Further, when the cleaning is performed in the state of FIGS. 3A and 3B, since the hooking portion 107 is of a sliding type, a built-in spring may be used, and the telescopic extension tube side connection side of the gripping tube 102 is often pushed and gripped. And avoid the structure of moving back and forth swaying.

Here, even when the hook portion 107 is moved to the hose connection side as shown in Fig. 1, once the hook portion 108 is hooked and fixed to the end opening portion 108 of the telescopic extension tube 103, the weight of the hose itself can be utilized. When the hook portion 107 is slid on the connection side of the telescopic extension tube side, a small-sized storage state in which the storage height is suppressed can be automatically formed.

When the hook portion 107 is disposed at the distal end of the telescopic extension tube connection side of the grip operation tube 102, it can be accommodated for further miniaturization.

In the 5A, 5B, and 5C, the shape of the hook portion is shown. In order to allow the hook portion 107 to be easily inserted into the end opening portion 108 of the telescopic extension tube 103, the front end 502 has a large R shape. Further, the inner circumferential surface 504 of the front end 502 of the hook portion 107 is formed into a cylindrical shape along the end opening portion 108 of the telescopic extension tube 103, and it is considered that the end opening portion 108 of the telescopic extension tube 103 is not easily damaged. .

Here, an explanation will be given when the grip operation tube 102 is removed. In Fig. 6, the operation when the grip grip operation tube 102 is twisted and removed is shown. When the cleaning is performed, the user detaches the hook portion 107 from the end opening portion 108 which is the front end of the telescopic extension tube 103, and connects the telescopic extension tube 103 and the grip operation tube 102 to form the second drawing.

The operation of hooking the end opening portion 108 of the telescopic extension tube 103 and shaking the hose 101.

As described in the foregoing description, since the hook portion 107 can be moved 360 degrees along the end opening portion 108 of the telescopic extension tube 103, it is formed that the hook portion 107 is formed even if the hose 101 is shaken to some extent. It is also not easy to fall off the structure.

However, as long as the rotary hook portion 107 is used and the action of the hose 101 as indicated by the arrow 901 is formed, since the grip operation tube 102 and the hook portion 107 form a rotatable structure, the hook can be further prevented. The portion 107 is detached, and a vacuum cleaner having good usability can be provided.

Further, since the grip operation tube 102 is swung left and right, the operation such as twisting cannot be transmitted to the distal end of the hook portion 107, so that the damage of the hook portion 107 can be suppressed.

In Fig. 10, a state in which the auxiliary suction port such as the suction port 1001 is fixed to the hook portion 107 is shown. Conventionally, the gap suction port 1001 and the like are often housed on the side surface of the telescopic extension tube 103, and the gap suction port 1001 is touched during the cleaning, and usually falls off.

In the present embodiment, since the gap suction port 1001 can be fixed to the hook portion 107, it is not easily touched by the sweeper and the wall surface during the cleaning, and the gap suction port 1001 can be prevented from falling off.

Further, in the cleaning, since the gap suction port 1001 is disposed in the vicinity of the grip, it is possible to easily attach and detach even when the gap is removed. By accommodating the gap suction port 1001 on the side surface of the telescopic extension tube 103, the hook portion 107 can be used for small size storage.
