Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a device for extracting adjuster pins from watch bands.

<Problems that this invention aims to solve> A watch band that is made up of a large number of pieces connected requires a shaft that uses a C-ring or pawl pipe that can be pulled out between some pieces to hold it in place, hereinafter referred to as adjuster pins. However, there is a problem in that there is no jig that allows anyone to easily perform the extraction operation at a store, which is inconvenient. Even if a jig is made, if the pin is pushed out by simply holding down the space between the pieces in a plane, a problem arises in that the pieces on both sides of the pin open outward from each other due to the extrusion reaction force, making it impossible to pull out the pin. The present invention attempts to solve these problems.

<Structure of the invention> The present invention installs a rotating shaft with a handle that is supported by a bearing member installed on one side across a band insertion passage provided in the middle of the frame body, and is equipped with a handle that rotates back and forth. A push-out shaft for adjusting pins is attached to the front end so as to be replaceable, and a hole for receiving the push-out pin is provided on the other side of the band insertion path, and the curved surfaces on both sides of the hole are different in size. A tool for extracting adjuster pins from a watch band, characterized in that a receiving member is replaceably mounted.

<Example> Examples will be described below based on the drawings.

A watch band A is placed in the middle of a frame body 2 having a bottom plate 1.
An insertion passage 3 is provided through which the material can be freely inserted. Insertion path 3
A metal bearing member 4 is provided across the two sides.
5 is its fixing member. A transverse screw hole 6 is provided in the center of the bearing member 4, and a rotation shaft 8 with a handle 7 is screwed therein. 9 is a threaded portion. A push-out shaft 10 of adjusting pins B is attached to the front end of the rotation shaft 8 so as to be replaceable. On the other side across the insertion path 3, there is a hole 1 in the center for receiving the push-out pins B.
1, and several types of plastic receiving members 13 with curved surfaces 12a and 12b of different sizes on both sides are replaceably mounted. 14 is the exchange port.

Curved surface 12 that matches the shape of piece C of watch band A
Select the receiving member 13 having the pins a and 12b, slide it in from the replacement port 14, align the adjusting pin B to be removed with the center of the push-out pin 10, and place the watch band A against it. The rotating shaft 8 is rotated forward, and the adjusting pins B are pushed by the push-out shaft 10 into the extraction hole 11.

<Effects of the Invention> As described above, the present invention has the effect of providing a jig that can be easily used by anyone at a store or the like when extracting adjusting pins. Since the receiving member is prepared in several types with different curved surfaces and is replaceable, it is possible to prevent the pieces from opening and escape by attaching a matching member, and it can be applied to most watch bands. The effect is that it is possible to Since it is pushed out by rotating forward, it is possible to push out the adjusting pins without any difficulty. This effect occurs.
