Description

Technical Field

[0001] This invention relates to the technical field of clothing accessories, and in particular to a button for clothing, jeans, work pants, bags and other items. Background Technology

[0002] Buttons used for clothing, jeans, work pants, bags, etc., typically consist of a button body and a fastener. The button body is positioned on the front of the item, and the fastener is a rivet structure that inserts into the button body from the back of the item and secures it to the button body. This clamps the fabric at that location between the button body and the fastener, thus fixing the button to the fabric at that location. For example, the button disclosed in Chinese invention patent application CN1671312B.

[0003] When recycling items equipped with the aforementioned buttons, the buttons need to be removed from the fabric so that the fabric can be recycled. However, the fasteners in the existing buttons are rivet structures, which are difficult to remove from the fabric once fixed to the button body, increasing the difficulty of recycling the items.

[0004] To address the aforementioned issues, Chinese invention patent application CN113491375B discloses a snap fastener with a detachable screw. The snap fastener has an internal cavity to accommodate the screw's post portion. The inner wall of the cavity has protrusions and recesses, while the outer surface of the screw's post portion is threaded. The protrusions and recesses on the inner wall of the snap fastener's cavity engage with the threads on the outer surface of the screw's post portion. Thus, after the screw's post portion is inserted into the snap fastener's cavity, rotating at least one of the snap fastener and screw allows them to be separated, enabling easy removal from the fabric for recycling. However, this snap fastener with a detachable screw requires machining protrusions and recesses on the inner wall of the snap fastener and threads on the outer surface of the screw's post portion, increasing the manufacturing difficulty and cost of the snap fastener and screw, and consequently increasing the overall cost of the button. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a button that is low-cost and easy to remove from clothing.

[0006] To achieve the above objectives, the present invention provides a button, comprising a button body and a fixing member. The button body has a fixing hole, and the fixing member includes an insertion shaft portion and a base portion fixed to the bottom of the insertion shaft portion. The insertion shaft portion is fixedly inserted into the fixing hole. The fixing member has a groove recessed into the button body on the bottom surface of the base portion. The base portion has a thinning portion axially opposite to the groove, and the thinning portion is distributed on the outer periphery of the insertion shaft portion.

[0007] The button of the present invention is fixedly inserted into the fixing hole of the button body by the insertion shaft of the fixing member, thereby realizing the fixed connection between the fixing member and the button body. At the same time, the fabric of the item is clamped between the base of the fixing member and the button body, thereby fixing the button as a whole to the fabric. Specifically, based on the groove provided on the fastener of this application, the base of the fastener has a thinned portion with reduced thickness. Therefore, the strength of the fastener is low at the thinned portion. When recycling the fabric of the item, after inserting a disassembly tool such as a knife into the groove and impacting the base of the fastener, the tip of the knife abuts against the bottom of the thinned portion. Since the strength of the fastener is low at the thinned portion, after the knife impacts the base at the bottom of the thinned portion, the base easily breaks at the thinned portion, thus easily separating the button into two parts. These two parts are: one part is the base portion distributed on the outer periphery of the break, and the other part is the button body, the insertion shaft fixed in the button body, and the base portion fixed on the outer periphery of the insertion shaft and distributed on the inner periphery of the break. Then, the part with the button body can be pulled out from the hole in the fabric.

[0008] Therefore, this application provides a groove and a thinning portion on the base of the fastener, making it easy for the base to break into two parts at the thinning portion, thereby facilitating the removal of the button from the fabric. Furthermore, the groove on the base is easy to process and has low cost, which helps to reduce the overall cost of the button. Ultimately, this application enables the removal of the button from the fabric in a low-cost and easy manner.

