[0052] 1394 Specific Implementation of Connecting Members The present disclosure will be described in detail below with reference to the accompanying drawings. FIG1 shows a carrier 100 according to the present disclosure mounted on a base 200, which is mounted on a carrier vehicle 300. It should be noted that while the carrier 100 shown in the drawings is a pet carrier and the carrier vehicle 300 is a pet stroller, the present disclosure is not limited thereto. The carrier 100 according to the present disclosure can be used to carry animals or objects. The carrier vehicle 300 according to the present disclosure can be used to carry animals or objects in various applications, including but not limited to pet strollers, grocery carts, and camper vans. As shown in FIG3 through FIG7 , the carrier 100 according to the present disclosure includes a housing 110 and a connecting rod 120. The housing 110 is a generally rectangular container. However, it should be understood that the housing 110 can be of other shapes. In the embodiment shown in FIG2 , the housing 110 includes a plurality of ventilation holes 114 extending therethrough. These ventilation holes 114 can be distributed along the sidewalls of the housing 110 to enhance the ventilation of the housing 110. In the embodiment shown in Figures 15 and 16, the housing 110 can also include an anchoring joint 400 that can engage with corresponding fittings on a vehicle seat to secure the carrier 100 to the vehicle seat. The anchoring joint 400 can be moved between a position retracted within the housing 110 (see Figure 15) and a position extended from the housing 110 (see Figure 16). The housing 110 can include an anchoring joint operating member 410 for controlling the position of the anchoring joint 110 to extend from the housing 110. The housing 110 can be placed on the base 200 for more stable support, or connected to a carrier 300 or other supporting structure such as a rack. As shown, the connecting rod 120 according to the present disclosure is movably connected to the housing 110. The connecting rod 120 moves between the storage positions, and when in the engagement position, the connecting rod 120 can engage with the base 210 (see Figures 8 to 14B), thereby fixing the box body 110 to the base 200. The number of the connecting rods 120 can be one or more. This article takes two connecting rods 120 as an example, but Furthermore, since the structures of the two connecting rods 120 are identical, for ease of explanation, this article will primarily focus on the structure of one connecting rod 120. In the embodiment shown in Figures 3 to 7 , the connecting rod 120 is connected to the bottom 110 of the housing 110, thereby facilitating engagement between the connecting rod 120 and the connecting member 210 on the base 200. Furthermore, as shown in Figures 3 to 5 , the bottom 111 of the housing 110 can be provided with a housing recess 112, allowing the connecting rod 120 to be accommodated within the recess 112 when in the stowed position. This allows the housing bottom 111 to be planar. When the housing 110 is secured to the base 200, the bottom 111 can come into face-to-face contact with the upper surface of the base 200, providing more stable support for the housing 110. As shown in Figures 3 to 5, the bottom 111 of the housing 110 may also be provided with a relief recess 113, designed to facilitate the movement of the connecting rod 120 out of its storage position. For example, when the connecting rod 120 is in its storage position and accommodated within the housing recess 112, the shape and size of the housing recess 112 correspond to those of the connecting rod 120, making it difficult for a user to apply force to the connecting rod 120. By providing a relief recess 113 with an opening significantly larger than the diameter of the connecting rod 120, a user's finger can more easily apply force to the connecting rod 120, thereby facilitating its movement out of the storage position. The relief recess 113 may be in communication with the housing recess 112. However, the present disclosure is not limited thereto. The connecting rod 120 may be connected to other locations of the housing 110, such as a sidewall, as long as it is movable between an engaged position and a storage position. The connecting rod 120 can be directly or indirectly connected to the housing 110. In the embodiments shown in Figures 3 to 7, the connecting rod 120 can be movably connected to the housing 110 via a connecting mechanism. The connecting mechanism can include a pivot arm 130, whose first end 131 is connected to the connecting rod 120 and whose second end 132 is pivotally connected to the housing 110. As shown in Figure 7, the first end 131 of the pivot arm 130 is provided with an arm fixing hole, through which a screw, key, or other fastener can be passed to connect the pivot arm 130 to the connecting rod 120.Of course, if the pivot arm 130 and the connecting rod 120 are formed as one piece, so that the connecting rod 120 is formed into a U-shaped rod, it can be said that the connecting rod 120 is directly connected to the box body portion 110. In the embodiments shown in Figures 3 to 7, the connecting mechanism may further include a pivot arm fixing seat 140, which can be fixed to the box body bottom 111 of the box body portion 110, or fixed to other parts of the box body portion 110 as