Problems solved by technology

[0002] In order to increase the flexibility of the joints, it is necessary to stretch the legs. At present, when the legs are stretched, it is usually manually pressed and stretched on the legs of the exerciser, especially when performing dance exercises. , to train this, first perform the downward split stretching training during stretching. When the strength of the stretching needs to be strengthened after the downward splitting and parallel stretching is completed, the lower stretching training needs to be performed at an angle exceeding the horizontal stretching , while the current stretching device can only perform single horizontal stretching, and cannot effectively protect the people exercising during the stretching process

Abstract

The invention relates to a leg stretching device for physical fitness, which comprises a base and a spacer arranged in the middle of a groove in the base, a left angle adjusting seat and a right angle adjusting seat are arranged in a left cavity and a right cavity respectively, and a left driving lead screw and a right driving lead screw are arranged at the bottom of the left cavity and the bottom of the right cavity respectively. A supporting rod is hinged to the left angle adjusting seat and the right angle adjusting seat, and the driving body is movably connected with the middle of the supporting rod through a connecting rod; rotating lead screws are movably connected in the left angle adjusting seat and the right angle adjusting seat respectively, and are in threaded connection with foot stands arranged in the left angle adjusting seat / the right angle adjusting seat; the rotating lead screws are connected with the first driving assembly, and the left driving lead screw and the right driving lead screw are connected with the second driving lead screw. According to the invention, horizontal tendon stretching can be stably carried out, angle tendon stretching can be carried out after horizontal tendon stretching (splitting) is completed, the exercise strength is improved, the tendon stretching speed can be effectively controlled during exercise, and an exerciser can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of physical fitness, in particular to a leg stretching device for physical fitness. Background technique [0002] In order to increase the flexibility of the joints, it is necessary to stretch the legs.
