The first tube 11 is arranged on the side of the first rotating shaft 12 and connected with the first rotating shaft 12, the second tube 21 is arranged on the side of the second rotating shaft 22 and connected with the second rotating shaft 22, and when the first rotating shaft 12 or the second rotating shaft 12 rotates, the relative angle between the first tube 11 and the second tube 21 changes. The first cover plate 13 covers an end of the first rotating shaft 12 away from the second rotating shaft 22, and the second cover plate 23 covers an end of the second rotating shaft 22 away from the first rotating shaft 12. First pivot 12 or second pivot 12 rotates certain angle and can fix, exerts extra thrust and can promote first pivot 12 or second pivot 12 continues to rotate, rotates certain angle after fixed once more, until first pipe 11 with the contact of second pipe 21 realizes multi-angle rotation fixed.

As shown in fig. 2, a central shaft hole 121 is formed in the first rotating shaft 12, the central shaft hole 121 is a through hole, a protruding central shaft 221 is formed in the second rotating shaft 22, and the central shaft 221 is rotatably inserted into the central shaft hole 121, that is, the first rotating shaft 12 and the second rotating shaft 22 are rotatably connected through the central shaft hole 121 and the central shaft 221. The end of the part of the middle shaft 221 inserted into the middle hole 121 of the rotating shaft is a middle shaft tooth portion 2211, the cylindrical diameter of the middle shaft tooth portion 2211 is smaller than that of the middle shaft 221, and the middle shaft tooth portion 2211 is inserted into the middle hole 121 of the rotating shaft. The middle shaft tooth portion 2211 includes a plurality of uniformly distributed teeth. A first spacer 222 is disposed around the middle shaft tooth portion 2211, the first spacer 222 is located at a junction between the middle shaft tooth portion 2211 and the middle shaft 221, and when the middle shaft tooth portion 2211 is inserted into the rotating shaft central hole 121, the first spacer 222 blocks between the middle shaft 221 and the first rotating shaft 12, so as to facilitate relative rotation between the first rotating shaft 11 and the second rotating shaft 22.

The end of the first rotating shaft 12 away from the second rotating shaft 22 has a top block groove 122, and the end of the top block groove 122 is communicated with the rotating shaft central hole 121. As can be seen from fig. 3, a top block 123 and a spring 124 are disposed inside the top block groove 122, the top block 123 and the spring 124 together form a limiting assembly, the top block 123 is disposed at one end of the top block groove 122, which is communicated with the rotating shaft central hole 121, the spring 124 is disposed between the top block 123 and a side wall of the top block groove 122, which is far away from one end of the rotating shaft central hole 121, and the spring 124 supports and limits the top block 123. The middle shaft tooth portion 2211 is aligned with the top block groove 122, the top block 123 is clamped between the teeth of the middle shaft tooth portion 2211, the top block 123 limits and fixes the middle shaft tooth portion 2211, when the second rotating shaft 22 is subjected to an additional steering force, the middle shaft tooth portion 2211 rotates around the axis of the middle shaft tooth portion 2211, if the first rotating shaft 12 is simultaneously subjected to a steering force opposite to that of the second rotating shaft 22, the middle shaft tooth portion 2211 rotates relative to the top block 123, the top block 123 is clamped between other adjacent teeth of the middle shaft tooth portion 2211, at this time, the force application is stopped, and the top block 123 again limits the middle shaft tooth portion 2211. Preferably, the central shaft tooth portion 2211 has 6 teeth, that is, the top block 123 limits the central shaft tooth portion 2211 to 60 ° every time it rotates. Thus, since the first tube 11 and the second tube 21 form a block with each other, the relative angle of the first tube 11 and the second tube 21 varies from 60 ° to 300 °, and the angle is fixed every time the relative angle of the first tube 11 and the second tube 21 varies by 60 °. It should be noted that the middle shaft tooth portion 2211 may be provided with different numbers of teeth, so as to change the limit angle variation range of the first tube 11 and the second tube 21, and achieve limit fixation with different angle variations.

The U-shaped pad 125 is disposed between the gear hole pad 126 and the first shaft 12, and the U-shaped pad 125 is coupled to the first shaft 12. The screw 128 is fixedly connected to the middle shaft tooth portion 2211, and the second washer 127 is disposed between the screw 128 and the gear hole washer 126, so as to facilitate the relative rotation between the first rotating shaft 11 and the second rotating shaft 22. The first washer 222, the U-shaped washer 222 and the second washer 127 play a role of buffering, and simultaneously, due to the friction force among the first washer 222, the U-shaped washer 222 and the second washer 127 and other components, the relative rotation between the first rotating shaft 12 and the second rotating shaft 22 is alleviated.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
