1. A putting practice device for training of keeping a putter face square and controlling putting strength, the putting practice device comprising:
a base plate having an advance groove formed such that a lateral side of a central part of the base plate is recessed, wherein the advance groove is configured to enable a golf ball to be mounted therein and to advance forwards therealong;
a distance display part formed on the base plate and configured to measure a distance of a backstroke along a central line of the advance groove;
a pair of striking parts mounted on the base plate such that the advance groove is interposed therebetween, wherein the pair of striking parts has a space therebetween narrower than a width of a head of a putter so that the head of the putter strikes the pair of striking parts during putting, and each of the pair of striking parts has a striking surface configured to be struck by the head of the putter and formed on the same line with each other;
an impact sensor installed on the striking surface of each of the pair of striking parts and configured to detect impact of the head of the putter striking each of the pair of striking parts; and
a display part configured to display a time point at which the impact by the head of the putter is detected, and a degree of strength applied to the impact sensor by the head of the putter.
