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. The enlarged end portion has a part identical to the inner upper rod for being engaged with the porous piece. The enlarged end portion has a part having an inner diameter identical to that of the outer lower rod for being passing through the outer lower rod. The middle rod sleeve has a sliding groove at the lateral surface thereof for being inserted by a sliding block and a spring. The sliding block is connected to a driving piece. The driving piece passes through the inner upper rod to be connected to the pull piece of the handle.
