The working principle is as follows:

the specific operation process for turning over the back of a patient to be examined is as follows:

firstly, the first handle 4 is rotated to drive the first gear 3 to rotate, the first gear 3 drives the second gear 6 to rotate, and the second gear 6 is in threaded connection with the support rod 8, so that the downward regulation of the whole leg lifting mechanism is realized, and a space is left for the optimal position adjustment of the turnover mechanism. The screw is then threaded into the take-up drum 30 until it is threaded into the gear four 12, effecting the securement of the take-up drum 30 to the gear four 12. Then the second handle 33 is rotated, the second handle 33 drives the fourth gear 12 to rotate, the fourth gear 12 moves on the rack 9, and finally when the pushing seat 18 is located at the optimal turning height which is the same as the height of the sickbed, the rotation of the fourth gear 12 is stopped, and then the two hexagonal clamping grooves 29 on the fixing plate 28 are aligned with the third gear 11 and the hexagonal clamping heads 27 arranged on the fourth gear 12 to be clamped, so that the third gear 11 and the fourth gear 12 are meshed and fixed, the fourth gear 12 and the rack 9 are meshed and fixed, and finally the whole turning mechanism is fixed in the vertical direction. Then a belt 26 fixed on the unwinding roll 7 is wound and pulled out, the belt passes through the through hole 17 and enters a first sliding groove 15 arranged on the push plate 16, the belt passes along the first sliding groove 15 below the push plate 16 and then is connected to the unwinding roll 30 by bypassing the fixed pulley 14, and then the screw rod is spirally taken out from the unwinding roll 30 and the gear wheel four 12. Then the pushing seat 18 is slowly put into the waist position of the patient, the second handle 33 is rotated, at this time, the fourth gear 12 is not driven to rotate by the second handle 33, only the winding drum 30 is driven to rotate to wind the belt 26, and half of the force can be saved under the action of the fixed pulley 24 to realize the turning over of the body of the patient. When the winding drum 30 rotates for winding, the belt 26 is pulled, and the belt 26 can drive the push plate 16 to rotate and turn over, so that the patient lying on the push plate 16 can be turned over, the operation is convenient, the structure is simple, half of physical strength can be saved, and a doctor can conveniently check the back of the patient.

The specific operation process for the leg examination of the patient is as follows:

firstly, the screw is screwed into the winding drum 30 until the screw is screwed into the gear four 12, so that the winding drum 30 and the gear four 12 are fixed. Then, the second handle 33 is rotated, the second handle 33 drives the fourth gear 12 to rotate, the fourth gear 12 moves on the rack 9 until the fourth gear 12 contacts the limiting plate 13, or when the fourth gear 12 is at a higher position, the second handle 33 stops rotating, then the two hexagonal clamping grooves 29 on the fixing plate 28 are aligned with the third gear 11 and the hexagonal clamping heads 27 arranged on the fourth gear 12 to be clamped, so that the third gear 11 and the fourth gear 12 are meshed and fixed, the fourth gear 12 and the rack 9 are meshed and fixed, the whole turnover mechanism is finally fixed in the vertical direction, and meanwhile, a space is also reserved for the operation of the leg lifting mechanism. Then rotate handle 4, drive gear 3 and rotate, gear 3 drives gear two 6 and rotates, because gear two 6 and bracing piece 8 are threaded connection, because the spout two 24 and the screw two 25 that are equipped with for shank lifting mechanism can only remove along vertical direction. In addition, after the second screw 25 is taken out spirally, the base plate 5 can be rotated, more space is specially provided for the practicability of the turnover mechanism, and the problem that the two use positions are overlapped to cause inconvenience is avoided. Therefore, the height of the whole leg lifting mechanism is adjusted. Then, a belt 26 wound and fixed on the unwinding roll 7 is pulled out, the belt 26 sequentially passes through a first clamping groove 22 and a second clamping groove 23 which are arranged below the two arc-shaped plates 21, and then the belt is wound around the fixed pulley 24 and is connected to a winding roll 30. Then put two arcs 21 as to between patient's both legs to on putting as to the arc 21 with both legs, then rotate handle two 33, realize the rolling to belt 26, the rolling of belt 26 drives the rising of two arcs 21, thereby realize lifting patient's both legs, the doctor's of being convenient for inspection. The operation is simple and convenient, and the practical use of the fixed pulley 24 can reduce half of physical force, so that the labor intensity of doctors is greatly reduced.

Therefore, the invention can be specially used for lifting the limbs of the patient which can not move independently, when the medical staff inspects the patient, the invention can save half physical strength without the assistance of other people, thereby reducing the workload of the medical staff.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
