[0037] Working principle and usage process of this utility model:

[0038] When wearing the one-piece protective suit, the first adjustment is made according to the suit's model. The electric push rod 104 moves the adjusting block 110, which in turn moves the central support frame 101. The central support frame 101 then moves the first horizontal frame 102 and the second horizontal frame 108. The first horizontal frame 102 moves the first cuff fixing frame 103, and the second horizontal frame 108 moves the second cuff fixing frame 107, adjusting their heights. Then, the first drive motor drives the drive bevel gear 117, which in turn drives the driven bevel gear 118. The driven bevel gear 118 then drives the bidirectional lead screw 111, causing the first lead screw nut 113 and the second lead screw nut 115 to move in opposite directions. These movements in turn cause the first connecting rod 112 and the second connecting rod 116 to move in opposite directions. 6 drives the first horizontal frame 102 and the second horizontal frame 108 to move in opposite directions, and adjusts the distance between the first cuff fixing frame 103 and the second cuff fixing frame 107, fixing the cuffs of the one-piece protective suit in the first cuff fixing frame 103 and the second cuff fixing frame 107, fixing the trouser cuffs in the trouser cuff fixing frame 3, and then clamping and fixing the thighs of the one-piece protective suit by the elastic clip 26. The second motor 7 drives the longitudinal lead screw 21 to rotate, and the longitudinal lead screw seat 22 facilitates the putting on and taking off of the suit. The frame 24 moves downward, and the donning and doffing frame 24 drives the bearing plate 9 to move downward through the connecting rod 105. As the donning and doffing frame 24 moves downward, the legs of the one-piece protective suit are retracted, and the crotch donning and doffing opening is placed in the position of the donning and doffing frame 24. The medical staff puts their legs through the protective suit legs inside the trouser leg fixing frame 3. The donning and doffing frame 24 is lifted by the longitudinal screw rod 21, and the elastic clip 26 lifts the protective suit legs and puts the protective suit on the medical staff's legs. Then the medical staff can put on the arms.

[0039] When removing the protective suit, firstly, the cuffs of the one-piece protective suit are fixed by the first cuff fixing bracket 103 and the second cuff fixing bracket 107, the trouser cuffs are fixed in the trouser cuff fixing bracket 3, and the arms are taken out of the protective suit. Then, the elastic clip 26 is fixed at the thigh position of the protective suit. The longitudinal screw 21 is rotated to drive the donning and doffing frame 24 to move downward. The donning and doffing frame 24 moves downward through the elastic clip 26 and removes the legs of the protective suit from the legs of the medical staff. Then, the feet are taken out of the protective suit.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