needed. As shown in Figures 3 to 7, the pivot arm fixing seat 140 is provided with a seat fixing hole, through which a screw, a key or other fastener can be passed to fix the pivot arm fixing seat 140 to the box body 110. The second end 132 of the pivot arm 130 can be pivotally connected to the pivot arm fixing seat 140, so that the pivot arm 130 is connected to the box body 110 via the pivot arm fixing seat 140. Since the connection portion between the connecting rod 120 and the box body 110 will wear out after long-term use, by providing the pivot arm 130 and the pivot arm fixing seat 140, the user only needs to replace the pivot arm 130 and the pivot arm fixing seat 140, without replacing the entire box body 110. = Next, a structure that can maintain the connecting rod 120 in the engaged position or the stored position will be described. In the embodiment shown in Figures 6 and 7, a pivot stopper 150 may be provided between the second end 132 of the pivot arm 130 and the pivot arm mounting base 140. The pivot stopper 150 may be configured to be immovable relative to the second end 132 of the pivot arm 130, rotatable relative to the pivot arm mounting base 140, and capable of being maintained in an engaged rotational position or a retracted rotational position relative to the pivot arm mounting base 140, thereby maintaining the connecting rod 120 in the engaged position or the retracted position. Of course, the pivot stopper 150 may also be configured to be immovable relative to the pivot arm mounting base 140, rotatable relative to the second end 132 of the pivot arm 130, and capable of being maintained in the engaged rotational position or the retracted rotational position relative to the second end 132 of the pivot arm 130. In the embodiment shown in FIG6 and FIG7 , connection holes may be formed in the second end 132 of the pivot arm 130, the pivot stopper 150, and the pivot arm fixing base 140, respectively. Screws, keys, or pins may be inserted through these holes to connect the second end 132 of the pivot arm 130, the pivot stopper 150, and the pivot arm fixing base 140 together. In another embodiment, the pivot stopper 150 may be integrally formed with one of the second end 132 of the pivot arm 130 and the pivot arm fixing base 140, thereby similarly achieving the technical effect of preventing the pivot stopper 150 from rotating relative to the other.As shown in FIG7 , the second end 132 of the pivot arm 130 is provided with a position-limiting spur groove 133, and the side of the pivot-limiting member 150 facing the pivot arm 130 is provided with position-limiting spur teeth 151. The position-limiting spur groove 133 and the position-limiting spur teeth 151 cooperate to prevent the pivot-limiting member 150 from rotating relative to the second end 132 of the pivot arm 130. Of course, the positions of the position-limiting spur groove 133 and the position-limiting spur teeth 151 can be interchanged. For example, the second end 132 of the pivot arm 130 can be provided with a position-limiting spur tooth 151, while the side of the pivot-limiting member 150 facing the pivot arm 130 is provided with a position-limiting spur tooth groove 133. This approach can also achieve the technical effect of preventing the pivot-limiting member 150 from rotating relative to the second end 132 of the pivot arm 130. As shown in FIG6 , the pivot-arm fixing base 140 is provided with a plurality of position-limiting helical tooth grooves 141. As shown in Figure 7, the side of the pivot stopper 150 facing the pivot arm mounting base 140 is provided with a plurality of beveled limiting teeth 152. The beveled limiting teeth 152 cooperate with the beveled limiting teeth grooves 141, allowing the pivot stopper 150 to rotate relative to the pivot arm mounting base 140 and remain in different rotational positions. The cooperation between the beveled limiting teeth 152 and the beveled limiting teeth grooves 141 ensures that the pivot stopper 150 remains in a fixed position relative to the pivot arm mounting base 140, preventing it from rotating arbitrarily. However, since the plurality of limiting beveled tooth grooves 141 and the plurality of limiting beveled teeth 152 are respectively located on the side surfaces of the pivot arm fixing base 140 and the pivot limiting member 150, and the contact surfaces between the two are contact bevels that are inclined relative to the axial direction of the pivot limiting member 150, when the pivot limiting member 150 is subjected to a driving force and tends to rotate about its axial direction, the contact bevels between the limiting beveled teeth 152 and the limiting beveled tooth grooves 141 will generate an interaction force along the axial direction. This interaction force causes the pivot limiting member 150 and the pivot arm fixing base 140 to tend to move away from each other. When the driving force applied to the pivot limiter 150 increases to a certain level, the interaction force between the limiting bevel teeth 152 and the limiting bevel tooth grooves 141 also increases to a certain level, eventually forcing the pivot limiter 150 and the pivot arm fixing base 140 to move away from each other until the limiting bevel teeth 152 disengage from the matching limiting bevel tooth grooves 141, thereby causing the pivot limiter 150 to rotate relative to the pivot arm fixing base 140.Then, after the pivot