Description

Technical Field

[0001] This application relates to the field of functional furniture technology, and in particular to a control rotation and telescopic mechanism. Background Technology

[0002] Multifunctional furniture is a type of product that, while retaining the basic functions of traditional furniture, adds new features. It represents a reinvention of furniture. One of the most significant characteristics distinguishing multifunctional furniture from traditional furniture is its ingenious adjustable structure. For small and medium-sized apartments with limited space, wall beds, storage tables, and similar items can be moved, transformed, or folded to allow their supporting surfaces to be stored on the wall. However, the support legs used to support the supporting surfaces must maintain a fixed angle with the surface during use to ensure stable support.

[0003] Existing technologies typically employ an integrated electromechanical structure. This involves folding down the main body of the furniture and then synchronously controlling the rotation of the supporting legs to allow them to be folded into place on the wall, or controlling the rotation of the supporting legs to support the main body while it is in use. However, the electromechanical control connection and installation process is relatively complicated, and maintenance can easily lead to high costs.

[0004] Therefore, based on the above problems, the existing technology needs to be improved. Summary of the Invention

[0005] The purpose of this application is to enable the support legs to be stored or used in sync with the main body of the furniture through a precise and stable mechanical adjustment structure.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a control rotation and telescopic mechanism, including a box body, a cavity for holding objects inside the box body, an opening on the box body, the opening and the cavity being connected, a fixing member on the cavity wall of the cavity, a sliding member on the fixing member, one end of the sliding member being able to slide or rotate on the fixing member, the other end passing through the opening for connecting a support foot, a guide component on the sliding member, a guide rail being hollowed out on the sliding member, the guide component passing through the guide rail, a drive component on the guide component, the drive component driving the guide component to slide on the fixing member, causing the guide rail on the sliding member to abut or avoid the guide component, thereby driving the sliding member to slide or rotate on the fixing member.

[0007] By adopting the above technical solution, the entire mechanism and the frame of the main body of the furniture, such as the bed or desktop, are fixedly set in the box, so that the support legs connected to the mechanism are installed and connected to the main body of the furniture. The functional furniture flip-adjustment mechanism provides power to the drive component, which drives the guide component to slide relative to the fixed part. When the guide rail wall on the guide component and the sliding part is limited, the guide component drives the sliding part to slide synchronously on the fixed part, so that the support leg connected to the sliding part can extend and retract relative to the main body of the furniture, so that the support leg is closer to or further away from the main body of the furniture, avoiding the support leg being easily blocked by the frame of the main body of the furniture during subsequent rotation or storage, thus preventing it from becoming unusable. When the sliding direction of the guide rail and the sliding part is not in a straight line, the sliding part is squeezed by the guide component and rotates. The sliding part avoids the guide component through the guide rail, so that the support leg connected to the sliding part can rotate relative to the main body of the furniture. When the support leg rotates to be parallel to the plane of the main body of the furniture, it is stored together, reducing the storage space of the furniture. Alternatively, the support leg can be rotated to form a certain angle with the plane of the main body of the furniture, so that the support leg can stably support the main body of the furniture. By using two types of guide rails on the slider, the slider and guide assembly can make contact or avoid each other. Through a precise and stable mechanical adjustment structure, the support legs can be stored or used in sync with the main body of the furniture.

[0008] Optionally, the fixing member is hollow in the axial direction to form a sliding channel. The sliding member and the guide assembly are fitted inside the fixing member. The fixing member is hollow in the axial direction to form a relief groove. The relief groove and the sliding channel are connected. The guide assembly can pass through the relief groove and be installed and connected to the drive assembly.

[0009] By adopting the above technical solution, the sliding channel assembly guides and sliders enable the sliders to rotate precisely and stably within the sliding channel and slide relative to the fixed parts, thereby controlling the support legs connected to the sliders to rotate stably and slide closer to or away from the main frame of the furniture.

[0010] Optionally, the sliding member is hollow in the axial direction to form an installation channel. The guide rail includes a transverse opening that is connected to the installation channel. The guide assembly includes a first shaft that is fitted into the installation channel. A first guide is provided on the first shaft. One end of the first guide is connected to the first shaft, and the other end is provided with a transverse opening and a clearance groove.

