The specific implementation mode is as follows:

in order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. Example 1

As shown in figure 1, the multifunctional ankle rehabilitation and foot therapy all-in-one machine can complete the training actions of stretching the back, bending the toes and turning the feet inwards and outwards.

As shown in figure 2, the multifunctional ankle joint rehabilitation pedicure device comprises a movable cover plate 1, an upper shell 2, a lower shell 3, a motor 4, a support rod 5, a transmission gear 6, a third movable connecting rod 7, a drain pipe 8, a foot mounting plate 9 and the like. The movable cover plate 1 is connected with the upper shell 2 by a movable hinge. The movable cover plate can be opened around the movable hinge, and feet can be put in the movable cover plate conveniently. The upper shell 2 and the lower shell 3 are fixed through screw connection. The upper shell 2 includes a support rod 5, a third movable link 7 and a foot mounting plate 9. And a sealing ring is arranged between the upper shell 2 and the lower shell 3. The upper shell 2 can be put into hot water, and the feet of the user can be soaked in the constant-temperature hot water to realize the foot massage effect. The lower case 3 contains therein the motor 4 and the transmission gear 6. The drain pipe 8 is connected to the upper housing 2, passes through the outlet of the lower housing 3, and extends to the outside of the apparatus. As shown in fig. 3, the multifunctional ankle joint rehabilitation foot treatment device extends and bends the toe, and comprises a foot mounting plate 9, a first movable connecting rod 10, a second movable connecting rod 11, a third movable connecting rod 7, a cam roller 13, an end cam 12 and the like. The foot mounting plate 9 is connected with the first movable connecting rod 10 by a rotating pair. The first movable connecting rod 10 and the second movable connecting rod 11 are connected by a rotating pair. One end of the second movable connecting rod 11 is connected with the bottom plate of the upper shell 2 through a rotating pair. The third movable connecting rod 7 is connected with the second movable connecting rod 11 through a sliding pair and a rotating pair. The slider moves along the second movable link 11. The slide block rotates around the axis of the rotation pair of the third movable connecting rod 7. The third movable connecting rod 7 can only move up and down along the bottom plate fixing hole of the upper shell 2. The magnitude of the up-and-down motion is determined by the surface shape of the face cam 12. An end face cam-link mechanism is adopted, the third movable connecting rod 7 is driven to move up and down through the rotation of an end face cam 12, the first movable connecting rod 10 and the second movable connecting rod 11 are pushed to swing, and finally the foot mounting plate 9 is driven to complete the foot dorsiflexion and toe extension movement.
