Photovoltaic module junction box positioning device

The utility model relates to the technical field of photovoltaic modules, in particular to a photovoltaic module junction box positioning device, which comprises a positioning block, a mounting block, a limiting block and a handle. A containing cavity is formed in one end of the positioning block, one end of the mounting block is arranged in the containing cavity and is in sliding connection with the containing cavity, the other end of the mounting block is arranged outside the positioning block, and displacement adjustment of the mounting block is achieved between the mounting block and the positioning block through a gear and rack mechanism; one end, far away from the positioning block, of the mounting block is movably connected with the limiting block; the side, away from the mounting block, of the limiting block is matched with the junction box. The handle is mounted in the middle of the upper surface of the positioning block. The photovoltaic junction box is simple in structure and convenient to operate,
