As shown in FIGS. 1 to 4, the shaft rod 22 is a lightweight, hard tube made of plastic, and its base end is formed to have a diameter slightly smaller than the inner diameter of the handle. Note that the material of the shaft rod is not limited to plastic, and may be natural materials such as rattan, bamboo, and wood, or materials such as ceramic. A feather portion 25 is provided on the outer periphery of the tip of the shaft rod 22. The feather portion 25 is formed by bonding feathers, ie, feathers, synthetic fibers, etc., downwardly with an adhesive so as to be sequentially overlapped along the axial direction of the shaft rod 22.

Note that, as shown in FIG. 7, the shaft rod 22 may have patterns such as letters and figures, advertisements, etc. pasted or drawn on its surface, or the shaft rod may be made into a transparent tubular shape. It's okay. This allows the fluff to be used as a gift or for advertising, further increasing its commercial value. The lower end of the feather portion 25 of this shaft rod is covered with a cap 24.

As shown in FIGS. 1, 2, and 3, the cap 24 is formed in the shape of a funnel with a large diameter at the top, and is wound around the lower end of the feather section 25, that is, the tape 26 of the feather section 25. It is designed to cover parts.

As shown in FIGS. 1 to 5, the handle 23 has a tip 28 formed with a small diameter and a hollow portion 27.
The distal end 28 is formed to have a slightly larger diameter than the outer diameter of the shaft rod 22, and the base end portion of the shaft rod 22 that is fitted into the hollow portion 27 of the handle 23 and is formed to have a larger diameter,
When the shaft 22 is pulled out from the handle 23, that is, when the handle 23 is extended, the base end of the shaft 22 is in contact with the inner surface of the base end 28 of the handle 23, and the base end of the shaft 22 is in contact with the handle. It comes into close contact with the inner surface of the tip 28 of 23, and the shaft rod 22 and handle 23 are fixed in that position due to the close contact force. Therefore, fixing the shaft rod 22 and the handle 23 in the extended state is simply a matter of fixing the shaft rod 22 and the handle 23.
2 from the handle 23, which is extremely simple compared to conventional fixing methods.

The hollow part 27 is a cylindrical hole provided inside the handle 23 along its longitudinal direction, and is
The diameter is larger than the outer diameter of the shaft rod 22 to such an extent that it can be freely inserted.

As shown in FIGS. 2 to 5, the space 30 is the shaft rod 2.

The tip 28 of No. 3 is inserted. 〓
A locking portion 32 is provided on the inner circumferential surface of the proximal end portion of the cap 24 that constitutes the space 30 . This locking part 32
As shown in FIG. 4, the locking portions 32 are protruded from the inner circumferential surface of the proximal end of the cap 24 at intervals, and the portions of the locking portions 32 that are not protruded are connected to the distal end 2 of the handle 23.
This serves as an insertion opening 31 for inserting an engaging portion 35 formed on the outer peripheral surface of 8.

When the handle 23 is to be fixed in a shortened state, the handle 23 is inserted into the gap 30 provided between the shaft rod 22 and the base end of the cap 24, and the engagement formed on the outer peripheral surface of the tip of the handle 23 is inserted. The position of the joint portion 35 is determined by the locking portion 3 that protrudes from the inner circumferential surface of the base end of the cap 24.
By rotating the handle 23 after inserting it in accordance with the position of the insertion opening 31 formed by the
The engaging portion 35 of the handle 23 is engaged with the locking portion 32 within the space 30, and the handle 23 is in a state of being prevented from coming off.

On the other hand, when extending the handle 23, the handle 23 is rotated to release the locked state between the locking part 32 and the engaging part 35, and the insertion opening 31 formed by the locking part 32 is opened.
The engaging portion 35 may be pulled out from the holder.

In this embodiment, the recess 34 inside the base end of the cap 24 has a semicircular cross section, and the shape of the engaging portion 35 is also semicircular in accordance with this. Furthermore, the engaging portions 35 are provided at two opposing positions on the outer peripheral surface of the tip 28 of the handle 23.

(Effects of the Invention) As described in detail above, in the case of the hair duster having a retractable handle of the present invention, when the handle is fixed in a shortened state, the flutter is provided between the shaft rod and the base end of the cap. By inserting the handle between the two and rotating it, the engaging part formed at the tip of the handle is locked by the locking part provided on the inner peripheral surface of the base end of the cap, and the handle is held in place. It is designed to be fixed, so that the shaft and handle do not wobble, the handle does not stretch, or come off during use, making it possible to achieve a secure fixed state.
