Description

The liftable lectern

Technical field

The utility model belongs to desk, the liftable lectern that particularly a kind of teaching, lecture, report are used.

Background technology

At present, the electric up-down that use in market and the lectern of two kinds of energy liftings of mechanical elevating, the weak point that they exist is complex structure, cost height, big, the consumed power of noise, therefore, promotes difficulty; Particularly in school, still use the common lectern that can not regulate height, this lectern can't adapt to different height personnel's use, and lectern is low excessively, and the user of service need bend over, the forward-looking sight line of too high influence, and the time has been grown, and the people is felt under the weather.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provide a kind of can lifting, simple in structure, noiselessness, easy to operate liftable lectern,
