[0037] Working principle: the medical protection screen for nuclear medicine diagnosis uses when the device protects the patient, the first protection flexible lead plate 4 bottom activity space is the area where the external equipment can work on the patient, in order to make this area can better adjust the area size of itself, the staff need to press the vertical moving rod 11, when the vertical moving rod 11 is pressed, the angle adjusting rod 9 on the surface of the second fixed ring 10 inside the movable column will be displaced, the angle adjusting rod 9 and the plug-in column 8 cooperate, the auxiliary plug-in column 8 can drive the first fixed ring 7 to move horizontally, the first fixed ring 7 moves horizontally finally drives the horizontal moving rod 6 to move horizontally, so that the first protection flexible lead plate 4 can be inside the activity slot 3, and then change the area of the patient's work area of the external equipment, when the device needs to be fine to the patient's certain part, the staff first rotates the rotating rod 14, the rotating rod 14 rotates and drives the convex threaded rod 13 to rotate, because the thread on the surface of the convex threaded rod 13 is convex, the moving block 15 connected with the surface thread of the convex threaded rod 13 can translate inside the limiting frame 12, when the moving block 15 translates, it will drive the fixed shaft 16 to displace, the displacement of the fixed shaft 16 will change the angle of the movable clamping rod 17, because the angle of the movable clamping rod 17 changes, it will drive the auxiliary rod 18 and the movable column inside the second fixed ring 10 to rotate, so the angle adjusting rod 9 drives the plug-in column 8 to rotate, when the staff press the vertical moving rod 11, the distance of the horizontal moving rod 6 can be changed under the condition that the vertical moving rod 11 moves vertically by the same distance, so as to adjust the area of the working area at the bottom of the first protection flexible lead plate 4, at the same time of rotating the rotating rod 14, the worm 19 on the back of the rotating rod 14 rotates from bottom to top, because the thread shape on the surface of the worm 19 is special, the worm 19 rotates from bottom to top, which will drive the worm wheel 20 to rotate from left to right, so the fixed block 28 will be perpendicular to the horizontal moving rod 6 under the drive of the worm wheel 20, finally it can work better on the surface of the first protection flexible lead plate 4, under the rotation of the worm wheel 20, the first limiting disc 27 will rotate, the first connecting sleeve 25 will limit the first limiting disc 27 and the fitting working rod 26 at its bottom, because the device itself is hoisted, under the action of the gravity of the fitting working rod 26 and the rotation of the first limiting disc 27, the fixed rod 29 will move inside the second connecting sleeve 30, the third connecting rod 32 and the rotating shaft 33 on the surface of the second connecting sleeve 30 are used to provide space for the fitting working rod 26, so that the fitting working rod 26 can move in a circle under the action of its own gravity, the fitting working rod 26 moves in a circle between the first protection flexible lead plate 4, the fitting working rod 26 and the patient are fitted under the action of its own gravity,The adjusting spring 34 inside the first limiting disc 27 provides a counterforce to the fitting work rod 26 when it is working, which helps the fitting work rod 26 to control the pressure on the first protective flexible lead plate 4, so that the first protective flexible lead plate 4 can be fitted to the patient's body. The second protective flexible lead plate 35 protects the lower body of the patient. The first and second plug-in plates 37 and 38 limit the movement of the horizontal moving rod 6 and the vertical moving rod 11, so that the horizontal direction of the horizontal moving rod 6 and the vertical direction of the vertical moving rod 11 will not change.
