Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, in particular to a leg clamp. Background Art

[0002] As people's living standards improve, the national fitness enthusiasm continues to rise, and various types of fitness equipment are constantly being updated. Local fitness equipment for the buttocks, legs, pelvic floor muscles, etc. is also in great demand in the market. The pelvic floor muscles refer to the muscle group that closes the pelvic floor. This muscle group is like a "hanging net". The urethra, bladder, vagina, uterus, rectum and other organs are tightly suspended by this "net" to maintain their normal position in order to perform their functions. Once the elasticity of this "net" deteriorates and the "hanging force" is insufficient, it will cause the organs in the "net" to be unable to maintain their normal position, resulting in corresponding functional disorders, such as pelvic organ prolapse, incontinence, hemorrhoids, etc., especially in postpartum women and older women, the phenomenon of pelvic floor muscle relaxation is more obvious.

[0003] The leg clamps currently on the market include a left-swing structure, a right-swing structure, a left leg support board and a right leg support board, and a rotating shaft is provided between the left-swing structure and the right-swing structure; the left-swing structure and the right-swing structure are opened by a torsion spring, and can be retracted against each other after being squeezed. When the leg clamp is in use, the adjacent end faces of the left-swing structure and the right-swing structure generate friction due to squeezing, resulting in inflexible and not smooth rotation, which can easily affect the training effect. Moreover, the rotation is only achieved by the opening and closing of the torsion spring, which increases the pressure of the torsion spring, which is prone to deformation during long-term use, resulting in damage to the leg clamp.
