The invention discloses a support for transmitting a photovoltaic module. The support comprises a bottom disc, wherein four support mechanisms are vertically arranged on the bottom disc and are arranged in a rectangular shape, lower ends of the support mechanisms are connected with press mechanisms, the press mechanisms are fixed on the bottom disc via positioning pins, bearing mechanisms are arranged between a front support mechanism and a rear support mechanism and are uniformly arranged along a vertical directions, and the bearing mechanisms are fixed on the support mechanisms via claw bolts. The photovoltaic module is fixed by the bearing mechanisms, the support is very simple to use; according to sizes of different photovoltaic modules, the heights of the bearing mechanisms are adjusted, the relative distance among the bearing mechanisms is adjusted, so that the photovoltaic module is very convenient to place and take and then is clamped and fixed by a clamping mechanism; and moreover, buffering in advance is formed during the moving process, the photovoltaic module is effectively prevented from being collided and affected, so that a traditional manual transportation mode is abandoned, a potential risk during transportation is eliminated, mass moving and transportation can be achieved, time and labor are saved, and the working efficiency is improved.