[0011] By adopting the above technical solution, driven by the drive component, the sliding direction of the first guide member is inconsistent with the direction of the transverse opening, causing the first guide member and the transverse opening groove wall to be limited. The first guide member drives the slider to slide along the avoidance groove on the fixed member, allowing the support foot connected to the slider to slide closer to or further away from the furniture body relative to the fixed member, preventing the support foot from being stuck and unable to provide support. When the slider rotates relative to the fixed member, it avoids the first guide member through the transverse opening, preventing the slider from getting stuck on the first guide member and thus preventing the rotation function from being achieved.

[0012] Optionally, the guide rail also includes multiple guide grooves, and the guide assembly also includes a second shaft. The second shaft is provided with a second guide component. The second shaft is fitted into the installation channel. The second shaft is provided with a second guide component. One end of the second guide component is connected to the second shaft, and the other end is provided with multiple guide grooves and clearance grooves.

[0013] By adopting the above technical solution, driven by the drive component, when the first guide member drives the slider to slide on the fixed member, the second guide member slides relative to the slider. The second guide member limits and abuts against the multi-segment guide groove, causing the second guide member to drive the slider to rotate. The multi-segment guide groove on the slider avoids the sliding of the second guide member, so that the slider can rotate in the direction perpendicular to the sliding of the second guide member, thereby causing the support foot connected to the slider to rotate for storage or support.

[0014] Optionally, the multi-segment guide groove includes a first guide groove, which is arranged along the axial direction of the slider. A second guide groove is connected to one end of the first guide groove near the opening. The second guide groove is a straight or curved groove that is not parallel to the sliding direction of the slider. A third guide groove is connected to one end of the second guide groove away from the first guide groove. The third guide groove is parallel to the first guide groove.

[0015] By adopting the above technical solution, when the drive component drives the first guide and the second guide to move the slider along the axis on the fixed part, the first guide groove avoids the second guide, so that the second guide and the first guide synchronously generate relative displacement on the fixed part and then abut against the wall of the second guide groove. As the second guide continues to slide relative to the fixed part along the avoidance groove, the second guide abuts against the wall of the second guide groove to create a limit. Since the setting direction of the second guide groove is a straight or curved groove that is not parallel to the sliding direction of the slider, the second guide squeezes the second guide groove, causing the slider as a whole to rotate towards the side of the slider being subjected to force. The slider avoids the second guide through the second guide groove. When the support foot connected to the slider rotates to a suitable angle with the support body, it slides relative to the third guide groove through the second guide, so that the slider continues to extend and retract after rotation, making the support foot stable in the state after rotation, avoiding the inability to stably support the support body after the support foot completes rotation.

[0016] Optionally, the curved surface of the second guide groove wall is configured to form a guide surface.

[0017] By adopting the above technical solution, the guide surface is set so that the groove walls on both sides of the second guide groove can stably clamp the second guide member when the slider rotates, so that the second guide member can slide stably in the second guide groove and abut against and drive the slider to slide synchronously relative to the fixed member, and make the slider more flexible and efficient when it rotates.

[0018] Optionally, the drive assembly includes a drive plate with holes in the housing. The drive plate can be connected to a drive component through the holes. The drive component drives the drive plate to slide within the receiving cavity. The drive plate can drive the first guide and the second guide to slide along the clearance groove.

[0019] By adopting the above technical solution, when the main body of furniture such as wall beds is flipped, the driving component can be driven to pull the driving plate to the corresponding position in the receiving cavity according to the tilt of the bed body. The first guide component is driven to slide along the axial direction of the fixed component, and the sliding component slides synchronously as a whole. At the same time, the driving plate can drive the second guide component to slide a certain distance relative to the fixed component. According to the contact or avoidance between the second guide component and the second guide groove, the support leg connected to the sliding component is driven to extend, retract and rotate synchronously relative to the bed frame.

[0020] Optionally, the drive plate is provided with a first multi-segment slide groove and a second multi-segment slide groove. The first guide member passes through the first multi-segment slide groove and can slide relative to the drive plate along the first multi-segment slide groove. The second guide member passes through the second multi-segment slide groove and can slide relative to the drive plate along the first multi-segment slide groove.

[0021] By adopting the above technical solution, the first multi-segment sliding groove on the drive plate enables the drive plate to synchronously drive the first guide member to slide relative to the fixed member along the direction of the avoidance groove in conjunction with the furniture body flipping structure. The first guide member and the sliding member are at their upper limits in the sliding direction. The first guide member drives the sliding member to slide relative to the fixed member, causing the support foot connected to the sliding member to move closer to and away from the furniture body frame. The second multi-segment sliding groove on the drive plate enables the drive plate to synchronously drive the second guide member to slide relative to the fixed member along the direction of the avoidance groove in conjunction with the furniture body flipping structure. This allows the second guide member to be limited or avoidance by the second guide groove on the sliding member, allowing the support foot connected to the sliding member to rotate or slide relative to the furniture body.

