The difference between the present embodiment and the aforementioned embodiments is that, in the present embodiment, the connecting structure of the support part 915 is a rotating fastener 916, which is arranged in the support part 915 and partially exposed to the bottom surface (operation surface) 915B of the support part 915 for user operation; the animal carrier 92 is thereby stably installed to the cart body 91 by rotating the rotating fastener 916 to be fastened with the connecting structure at the bottom of the box 921 of the animal carrier 92 (further described below). Please refer to FIG. 9C and FIG. 9D, which show the appearance schematic diagram of the animal carrier 92 of the present embodiment from different perspectives. In the present embodiment, the animal carrier 92 comprises a box 921 and a bracket device 922, wherein the bracket device 922 comprises a first bracket 9221 and a second bracket 9222, which are arranged on the outer edge of the box 921 and have a contour corresponding to the outer edge of the box 921; the first bracket 9221 and the second bracket 9222 are connected with each other to form the bracket device 922, which is combined with the box 921 outside the box 921. In the present embodiment, the animal carrier 92 can not include a third bracket, so that the box 921 can be directly combined with the support part 915 of the cart body 91 with the bottom surface 921B; however, the present disclosure is not limited thereto. In other embodiments, the bottom of the box 921 of the animal carrier 92 can also be provided with a third bracket, i.e., the structure and composition of the animal carrier are the same as those of the aforementioned embodiments.In the present embodiment, the animal carrier 92 is formed with a connection structure 925 at the center of the bottom of the box 921. As shown in the drawings, the connection structure 925 is formed in a "cross" shape on the load-bearing surface 921A of the box 921, and is formed by the recess 9251 formed on the load-bearing surface 921A of the box 921 and the through portion 9252 penetrating the bottom of the box 921, so as to be formed in a "straight line" shape on the bottom surface 921B of the box 921. The animal carrier 92 is connected to the connection protrusion 9162 (shown in FIG. 9E) protruding from the top surface (support surface) 915A of the support portion 915 of the stroller body 91 through the through portion 9252 of the "straight line" structure, and is further buckled to stably combine with the support portion 915 of the stroller body 91. Please refer to FIG. 9F and FIG. 9G, which respectively show the exploded view and the partial cross-sectional view of the support portion 915 of the animal transport stroller 9 of the present embodiment, to illustrate the detailed structure and operation of the rotating buckle 916 of the stroller body 91. The rotating buckle 916 includes an inner rod 9163 penetrating the support portion 915, an outer tube 9164 sleeved outside the inner rod 9163, and an elastic element 9165 sleeved between the inner rod 9163 and the outer tube 9164. The inner rod 9163 is formed in a "T" shape in the longitudinal cross section, one end (bottom end) of which protrudes from the bottom surface (operation surface) 915B of the support portion 915 and is connected to the knob 916L. The knob 9161 is exposed to the bottom surface 915B of the support portion 915 to facilitate the rotating operation of the user. The other end (top end) of the inner rod 9163 is connected to the connection protrusion 9162 formed in a "straight line" shape, which can protrude from the top surface 915A of the support portion 915 for locking positioning of the box 921 of the animal carrier 92. In the present embodiment, the inner rod 9163 can be driven to rotate and move relative to the outer tube 9164 under the rotation of the knob 9161; that is, the inner rod 9163 can rotate relative to the outer tube 9164, and can move up and down relative to the outer tube 9164 to form a lifting structure together with the outer tube 9164. The elastic element 9165 provides a driving force for the inner rod 9163 to have a maximum relative displacement relative to the outer tube 9164. In the present embodiment, a sleeve 915L is formed in the support portion 915 corresponding to the position of the rotating buckle 916, which shields the elastic element 9165 of the rotating buckle 916. As shown in FIG. 9G to FIG. 91, the rotating buckle 916 includes a locking member 9163A, which can be, for example, a latch independent of the inner rod 9163, or a protrusion formed on the rod body of the inner rod 9163.The tube wall of the outer tube 9164 is formed with a positioning slot 9164A penetrating the tube wall, and the size of the locking member 9163A is adapted to the width of the positioning slot 9164A so as to be movable in the positioning slot 9164A. In the present embodiment, the positioning slot 9164A is approximately a "7-shaped" structure formed by a