Description of reference numerals:

1 umbrella frame cylinder, 1-1 bone bar, 1-2 circular arc projection, 2 dial sleeve, 2-1 scale, 2-2 nose cone, 3 inner sleeves, 4 adjustment screw, 5 dies, 6 center thimbles, 7 stage clips.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

Embodiment 1: like Fig. 1-shown in Figure 4, a preferred embodiment of the present invention comprises and is used to be positioned at portion of round India and China, is used to be inserted in the center thimble 6 that plays the effect of fixing circle seal on the paper.Comprise in addition with screw fit and lay respectively at outside umbrella frame cylinder mechanism 1 and be positioned at inner screw propulsion mechanism; Wherein the outline top of umbrella frame cylinder mechanism is circular; The lower end then disperses to form some fulcra bar 1-1, and the outside of fulcra bar bottom is with the die 5 of outstanding fulcra bar bottom.

Umbrella frame cylinder 1 inwall is provided with internal thread and dial sleeve 2 is spiral marking connections; The lower end of umbrella frame cylinder is provided with many fulcra bar 1-1, is similar to the umbrella frame of umbrella, and the binding site thickness of bone bar 1-1 and umbrella frame cylinder lower end because thin, so the bone bar is flexible, just can be swung by external force slightly as hinge between the 0.5-2 millimeter.The middle part of every bone bar all is provided with circular arc projection 1-2.

The lower end of dial sleeve 2 is designed to cone shape, closely contacts with the circular arc projection of umbrella frame cylinder 1; On the outer wall of dial sleeve upper end scale is arranged; All be provided with screw thread on the dial sleeve inner and outer wall, there are local internal thread and inner sleeve 3 spiral marking connections in the upper end; There are local external screw thread and umbrella frame cylinder spiral marking connection in the lower end.

All be provided with screw thread on inner sleeve 3 inner and outer walls, outer wall and dial sleeve spiral marking connection; Inwall and adjustment screw 4 spiral marking connections; Through hole and center thimbles 6 in the middle of the inner sleeve 3 are matched in clearance, allow the center thimble to move up and down, and the through holes in the middle of the inner sleeve 3 have step, and restriction center thimble unlikelyly down spills when mobile.
