Detailed Description

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a propaganda device is recruited in colleges and universities convenient to poster is updated, the on-line screen storage device comprises a

base

1, 1 upper end of base is fixed with

motor

2, 2 upper ends of motor are fixed with mobile jib 4 through its output shaft, 4 outlying solid fixed cylinder 3 of mobile jib are located to 2 upper ends of motor fixed with the cover, 3 lateral walls of solid fixed cylinder rotate install a plurality of threaded sleeve 7 that are the longitudinal symmetry setting, the terminal surface is fixed with bevel gear 11 in the threaded

sleeve

7, 4 peripheries of mobile jib are fixed with the awl fluted disc 5 that is the symmetry setting, awl fluted disc 5 and bevel gear 11 mesh, the 7 endotheca of threaded sleeve is equipped with threaded rod 18, two upper and lower threaded rod 18 outer ends are fixed with fixed plate 8.

Specifically, the periphery of the fixed cylinder 3 is provided with a through hole 9 matched with the threaded sleeve 7, the periphery of the through hole 9 is provided with an annular limiting groove 10, and the periphery of the threaded sleeve 7 is fixedly provided with an annular limiting block 15 matched with the annular limiting groove 10; the direction of movement of the threaded sleeve 7 is limited.
