A twin hammer impact tool includes a hammer spindle, an inner ring hammer sleeved on the hammer spindle, an outer ring hammer disposed around the inner ring hammer, and rolling beads. The inner ring hammer has bead grooves each having a ball half-shape, and angularly spaced-apart hammer projections. The inner ring hammer is reciprocally movable relative to the hammer spindle while rotating together with the hammer spindle. The outer ring hammer has guiding grooves. The bead grooves respectively face and open toward the guiding grooves. Each rolling bead is received within one of the bead grooves and one of the guiding grooves. An output hammer has angularly spaced engagement projections to engage the hammer projections.

A grease output device for an electrical grease gun has a body, a double-cam member and a driving member. The body has a holder and a seat mounted with the holder. The double-cam member connects to the body and has a driven unit and a driving unit. The driven unit has a driven gear and two cams misaligning with the driven gear. The driving gear has two rings mounted around the cams and two pistol rods connecting to the rings. The driving unit has a driving gear engaging with the driven gear. The driving member connects to the body to rotate the driving gear so the driven gear is rotated to push the rings. Hence, the grease can flow out of the body successively by the pistol two pistol rods moving back and forth alternatively.
