Abstract

The invention provides a telescopic mechanism in stationery and the stationery with the telescopic mechanism. The telescopic mechanism includes a shell, a rack II is embedded in the upper end of the shell; the lower end of the rack II is engaged with two gears; the two gears are mounted on the inner wall of the shell through rotating shafts; the two gears are uniformly engaged with the upper end of the rack I; the rack I is embedded in the top end in the shell. The rack I is fixed to the upper end of a clamping assembly, a left end of the clamping assembly is fixed with an extension spring, the extension spring is fixed on the inner left wall of the shell, and the clamping assembly is arranged in the shell. Compared with the prior art, the telescopic mechanism has the following beneficialeffects that gear transmission is utilized, extending work is achieved, elastic force is utilized for returning the clamping assembly to the original position, and protection work is achieved.

Description

technical field [0001] The invention relates to a telescopic mechanism in stationery and the stationery with the mechanism, belonging to the technical field of stationery. Background technique [0002] Stationery includes student stationery, office stationery, gift stationery, etc. Student stationery is one of the most important branches of stationery products. The main user group is students. Office stationery, as the name suggests, is office stationery. The main target group of office stationery is enterprises and careers.
