Abstract
A device for punching holes in a bicycle rim includes a flange extending radially from a base, the flange having a plurality of rails disposed thereon each for a puncher slidably disposed thereon. Each of the punchers has a first block and a second block respectively extending upwardly from two ends thereof and a cylinder disposed longitudinally to each of the first blocks having a shaft retractably extending therefrom which extends through the first block and has a pin member disposed on a free end thereof. Each of the second blocks has a longitudinal hole defined therethrough so that when a bicycle rim is disposed between the first blocks and the second blocks each of the pin members punches a hole through the rim.
