Figure 4 The connecting unit 6 comprises a mounting plate 61, a motor 62, a rotating shaft 63 and a fixing hook 64. The mounting plate 61 is symmetrically arranged. Figure 4 As shown, the mounting plates 61 are a pair, and the two mounting plates 61 are fixed relatively to the rear ends of the upper surface of the base plate 1. A motor 62 is installed on the right side surface of the right mounting plate 61, and the output shaft of the motor 62 is fixed on the right end surface of the rotating shaft 63. The left end of the rotating shaft 63 is rotatably connected to the right side surface of the left mounting plate 61, and three corresponding fixing hooks 64 are fixed equidistantly on the surface of the rotating shaft 63.
[0029] The control switch group 8 is installed on the right side of the mounting table 2, and the control switch group 8 is electrically connected to an external power source, and the control switch group 8 is electrically connected to the electric telescopic rod 51. After the motor 62 is turned on, the rotating shaft 63 is driven to rotate, and the rotation of the rotating shaft 63 drives the three fixing hooks 64 to rotate, and the three fixing hooks 64 rotate to pull out the old bed sheet 7 from between the four supporting plates 53 and the patient.
[0030] Specifically, through the above structural setting, the patient is moved by setting the moving unit 5, the patient is supported by setting the supporting unit 3, the height of the patient's head is adjusted by setting the adjusting unit 4, and the old bed sheet is pulled out by setting the connecting unit 6.
[0031] When in use: the four support plates 53 are pulled out, and then the patient is placed on the upper side of the bed sheet 7. When the bed sheet 7 needs to be replaced, the four cover caps 12 are removed. After the cover caps 12 are removed, the air bags 31 shrink, and the shrinkage of the air bags 31 causes the T-shaped block 32 to move downward. When the air bags 31 are completely shrunk, the four electric telescopic rods 51 are controlled to work by the control switch group 8. The four electric telescopic rods 51 work and drive the two connecting blocks 52 to move downward. When the eight slide grooves opened on the sides of the two connecting blocks 52 move to the positions corresponding to the four connecting grooves opened on the upper side of the mounting platform 2, the electric telescopic rods 51 are closed, and then the four support plates 53 are inserted into the inside of the slide grooves and the connecting grooves from right to left in sequence. When inserted into the inside of the connecting grooves, the four support plates 53 are located between the four T-shaped blocks 32 and the bed sheet 7. After the insertion is completed, the four electric telescopic rods 51 are reopened. After the four electric telescopic rods 51 are opened, the four support plates 53 are driven to move upward. The four support plates 53 move upward to put the bed sheet 7 The patient is lifted up, and a new bed sheet 7 is laid on the upper side of the mounting platform 2 again after being lifted up. After laying, the four electric telescopic rods 51 are controlled to retract by the control switch group 8. The four electric telescopic rods 51 retract to make the four support plates 53 move downward. When the four support plates 53 move downward to contact the upper side of the new bed sheet 7, the four electric telescopic rods 51 are closed, and then the motor 62 is turned on. After the motor 62 is turned on, it drives the rotating shaft 63 to rotate. After the four support plates 53 are pulled out, the hydraulic pump 33 is controlled to work by the control switch group 8. The hydraulic pump 33 works to generate compressed gas. The generated compressed gas enters the interior of the four air bags 31 through the connecting pipe 34, the five-way pipe 35 and the four connecting hoses 36. After the compressed gas enters the interior of the air bags 31, the four air bags 31 swell. The swell of the four air bags 31 causes the four T-shaped blocks 32 to move upward to fill the four connecting grooves opened on the upper side of the mounting platform 1. Through the above device, the present invention can very conveniently replace the bed sheet 7.

[0040] Specifically, the bed sheet 7 is fixed by providing the connecting ring 13 and the hook 14 .
[0041] When in use: the four support plates 53 are pulled out through the four pull rings 10, and then the patient is placed on the upper side of the bed sheet 7. When the bed sheet 7 needs to be replaced, the six connecting rings 13 are separated from the six hooks 14, and then the three connecting rings 13 on the rear side are connected to the three fixing hooks 64. After the connection is completed, the four caps 12 are removed. After the caps 12 are removed, the airbags 31 shrink, and the shrinkage of the airbags 31 causes the T-shaped block 32 to move downward. When the airbags 31 are completely shrunk, the four electric telescopic rods 51 are controlled to work through the control switch group 8, and the four electric telescopic rods 51 work to drive the two connecting blocks 5 2 moves downward, when the eight slide grooves opened on the sides of the two connecting blocks 52 move to the positions corresponding to the four connecting grooves opened on the upper side of the mounting platform 2, the electric telescopic rod 51 is closed, and then the four support plates 53 are inserted into the slide grooves and the connecting grooves from right to left in sequence, and when inserted into the connecting grooves, the four support plates 53 are located between the four T-shaped blocks 32 and the bed sheet 7. After the insertion is completed, the four electric telescopic rods 51 are reopened, and the four electric telescopic rods 51 are opened to drive the four support plates 53 to move upward, and the four support plates 53 move upward to lift the bed sheet 7 and the patient, and lift them up. After that, a new bed sheet 7 is laid on the upper side of the mounting table 2 again. After laying, the four electric telescopic rods 51 are controlled to retract by the control switch group 8. The four electric telescopic rods 51 are retracted to make the four support plates 53 move downward. When the four support plates 53 move downward to contact the upper side of the new bed sheet 7, the four electric telescopic rods 51 are closed, and then the motor 62 is turned on. After the motor 62 is turned on, it drives the shaft 63 to rotate. The rotation of the shaft 63 drives the three fixing hooks 64 to rotate. The three fixing hooks 64 rotate to pull the old bed sheet 7 out from between the four support plates 53 and the patient. After pulling out, the old bed sheet 7 is pulled out through the The four pull rings 10 pull out the four support plates 53. After the four support plates 53 are pulled out, the hydraulic pump 33 is controlled to work by controlling the switch group 8. The hydraulic pump 33 generates compressed gas. The generated compressed gas enters the interior of the four air bags 31 through the connecting pipe 34, the five-way pipe 35 and the four connecting hoses 36. After the compressed gas enters the interior of the air bags 31, the four air bags 31 swell. The swelling of the four air bags 31 causes the four T-shaped blocks 32 to move upward to fill the four connecting grooves opened on the side surface of the mounting platform 1. Through the above device, the present invention can very conveniently replace the bed sheet 7.
