[0026] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0027] Please refer to Figure 1 and Figure 2 The watchband disassembly and assembly device 100 provided in the embodiment of the utility model comprises a main body 1 and an ejector assembly 3 , and the ejector assembly 3 is installed to the main body 1 .

[0028] Among them, the main body 1 is provided with a strap placement groove 11; the ejector assembly 3 includes an ejector 31 and an ejector seat 32; and the ejector 31 is arranged on the ejector seat 32. Specifically, the ejector 31 is fixed to the ejector seat 32; or the ejector 31 and the ejector seat 32 form an integrated assembly. The ejector seat 32 can move relative to the main body 1, so that the ejector 31 can be inserted into the strap placement groove 11. For example, the main body 1 is provided with a channel for the ejector seat 32 to slide, and the channel is provided with a through hole for the ejector 31 to extend into the strap placement groove 11. It can be understood that the end face shape of the free end of the ejector 31 is adapted to the shape of the contact end of the ear or the pin of the strap to be removed, so that the ejector 31 can better contact the ear or the pin of the strap to be removed. For example: if the contact end of the ear or the pin of the strap to be removed is a convex surface, then the end face of the free end of the ejector 31 is a concave surface.

[0029] Preferably, the main body 1 is provided with a positioning structure 15 corresponding to the position where the ejector pin 31 extends into the strap placement slot 11; the positioning structure 15 is provided by marking the parallel position and / or vertical position of the ejector pin 31 corresponding to the outer surface of the main body 1, so as to align the lug of the strap to be disassembled with the ejector pin 31. In this embodiment, the positioning structure 15 is in the shape of a groove; in an alternative embodiment, the positioning structure 15 is in the shape of a convex dot, a convex line, or a silk-screen / spray-painted marker without obvious concave-convex changes. In this embodiment, a reset spring is sleeved on the outer surface of the ejector pin 31, and the reset spring applies a reset force to the ejector pin seat 32 in a direction away from the strap placement slot 11. In this way, when the user lets go, the ejector pin 31 can reset itself. Furthermore, the ejector pin seat 32 is also provided with a stopper, which is used to prevent the ejector pin seat 32 from falling off from the main body 1; to ensure that the ejector pin 31 can reset itself through the reset spring.

[0030] Please refer to Figure 2 The strap disassembly and assembly device 100 also includes a thimble stroke adjustment assembly 5 for adjusting the depth of the thimble 31 extending into the strap placement slot 11. The thimble stroke adjustment assembly 5 is installed to the main body 1. The thimble stroke adjustment assembly 5 includes a limit member 51; the limit member 51 can move between a first position and a second position relative to the main body 1, and can be selectively stabilized in the first position or the second position. The limit member 51 limits the stroke of the thimble seat 32 in one of the first position and the second position, so that the thimble 31 extends into the strap placement slot 11 at different depths or different strokes when the limit member 51 is respectively located in the first position and the second position, so as to adapt to different types of straps.

[0031] The ejector stroke adjustment assembly 5 further includes an adjustment bracket 52 ; the adjustment bracket 52 is provided with a first slide groove 521 , and the limiter 51 slides in the first slide groove 521 ; and the limiter 51 can selectively slide to the first position or the second position.

[0032] Please refer to Figures 3 to 7Preferably, the adjustment bracket 52 is further provided with a second slide groove 522, and the second slide groove 522 is provided with a first positioning recess 5221 and a second positioning recess 5222; the stopper 51 is provided with a positioning protrusion 511. Please refer to Figure 7 , while the stopper 51 slides in the first slide groove 521, the stopper 51 slides in the second slide groove 522, and the positioning protrusion 511 can be selectively stabilized in the first positioning recess 5221 or the second positioning recess 5222. In this embodiment, please refer to Figure 3 and Figure 4 When the positioning protrusion 511 is stabilized in the first positioning recess 5221, the limiting member 51 is stabilized in the first position; at this time, the limiting member 51 does not limit the stroke of the ejector seat 32, so that the ejector 31 extends into the strap placement groove 11 to the deepest depth or the longest stroke. Please refer to Figure 5 and Figure 6 When the positioning protrusion 511 is stabilized in the second positioning recess 5222, the limiting member 51 is stabilized in the second position; at this time, the limiting member 51 limits the stroke of the ejector seat 32, so that the depth of the ejector 31 extending into the strap placement groove 11 becomes smaller or the stroke becomes shorter.

[0033] It is understandable that more positioning recesses can be provided. For example, the second slide groove 522 is also provided with a third positioning recess, and the positioning protrusion 511 can be selectively stabilized in the first positioning recess 5221, the second positioning recess 5222 and the third positioning recess. When the positioning protrusion 511 is respectively stabilized in the first positioning recess 5221, the second positioning recess 5222 and the third positioning recess, the limiter 51 is respectively stabilized in the first position, the second position and the third position, and the stroke of the ejector seat 32 is limited in at least two of the positions, so that the ejector 31 extends into the strap placement groove 11 at different depths when the limiter 51 is respectively located in the first position, the second position and the third position, so that more types of straps or more types of linking ears can be adapted. For example, when the limit member 51 is stable in the first position, the limit member 51 does not limit the stroke of the ejector seat 32, so that the ejector 31 extends into the strap placement groove 11 to the maximum depth; when the limit member 51 is stable in the second position or the third position, the limit member 51 limits the stroke of the ejector seat 32.

