Abstract

The invention relates to the technical field of stretching devices, and discloses a stretching device for physical exercise, which comprises a bottom plate and a seat plate, a first swing arm and a second swing arm are movably arranged between the bottom plate and the seat plate, the first swing arm and the second swing arm are arranged in a splayed shape, a connecting cabinet is fixedly mounted on the outer wall of the bottom plate, a control box is fixedly installed at the top of the connecting cabinet, and a first arc-shaped cabinet and a second arc-shaped cabinet are fixedly installed on the left side and the right side of the control box correspondingly. When tendon stretching is needed, an athlete sits on the seat plate, the two legs of the athlete are placed on the first swing arm and the second swing arm respectively, the athlete controls rotation of the two rotary knobs with hands to enable the first swing arm and the second swing arm to swing respectively, and therefore tendon stretching can be freely conducted, the first swing arm swings to enable the left leg to be opened, the second swing arm swings to enable the right leg to be opened, the two legs can also be stretched at the same time, the tendon stretching effect is better, use is more convenient, and the upper half body does not need to do large-amplitude actions.

Description

technical field [0001] The invention relates to the technical field of tendon stretching devices, in particular to a tendon stretching device for physical exercise. Background technique [0002] In order to prevent sudden movement from causing ligament strain, it is necessary to perform stretching exercises before sports. In the prior art, athletes usually place their legs on a higher platform when performing stretching, and the other leg Support, and then perform stretching exercises, but this method supports the body with one leg during stretching, which will not only increase the difficulty of stretching, reduce the efficiency of stretching, but also easily stand unstable and fall, resulting in injury ; There are also some athletes who press the legs by the way of the step, but the effect of the leg press is poor, and it is difficult to fully stretch the tendons; [0003] The Chinese patent announcement number is: the invention patent of CN110124271B, which provides a ki...
