[0030] The wrapped feedback component 3 includes a wrapped connection shell 8 and a feedback control panel 9.

The inner wall of the wrapped outer ring 39 is fixedly connected to the outer wall of the drive motor 35. The feedback control panel 9 is fixedly arranged on the outer wall of the wrapped connection shell 8.

[0031] The built-in electrode 24 slides in the sensing area of ​​the wrapped sensing ring 18, and the sensing electrode ring 30 slides in the sensing area of ​​the sliding sensing ring 15. The wrapped sensing ring 18 and the sensing electrode ring 30 are both connected to the feedback control panel 9 by signal, and the drive motor 35 is connected to the feedback control panel 9 by signal.

[0032] During specific use, the device of the present invention is connected to a power supply, the sliding induction ring 15, the wrapped induction ring 18 and the feedback control panel 9 are turned on, the built-in electrode 24 and the induction electrode ring 30 are turned on, the driving motor 35 is turned on, and the sliding induction ring 15, the wrapped induction ring 18, the driving motor 35, the built-in electrode 24, and the induction electrode ring 30 are all connected to the feedback control panel 9 signal.

[0033] The device is controlled to operate in the squeezing mode through the feedback control panel 9. The user holds the grip squeezing member 5. When the user starts to apply force, the arc-shaped squeezing rod shaft 19 is squeezed, and the middle position of the arc-shaped squeezing rod shaft 19 approaches the supporting main shaft member 4. The fixed insertion rod 20 moves inward and is inserted into the insertion ring 17 of the insertion sensing member 11. The drag spring 22 is dragged and stretched, and the built-in electrode 24 in the end sliding piece 21 slides into the sensing range of the wrapped sensing ring 18. At this time, the time axis is fed back on the feedback control panel 9. Due to the arc-shaped characteristics of the arc-shaped squeezing rod shaft 19 itself, the connecting member 25 connected to the arc-shaped squeezing rod shaft 19 moves along The extended expenditure member 13 slides in the up and down directions, and the induction electrode ring 30 moves along the sliding induction ring 15 of the extended expenditure member 13. The connecting ring 28 squeezes the push spring 27 during the upward movement.

The detection is ended, the detection result is locked, and the operator lets go of his hand. Under the resetting action of the push spring 27 and the drag spring 22, the gripping force extrusion support device 1 and the bidirectional pushing member 6 reset themselves.

[0034] When the operator has greater strength, the arc-shaped extrusion rod shaft 19 can be squeezed until the induction electrode ring 30 slides to the top of the sliding induction ring 15, and the feedback control panel 9 is adjusted to the confrontation mode, the driving motor 35 starts to run, the driving ring 36 rotates to drive the rotating ring 37 to rotate, and the spiral protrusion 38 is engaged with the spiral groove 33 of the pushing tube 31. As the rotating ring 37 rotates, the pushing tube 31 is pushed to move toward the middle support member 12. At this time, the pushing ring 32 squeezes the pushing spring 27 to pressurize the connecting ring 28, and the pressure is fed back to the arc-shaped extrusion rod shaft 19. The operator resists the pressure until the operator gives in, the connecting ring 28 moves down, and the induction electrode ring 30 slides to the bottom of the sliding induction ring 15. The operator releases the arc-shaped extrusion rod shaft 19, the built-in electrode 24 is reset, and the timing stops.

[0035] In the confrontation mode, the operation time of the driving extrusion member 7 is converted into a certain grip force value for feedback according to the actual situation, so as to improve the authenticity and accuracy of the device detection.

[0036] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.
