Figure 1 schematically illustrates a perspective view of a box securing structure 1000 provided according to a first embodiment of the present invention. As shown in Figure 1 , the box securing structure 1000 includes a box 100, a restraining strap 200, and an adjuster (also referred to as a limiter) 300. The box 100 can be, for example, any suitable type of carrier. In some embodiments, the box 100 can be a plastic box, a metal box, or the like for storing items. In some embodiments, the box 100 may be a pet box, pet carrier, pet bag, etc. for accommodating a pet. The box 100 may be in the shape of a cube, a rectangular parallelepiped, or other irregular shapes. The box 100 generally includes a bottom plate 101, a top plate 102, and side plates 103 positioned between the bottom plate 101 and the top plate 102. The distance between the top plate 102 and the bottom plate 101 of the box 100 defines the height H of the box 100.The side panels 103 may include a front panel 1031, a rear panel 1032, a left side panel 1033, and a right side panel 1034. In some embodiments, the case 100 may have a bilaterally symmetrical shape. In some embodiments, the case 100 may be equipped with a handle (not shown in FIG. 1 ). The handle may be mounted on the top panel 102 of the case 100, or connected to any two opposing side panels of the case 100. It should be noted that, unless otherwise specified or limited, directional terms such as "front," "rear," "left," and "right" in the embodiments of the present invention refer to the "front," "rear," "left," and "right" orientations of the seat 400 (see FIG. 2 ) when the case 100 is placed on the seat 400. Arrows F and B schematically indicate the "front" and "rear" directions, and arrows L and R schematically indicate the "left" and "right" directions. These directional terms are used solely to clarify the description of the embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention. Referring to Figure 2 , a seat 400 may be, but is not limited to, a seat for a vehicle, such as a car seat or an airplane seat. The seat 400 includes a seat portion 410 and a backrest portion 420. The front of the seat 400 is provided with, for example, two or more sockets 42 located between the seat portion 410 and the backrest portion 420 and spaced laterally (left-right). Each socket 42 may be a TSOFTX socket. Continuing with Figure 1 , the restraint strap 200 is attached to the box 100. The restraint strap 200 includes two connecting ends 22. These connecting ends 22 are located on the exterior of the box 100 and are provided with anchors 26. Each anchor 26 is designed to connect to an anchor point at any suitable location. Referring to Figure 2 , when the box 100 is placed on the seat 400, the bottom plate 101 of the box 100 is supported by the seat portion 410, and the rear side plate 1032 of the box 100 faces the backrest portion 420. The two connecting ends 22 of the restraint belt 200 are detachably connected to corresponding sockets 42 (the sockets 42 serve as anchor points), thereby connecting the box 100 to the seat 400. It will be understood that the anchors 26 are ISOFIX connectors. The adjuster 300 is connected to the restraint belt 200. The relative position of the adjuster 300 and the restraint belt 200 is adjustable to adjust the length of the restraint belt 200 between the adjuster 300 and the anchors 26.Thus, when the case 100 is placed on the seat 400 and each anchor 26 is connected to the corresponding socket 42, the length of the restraint strap 200 between the adjustment device 300 and the anchor 26 is adjusted, thereby tightening the restraint strap 200 connected between the case 100 and the socket 42. This allows the case 100 placed on the seat 400 to be effectively pulled by the tightened restraint strap 300, preventing it from slipping forward relative to the seat 400 and potentially falling. In some embodiments, the adjuster 300 can be an A-LOCK, a webbing adjustment device, or a Japanese buckle, as long as it can adjust and secure the length of the restraint strap 200. Referring to FIG. 1 , the adjuster 300 can be mounted on the case 100, and the restraint strap 200 can be passed through and locked by the adjuster 300. The restraint strap 200 may also include an adjustment end 21. The adjuster 300 may be located between the adjustment end 21 and each of the connection ends 22 of the restraint strap 200. A user can pull the adjustment end 21 in the S direction to shorten the portion of the restraint strap 200 located between the adjuster 300 and the anchor 26. It will be appreciated that when the portion of the restraint strap 200 located between the adjuster 300 and the anchor 26 is tensioned and no further pulling of the adjustment end 21 is required, the restraint strap 200 can be locked by the adjuster 300, thereby maintaining the portion of the restraint strap 200 located between the adjuster 300 and the anchor 26 in a tensioned state. It should be noted that the number of connection ends 22 of the restraint strap 200 is not limited to the two described above. In some embodiments, the restraint strap 200 may have multiple connection ends 22, each of which may selectively connect to one of two or more receptacles 42 with an anchor 26. Alternatively, in some embodiments, the restraint belt 200 may have more than two connecting ends 22, with multiple anchors 26 correspondingly configured for each of the multiple connecting ends 22. At least a portion of the multiple anchors 26 can be selectively connected to two or more of the plugs 42, while other anchors 26 can be removably connected to any other suitable anchor point. It is understood that to accommodate different types of anchor points, the type of anchor 26 is not limited to ISOFIX connectors. In some embodiments, the anchor 26 may be, for example, a hook, a buckle, or the like. FIG. 1 illustrates an exemplary embodiment of a restraint belt 200. The restraint belt 200, for example, includes a first sub-belt 210 and two second sub-belts 220, forming an overall Y-shape.The first end of the first sub-strap 210 corresponds to the adjustment end 21 of the restraint strap 200. The second end of the first sub-strap 210 is connected to the first ends of the two second sub-straps 220. The second ends of the two second sub-straps 220 correspond to the two connecting ends 22, each of which is provided with an anchor 26. Continuing with Figure 1, the adjuster 300 can be located at the bottom of the front side panel 1031 of the box 100. In other embodiments, the adjuster 300 can be located at the top of the front side panel 1031 or at another suitable location. The first sub-strap 210 passes through the adjustment end 300. The connecting ends 22 on each second sub-strap 220 extend rearward from the front side panel 1031 along the bottom of the box 100 to the rear side panel 1032, then extend upward along the rear side panel 1032, and finally extend outward from the box 100 at a predetermined height D1 of the rear side panel 1032 (this can also be referred to as the connecting ends 22 exiting the box 100 at the predetermined height). In some embodiments, the predetermined height D1 is not less than half the height H, i.e., D1 = NH / 2. In some embodiments, the predetermined height D1 may be close to or equal to the height H. Of course, in some embodiments, the predetermined height D1 may be less than half the height H. In some embodiments, for example, the predetermined height D1 may be greater than one-third or one-quarter the height H. Referring to FIG2 , when the box 100 is mounted on the seat 400, each connecting end 22 extending from the predetermined height D1 extends toward the rear and lower portion of the box 100 to allow each anchor 26 to connect with the corresponding latch 42. When the restraint strap 200 between the adjuster 300 and the anchor 26 is tightened, the restraint strap 200 effectively prevents the box 100 from rolling forward, ensuring that the box 100 is stably supported on the seat 400. In some embodiments, the rear side panel 1032 of the box 100 may be provided with a hard member 15. The hard member 15 may be made of a hard material, including but not limited to hard plastic, metal, etc. The hard member 15 has a support portion 151, which is positioned below or flush with the top plate 102. Each connection end 22 passes through the support portion 151 of the hard member 15 and then extends outward from the box 100. The height of the support portion 151 corresponds to a predetermined height D1. The hard member 15 can be attached to the rear side panel 1032 of the box 100 by any suitable means, as long as the support portion 151 can provide support for the restraint belt 200. The