Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0026] A foldable and foldable axle for a workshop auxiliary vehicle comprises: a left axle rod 1, a right axle rod 11 is installed on the right side of the left axle rod 1, and a wheel hub 12 is provided at the left end of the left axle rod 1 and the right end of the right axle rod 11;

[0027] A slot 13 is provided on the right side wall of the left bridge rod 1, and a movable slot 14 is provided on the left side wall of the right bridge rod 11;

[0028] A connecting structure 2 is installed on the movable groove 14, and the connecting structure 2 includes a threaded sleeve 21. The threaded sleeve 21 is movably installed on the outer wall of the left end of the right bridge rod 11 through a thread. A circular groove 22 is opened on the inner wall of the threaded sleeve 21. An insert block 23 is slidably installed on the inner side of the movable groove 14, and a push block 24 is integrally formed on the outer wall of the insert block 23. The right end of the left bridge rod 1 and the left end of the right bridge rod 11 are movably connected through a hinge 25. A threaded sleeve 21 is arranged on the outer side of the left bridge rod 1 and the right bridge rod 11. The threaded sleeve 21 can be threadedly connected to the outer side of the connection between the left bridge rod 1 and the right bridge rod 11, so as to fix the left bridge rod 1 and the right bridge rod 11 together. In the process of movement of the threaded sleeve 21, the cooperation of the circular groove 22 and the push block 24 can drive the insert block 23 to be inserted into the slot 13 from the movable groove 14, so as to further strengthen the connection strength between the left bridge rod 1 and the right bridge rod 11, which is more practical.

[0029] Furthermore, a limiting structure 3 is installed on the left bridge rod 1 and the right bridge rod 11, and the limiting structure 3 includes a first connecting block 31, the first connecting block 31 is fixedly connected to the bottom surface of the right bridge rod 11, and the bottom surface of the left bridge rod 1 is fixedly connected to a second connecting block 32, and the second connecting block 32 is threadedly connected to a bolt 33. The threaded sleeve 21 is reset to the right bridge rod 11, and the fixed connection between the left bridge rod 1 and the right bridge rod 11 can be released. Then, the right bridge rod 11 is moved and flipped through the hinge 25, so that the wheel hubs 12 on the left bridge rod 1 and the right bridge rod 11 fit together. At the same time, the first connecting block 31 will be inserted on the inner side of the second connecting block 32, and the bolt 33 is rotated at this time. The bolt 33 passes through the first connecting block 31 and the second connecting block 32. The left bridge rod 1 and the right bridge rod 11 can be stored and fixed through the cooperation of the limiting structure 3 and the hinge 25, thereby reducing space occupancy and facilitating storage.

[0030] Furthermore, the interiors of the slot 13 and the movable slot 14 are connected, and the insert block 23 in the movable slot 14 can be inserted into the slot 13 so that the insert block 23 is located between the slot 13 and the movable slot 14, and the left bridge rod 1 and the right bridge rod 11 can be connected together on the inside.

[0031] Furthermore, the cross section of the insert block 23 matches the cross section of the slot 13 , and the left end of the insert block 23 can be inserted into the slot 13 .

[0032] Furthermore, the end of the insert block 23 is slidably installed inside the circular groove 22 , and the rotation of the threaded sleeve 21 can drive the insert block 23 to move in the slot 13 and the movable groove 14 through the circular groove 22 and the push block 24 .

[0033] Furthermore, the first connection block 31 and the second connection block 32 cooperate with each other, the second connection block 32 can be inserted into the second connection block 32, and the rotating bolt 33 can fix the first connection block 31 and the second connection block 32 together.

[0034] Working principle: During installation, the right bridge rod 11 and the left bridge rod 1 are connected together through the hinge 25, and then the threaded sleeve 21 is rotated to rotate the threaded sleeve 21 from the right bridge rod 11 to the outside of the left bridge rod 1. The threaded sleeve 21 is threadedly connected with the left bridge rod 1 and the right bridge rod 11, and the connection between the left bridge rod 1 and the right bridge rod 11 can be fixed on the outside. The threaded sleeve 21 moves relative to the push block 24, and the end of the push block 24 is slidably installed on the inner side of the circular groove 22, and the push block 24 slides in the circular groove 22. Therefore, when the threaded sleeve 21 moves, the push block 24 drives the insert block 23 to move in the movable groove 14, so that the insert block 23 is moved out of the movable groove 14 and inserted into the inner side of the slot 13, and the left bridge rod 1 and the right bridge rod 11 can be connected and fixed on the inside, which can further strengthen the connection strength of the left bridge rod 1 and the right bridge rod 11, and is more practical.

[0035] When storing, the threaded sleeve 21 is reset to the right bridge rod 11 to release the fixed connection between the left bridge rod 1 and the right bridge rod 11. Then, the right bridge rod 11 is moved and flipped through the hinge 25 so that the hubs 12 on the left bridge rod 1 and the right bridge rod 11 fit together. At the same time, the first connecting block 31 is inserted on the inner side of the second connecting block 32. At this time, the bolt 33 is rotated. The bolt 33 passes through the first connecting block 31 and the second connecting block 32. The left bridge rod 1 and the right bridge rod 11 can be stored and fixed through the cooperation of the limiting structure 3 and the hinge 25, thereby reducing space occupancy and facilitating storage.
