Abstract

The invention relates to an umbrella, in particular to an unfolding and folding fixing device for an umbrella. The unfolding and folding fixing device comprises a middle rod, an upper umbrella nest fixed at the upper end part of the middle part, a lower umbrella nest sliding along the middle part, an upper clamping sleeve, a lower clamping sleeve and a movable clamping sleeve. An elastic clamping hook is arranged on the upper clamping sleeve; a raised outer edge is arranged on the lower clamping sleeve; and a clamping hole and an elastic multi-jaw clamping joint are arranged on the movable clamping sleeve. Compared with the prior art, the unfolding and the folding of the umbrella are easily positioned by the movable clamping sleeve, the upper clamping sleeve and the lower clamping sleeve or the movable clamping sleeve and an upper clamping unit; a spring bow is not required to be pressed with figures when the unfolding and folding fixed device is in use, thus a user can not feel painful and can use the umbrella safely and reliably; an upper spring bow, a lower spring bow and a nail retaining hole are not required to be arranged on the middle rod, so that the stress strength of the middle rod is added, the cost of raw materials is reduced, the processing flow is shortened, the process is simpler and the energy cost, the processing cost and the assembly cost are reduced.

Description

technical field [0001] The invention relates to an umbrella, in particular to a retractable and fixed device for an umbrella. Background technique [0002] Umbrella stands in the prior art usually include a metal middle rod, a metal upper slingshot, a lower slingshot and a retaining nail installed on the middle rod body, an upper nest device installed on the top of the middle rod, and a A lower nest device that slides on the rod, and an umbrella rib group stretched on the upper nest device and the lower nest device. [0003] This kind of umbrella stand has the following disadvantages: the upper slingshot, the lower slingshot and the retaining nails must be processed in the metal middle rod to install the upper slingshot, the lower slingshot and the retaining nails, thereby destroying the stress strength of the metal middle rod; The cost is high; in the process of production and assembly, it takes a lot of manpower and energy; the use of general umbrella stands must press th...