[0009] Furthermore, the thinned portion is located near the connection between the insertion shaft and the base, making it even closer to the insertion shaft. This arrangement has two advantages: First, when the base breaks at the groove and thinned portion during button removal, the breakage point is closer to the insertion shaft, making the bottom of the broken insertion shaft thinner. This prevents it from being too thick and getting stuck in the fabric when pulled out of the opening, making it easier and smoother to remove. Second, the fastener is connected to the base via a rounded section, providing better structural strength at this connection. The closer proximity of the groove and thinned portion to the rounded section satisfies the need to prevent damage to the base during button removal while also improving the structural strength of the fastener during normal use, preventing accidental breakage at the groove and thinned portion.

[0010] Furthermore, the grooves on the bottom surface of the chassis can be arranged in several ways: Preferred method one: the groove consists of several segments, spaced apart along the same circumferential direction, each segment being an arc shape. Preferred method two: the groove is a circular groove. Users can choose the specific arrangement of the grooves according to their actual needs.

[0011] Furthermore, along the radial direction of the insertion shaft, the apex of the groove is distributed on the outer periphery of the insertion shaft. This arrangement ensures that the apex of the groove (i.e., the highest point of the groove) does not extend inward beyond the outer periphery of the insertion shaft in the radial direction, thereby making it easier to achieve breakage at the thinned portion.

[0012] Furthermore, based on the limitation that the apex of the groove does not extend inward beyond the outer circumference of the insertion shaft, the cross-sectional shape of the groove can be varied, preferably triangular, trapezoidal, or elongated, and the user can choose according to actual needs.

[0013] Furthermore, along the radial direction of the insertion shaft, the distance from the apex of the groove to the central axis of the base is 1.1 to 1.7 times the radius of the insertion shaft, which better balances the strength requirements during normal use of the button and the requirement that the button is easily damaged when disassembled.

[0014] Furthermore, the groove has a triangular cross-sectional shape. More specifically, the groove wall includes an inner groove wall, an outer groove wall distributed on the outer periphery of the inner groove wall, and an arc-shaped transition groove wall connecting the tops of the inner and outer groove walls. The inner groove wall extends obliquely, moving further away from the arc-shaped transition groove wall and closer to the central axis of the chassis. The outer groove wall also extends obliquely, moving further away from the arc-shaped transition groove wall and further away from the central axis of the chassis. With this configuration, the obliquely arranged inner and outer groove walls form the inner and outer sides of a triangular cross-section. The arc-shaped transition groove wall is equivalent to the top edge formed by rounding the tip of the triangular groove. Furthermore, the oblique arrangement of the inner and outer groove walls minimizes the thickness of the chassis at the arc-shaped transition groove wall, meaning the thinned portion has the minimum thickness at the location directly opposite the arc-shaped transition groove wall. This makes it easier for the chassis to break at the arc-shaped transition groove wall when removing the button.

[0015] Furthermore, the inclination angle of the inner groove wall relative to the bottom surface of the chassis is greater than the inclination angle of the outer groove wall relative to the bottom surface of the chassis. This design allows the blade tip to better fit against the arc-shaped transition groove wall, ensuring the blade tip fits better at the thinnest part of the chassis, thus improving the reliability of button removal. Simultaneously, it ensures the blade tip has a suitable thickness, preventing damage due to excessive thinness and avoiding damage to the chassis due to excessive thickness, thus balancing the durability of the blade with the ease of button removal.

[0016] Furthermore, along the thickness direction of the base portion, the depth of the groove is 0.6 to 0.7 times the thickness of the base portion. This satisfies the requirement that the base portion is easily damaged during button removal due to the groove, while also preventing the base portion from accidentally breaking at the groove during normal use. This balances the strength requirements for normal use of the button and the requirement that the button is easily damaged during removal.

[0017] Furthermore, along the radial direction of the insertion shaft, the distance from the inner circumference of the groove to the central axis of the base portion is 1.1 to 1.2 times the radius of the insertion shaft, so that both the groove and the thinning portion are close to the insertion shaft, so that even if the button is damaged when it is removed from the fabric, it can be easily pulled out of the hole in the fabric without being stuck by the fabric, making the removal of the button easier and smoother.