[0022] Optionally, the first multi-segment slide includes a first slide parallel to the direction of movement of the drive plate, a second slide connected to one end of the first slide, the second slide being a straight or curved slide on the drive plate that is not parallel to the direction of movement, a third slide connected to the end of the second slide away from the first slide, the third slide being parallel to the first slide, and the second multi-segment slide includes a fourth slide, a fifth slide, and a sixth slide, the second multi-segment slide and the first slide being arranged in parallel and corresponding manner, and the distance between the fourth slide and the first slide being greater than the distance between the sixth slide and the third slide.

[0023] By adopting the above technical solution, the drive plate slides in a vertical direction through the fixed component, limiting the first and second guide members to the walls of the first and second multi-segment sliding grooves, respectively. During the sliding of the drive plate, the first and second guide members avoid the multi-segment sliding grooves. The drive plate drives the first and second guide members to slide in a misaligned direction along the sliding direction of the drive plate, causing the first and second guide members to drive the sliding member to slide axially along the fixed component, thus bringing the support feet connected to the sliding member closer to or further away from the bed frame. The relative movement and cooperation between the second guide groove on the sliding member and the moving second guide member on the sliding member causes the sliding member to rotate on the fixed component, allowing the support feet connected to the sliding member to rotate relative to the support body for storage or support use.

[0024] Optionally, the cavity is equipped with a slide rail, and fixed rods are provided on both sides of the slide rail. A sliding roller is rotatably connected to the drive plate, and the fixed rods are fitted into the sliding rollers, allowing the sliding rollers to slide on the fixed rods.

[0025] By adopting the above technical solution, the drive plate is mounted on the fixed rod on the slide rail via sliding rollers, so that the drive plate can slide stably and accurately on the slide rail. Through the distance between the slide rail and the first guide and the second guide, the ends of the first guide and the second guide away from the sliding member are fitted into the first or second multi-segment slide groove of the drive plate, so that the drive member can fully drive the guide assembly to slide relative to the fixed member.

[0026] In summary, this application has at least the following beneficial effects:

[0027] 1. The entire mechanism and the frame of the main body of the furniture, such as the bed or desktop, are fixed in place by a box, allowing the support legs connected to the mechanism to be installed and connected to the main body of the furniture. The functional furniture flip-adjustment mechanism provides power to the drive component, which drives the guide component to slide relative to the fixed part. When the guide rail wall on the guide component and the sliding part is limited, the guide component drives the sliding part to slide synchronously on the fixed part, causing the support leg connected to the sliding part to extend and retract relative to the main body of the furniture. This allows the support leg to move closer to or further away from the main body of the furniture, preventing it from being easily blocked by the frame of the main body during subsequent rotation or storage, thus preventing it from becoming unusable. When the sliding direction of the guide rail and the sliding part is not in a straight line, the sliding part is squeezed by the guide component, causing it to rotate. The sliding part avoids the guide component through the guide rail, allowing the support leg connected to the sliding part to rotate relative to the main body of the furniture. When the support leg rotates to be parallel to the plane of the main body of the furniture, it is stored together, reducing the storage space of the furniture. Alternatively, the support leg can be rotated to form a certain angle with the plane of the main body of the furniture, allowing the support leg to stably support the main body of the furniture. By using two types of guide rails on the slider, the slider and guide assembly can make contact or avoid each other. Through a precise and stable mechanical adjustment structure, the support legs can be stored or used in sync with the main body of the furniture.

[0028] 2. Driven by the drive component, when the first guide member drives the slider to slide on the fixed member, the second guide member simultaneously drives the slider to slide along the clearance groove on the fixed member. The second guide member limits and abuts against the multi-segment guide groove, causing the second guide member to drive the slider to rotate. The multi-segment guide groove on the slider avoids the sliding of the second guide member, allowing the slider to rotate in a direction perpendicular to the sliding direction of the second guide member, thereby causing the support foot connected to the slider to rotate for storage or support.