hard member 15 can be a solid member or a hollow member having a hollow channel.Referring to Figure 1 , when the hard member 15 is a solid member (e.g., a solid sheet), each connecting end 22 extends upward between the rear side panel 1032 and the hard member 15, passes around the support portion 151 of the hard member 15, and extends outward from the box 100. Referring to Figure 4 , when the hard member 15 has a hollow channel 150, each connecting end 22 of the restraining strap 200 enters the hollow channel 150 from the bottom, passes around the support portion 151 of the hard member 15, and extends outward. Referring to Figures 1 and 4 , in some embodiments, the upper edge of the hard member 15 forms the support portion 151. Referring to Figure 5 , in some embodiments, a downwardly extending notch 155 is formed at the upper edge of the hard member 15, with the lower edge of the notch 155 forming the support portion 151. Referring to Figure 6 , in some embodiments, the hard member 15 is provided with an aperture 153, the lower edge of which forms a support portion 151. Referring to Figure 7 , in some embodiments, the hard member 15 is provided with an opening 156, which is distal to the bottom plate 101 of the box 100. The opening 156 can be located above half the height of the rear side plate 1032 and extend outward, or extend outward from the rear side plate 1032 near the top plate 102. The connection ends 22 of the restraint straps 200 extend from the openings 156 toward the exterior of the box 100. In some embodiments, the hard member 15 can be embedded within the rear side plate 1032 without protruding outward relative to the rear side plate 1032. In some embodiments, the hard member 15 can be attached to the rear side plate 1032 and protrude outward relative to the rear side plate 1032. In some embodiments, a portion of the hard member 15 may be embedded within the rear side panel 1032, while another portion may protrude outward from the rear side panel 1032. In some embodiments, the rear side panel 1032 of the case 100 includes a covering layer 10321, and the hard member 15 is located outside the covering layer 10321. The hardness of the hard member 15 is greater than that of the covering layer 10321. The covering layer 10321 may be made of fabric, for example. Each connecting end 22 extends upward between the covering layer 10321 and the hard member 15 and extends from the support portion 151 of the hard member 15 to the exterior of the case 100. This embodiment does not impose any restrictions on the size and shape of the hard member 15. In some embodiments, the bottom of the hard member 15 may extend to the bottom plate 101 of the case 100. In some embodiments, the bottom of the hard member 15 may be higher than the bottom plate 101. In some embodiments, the hard member 15 may be located in the transverse middle of the rear side plate 1032 , and a width W of the hard member 15 may be smaller than a width of the rear side plate 1032 .In some embodiments, the hard member 15 may correspond to the size of the rear side panel 1032. In some embodiments, the hard member 15 may be positioned offset to the left or right of the rear side panel 1032. In some embodiments, two or more hard members 15 may be provided, symmetrically arranged bilaterally. The connection ends 22 of the restraint strap 200 are respectively passed through the support portions 151 of the corresponding hard members 15 and then extend outward from the case 100. Referring to Figures 1 to 3, an exemplary embodiment of an adjuster 300 is shown. The adjuster 300 is mounted on the bottom of the case 100, near the front side panel 1031. The adjuster 300, for example, includes a lock 310 disposed on the case 100. The lock 310 may include a housing 313, a locking member 312, a pivot 314, and a retaining spring 315. A locking member 312, a pivot 314, and a torsion spring 315 are mounted to a housing 313, which is mounted to the case 100. A locking channel 311 is formed within the housing 313, through which the restraining strap 200 passes. The restraining strap 200 (more specifically, the first sub-strap 210) enters the housing 313 at one end of the locking channel 311 and exits the housing 313 at the other end. The locking member 312 is mounted to the housing 313 via a pivot 314. A torsion spring 315 is mounted on the pivot 314 and connected between the housing 313 and the locking member 312. More specifically, the middle portion of the locking member 312 is pivotally connected to the housing 313 via the pivot 314. Referring to FIG. 3 , the first end 3121 of the locking member 312 serves as a locking end, forcing the second sub-strap 210 against the channel wall 3111 of the locking channel 311, thereby locking the restraining strap 200 in place. The torsion spring 315 is used to maintain the locking member 312 in the locked state shown in Figure 3. The first end 3122 of the locking member 312 serves as a pressing end, allowing the locking member 312 to rotate about the pivot 314, thereby releasing the lock of the first end 3121 of the locking member 312 from the first sub-strap 210. In some embodiments, the first end 3121 of the locking member 312 may have an arcuate surface for abutting the first sub-strap 210, and the arcuate surface may be provided with a protruding tooth. When the first end 3121 of the locking member 312 abuts the first sub-strap 210 against the channel wall 3111, the abutment of the protruding tooth against the first sub-strap 210 effectively prevents the first sub-strap 210 from moving.In some embodiments, the raised teeth on the curved surface can be configured as a ratchet structure. This allows the restraint strap 200 to be pulled via the adjustment end 21 to tighten the portion of the restraint strap 200 located between the adjuster 300 and the anchor 26, without pressing the second end 3122 of the locking member 312. Once the restraint strap 200 is adjusted into place, the adjustment end 21 is no longer pulled, and the adjuster 300 maintains tension on the portion of the restraint strap 200 located between the locking member 312 and the anchor 26. It will be appreciated that to release the connection between the anchor 26 and the socket 42, the second end 3122 of the locking member 312 is pressed, releasing the contact between the first end 3121 of the locking member 312 and the first sub-strap 210, thereby loosening the portion of the restraint strap 200 located between the adjuster 300 and the anchor 26. FIG. 8 schematically illustrates a box fixing structure 1000 according to a second embodiment of the present invention. The box fixing structure 1000 includes a box 100, a restraining strap 200, and an adjuster 300. Unless otherwise specified, the box 100 can be described in the first embodiment. For example, the box 100 includes a bottom panel 101, a top panel 102, and side panels 103. The side panels 103 include a front panel 1031, a rear panel 1032, a left panel 1033, and a right panel 1034. Unless otherwise specified, the restraining strap 200 can be described in the first embodiment. For example, the restraining strap 200 can include a first sub-strap 210 and two second sub-straps 220. The restraining strap 200 is Y-shaped overall. The first end of the first sub-strap 210 corresponds to the adjustment end 21 of the restraining strap 200, and the third end of the first sub-strap 210 connects to the first ends of the two third sub-straps 220. The second ends of the two second sub-straps 220 correspond to the two connecting ends 22, each of which is provided with an anchor 26. Unless there is a conflict, the adjuster 300 can refer to the adjuster 300 in the first embodiment. Referring to Figure 8 , the two connecting ends 22 of the restraint strap 200 extend from the front side panel 1031 to the left and right side panels 1033 and 1034, respectively. They then extend rearward along the left and right side panels 1033 and 1034, and extend outward from the box 100 at a predetermined height D2. The relationship between the predetermined height D2 and the box height H can be referenced to the relationship between the predetermined height D1 and the box height H described above. Referring to Figure 8 , in some embodiments, the adjuster 300 can be installed in the lateral center of the front side panel 1031, with the adjuster 300 higher than the bottom panel 101 of the box 100.The first sub-strap 210 corresponds to the front side panel 1031 of the case 100. The first ends of the two second sub-straps 220 are respectively connected to the second ends of the first sub-strap 210, and the second ends of the two second sub-straps 220 are both passed through the adjuster 300. In one embodiment, the adjuster 