[0018] Furthermore, the base portion is disc-shaped; along the radial direction of the insertion shaft portion, the width of the groove is 0.2 to 0.4 times the radius of the base portion, which better balances the strength requirements during normal use of the button and the requirement that the button is easily damaged when disassembled.

[0019] Furthermore, the fixing hole is a stepped hole, comprising several segments connected sequentially in a direction away from the base, with the hole diameter gradually increasing. This configuration allows for better engagement between the insertion shaft and the fixing hole, achieving better integration of the fastener and the button body after fixation. Simultaneously, when using a resin-molded receiving component, the stepped hole design within the receiving component ensures that the mandrel used to form the fixing hole in the molding die has a progressively thinning stepped shaft structure, preventing bending when removed from the molded product and facilitating demolding.

[0020] Furthermore, the outer periphery of the portion of the insertion shaft near the chassis is provided with several protruding sections. These protruding sections extend axially along the insertion shaft and are spaced apart circumferentially along the insertion shaft. The protruding sections are interference-fitted with the fixing hole, which increases the fastening force between the insertion shaft and the wall of the fixing hole, better realizing the integration of the fastener and the button body after the fastener and the button body are fixedly connected, and reliably avoiding the adverse phenomenon of relative rotation after the fastener and the button body are fixedly connected.

[0021] Furthermore, the button body includes a shell component constituting the button's outer casing and a receiving component fixed inside the shell component, with the fixing hole formed within the receiving component; the receiving component is made of a softer material than the shell component; preferably, the receiving component is made of resin, and the shell component is made of metal. After the insertion shaft of the fixing member is inserted into the receiving component, the insertion shaft can better engage with the receiving component, and the receiving component can better engage with the shell component. Simultaneously, the metal shell component provides the button with a better appearance and also makes the button more durable.

[0022] As described above, the button of the present invention has the following beneficial effects:

[0023] This application provides a groove and a thinning portion on the base of the fastener, making it easy for the base to break into two parts at the thinning portion, thereby facilitating the removal of the button from the fabric. Furthermore, the groove on the base is easy to machine and inexpensive, which helps to reduce the overall cost of the button. Ultimately, this application enables the removal of the button from the fabric in a low-cost and easy manner. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0074] This invention relates to a button that can be used on clothing, jeans, work pants, bags, and other items. Figure 2 and Figure 14 As shown, after the button is fixed to the fabric 110 of the item, the button has a front facing outwards and a back facing inwards. For ease of description, in the following embodiments, the end of the button with the front face is defined as the top end, and the end of the button with the back face is defined as the bottom end, and the direction from the bottom end to the top end of the button is the upward direction. Based on this, Figure 2 In the view shown, the top side of the paper is the upward direction, and the bottom side is the downward direction. Therefore, the front of the button is also the top surface of the button, and the back of the button is also the bottom surface of the button.

[0075] like Figure 1 and Figure 2 As shown, the button involved in this invention includes a button body 100 and a fastener 200; as Figures 3 to 5 As shown, the button body 100 has a vertically extending fixing hole 41. The lower end of the fixing hole 41 extends downward to the bottom of the button body 100, so the opening of the fixing hole 41 faces downward; Figures 6 to 8 As shown, the fastener 200 includes an insertion shaft portion 50 extending axially in the vertical direction and a base portion 60 fixed to the bottom of the insertion shaft portion 50. The base portion 60 is disc-shaped. The insertion shaft portion 50 is used to insert upward from the lower end of the fixing insertion hole 41 into the fixing insertion hole 41 until it is fixedly inserted into the fixing insertion hole 41, thereby fixing the fastener 200 in the button body 100. In particular, the fastener 200 has a groove 61 on the bottom surface of the base portion 60. The groove 61 is recessed upward in the direction of the button body 100. After the recessed groove 61 is provided on the base portion 60, the thickness of the base portion 60 at the groove 61 is reduced, thereby providing a thinning portion 62 on the base portion 60 that is axially opposite to the groove 61. That is, the part of the base portion 60 distributed above the groove 61 constitutes the thinning portion 62. The thinning portion 62 is distributed on the outer periphery of the insertion shaft portion 50.

