Golf practicing device having velocity detection function

Abstract

A golf practicing device includes a housing, a sensor mounted in the housing and provided with a velocity sensing member and a position sensing member, and a rotation disk rotatably mounted in the housing and having a periphery formed with a protruding velocity sensed portion that is movable to pass through the sensor to connect the velocity sensing member of the sensor, and a protruding position sensed portion that is movable to pass through the sensor to connect the position sensing member of the sensor. Thus, the golf practicing device has a velocity detection function.
