The device is characterized by comprising a gap provided between the two and a retaining member 11 provided within the gap.

As shown in Figs. 1 to 4, the shaft rod (22) is a lightweight, hard tube made of plastic;
(The diameter of the end is slightly smaller than the inner diameter of the handle.The material of the shaft is not limited to plastic, but can also be made of natural materials such as rattan, bamboo, and wood, as well as traditional materials such as ceramics. This shaft rod (22) has a feather part (
The feather part (25) provided with the shaft rod (25)
22) Feathers 1, that is, feathers, synthetic fibers, etc., are bonded and formed with an adhesive so as to be successively overlapped in the axial direction.

As shown in Figure 7, the shaft rod (22) may have patterns such as letters and figures or advertisements pasted or drawn on its surface, or the shaft rod may be covered with a transparent material. It may be made into a tubular shape.

This allows the fluff to be used as a gift or for advertising, further increasing its commercial value.

A cap or a cap is attached to the shaft to cover the lower end of the feather portion formed on the shaft.

As shown in Figures 1, 2 and 3, the cap (2
4) is formed in the shape of a funnel with a large diameter from the upper side and covers the lower end of the tiered feather part (25), that is, the part of the feather part (25) wound with the tape (26). There is.

In this way, the base end of the shaft that covers the feather part 41 covered by the cab is inserted into the hollow part of the handle.

As shown in FIGS. 1 to 5, the handle (23) has a base end (28) formed with a small diameter and a hollow portion (27).

The base end (28) is formed to have a slightly larger diameter than the outer diameter of the shaft (22), and has a larger diameter than the shaft (22) inserted into the hollow part (27) of the handle (23). The state in which the shaft rod (22) is pulled out from the handle (23) by the base end portion formed in the.

With the handle (2'l) extended, touch the base end (2'l) of the handle (2]).
The peak-sized base end of the shaft rod (22) comes into contact with the inner surface of the shaft (22), and the base end of the shaft (22) comes into close contact with the inner surface of the base of the handle (23) (28). The shaft (22) and handle (23) are fixed in position by force.

For this reason, the shaft rod (22) and handle (23) in the stretched state
The fixing can be done by simply pulling out the shaft (22) from the handle (23), making it extremely simple compared to conventional fixing methods.

The hollow part (27) is a cylindrical hole provided inside the handle (23) along the opposite direction, and is formed from the outside of the shaft (22) to the extent that the shaft (22) can be freely inserted therein. It is formed to have a larger diameter than the diameter.

Next, the gaps (1i1 and 2 parts a), which are the main parts of this invention, will be explained.

As shown in Figures 2 to 5, the gap (30) is
