[0017] The present invention has the following beneficial effects:

[0018] 1. According to the present invention, when the rotation of the external threaded sleeve pushes the inner box to rise through the internal threaded sleeve, the external threaded sleeve will pull the middle rod through the pressure spring inside it to make it descend when the installation box rises, and at the same time, it will rotate with the rotation of the external threaded sleeve. When the middle rod rotates with the rotation of the external threaded sleeve, the rotating middle rod will drive the middle shaft and the gear ring to rotate, and the gear ring will drive the four gear sleeves to rotate when rotating. When the gear sleeve rotates, the protrusions on the surface of the protruding rod will slide in the thread groove inside the gear sleeve. When sliding, the protrusions on the protruding rod will make the protruding rod slide downward inside the gear sleeve. When the protruding rod slides downward, it will push one end of the arc plate to move downward through the connecting plate. When one end of the arc plate is pushed downward by the protruding rod, the bottom outer wall of the arc plate will move on the bottom inner wall of the installation box. The triangular plate rotates, and when the arc plate rotates on the triangular plate, the rotation of the arc plate will drive the sliding shaft to move upward. When the sliding shaft moves upward, the end of the sliding shaft away from the arc plate will pull the center of the rubber block to move upward. When the sliding shaft pulls the middle of the rubber block, the rubber block will be pulled by the sliding shaft and the middle part will appear concave. At the same time, the surface of the rubber block will bulge outward. When the middle part of the rubber block bulges outward, the contact area between the installation box and the inner box can be increased, and the friction between the inner box and the installation box can be increased, thereby reducing the movement or shaking of the device during use. At the same time, the rubber block itself has a certain elasticity. When the rubber block bulges outward, it can absorb vibrations from the outside and play a buffering role, thereby reducing the impact of vibrations on the equipment body and improving the accuracy of measurement.

[0019] 2. According to the present invention, when the rotation of the external threaded sleeve drives the intermediate rod to rotate, the rotation of the intermediate rod will drive the intermediate shaft to rotate synchronously. When the intermediate shaft rotates, it will drive the two L rods through the right-angle grooves on its surface, so that the L rods slide inside the piston box. When the L rods slide, the sliding of the L rods will push the piston plate to slide inside the piston box and squeeze the gas inside the piston box. At the same time, when the intermediate rod rotates with the rotation of the external threaded sleeve, the intermediate rod will also drive the grille plate and the tooth plate to rotate. When the grille plate rotates, the grille on its surface will squeeze the air. The gas inside the core ring is blown into the hollow ring, and part of the gas will enter the hollow sleeve at the same time. When the piston plate squeezes the gas inside the piston box, the gas inside it will enter the hollow sleeve through the connecting pipe. Then, when the tooth plate rotates, the tooth plate will drive the gear shaft to rotate inside the hollow sleeve. When the gear shaft rotates, it will drive the auger and the inclined plate to rotate. At this time, the gas entering the hollow sleeve will be transported forward along the spiral structure of the auger under the rotation of the gear shaft. At the same time, when the gas is transported forward inside the hollow sleeve, the gas will be at the connection between the adsorption tube and the hollow sleeve. The opening generates a certain adsorption force, and when the gear shaft drives the inclined plate to rotate, the inclined plate will rotate at the connection port between the adsorption tube and the hollow sleeve. When the inclined plate rotates, the gas inside the adsorption tube will be adsorbed through the rotation of the inclined plate. Since the adsorption tube and the hollow plate are connected, when the gas inside the adsorption tube is adsorbed, negative pressure will be generated inside the hollow plate. After that, when the middle rod rotates and moves downward, the downward movement of the middle rod will drive the rotating ring to move downward synchronously. When the rotating ring moves downward, the rotating ring will push the hollow plate downward, and the hollow plate will also expand outward. When moving downward and expanding outward, the hollow plate will drive the elastic ball to squeeze the inner wall of the inner box. At this time, the elastic ball will be deformed when squeezing the inner wall of the inner box. At this time, the adsorption holes at the bottom of the deformed elastic ball will fit against the inner wall of the inner box. Later, when negative pressure is formed inside the hollow plate, the formation of negative pressure will pass through the adsorption holes at the bottom of the elastic ball, so that the hollow plate and the elastic ball will fit tightly against the inner wall of the inner box, and form an additional fixing force for the installation box, further enhancing the stability of the equipment, thereby improving the accuracy and reliability of the measurement results, and reducing the risks caused by accidental movement of the equipment.

