As the engaging projection 16 is inserted into the hole 15, each extension tube 13 is connected to each other.

In addition, the connection pipe (12a) formed integrally with the inlet (12) is installed another resilient projection (16a) with another leaf spring (not shown), so that the other one of the extension pipe 13 of the extension pipe (13) The extension pipe is connected to the connection pipe 12a of the suction port 12 as it is fitted into the hole 15 formed in the hole 15.

And the handle 14a formed on the human body formed in the extension hose 14 and another hole 15a is formed so that the locking projection 16 is elastically installed with the leaf spring 17 on the other end of the extension pipe 13 is another The extension tube 13 is connected to the handle 14a of the extension hose 14 as it fits into the hole 15a.

Therefore, when a vacuum cleaner is used, a plurality of extension hoses 13 should be connected between the inlet 12 and the extension hose 14, and when not in use, a plurality of extension hoses 13 may be coupled between the inlet 12 and the extension hose 14. The extension tube 13 must be disassembled, and the reason for disassembling the extension tube 13 is to prevent the auxiliary space from being used more widely than necessary when storing the vacuum cleaner.

First, the process of combining the plurality of extension pipes 13 is one extension pipe of each of the extension pipe 13 pushes the locking projections 16 formed on the other side downward and the locking projections move while receiving the elasticity of the leaf spring 17 extension pipe ( The outer circumferential surface of the 13) and the upper end of the engaging projection 16 is coincident. In this state, when one of the other extension tube is pushed into the other extension tube, the hole 15 formed at one side of the other extension tube is leaf spring. Since it is inserted into the hole 15 at the moment coinciding with the locking projection 16 which has been moved while receiving the elasticity of 17, one extension tube and the other extension tube are connected to each other and the plurality of extension tubes 13 are repeated as such. ) Are connected to each other.

In this manner, once the plurality of extension pipes 13 are connected to each other, one of the extension pipes 13 of the plurality of extension pipes 13 is connected to the connection pipe 12a formed integrally with the suction port 12 and the other extension pipe is connected to the extension hose 14. It is to be connected to the integrally formed handle (14a), in this case by pushing another locking projection (16a) elastically installed by another leaf spring in the connecting pipe (12a) down the another locking projection of the plurality of extension pipes (13) The locking projection 16 is formed on the handle 14a by pushing downward the locking projection 16 that is elastically installed with the leaf spring 17 on the other extension tube. What is necessary is just to be clamped in the other hole 15a.

On the other hand, when disassembling the plurality of extension pipes 13 may be reversed to the time of coupling of the extension pipes described above, the description thereof is considered to be sufficiently understood even if not specifically disclosed.