[0034] Please refer to Figure 2 and Figure 8 In this embodiment, the main body 1 includes a first cover 12 and a second cover 13 covering the first cover 12. The strap placement groove 11 is formed on the outer surface of the first cover 12; the limiter 51 and the adjustment bracket 52 are installed in the first cover 12, and the adjustment bracket 52 is located between the first cover 12 and the second cover 13. In this way, the ejector stroke adjustment assembly 5 is more convenient to assemble to the first cover 12; at the same time, the second cover 13 shields the internal structure of the strap disassembly and assembly device 100, making the overall product simple and beautiful.

[0035] Preferably, the second cover 13 is provided with a third slide groove 131, and the stopper 51 is provided with a protrusion 515, which serves as a switch for toggling the stopper 51 and can slide in the third slide groove 131. When the protrusion 515 slides in the third slide groove 131, the stopper 51 slides in the first slide groove 521 and the second slide groove 522 at the same time. The third slide groove 131 is provided with a third position and a fourth position. Accordingly, when the protrusion 515 slides to the third position of the third slide groove 131, the positioning protrusion 511 of the stopper 51 is stabilized in the first positioning recess 5221 of the second slide groove 522, and the stopper 51 is stabilized in the first position of the main body 1; when the protrusion 515 slides to the fourth position of the third slide groove 131, the positioning protrusion 511 of the stopper 51 is stabilized in the second positioning recess 5222 of the second slide groove 522, and the stopper 51 is stabilized in the second position of the main body 1. In this way, by adjusting the protrusion 515 of the limiting member 51 to be located at the third position or the fourth position of the third sliding groove 131 , the stroke length of the current ejector pin 31 extending into the strap placement groove 11 can be adjusted.

[0036] In a specific embodiment, both sides of the strap placement slot 11 are provided with ejector assemblies 3 and corresponding ejector stroke adjustment assemblies 5. The ejector seats 32 and ejector 31 on both sides are movable relative to the main body 1. Preferably, the limit members 51 on both sides symmetrically limit or do not limit the stroke of the ejector seat 32, so that the ejector 31 on both sides extend into the ear heads at both ends of the raw ears of the strap to be disassembled to the same depth.

[0037] Fig. 9 The diagram shows the use status of the watch band disassembling and assembling device 100 for disassembling and assembling a watch band 200A to be disassembled and assembling having a raw ear for connecting a watch bead. Fig.10 Shows Fig. 9 The convex-concave watch grain 201A and the first linking lug 202A of the watch band 200A to be disassembled have an upper convex portion and a lower concave portion. Of the two adjacent convex-concave watch grains 201A, the upper convex portion of one convex-concave watch grain 201A extends into the lower concave portion of the other convex-concave watch grain 201A, the first linking lug 202A crosses the upper convex portion, and the two ends of the first linking lug 202A are respectively inserted into the two sides of the lower concave portion, thereby connecting the two convex-concave watch grains 201A in series.

[0038] Please refer to Fig. 9 and Fig.10, the through tube in the middle of the first link ear 202A is shorter, so the telescopic stroke of the ear heads at both ends is longer. When disassembling the watch strap, it is necessary to compress the ear heads at both ends of the first link ear 202A to the two sides of the upper convex part of the convex-concave watch grain 201A, so that the two adjacent convex-concave watch grains 201A can be separated from each other. In this way, the ejector pin adapted to the first link ear 202A needs to extend a deeper distance into the watch strap placement groove 11. In this embodiment, it can be corresponded to the aforementioned first position. In this state, the limit member 51 does not limit the stroke of the ejector pin seat 32, and the maximum stroke of the ejector pin 32 is limited by the cooperation between the main body and the ejector pin seat 31.

[0039] Fig.11 The diagram shows the use status of the watch band disassembling and assembling device 100 for disassembling and assembling another watch band 200B to be disassembled and assembling having a raw ear for connecting a watch bead. Fig.12 Shows Fig.11 The combined watch grain 201B and the second linking lug 202B of the watch band 200B to be disassembled are shown. The combined watch grain 201B includes a rectangular watch grain and a first side grain and a second side grain arranged on both sides of the rectangular watch grain. The middle through-tube of the second linking lug 202B is longer than the aforementioned first linking lug 202A, so the telescopic stroke of the lug heads at both ends is shorter. When disassembling the watch band, the lug heads at both ends of the second linking lug 202B are compressed to both sides of the combined watch grain 201B so that the combined watch grain 201B can be separated from the first side grain and the second side grain. In this embodiment, it can correspond to the aforementioned second position. In this state, the limit member 51 limits the stroke of the ejector seat 32 so that the maximum formation of the ejector 32 corresponds to the size of the second linking lug 202B.

[0040] Preferably, please refer to Fig. 9 and Fig.11 The width of the strap placement slot 11 varies, and at least one side end is provided with an escape position 111, so that the disassembled strap has an escape space. This design is also for the convenience of installing the strap.

[0041] Understandably, a third position, a fourth position, etc. may also be set, and the ejector pin 31 may have more strokes to adapt to more types of watch straps.

[0042] Furthermore, the main body 1 is also provided with a magnetic part, which is used to absorb the strap accessories such as the lugs or pins removed from the strap to avoid the loss of the accessories.

[0043] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