300 may include the lock 310 described in the first embodiment. The two second sub-straps 220 have a portion that overlaps and is located between the first end 3121 of the locking member 312 and the channel wall 3111 of the locking channel 311. When the locking member 312 is in the locked state, the locking member 312 presses the two overlapping second sub-straps 220 against the channel wall 3111 of the locking channel 311, thereby locking the position of the restraint strap 200. When the user pulls the adjustment end 21, the two second sub-straps 220 can slide simultaneously relative to the locking channel 311. Of course, in other embodiments, the adjuster 300 may also have other implementations. Referring to FIG. 8 , in some embodiments, the adjuster 300 includes left and right opposing openings 301 and 302, and the two connecting ends 22 can respectively pass through the adjuster 300 through the openings 301 and 302. Continuing with FIG. 8 , in some embodiments, the housing 100 can be provided with a guide structure 111 for guiding and supporting the restraining belt 200. The guide structure 111 defines a predetermined height D2. In some embodiments, the guide structure 111 can be provided on the side panels 103 of the housing 100. The guide structure 111 can include, for example, a groove-shaped structure 1101 and at least one stopper 1102 provided on the side panels 103. The groove-shaped structure can extend, for example, from the left side panel 1033 and the right side panel 1034 of the housing 100 to the rear side panel 1032 of the housing 100. At least some of the stoppers 1102 are located near the ends of the corresponding groove-shaped structures on the rear side panels 1032. The two connecting ends 22 extend outside the box 100 after passing through the corresponding stoppers 1102. Continuing with FIG8 , in some embodiments, the lateral width of the box 100 is greater than the lateral distance between the two sockets 42 on the seat 400. The lateral width W1 between the two connecting ends 22 at their respective locations outside the box 100 can be greater than the lateral distance between the two sockets 42. In FIG8 , the lateral width W1 generally corresponds to the width between the two stoppers 1102. In some embodiments, when the lateral width of the box 100 is less than the lateral distance between the two sockets 42, the two connecting ends 22 can extend outside the box 100 from the left and right panels 1033 and 1034, respectively. FIG9 illustrates a variation of the guide structure 111.In some embodiments, the guide structure 111 includes, for example, one or more connectors 1103 attached to the side panels 103. The connectors 1103 define a channel 110 for the restraint belt 200 to pass through. In some embodiments, the connectors 1103 can be made of metal, plastic, or other suitable materials. One or more connectors 1103 can be disposed on one or more of the front side panel 103K, the rear side panel 1032, the left side panel 1033, and the right side panel 1034, as needed. In some embodiments, the connectors 1103 can connect to the case 110 to form a closed loop. In some embodiments, the connectors 1103 can be hook-shaped or C-shaped. FIG10 illustrates another variation of the guide structure 111. For example, the guide structure 111 includes two connectors 1103 disposed on the rear side panel 1032 and spaced laterally apart. The two connecting ends 22 pass through corresponding engaging members 1103 before exiting the box 100. The two engaging members 1103 are, for example, symmetrically disposed on the rear side panel 1032. The lateral distance between the two engaging members 1103 corresponds to the lateral width W1. In some embodiments, the guide structure 111 may include, for example, a single engaging member 1103 disposed in the lateral middle of the rear side panel 1032. The two connecting ends 22 cross and pass through the channel 110 of the engaging member 1103 before extending diagonally toward the left. Figure 11 schematically illustrates a box fixing structure 1000 according to a third embodiment of the present invention. The box fixing structure 1000 includes a box 100, a restraining strap 200, and an adjuster 300. Unless otherwise specified, the box 100 may be described in the first embodiment. For example, the box 100 includes a bottom panel 101, a top panel 102, a front panel 1031, a rear panel 1032, a left panel 1033, and a right panel 1034. Unless otherwise specified, the restraint strap 200 can refer to the description of the first embodiment. For example, the restraint strap 200 can include a first strap 210 and two second straps 220. The restraint strap 200 is Y-shaped overall. The first end of the first strap 210 corresponds to the adjustment end 21 of the restraint strap 200, and the second end of the second strap 210 connects to the first ends of the two second straps 220. The second ends of the two second straps 220 correspond to the two connection ends 22, each of which is provided with an anchor 26. Unless otherwise specified, the adjuster 300 can refer to the adjuster 300 of the first embodiment. See Figure 11. In some embodiments, the adjuster 300 can be mounted on the front side of the top plate 102 of the box 100.The restraint straps 200 correspond to the top panel 102 and rear side panels 1032 of the box 100. The two connecting ends 22 extend from the top panel 102 toward the rear and lower portion of the rear side panels 1032. More specifically, the first sub-strap 210 is adjustably connected to the adjuster 300. The first ends of the two second sub-straps 220 can be connected to the second ends of the first sub-strap 210 above the top panel 102 or behind the rear side panels 1032. The second ends of the two second sub-straps 220 extend toward the rear and lower portion of the box 100 and can be connected to the corresponding plug-in doors 42 via anchors 26. In some embodiments, the entire rear side panels 1034 can be made of a rigid material. In some embodiments, the adjuster 300 can be positioned on the front side panels 1031, for example, near the top panel 102. Figure 12 schematically illustrates a box securing structure 1000 according to a fourth embodiment of the present invention. This box-fixing structure 1000 is a variation of the box-fixing structure 1000 provided in the third embodiment. Unless otherwise specified, the components and inter-component relationships of the box-fixing structure 1000 of this embodiment may be referred to the description of the second embodiment. The following primarily describes the differences between this embodiment and the second embodiment. Referring to Figure 12 , the restraining strap 200 forms an annular structure 201, within which the box 100 is restrained. The anchor 26 is located near the bottom of the box 100. More specifically, the restraining strap includes a first sub-strap 210 and two second sub-straps 220, a first sub-strap 230, and two fourth sub-straps 240. The first end of the third sub-strap 230 is connected to the first sub-strap 210, and the second end of the third sub-strap 230 is connected to the first ends of the two fourth sub-straps 240. The second ends of the two fourth straps 240 are connected to the two second straps 220, respectively, to form the annular structure 201 that restrains the case 100. The third sub-strap 230 and the two fourth sub-straps 240 are routed through the front panel 1031 and the bottom panel 101 of the case 100. The connection point between each fourth sub-strap 240 and the corresponding third sub-strap 230 is near the anchor 26. In some embodiments, the adjuster 300 may include the lock 310 of the first embodiment. The first and second sub-straps 210, 230 have overlapping portions located between the first end 3121 of the locking member 312 (see FIG. 3 ) and the channel wall 3111 of the locking channel 311. When the locking member 312 is in the locked state, the locking member 312 forces the overlapping first and third sub-straps 210, 230 to abut against the channel wall 3111 of the locking channel 311, thereby locking the restraint belt 200 in place.When the user pulls the adjustment end 21, the first sub-strap 210 and the third sub-strap 230 can simultaneously slide relative to the locking channel 311, causing the annular structure 201 to shrink and tightly embrace the box 100. Of course, in other embodiments, the adjuster 300 can also have other implementations. It should be noted that while in the above embodiment, the user manually operates the adjustment end 21 to tighten the restraint strap 200, the method for tightening the restraint strap 200 is not limited to this. For example, in some embodiments, the adjustment end 21 can be wound