The invention relates to the technical field of sports equipment, in particular to a multifunctional basketball shooting machine. The multifunctional basketball shooting machine comprises a machine frame, a basket and a left-right moving mechanism, wherein the basket is fixedly arranged on the machine frame; the left-right moving mechanism comprises a moving trolley, a seat, a first crank, a worm,a worm wheel, a second crank and a connecting rod. The first crank is installed on the moving trolley, and the rotation axis of the first crank is in the left-right direction. The worm and the worm wheel are both installed on the moving trolley, the axis of the worm is in the left-right direction, the axis of the worm wheel is in the front-back direction, the worm meshes with the worm wheel, andthe worm is connected with the first crank through a transmission mechanism. One end of the second crank is fixedly connected with the worm wheel, the other end of the second crank is in pivot joint with the connecting rod, and the connecting rod is in pivot joint with the machine frame. According to the multifunctional basketball shooting machine, a player pedals the first crank as power to drivethe moving trolley, so that the player moves left and right relative to the basket when shooting, interest is increased, and the lower limb strength, the anticipation ability, the balance ability andthe drifting basketball shooting ability of the player are trained.