limiter 150 rotates a certain angle relative to the pivot arm mounting base 140, the limiting beveled tooth 152 may engage with another limiting beveled tooth groove 141, or the limiting beveled tooth 152 may again engage with the previously engaged limiting beveled tooth groove 141 (for example, after the pivot limiter 150 rotates 360 degrees relative to the pivot arm mounting base 140), thereby maintaining the pivot limiter 150 in a fixed rotational position relative to the pivot arm mounting base 140. A limiter reset device (not shown) may be provided on the opposite side of the pivot limiter 150 relative to the pivot arm mounting base 140 or at another suitable location. The limiter reset device is configured to press the pivot limiter 150 against the pivot arm mounting base 140, thereby ensuring that the limiting beveled tooth 152 engages with the limiting beveled tooth groove 141, thereby facilitating the pivot limiter 150 to maintain a fixed rotational position relative to the pivot arm mounting base 140. The position-limiting member resetting device can be an elastic member such as a spring, a pneumatic rod, or a hydraulic rod. The number of the plurality of position-limiting bevel slots 141 and the number of the plurality of position-limiting bevel teeth 152 can be the same or different. When the position-limiting bevel slots 141 and the position-limiting bevel teeth 152 are evenly distributed along the circumference and the number of the two is the same, the pivot position-limiting member 150 can be maintained at a plurality of different rotational positions relative to the pivot arm fixing seat 140, and the number of rotational positions is the same as the number of the position-limiting bevel slots 141 and the position-limiting bevel teeth 152. When the number of the position-limiting bevel slots 141 and the number of the position-limiting bevel teeth 152 are different, the pivot position-limiting member 150 can be maintained at one or several designated rotational positions relative to the pivot arm fixing seat 140. For example, the plurality of limiting bevel teeth 152 can be provided in two or two groups (see FIG. 7 ), and the plurality of limiting bevel tooth slots 141 can be provided in two groups (see FIG. 6 ). Each limiting bevel tooth slot 141 can engage with one of the limiting bevel teeth 152 or one group of limiting bevel teeth 152 , enabling the pivot limiter 150 to maintain two rotational positions relative to the pivot arm mounting base 140 . These two rotational positions can be an engaged rotational position and a stowed rotational position. When the pivot limiter 150 is maintained in the engaged rotational position relative to the pivot arm mounting base 140 , the connecting rod 120 is maintained in the engaged position. When the pivot limiter 150 is maintained in the stowed rotational position relative to the pivot arm mounting base 140 , the connecting rod 120 is maintained in the stowed position. Locking and Unlocking the Connecting Rod: Next, the structure that enables the connecting rod 120 to be locked and unlocked in the stowed position will be described. As shown in FIG. 15 to FIG. 24B , the housing portion 110 may be provided with a connecting rod locking member 170 that is movable between a locking position and a releasing position.The connecting rod locking member 170 can lock the connecting rod 120 in the stowed position when in the locked position (as shown in Figures 23A and 23B ) and release the connecting rod 120 when in the released position (as shown in Figures 24A and 24B ). As shown in Figures 15 and 16 , the connecting rod 120 is movably connected to the housing 110 via a pivot arm 130. The first end 131 of the pivot arm 130 is connected to the connecting rod 120, and the second end 132 is pivotally connected to the housing 110. Therefore, in the embodiment shown in Figures 17A to 20B , the connecting rod locking member 170 can lock and release the connecting rod 120 via the pivot arm 130. In one embodiment, as shown in Figures 19A to 20B , the second end 132 of the pivot arm 130 is provided with a pivot portion 134 that is pivotally mounted to the housing 110. The pivot portion 134 has a pivot connecting groove 134A. Correspondingly, the connecting rod locking member 170 is provided with a locking member protrusion 171 that can be inserted into the pivot connecting groove 134A. The pivot connecting groove 134A and the locking member protrusion 171 cooperate in such a manner that, when the connecting rod 120 is in the stored position, as shown in Figures 23A and 23B , when the connecting rod locking member 170 moves to the locked position, the locking member protrusion 171 of the connecting rod locking member 170 inserts into the pivot connecting groove 134A, locking the connecting rod 120 in the stored position. When the connecting rod locking member 170 moves to the unlocked position, as shown in Figures 24A and 24B , the locking member protrusion 171 of the connecting rod locking member 170 exits the pivot connecting groove 134A, releasing the connecting rod 120 and allowing the connecting rod 120 to move out of the stored position. It should be understood that the connecting rod locking member 170 according to the present disclosure can employ other methods for locking and unlocking the connecting rod 120. For example, in an embodiment in which the connecting rod 120 