Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a jig for adjusting and removing a watch band.

<Problems to be solved by this invention> This type of jig is disclosed in Japanese Utility Model Application Publication No. 164912/1983, which was previously proposed by the applicant. Because it stops, it cannot be used universally as a jig for adjusting and removing various watch bands, and there is also the problem that if the bit loses its shape due to repeated use, it becomes unusable. The present invention attempts to solve these problems.

<Structure of the invention> The invention has a fixed part and a sliding part that are arranged opposite to each other with a spring-wound shaft in between, and two sets of bits are replaceably arranged inwardly and oppositely on the inner surfaces of both sides of both parts,
The jig for adjusting and removing a watch band is further characterized in that a different type of bit and an extraction hole are provided in the middle, and a hole for inserting a spare bit is provided on one of the parts.

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

FIG. 1 is a plan view of the jig of the present invention, in which a fixed part 2a and a sliding part 2b each having a rectangular prism shape are disposed opposite to each other with two spring-wound shafts 1a and 1b interposed therebetween.
The slide part 2b is elastically slid in the direction of the fixed part 2a.

The inner surfaces on both sides of both parts 2a, 2b are separated, and adjusting bits 3a, 3b, 4a,
4b are arranged facing inward, respectively. Each bit is fitted with six screws, as shown in the example of bit 3b in FIG. 2, so that it can be replaced if it becomes deformed due to repeated use. Also fixed part 2a
As shown in FIG. 3, a removal bit 5 is attached to the inner surface of the middle part of the slide part 2b with a screw 6, and a hole 7 is provided in the opposite part of the slide part 2b. Furthermore, there is a hole 8 on the top surface of the slide part 2b for insertion.
is provided so that a spare removal bit 9 can be inserted.

Figure 4 shows the tip shape of each bit. Bits 3a and 3b are used when installing a straight pin type, bits 4a and 4b are used when installing a stepped pin type, and bits 5 and 9 are used when installing a stepped pin type. It is used for extracting type pins.

Generally, the jig 10 of the present invention is held with the thumb and fingers of one hand holding the fixed part 2a and the slide part 2b between them, and the jig 10 of the present invention is adjusted by pushing the slide part 2b toward the fixed part 2a. and removal. Figure 6 a, b,
c, d, e, f indicate the order in which the watch band pieces 11a, 11b are connected using bits 3a, 3b. First, insert the fixing pipe (C ring) 13 into the connecting hole 12 of the convex part of the piece 11a, and
After engaging the fixing pin (straight pin) 14, hold the jig 10 of the present invention and press the bit 3a.
As the pin 14 moves forward, the pin 14 is pushed in, and the tip is received by the bit 3b to stop the pin 14 in a predetermined position, thereby connecting the pieces with adjustment.
Figure 7 a, b, c, d, e are the meshed pieces 11a,
After inserting the stepped pin 15 into the connecting hole 12 of the bit 11b and moving the fixing pipe (C ring) 13 that was press-fitted to the tip of the bit 4b to the tip of the stepped pin 15,
Stepped pin 15 that can be pressed in place of bit 4a
An example of connection is shown.

FIGS. 8a, b, and c show examples of connections using hairpins 16, in which the pieces 11a and 11b are engaged and the connecting holes 1
2, push the hairpin 16 in from the direction without the split, hold the band 17 with both hands, and press the split side of the hairpin vertically against a flat surface (such as a pedestal).
It is pushed into the connecting hole 12.

To remove the pieces 11a and 11b, use the fixed part 2.
The bit 5 and the punch hole 7 or the spare removal bit 9 inserted into the inner surface of the middle part of the part a are used. When using the former, that is, using the bit 5 and punch hole 7, hold the jig 10 with one hand and the watch band 17 with the other hand, as shown in FIGS. 9a, b, and c. The bit 5 is inserted and then the slide part 2b of the jig 10 is pulled. The pin 14 is moved in the direction of the punch hole 7 and removed by pushing the bit 5. Stepped pin 1
5 can be removed in the same way. When using the latter, that is, the spare bit 9, as shown in the example of a hairpin in FIG.
The watch band 17 is lowered onto the slide part 2b. The hairpin can be pulled out upwards.

<Effects of the invention> As described above, the present invention can quickly connect and disconnect pieces using fixed pipes (C-rings) and straight pins, stepped pins, and hairpins. This has the effect of providing a jig that can be advanced. In addition, each bit is replaceable, so if the tip loses its shape, it can be replaced for continued use.
