Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a shaft-attaching device for haircutting scissors used in hairdressing and beauty treatment.

[Conventional technology]

Generally, as shown in FIG. 4, the barber scissors axially mounts the stationary blade 1 and the moving blade 2, but this axial mounting is conventionally provided on the stationary blade 1 and the moving blade 2 as shown in FIG. Shaft bolts 3 and 4
It is inserted through and is tightened with the nut 16. Further, in general, the scissors are provided with a warp in the lengthwise direction and the widthwise direction of the blade so that the stationary blade 1 and the moving blade 2 intersect with each other in a point contact in order to improve the shearing action thereof. There is play between them. Therefore, as shown in FIG.
In particular, a considerable gap a is formed at the shaft-attached portions of the two blades 1 and 2.

[Problems to be solved by the device]

In the above-mentioned conventional haircutting scissors, since there is a considerable gap a in the shaft-attached portions of the two blades 1 and 2, hair scraps and fats and oils will accumulate in the gap a while the hair is being cut. As a result, it becomes difficult to cut the hair and the scissors become less sharp. Therefore, in the past, sometimes the shaft was disassembled and disassembled and cleaned,
At the same time, it was designed to be refueled with rust, which was troublesome.

The present invention solves such problems in conventional haircutting scissors and provides haircutting scissors capable of easily removing hair dust and the like accumulated in the gap a, cleaning and refueling without disassembling the scissors. It is what

[Means for Solving the Problems]

The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to the embodiment. In the present invention, the stationary blade 1 and the moving blade 2 are rotated by an axial bolt 5. In the scissors freely coupled, a recessed hole 9 is provided in the enlarged head portion 7 of the shaft bolt 5 and communicates with the recessed hole 9 to open in the gap a between the stationary blade 1 and the moving blade 2 in the shaft mounting portion. Circulation hole 1
1, 11 are provided, and a plug 12 is detachably fitted in the recessed hole 9.

[Action]

The haircutting scissors according to the above-described device of the present invention are normally used by fitting the plug 12 to the shaft bolt 5 as shown in FIG. And
When hair debris or the like accumulates in the gap a between the stationary blade 1 and the moving blade 2, or when rust prevention or oil supply is required, as shown in FIG.
The spray nozzle with rust prevention and lubricant etc.
17 is inserted into the inflow hole 10 of the shaft bolt 5, and the fluid is injected. As a result, the fluid flows out from the flow holes 11, 11 into the gap a, and the jet flow discharges the dust and debris in the gap a to the outside. At the same time, rust prevention and lubrication will be applied.

〔Example〕

An embodiment of the device of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, 1 is a stationary blade, 2 is a moving blade, and shaft holes 3 and 4 into which shaft bolts 5 to be described later are inserted are attached to their shaft attachment portions.
Is provided. The shaft bolt 5 is provided with a dish-shaped enlarged head portion 7 at one end of the shaft portion 6, and a screw rod portion 8 having a smaller diameter than the shaft portion 6 is projectingly provided at the other end of the shaft portion 6. A large-diameter concave hole 9 and a small-diameter through hole 10 are formed at the outer end of the enlarged head 7 so as to reach the intermediate portion of the shaft portion 6. Connected to the end, static blade 1 and moving blade 2
The flow holes 11, 11 opening in the gap a between the and are radially opened. An elastic plug body 12 made of synthetic rubber or the like is provided, which is provided separately from the shaft bolt 5 and is provided with a lid portion 13 tightly fitted in the recess 9 and a leg portion 14 fitted in the insertion hole 10. Is the first
As shown in the figure, the leg 14 and lid 13
It is provided so that it can be fitted into and removed from the recess 10 and the recess 9.

The present invention is configured as described above, and the shaft bolt 5 is inserted into the shaft holes 3 and 4 of the stationary blade 1 and the moving blade 2, and the leaf spring 15 is engaged with the rod rod 8 protruding from the moving blade 2. Then, the nut 16 is screwed and the tightening stationary blade 1 and the moving blade 2 are axially attached. At that time, the through holes 11, 11 of the shaft bolt 5 are formed in the gap a between the two blades 1, 2.
It is designed to open inside. Then, when using the scissors, as shown in FIG. 1, the concave hole 9 and the through hole 10 of the axial bolt 5 are closed and the plug body 12 is fitted, and hair scraps or the like are put in the gap between the two blades 1 and 2. When it has accumulated, the plug 12 is removed, and as shown in FIG. 3, the nozzle 17 such as a rust preventive or a spray containing a lubricant is inserted into the through hole 10 and the fluid is injected. Then, the fluid flows out into the gap a through the respective flow holes 11, 11, and the hair scraps and the like accumulated in the gap a by the jet flow are discharged to the outside of the scissors. Further, the jet flow serves to prevent rusting and oil supply to both opposite sides of the blades 1 and 2.

[Effect of device]

As described above, in the device of the present invention, in the scissors in which the stationary blade and the moving blade are rotatably coupled by the shaft bolt, the enlarged head portion of the shaft bolt is provided with the recessed hole and is communicated with the recessed hole. A through hole is provided in the gap between the stationary blade and the moving blade in the shaft mounting portion, and the plug body is detachably fitted in the recessed hole. When dust or the like is accumulated, the plug body is removed and a spray nozzle is inserted to eject the dust, so that the accumulated dust and debris can be removed and cleaned, and rust can be prevented and oil can be supplied. Therefore, unlike the conventional scissors, it is not necessary to disassemble the scissors and remove hair debris, clean and refuel each time, and there is an advantage that troublesome maintenance work of the scissors is significantly reduced.
