Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

The utility model provides a bicycle flower-drum as shown in fig. 1-3 easy equipment, including

dabber

1, 1 outside cover of dabber is equipped with casing 2, and both ends all are equipped with bearing 3 with 1 junction of dabber about casing 2, one side that casing 2 was kept away from to bearing 3 is equipped with nut 4,

nut

4 and 1 threaded connection of dabber, the fixed clamp plate 5 that is equipped with in the 4 outside of nut, 3 outer lane tops of bearing and bottom are all pegged graft and have cylindricality locating lever 6, two positioning groove 7 have been seted up with a side surface that bearing 3 contacted in both ends about casing 2, the one end that clamp plate 5 was kept away from to cylindricality locating lever 6 extends to inside positioning groove 7.