longitudinal slot 9164A1, a transverse slot 9164A2 and a positioning end 9164A3. As the inner rod 9163 moves upward in the outer tube 9164 from the lowest position, the locking member 9163A can correspondingly move upward in the longitudinal slot 9164A1 of the positioning slot 9164A, and be rotated under the driving of the knob 9161 to enter the transverse slot 9164A2 to continue to move transversely in the transverse slot 9164A2 under the rotation of the knob 9161, and finally enter the positioning end 9164A3 to be positioned therein. At this time, the moving stroke of the inner rod 9163 relative to the outer tube 9164 reaches the maximum, and when the locking member 9163A is positioned in the positioning end 9164A3, the inner rod 9163 is fixed relative to the outer tube 9164. Further, since the inner rod 9163 is fixedly connected to the knob 9161, when the user pushes the knob 9161 upward, the inner rod 9163 can be driven to move upward, and the locking member 9163A is also moved upward to the top end of the longitudinal slot 9164A1. Then, the user rotates the knob 9161 to drive the inner rod 9163 to rotate in the same direction, so that the locking member 9163A enters the transverse slot 9164A2 and further moves transversely to the end of the transverse slot 9164A2, so that the user cannot further rotate the knob 9161. At this time, the connecting block 9162 is transferred from the state of being located in the penetrating portion 9252 of the connecting structure 925 and not combined with the animal carrier 92 to the position of the recessed portion 9251. When the user stops applying force to the knob 9161, the inner rod 9163 can be reset due to the elastic force of the elastic element 9165.As shown in FIG. 9G and FIG. 9H, the top end of the inner rod 9163 of the rotating buckle 916 is a connecting protrusion 9162 in a "straight line" structure (i.e., the connecting protrusion 9162 shown in FIG. 9E), which can automatically extend out of the through portion 9252 on the bearing surface 921A of the box body 921 of the animal carrier 92 along the upward movement of the inner rod 9163 (i.e., the connecting protrusion 9162 is engaged in the through portion 9252 of the matching connecting structure 925 and protrudes above the bottom bearing surface 921A of the box body 921). When the user rotates the knob 9161 (e.g., by 90 degrees), the connecting protrusion 9162 can be synchronously rotated (e.g., also by 90 degrees) and stopped in the recess 9251 of the connecting structure 925, so that the box body 921 is fixedly positioned on the support portion 915, and the connection and cooperation of the animal carrier 92 and the stroller body 91 are completed. On the other hand, if the connection and cooperation of the animal carrier 92 and the stroller body 91 is to be released, the knob 9161 is pushed upward again to drive the inner rod 9163 to move upward and away from the recess 9251, and the knob 9161 is rotated (e.g., by 90 degrees) to synchronously rotate (e.g., also by 90 degrees) the connecting protrusion 9162 and enter above the through portion 9252, so that the inner rod 9163 reaches a movable position. Since the connecting protrusion 9162 is above the through portion 9252 and is not combined with the animal carrier 92, when the user stops applying force to the knob 9161, the inner rod 9163 can be driven to move downward by the elastic force of the elastic element 9165 (at this time, the connecting protrusion 9162 enters the through portion 9252), the locking of the box body 921 on the support portion 915 is released, so that the animal carrier 92 and the stroller body 91 are detached and separated, as shown in FIG. 91. Please refer to FIG. 10A and FIG. 10B, which show the appearance schematic diagram of the animal transport stroller 10 according to an embodiment of the present disclosure. The animal transport stroller 10 of the present embodiment comprises a stroller body 101 and an animal carrier 102, which is combined with the stroller body 101 in a detachable manner. In the present embodiment, the stroller body 101 has a similar structure and composition as the previous embodiments, including a stroller handle 1011, a storage layer 1012, a frame vertical rod 1013 connecting the stroller handle 1011 and the storage layer 1012, and a wheel member 1014, etc. The animal carrier 102 comprises a box body 1021 and a support device 1022.The difference between this embodiment and the aforementioned embodiments is that in this embodiment, the bottom outer side of the box body 1021 of the animal carrier 102 is formed with a connecting structure to stably link with the connecting structure on the top surface of the support portion 105 of the stroller body 101 in a track coupling manner. As shown in FIG. 10B, at least one pair of guide grooves 1053 is formed on the fixed base 1051 of the support portion 105 as the connecting structure, and a positioning portion 1054 is arranged on the fixed base 1051 near the front end.

