[0031] A pressure sensor 211 is fixedly connected to one side of the shift block 209 close to the moving block 202 ; the pressure sensor 211 is of prior art and can activate a buzzer when subjected to pressure.
[0032] A connecting cavity 212 is provided inside the shift block 209, and a square shaft 213 is slidably connected to the inside of the connecting cavity 212.

[0035] Working principle: Before using this auxiliary training device for bone and joint recovery, you need to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, first place the limbs on both sides of the joint on the pad 301, and then use the Velcro 303 to tie the limbs with the strap 302;
[0036] By pulling the locking gear 210 together with the square shaft 213 outward by holding the handle 215, the locking gear 210 is dislocated and disengaged from the limiting rack 208, thereby allowing the stop block 209 to slide in the movable groove 201, and finally the stop block 209 blocks the position of the moving block 202, thereby allowing the minimum angle of the first bracket 101 and the second bracket 102 to be adjusted, and the first bracket 101 and the second bracket 102 are made close to horizontal through the movable groove 201 and the moving block 202;
[0037] When the first bracket 101 and the second bracket 102 rotate, the second rotating rod 204 and the first rotating rod 203 can maintain a certain angle under the push of the reaction spring 207, thereby allowing the moving block 202 to slide in the movable groove 201. Until the moving block 202 is blocked by the stop block 209, the angle of the first rotating rod 203 and the second rotating rod 204 changes, and under the continuous force applied by the limbs, the sleeve 205 and the movable column 206 can slide and the reaction spring 207 can be squeezed, thereby appropriately increasing the reaction force on the joint and increasing the exercise intensity;
[0038] When there is no need to increase the exercise intensity of the joints and only the flexibility of the joints needs to be exercised, and thus the joints do not need to be stressed, it is only necessary to insert the gear threaded pin 216 into the threaded hole, so that the sleeve 205 and the movable column 206 cannot continue to slide, and finally when the pressure sensor 211 contacts the moving block 202, the angle between the first bracket 101 and the second bracket 102 cannot be reduced any further, thereby avoiding excessive amplitude during exercise.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
