[0041] In the description of the embodiment, the terms "upper", "lower", "right", etc. orientation or position relationship is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0042] As shown in Figure 1 and Figure 2 The utility model provides a connecting rod structure 10, the connecting rod structure 10 can be used as push rod for user to hold and use. As shown in Figures 3 to 8As shown, the connecting rod structure 10 comprises a first rod 100, a second rod 200 and a sliding sleeve 300. One end of the first rod 100 and one end of the second rod 200 are rotationally connected, and the rotation point is A. The sliding sleeve 300 is sleeved on the outside of the first rod 100 and the second rod 200, and the sliding sleeve 300 can move to a first position and a second position. The sliding sleeve 300 in the first position can hide the rotation point A, so that the first rod 100 and the second rod 200 are limited in the coaxially connected unfolded state, that is, the sliding sleeve 300 in the first position is just sleeved on the outside of the rotation connection of the first rod 100 and the second rod 200, so that the first rod 100 and the second rod 200 cannot be freely rotated. The sliding sleeve 300 in the second position can be located outside the first rod 100 or the second rod 200 and can expose the rotation point A, so that the first rod 100 and the second rod 200 can be rotated around the rotation point A to the folded state.

[0043] Compared with the push rod that cannot be folded and stored in the prior art, the connecting rod structure 10 provided by the utility model is rotationally connected around the rotation point A by the first rod 100 and the second rod 200, so that the connecting rod structure 10 has a folding property and can be folded and stored, which is beneficial to improve the storage degree.

[0044] Further, when the first rod 100 and the second rod 200 are in the folded state, the sliding sleeve 300 can be reversely moved to a third position limited and abutted with the second rod 200. After the first rod 100 and the second rod 200 are rotationally folded, the sliding sleeve 300 is reversely moved to realize the limited abutment with the rod wall of the second rod 200, which improves the stability of the folded connecting rod structure 10, so that the folded connecting rod structure 10 is not easy to be accidentally scattered.

[0045] In order to realize the rotation connection of the first rod 100 and the second rod 200, in some embodiments, the end of the first rod 100 forms a first connecting end, the first connecting end is provided with a first rotation shaft hole, the end of the second rod 200 forms a second connecting end, the second connecting end is provided with a second rotation shaft hole, and the connecting rod structure 10 further comprises a rotation shaft, which is arranged in the first rotation shaft hole and the second rotation shaft hole.

[0046] In order to improve the compactness of the rotating connection between the first rod 100 and the second rod 200, the diameters of the first rod 100 and the second rod 200 are the same, the thickness of the first connecting end is half of the first rod 100, the mounting space for the second connecting end is formed on one side of the first connecting end, and the thickness of the second connecting end is half of the second rod 200, and the mounting space for the first connecting end is formed on one side of the second connecting end. Thus, after the first connecting end and the second connecting end are connected by the rotating shaft, the thickness of the rotating connection part does not increase, thereby improving the compactness and the appearance of the push rod. Alternatively, the first connecting end and the second connecting end are both semicylindrical.

[0047] In some parallel embodiments, the end of the second rod 200 is provided with a rotating shaft seat 210, the rotating shaft seat 210 includes two rotating shaft plates 212 arranged at intervals, and a plug-in slot 211 is formed between the two rotating shaft plates 212. The end of the first rod 100 is formed with a plug-in block 110, the plug-in block 110 is inserted into the plug-in slot 211, and the rotating shaft seat 210 and the plug-in block 110 are both provided with a rotating shaft hole for the rotating shaft. Thus, the stability of the rotating connection between the first rod 100 and the second rod 200 is higher.

[0048] Of course, in other embodiments, the rotating shaft seat 210 can be arranged on the first rod 100, and the plug-in block 110 is arranged on the second rod 200. It should be noted that the plug-in slot 211 can be directly formed on the first rod 100 or the second rod 200 by slotting, so that the structures on both sides of the plug-in slot 211 form the rotating shaft plates 212, and finally form the rotating shaft seat 210; or the modular rotating shaft seat 210 can be integrated at the end of the first rod 100 or the second rod 200. Similarly, the plug-in block 110 can be formed on the first rod 100 or the second rod 200 by cutting; or the modular plug-in block 110 can be integrated at the end of the first rod 100 or the second rod 200.

The first rod 100 and the second rod 200 are arranged at an angle when in the folded state. As shown in Figure 7 and Figure 8 The first rod 100 and the second rod 200 are arranged perpendicularly when in the folded state, that is, the target angle between the first rod 100 and the second rod 200 is 90° when in the folded state. Thus, the folding and storage of the first rod 100 and the second rod 200 are more convenient. Of course, in other embodiments, the target angle between the first rod 100 and the second rod 200 when in the folded state is not limited to 90°, and can be adjusted to other angles according to requirements.