[0029] 3. By setting the guide surface, the groove walls on both sides of the second guide groove can stably clamp the second guide member when the slider rotates, so that the second guide member can slide stably in the second guide groove and abut against and drive the slider to slide synchronously relative to the fixed member, and make the slider more flexible and efficient when it rotates.

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] In this embodiment, refer to Figure 1 and Figure 2 A controllable rotation and telescopic mechanism includes a box body 1, preferably a rectangular box body 1. The box body 1 is fixedly installed on the main body of furniture, such as the four corners of the frame of a bed board, using screws or other fasteners. The mechanism described in this application is provided at the two corners of the foot of the bed board. The box body 1 is hollow, forming a receiving cavity 2 for holding objects. An opening 3 is provided on the side of the box body 1 near the bed board, and the opening 3 is connected to the receiving cavity 2. A fixing member 4 is fixedly installed on the inner wall of the receiving cavity 2 away from the opening 3. A sliding member 5 is provided on the fixing member 4. The sliding member 5 can slide on the fixing member 4 along the setting direction of the fixing member 4. One end of the sliding member 5 can slide or rotate on the fixing member 4, and the other end passes through the opening 3 and the bed board frame and is fixedly connected to a support leg 6. (Refer to...) Figure 3 and Figure 4The sliding member 5 has a hollowed-out guide rail 8 and a guide component 7. The guide component 7 can pass through the guide rail 8, allowing the sliding member 5 to avoid relative rotation with the guide component 7. This allows the support leg 6 connected to the sliding member 5 to rotate relative to the bed board. The support leg 6 forms a certain angle with the bed board to support the bed board during use or when it is rotated and stored parallel to the bed board plane. When the sliding member 5 is limited and abutted by the guide component 7, the guide component 7 drives the sliding member 5 to slide relative to the fixed member 4, allowing the end of the sliding member 5 connected to the support leg 6 to extend away from the receiving cavity 2. This prevents the support leg 6 from hitting the bed board during rotation and becoming unusable. The guide component 7 is equipped with a drive component 9, which is connected to the flipping and adjustment mechanism of functional furniture such as wall beds. When the functional furniture is flipped for use or stored, the drive component 9 is driven synchronously. The drive component 9 can drive the sliding part 5 to slide or rotate relative to the fixed part 4 through the guide component 7, so that the use and storage state of the support leg 6 is consistent with the use state of the main body of the functional furniture. Through a precise and stable mechanical adjustment structure, the support leg 6 can be stored or used in sync with the main body of the furniture, improving the convenience and durability of the functional furniture.

[0042] In this embodiment, refer to Figure 3 The fixing member 4 is cylindrical and hollow along the axial direction, forming a fully conductive sliding channel 10. One end of the fixing member 4 is fixed to the inner wall of the receiving cavity 2 away from the opening 3, and the channel opening of the sliding channel 10 is aligned with the opening 3. A guide component 7 is provided on the sliding member 5. The sliding member 5 and the guide component 7 are fitted into the sliding channel 10, and the fixing member 4 is hollow along the axial direction, forming a relief groove 11. The relief groove 11 is conductive to the sliding channel 10. The guide component 7 in the sliding channel 10 can be embedded in the combined fixing member 4 through the relief groove 11, so that the guide component 7 can pass through the relief groove 11 and be installed with the drive component 9. The drive component 9 can drive the guide component 7 to slide along the relief groove 11, thereby causing the guide component 7 to drive the sliding member 5 to slide on the fixing member 4.

[0043] In this embodiment, refer to Figure 4Preferably, the sliding member 5 and the fixing member 4 have similar structures and their outer diameters are equal to the inner diameters of the sliding channel 10. The sliding member 5 is hollow in the axial direction to form an installation channel 12. The guide channel includes a transverse opening 81. Preferably, the transverse opening 81 is perpendicular to the axis of the installation channel 12 and is connected to the installation channel 12. The guide assembly 7 includes a first shaft 71 and a first guide member 72 connected to the first shaft in the first direction. The first shaft 71 is fitted into the installation channel 12. One end of the first guide member 72 is fixedly connected to the first shaft 71, and the other end passes through the transverse opening 81 and then through the clearance groove 11. The drive assembly 9 drives the first guide member 72 to slide in the axial direction of the fixing member 4. Since the direction of the transverse opening 81 is inconsistent with the sliding direction, the first guide member 72 abuts against the sliding member 5, causing the sliding member 5 to slide relative to the fixing member 4, thereby realizing the function of the support foot 6 connected to the sliding member 5 moving closer to or further away from the bed board. Furthermore, when the slider 5 rotates, the first guide 72 avoids the slider 5 from rotating by means of the transverse opening 81 being set in the same direction as the slider 5.

