[0006] As an improvement to the present invention, the locking head is a marble, a blind hole is provided on the rear side of the marble, and the outer end of the reset spring extends into the blind hole, so that the marble maintains outward tension.

[0007] As an improvement to the present invention, the locking head is a bow-shaped card, the outer end of the return spring abuts against the bow-shaped card, and the bow-shaped card is pivotally connected to the upper inner plug through a pivot, so that the bow-shaped card maintains outward tension.

[0008] As an improvement to the present invention, an axial groove is provided on the outer wall of the topmost umbrella middle rod away from the locking head, and a convex strip for being sleeved in the axial groove is provided on the inner wall of the cylindrical umbrella opening and closing control mechanism body relative to the axial groove.

[0009] As an improvement to the present invention, a stopper protruding outward is provided at the lower end of the axial groove, and a limiting step is provided at the lower end of the convex strip to prevent the cylindrical umbrella opening and closing control mechanism body from falling off.

[0010] The utility model adopts a structure in which a convex ring is provided on the inner wall of the upper end of the cylindrical opening and closing umbrella control mechanism body, and a concave portion is provided at the lower part of the convex ring. The convex ring is configured so that when the cylindrical opening and closing umbrella control mechanism body is pushed up and the convex ring passes over the locking head, the locking head extends into the concave portion under the action of the return spring to lock the topmost umbrella middle rod with the adjacent umbrella middle rod; when the cylindrical opening and closing umbrella control mechanism body is pulled down and the convex ring presses against the locking head, the locking head retracts toward the upper inner plug direction under the action of the convex ring to unlock the topmost umbrella middle rod with the adjacent umbrella middle rod. In this way, the locking or unlocking function can be achieved by only performing push and pull. Therefore, the utility model has the advantages of simple structure and convenient use.
