The invention relates to the technical field of photovoltaic panel frames, in particular to a photovoltaic panel frame convenient for photovoltaic panel installation, which comprises a bottom frame and a clamping mechanism installed on the bottom frame, a supporting mechanism is in threaded connection with an adjusting mechanism, two adjusting belts respectively penetrate through two through grooves, bolts are in threaded connection with a shell, and the shell is provided with a plurality of through holes. The bolt is rotationally connected with the clamping block, the bottom of the clamping block is of a zigzag structure, and the adjusting belt is clamped between the shell and the clamping block; a restraining mechanism is installed between the supporting rod and the supporting plate, after the limiting mechanism and the supporting mechanism are installed, an adjusting belt can be pulled to enable the adjusting belt and a fixing belt to be in a straightened state, the connecting effect between the supporting mechanism and the supporting plate is improved, the supporting plate can be rotated and inclined by adjusting the length of the adjusting belt in the overhauling process, and the overhauling efficiency is improved. The adjusting belt and the fixing belt can extend to pull the supporting plate, hand holding is not needed, maintenance is convenient, the adjusting belt is clamped and fixed through the clamping block by rotating the bolt, and looseness is avoided.
