An extension rod 9 is provided at the bottom of the engaging gear 3. A pulling mechanism 10 for pulling the extension rod 9 is provided at the bottom of the lower rod barrel 6, the pulling mechanism 10 is rotatably arranged, and the pulling mechanism 10 can be fixed to the lower rod barrel 6 after being pulled down and rotated, and the engaging gear 3 can be automatically reset. The upper rotating member 1 and the lower rotating member 2 are pivotally connected to each other through a pivot 11 , which passes through the upper rotating member 1 , the meshing gear 3 and the lower rotating member 2 , and the lower part of the pivot 11 is located in the extension rod 9 .

[0021] Reference Figures 1 to 4The pulling mechanism 10 includes a rotating member 12 and a sliding member 13. The sliding member 13 is located on the top surface of the rotating member 12. Both the rotating member 12 and the sliding member 13 can slide up and down. The rotating member 12 is rotatably arranged. After the rotating member 12 is rotated, it can be fixed to the lower rod barrel 6. The extension rod 9 is connected to the sliding member 13. Two upper cutouts 14 are provided at the bottom of the lower rod barrel 6. A first groove 15 is provided in the middle of the top surface of each upper cutout 14. The two upper cutouts 14 form two upper extensions 16 at the bottom of the lower rod barrel 6. A second groove 17 is provided in the middle of the bottom surface of each upper extension 16. The top of the rotating member 12 is provided with two lower cutouts 18, and the two lower cutouts 18 form two lower extensions 19 on the top of the rotating member 12. The middle of the top surface of the lower extension 19 is provided with a convex portion 20 adapted to the first groove 15 and the second groove 17, and the upper extension 16 is adapted to the lower cutout 18, and the lower extension 19 is adapted to the upper cutout 14. The lower rod tube 6 is connected to the top of a lower rod 21, and the rotating member 12 and the sliding member 13 are sleeved on the outer periphery of the lower rod 21. The extension rod 9 is located in the lower rod 21, and the extension rod 9 is connected to the sliding member 13 by a rivet (not shown in the figure). The outer periphery of the lower rod 21 is provided with two symmetrical strip grooves 22, and the rivet (not shown in the figure) passes through the sliding member 13, the extension rod 9 and the two strip grooves 22. In this embodiment, the extension rod 9 includes two extension rod plates 91 that are symmetrical. The rotating member 12 can rotate around the lower rod 21, and the rotating member 12 and the sliding member 13 can slide up and down along the lower rod 21. The two strip grooves 22 provide a movable space for the rivet (not shown in the figure) when the rotating member 12 and the sliding member 13 slide up and down, and the rivet (not shown in the figure) can slide up and down in the two strip grooves 22.

[0022] Reference Figure 1 and Figure 3 The bottom of the lower engagement groove 8 is provided with a spring 23, and the spring 23 contacts the bottom surface of the engagement gear 3. The spring 23 is used for the engagement gear 3 to automatically reset upward, and the engagement gear 3 automatically resets upward while driving the rotating member 12 and the sliding member 13 to slide upward. The top surface of the upper rotating member 1 is provided with a cover 24, and the cover 24 is used to cover the top of the upper rotating member 1, making the folding rotating assembly more beautiful as a whole.

[0023] Reference Figures 1 to 4The design principle of the utility model is as follows: in the use state or folded state, the meshing gear 3 is meshed with the upper meshing groove 7 and the lower meshing groove 8 at the same time, the lower extension 19 is located in the upper cutout 14, the convex part 20 is located in the first groove 15, and the upper extension 16 is located in the lower cutout 18. At this time, the upper rotating member 1 and the lower rotating member 2 are relatively fixed. When the upper rotating member 1 and the lower rotating member 2 are to be folded or unfolded, the rotating member 12 is pulled downward, and the sliding member 13 slides downward with the rotating member 12. At this time, the sliding member 13 pulls the extension rod 9 and the meshing gear 3 to move downward, so that the meshing gear 3 is separated from the upper meshing groove 7, and then the rotating member 12 is rotated clockwise so that the convex part 20 is located in the second groove 17. At this time, the rotating member 12 is fixed with the lower rod tube 6, and the meshing gear 3 and the extension rod 9 after being pulled down are fixed. At this time, the upper rotating member 1 and the lower rotating member 2 can be rotated, so as to be folded or unfolded. When the rotating member 12 is rotated counterclockwise, when the lower extension portion 19 is facing the upper incision 14 and the upper extension portion 16 is facing the lower incision 18, the rotating member 12 is released. At this time, under the action of the spring 23, the lower extension portion 19 is re-located in the upper incision 14, and the protrusion 20 is re-located in the first groove 15, and the upper extension portion 16 is re-located in the lower incision 18, and the engaging gear 3 is re-engaged with the upper engaging groove 7 and the lower engaging groove 8 at the same time. At this time, the upper rotating member 1 and the lower rotating member 2 are relatively fixed, and both cannot rotate.

[0024] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
