It is formed to penetrate in the lateral direction, and a semi-circular insertion groove 130 is formed on the inner surface between the front part and the middle part, and a semi-circular ring-shaped insertion blade 140 is formed in the middle of the insertion groove 130 to protrude. do.

Here, the bar shape refers to a rectangular shape as shown in the drawing, but may be configured to have a circular or other angular shape.

In addition, the bolt fitting hole 120 has the same diameter as the fixing bolt 150 to be described later at the top and bottom, and is composed of a long groove having a larger diameter than the fixing bolt 150 in front and behind, the first gripper 100-1 and the second gripper When the (100-2) moves, the fixing bolt 150 is configured to be movable back and forth along the bolt fitting hole 120 .

Meanwhile, in the present invention, as in the above-described embodiment, the first gripper 100-1 and the second gripper 100-2 are formed slightly differently, but as shown in FIG. 6, the first gripper 100-1 and the second gripper 100-2 may be configured to have the same structure.

That is, the first gripper 100-1 and the second gripper 100-2 are each formed in a bar shape, and on the inner surface facing each other at the front, the inclined portion 110 has a narrower width toward the tip. is formed, and in the middle of the inclined portion 110, a bolt-in hole 120 is formed through in the lateral direction. And a semi-circular insertion groove 130 is formed on the inner surface between the front portion and the middle portion, and a semi-circular ring-shaped insertion blade 140 is formed in the middle of the insertion groove 130 to protrude.

Next, the present invention provides a fixing bolt 150 and a fixing bolt 150 that are coupled through the bolt fitting hole 120 to the front of the first gripper 100-1 and the second gripper 100-2. ) is fastened to the end and is configured to include a fixing nut 160 to prevent the fixing bolt from being separated. Therefore, the first gripper 100-1 and the second gripper 100-2 are assembled so that the rear part can be spread and gathered while being guided along the inclined portion 110 with respect to the fixing bolt 150.

According to the present invention, the insertion blade 140 is configured to be inclined on both sides so that the tip end may be sharp, but as shown in FIGS. 2 and 5, one surface is formed as a vertical surface 142 and the other surface is formed as an inclined surface 144. It is preferably formed so that the tip portion is sharp. Then, when the insertion blade 140 digs between the hosel 22 and the ferrule 30 of the head 20 constituting the golf club, the insertion blade 140 and the As the ferrule 30 is pushed together, they are separated from each other. At this time, since the vertical surface 142 is positioned on the ferrule 30 , a phenomenon in which the insertion blade 140 presses the ferrule 30 does not occur, thus preventing the soft ferrule 30 from being damaged.

And the insertion groove 130 is configured to have the same diameter as the ferrule 30 so that a portion corresponding to the vertical surface 142 of the insertion blade 140 can hold the ferrule 30 , and the inclined surface of the insertion blade 140 . The portion corresponding to (144) is configured to have a larger diameter than the hosel (22). Therefore, when gripping the ferrule 30 in the insertion groove 130, the ferrule 30 can be gripped without slipping, and the hosel 22 does not come into contact with the insertion groove 130, thereby preventing scratches and damage. .

Now, a method of using the golf club ferrule separation tool according to the present invention configured as described above will be described.

When separating the ferrule from the hosel of the head constituting the golf club through the present invention, the insertion blade 140 in a state where the first gripper 100-1 and the second gripper 100-2 are spread apart as shown in FIG. 4 . It is positioned between the hosel 22 and the ferrule 30 . Then, holding the first gripper 100-1 and the second gripper 100-2 together with one hand and pressing in the collecting direction as shown in FIG. 3, the insertion blade 140 moves the hosel 22 and the ferrule 30 ), the ferrule 30 is separated while being pushed to one side as shown in FIG. 5 while digging between them. Then, when the first gripper 100-1 and the second gripper 100-2 are hit with a tool such as a hammer, the ferrule 30 is completely separated from the hosel 22 in a simple manner.

On the other hand, the present invention significantly increases hygiene by coating the outer surfaces of the first gripper 100-1 and the second gripper 100-2 with an antibacterial coating solution to maintain antibacterial persistence while suppressing stain resistance and foreign object adhesion. can be improved to make

The antibacterial coating solution applied to the present invention is prepared by mixing copper powder, zinc oxide powder having a particle size of 40 nm, PVC sol, and octamethylcyclotetrasiloxane in a weight ratio of 1.5:1.5:5:2.

Here, copper powder is produced by copper vapor condensation method, and copper vapor condensation method refers to a method of making copper vapor at a high temperature and blowing it out at a low temperature to condense the copper vapor to make it powder. . This copper powder is a powder having a particle size of almost nano size, and has a very strong antibacterial activity as traditionally known. In particular, since copper has ductility, it is very advantageous to maintain flexible properties when manufactured into a film. In addition, zinc oxide powder is a powder containing a zinc component having natural antibacterial properties that has been used for bronze alloys, brass alloys, etc. since ancient times, and it is reported to be very effective in sterilizing particularly Staphylococcus aureus, Pneumococcus pneumoniae, and the like. And PVC sol is a basic raw material resin. And octamethylcyclotetrasiloxane (octamethylcyclotetrasiloxane) is a water-repellent organic material and is added to enhance the anti-fingerprint property by increasing the contact angle to increase the contact angle while increasing the water repellency. In other words, the components of fingerprints and stains are attached by the intermolecular force acting between the surface and the surface. When octamethylcyclotetrasiloxane is contained, the stain adhesion is weakened, and the stain component does not adhere well and fingerprints are not left on the film surface. Contaminants, including other contaminants, do not adhere easily, so it contributes very effectively to suppressing and blocking the spread of infection.

In addition, 20 parts by weight of ommochrome may be further added to the antibacterial coating solution based on 100 parts by weight of the raw material. Ommochrome is a biological pigment group formed by the breakdown of tryptophan, an amino acid, and provides natural preservative and natural antiviral properties. This induces an effective defense mechanism that is harmless to the human body, and it helps to maintain antibacterial durability as it has a characteristic that it remains on the surface of the film for a long time. In particular, Ommochrome is reported to be effective in inhibiting the growth and killing of microorganisms when added to fungi such as Listeria monocytogenes, Salmonella enterica, Staphylococcus aureus, Haemophilus influenzae, and Candida albicans.

As described above, the present invention has been shown and described in relation to specific embodiments, but it is known in the art that various modifications and changes are possible without departing from the spirit and scope of the invention as defined by the claims. When you grow up, everyone will know easily.