[0044] In this embodiment, refer to Figure 4 The guide rail 8 includes a transverse opening 81 and multiple guide grooves 82. The sliding member 5 has multiple guide grooves 82 hollowed out, which communicate with the mounting channel 12. The guide assembly 7 also includes a second shaft 73 and a second guide member 74 connected to the second shaft 73. The second shaft 73 is fitted inside the mounting channel 12. One end of the second guide member 74 is fixedly connected to the second shaft 73, and the other end passes through the multiple guide grooves 82 and then through the clearance groove 11. The drive assembly 9 drives the second guide member 74 to slide along the axis of the fixing member 4. Since the direction of the multiple guide grooves 82 forms a certain angle with the axis of the mounting channel 12 (preferably less than 45 degrees), when the second guide member 74 slides along the axis of the mounting channel 12, it abuts against the sliding member 5, causing the sliding member 5 to slide on the fixing member 4. Furthermore, the sliding member 5 is tubular, and multiple guide grooves 82 are formed on the outer surface of the tubular part, which makes it easy for the sliding member 5 and the second guide member 74 to misalign. The sliding member 5 is squeezed by the second guide member 74, causing it to rotate, and the sliding member 5 rotates in a direction away from the multiple guide grooves 82.

[0045] In this embodiment, refer to Figure 4The multi-segment guide groove 82 includes a first guide groove 821, a second guide groove 822, and a third guide groove 823. The first guide groove 821 is formed by an axially hollow structure on the sliding member 5. The end of the first guide groove 821 near the opening 3 is connected to the second guide groove 822. The orientation of the second guide groove 822 is at an angle of less than 45 degrees to the axial direction of the sliding member 5. The end of the second guide groove 822 away from the first guide groove 821 is connected to the third guide groove 823. The third guide groove 823 and the first guide groove 821 are arranged parallel to each other and are a certain distance apart in the horizontal direction. Initially, the second guide member 74 passes through the first guide groove 821. When the drive assembly 9 drives the second guide member 74 to slide, and the second guide member 74 slides synchronously with the first guide member 72, the second guide member 74 and the sliding member 5 generate relative displacement. The second guide member slides along the first guide groove 821 into the second guide groove 822 and abuts against the groove wall of the second guide groove 822. The second guide groove 822 is inclined to the left. The right side of the second guide member 74 abuts against and squeezes the sliding member 5. The sliding member 5 rotates relative to the fixed member 4. The second guide member 74 avoids the relatively rotating and relatively sliding sliding member 5 through the second guide groove 822, so that the sliding member 5 completes the function of rotating and sliding. When the second guide member 74 slides into the third guide groove 823, the third guide groove 823 rotates with the slider 5 and is set to correspond with the clearance groove 11. The second guide member 74 passes through the third guide groove 823 and the clearance groove 11, so that both the slider 5 and the fixed member 4 are engaged by the second guide member 74, maintaining the state between the slider 5 and the fixed member 4, preventing the slider 5 from rotating, and enabling the support foot 6 to provide stable support.

[0046] In this embodiment, refer to Figure 5 The curved surface of the second guide groove 822 forms a guide surface 13. By setting the guide surface 13, the groove walls on both sides of the second guide groove 822 can stably clamp the second guide member 74 when the sliding member 5 rotates, so that the second guide member 74 can slide stably in the second guide groove 822 and abut against and drive the sliding member 5 to slide synchronously relative to the fixed member 4, and make the sliding member 5 more flexible and efficient when it rotates.

[0047] In this embodiment, refer to Figure 6The drive assembly 9 includes a drive plate 91 and a drive member 92. Preferably, the box body 1 has a hole 14, which is located on one side of the box body 1 in the direction perpendicular to the fixing member 4. Preferably, the drive member 92 is rod-shaped and is connected to the drive plate 91 after passing through the hole 14. When the bed board is flipped by the functional furniture flipping adjustment mechanism, the drive member 92 can drive the drive plate 91 to move synchronously towards or away from the hole 14 in the receiving cavity 2. When the bed board is flipped along the flipping mechanism, it can synchronously drive the drive plate 91 to slide to the corresponding position in the receiving cavity 2 according to the tilt of the bed board, so that the drive plate 91 drives the first guide member 72 to slide relative to the fixing member 4. At the same time, the drive plate 91 can drive the second guide member 74 to slide a certain distance relative to the sliding member 5, thereby driving the support leg 6 connected to the sliding member 5 to synchronously extend, retract, and rotate relative to the bed board.

