[0022] The lifting mechanism 2 comprises two lifting grooves 21, which are respectively arranged on the side walls of the opposite sides of the two fixed plates 12. A threaded rod 22 is rotatably connected in each of the two lifting grooves 21 through a bearing. A threaded sleeve 23 is threadedly connected to the wall of each of the two threaded rods 22. A lifting plate 24 is fixedly sleeved to the outer side wall of each of the two threaded sleeves 23. The opposite ends of the two lifting plates 24 are both extended to the outside of the fixed plate 12 and are fixedly connected to a pressing plate 25. The driving mechanism 3 comprises a mounting cavity 31, which is arranged in the inside of the mounting plate 13. The two threaded rods 22 near the mounting cavity 31 are both extended to the mounting cavity 31 and are fixedly connected to a first bevel gear 32. A double-head driving motor 33 is fixedly installed in the inside of the mounting cavity 31. The two end output ends of the double-head driving motor 33 are both fixedly connected to a driving rod 34 through a shaft coupling. One second bevel gear 35 is fixedly connected to the end of each of the two driving rods 34 away from the double-head driving motor 33. The two first bevel gears 32 are respectively engaged with the two second bevel gears 35. The arm is placed on the placing pad 14 on the placing rack 11 with the palm facing upwards, so that the elbow of the arm is arranged in a front face upwards manner. At this time, the double-head driving motor 33 can be started. The double-head driving motor 33 drives the two driving rods 34 to rotate. The two driving rods 34 drive the two second bevel gears 35 to rotate. The two second bevel gears 35 drive the two threaded rods 22 to rotate through the engagement with the two first bevel gears 32. The two threaded rods 22 drive the two lifting plates 24 to synchronously descend through the cooperation with the two threaded sleeves 23. The two lifting plates 24 drive the pressing plate 25 to vertically descend. The pressing plate 25 stops descending after being about to abut against the arm, so that a certain gap is formed between the pressing plate 25 and the arm.

[0023] The air bag mechanism 4 comprises a receiving groove 41, which is arranged on the inner wall of the bottom end of the pressing plate 25, and an air bag 42 is fixedly installed on the groove wall of the receiving groove 41. The lower surface of the air bag 42 is fixedly connected with a blood pressure measuring patch 43. A connecting hole 44 is arranged through the groove wall of the receiving groove 41.

An annular block 56 is slidably connected in the annular groove 55. The annular block 56 is fixedly sleeved on the rod wall of the fixed rod 52. A spring 57 is sleeved in the annular groove 55. The two ends of the spring 57 abut against the annular groove 55 and the annular block 56, respectively. When the lifting plate 24 descends, the fixed rod 52 will synchronously descend. The fixed rod 52 will be out of abutment against the mounting plate 13. At this time, the spring 57 will push the annular block 56 upwards. The annular block 56 will drive the fixed rod 52 to ascend. The fixed rod 52 will drive the closing plate 53 and the closing plug 54 to synchronously ascend. The closing plate 53 and the closing plug 54 will seal the exhaust port of the pneumatic machine 45. Then the pneumatic machine 45 can be started. The pneumatic machine 45 injects air into the air bag 42 through the connecting hole 44, so that the air bag 42 expands and pushes the blood pressure measuring patch 43 to descend and abut against the front surface of the elbow of the arm, thereby adjusting the arm with different arm circumferences for detection. After use, the double-head drive motor 33 can be started in reverse rotation. The double-head drive belt 33 drives the pressing plate 25 to ascend. At this time, the fixed rod 52 will ascend to abut against the mounting plate 13. The fixed rod 52 will descend in the fixed hole 51 under the support of the mounting plate 13. The fixed rod 52 will drive the closing plate 53 and the closing plug 54 to descend and unseal the exhaust port of the pneumatic machine 45. At this time, the air in the air bag 42 is exhausted through the connecting hole 44 and the exhaust port of the pneumatic machine 45, thereby facilitating subsequent use.

[0024] The bottom end cavity wall of the mounting cavity 31 is fixedly installed with two support plates 36. The two drive rods 34 are rotatably connected to the two support plates 36 through bearings. The support plates 36 support the drive rods 34, thereby avoiding the disengagement of the second bevel gear 35 from the first bevel gear 32 due to distance problems.

[0025] The lower end of the air compressor 45 is provided with an exhaust port, and the position of the exhaust port of the air compressor 45 corresponds to the sealing plug 54 on the sealing plate 53, so that the air can be exhausted through the exhaust port of the air compressor 45 and sealed through the sealing plug 54 on the sealing plate 53.

[0026] In use, first, the arm is placed on the placement pad 14 on the placement rack 11 with the palm upward, so that the front of the elbow of the arm is upwardly arranged, at this time, the double-head drive motor 33 can be started to rotate forward, the double-head drive motor 33 drives the two drive rods 34 to rotate, the two drive rods 34 drive the two second bevel gears 35 to rotate, the two second bevel gears 35 drive the two threaded rods 22 to rotate through the meshing with the two first bevel gears 32, the two threaded rods 22 drive the two lifting plates 24 to synchronously descend through the cooperation with the two threaded sleeves 23, the two lifting plates 24 drive the lower plate 25 to vertically descend, and the lower plate 25 stops descending after being about to abut against the arm, so that there is a certain gap between the lower plate 25 and the arm; the lifting plate 24 drives the fixed rod 52 to synchronously descend when descending, the fixed rod 52 releases the state of abutting against the mounting plate 13, at this time, the spring 57 pushes the annular block 56 upward, the annular block 56 drives the fixed rod 52 to ascend, the fixed rod 52 drives the sealing plate 53 and the sealing plug 54 to synchronously ascend, the sealing plate 53 and the sealing plug 54 seal the bottom of the exhaust port of the air compressor 45, then the air compressor 45 can be started, the air compressor 45 injects air into the air bag 42 through the connecting hole 44, so that the air bag 42 expands and pushes the blood pressure measuring patch 43 to descend and abut against the front of the elbow of the arm, so that the arm with different arm circumferences can be adjusted and detected; and after use, the double-head drive motor 33 can be started to rotate reversely, the double-head drive motor 33 drives the lower plate 25 to ascend, at this time, the fixed rod 52 ascends to abut against the mounting plate 13, the fixed rod 52 is supported by the mounting plate 13 to descend in the fixed hole 51, the fixed rod 52 drives the sealing plate 53 and the sealing plug 54 to descend, and the sealing plate 53 and the sealing plug 54 release the sealing of the exhaust port of the air compressor 45, at this time, the air in the air bag 42 is exhausted through the connecting hole 44 and the exhaust port of the air compressor 45, so as to facilitate subsequent use.
