The unlocking slider 31 is provided with a pin hole 312 above the deformation portion 311. The pin 8 that fixes the middle rod 1 and the upper nest 2 passes through the pin hole 312 and fixes the unlocking slider 31 to the middle rod 1 and the upper nest 2. The lower nest 4 and the upper nest 2 are connected by the buckling structure 32; when the unlocking switch 6 moves downward, the pull wire 7 pulls the deformation portion 311 to deform downward along the axial direction of the middle rod 1 and triggers the buckling structures 32 to separate from each other to achieve unlocking.

[0032] Furthermore, the buckle structure 32 connecting the lower nest 4 and the upper nest 2 is specifically as follows: Figure 1 As shown, the extension portion 22 extends downward to form a symmetrically arranged first ear portion 23, the inner wall of the first ear portion 23 is provided with a second convex buckle portion 231, the second convex buckle portion 231 is provided with a second guide inclined surface 2311 inclined downward, and the bottom of the deformation portion 311 of the unlocking slider 31 is in conflict with the second guide inclined surface 2311; the outer wall of the extension portion 22 opposite to the first ear portion 23 is provided with a first convex buckle portion 221, the first convex buckle portion 221 is provided with a first guide inclined surface 2211 inclined upward; the extension portion 42 of the lower nest 4 extends upward to form a second ear portion 43, and the second ear 43 is provided with a The buckling hole 431 is designed to be interlocked with the first convex buckle portion 221. When locked, the second ear portion 43 slides upward along the first guide inclined surface 2211 of the first convex buckle portion 221 until the buckling hole 431 is buckled and fixed with the first convex buckle portion 221; the middle rod 1 is provided with an avoidance hole 12. After the middle rod 1 is inserted into the upper nest 2, the second convex buckle portion 231 passes through the avoidance hole 12 and protrudes into the middle rod 1, and the first ear portion 23 and the second ear portion 43 overlap with each other. The buckling hole 431, the first convex buckle portion 221, and the second convex buckle portion 231 form the buckling structure 32.

[0033] The working principle of the opening and closing structure of this embodiment is as follows: Figure 2As shown, when the umbrella is opened, the lower nest 4 moves upward, and when the second ear portion 43 reaches the position of the upper nest 2, the second ear portion 43 is blocked by the first convex buckle portion 221, and the second ear portion 43 is deformed outward along the first guide inclined surface 2211. When the buckle hole 431 coincides with the position of the first convex buckle portion 221, the buckle hole 431 and the first convex buckle portion 221 are buckled and fixed to each other, the lower nest 4 is relatively fixed to the upper nest 2, and the umbrella is fully opened; Figure 3 As shown, when the umbrella is folded, the button 62 exposed on the handle 5 is pushed downward along the elongated through hole 52, and the switch slider 61 fixedly connected thereto moves downward synchronously, driving the pull wire 7 to move downward. The pull wire 7 stretches the deformation portion 311 downward to deform, and the bottom of the deformation portion 311 slides obliquely along the second guide and forces the second convex buckle portion 231 to expand outward, and the overlapping first ear portion 23 and second ear portion 43 are deformed outward accordingly, and the buckling hole 431 on the second ear portion 43 and the first convex buckle portion 221 are separated from each other, and the lower nest 4 moves downward to complete the unlocking; after releasing the button 62, the deformation portion 311 affected by the unlocking slider 31 rebounds, and drives the pull wire 7 and the unlocking switch 6 to move upward and return to their original positions.
