[0015] The present invention provides an auxiliary component, and when the user still needs to exercise the upper limb joints, the user can exercise the upper limb joints under the drive of the auxiliary component, close the foot exercise component, start the auxiliary component, and the auxiliary cylinder of the auxiliary component will push the auxiliary push rod to lift the push plate, and the push plate is used to make the anti-slide plate bear force evenly, and then the anti-slide plate drives the sliding column to move upward, and the sliding column drives the user's hand to move upward, so as to exercise the upper limb joints, the sliding column moves upward, and the tilting rod moves upward with the upper end of the sliding column, and the lower end of the sliding column moves upward. Driven by the sliding column, the sliding column moves toward the top of the arc groove. When the lower end of the sliding column moves, the stop column of the clamping piece will abut against the groove between the multiple protrusions to prevent the clamping piece from being separated from the thigh fixing section when the stop column pushes the thigh fixing section. After the stop column abuts against the groove between the multiple protrusions, the sliding column continues to rise, and the stop column pushes the thigh fixing section to flip upward, thereby completing the exercise of the upper limb joints and the lower limb joints. The set force of the second push rod or the auxiliary component cannot make the sliding rod slide to the top of the arc groove. The first push rod can be slidably inserted in the first cylinder when the power is not supplied; the second push rod can be slidably inserted in the second cylinder when the power is not supplied.

[0016] By setting up the oil storage airbag, after long-term use, the friction at the hinge of the thigh fixed section and the calf fixed section becomes larger, which is not conducive to the operation of the equipment. The user's feet can cooperate with the first pushing member or the user's hands can cooperate with the auxiliary member to raise the sliding rod to the top of the arc groove. At the top of the arc groove, the oil guide pipe will abut against the arc baffle, and the oil guide pipe is stuck in the oil outlet. The spring pull rope and the extrusion rod follow the movement of the thigh fixed section to squeeze the oil storage airbag. The oil storage airbag flows out the lubricating oil through the oil outlet and the oil outlet. An articulation space is formed between the articulation of the thigh fixed section and the calf fixed section, so that the lubricating oil flows to the articulation of the thigh fixed section and the calf fixed section, reducing the friction at the articulation of the thigh fixed section and the calf fixed section, thereby extending the use time of the equipment.

[0017] By setting the airbag, when the excess lubricating oil flows to the bottom of the arc-shaped baffle in the articulated space and is finally stored in the U-shaped temporary storage part, when the foot exercise component moves, the airbag will hit the airbag baffle, so that the airflow in the airbag flows out through the oil storage steel pipe, and then the airflow in the airbag can lubricate the articulated space again with the lubricating oil stored in the temporary storage part. When the temporary storage part does not store lubricating oil, the airflow in the airbag can disperse the dust in the articulated space to prevent the dust from clogging the outside of the articulated space. The present invention has a simple structure, can exercise the upper limb bone joints and lower limb bone joints well, and can always keep the connection at the joints of the equipment smooth, reduce friction, and thus extend the service life of the equipment.

When at the top of the arc groove 526, the oil guide pipe 64 will abut against the arc baffle 61, and the oil guide pipe 64 will be stuck in the oil outlet 544, and the spring 6 The pulling rope 5 causes the extrusion rod 66 to follow the thigh fixing section 411 to move and squeeze the oil storage airbag 546. The oil storage airbag 546 flows out the lubricating oil through the oil outlet groove and the oil outlet 544. A hinge space is formed between the hinge of the thigh fixing section 411 and the calf fixing section 412, so that the lubricating oil flows to the hinge of the thigh fixing section 411 and the calf fixing section 412, thereby reducing the friction of the hinge of the thigh fixing section 411 and the calf fixing section 412, thereby extending the use time of the device.

[0049] By setting the airbag 63, when the excess lubricating oil flows to the bottom of the arc-shaped baffle 61 in the articulated space and is finally stored in the U-shaped temporary storage portion 640, when the foot exercise component 40 moves, the airbag 63 will hit the airbag baffle 542, so that the airflow in the airbag 63 flows out through the oil storage steel pipe 62, and then the airflow in the airbag 63 can lubricate the articulated space again with the lubricating oil stored in the temporary storage portion 640. When the temporary storage portion 640 does not store lubricating oil, the airflow in the airbag 63 can disperse the dust in the articulated space to prevent the dust from clogging the outside of the articulated space. The present invention has a simple structure, can exercise the upper limb bone joints and lower limb bone joints well, and can always keep the connection at the joints of the equipment smooth, reduce friction, and thus extend the service life of the equipment.
