The pressurization range is wide, and the areas around the middle area one, middle area two, middle area three and middle area four can be individually converged and pressurized during the pressurization process, as well as coordinated pressurization of different areas. At the same time, each knob can also conveniently and quickly converge the corresponding connecting line, and can accurately control the convergence force when converging. In addition, by flexibly adjusting the placed pressure sensors, the pressure data and pressure results of different swelling positions can be fed back, and with the cooperation of the knobs and the connecting lines, different swelling positions can be pressurized to different degrees.

[0083] Embodiment 2:

[0084] The basic content is the same as that of Example 1, except that:

[0085] See also Figure 4-Figure 6: The number of the pressure sensors 20 in this embodiment is four, including a first sensor 2001, a second sensor 2002, a third sensor 2003 and a fourth sensor 2004; the first sensor 2001, the second sensor 2002, the third sensor 2003 and the fourth sensor 2004 are arranged in any of the following positions: the first type: the first sensor 2001 is located between the hollow sleeve 1 and the upper left sheet 3, the second sensor 2002 is located between the hollow sleeve 1 and the upper left sheet 3, the third sensor 200 3 is located between the hollow sleeve 1 and the upper right piece 4, and the fourth sensor 2004 is located between the hollow sleeve 1 and the upper right piece 4; the second type: the first sensor 2001 is located between the hollow sleeve 1 and the upper left piece 3, the second sensor 2002 is located between the hollow sleeve 1 and the upper left piece 3, the third sensor 2003 is located between the hollow sleeve 1 and the lower left piece 5, and the fourth sensor 2004 is located between the hollow sleeve 1 and the lower left piece 5; the third type: the first sensor 2001 is located between the hollow sleeve 1 and the upper left piece 3, the second sensor 2002 is located between the hollow sleeve 1 and the upper left piece 3, The third sensor 2003 is located between the hollow sleeve 1 and the upper left piece 3, the third sensor 2003 is located between the hollow sleeve 1 and the lower right piece 6, and the fourth sensor 2004 is located between the hollow sleeve 1 and the lower right piece 6; the fourth type: the first sensor 2001 is located between the hollow sleeve 1 and the lower left piece 5, the second sensor 2002 is located between the hollow sleeve 1 and the lower left piece 5, the third sensor 2003 is located between the hollow sleeve 1 and the upper right piece 4, and the fourth sensor 2004 is located between the hollow sleeve 1 and the upper right piece 4; the fifth type: the first sensor 2001 is located between the hollow sleeve 1 The sixth type: the first sensor 2001 is located between the hollow sleeve 1 and the upper right piece 4, the second sensor 2002 is located between the hollow sleeve 1 and the upper right piece 4, the third sensor 2003 is located between the hollow sleeve 1 and the lower right piece 6, and the fourth sensor 2004 is located between the hollow sleeve 1 and the lower right piece 6.

[0089] Embodiment 3:

[0090] The basic content is the same as that of Example 1, except that:

[0091] See also Figure 7-Figure 9: In this embodiment, the part of the hollow sleeve 1 near the first area 11 is connected to the first knob 23, the part of the hollow sleeve 1 near the second area 12 is connected to the second knob 24, the part of the hollow sleeve 1 near the third area 13 is connected to the third knob 25, and the part of the hollow sleeve 1 near the fourth area 14 is connected to the fourth knob 26; the two ends of the first connecting line 7 are fixed in the first knob 23, the two ends of the second connecting line 8 are fixed in the second knob 24, the two ends of the third connecting line 9 are fixed in the third knob 25, and the two ends of the fourth connecting line 10 are fixed in the fourth knob 26; the first knob 23, the second knob 24, the third knob 25 and the fourth knob 26 are connected. The structure and the connection structure of the corresponding connecting line are consistent; the first knob 23 includes a shell 2301, a connecting column 2307 and a rotating block 2305. The bottom end of the shell 2301 is fixed to the first area 11 on the hollow sleeve 1. The connecting column 2307 is slidably inserted into the shell 2301 through the connecting hole 2306 at the top of the shell 2301. The rotating block 2305 is fixed to the part of the connecting column 2307 located outside the shell 2301. The two ends of the first connecting line 7 extend into the shell 2301 through the through holes 2304 on the outer periphery of the shell 2301 and are fixed to the outer periphery of the connecting column 2307. The inner wall of the shell 2301 is close to the bottom wall thereof. The outer wall of the ratchet disc 2302 is connected, and a plurality of tooth grooves 2310 are formed on the inner wall of the ratchet disc 2302 at equal intervals, and a clamping area 2311 is formed between the plurality of tooth grooves 2310. The elastic sheet 2309 is fixed to the outer periphery of the connecting column 2307 close to the bottom wall of the shell 2301, and the vertical projection of the elastic sheet 2309 is located in the clamping area 2311. The elastic sheet 2309 is clamped with the tooth groove 2310 on the ratchet disc 2302. The connecting column 2307 moves vertically in the connecting hole 2306. A rubber ring 2308 is fixed to the outer periphery of the connecting column 2307 located in the shell 2301, and the diameter of the rubber ring 2308 is greater than The diameter of the connecting hole 2306, the connecting column 2307 is located on the outer periphery of the shell 2301, and the take-up wheel 2303 is fixed thereon. The two ends of the first connecting line 7 are fixed on the outer periphery of the take-up wheel 2303. The rubber ring 2308, the take-up wheel 2303 and the elastic sheet 2309 are distributed from top to bottom on the outer periphery of the connecting column 2307 located in the shell 2301. A protruding sheet 2312 is fixed on the outer periphery of the take-up wheel 2303 near its top and bottom. The diameter of the protruding sheet 2312 is larger than the diameter of the take-up wheel 2303. The two ends of the first connecting line 7 are fixed on the outer periphery of the take-up wheel 2303 located between the two protruding sheets 2312.