around a reel, and the restraint strap 200 can be tightened or loosened by electrically controlling the rotation direction of the reel. The box-securing structure provided by the embodiments of the present invention only needs to be able to adjust the length of the restraint strap 200 between the adjuster 300 and the anchor 26 so that the restraint strap 200 between the box 100 and the anchor point does not loosen. In some embodiments, the restraint strap 200 may not be provided with a dedicated adjustment end 21. In some embodiments, the first sub-strap 210 is also not required. The above embodiments describe the box-securing structure provided by the embodiments of the present invention. However, it should be noted that the box-fixing structure can also be provided as a carrying device. The following lists embodiments of the carrying device provided by the present invention and illustrates them with reference to Figures 13 to 53. For ease of understanding, arrow F in Figures 13 to 53 indicates forward direction, arrow B indicates rearward direction, arrow L indicates left direction, and arrow R indicates right direction. These directional terms are intended solely to clarify the description of the embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention. Fifth Embodiment: Figures 13 to 15 show perspective views of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided by the fifth embodiment. In Figures 13 and 14, the LATCH structure 300A is in use. In Figure 15, the LATCH structure 300A is in a non-use state (or stored state). As shown in Figures 13 to 15, the carrying device 1000A includes a body 100A, which may be, but is not limited to, a pet crate, pet carrier, or pet bag. When the carrying device 1000A is an animal carrying device, the body 100A has a carrying space for accommodating an animal. The body 100A can be a one-piece molded component, or it can be assembled from multiple components. In some embodiments, the body 100A can be divided into a bottom portion 101A and an upper portion 102A mounted above the bottom portion 101A. The bottom portion 101A can be made of a rigid material, for example, to provide support for the upper portion 102A. The upper portion 102A can include a fabric sheet or other material that encloses the carrying space.The back of the base 101A is provided with a LATCH structure 300A, which can be removably connected to the ISOFIX structure (or anchor structure) on the car seat. More specifically, the LATCH structure 300A includes, for example, at least one connector 31, each of which can engage with an ISOFIX connection point on the car seat. In this embodiment, the LATCH structure 300A includes two connectors 31. One end of each connector 31 is pivotally connected to the base 101A, for example, via a pivot (not shown). Each connector 31 rotates left and right about the pivot, allowing the LATCH structure 300A to have an engaged state and a non-engaged state. When the LATCH structure 300A is in the engaged state, each connector 31 pivots and extends outside the body 100A to a engaged position, allowing the other end of each connector 31 to connect with an ISOFIX connection point on the car seat. When the LATCH structure 300A is not in use, each connector 31 can pivot toward the body 100A to reach a non-use position (also called a storage position). The back of the base 101A has at least one accommodating space 1010 for accommodating the connector 31. In this embodiment, the back of the base 101A has two accommodating spaces 1010, located on the left and right sides of the back of the base 101A. The two accommodating spaces 1010 correspond to the two connectors 31. When the LATCH structure 300A is not in use, each connector 31 pivots to a storage position and is stored in the corresponding accommodating space 1010. For example, the outer side of the LATCH structure 300A after storage may be substantially flush with the outer side of the base 101A. Each connector 31 can be locked in the storage position by any suitable locking structure. The LATCH structure 300A may further include a spring for driving each connector 31 to rotate toward the use position. The spring is, for example, disposed between each connector 31 and the bottom 101A. When the LATCH structure 300A is in use, each connector 31 is released, and each connector 31 can automatically pop out due to the reaction force of the spring. In this embodiment, the two connectors 31 rotate horizontally in opposite directions to rotate from the storage position to the use position, or from the use position to the storage position. The rotation angle of the two connectors 31 is no more than 90 degrees. In some alternative embodiments, the two connectors 31 can rotate horizontally in the same direction to switch between the use position and the storage position.In some embodiments, the LATCH structure 300A may include two or more connectors 31, and the number of accommodating spaces 1010 is correspondingly two or more. The two or more connectors 31 can connect to one or more connection points of the ISOFIX structure of a car seat. Sixth Embodiment: Figures 16 and 17 show perspective views of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in a sixth embodiment. The carrying device 1000A includes a body 100A. When the carrying device 1000A is an animal carrying device, the body 100A has a carrying space for accommodating an animal. A connector 600 may be disposed between the body 100A and the car seat. The connector 600 includes the LATCH structure 300A, which can connect to the ISOFIX structure of the car. More specifically, the LATCH structure 300A includes, for example, at least one connector 31, each of which can connect to an ISOFIX connection point on the car seat. In this embodiment, the LATCH structure 300A includes two connectors 31. One end of each connector 31 is pivotally connected to the connector base 600, for example, via a pivot (not shown). Each connector 31 can be extended relative to or moved toward the connector base 600 by horizontally rotating in the same or opposite directions, enabling the LATCH structure 300A to have an active state and an inactive state (or a stowed state). The back of the connector base 600 may have a storage space 610. When the LATCH structure 300A is in the inactive state, each connector 31 can be stowed in the storage space 610 of the connector base 600. In this embodiment, the wooden body 100A may have a recessed space 110A, in which a rigid rod 112, such as a metal rod, may be disposed. The connecting base 600 is separate from the wooden body 100A. It includes a snap-fit ​​structure 220A, such as a hook. The snap-fit ​​structure 220A can be removably connected to the rod 112 on the wooden body 100A, allowing the wooden body 100A to be secured to the car seat via the detachable connecting base 600. When the support device 1000A is in use, the snap-fit ​​structure 220A is locked to the rod 112, and the connector 31 connects to the ISOFIX connection point of the car seat. The connecting base 600 also includes a release mechanism (not shown) for releasing the snap-fit ​​structure 220A from the rod 112. Once the snap-fit ​​structure 220A is released from the rod 112, the main body 100A can be separated from the connecting base 600.In some alternative embodiments, the connector 600 is slidably connected to the bottom 101A of the body 100A, allowing the connector 600 to have an in-use position and a storage position. For example, the bottom of the body 100A may be provided with a receiving cavity. When the connector 600 is in the storage position, the connector 600 is received in the receiving cavity and can be locked in the storage position. When the connector 600 is released, the connector 600 can extend horizontally backward from the receiving cavity and, when it reaches the in-use position, can be locked in the in-use position. The body 100A can then be connected to the ISOFIX structure of the car seat via the LATCH structure 300A on the connector 600. In some alternative embodiments, the connector 600 is pivotally connected to the bottom 101A of the body 100A, allowing the connector 600 to have an in-use position and a storage position. When the connector 600 is in the storage position, the connector 600 pivots to a position that aligns with the back or bottom surface of the body 100A. When the connector 600 is in the use position, it pivots to a horizontal position, extending rearward from the body 100A. The body 100A can then be connected to the LATCH structure 300A of the car seat via the LATCH structure 300A on the connector 600. Seventh Embodiment: Figures 18 to 21 show perspective views of a carrier 1000A (e.g., an animal carrier or other type of carrier) provided in the seventh embodiment. In Figures 18 and 19, the LATCH structure 300A is in use. In Figure 20, the LATCH structure 300A is in a non-use state (or stored state). The carrier 1000A includes a body 100A. When the carrier 1000A is an animal carrier, the body 100A has a carrying space for accommodating an animal. The bottom 101A of the body 100A has a LATCH structure 300A. The LATCH structure 300A is arranged on the back side of the bottom 101A. The LATCH structure 300A can be detachably connected to the ISOFIX structure on the car seat.

