Description

Position variable clock band fastening device by eccentric rotation {Clock Band clamping apparatus}

The present invention is disclosed with respect to the technical idea of a fastening device that promotes the bonding of bands to both sides of the case, and more specifically, when connecting the bands to both ends of the case, the width of the bonding pins is more easily and precisely controlled to maximize work efficiency. In addition to inducing the operation, the small-sized coupling pins can be handled easily and conveniently without any additional troubles, so it significantly improves the occurrence rate of errors or defects in the band fastening operation, ensuring overall ease of handling, use, maintenance and maintenance. It relates to a watch band fastening device.

In general, a watch worn on a wrist is divided into a case in which various information including time is displayed and a band that is tightened and constrained by the wearer's wrist, and the band is integrated at both ends of the case through a coupling pin having a predetermined structure.

As is well known, it is common for wrist watch bands to be formed of various materials such as metal, leather, synthetic resin, etc., and connected to the case by a coupling pin.

To explain this in more detail, insertion grooves are formed between the left and right extension protrusions with shaft holes on both sides of the case, and the spring pin is inserted in the width direction at the tip of the left and right bands, and inserted into the shaft holes of the left and right extension protrusions. Take the rescue

That is, if one side of the spring pin inserted at the tip of the band is inserted from the left and right extension protrusions of the case into the shaft hole of the one extension protrusion, the tip of the spring pin is removed when the external force pressing the tip of the spring pin is removed after positioning the tip of the spring pin. As the elastic protrusion is inserted into the shaft hole of the other extension protrusion, the shaft can be coupled.

As described above, in the conventional band, it is extremely difficult to insert the spring pin into the shaft hole formed in the left and right extension protrusions on both sides of the case, and there is an inconvenient problem that separate tools are required to smoothly insert the spring pin.

As a result, in the conventional band, the work of separating the spring pin at the tip of the band from the shaft hole of the left and right extension parts again for replacement of the band has been performed by hand, which increases the difficulty of the process and, of course, increases work efficiency. It is remarkably lowered, resulting in a fatal disruption in which productivity is also extremely poor.
