Below in conjunction with accompanying drawing the utility model is described further.

Clip 10 is screwed on bicycle handlebar, and sleeve 9 usefulness screws and clip 10 are fixing, and mobile jib 3, secondary bar 7 usefulness hollow circular-tubes are made, and mobile jib 3 is made matched in clearance with secondary bar 7, and secondary bar 7 can be slided in mobile jib 3.Drive 1 cannelure on the secondary bar 7 lower end cylindricals, also can drive a plurality of cannelures.A screw is opened in mobile jib 3 lower ends, and mobile jib 3 upper ends and cross bar 1 one ends are hinged, and cross bar 1 other end and cross break bar 11 are hinged, and the hinged place can be passed through to fix in advance

Shape otic placode and pin are realized; Hinged between two bias bars 4, and a little dome is made in the end of a bar therein, makes a little recessed circle at another root boom end, after two bars are hinged, next spacing with the cooperation of these two convex-concave circles.Hinged between two cross break bars 11, and spacing in aforementioned identical mode.Two other end points one end and cross bar 1 middle part of two bias bars 4 are hinged, and an end and mobile jib 3 middle parts are hinged.Tarpaulin 2 is used cotton, and linings such as nylon mircofabric are made, and is fixed on the umbrella stand, can also do fringe 5 around the tarpaulin 2, so both can keep the sun off and rainwater, again sight line that can the overslaugh cyclist.

During use, secondary bar 7 lower ends draw mobile jib 3 to proper height to tighten locknut 6 by pin female 8 and cover letter 9 fixing (tightening after can selecting proper height that locknut 8 is inserted cannelure), open bias bar 4, cross bar 1, cross break bar 11 then respectively, folded umbrella is opened, can the sun-shading rain-proof effect.By adjusting the deflection angle of clip 10 and sleeve 9, folded umbrella is tilted as required to front, rear, left and right.

Time spent not, bias bar 4, cross bar 1, cross break bar 11 are folding to mobile jib 3, unclamp locknut 6, make secondary bar 7 slip into mobile jib 3 inner chambers, unclamp locknut 8, take off folded umbrella, and this moment, folded umbrella was similar to common umbrella.

Handle 12 structures are made a call to two holes, and are opened a stria thereon as shown in Figure 3 on metal or other material, during walking, folded umbrella can be taken off, and two secondary bars 7 are inserted respectively in two holes of handle 12, use screw-driving, promptly can be used as common umbrella and use.