[0020] 3. In the present invention, when the rotation of the intermediate rod drives the grille plate and the intermediate shaft to rotate, the rotation of the grille plate will drive the tooth plate to rotate. When the grille plate rotates, the gas inside the hollow ring will be thrown into the hollow ring, and part of the gas will enter the inside of the hollow sleeve. Then, when the intermediate rod drives the intermediate shaft to rotate, the rotation of the intermediate shaft will drive the L rod to slide downward inside the piston box. When the L rod slides downward, the L rod will squeeze the gas inside the piston box through the piston plate. When the gas in the piston box is squeezed, the gas will enter the hollow sleeve through the connecting pipe. At the same time, when the grille plate drives the tooth plate to rotate, the tooth plate will drive the gear shaft to rotate. When the gear shaft rotates, it will drive the surface auger to rotate. The auger on the surface of the gear shaft rotates, and the gas thrown out by the grille plate and the gas entering the hollow sleeve through the connecting pipe rotate. The rotation of the auger stirs and compresses the gas, which pushes the gas to flow forward and accelerates the flow rate of the gas to a certain extent. At this time, the fast-flowing gas enters the outlet plate through the outlet pipe and is ejected out through the outlet plate. When the gas is ejected, it impacts the inner wall of the inner box and the sliding path of the elastic ball, reducing the presence of dust on the sliding path of the elastic ball and the influence of dust on the adsorption performance of the elastic ball, ensuring that the elastic ball always maintains a stable adsorption force during use to prevent accidental movement of the equipment body during use.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The outer surface of the rotating ring 701 is rotatably connected to a plurality of hollow plates 702. The hollow plates 702 are connected to an adsorption tube 505. The downward movement of the intermediate rod 204 will drive the rotating ring 701 to move downward synchronously. When the rotating ring 701 moves downward, the rotating ring 701 will push the hollow plates 702 to move downward. At the same time, the hollow plates 702 will expand outward.

At this time, the adsorption hole at the bottom of the deformed elastic ball 703 will fit the inner wall of the inner box 102. Afterwards, when negative pressure is formed inside the hollow plate 702, the formation of negative pressure will pass through the adsorption hole at the bottom of the elastic ball 703, so that the hollow plate 702 and the elastic ball 703 are tightly fitted to the inner wall of the inner box 102.

[0046] When in use, first place the installation box 103 inside the inner box 102, and then place the device body 104 on the installation box 103. Then, the height can be adjusted according to the usage of different patients. When adjusting the height of the installation box 103, first start the motor 201. When working, the motor 201 will drive the internal threaded sleeve 203 to rotate through the external threaded sleeve 202. Since the internal threaded sleeve 203 is fixedly connected to the outer wall of the inner box 102, and the inner box 102 is slidably connected to the working box 101, when the internal threaded sleeve 203 rotates, the internal threaded sleeve 203 will push the inner box 102 to rise. When the inner box 102 rises, it will push the installation box 103 and the device body 104 to rise, thereby completing the height adjustment.

[0047] When the rotation of the external threaded sleeve 202 pushes the inner box 102 to rise through the internal threaded sleeve 203, the external threaded sleeve 202 will pull the middle rod 204 through its internal pressure spring to make it descend when the installation box rises, and at the same time, it will rotate with the rotation of the external threaded sleeve 202.

When the protrusion on the protruding rod 305 slides, the protruding rod 305 slides downward inside the gear sleeve 306. When the protruding rod 305 slides downward, it pushes one end of the arc plate 303 to move downward through the connecting plate 304. When one end of the arc plate 303 is pushed downward by the protruding rod 305, the bottom outer wall of the arc plate 303 is on the installation box 10 3, when the arc plate 303 rotates on the triangular plate, the rotation of the arc plate 303 will drive the sliding shaft 302 to move upward. When the sliding shaft 302 moves upward, the end of the sliding shaft 302 away from the arc plate 303 will pull the center of the rubber block 301 to move upward. When the sliding shaft 302 pulls the middle of the rubber block 301, the rubber block 301 will be pulled by the sliding shaft 302, and the middle part of the rubber block 301 will be concave. At the same time, the surface of the rubber block 301 will bulge outward. When the middle part of the rubber block 301 bulges outward, the contact area between the installation box 103 and the inner box 102 can be increased, the friction between the inner box 102 and the installation box 103 can be increased, and the movement or shaking of the device during use can be reduced. At the same time, the rubber block 301 itself has a certain elasticity. When the rubber block 301 bulges outward, it can absorb the vibration from the outside and play a buffering role, reducing the impact of the vibration on the device body 104 and improving the accuracy of measurement.

