Abstract
A multi-step positioning device of a trunk pull rod has a pair of pull rods at two sides thereof. Each pull rod has an inner upper rod and an outer lower rod therein. The rod body has two sides of round arc shapes. After engaging, the round arc portions of the two rods are formed with gaps. Porous pieces are placed in the gaps. The porous piece passes through the outer lower rod. The upper end of the outer lower rod is connected to an upper rod sleeve. Protruding buckles at two sides of the upper rod sleeve buckles with the buckling holes with respect to the outer lower rod. The lower end of the inner upper rod is connected to a lower rod sleeve. The slender end of the lower rod sleeve passes through the inner upper rod. Part of the enlarged end portion thereof having an outer diameter identical to that of the inner upper rod passes through the outer lower rod. The top end surface of the lower rod sleeve serves to be inserted by the sliding piece. A driving piece is connected at the upper end of the sliding piece. The driving piece passes through the inner upper rod to be connected to the control piece of the handle. The enlarged end of the lower rod sleeve is formed with at least one through hole facing to the porous piece. Each through hole is passed by a buckling ball. Each sliding piece is installed with semicircular grooves facing to the through hole.
