 The above-mentioned problem is to provide a recessed portion on the rear side of the buckle, provide an opening at one end of the recessed portion, provide shaft holes on both side walls of the opening, provide a shaft rod in the shaft hole, and provide a groove hole at the center of the recessed portion. Each recessed hole is provided in both side walls of the groove, a shaft rod is provided in the recessed hole, a fitting wall is provided at each end of the opening of the recessed portion, a stop hole is provided in the fitting wall, and the front end of the joining piece is joined. A lump is provided in a convex shape, a joining groove is provided at the bottom end of the joining lump, a fitting piece is pivotally contacted in the opening of the recessed portion, a shaft seat is provided on one side of the fitting piece, and a shaft hole is provided in the shaft seat. Is provided, a fitting block is provided on the other side of the fitting piece, and a convex particle is provided inside the fitting block.

[0006]

[Action]

 With the above configuration, the joint groove of the front end joint mass of the joint piece is hung on the shaft rod in the groove on the rear side of the buckle to reach the pivotal connection, and the joint piece is sandwiched by the joint piece, and the wristband is attached. It acts stably after being pivoted so as not to fall off.

【Example】

 The technical means adopted by the present invention to attain the above-mentioned objects and effects will be described with reference to the drawings with reference to a comparatively preferable embodiment. First, referring to FIG. 1, the main part of the present invention is that a buckle 2, a pivot port 20 is provided on the front side of the buckle 2, and both side walls of the pivot port 20 have penetrating holes 200 penetrating outward. The buckle 2 is provided with a recess 21 on the rear side thereof, an opening 22 is provided on the right side of the recess 21, and shaft holes 220 are provided on both side walls of the opening 22. Further, the rear side wall shaft hole 220 is penetrated to the outside, a shaft rod 221 is provided in both shaft holes 220, a groove hole 23 is provided at the center of the concave portion 21, and concave holes 230 are provided on both side walls of the groove hole 23. Also, the recessed hole 230 on the left side wall of the slot 23 penetrates to the outside, and the shaft rod 231 is provided in the recessed hole 230. Further, a fitting wall 24 is provided on the left side of the concave portion 21, and a retaining hole 240 having a larger diameter is provided in the fitting wall 24 at a position of a penetrating concave hole 230 facing outward.

The joining piece 3 is fitted into the shaft bar 231 of the rear groove opening 23 of the buckle 2, the joining piece 30 is provided at the front end of the joining piece 3, and the mushroom-shaped joining groove 300 is formed at the bottom end of the joining piece 30. Further, a pivotal contact hole 31 is provided on the rear side of the joint piece 3, and a contact hole 310 penetrating outward is provided on both side walls of the pivotal contact hole 31. The joining piece 4 is pivotally connected to the shaft rod 221 of the right opening 22 of the buckle 2, and the fitting piece 4 is in the form of a thin plate, and its thickness is equal to the height at which the recess 21 of the buckle 2 is recessed. A shaft seat 40 is provided on one side of the fitting piece 4, and a shaft hole 400 is provided in the shaft seat 40. Further, a fitting lump 41 is provided on the other side of the fitting piece 4, and a convex grain 410 is provided inside the fitting lump 41.

At the time of assembly (see FIGS. 1 and 2), the shaft seat 40 of the fitting piece 4 is assembled into the opening 22 on the right side of the buckle 2, and the shaft rod 221 is further inserted into the shaft holes 220 and 400 to fix it. Set. Further, the convex piece A1 and the contact rod A10 of the wristwatch band A are pivotally connected to the contact hole 310 of the joint piece 3 on the rear pivot joint port 31 and the front hole 200 of the front pivot joint port 20 of the buckle 2. Thus, the assembly is completed.

When the wristwatch is worn on the wrist (see FIGS. 2 to 5), the joining groove 300 of the joining block 30 at the front end of the joining piece 3 is put on the shaft rod 231 in the rear groove opening 23 of the buckle 2. Next, the fitting block 41 of the fitting piece 4 is fitted to the fitting wall 24 on the left side of the buckle 2. At the same time, the convex grain 410 inside the fitting block 41 is hooked in the stop hole 240 of the fitting wall 24. The installation is completed in this way. Then, when the joining groove 300 of the joining piece 3 front end joining block 30 is hung on the horizontal bar 231 of the buckle 2 rear side groove opening 23, it can be firmly put. Further, the upper portion of the joining piece 3 receives the fitting piece 4 being held. Therefore, the joint piece 3 and the buckle 2 are extremely stable after being pivotally contacted with each other, and even if the joint piece 3 and the buckle 2 are pivotally contacted with each other, the wristwatch does not fall off or break even if it is moved due to shock or carelessness.

[0011]
