The rotating shaft 7 is rotatably assembled at the bottom of the support 2, one end of which is fixed with a ratchet 8, and the other end is fixed with a spring spring 9, and the outer end of the spring spring 9 is connected to the inner wall of the support 2. The limit block 10 is movably arranged in the support 2, and its upper end extends into the shaft hole of the support 2 and is opposite to the position of the buckle head 6 when it is retracted, and its lower end is arranged opposite to the ratchet teeth of the ratchet 8. The limit block 10 is arranged in a movable manner in the support 2, and the upper end of the limit block 10 extends into the shaft hole of the support 2 and is opposite to the position of the buckle head 6 when it is retracted. An elastic member 12 is connected between the inner wall of the support 2 and the stop block 10 to reset and abut against the ratchet teeth of the ratchet wheel 8; one end of the pull rope 11 is fixed on the rotating shaft 7, and the other end is fixedly connected to the upper nest; an adjustment device is provided at the side end of the umbrella handle 1, and a rotating member 15 is provided on the adjusting device, and the rotating member 15 extends through and connects with the rotating shaft 7.

[0049] When the user opens the umbrella, he presses the button by hand, the hook piece moves backward and disengages from the outer tube, and the middle rod 4 stretches under the tension of the umbrella opening spring; driven by the pull rope 11, the lower nest moves upward, the umbrella rib assembly 3 opens, and the umbrella is opened; at this time, the buckle head 6 is engaged with the control tube in the support 2 under the action of the reset spring, and the front end of the buckle head 6 supports the limit block 10 and presses down, so that the bottom end of the limit block 10 is separated from the ratchet teeth of the ratchet wheel 8, and because the pull rope 11 moves upward after the umbrella is opened, the clockwork spring 9 is in a tightened state at this time; when closing the umbrella; press the button by hand, the reset teeth will When the umbrella is folded, the pull cord 11 will be retracted along with the middle rod 4 and will be wound around the rotating shaft 7 under the action of the clockwork spring 9. Therefore, even if the user accidentally releases the pull cord 11 when folding the umbrella, the pull cord 11 will be restrained by the pull cord 11 and there will be no rebound problem.

[0050] In this embodiment, the adjusting device includes a connecting rod 13, a connecting tube 14 and a rotating member 15. The side wall of the umbrella handle 1 is provided with a through hole connected to the support 2. The connecting tube 14 is detachably connected to the side wall of the umbrella handle 1 and connected to the through hole. The connecting rod 13 passes through the connecting tube 14 and is connected to the rotating shaft 7. The rotating member 15 is rotatably arranged at the outer end of the connecting tube 14, and the rotating member 15 can move horizontally along the surface of the connecting tube 14 and be fixed with the connecting tube 14. The rotating member 15 is connected to the connecting rod 13.

[0051] At present, when the automatic umbrellas on the market are folded, although the ribs can be automatically folded by one-touch operation, the retraction of the umbrella pole still needs to be completed with the help of both hands. If the umbrella is used outdoors when it rains, when the user enters the room, he will inevitably hold the umbrella cloth and press it manually to fold it, and his arms will inevitably get wet by the rain on the umbrella cloth. In addition, it is inconvenient for the user to stretch his arms to press when folding the umbrella in a narrow space such as a car. At this time, the user can hold the umbrella handle 1 with one hand and twist the rotating member 15 with the other hand to rotate it. At this time, the connecting rod 13 can drive the rotating shaft 7 therein to rotate, so as to reel in the drawstring 11. When the drawstring 11 is retracted, the middle rod 4 can be retracted by pulling the upper nest to fold it, so that the umbrella folding action can be completed by rotating the rotating member 15, and the user does not need to hold the wet umbrella cloth.

[0052] In this embodiment, an annular groove 16 is provided on the outer circumferential surface of the connecting cylinder 14, and a plurality of connecting members 17 adapted to the outer circumferential surface of the connecting cylinder 14 are annularly connected to one end of the rotating member 15 close to the connecting cylinder 14, and a clamping block adapted to the annular groove 16 is provided on the inner side of the other end of the connecting member 17. The rotating member 15 can move horizontally along the outer surface of the connecting cylinder 14, and a clamping tooth 18 is provided on one end of the connecting cylinder 14 close to the rotating member 15, and a clamping groove 19 adapted to the clamping tooth 18 is provided on one end of the rotating member 15 close to the connecting cylinder 14. The rotating member 15 moves horizontally so that the clamping tooth 18 is engaged with the clamping groove 19, thereby limiting and fixing the rotating member 15, and the rotating member 15 is slidably engaged with the connecting rod 13.

[0053] Because the middle rod 4 of a traditional automatic umbrella is affected by the umbrella opening spring, its length is fixed and cannot be adjusted according to different usage scenarios and user needs. For example, when used in a narrow space, a longer middle rod 4 may cause inconvenience, and in situations where a larger shielding area is required, a middle rod 4 of a fixed length may not meet the needs; but when the device is opening the umbrella, since the front end of the buckle head 6 is still in a state of pressing the limit block 10, the bottom end of the limit block 10 is separated from the ratchet teeth of the ratchet wheel 8, so the shaft 7 can rotate freely forward and reverse at this time. Therefore, when the user needs to adjust the length of the middle rod 4, he only needs to rotate the rotating member 15 forward and reverse, thereby driving the shaft 7 to rotate through the connecting rod 13, and then the middle rod 4 can be opened. The drawstring 11 is wound up or unwound, and the middle rod 4 is retracted by winding up the drawstring 11, and the middle rod 4 is released by unwinding the drawstring 11, so as to adjust the folded length of the middle rod 4. Finally, after adjusting the appropriate length, the rotating member 15 can be pressed inwardly to engage the engaging teeth 18 and the engaging grooves 19.
