similar to the first embodiment, and the only difference is the connection structure between the first support member 1 , the second support member 2 and the limiting portion 4 .

[0118] like Figure 12-13 As shown, the first support member 1 and the second support member 2 provided in this embodiment both have a limiting portion 4, and the limiting portion 4 corresponding to the first support member 1 and the limiting portion 4 corresponding to the second support member 2 are in contact with each other and guided to fit on one side close to each other.

[0119] In this way, during the relative sliding of the first support member 1 and the second support member 2, the limiting parts 4 corresponding to the two support members contact each other, increasing the contact area of ​​the two support members during the sliding process, improving the guiding matching effect, and further improving the limiting effect, preventing the two support members from positional displacement.

[0120] The limiting portion 4 corresponding to the first support member 1 and the limiting portion 4 corresponding to the second support member 2 can be located on the same side of the first support member 1, so that the first support member 1 and the second support member 2 can contact each other. The distance between the inner walls of the two limiting portions 4 corresponding to the first support member 1 is slightly greater than the distance between the outer walls of the two limiting portions corresponding to the second support member 2, so that the second support member 2 and the first support member 1 can be nested with each other.

[0121] In some other embodiments, the limiting portion 4 of the first support member 1 and the limiting portion 4 of the second support member 2 can also be located on the same side of the first support member 1 and arranged opposite each other along the first direction. Then, there is no contact between the first support member 1 and the second support member 2, but there is a certain gap between them. However, the limiting portions 4 of the two support members can be used for guidance.

[0122] Example 3

[0123] This embodiment is similar to the first embodiment, and the only difference is the connection structure between the first support member 1 , the second support member 2 and the limiting portion 4 .

[0124] like Figure 14-17As shown, the two limiting parts 4 corresponding to the first support member 1 provided in this embodiment are arranged in parallel and opposite each other, and the two limiting parts 4 corresponding to the first support member 1 are connected by a first connecting part 6, so that a first tubular structure is formed between the first support member 1, the two limiting parts 4 and the first connecting part 6, and the second support member 2 is passed through the first tubular structure and slidably cooperates with it.

[0125] In this manner, the two limiting portions 4 are arranged in parallel and facing each other, and the first support member 1 and the first connecting portion 6 are arranged in parallel and facing each other. Then, the first support member 1, one of the limiting portions 4, the first connecting portion 6, and the other limiting portion 4 are connected end to end to form a first tubular structure. The cavity of the first tubular structure is used to accommodate the second support member 2. Because the first tubular structure is relatively closed, the first support member 1 and the second support member 2 can simultaneously achieve positional limitation along the first direction and the third direction.

[0126] In one embodiment, the two limiting portions 4 corresponding to the second support member 2 are arranged in parallel and opposite to each other, and the two limiting portions 4 corresponding to the second support member 2 are connected by a second connecting portion (not shown in the figure), so that a second tubular structure (not shown in the figure) is formed between the second support member 2, the two limiting portions 4 and the second connecting portion, and the first support member 1 is passed through the second tubular structure and slidably cooperates with it.

[0127] In this manner, the two limiting portions 4 are arranged in parallel and facing each other, and the second support member 2 and the second connecting portion are arranged in parallel and facing each other. Then, the first support member 1, one of the limiting portions 4, the second connecting portion, and the other limiting portion 4 are connected end to end to form a second tubular structure. The cavity of the second tubular structure is used to accommodate the first support member 1. Because the second tubular structure is relatively closed, it can simultaneously achieve positional limitation between the first support member 1 and the second support member 2 along the first direction and the third direction.

[0128] Of course, in some other embodiments, the first tubular structure and the second tubular structure may be provided at the same time, and the two tubular structures are nested with each other to further increase the guiding contact area and the limiting effect.