[0048] Afterwards, when the rotation of the external threaded sleeve 202 drives the intermediate rod 204 to rotate, the rotation of the intermediate rod 204 will drive the intermediate shaft 402 to rotate synchronously. When the intermediate shaft 402 rotates, it will drive the two L rods 403 through the right-angle grooves on its surface, so that the L rods 403 slide inside the piston box 405. When the L rods 403 slide, the sliding of the L rods 403 will push the piston plate 404 to slide inside the piston box 405 and squeeze the gas inside the piston box 405. At the same time, when the intermediate rod 204 rotates with the rotation of the external threaded sleeve 202, the intermediate rod 204 will also drive the grille plate 601 and the tooth plate 602 to rotate. When the grille plate 601 rotates, the grille on its surface will squeeze the air The gas inside the core ring 406 is blown into the hollow ring 406, and part of the gas will enter the hollow sleeve 501 at the same time. When the piston plate 404 squeezes the gas inside the piston box 405, the gas inside it will enter the hollow sleeve 501 through the connecting pipe 502. Then, when the tooth plate 602 rotates, the tooth plate 602 will drive the gear shaft 506 to rotate inside the hollow sleeve 501. When the gear shaft 506 rotates, it will drive the auger and the inclined plate 507 to rotate. At this time, the gas entering the hollow sleeve 501 will be transported forward along the spiral structure of the auger under the rotation of the gear shaft 506. At the same time, when the gas is transported forward inside the hollow sleeve 501, the gas will be transported between the adsorption tube 505 and the hollow sleeve 501. The connecting port generates a certain adsorption force, and when the gear shaft 506 drives the inclined plate 507 to rotate, the inclined plate 507 will rotate at the connecting port of the adsorption tube 505 and the hollow sleeve 501, and when the inclined plate 507 rotates, the gas inside the adsorption tube 505 will be adsorbed through the rotation of the inclined plate 507. Since the adsorption tube 505 is connected to the hollow plate 702, when the gas inside the adsorption tube 505 is adsorbed, a negative pressure will be generated inside the hollow plate 702. After that, when the middle rod 204 rotates and moves downward, the downward movement of the middle rod 204 will drive the rotating ring 701 to move downward synchronously. When the rotating ring 701 moves downward, the rotating ring 701 will push the hollow plate 702 to move downward, and at the same time, the hollow plate 702 will move outward. When the hollow plate 702 moves downward and expands outward, the hollow plate 702 will drive the elastic ball 703 to squeeze the inner wall of the inner box 102. At this time, the elastic ball 703 will be deformed when squeezing the inner wall of the inner box 102. At this time, the adsorption holes at the bottom of the deformed elastic ball 703 will fit against the inner wall of the inner box 102. Later, when negative pressure is formed inside the hollow plate 702, the formation of negative pressure will pass through the adsorption holes at the bottom of the elastic ball 703, so that the hollow plate 702 and the elastic ball 703 are tightly fitted to the inner wall of the inner box 102, and an additional fixing force is formed for the installation box 103, thereby further enhancing the stability of the equipment, thereby improving the accuracy and reliability of the measurement results, and reducing the risks caused by accidental movement of the equipment.

[0049] When the rotation of the middle rod 204 drives the grille plate 601 and the middle shaft 402 to rotate, the rotation of the grille plate 601 will drive the tooth plate 602 to rotate. When the grille plate 601 rotates, the gas inside the hollow ring 406 will be thrown into the hollow ring 406, and part of the gas will enter the hollow sleeve 501. Then, when the middle rod 204 drives the middle shaft 402 to rotate, the rotation of the middle shaft 402 will drive the L rod 403 to slide downward inside the piston box 405. When the L rod 403 slides downward, the L rod 403 will squeeze the gas inside the piston box 405 through the piston plate 404. When the gas in the piston box 405 is squeezed, the gas will enter the hollow sleeve 501 through the connecting pipe 502. At the same time, when the grille plate 601 drives the tooth plate 602 to rotate, the tooth plate 602 will drive the gear shaft 506 to rotate. When 506 rotates, it will drive the auger on the surface to rotate. At this time, the gas thrown outward by the grille plate 601 and the gas entering the hollow sleeve 501 through the connecting pipe 502 will rotate on the surface of the gear shaft 506. The rotation of the auger will stir and compress the gas, which will push the gas to flow forward and accelerate the flow speed of the gas to a certain extent. At this time, the fast-flowing gas will enter the air outlet plate 504 through the air outlet pipe 503 and be ejected outward through the air outlet plate 504. When the gas is ejected, it will impact the inner wall of the inner box 102 and the sliding path of the elastic ball 703, reducing the presence of dust on the sliding path of the elastic ball 703, and reducing the influence of dust on the adsorption performance of the elastic ball 703, ensuring that the elastic ball 703 always maintains a stable adsorption force during use to prevent accidental movement of the equipment body 104 during use.

[0050] After use, the motor 201 is started to reverse. When the motor 201 reverses, the pressure spring between the middle rod 204 and the external threaded sleeve 202 pushes the middle rod 204 to move up and reset for the next use.
