Specifically, the engaging structure 6 includes a rubber block 61, a second spring 62, a sealing ring 63, and an inflation tube 64. The rubber block 61 is slidably connected to the inside of the fixed cylinder 24, and the rubber block and the rubber block described in the 61 The fixed cylinder 24 is sealed, and the second spring 62 is fixed between the top end of the rubber block 61 and the inner top end of the fixed cylinder 24. The elastic force of the second spring 62 is greater than that of the first spring 56, two The air outlet pipes 59a are all connected to the interior of the fixed cylinder 24, and the interior of the fixed cylinder 24 is connected to the two inflation pipes 64, and the two inflation pipes 64 are located between the fixed sleeve 22 and the sweater. Between the body 1, two sealing rings 63 are fixed at the bottom end of the fixing sleeve 22, the sealing ring 63 is located at the top of the sweater body 1, and the two inflation tubes 64 are respectively connected to the two The sealing ring 63, the rubber block 61 is located between the air outlet pipe 59a and the inflation pipe 64, the pressing block 3 is slidably connected with the fixed cylinder 24, the pressing block 3 has good air permeability, The top of the pressing block 3 is located at the bottom end of the inflation tube 64, and the length of the pressing block 3 is greater than the distance between the rubber block 61 and the bottom end of the fixing cylinder 24; in order to make the sweater body 1 When obese people wear a large abdomen and lift their abdomen, when the sweater body 1 is tight, pull the button cap 42 and the fixing sleeve 22 to make the fixing rod 43 squeeze the The elastic piece 58 makes the airbag 53 stretch and inflate. When the sweater body 1 is loose, the fixed rod 43 returns to the original position through the elastic piece 58 to compress the airbag 53, so that the airbag 53 will After the gas is filled into the inside of the sealed cavity 59 and the gas pressure inside the sealed cavity 59 reaches the maximum, the gas enters the inside of the fixed cylinder 24 from the outlet pipe 59a and pushes the rubber block 61, so that the rubber block 61 Slide to the bottom end of the connection between the inflation tube 64 and the fixed cylinder 24, so that the second spring 62 is stretched to generate elastic force, so that the gas enters the inside of the sealing ring 63 through the inflation tube 64, so that the The sealing ring 63 expands and squeezes the sweater body 1 and the fixing sleeve 22, so that the sub button 21 and the fixing sleeve 22 are more tightly fastened on the sweater body 1, further preventing the sweater body 1 from The fixing sleeve 22 is separated from the buckle cap 42, and by pressing the pressing block 3, the pressing block 3 pushes the rubber block 61, so that the rubber block 61 slides between the air outlet pipe 59a and the solid cylinder 24 The top of the communication part is to make the gas inside the sealed cavity 59 enter the inside of the fixed cylinder 24 from the outlet pipe 59a, so that the gas can pass through the gap between the pressing block 3 and the fixed cylinder 24. The fixed block 57 is discharged from the middle by the elastic force of the first spring 56 to return to the original position and disengage from the fixed groove 45, that is, the fixed sleeve 22 can be taken out from the buckle cap 42, which is convenient for taking off the Cardigan body 1.

When in use, first, wear the sweater body 1 on the body of obese people, align the fixing sleeve 22 with the buckle cap 42, make the fixing rod 43 pass through the fixing hole 23 into the through hole 52, and squeeze the buckle 21 and the female buckle 41, make the stopper 44 push the support block 51, make the support block 51 squeeze the air bag 53, make the air bag 53 inflate, and fill the gas from the air delivery pipe 55 into the inside of the sealing cavity 59, so that the gas first pushes the fixed block 57, The first spring 56 is stretched to generate elastic force. After the airbag 53 is completely compressed, the fixed rod 43 enters the inside of the fixed sleeve 22, and when the fixed groove 45 is located at the bottom end of the fixed sleeve 22, the fixed block 57 and the elastic sheet 58 are pushed by the gas. Slide into the fixing groove 45 inside the fixing rod 43, so that the fixing rod 43 is fixed inside the fixing sleeve 22, and through the elastic force of the air bag 53 and the elastic sheet 58, the fixing sleeve 22 and the buckle cap 42 are fixed well and fixed together. Detachment, so that the sweater body 1 will not collapse, and when the sweater body 1 is tightened in the process of the obese people wearing the sweater body 1, pull the buckle cap 42 and the fixing sleeve 22, make the fixed rod 43 squeeze the elastic sheet 58, so that the air bag 53 is stretched and inflated, and the elastic sheet 58 is used to buffer the fixed sleeve 22 and the buckle cap 42 from the tension of the sweater body 1, preventing the buckle cap 42 and The fixing sleeve 22 is suddenly tightened and collapsed. When the sweater body 1 is loose, the fixing rod 43 returns to the original position through the elastic sheet 58 and compresses the air bag 53, so that the air bag 53 fills the inside of the sealed cavity 59 with gas, and the sealed cavity 59 After the internal gas pressure reaches the maximum, the gas enters the fixed cylinder 24 from the outlet pipe 59a to push the rubber block 61, so that the rubber block 61 slides to the bottom end of the connection between the inflatable tube 64 and the fixed cylinder 24, so that the second spring 62 is stretched to generate elastic force , so that the gas enters the inside of the sealing ring 63 through the inflation tube 64, so that the sealing ring 63 expands and squeezes the sweater body 1 and the fixing sleeve 22, so that the buckle 21 and the fixing sleeve 22 are more tightly fastened on the sweater body 1, To further prevent the fixed sleeve 22 from breaking away from the buckle cap 42, by pressing the pressing block 3, the pressing block 3 pushes the rubber block 61, and the rubber block 61 slides to the top of the connection between the air outlet pipe 59a and the solid cylinder 24, so that the inside of the sealed cavity 59 can be sealed. The gas enters the inside of the fixed cylinder 24 from the outlet pipe 59a, and the gas is discharged from the gap between the pressing block 3 and the fixed cylinder 24, so that the fixed block 57 is returned to its original position by the elastic force of the first spring 56 and detached from the fixed groove 45. That is, the fixing sleeve 22 can be taken out from the buckle cap 42, so that the woolen sweater body 1 can be easily taken off.
