The invention relates to solar water heater mounting equipment, in particular to drilling equipment for mounting a wall-mounted solar water heater. According to the technical aim to be achieved, the drilling equipment for mounting the wall-mounted solar water heater is small in danger and can precisely control the drilling position. In order to achieve the technical aim, the drilling equipment formounting the wall-mounted solar water heater comprises a mounting plate, universal wheels, a supporting plate, first bearing pedestals, a first rotary rod, a first crank, a sliding block, a sliding rail, a fixed plate, a second bearing pedestal and the like. The universal wheels are arranged on the front side, the rear side, the left side and the right side of the mounting plate, the left portionof the upper side of the mounting plate is connected with the supporting plate, and the first bearing pedestals are mounted on the left side and the right side of the upper side of the supporting plate in a bolt connection manner. The drilling equipment achieves the effects of being small in danger and capable of precisely controlling the drilling position, the drilling equipment is placed indoors, a drill bit stretches out to drill the outer side of a wall, and therefore the danger of drilling can be reduced.
