The utility model discloses a measuring and boring positioning rule for a wiring clamp. The measuring and boring positioning rule comprises fixed steel bars, fastening bolts and fastening nuts, and is characterized in that the left end and the right end of each fixed steel bar are perpendicularly connected respectively to a left positioning rail and a right positioning rail which are provide with graduated scales; two longitudinal positioning sliders at the upper and lower parts are arranged on each of the left positioning rail and the right positioning rail which are provide with graduated scales; transverse positioning rails provided with the graduated scales are fixed to positions between the longitudinal positioning sliders on the left positioning rail and the right positioning rail which are provide with graduated scales; two positioning sliders provided with sample punching holes are arranged on each of the transverse positioning rails provided with the graduated scales. According to the measuring and boring positioning rule, due to longitudinal adjustment and positioning as well as transverse adjustment and positioning, determination of all hole locations of the wiring clamp can be finished once according to hole distance values, so that the boring positioning efficiency is high, the hole distance accuracy is high, the hole locations are clearly marked, the wiring clamp manufacturing efficiency and quality as well as normal progress of works can be guaranteed, and the measuring and boring positioning rule can be widely used in engineering such as overhaul, technical innovation, intellectualized reconstruction and the like of a transformer substation.
