[0031] When in use, fix the fixing hoop 50 on the handrail at the edge of the bed and lock it with bolts. The number of the supporting and adjusting mechanisms 4 is determined according to the nursing needs. When installing the supporting and adjusting mechanisms 4, press the opening and closing protrusion 15 with your fingers and pull it backwards. The opening and closing protrusion 15 overcomes the elastic force of the closing spring 14 and slides in the opening and closing slide groove 16. When the front end of the opening and closing protrusion 15 is separated from the closing rotating arm 10, the opening and closing rotating arm 10 rotates outward under the action of the torsion spring, and the two rotating grooves 44 are in a separated state. Then, the opening and closing rotating arm 10 is placed on both sides of the center rod 2. Then, the opening and closing protrusion 15 is released. Under the action of the closing spring 14, the opening and closing protrusion 15 pushes the opening and closing rotating arm 10, and the opening and closing rotating arm 10 rotates inward, so that the center rod 2 is placed in the rotating groove 44 and locked. The screw 45 can fix the opening and closing rotating arm 10 on the central rod 2, and then the elastic rubber tube 18 can be pulled outward according to the care needs, and the elastic rubber tube 18 can be bent in any direction. After the adjustment is completed, the power supply of the electrorheological fluid 20 is turned on. Under the action of the voltage, the electrorheological fluid 20 changes from liquid to solid. Due to the bending, the return spring 19 cannot retract the elastic rubber tube 18. When the power supply of the electrorheological fluid 20 is disconnected, the electrorheological fluid 20 changes from solid to liquid, and the elastic rubber tube 18 restores its original shape. Under the action of the return spring 19, the elastic rubber tube 18 returns to the supporting sleeve 17, and the position and direction of the placement frame 21 can be adjusted arbitrarily. Then the electric telescopic rod 30 is adjusted, and the electric telescopic rod 30 drives the conversion rack 25 to move, and the conversion rack 25 is rotated. The rack 25 drives the conversion gear 28 and the center ring 26 to rotate, the center ring 26 drives the connecting rod 27 to rotate, and the connecting rod 27 drives the outer rotating body 23 to rotate, so that the outer swing groove 39 and the inner swing groove 40 are aligned. When the inner rotating disk rotates clockwise, the locking rod 33 pushes the locking swing plate 31 to the left, the locking swing plate 31 deflects to the left, and the locking rod 33 can pass over the locking swing plate 31. When the inner rotating disk rotates counterclockwise, the locking rod 33 pushes and swings to the right, the locking swing plate 31 deflects to the right, and the locking rod 33 can pass over the locking swing plate 31. At this time, the take-up drum 41 can be arbitrarily reversed to adjust the length of the traction rope 42, and then the support belt is tied to the patient's arm or leg, and then the take-up drum 41 is rotated counterclockwise. The take-up drum 41 reels the traction rope. The guide rope 42, the traction rope 42 pulls the fixed body 43 upward to achieve traction of the support point, and then the electric telescopic rod 30 is adjusted to extend, driving the conversion rack 25 to move left, the conversion rack 25 drives the conversion gear 28 and the center ring 26 to rotate clockwise, the center ring 26 drives the connecting rod 27 to rotate clockwise, the connecting rod 27 drives the outer rotating body 23 to rotate clockwise, the outer rotating body 23 pushes the locking swing plate 31 to swing to the right, the upper end of the locking swing plate 31 is attached to the right side of the inner swing groove 40, the traction rope 42 is in a tensioned state, the traction rope 42 drives the take-up drum 41 to rotate clockwise, when the locking swing plate 31 rotates to the position of the locking rod 33, it is blocked by the locking rod 33, and the traction rope 42 is locked, according to the needs of nursing, repeat the above operation,It is convenient to realize multi-directional traction support for arms, legs and feet.