Please refer to FIG. 10C, which shows a structural schematic diagram of the animal carrier 102 of this embodiment. In this embodiment, the box body 1021 of the animal carrier 102 is, for example, rectangular, which is formed by surrounding a bearing surface with four side walls, and has opposite long sides and opposite short sides; the bracket device 1022 of the animal carrier 102 includes a first bracket 10221 and a second bracket 10222, which are arranged around the outer edge of the box body 1021 and correspond to the outer edge of the box body 1021, and provide support for the box body 1021 to increase the bearing strength of the animal carrier 102. In this embodiment, a pair of guide rails 1023 is arranged on the outside of the bottom surface 1021B of the box body 1021 as the connecting structure, which protrudes from the bottom surface 1021B of the box body 1021 and extends along the long side direction of the box body 1021 on the bottom surface 1021B. In this embodiment, each guide rail 1023 is composed of a plurality of guide rail segments (three guide rail segments 1023A1-1023A3 in this embodiment) separated from each other, but the present disclosure is not limited thereto; in other embodiments, alternatively, the guide rail 1023 can also be formed as a single structure, depending on the actual application required. At least one positioning groove 1024 is formed on the bottom surface 1021B of the box body 1021, which is arranged between the pair of guide rails 1023 and at the front and rear ends (i.e., near the respective short sides of the box body 1021) on the bottom surface 1021B of the box body 1021. Please refer to FIG. 10D and FIG. 10E, which show side sectional schematic diagrams of the animal transport stroller 10 of this embodiment, for details of the operation key 1052 and the positioning portion 1054 of the support portion 105.The positioning portion 1054 includes a positioning protrusion 10541, an elastic element 10542, and a transmission pin 10543. The free end of the positioning protrusion 10541 has a guide surface 10541A for guiding the box 1021 so that the positioning groove 1024 of the box 1021 is guided by the guide surface 10541A and is driven in one direction to engage with the positioning protrusion 10541, so that the box 1021 cannot slide out of the positioning groove due to environmental disturbance. The other end of the positioning protrusion 10541 is connected to the elastic element 10542, which provides a restoring force for resetting the positioning protrusion 10541. The transmission pin 10543 connects the positioning protrusion 10541 and the operation key 1052. Specifically, as shown in FIG. 10E, the end of the operation key 1052 is formed with an inclined guide groove 1052A, and the transmission pin 10543 is located in the guide groove 1052A and can be displaced relative to the inclined surface of the guide groove 1052A. As shown in FIGS. 10D and 10E, when the animal carrier 102 is to be installed on the stroller body 101, a pair of guide rails 1023 (see FIG. 10C) on the bottom surface 1021B of the box 1021 of the animal carrier 102 are respectively engaged with a pair of guide grooves 1053 (FIG. 10B) of the fixed base 1051 of the support portion 105, and are guided by the guide grooves 1053 to be positioned. The free end of the positioning protrusion 10541 has a one-way guide surface 10541A, which can be pressed to drive the positioning protrusion 10541 to displace downward due to the movement of the box 1021 to the handle side, and after the box 1021 is positioned on the support portion 105, the positioning protrusion 10541 is driven by the elastic element 10542 to be forced into the positioning groove 1024 of the box 1021 to be locked. When the animal carrier 102 is to be detached from the stroller body 101, the user only needs to press the operation key 1052, which moves to the rear end under pressure, thereby driving the transmission pin 10543 of the positioning portion 1054 through the guide groove 1052A, thereby driving the positioning protrusion 10541 to move downward out of the positioning hole 1024, and releasing the locking of the animal carrier 102 on the support portion 105. After the locking of the animal carrier 102 and the stroller body 101 is released, the animal carrier 102 can be moved out of the support portion 105 by the relative movement of the guide rails 1023 in the guide grooves 1053. In this embodiment, a bottom plate is used as the fixed base 1051 of the support portion 105, and the guide grooves 1053 are formed on the bottom plate as the connecting structure for connecting the animal carrier 102 with the guide rails 1023 on the bottom of the box.In other embodiments, the support 105 can further be formed by a bottom plate and surrounding side plates connected to the bottom plate, and even further including a top plate connected to the surrounding side plates to form a closed drawer structure, and the guide slots can be selectively formed in the top plate, the bottom plate, or the side plates to stably engage with the corresponding connection structure of the animal carrier box 102.
