It refers to a kind of mechanical auxiliary device used for bending plant muscle, which includes a transplantable mechanical structure, a joint system of shoelaces and a line and elastic element characterized by mechanical drive. The mechanical drive has three elements: coupling, base and hollow drum The butt joint and the base constitute a type of backward switch, while the drum butt joint is a kind of angular backward rotation device,There's also a rope purchased from a hollow drum that goes around the side of the element. The rope passes through the pulley on the main tool bar of the mechanical structure and has an elastic element which is connected to a main bracket. This configuration allows bending back movement to allow mechanical energy to be stored in elastic elements once the foot plant touches the surface, which can then be used to enhance the movement of the curved plant. Finally, with the correct parameters,This mechanism reduces the muscle energy requirement for the fleischion muscles, thereby reducing fatigue for activities that require this exercise.Se refiere a un dispositivo mecanico asistencial para musculos de flexion plantar que comprende una estructura mecanica portable, sistemas de sujecion para el calzado del pie y un accionamiento mecanico con una cuerda y un elemento elastico caracterizado porque el accionamiento mecanico posee 3 elementos: acoplador, base y tambor hueco siendo que el acoplador y la base conforman un mecanismo tipo interruptor retractil； y el acoplador con el tambor, un mecanismo angular retractil, y una cuerda que se adquiere al tambor hueco y se enrolla en la superficie lateral de dicho elemento. Dicha cuerda pasa a traves de una polea ubicada en la barra principal de la estructura mecanica hasta sujeta un elemento elastico que a su vez esta unido a un soporte principal. Esta configuracion permite que una vez que la planta del pie este en contacto con una superficie, el movimiento de flexion dorsal permita almacenar energ