slides between a stored position and an engaged position, a loop may be provided at the end of the connecting rod 120, and the connecting rod locking member 170 may be provided with a hook. When the connecting rod 120 is in the stored position, the hook of the connecting rod locking member 170 may engage the loop of the connecting rod 120, thereby preventing the connecting rod 120 from leaving the stored position. When the connecting rod locking member 170 is operated to disengage its hook from the loop of the connecting rod 120, the connecting rod 120 can be removed from the stored position. In the embodiment shown in Figures 19A to 20B, a pivot arm reset device 135 may be provided between the housing 110 and the pivot arm 130, configured to tend to move the connecting rod 120 to the engaged position.Thus, once the connecting rod locking member 170 releases the connecting rod 120, the pivot arm reset device 135 will automatically move the connecting rod 120 from the storage position to the engaged position without requiring any user intervention. In the embodiments shown in Figures 17A to 18B and Figures 20A and 20B, the housing 110 may be provided with a pivot arm fixing seat 140, in which the pivot portion 134 of the pivot arm 130 can be pivotally received. As shown in Figures 20A and 20B, the pivot arm fixing seat 140 may be provided with a fixing seat opening slot 142, allowing the locking member protrusion 171 of the connecting rod locking member 170 to pass through the fixing seat opening slot 142 and be inserted into the pivot portion connecting slot 134A. In other embodiments, the housing 110 may not be provided with a pivot arm fixing seat 140, and the pivot portion 134 of the pivot arm 130 may be pivotally mounted directly on the housing 110. In the embodiment shown in Figures 20A and 20B , a pivot limiter 150 can be housed within the pivot portion 134 of the pivot arm 130. This limiter locking groove 153 can be defined therein, allowing the locking protrusion 171 of the connecting rod locking member 170 to pass through the fixing seat opening groove 142 and the pivot portion connecting groove 134A and be inserted into the limiter locking groove 153. It should be noted that the pivot limiter 150 in this embodiment may have the same or different structure as the aforementioned pivot limiter 150. Furthermore, the limiter locking groove 153 on the pivot limiter 150 may be formed by the gap between two adjacent limiter spur teeth 151. To facilitate user operation of the connecting rod locking member 170 from the locked position to the unlocked position, in the embodiments shown in Figures 15 to 24B , the housing 110 may further include a connecting rod operating member 160 that can be operated to move relative to the housing 110 between an initial position and a driven position. During movement from the initial position to the driven position, as indicated by the arrow in Figure 18B , the connecting rod operating member 160 can drive the connecting rod locking member 170 from the locked position to the unlocked position. In the embodiments shown in Figures 21 to 24B , the connecting rod locking member 170 may include a locking member driving post 172. Accordingly, the connecting rod operating member 160 may include an operating member driving slot 161 through which the locking member driving post 172 passes. The operating member driving slot 161 applies a force to the locking member driving post 172, enabling the connecting rod operating member 160 to drive the connecting rod locking member 170. In this embodiment, the movement direction of the connecting rod operating member 160 is perpendicular to the movement direction of the connecting rod locking member 170. In order to change the movement direction, a driving inclined surface 161A can be provided on the operating member driving groove 161.As shown in Figures 21 to 24B , the driving slope 161A can be configured such that, during the movement of the connecting rod operating member 160 from the initial position to the driving position as indicated by the arrow in Figure 18B , the driving slope 161A can exert a force on the locking member driving post 172 to drive the connecting rod locking member 170 from the locked position to the unlocked position. It should be noted that in the embodiment shown in Figures 21 to 24B , the operating member driving slot 161 is in the shape of a right triangle, with the hypotenuse of the right triangle forming the driving slope 161A. Therefore, during the process of the connecting rod operating member 160 returning from the driven position to the initial position, the operating member driving groove 161 does not exert any force on the locking member driving post 172. In other words, there is no interaction between the operating member driving groove 161 and the locking member driving post 172. Consequently, the connecting rod operating member 160 does not drive the connecting rod locking member 170 from the unlocked position to the locked position, and the connecting rod operating member 160 is not affected by the connecting rod locking member 170 when returning from the driven position to the initial position. This design has the advantage that after the connecting rod operating member 160 drives the connecting rod locking member 170 to the unlocked position, the connecting rod operating member 160 can return to the initial position