Experimental design bobble flinger

The utility model discloses an experimental design bobble flinger, this flinger are held in the palm by end rail, pull rod, calibrated scale, ball and the fixation clamp block group becomes, all design flutedly in the one end of end rail and pull rod, end rail passes through the fixed pin piece with the pull rod and links to each other in the one end of recess, and the calibrated scale is fixed in the recess of end rail and pull rod through same fixed pin piece, the ball holds in the palm and fixes in the unnotched one end of pull rod, end rail, pull rod, calibrated scale, ball hold in the palm forms the flinger body, and it is fixed on the desktop through fixed clamp splice. Draw angle and originated angular dimension can simulate multiple experimental design techniques such as multiple -factor, multilevel DOE after hanging position, transform through the difference of chooseing different kinds of bobbles for use, choose for use different radical rubber bands to reach and set for the rubber band.
