Abstract

The invention discloses a screwing control clutch and a pull rope fitness training device. Comprising a first half clutch, a second half clutch, a matching fixing ring and a screwing ring arranged on the outer side of the second half clutch in a sleeving mode, a first clamping piece and a second clamping piece which correspond to each other and are detachably connected are arranged on the first half clutch and the second half clutch respectively; the screwing ring is provided with a sliding protrusion back on to the first half clutch, a matching groove corresponding to the sliding protrusion is formed in the face, facing the screwing ring, of the matching fixing ring, and the sliding protrusion is clamped into or slides out of the matching groove when the screwing ring rotates. The screwing ring is provided with a guiding part used for guiding the screwing ring to rotate. The opening and closing direction of the clutch can be perpendicular to the input direction of a power source; the clutch opening and closing process is stable and reliable, clamping is not prone to occurring, and the requirement for rigidity of parts is low; and the structure is simple, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a body-building training device for a screw-in control clutch and a drawstring. Background technique [0002] With the improvement of living standards and people's awareness of their own health, more and more people start strength training. Strength training can exercise the body, strengthen the muscles of the human body, and improve the metabolism of the human body. However, limited by the size and weight of traditional fitness equipment, it is difficult for people to perform corresponding strength training at home, and they can only go to the gym or other places for related training, which greatly restricts the feasibility of training. [0003] In order to limit the volume of fitness equipment, it may be necessary to make the direction of clutch opening and closing perpendicular to the direction of power source input, which cannot be achieved by existing clutches. ...
