Abstract

The invention relates to a waist twisting device having a protecting function. The device comprises a hand rack, wherein a waist twisting mechanism is arranged on the periphery of the hand rack; the waist twisting mechanism comprises a vertical drum which is vertically buried in the ground; a horizontal bearing is arranged in the vertical drum; a round rod is inserted on an inner ring of the bearing; a rotary disc is arranged at the free end of the round rod; a round ring, which is coaxial with the rotary disc, is arranged on the periphery of the rotary disc; a plurality of opening limiting grooves are formed in the upper end face of the round ring at intervals; the widths of the various opening limiting grooves are sequentially increased; a compression spring is additionally arranged on the side face of the vertical drum; one end of the compression spring abuts against a convex shoulder at the lower side of the vertical drum and the other end abuts against the round ring; a horizontallimiting pillar, which protrudes outwards, is arranged on the outer circumference of the rotary disc; and the horizontal limiting pillar is arranged in any one of the opening limiting grooves. Basedupon cooperation between the horizontal limiting pillar and the opening limiting grooves, motions of the horizontal limiting pillar can be limited by the opening limiting grooves, so that a rotating angle of the rotary disc is subsequently limited; and by forming the opening limiting grooves which are different in width in the round ring at intervals, the rotating angle of the rotary disc is regulated and controlled.
