Additionally, a tool for tightening the adapter to the faucet includes a serration portion that can be fitted into the tooth portion and a tightening portion, and the serration portion of the tool is engaged with the tooth portion of the adapter for tightening. The adapter is configured to be tightened and screwed into the faucet by manually tightening the attachment part.

The installation tool, which is the second gist, is a tool for screwing an adapter used when installing a water purifier or the like onto the tip of a faucet, and the tool is attached to the inner circumferential surface of the adapter. It is configured to include a serration portion that can be removably fitted into the formed tooth portion and a tightening portion that can be tightened by hand.

(Function) In the first aspect, the adapter has teeth formed on its inner circumferential surface, and when the serrations of the mounting tool are engaged with the teeth, the tightening part of the tool is manually operated. By gripping and tightening the adapter, the adapter is rotated using a tool and can be firmly tightened to the tip of the faucet in the shape of a mirror stand, thereby ensuring good watertightness at the tip of the faucet.

In addition, if you use the installation tool in the second aspect, even if the shape of the faucet is often different, you can fit the serrations into the southern part of the swallowtail better from the lower side and firmly secure the adapter to the faucet. This allows the adapter to be easily and efficiently installed.

(Example) Hereinafter, one embodiment of the present invention will be described based on the inside.

FIG. 1 is a configuration diagram showing a state in which an adapter is attached to the tip of a faucet, and FIG. 2 is an exploded perspective view of the adapter and a tightening tool.

In Figure 1, when attaching a water purifier or the like to the tip of the faucet 1 of the faucet fitting, first screw the threaded part of the adapter 2 into the threaded part formed at the tip of the faucet 1 to integrate it. A cap nut 3 is attached to the adapter 2, a water purifier, etc. (not shown) is connected to the cap nut 3, and the water purifier, etc. is attached to the tip of the faucet 1. It is necessary to tighten the adapter 2 to the tip part in the shape of a mirror stand, and in this example, the adapter 2 and the tightening tool 4 for tightening the adapter 2 are constructed as shown in FIG.

That is, the faucet 1 is provided on the inner peripheral surface of the base 2a of the adapter 2.
A threaded portion 2b that can be screwed is formed on the lower end of the base 2a, a flange 2c is formed in the lower part of the base 2a in a manner that projects laterally, and a flange 2c is formed in the center of the swallowtail 2 in a penetrating manner. A central opening H is formed, and a plurality of tooth portions 2d, 2d, 2d are integrally formed at equal intervals along the inner peripheral surface of the central opening H so as to protrude inwardly.

Further, the tightening tool 4 has a serration portion 4b formed at the upper end of the cylindrical portion 4a, and tooth portions 4c, 4c, and 4e formed at equal intervals forming the serration portion 4b correspond to the tooth portions of the adapter 2. 2d.

It is formed in a shape that can be fitted between 2d. Further, a large-diameter circular tightening section 4d is integrally formed at the lower end of the columnar section 4a, and the outer circumferential surface of the tightening section 4d has 1. A subordinate kerf is formed on its circumference.

The adapter 2 configured in this way is attached to the threaded part of the tip of the faucet 1 like a mirror stand, and the teeth 4C of the serrations 4b of the tightening tool 4 are attached to the teeth 2d, 2d of the Agebuta 2. In the fitted state, the tightening part 4d of the tightening tool 4