[0004] The LATCH structure 300A, for example, includes at least one connector 31, each of which can be engaged and secured with an ISOFIX connection point on a car seat. In this embodiment, the LATCH structure 300A includes two connectors 31. One end of each connector 31 is pivotally connected to the base 101A, for example, via a pivot (shown in the figure). Each connector 31 can rotate up and down about the pivot, allowing the LATCH structure 300A to have both an engaged and a disengaged state. When the LATCH structure 300A is in the engaged state, each connector 31 can be extended from the body 100A to the engaged position, allowing the other end of each connector 31 to connect with an ISOFIX connection point on the car seat. When the LATCH structure 300A is in the disengaged state, each connector 31 can be moved closer to the body 100A to reach a disengaged position (also known as a stowed position). For example, the back of the base 101A has at least one accommodating space 1010 for accommodating connectors 31. In this embodiment, the back of the base 101A has two accommodating spaces 1010 spaced apart in the left-right direction. Each accommodating space 1010 extends from the bottom surface of the body 100A. The two accommodating spaces 1010 are substantially the same height and can be parallel to each other. The two accommodating spaces 1010 correspond to two connectors 31. When the LATCH structure 300A is not in use, each connector 31 pivots to a storage position and is stored within the corresponding accommodating space 1010. For example, the outer side of the LATCH structure 300A, when stored, can be flush with the outer side of the base 101A, concave relative to the outer side of the base 101A, or convex relative to the outer side of the base 101A. The accommodating space 1010 can be integrally formed with the bottom 101A, or it can be separate accommodating spaces from the bottom 101A. When the accommodating space 1010 and the bottom 101A are integrally formed, the accommodating space 1010 is a semi-open space extending upward from the surface of the bottom 101A. Each connector 31 can be locked in the storage position by any suitable locking structure. The LATCH structure 300A may also include a spring for driving each connector 31 to rotate toward the use position. The spring is, for example, disposed between each connector 31 and the bottom 101A. When the LATCH structure 300A is in use, each connector 31 is released, and the reaction force of the spring automatically ejects the connector 31.In this embodiment, the two connectors 31 rotate vertically in a first direction (from top to bottom) to a use position, with a rotation angle of, for example, between 90 and 180 degrees. When the LATCH structure 300A is not in use, the two connectors 31 can be rotated vertically in a second direction (from bottom to top) to a storage position, where the two connectors 31 are stored in the accommodating space 1010. The first direction is opposite to the second direction. Eighth Embodiment: FIG22 shows a top perspective view of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in the eighth embodiment. FIG23 shows a perspective view of the carrying device 1000A placed on a car seat. FIG24 and FIG25 show bottom perspective views of the carrying device 1000A. The carrying device 1000A includes a main body 100A. When the carrying device 1000A is an animal carrying device, the main body 100A has a carrying space for accommodating an animal. The carrying device 1000A has two rails 120, which are arranged perpendicularly and parallel to the front or rear of the main body 100A. In this embodiment, both rails 120 are arranged on the rear of the main body 100A. The carrying device 1000A also includes a rigid rod 121, which is arranged on the same surface of the main body 100A as the rails 120. The ends of the rod 121 slidably engage with the two rails 120, enabling vertical movement within the rails 120. The rails 120 (e.g., within the rails 120) may be provided with a locking device (not shown in the figure) that locks the position of the rod 121. When the locking device is in the locked state, the rod 121 is locked by the locking device at a predetermined height on the rail 120 and cannot move up or down. When the carrying device is in the unlocked state, the locking device releases the lock on the rod 121, allowing the rod 121 to move up and down along the rail 120. The support device 1000A further includes a LATCH structure 300A, which can be removably connected to the ISOFIX structure on the car seat 900. More specifically, the LATCH structure 300A includes, for example, at least one connector 31, each of which can be connected to an ISOFIX connection point on the car seat. In this embodiment, the LATCH structure 300A includes two connectors 31.

[0005] The LATCH structure 300A further includes a male webbing 32 connected to the male connector 31. For example, the connector 31 includes a connecting hole 310A, and the webbing 32 passes through the connecting hole 310A, so that the connector 31 can slide along the webbing 32. A first end 321 of the webbing 32 is connected to the rod 121. A second end 322 of the webbing 32 can be passed through a locking mechanism 33 fixed to the back or bottom surface of the main body 100A and extend toward the front of the main body 100A. The locking mechanism 33, for example, is an A-locko. When the locking mechanism 33 is in the locked state, the webbing 32 is locked. Pulling the second end 322 of the webbing 32 allows the webbing 32 to be shortened between the first end 321 and the locking mechanism 33. However, moving the main body 100A forward does not allow the webbing 32 to be lengthened between the first end 321 and the locking mechanism 33. When the locking mechanism 33 is in the unlocked state, the webbing 32 is released. When the locking mechanism 33 is positioned near the front side of the bottom 101A of the body 100A, a guide structure 34 may be provided on the rear side of the bottom 101A of the body 100A. The second end 322 of the webbing 32 passes through the guide structure 34 and then through the locking mechanism 33. The guide structure 34 may, for example, include a recess 341 provided at the bottom of the body 100A and a support rod 342 mounted within the recess 341. The webbing 32 is routed around the support rod 342. When the support device 1000A is in use, the connector 31 is connected to the connection point of the ISOFIX structure of the car seat, and the locking mechanism 33 is locked. The webbing 32 can then be configured for tensioned use by moving the rod 121 upward. In this way, by connecting the male connector 21 to the ISOFIX structure of the car seat at two connection points, and by positioning the connection point between the first end 321 of the webbing 32 and the rod 121 away from the car seat surface, the body 100A can be subjected to tension from the angled portion of the webbing 32 between the first end 321 and the connector 21. This tension prevents the body 100A from rolling or spinning in the event of an unexpected vehicle collision. To detach the connector 31 from the ISOFIX structure of the car seat, the rod 121 is moved downward to loosen the webbing 32, making it easier for the LATCH structure 300A to detach from the ISOFIX structure of the car seat. Alternatively, the webbing 32 can be loosened by releasing the locking mechanism 33, making it easier for the LATCH structure 300A to detach from the ISOFIX structure of the car seat.In some embodiments, the body 100A is further provided with a storage space (not shown). This storage space can be located on the same surface as the track 120. This storage space can accommodate the connector 31 or the integral LATCH structure 300A. Ninth Embodiment: FIG26 shows a rear perspective view of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in the ninth embodiment. FIG27 shows a front perspective view of the carrying device 1000A. FIG28 shows a bottom perspective view of the carrying device 1000A. The carrying device 1000A includes a wooden body 100A. When the carrying device 1000A is used as an animal carrying device, the wooden body 100A has a storage space for accommodating the animal. At least one guide structure 131 and at least one locking mechanism 33 are located on the back of the wooden body 100A. The locking mechanism 33 is, for example, located near the bottom surface of the wooden body 100A, with the guide structure 131 being higher than the locking mechanism 33. The guide structure 131, for example, comprises a C-shaped member, and the locking mechanism 33, for example, is an A-lock. For example, there are two guide structures 131 and two locking mechanisms 33. The carrying device 1000A further comprises a LATCH structure 300A, which can be detachably connected to the ISOFIX structure on the car seat 900. More specifically, the LATCH structure 300A comprises, for example, at least one connector 31, each of which can engage with a connection point of the ISOFIX structure on the car seat. In this embodiment, the LATCH structure 300A comprises two connectors 31.

