Onto third gear；First gear is mounted on motor shaft, and by motor shaft in the effect engaged with the first gear ring of first gear
On movement be transmitted on the first gear ring；Second gear is mounted on motor shaft by torque clutch, and second gear and rotation
The effect for the tooth engagement opened on pivoted housing inner headed face is that the movement on motor shaft is transmitted on rotary sleeve；2 the first fixed rings
Inner headed face passes through the effect that bearing is mounted on 2 the first gear ring peripheries and is easy for installation rotary sleeve, while being also convenient for revolving
The rotary motion of pivoted housing；The effect that the circumferentially uniform N being provided in N number of first circular hole is 6 or 7 or 8 on above-mentioned support wheel end face
The second straight pin is easy for preferably to be inserted on support wheel；The diameter of first circular hole, the second circular hole and third circular hole is all the same
Effect is easy for the movement of the second straight pin；Fixed ring band has the function of that certain elasticity is easy for installation fixed block, while again just
Play the role of support in support wheel.
In use, fixed ring band is nested in the joint for needing rehabilitation first, the second straight pin at this time will
It can be inserted into the second fixed ring, support wheel and third fixed ring；Second straight pin, which will play support wheel, limits its movement
Purpose；When the supporting point position of joint recovering protection equipment needs replacing, motor machine at this time is moved, and the motor of movement will
It will drive motor shaft movement, motor shaft will will drive first gear movement；First gear will drive the first gear ring to move, and first
Gear ring will drive third gear movement under the action of 6 groups of teeth, and third gear will drive the second straight pin to move, at this time
The second straight pin internal screw thread and the second circular hole and third circular hole that will be opened on it under the action of the internal screw thread opened
It moves in the axial direction, so that the second straight pin is cancelled the restriction effect of support wheel, in the second straight pin in screw thread
Cooperate in lower motion process, the second straight pin at this time will play restriction effect to the movement of support wheel, so rotation at this time
Pivoted housing has an active force to second gear, and under the action of torque clutch, motor shaft at this time will not drive the second tooth
Wheel movement；Motor shaft will be rotated around own axes；After the teeth on the first gear ring have moved, support wheel at this time can be with
Free movement, there is no limit effects to support wheel for the second straight pin；So rotary sleeve does not have active force to second gear；Motor shaft
Will the movement of driving torque clutch, the torque clutch of movement will drive second gear to move, and second gear will drive
Rotary sleeve movement；Rotary sleeve will drive fixed trunnion to move 60 degree, and fixed trunnion will drive support wheel to move, to reach
Change the purpose of supporting point；During fixed trunnion movement, due to the effect of 6 groups of teeth on the first gear ring, so at this time
The first gear ring will not play driving effect to third gear, so third gear will be transported under the action of the return spring
Dynamic, the third gear of movement will drive the second straight pin to move, so that the second straight pin is tightly contacted with support wheel；When
When the second straight pin and the first circular hole face, the second straight pin at this time will enter in the first circular hole on support wheel, at this time
Support wheel will not surround the first straight pin rotary motion；Rotary sleeve will not also move, and joint recovering protection at this time is set
Standby supporting point replacement terminates；Support wheel will not around the first straight pin rotation purpose be in order to, prevent support wheel move to
Human body causes uncomfortable influence.

Dynamic motor 18 will will drive motor shaft 15 and move, and motor shaft 15 will will drive first gear 14 and move；First gear 14 will
The first gear ring 6 can be driven to move, the first gear ring 6 will drive third gear 20 to move under the action of 6 groups of teeth 21, third tooth
Wheel 20 will drive the second straight pin 12 to move, the internal screw thread and the second circle that the second straight pin 12 at this time will be opened on it
It is moved in the axial direction under the action of the internal screw thread opened on hole 22 and third circular hole 23, so that 12 pairs of branch of the second straight pin
The restriction effect of support wheel 13 is cancelled, in the second straight pin 12 in being threadedly engaged lower motion process, the second straight pin at this time
12 will play restriction effect to the movement of support wheel 13, so rotary sleeve 1 at this time has an active force to second gear 16,
Under the action of torque clutch 17, motor shaft 15 at this time will not drive second gear 16 to move；Motor shaft 15 will enclose
It is rotated around own axes；After the teeth 21 on the first gear ring 6 have moved, support wheel 13 at this time can with free movement, second
There is no limit effects to support wheel 13 for straight pin 12；So rotary sleeve 1 does not have active force to second gear 16；Motor shaft 15 will
Driving torque clutch 17 moves, and the torque clutch 17 of movement will drive second gear 16 to move, and second gear 16 will
Rotary sleeve 1 is driven to move；Rotary sleeve 1 will drive fixed trunnion 10 to move 60 degree, and fixed trunnion 10 will drive support wheel 13
Movement, to achieve the purpose that change supporting point；During fixed trunnion 10 moves, due to 6 groups of teeth on the first gear ring 6
21 effect, so the first gear ring 6 at this time will not play driving effect to third gear 20, so third gear 20 will
It is moved under the action of return spring 7, the third gear 20 of movement will drive the second straight pin 12 to move, so that second
Straight pin 12 is tightly contacted with support wheel 13；When the second straight pin 12 and the first 24 face of circular hole, the second straight pin at this time
12 will enter in the first circular hole 24 on support wheel 13, and support wheel 13 at this time will not be around the first straight pin 11 rotation fortune
It is dynamic；Rotary sleeve 1 will not also move, and the supporting point replacement of joint recovering protection equipment at this time terminates；Support wheel 13 will not enclose
Purpose around the rotation of the first straight pin 11 is to prevent the movement of support wheel 13 from causing uncomfortable influence to human body.
