A fast adjustment screw rod 4 is arranged inside the fast adjustment nut 3. A transmission cap 5 is arranged at the top end of the fast adjustment screw rod 4. A slow adjustment nut 6 is arranged at the top of the fast adjustment screw rod 4. A pressing rod 7 penetrates through the inside of the slow adjustment nut 6.
[0024] The top end of the fast adjustment anti-rotation sealing plate 2 is arranged inside the bottom of the fast adjustment nut 3.
[0025] The bottom of the fast adjustment nut 3 is arranged inside the main body support plate 1.
[0026] The fast adjustment screw rod 4 penetrates through the inside of the fast adjustment anti-rotation sealing plate 2.
[0027] The bottom of the slow adjustment nut 6 is arranged inside the transmission cap 5.
[0028] The pressing rod 7 penetrates through the inside of the fast adjustment screw rod 4, and the transmission cap 5 is rotationally connected to the slow adjustment nut 6.
[0029] The outer shape of the top of the fast adjustment screw rod 4 is adapted to the inner shape of the bottom of the transmission cap 5, and the fast adjustment screw rod 4 is fixedly connected to the transmission cap 5.
[0030] The slow adjustment nut 6 is threadedly connected to the pressing rod 7, and the fast adjustment screw rod 4 is threadedly connected to the fast adjustment nut 3.
[0031] The specific implementation method is as follows: When using the present utility model, by rotating the quick-adjusting nut 3, the quick-adjusting screw rod 4 drives the downward pressure rod 7 and the slow-adjusting nut 6 to quickly press down or lift along the axial direction of the quick-adjusting nut 3. By rotating the slow-adjusting nut 6, the downward pressure rod 7 can slowly press down or lift along the axial direction of the slow-adjusting nut 6. The present utility model has the functions of pressing down and lifting during quick adjustment and slow adjustment, can prevent the downward pressure rod 7 from rotating, and the quick-adjusting mechanism and the slow-adjusting mechanism have the anti-loosening and anti-backflow functions after the downward pressure rod 7 is pressed down and tightened. The quick-adjusting screw rod 4 drives other moving parts to press down and lift together. The quick-adjusting screw rod 4 has threads and inner and outer flat squares. The selected thread mechanism can prevent the downward pressure mechanism from retreating after being pressed down and tightened, and has the anti-loosening and anti-backflow functions. The cooperation between the outer flat square and the flat square of the quick-rotation prevention and sealing plate can limit its rotation when the nut rotates. The cooperation between the inner flat square and the flat square of the downward pressure rod 7 has the axial guiding and rotation-limiting functions, and can make the downward pressure rod 7 slide down along the axis. With the structures of the slow-adjusting nut 6, the downward pressure rod 7, and the transmission cap 5, it can be realized that when the slow-adjusting nut 6 is rotated, the downward pressure rod 7 slowly presses down or lifts. The selected thread mechanism of the slow-adjusting nut 6 can prevent the downward pressure mechanism from retreating after being pressed down and tightened, and has the anti-loosening and anti-backflow functions. The transmission cap 5 connects the quick-adjusting structure and the slow-adjusting structure into one body. During quick adjustment, it can drive the slow-adjusting structural parts and the downward pressure rod 7 to lift or press down together. The structure of the present utility model is simple, can realize quick and slow double-speed adjustment, can realize anti-loosening and anti-backflow after pressing down and tightening, and can realize lifting and rotation limitation. The present utility model can be used in various application scenarios that require quick and slow double-speed adjustment, including but not limited to the quick and slow double-speed adjustment scenarios in medical devices or other instruments and meters, and has wide application value.
