Abstract

The invention relates to the technical field of fitness equipment, in particular to a crotch stretching double-leg tendon turning machine, and aims to solve the problems that an existing crotch turning machine is single in function in the prior art. The crotch stretching double-leg tendon turning machine comprises a seat, a hand wheel is arranged above the seat, a seat bottom plate is arranged at the bottom of the seat, and a gear transmission set is arranged in a cavity between the seat and the seat bottom plate. The gear transmission set comprises two gears meshed with each other, center shafts of the gears are connected with leg supports, each leg support comprises a rotating main arm, a swing support and an adjusting structure, and the swing support is connected with the rotating main arm through the adjusting structure and connected with a foot swing device through the rotating structure. A foot swinging device comprises a foot fixing belt, a motor and a worm and gear transmission group structure, an electric control device electrically connected with the motor is arranged below the seat bottom plate, pulleys are arranged below the leg support, the hip turning exercise can be performed, ankle rotating and tendon stretching can also be performed, and the fitness equipment has good development prospects in the technical field of fitness equipment.

Description

technical field [0001] The invention relates to the technical field of body-building equipment, in particular to a crotch stretching double-leg twisting machine. Background technique [0002] There is an old saying: One inch of tendons can prolong life by ten years; especially those who study art and dance need to open their hips. This part is quite painful, and improper operation will cause muscle strain. During the practice process, it is also necessary to do it step by step , the existing crotch stretching machines on the market have the following problems: the function is single, and the auxiliary effect on the user is small; a single machine corresponds to the purpose of one-way exercise, and the practicability is not strong. If the user needs multiple exercises , you need to purchase a variety of machines, resulting in a large space occupation and resource-intensive concubine; poor operational flexibility and applicability, different users have differences in the width...