[0006] The LATCH structure 300A also includes a webbing 32 connected to the connector 31. The ends of the webbing 32 pass through corresponding guide structures 131 and locking mechanisms 33 before being connected to the two connectors 31. The middle portion 323 of the webbing 32 can be pulled by the user. When the locking mechanism 33 is in the locked state, the webbing 32 is locked. Pulling the middle portion 323 of the webbing 32 allows the webbing 32 to be shortened between the connector 21 and the locking mechanism 33, thereby tightening the webbing 32. However, moving the body 100A forward does not allow the webbing 32 between the connector 21 and the locking mechanism 33 to be lengthened. When the locking mechanism 33 is in the unlocked state, the webbing 32 is released. In some embodiments, the webbing 32 can be disconnected from the middle portion 323. An adjuster 34A may be provided on the webbing 32 to adjust its length. The adjuster 34A is, for example, located between the locking mechanism 33 and the connector 31. When the LATCH structure 300A is in use, the middle portion 323 of the webbing 32 can be looped around and secured to the headrest of the car seat. In the event of a collision, the body 100A can be prevented from twisting or rolling by securing it at the end of the car seat's headrest and at the two ISOFIX connection points. In an alternative embodiment, the body 100A includes a receiving space (not shown). The walls of the receiving space can be formed of a hard material. The receiving space can be located on the bottom surface of the body 100A and communicate with the outer surface of the body 100A. The body 100A can also include two extensions (not shown in the drawings of this embodiment; refer to the extension 14 in FIG. 29 of the tenth embodiment). Each extension extends upward from the bottom of the body 100A. The extension can be a semi-open channel or a hollow channel, with an upper opening near the top of the body 100A. The LATCH structure 300A is connected to the body 100A and includes a webbing 32. The webbing 32 extends within the accommodating space and the extension portion, and extends out of the body 100A through the upper opening of the extension portion. The LATCH structure 300A includes at least one connector 31 connected to the webbing 32. For example, the LATCH structure 300A includes two connectors 31. The connection between the two connectors 31 and the webbing 32 can be seen in FIG. 26 . The two connectors 31 are located at opposite ends of the webbing 32, and the middle portion of the webbing 32 extends out of the body 100A through the upper opening of the extension portion.When the LATCH structure 300A is in use, the connector 31 extends outside the accommodating space and connects to the ISOFIX connection point on the car seat. When the LATCH structure 300A is not in use, the connector 31 is disconnected from the ISOFIX connection point on the car seat and can be stored in the accommodating space. The accommodating space or the extension portion may also include a locking mechanism (e.g., A-lock) for locking or releasing the webbing 32. When the LATCH structure 300A is in use, the webbing 32 extending out of the upper opening is pulled to tighten the portion between the connector 31 and the locking mechanism, and the webbing 32 is locked by the locking mechanism. If the extension portion is a semi-open channel, a guide structure (e.g., similar to the guide structure 131 in FIG. 26 ) may be provided on the extension portion to maintain the webbing 32 in the extension portion and prevent it from falling out. Tenth Embodiment: FIG29 shows a rear perspective view of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) according to the tenth embodiment, with the LATCH structure 300A in use. FIG30 shows another rear perspective view of the carrying device 1000A, with the LATCH structure 300A in a non-use state (or stowed state). FIG31 shows a rear view of the carrying device 1000A shown in FIG30. FIG32 shows a front perspective view of the carrying device 1000A. The concepts of this second embodiment are similar to those of the ninth embodiment. The following mainly describes the differences between this embodiment and the ninth embodiment. The body 100A includes a storage space. The storage space may include two independent extensions 14, which extend from the bottom surface to the top surface of the body 100A. The extensions 14 may be hollow channels formed within the body or semi-open channels formed on the back surface of the body 100A, with top and bottom openings. In addition, two locking mechanisms 33 may be provided in the two extensions 14, for example, higher than the bottom surface of the body 100A. As described in the ninth embodiment, the locking mechanisms 33 may be, for example, A-lock = LATCH structures 300A, including a webbing 32. The ends of the webbing 32 enter the two extensions 14 through the top openings, pass downward through the corresponding locking mechanisms 33, and then connect to the two connectors 31. As described in the ninth embodiment, when the extensions are semi-open channels, a guide structure (e.g., similar to the guide structure 131 in FIG. 26 ) may be provided on the extensions. The webbing 32 can be maintained in the extension portion to avoid falling off. Of course, the guiding structure may not be provided.When the LATCH structure 300A is in use, the locking mechanism 33 is released, pulling the two connectors 31 out of the extension 14 and then connecting the two connectors 31 to the two connection points of the car seat's ISOFIX structure. The middle portion 323 of the webbing 32 is then pulled, shortening the length of the webbing 32 between the locking mechanism 33 and the connector 21, thereby tightening the webbing 32. The locking mechanism 33 locks the webbing 32, preventing the portion of the webbing 32 between the locking mechanism 33 and the connector 21 from lengthening and slackening. The middle portion 323 of the webbing 32 can be looped around and secured to the headrest of the car seat. In the event of a collision, the securement of the car seat headrest and the two connection points of the ISOFIX structure prevents the body 100A from twisting or rolling. When the LATCH structure 300A is not in use, the connector 31 is separated from the ISOFIX structure of the car seat. At this time, the connector 31 can be retracted from the bottom opening of the extension 14 into the extension 14 by pulling the middle portion 323 of the webbing. FIG33 shows a rear perspective view of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in the tenth embodiment. FIG34 shows a front bottom view of the carrying device 1000A, with the male buckle 351 and female buckle 352 of the magnetic fastening mechanism 35 engaged. FIG35 shows a rear bottom view of the carrying device 1000A, with the male buckle 351 and female buckle 352 of the magnetic fastening mechanism 35 separated. FIG36 shows a front view of the carrying device 1000A shown in FIG35. The carrying device 1000A includes a main body 100A. When the carrying device 1000A is an animal carrying device, the main body 100A has a carrying space for accommodating the animal. The body 100A is connected and secured to the ISOFIX structure of the car seat via the LATCH structure 300A. The LATCH structure 300A includes at least one connector 31, each of which can engage with the ISOFIX structure on the car seat. The LATCH structure 300A also includes at least one webbing 32, which connects the at least one connector 31 to the body 100A. In the figure, the LATCH structure 300A includes two connectors 31 and two webbings 32. The two webbings 32 are attached to the body 100A, allowing the LATCH structure 300A