One of the proximity sensors 163 (e.g., the left or innermost sensor in fig. 6) is near the initial position of the guide axle 165 sliding in the limit slot and the other proximity sensor 163 is near the end position of the guide axle 165 sliding in the limit slot.

When the nursing device is used, when the nursing staff manually pulls out the buckling arm 130, the flexible belt moves outwards along with the buckling arm, the guide wheel 162 is pressed to move inwards, and after the first proximity sensor 163 (corresponding to the leftmost initial position in the limiting slot) senses the flexible belt, the motor rotates reversely to release the flexible belt. When the buckling arm 130 is extended to the proper position, the flexible belt is not pulled, the guide wheel 162 returns under the action of the elastic member 166, and the motor stops rotating after the other proximity sensor 163 (corresponding to the rightmost end position in the limiting slot) senses the rotation of the motor.

In order to solve the problem that the holding force of the hip holding device changes along with the change of the center of gravity in the lifting process of a carrying rider of the shifting machine, the tightening mechanism of the embodiment of the invention further comprises a force sensor for measuring the tightening degree of the flexible belt or indirectly measuring the holding force of the holding arm, the force sensor transmits a measured force signal to the processor, and the processor drives the controller to control the motor and change the winding force and the length of the belt winding wheel, so that a closed-loop control system is formed. The force sensor may be a tension sensor, a pressure sensor, a torque sensor, or the like.

In some embodiments, as shown in fig. 5, a deformation member 171 is interposed between the take-up pulley holder 151 and the rotating arm 120, and is used for changing the distance between the take-up pulley holder 153 and the rotating arm 120 when the tensile force applied to the take-up pulley 153 changes. Wherein, the deformation member 171 is a pressure sensor or the pressure sensor is installed at the deformation member 171. The pressure sensor is used for collecting the pressure between the winding wheel bracket 151 and the fixed rotating arm 120, and the pressure borne by the embracing arm or the applied embracing force can be measured. In some embodiments, the deformation element may be an elastic pad, a spring element, or the like.

In other embodiments, the force sensor may also be a tension-compression type sensor, and in order to enhance the linkage of the clasping arms on the left and right sides, the clasping arms on the left and right sides may also be connected by a rigid structural member, so as to achieve the purpose of simultaneously rotating the clasping arms on the two sides. In an embodiment of the invention, the force sensor may be arranged in a rigid structural part in this place. For example, a deformation member 171 is interposed between the take-up roller holder 151 and the rotation arm 120, and is used to change the distance between the take-up roller holder 153 and the rotation arm 120 when the tensile force applied to the take-up roller 153 changes. Wherein, the force sensor 172 is installed between the supports of the winding wheel 153 at the inner sides of the two side embracing arms through a rigid connecting rod 173.

In the above embodiment, the force sensor may be disposed at the central axis of the winding wheel 153, in which case the force sensor may be a torque sensor, or the force sensor may be disposed at the guide wheel 162 or the guide wheel holder 161, and the displacement of the guide wheel 162 or the guide wheel holder 161 is converted into a force signal, which may also be a feedback signal required for closed-loop control.

According to the tightening mechanism, when the shifter bears a rider to perform displacement in the vertical direction or the horizontal direction in space, the center of gravity is changed due to the change of the angle position, so that the locking effect is poor.
