The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As depicted in figs. 1 and 2, the utility model be easy to folding in opening automatically of rod receive many folding packs and draw together: middle rod, umbrella head 2 and be installed in the deployment spring of excellent inner chamber.Wherein, described deployment spring is made up of separate upper springs 31 and lower springs 32.Be example with the triple folding umbrella in the present embodiment, described in rod slided successively from outside to inside by pipe 13 in pipe 12 and one joint in a joint outer tube 11, the joint and be socketed to form.

Special feature of the present utility model is: also comprise the brace 5 that is connected between described upper springs 31 and the lower springs 32, as Fig. 2 and shown in Figure 5, the top of these brace 5 bottom margins and described middle pipe 12 offsets, described upper springs 31 is limited in described outer tube 11 inner chambers thus, the power that provides outer tube to flick is provided in the bottom of nest on its top and the umbrella, described middle pipe 12 and interior pipe 13 inner chambers, the power that pipe 12 and interior pipe 13 flicked during its top and described brace 5 offseted to provide are provided 32 of described lower springs.Because the internal diameter of outer tube is bigger, the line of described upper springs 31 is directly done slightly than the line of lower springs 32 footpath, and the external diameter of this upper springs 31 also does greatly than the external diameter of lower springs 32, and the elastic force of this upper springs 31 is greater than the elastic force of lower springs 32 thus.
