Since the base 1 is provided with a plurality of clamping blocks 4, and both sides of the clamping block 4 are respectively provided with clamping shafts 5, the clamping shafts 5 can be used to connect the corresponding main umbrella ribs, and the adjacent clamping shafts 5 of two adjacent clamping blocks 4 are correspondingly arranged. Therefore, when the rotating member 3 on the annular fastener 2 is rotated downward, the rotating member 3 can be rotated into the clamping gap between the adjacent clamping shafts 5 of the adjacent clamping blocks 4, thereby realizing the installation of the main umbrella rib 6.

[0036] In actual use, when preparing the upper umbrella top, the annular fastener 2 can be first arranged on the base 1, and then the main umbrella ribs can be arranged on the clamping shafts 5 on both sides of the clamping block 4.

The assembly is convenient, avoiding the complex operation of manual punching and threading in the prior art, greatly improving the production efficiency, reducing the production difficulty and improving the aesthetics.

[0037] Furthermore, as Figure 3 shown, in the upper umbrella top structure of the utility model, a through hole 11 is arranged in the base 1 designed in this embodiment, and a fitting groove 12 is arranged on the inner wall of the through hole 11. One end of the annular fastener 2 is provided with a fitting portion 21; wherein, the fitting portion 21 is embedded into the fitting groove 12.

[0038] In this embodiment, the mutual cooperation between the fitting portion 21 and the fitting groove 12 is set to realize the quick installation and disassembly of the annular fastener 2 and the base 1, thereby simplifying the subsequent installation process. In addition, it should be noted that through the through hole 11, the upper umbrella top structure of the utility model can be clamped on the umbrella rod 7.

[0041] Further, in the upper umbrella top structure of the present utility model, a plurality of clamping shafts 5 corresponding to the plurality of clamping blocks 4 are uniformly arranged along the same horizontal circumferential direction. It should be noted that the clamping shaft 5 is an arc-shaped cylinder. In practical applications, a clamping shaft 5 can be correspondingly arranged on each clamping block 4, and the clamping shaft 5 penetrates through the clamping block 4 and extends to both sides of the clamping block 4.

[0042] Further, in the upper umbrella top structure of the present utility model, an extension portion 14 is provided on the base 1 along its circumference, and one end of the clamping block 4 is connected to the extension portion 14.

[0044] Further, in the upper umbrella top structure of the present utility model, a hook 32 is provided on the claw 31, and a clamping groove 16 adapted to the hook 32 is provided at the bottom of the extension portion 14.

[0045] As can be seen from the above description, by providing a buckle on the extension portion 14 and a claw 31 adapted to the bayonet 15 at one end of the rotating member 3 away from the annular fastener 2, when the rotating member 3 is rotated into the clamping gap, the claw 31 can be clamped into the bayonet 15, and the hook 32 can be clamped into the clamping groove 16, so as to realize clamping one end of the rotating member 3 on the extension portion 14 of the base, and further realize the fixation between the rotating member 3 and the base 1.

[0046] Further, in the upper umbrella top structure of the present utility model, the extension portion 14 is further provided with a plurality of hollow portions 17, and the plurality of hollow portions 17 are uniformly arranged on the extension portion 14 along the same circumferential direction.