to be detachable from the body 100A. The webbings 32 are provided with a magnetic fastening mechanism 35.More specifically, the webbing 32 includes a first webbing segment 321A and a second webbing segment 322A. The first webbing segment 321A and the second webbing segment 322A define a ring-shaped structure that fits over the body 100A. One end of the first webbing segment 321A is adjustably connected to the second webbing segment 322A via an adjuster 324. One end of the second webbing segment 322A is connected to the connector 31. The adjuster 324 is located between the back of the body 100A and the connector 31. The other end of the first webbing segment 321A and the other end of the second webbing segment 322A are detachably connected via a magnetic fastening mechanism 35. The magnetic fastening mechanism 35 includes, for example, a male buckle 351 and a female buckle 352. The male buckle 351 connects to one of the first and second webbing segments 321A and 322A, while the female buckle 352 connects to the other of the first and second webbing segments 321A and 322A. The male buckle 351 has a protruding structure 3511, and the female buckle 352 includes a cavity 3520, which is designed to engage with the protruding structure 3511 of the male buckle 351. The protruding structure 3511 is provided with a groove 3510. The female buckle 352 also includes a locking mechanism 3521, which engages with the groove 3510 within the narrow cavity 3520. The groove 3510 can be a partially or fully annular structure. The female buckle 352 also has a release strap 353, which is operably connected to the locking mechanism 3521. Specifically, when the release strap 353 is pulled, the release mechanism 3521 is disengaged from the groove 3510 of the male buckle 351, allowing the male buckle 351 and female buckle 352 to further separate. The latching mechanism 3521 includes a magnetic device. The male buckle 351 (e.g., the protruding structure 3511) may also be equipped with a magnetic device. The magnetic devices of the male buckle 351 and the latching mechanism 3521 attract each other, further strengthening the fastening between the male buckle 351 and the female buckle 352. When the male buckle 351 and the female buckle 352 of the magnetic fastening mechanism 35 are fastened together, the webbing 32 wraps around the body 100A. The magnetic fastening mechanism 35 is located on the front of the body 100A. For example, the first webbing segment 321A of the webbing 32 extends from the top to the back of the body 100A, and the second webbing segment 322A extends from the bottom to the back of the body 100A. When the male buckle 351 and the female buckle 352 of the magnetic fastening mechanism 35 are separated, the body 100A and the LATCH structure 300A can be easily separated. 37 shows a rear plan view of a carrying device 1000A (eg, an animal carrying device or other types of carrying devices) provided in a twelfth embodiment.Figure 38 shows a front top view of the carrying device 1000A. Figure 39 shows a rear bottom view of the carrying device 1000A. Figure 40 shows a rear view of the carrying device 1000A. The carrying device 1000A includes a main body 100A. When the carrying device 1000A is an animal carrying device, the main body 100A has a carrying space for accommodating an animal. A fixing device 400A is provided on one side of the wooden body 100A. The fixing device 400A can be integrally formed with the wooden body 100A or detachable. The fixing device has a plurality of engaging grooves 41 arranged in a straight line on the outer side of the fixing device 400A. The engaging grooves 41 can be coupled to the handle 81 of the luggage case 800. The engaging groove 41 is further provided with an engaging structure (not shown). The engaging structure can accommodate handles 81 of varying thicknesses and / or widths. The engaging structure engages with the handle 81 to prevent the securing device 400A from separating from the handle 81. The secure connection between the securing device 400A and the handle 81 of the luggage case 800 allows the body 100A to be securely placed above the luggage case 800, effectively reducing any shaking of the body 100A and preventing separation. The carrying device 1000A also includes a LATCH structure 300A. The structure of the LATCH structure 300A and its connection to the body 100A can be referenced to the LATCH structures 300A and their connection to the body 100A described in the fifth to tenth embodiments. In this embodiment, the LATCH structure 300A is connected to the fixing device 400A. The connection method between the two can be referred to the connection method between the LATCH structure 300A and the body 100A in the ninth embodiment. Specifically, the LATCH structure 300A includes a webbing 32 and two connectors 31. The fixing device 400A can be equipped with a guide structure 131 and a locking mechanism 33. The ends of the webbing 32 pass through the corresponding guide structures 131 and locking mechanisms 33 before connecting to the two connectors 31. Each connector 31 can be connected to two connection points of the ISOFIX structure on the car seat. The middle portion 323 of the webbing 32 can be used by the user to lift. In addition, when the support device 1000A is fixed to the car seat, in addition to connecting to the ISOFIX structure through the connectors 31, the middle portion 323 of the webbing 32 can also be used to secure the body 100A to the car seat. When the carrying device 1000A is fixed to the luggage case 800 , the middle portion 323 of the webbing 32 can be passed over the lifting rod 81 .Twelfth Embodiment: FIG41 shows a rear top view of a carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in the thirteenth embodiment, with the male buckle 361 and female buckle 362 of the magnetic clasp mechanism 36 interlocked. FIG42 shows a front top view of the carrying device 1000A. FIG43 shows a side view of the carrying device 1000A, with the male buckle 361 and female buckle 362 of the magnetic clasp mechanism 36 interlocked. FIG44 shows a rear bottom view of the carrying device 1000A, with the male buckle 361 and female buckle 362 of the magnetic clasp mechanism 36 separated. FIG45 shows a side view of the carrying device 1000A, with the male buckle 361 and female buckle 362 of the magnetic clasp mechanism 36 separated. The carrying device 1000A includes a body 100A. When the carrying device 1000A is an animal carrying device, the body 100A has a carrying space for accommodating an animal. The carrying device 1000A also includes a LATCH structure 300A, which is connected to the ISOFIX structure of the car seat. For example, the LATCH structure 300A includes at least one connector 31, each of which can be connected to an ISOFIX connection point on the car seat. The body 100A and the LATCH structure 300A are quickly connected or disconnected via a magnetic fastening mechanism 36, making operation relatively convenient. The magnetic fastening mechanism 36 includes a male buckle 361 and a female buckle 362, one of which is located on the outer surface of the body 100A, and the other is located on the LATCH structure 300A. One or more magnetic fastening mechanisms 36 can be positioned between the body 100A and the LATCH structure 300A. Unless otherwise specified, the structures of the male buckle 361 and female buckle 362 of the magnetic fastening mechanism 36 can be similar to those of the male buckle 351 and female buckle 352 of the magnetic fastening mechanism 35 in the thirteenth embodiment. Specifically, the male buckle 361 has a protruding structure 3611, and the female buckle 362 includes a cavity 3620, which is designed to engage with the protruding structure 3611 of the male buckle 361. The protruding structure 3611 is provided with a groove 3610. The female buckle 362 also includes a locking mechanism 3621, which engages with the groove 3610 within the cavity 3620. The groove 3610 is a partially or fully annular structure. The female buckle 362 also has a release strap 363, which is operably connected to the locking mechanism 3621. Specifically, when the release strap 363 is pulled, the locking mechanism 3621 is disengaged from the groove 3610 of the male buckle 361, allowing the male buckle 361 and female buckle 362 to be further separated.For example, the two female buckles 362 are connected to the ends of the same release strap 363. This allows the two magnetic buckle mechanisms 36 to be released simultaneously when the release strap 363 is pulled. The locking mechanism 3621 may include a magnetic device, and the male buckle 361 (e.g., the protruding structure 3611) may also be provided with a magnetic device. The magnetic devices