[0048] In this embodiment, refer to Figure 7 The drive plate 91 is provided with a first multi-segment slide groove 15 at the position corresponding to the first guide component 7, and the drive plate 91 is provided with a second multi-segment slide groove 16 at the position corresponding to the second guide component 74. The first guide component 72 passes through the first multi-segment slide groove 15 and can slide relative to the drive plate 91 along the first multi-segment slide groove 15. The second guide component 74 passes through the second multi-segment slide groove 16 and can slide relative to the drive plate 91 along the first multi-segment slide groove 15. The first multi-segment slide 15 includes a first slide 151, a second slide 152, and a third slide 153. The first slide 151 is set in a direction parallel to the sliding direction of the drive plate 91. One end of the first slide 151 is connected to the second slide 152. The second slide 152 is a straight or curved slide on the drive plate 91 that is not parallel to the direction of movement. Preferably, the second slide 152 is an oblique slide that is offset towards the first slide 151 at one end. The other end of the second slide 152 is provided with the third slide 153. The setting direction of the third slide 153 is parallel to the setting direction of the first slide 151, and the vertical distance between the first slide 151 and the third slide 153 is the distance that the sliding member 5 can slide relative to the fixed member 4. When the first guide member 72 passes through the first slide groove 151, the drive plate 91 slides towards the hole 14. The drive plate 91 smoothly avoids the first guide member 72 through the first slide groove 151. When the drive plate 91 continues to slide, the first guide member 72 and the groove wall of the second slide groove 152 limit each other, causing the first guide member 72 to slide relative to the fixed member 4 towards the opening 3. At this time, the second slide groove 152 avoids the first guide member 72, allowing the first guide member 72 to slide relative to the second slide groove 152 to the third slide groove 153. After the third slide groove 153 avoids the first guide member 72, the other end of the third slide groove 153 limits the first guide member 72, and the drive plate 91 stops sliding. The support foot 6 connected to the sliding member 5 moves away from the opening 3. Similarly, when the drive plate 91 slides away from the hole 14, the support foot 6 connected to the sliding member 5 moves closer to the opening 3.

[0049] In this embodiment, refer to Figure 7 The first multi-segment slide 15 and the second multi-segment slide 16 have similar structures and are arranged in parallel. The first slide 151 and the fourth slide 161 are parallel and of equal length. By reducing the length of the sixth slide 163, which is parallel to the third slide 153, the length of the second slide 152 is less than the length of the fifth slide 162 and they are parallel. When the first guide 72 enters the third slide 153 of the first multi-segment slide 15, the first guide 72 cannot support the sliding member 5 to continue sliding relative to the fixed member 4. Through the portion of the fifth slide 162 that is longer than the first multi-segment slide 15, the drive plate 91 can drive the second guide 74 to continue sliding relative to the sliding member 5, so that the second guide 74 can cooperate with the multi-segment guide grooves 82 on the sliding member 5 to complete the rotation of the sliding member 5 on the fixed member 4.

[0050] In this embodiment, refer to Figure 2 and Figure 8 Preferably, a slide rail 17 is provided along the sliding direction of the drive plate 91. One end of the slide rail 17 is fixed to the inner wall of the receiving cavity 2 with a hole 14, and the other end is fixed to the inner wall on the side opposite to the hole 14. Fixing rods 18 are provided on both sides of the slide rail 17, passing through the receiving cavity 2. Preferably, the drive plate 91 is rectangular, and four sliding rollers 19 are rotatably connected at the four corners of the drive plate 91. The sliding rollers 19 can be fitted into the fixing rods 18. The drive plate 91 is mounted on the slide rail 17 by the four sliding rollers and can slide on the fixing rods 18 by the sliding rollers 19, so that the drive plate 91 slides precisely and stably along the slide rail 17. When the drive member 92 pulls the drive plate 91 to slide within the receiving cavity 2, the slide rail 17 enables the drive plate 91 to maintain a contact driving relationship with the first guide member 72 and the second guide member 74, so that the drive plate 91 slides stably, causing the first guide member 72 to slide relative to the fixed member 4, and causing the second guide member 74 to slide relative to the fixed member 4 and the sliding member 5.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