regardless of whether the connecting rod locking member 170 has returned to the locked position. This prevents the connecting rod operating member 160 from being unable to return to the initial position due to the influence of the connecting rod locking member 170 and protruding from the housing 110. In this case, to enable the connecting rod locking member 170 to move to the locked position, a locking member reset device (not shown) can be provided. The reset device is configured to tend to move the connecting rod locking member 170 to the locked position. The reset device can be an elastic member such as a spring, a pneumatic rod, or a hydraulic rod. This allows the connecting rod locking member 170 to automatically move to the locked position without user intervention. The reset device also helps ensure that the connecting rod locking member 170 locks the connecting rod 120 in the stowed position. In another embodiment, the operating member drive slot 161 can be formed as an oblique, elongated slot. When the connecting rod operating member 160 moves between the initial position and the driven position, the operating member drive slot 161 can exert a force on the locking member drive post 172, thereby driving the connecting rod locking member 170 to move between the locked position and the unlocked position accordingly. In the embodiment shown in Figures 21 to 24B , the housing 110 may be provided with a limiting boss 115, and the connecting rod operating member 160 may be provided with an operating member limiting groove 162 that cooperates with the limiting boss 115. The cooperation between the limiting boss 115 and the operating member limiting groove 162 controls the movement of the connecting rod operating member 160 between the initial position and the driven position.Of course, the positions of the limiting protrusion 115 and the operating member limiting groove 162 can be interchanged. For example, the operating member limiting groove 162 can be provided on the housing 110, and the limiting protrusion 115 can be provided on the connecting rod operating member 160. This approach can also achieve the technical effect of controlling the movement of the connecting rod operating member 160. As shown in Figures 21 to 24B, an operating member reset device 163 can be provided between the housing 110 and the connecting rod operating member 160, configured to tend to move the connecting rod operating member 160 to its initial position. Of course, the present disclosure is not limited to this. In other embodiments, the connecting rod operating member 160 may not be required, and other methods may be used to drive the connecting rod locking member 170 between the locked position and the released position. For example, the connecting rod locking member 170 may have an operating portion exposed from the housing 110, through which the user can directly drive the connecting rod locking member 170 between the locked position and the released position. As shown in Figures 12 to 14B , the carrier 100 can be placed on the base 200. Furthermore, the base 200 according to the present disclosure can be provided with a connecting member 210 that can engage with the connecting rod 120 on the carrier 100, as described above, thereby securing the carrier 100 to the base 200. Figures 8 to 14B illustrate a first embodiment of the coupling between the carrier 100 and the base 200 according to the present disclosure. As shown in Figures 8 to 11B , the base 200 is provided with a connecting groove 220 into which the connecting rod 200 can enter. The position of the connecting groove 220 can correspond to the position of the connecting rod 200 in the engaged position. The number of connecting grooves 220 can be equal to or greater than the number of connecting rods 200. The connecting member 210 can be disposed in the base 200 and can move between a blocking position and a non-blocking position. As shown in Figures 13A and 13B , when the connecting member 210 is in the blocking position, it is partially exposed from the connecting groove 220, thereby preventing the connecting rod 120 located in the connecting groove 220 from leaving the connecting groove 220. As shown in Figures 14A and 14B , when the connecting member 210 is in the non-blocking position, it moves away from the connecting groove 220, thereby allowing the connecting rod 120 to enter and exit the connecting groove 220. In the embodiment shown in Figures 8 to 11B , the base 200 may be provided with a base release member 230 that is configured to be operated to drive the connecting member 210 to the non-blocking position.The base release member 230 can directly connect to and drive the connecting member 210, or it can indirectly drive the connecting member 210 via an intermediate member. In the embodiments shown in Figures 9A to 11B and 13A to 14B, the base 200 can be provided with a connecting member reset device 212, which is configured to tend to move the connecting member 210 to a blocking position. Thus, after the connecting rod 200 enters the connecting groove 220, the connecting member 210 can continuously prevent the connecting rod 120 located in the connecting groove 220 from leaving the connecting groove 220, thereby preventing the carrier 100 from accidentally detaching from the base 200. Furthermore, after a user operates the base release member 230 to move the connecting