[0043] Specific usage and function of this embodiment: In the present invention, when drawing blood, the patient's arm is placed on the rubber pad 102 through the arc-shaped support plate 101, and then the control handle 107 is rotated to make the control handle 107 drive the connecting plate 106 to rotate. During the rotation of the connecting plate 106, the lifting screw 105 is driven to rotate. During the rotation of the two lifting screws 105, the lifting slide plate 104 is driven to move. During the movement of the lifting slide plate 104, the installation vertical plate 133 is driven to move. As the installation vertical plate 133 is moved, The movement of the hard rubber strip 134 drives the hard rubber strip 134 to move, so that the hard rubber strip 134 contacts the patient's arm and squeezes the patient's arm, so that the patient's blood vessels are visible. At this time, the medical staff can draw blood from the patient; after the blood drawing is completed, the medical staff reverses the lifting screw 105 to lift the hard rubber strip 134, and supports the arc-shaped supporting plate 101 by installing the bottom plate 1. When the control handle 107 on one side is turned, the synchronous control pulley 108 on the same side will be driven to rotate, and the rotation of the synchronous control pulley 108 will drive the other side through the transmission belt. The synchronous control pulley 108 rotates, and then the rotation of the synchronous control pulley 108 on the other side drives the control handle 107 on the other side to rotate, so that no matter which side of the control handle 107 the medical staff rotates, the two control handles 107 will rotate at the same time. After the blood drawing is completed, the medical staff moves the installation slide 112 by toggling the installation slide 112. During the movement of the installation slide 112, the guide slider 114 will be driven to slide in the guide slot 113 to provide guidance for the installation slide 112 to ensure that the installation slide 112 slides stably, and the position of the pressing plate 116 is adjusted by sliding the sliding seat 112, so that the pressing plate 116 is aligned with the patient's blood drawing position. After the pressing plate 116 is aligned with the patient's blood drawing position, the medical staff places the cotton ball at the patient's blood drawing site, and then rotates the feeding screw 115 to make the feeding screw 115 drive the pressing plate 116 to move, so that the pressing plate 116 squeezes the cotton ball. At the same time, the setting of the squeezing convex point 117 can make the pressure act more concentratedly on the blood drawing point or around the bleeding point, forming a local high-pressure area.This concentrated pressure helps to seal the blood vessel rupture faster, reduce blood outflow, and improve the effect of hemostasis. As the feed screw 115 is screwed in, the auxiliary lifting plate 118 is driven to move. During the movement of the auxiliary lifting plate 118, the guide slide 119 is driven to slide in the mounting slide 112 to provide guidance for the auxiliary lifting plate 118. After hemostasis is completed, the reverse movement of the feed screw 115 drives the auxiliary lifting plate 118 to move upward. As the auxiliary lifting plate 118 moves, the first extrusion wedge 120 is driven to move. As the first extrusion wedge 120 moves, the extrusion of the second extrusion wedge 121 is slowly released. As the first extrusion wedge 120 moves, the second extrusion wedge 121 is slowly released. After block 120 releases the extrusion on the second extrusion wedge block 121, the second extrusion wedge block 121 will reset as the connecting spring 124 rebounds. At the same time, the setting of the connecting slide rod 123 will provide guidance for the second extrusion wedge block 121 to ensure the resetting effect of the second extrusion wedge block 121. During the resetting process of the second extrusion wedge block 121, the sealing shell 125 will be closed to seal the pressing plate 116. As the two sealing shells 125 are closed, the pressing plate 116 will squeeze the control pressing block 129. After the control pressing block 129 is squeezed, it will drive the piston slide rod 127 to slide in the piston sleeve 126 and stretch the fixing spring 128.

[0046] Specific usage and function of this embodiment: In the present invention, during the sliding process of the piston slide rod 127, the liquid storage tank 130 will be pressurized through the pressure tube 131, so that the disinfectant in the liquid storage tank 130 is pressed into the spray pipe 132 and the disinfectant is sprayed into the closed sealing protective shell 125 by the spray pipe 132 to disinfect the pressing plate 116.