[0092] When in use, the first connecting line 7, the second connecting line 8, the third connecting line 9 and the fourth connecting line 10 are gathered by the first knob 23, the second knob 24, the third knob 25 and the fourth knob 26, so as to gather the upper left piece 3, the upper right piece 4, the lower left piece 5 and the lower right piece 6 to achieve pressurization. At the same time, the corresponding connecting lines can be gathered by the first knob 23, the second knob 24, the third knob 25 and the fourth knob 26 alone, and partial gathering can be performed to improve the use effect. When the first connecting line 7 is gathered by the first knob 23, the rotating block 2305 is rotated clockwise. After the rotating block 2305 is rotated, the take-up wheel 2303 and the elastic sheet 2309 are driven to rotate in the housing 2301 through the connecting column 2307. When the take-up wheel 2303 rotates, The first connecting line 7 is wound on the take-up wheel 2303 to converge the first connecting line 7. As the first connecting line 7 is converged, the upper left piece 3 and the upper right piece 4 can also complete the convergence to apply pressure to the arm. After the elastic piece 2309 rotates clockwise, the elastic piece 2309 can be deformed in the opposite direction under the action of the tooth groove 2310 on the ratchet disk 2302. After the elastic piece 2309 moves from one tooth groove 2310 to another tooth groove 2310, it will rebound and re-engage with the corresponding tooth groove 2310. Through the cooperation between the elastic piece 2309 and each tooth groove 2310, the first connecting line 7 can be continuously converged. At the same time, because the elastic piece 2309 can only deform in the direction of the connecting column 2307, the connecting column 2307 is Under the restriction of the cooperation of the elastic sheet 2309, the ratchet disc 2302 and the tooth groove 2310, it is impossible to rotate in the opposite direction, and the first connecting line 7 can be always wound on the take-up wheel 2303, and cannot be untied from the take-up wheel 2303 by rotating the rotating block 2305 in the opposite direction; when the first connecting line 7 wound on the take-up wheel 2303 needs to be untied from the take-up wheel 2303, the rotating block 2305 is pulled upward to make the connecting column 2307 move synchronously in the shell 2301. As the connecting column 2307 moves, the rubber ring 2308 on the outside of the connecting column 2307 is squeezed through the top wall of the shell 2301 to make it deform. When the connecting column 2307 is moved to allow the rubber ring 2308 to move out of the shell 2301 through the connecting hole 2306, the shape When the deformed rubber ring 2308 loses the squeezing force, it can rebound and reset, and fall on the top of the shell 2301, to support the connecting column 2307 after it moves upward, so that the connecting column 2307 can maintain this state after being moved out of the shell 2301. As the connecting column 2307 moves, the elastic sheet 2309 will move out of the tooth groove 2310 and release the restriction that the connecting column 2307 cannot rotate in the reverse direction. At this time, the connecting column 2307 can rotate in the reverse direction, allowing the take-up wheel 2303 to rotate in the reverse direction, so that the first connecting line 7 can be untied from the take-up wheel 2303. In addition, after a certain length of the first connecting line 7 is released from the take-up wheel 2303, the connecting column 2307 and the elastic sheet 2309 can be reset to restrict the take-up wheel 2303 again.

[0096] During use, after squeezing the arm by contracting the upper left piece 3, the upper right piece 4, the lower left piece 5, and the lower right piece 6, the pressure data and the pressure result can be fed back according to the placed pressure sensor 20, and the first airbag 305, the second airbag 405, the third airbag 505, and the fourth airbag 605 can be inflated according to the fed back pressure data and the pressure result to perform pressurization fine-tuning. When inflating, after connecting the inflation nozzle 306 to the external gas filling device, the first airbag 305 is inflated, and the first airbag 305 can squeeze the arm, and the first airbag 305 extends along the direction of the upper left free edge 302, and can perform vertical pressurization. Combined with the lateral squeezing of the upper left piece 3, the arm can be better pressurized. After the pressurization work is completed, the gas in the first airbag 305 can also be emptied through the inflation nozzle 306 for subsequent use.
