As shown in fig. 2, after the connecting portion 21 is inserted into the first air transmission portion 12, one surface of the sealing member 4 close to the connecting portion 21 can abut against the flange 121, so that the sealing member 4 and the elastic body 1 are tightly connected, thereby playing a role of sealing, and improving the sealing performance and the air blowing effect of the air blowing tool.

Referring to fig. 4, in order to further improve the sealing performance of the air blowing tool, three fastening members 5 are provided on the outer wall of the connection portion 21, the fastening members 5 are ring-shaped, and the fastening members 5 protrude from the outer wall of the connection portion 21. As shown in fig. 2, after the connecting portion 21 is inserted into the first gas transmission portion 12, the fastening member 5 enters the first gas transmission portion 12 along with the connecting portion 21, and an outer wall of the fastening member 5 can abut against an inner wall of the first gas transmission portion 12, so that the connecting portion 21 and the first gas transmission portion 12 are in interference fit.

Referring to fig. 2 and 4, the plurality of fastening members 5 form a multi-layer air flow barrier, so that the sealing performance of the blowing tool is better, and the fastening members 5 indirectly increase the contact area and the friction force between the connecting portion 21 and the first air delivery portion 12, which facilitates the more stable installation of the discharged air 2 on the elastic body 1, and ensures the normal performance of the air outlet function of the discharged air 2. In addition, a groove 23 is formed between the sealing element 4 and the fastening element 5 closest to the functional part 22, the connecting part 21 is inserted into the first gas transmission part 12, and the rear flange 121 is just embedded into the groove 23 and abuts against the connecting part 21, so that the exhaust gas 2 is clamped in the elastic main body 1, and the installation of the exhaust gas 2 on the elastic main body 1 is more stable.
