It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 5, the present embodiment provides a reversing structure including a first base 1, a second base 2, and a connecting column 3; the first base 1 is formed with a positioning port 101; the second base 2 is provided with a positioning protrusion 201 which is matched with the positioning opening 101; a connecting column 3 connects the first base 1 and the second base 2;

one end of the connecting column 3 is in running fit with the first base 1, so that the connecting column 3 is linked to rotate the second base 2, the other end of the connecting column 3 is hinged to the second base 2, so that the second base 2 has a first adjusting state and a second adjusting state, in the first adjusting state, the second base 2 and the first base 1 are alternately arranged, in the second adjusting state, the second base 2 rotates around a hinge point of the second base 2, so that the second base 2 and the first base 1 are mutually perpendicular, the positioning protrusion 201 is clamped in the positioning opening 101, and the connecting column 3 is limited to rotate.

In this embodiment, as shown in fig. 1 to 4, a first base 1, a connecting column 3 and a second base 2 are sequentially connected from top to bottom, one end of the connecting column 3 is rotatably arranged on the first base 1, and the other end is hinged with the second base 2; thus, the second base 2 is provided with two reversing processes, the first reversing process: the connecting column 3 is linked with the second base 2 to rotate 360 degrees on the horizontal plane under the action of external force (namely, the connecting column rotates from the angular position of the second base 2 in fig. 1 and 2 to the angular position of fig. 3); the second reversing process: under the action of external force, the second base 2 is driven to rotate around the hinging point of the second base 2 and the connecting column 3, so that the second base 2 has a first adjusting state and a second adjusting state, in the first adjusting state, the first base 1 and the second base 2 are arranged alternately (namely, are arranged in parallel along the up-down direction), at the moment, the first base 1 and the second base 2 are connected by the connecting column 3, and the connecting column 3 drives the second base 2 to rotate according to the operation process; in contrast, in the second adjustment state, the second base 2 is driven to rotate under the action of external force until the second base 2 rotates to be perpendicular to the first base 1 (as shown in fig. 4), and the positioning protrusion 201 is clamped in the positioning opening 101, so that the second base 2 is fixed at the first base 1, and then the rotation of the connecting column 3 can be limited; under the cooperation of the positioning protrusion 201 and the positioning opening 101, the first base 1 and the second base 2 can be kept in a vertical state, so that the verticality of the newspaper second base 2 is convenient; in summary, in the process of switching the second base 2 from the first adjustment state to the second adjustment state, the second base 2 can be switched from the horizontal state to the vertical state, so as to flexibly change the position thereof.

The rotation axis of one end of the connecting column 3 rotating relative to the first base 1 is perpendicular to the rotation axis of the second base 2 rotating relative to the other end of the connecting column 3.

In this embodiment, the rotation axis of one end of the connecting post 3 rotating relative to the first base 1 is set along the Y axis, the rotation axis of the second base 2 rotating relative to the other end of the connecting post 3 is set along the Z axis, the two rotation axes are perpendicular to each other, so that the second base 2 can rotate along with the connecting post 3 in the first adjusting state, and the second base 2 can rotate to be perpendicular to the first base 1 in the second adjusting state, without being interfered by the connecting post 3, and the rotation direction is more flexible.

The positioning opening 101 is of an open structure.

In this embodiment, as shown in fig. 2, the bottom of the positioning opening 101 is in an open structure, so that the positioning protrusion 201 quickly extends into the positioning opening 101 in the rotation process of the second base 2, thereby avoiding shielding; of course, when the second base 2 is rotated reversely, the positioning protrusion 201 can be made to extend out of the positioning opening 101 rapidly, so that the limit fit of the two can be released rapidly.

The second base 2 is provided with a first avoiding opening 202 for avoiding the connecting column 3 when the first adjusting state and the second adjusting state are switched.

In this embodiment, as shown in fig. 5, in the process of switching the second base 2 from the first adjustment state to the second adjustment state, in order to avoid the end of the connection post 3 abutting against the second base 2, a first avoiding opening 202 is provided on the second base 2, and the first avoiding opening 202 is used for avoiding the connection post 3 so as to facilitate forward rotation or reverse rotation of the second base 2; further, an avoidance port two 203 is arranged on the second base 2, and the avoidance port two 203 is used for avoiding the first base 1, so that the situation that the positioning protrusion 201 cannot extend into the positioning port 101 due to the fact that the second base 2 is abutted against the first base 1 in the rotation process is avoided. Of course, as shown in fig. 5, in order to make the positioning protrusion 201 quickly extend into the positioning opening 101, the positioning protrusion 201 is disposed on a side surface protruding from the second base 2, and the second avoidance opening 203 is disposed above the positioning protrusion 201.

The first base 1 is screwed with a threaded rod 4, the positioning protrusion 201 is provided with a threaded hole 204 matched with the threaded rod 4, and in the second adjusting state, the threaded rod 4 is screwed into the positioning protrusion 201 through the threaded hole 204.

The second base 2 is provided with a handle 5.

In this embodiment, as shown in fig. 5, in order to facilitate manual rotation of the second base 2, a handle 5 is provided on the second base 2.