of the male buckle 361 and the locking mechanism 3621 attract each other, further strengthening the fastening between the male buckle 361 and the female buckle 362. In this embodiment, two magnetic buckle mechanisms 36 are provided between the body 100A and the LATCH structure 300A. The two female buckles 362 are provided on the outer side (e.g., the rear) of the body 100A, while the two male buckles 361 are provided on the LATCH structure 300A. The LATCH structure 300A includes two connectors 31, which are connected to the two male buckles 361 via two webbings 32. In some embodiments, the two male buckles 361 may be connected by a connecting strap 325. The two female buckles 362 are arranged parallel to each other on the outer side of the body 100A, away from the bottom surface of the body 100A. In some embodiments, the outer side of the body 100A may be provided with a sliding groove or rail 15A. This groove or rail 15A may be located on the same side of the body 100A as the two female buckles 362. The two female buckles 362 can slide along the sliding groove or rail 15A to adjust their relative positions. When the support device 1000A is in use, the LATCH structure 300A is connected to the body 100A via the magnetic buckle mechanism 36 and to the two connection points of the ISOFIX structure of the car seat via two connectors 31. The distance between the two female buckles 362 is, for example, greater than or equal to the distance between the two connection points of the ISOFIX structure of the car seat. Furthermore, when the carrying device 1000A is in use, the connecting strap 325 can be looped around and secured to the headrest of a car seat. When the car is struck, the two connection points at the end of the car seat headrest, secured in an ATSOFFTX structure, prevent the body 100A from twisting or rolling. Fourteenth Embodiment FIG46 shows a perspective view of the body 100A of the carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in the fourteenth embodiment, mounted on a luggage case 800 but not connected to the luggage case 800. FIG47 shows a top view of the body 100A and luggage case 800 shown in FIG46 . FIG48 shows a perspective view of the body 100A connected to the luggage case 800. Unless otherwise specified, the structure of the body 100A in this embodiment may refer to the description of the third embodiment.More specifically, when the carrying device 1000A is an animal carrying device, the body 100A has a carrying space for accommodating an animal. The outer side of the body 100A is provided with two buckles, such as female buckles 362. The two female buckles 362 can slide along the slide groove or rail 15A to adjust their relative position. The specific structure of the female buckles 362 is not described in detail. This embodiment also provides a magnetic buckle adjustment mechanism 500, which includes two buckles 51 and an adjustment mechanism 52. The two buckles 51 are, for example, male buckles, which are configured to engage with the female buckle 362. The male buckle may have an external protrusion 511, which is configured to engage with the cavity 3620 of the female buckle 362. The external protrusion 511 is provided with a groove 510, and the locking mechanism 3621 of the female buckle 362 can engage with the groove 510 within the cavity 3620. The female buckle 362 is further provided with a release strap 363, which is operably connected to the locking mechanism 3621. The groove 510 can be a partially or fully annular structure. The locking mechanism 3621 can include a magnetic device, and the male buckle (e.g., the protruding structure 511) can also be provided with a magnetic device. The magnetic devices of the male buckle and the release mechanism 3621 attract each other, further strengthening the fastening of the buckle 51 to the female buckle 362. Of course, in some alternative embodiments, the buckle 51 can be a female buckle, and the buckle of the body 100A± can be a male buckle. The two buckles 51 are connected by an adjustment mechanism 52. The adjustment mechanism 52 can further adjust the relative distance between the two buckles 51. The magnetic buckle adjustment mechanism 500 (the adjustment mechanism 52 or the two buckles 51) can be connected (e.g., removably connected) to the two parallel rods of the handle 81 of the luggage case 800. By adjusting the relative distance between the two buckles 51 through the adjustment mechanism 52, the distance between the two buckles 51 can be adapted to the width W of the handle 81 of different luggage cases. With reference to the description of the twelfth embodiment, the buckle 51 of the magnetic buckle adjustment mechanism 500 can be engaged with the buckle of the body 100A of the carrying device 1000A, and the engagement between the two can be released by the release strap 363, allowing the body 100A to be stably placed on the luggage case 800 or quickly detached from the luggage case 800. Fifteenth Embodiment: FIG49 shows a rear perspective view of the carrying device 1000A (e.g., an animal carrying device or other type of carrying device) provided in the fifteenth embodiment, with the male buckle 361 and female buckle 362 of the magnetic buckle mechanism 36 engaged. FIG50 shows a rear perspective view of the carrying device 1000A, with the male buckle 361 and female buckle 362 of the magnetic buckle mechanism 36 separated.The carrying device 1000A provided in the fifteenth embodiment is a variation of the carrying device 1000A provided in the twelfth embodiment. Unless otherwise specified, the structure of the carrying device 1000A provided in the fifteenth embodiment can refer to the structure of the carrying device 1000A provided in the thirteenth embodiment. The main difference between the fifteenth embodiment and the thirteenth embodiment is that the fifteenth embodiment omits the slide groove or rail 15A of the thirteenth embodiment. Instead, two female buckles 362 can be fixedly connected to the outer surface of the body 100A. FIG. 51 shows a rear perspective view of the carrying device 1000A provided in the sixteenth embodiment (e.g., an animal carrying device or other type of carrying device), with the male buckle 361 and female buckle 362 of the magnetic buckle mechanism 36 interlocked. FIG. 52 shows a rear perspective view of the carrying device 1000A, with the male buckle 361 and female buckle 362 of the magnetic buckle mechanism 36 separated. Figure 53 shows a front perspective view of the carrier device 1000A, showing the male and female snaps 361 and 362 of the magnetic closure mechanism 36 separated. The carrier device 1000A provided in the sixteenth embodiment is a variation of the carrier device 1000A provided in the fifteenth embodiment. Unless otherwise specified, the structure of the carrier device 1000A provided in the sixteenth embodiment can refer to the structure of the carrier device 1000A provided in the fifteenth embodiment. The following primarily describes the differences between the sixteenth and fifteenth embodiments. In this embodiment, the body 100A and the LATCH structure 300A of the carrier device 1000A are connected via four magnetic closure mechanisms 36, which are located away from the bottom surface of the body 100A. Furthermore, the four magnetic closure mechanisms 36 are arranged on multiple outer surfaces of the body 100A, for example, two magnetic closure mechanisms 36 are arranged on the back surface of the body 100A, and two magnetic closure mechanisms 36 are arranged on the opposing left and right sides of the body 100A. The female buckles 362 of the magnetic closure mechanism 36 are, for example, disposed on the body 100A. The left and right female buckles 362 can be connected to adjacent female buckles 362 via release strips 363. The male buckles 361 of the magnetic closure mechanism 36 are connected in pairs via the webbing 32. Each webbing 32 is connected to a connector 31, and the position of the connector 31 on the webbing 32 is adjustable. For example, the connector 31 includes a connection hole 310A, through which the webbing 32 passes, allowing the connector 31 to slide along the webbing 32. Of course, in other embodiments, the positions of the male buckles 361 and female buckles 362 on the body 100A and the LATCH structure 300A can be interchanged.This embodiment further enhances the connection stability between the body 100A and the ISOFIX structure of the vehicle seat by placing the magnetic fastening mechanism 36 on different outer surfaces of the support device 1000A, thereby preventing the body 100A from rolling over in the event of a vehicle collision. The technical features of the above-described embodiments can be combined in any manner.