member 210 to the unblocking position, the connecting member 210 can be moved to the blocking position under the action of the connecting member reset device 212 without requiring any user operation. In the embodiment shown in Figures 10, 11A, and 11B, the end of the connecting member 210 may be provided with an inclined connecting member surface 211. This is configured so that the force exerted on the inclined connecting member surface 211 by the connecting rod 120 when entering the connecting groove 220 can drive the connecting member 210 to an unblocked position. Thus, when the user places the vehicle 100 on the base 200, the connecting rod 120 can easily enter the connecting groove 220, without the user having to move the connecting member 210 to an unblocked position. Figures 25A to 25E illustrate a second embodiment of the combination of a vehicle 1300 and a base 1390 according to the present disclosure. These diagrams schematically illustrate a traveling device 13 according to the present disclosure in various views. As shown in Figures 25A and 25B, the traveling device 13 includes the vehicle 1300 and the base 1390. The carrier 1300 can be constructed in a manner similar to the previous embodiment, including a housing 1310 and carrying handles 1330 pivotally and detachably connected to opposite sides of the housing 1310. In this embodiment, the carrier 1300 also includes a pair of connecting rods 1314 connected to the outer bottom of the housing 1310, through which the carrier 1300 can be mounted to the base 1390. In this embodiment, the housing 1310 includes a pair of recesses 1312 formed on the outer bottom 1311 and an actuating portion 1313 located in the center of the outer bottom 1311. The recesses 1312 are configured to receive the pair of connecting rods 1314 therein. Preferably, the connecting rods 1314 can be U-shaped and pivotally connected to the housing 1310, with their ends positioned within the respective recesses 1312.Referring now to Figures 25B and 25C , the base 1390 includes a pair of connecting grooves 1392 corresponding to the pair of connecting rods 1314 of the carrier 1300. On the inner surface of each connecting groove 1392, the base 1390 includes a pair of exposed connecting members 1394. Alternatively, only one connecting member 1394 may be present in each connecting groove 1392. Each connecting member 1394 may be, for example, a hook or claw having an opening that allows the connecting rod 1314 to enter and be loaded therein. Each connecting groove 1392 may have an inclined surface for guiding the corresponding connecting rod 1314. On its top surface 1391, the surface that contacts the outer bottom 1311 of the housing 1310, the base 1390 includes a centrally located actuating portion 1393. This actuating portion 1393 corresponds to the actuating portion 1313 located centrally on the outer bottom 1311. Preferably, the actuating portion 1313 located centrally on the outer bottom 1311 of the carrier 1300 may be recessed to cover a trigger mechanism for the connecting rod 1314, and the actuating portion 1393 located centrally on the top surface 1391 of the base 1390 may be a post. Referring to Figures 25D and 25E , respectively, the disconnection and connection of the carrier 1300 to the base 1390 in this embodiment are illustrated. As described above, the carrier 1300 is detachably connected to the base 1390, and a pair of connecting rods 1314 are connected to the outer surface of the housing 1310. As shown in FIG25D , the connecting rods 1314 can be accommodated in corresponding recesses 1312 on the outer bottom 1311 of the carrier 1300. When the carrier 1300 is positioned on the base 1390 for connection, the trigger mechanism within the carrier's actuating portion 1313 is pressed and triggered by the actuating portion 1393, causing the two connecting rods 1314 to pivot out of their corresponding recesses 1312. As shown in FIG25E , the connecting rods 1314 can be guided along the inclined surfaces of the corresponding connecting grooves 1392, passing through the openings and engaging with the corresponding connecting members 1394. Thus, through the engagement of the connecting rods 1314 with the connecting members 1394, the carrier 1300 can be stably attached to the base 1390. The base 200 according to the present disclosure can be mounted not only on the vehicle 300 but also on a vehicle seat. FIG26 and FIG27 illustrate an embodiment of the base 200 for a vehicle seat (not shown). In this embodiment, the base 200 may also be provided with a connecting member 210 and a connecting groove 220 .The connecting member 210 and connecting groove 220 in this embodiment can be the same as or different from the connecting member 210 and connecting groove 220 described above with reference to Figures 8 to 14B , as long as the connecting member 210 can engage with the connecting rod 120 on the carrier 100 and the connecting groove 220 can accommodate the connecting rod 200. In the embodiment shown in Figures 26 and 27 , the base 200 can be provided with a base release 230 that is operable to actuate the connecting member 210. As shown in Figures 26 and 27 , the base 200 can be provided with an anchoring joint 400 that can engage with a corresponding fitting on a vehicle seat to secure the base 200 to the vehicle seat, thereby securing the carrier 100 mounted on the base 200 relative to the vehicle seat.
