Description

[Detailed Description of the Invention] Technical field This invention relates to a holder, and a holder that can be attached to and detached from a pair of support arms with numbered numbers on the right side of the holder, and can move +01 within a certain angle. The present invention relates to an oscillating safety razor comprising a supported blade cartridge.

Prior Art Conventionally, in this type of safety razor, one
As disclosed in Japanese Patent No. 151981, the halter is provided with a pushbutton for tilting the replaceable blade cartridge. Therefore, if you do not use a pusher such as a coil spring on the holder,
The biasing means had to be inserted (the structure of the halter had become very complicated).Furthermore, the pusher was in elastic contact with the pressing surface formed in the center of the replaceable blade cartridge. When using a safety razor, although the pair of support arms supports the left and right sides of the blade cartridge 1-ridge, the blade cartridge tends to snap off considerably relative to the support arms, and the butcher does not hold the blade in place. Car 1 - To press the center position of the ridge, the replaceable blade car 1 covers the suppression part at the center.
~The downward swing of the rod is large, and J3+ is caused during use.
The opening force of the car 1 to the tilting movement of the ridge was unsteady and the people were unsteady.

[1] The 1:1 aspect of the present invention is that in addition to eliminating the butt shear, a predetermined replaceable blade car 1 is provided between the supporting arm and the replaceable blade cartridge.
-By setting up the ridge force means, it is possible to simplify the holder's adjustment, and also to improve the stability of the ridge. That's it (・kii) Spare blade: JJ-T Ridge's support city j;? It's about offering.

The present invention has achieved the first objective of the present invention, and the above-mentioned replaceable blade cartridge 4 is tilted so as to be strong. #w

If you want to support the replaceable blade cartridge 1 on the halter 18 made (14), press operation ff4J21 to hear the skin holding arm 19, and move this support arm 19 between the replaceable blade car 1 and the cartridge 1. The support hook portion 19a is inserted into the support hole 8 of the replaceable blade cartridge 1 through the gap S between both 4° portions 3a.
Release the μ, #, f+ buttons 21 facing the -C to close one support arm and engage the support 1.5 hook portion 19a into the support hole 8. In this state, as shown in FIG. 5, the plate of the replaceable blade car 1 hinge 1 is in the spring part 5 a3, and one side edge of the inclined surface 6a of the pressing end 6 abuts against the support arm 19 and is bent. Due to the elastic force exerted on the plate (J, thread 5), the replacement blade car 1-ridge 1 is moved until the support arm 19 comes into contact with the stopper protrusion 9 of the replacement blade car 1-ridge 1. It leans forward around the support hook part 19a.

C. When the safety razor is used with the operation part A Δ31 of the Porgoo 18 moved as shown in FIG. Against the elasticity of the leaf spring portion 5, the meat skin holding arm 19 is tilted backwards in the direction of the arrow Δ in FIG. When not in use, the cartridge 1 returns to the state shown in FIG.

Effects According to the present invention described in detail below, as described above, between the support arm 19 and the replaceable blade cartridge 1, there is provided a plate bone portion 5 that biases the replaceable blade cartridge 1 so as to be able to move inward. By means of the two features, the structure of the holder 18 can be bent (and, moreover, during use) the stability of the replaceable blade car 1-ridge 1 can be improved. Rir.
