The number of the umbrella surface rod 21 is six, and the number of the brace rod 22 is also six. In other embodiments, the number of the umbrella surface rod 21 and the brace rod 22 can be other numbers.

[0037] The collapsible umbrella has an open state and a folded state. When in the open state, the umbrella frame is open relative to the umbrella handle, and when in the folded state, the umbrella frame is folded relative to the umbrella handle. When the crank structure rotates relative to the umbrella handle about the axis, the collapsible umbrella is switched between the open state and the folded state.

[0038] One end of the linkage rope 3 is fixedly connected with the sliding seat 23, and the other end of the linkage rope 3 is fixedly connected with the handle structure.

[0039] The handle structure comprises a rotating shaft 4, a handle 5, a first component, a second component, a connecting piece 6, a limiting piece 10 and an auxiliary structure.

[0040] The rotating shaft 4 extends along the left-right direction and can rotate relative to the umbrella handle about an axis of rotation extending along the left-right direction. The rotating shaft 4 has a first end 41 in the left-right direction. In an embodiment, the first end 41 is a left end. The left end is arranged in the inner rod 12 of the umbrella handle, and the first end 41 does not protrude from the outer seat 11 of the umbrella handle. In order to increase the contact area between the rotating shaft 4 and the inner rod 12 of the umbrella handle and prevent the rotating shaft 4 from coming out of the inner rod 12 of the umbrella handle during rotation, the inner rod 12 of the umbrella handle can further comprise a bearing support 121. The thickness of the bearing support 121 in the left-right direction is greater than the thickness of other parts of the inner rod 12 of the umbrella handle in the left-right direction, so that the bearing support 121 is more deeply inserted and fitted with the first end 41. The linkage rope 3 is fixedly connected with the rotating shaft 4, and during rotation of the rotating shaft 4 about the axis of rotation, the linkage rope 3 can further be wound on or reduced from the rotating shaft 4.

[0041] The rocking handle 5 is movable relative to the rotating shaft 4 in the left-right direction. Specifically, in an embodiment, the rocking handle 5 comprises a rocking handle base 51 and a rocking handle body 52 fixedly connected to the rocking handle base 51, the rocking handle body 52 extending in the up-down direction for a user to hold and rock, the rocking handle base 51 being connected to the rotating shaft 4 through a connecting member 6 to prevent the rocking handle 5 from being detached from the rotating shaft 4.

In an embodiment, the rocking handle 5 further comprises a rocking handle cover 53, which is arranged on the screw nut 61 to prevent the screw nut 61 from being exposed. The rotating shaft 4 and the rocking handle base 51 are provided with engagement structures. In an embodiment, the engagement structures are a section of external thread 42 arranged at the right side of the rotating shaft 4 and an internal thread (not shown in the figure) arranged in the rocking handle base 51 and matched with the section of external thread 42. When the rocking handle base 51 rotates clockwise around the axis, the internal thread gradually matches with the external thread 42 until the rocking handle base 51 and the rotating shaft 4 are engaged through the internal thread and the external thread 42, and the rocking handle base 51 drives the rotating shaft 4 to rotate clockwise around the axis synchronously. When the rocking handle base 51 rotates counterclockwise around the axis, the internal thread gradually disengages from the external thread 42 until the rocking handle base 51 is completely disengaged from the rotating shaft 4, and the right side of the rocking handle base 51 abuts against the screw nut 61, and the rocking handle base 51 drives the rotating shaft 4 to rotate counterclockwise around the axis synchronously. In this embodiment, the rotating shaft 4 and the rocking handle base 51 rotate counterclockwise synchronously through the friction between the rocking handle base 51 and the screw nut 61. In other embodiments, two sets of engagement structures can be arranged between the rotating shaft 4 and the rocking handle base 51, i.e., a first external thread (not shown in the figure) arranged at the left side of the rotating shaft 4 and a second external thread (not shown in the figure) arranged at the right side of the rotating shaft 4, and a smooth non-threaded surface (not shown in the figure) being arranged between the two sections of external thread. When the rocking handle base 51 rotates counterclockwise around the axis, the rocking handle base 51 gradually disengages from the first external thread arranged at the left side and gradually matches with the second external thread arranged at the right side until the rocking handle base 51 drives the rotating shaft 5 to rotate counterclockwise around the axis synchronously.

[0042] The first component is fixedly arranged relative to the umbrella handle, the second component is sleeved on the rotating shaft 4, one of the first component and the second component is a pawl seat, the other of the first component and the second component is a ratchet seat 8, the pawl seat comprises a pawl seat body 71 and a pawl 72, the pawl 72 is rotationally connected relative to the pawl seat body 71 about a pawl axis of extension in the left-right direction, and an elastic member 73 is arranged between the pawl seat body 71 and the pawl 72 to always abut the pawl 72 against the ratchet seat 8, so that the pawl 72 is in contact and cooperation with the ratchet seat 8, in an embodiment, the first component is the ratchet seat 8, the ratchet seat 8 is fixedly connected with the inner rod 12 of the umbrella handle through cooperation of a screw 81 and a nut 82, and the second component is the pawl seat, the rotating shaft 4 passes through the ratchet seat 8 and the pawl seat.
