The following content will be described using the first card slot 10 to install a horizontal rod as an example.

[0022] When using the horizontal rod and the vertical rod connected by this structure on pets with different leg lengths, first pull out the locking pin 21 to separate the locking pin 21 from the positioning hole 11, and then rotate the vertical rod to change the height between the horizontal rod and the ground to better adapt to the pet. After the adjustment is completed, the locking pin 21 is inserted into the corresponding positioning hole 11 to fix the angle between the first component 1 and the second component 2, so that the horizontal rod and the vertical rod maintain the same state, and the adjustment process is simple and convenient.

[0023] As an improved specific embodiment, a mounting hole 22 is provided on the second component 2, and the locking pin 21 is arranged in the mounting hole 22. The locking pin 21 is a spring reset pin. When the pin rod is pulled out, the locking pin 21 is separated from the positioning hole 11; when the pin rod is released, the pin rod is inserted into the positioning hole 11.

[0024] Through the above technical solution, specifically, the locking pin 21 is fixed in the mounting hole 22 by a thread, can be automatically reset, and is more convenient to use.

[0025] As an improved specific embodiment, a first reinforcing rib 41 is provided in the first card slot 10 , and a second reinforcing rib 42 is provided in the second card slot 20 .

[0026] Through the above technical solution, the first reinforcing ribs 41 improve the structural strength of the first frame, and the second reinforcing ribs 42 improve the structural strength of the second frame.

[0027] As an improved specific embodiment, a first rotating hole 51 is provided on the first component 1, and the first rotating hole 51 is connected to the first card slot 10. A second rotating hole 52 is provided on the second component 2, and the second rotating hole 52 is connected to the second card slot 20. The connecting shaft 3 is located in the first rotating hole 51 and the second rotating hole 52. An operating hole 53 is provided on the second component 2, and the position of the operating hole 53 matches the position of the second rotating hole 52.

[0028] Through the above technical solution, the connecting shaft 3 passes through the first rotating hole 51 and the second rotating hole 52 to connect the first component 1 and the second component 2, and is operated through the operating hole 53, which is convenient to operate and improves assembly efficiency.

[0029] Specifically, the operating hole 53 is riveted and fixed to the vertical rod during subsequent processing.

[0030] As an improved specific implementation, the connecting shaft 3 links the first component 1 and the second component 2 by riveting.

[0035] Through the above technical solution, when connecting the first component 1 and the second component 2 by means of the bolt 31 and the nut 32, the bolt 31 is first placed in the first slot 10 and then passed through the first rotation hole 51. Then, the second rotation hole 52 of the second component 2 is aligned with the bolt 31 so that the bolt 31 passes through the second rotation hole 52. Then, the nut 32 is placed in the second slot 20 and preliminarily connected with the bolt 31. Then, a tool is inserted into the operating hole 53 to connect the bolt 31 and the nut 32, thereby completing the connection between the first component 1 and the second component 2.

[0036] The first component 1 and the second component 2 are connected by bolts 31 and nuts 32 and can be disassembled separately, thereby reducing replacement and maintenance costs.

[0037] As an improved specific implementation, the two ends of the connecting shaft 3 are respectively located between the first reinforcing rib 41 and the second reinforcing rib 42 .

[0038] Through the above technical solution, when the connecting shaft 3 adopts the bolt 31 and the nut 32, the end of the bolt 31 is located between the first reinforcing ribs 41. During the process of rotating the nut 32 to connect with the bolt 31, the bolt 31 has axial support, and there is no need to additionally fix the bolt 31, making installation easy and efficient.