[0076] When the button is not installed, the button body 100 and the fastener 200 are two separate parts. When installing the button on the fabric 110 of the item, place the button body 100 on the front side of the fabric 110 and the fastener 200 on the back side of the fabric 110, with the fabric 110 separating the button body 100 and the fastener 200; then, insert the insertion shaft 50 of the fastener 200 into the hole on the fabric 110 and the fixing insertion hole 41 of the button body 100, until the insertion shaft 50 is fully inserted into the fixing insertion hole 41. At this time, if... Figure 13 As shown, the insertion shaft 50 of the fastener 200 is fixedly inserted into the fixing hole 41 of the button body 100, realizing a fixed connection between the fastener 200 and the button body 100. Simultaneously, it clamps the fabric 110 between the base 60 of the fastener 200 and the button body 100, thereby fixing the button as a whole onto the fabric 110. Preferably, when installing the button, a button presser can be used to press the insertion shaft 50 of the fastener 200 into and fix it in the fixing hole 41 of the button body 100.

[0077] The recessed groove 61 on the bottom surface of the fastener 200 results in a thinned portion 62 on the upper side of the base portion 60 of the fastener 200, where the strength of the fastener 200 is lower at the thinned portion 62. Therefore, the base portion 60 of the fastener 200 is prone to breakage at the thinned portion 62 under external force. Based on this, when recycling the clothing fabric 110 and removing the buttons from the fabric 110 using tools such as a knife 70, if... Figure 14 As shown, the upper end of the cutter 70 is a cutting tip 71. The cutting tip 71 of the cutter 70 is inserted into the groove 61 on the bottom surface of the base portion 60. The cutting tip 71 of the cutter 70 abuts against the bottom of the thinning portion 62. The cutter 70 impacts the base portion 60 of the fixing member 200 upwards. Because the cutting tip 71 abuts against the thinning portion 62 after impacting the base portion 60 of the fixing member 200, and because the strength of the base portion 60 at the thinning portion 62 is relatively low, the base portion 60 easily breaks off at the thinning portion 62 after the cutter 70 impacts upwards at the bottom of the thinning portion 62. After the base portion 60 breaks off, as... Figure 15 As shown, the button is split into two parts, defined as the first part 81 and the second part 82. The first part 81 is a portion of the base 60 distributed on the outer periphery of the break. The first part 81 is annular and separable from the fabric 110 after breakage. The second part 82 consists of the button body 100, the insertion shaft 50 fixed in the button body 100, and the portion of the base 60 fixed on the outer periphery of the insertion shaft 50 and distributed on the inner periphery of the break. Finally, the first part 81 is removed, and the second part 82, which contains the button body 100, is pulled upward from the hole in the fabric 110, thereby removing the button from the fabric 110. The fabric 110 can then be recycled.

[0078] Therefore, by providing a groove 61 and a thinning portion 62 on the base portion 60 of the fastener 200, the base portion 60 can be easily broken into two parts at the thinning portion 62, thereby facilitating the removal of the button from the fabric 110. Furthermore, machining the groove 61 on the base portion 60 is also easy and cost-effective, thus reducing the overall cost of the button. Ultimately, this application achieves low-cost and easy removal of the button from the fabric 110.

[0079] Furthermore, such as Figures 3 to 5 As shown, the button body 100 includes a shell component 30 constituting the button's outer shell and a receiving component 40 fixed inside the shell component 30. A fixing hole 41 is formed inside the receiving component 40 and passes through the receiving component 40 in the vertical direction. The shell component 30 includes a shell cover portion 31 and a shell base portion 32 fixed to each other. Both the shell cover portion 31 and the shell base portion 32 are formed by metal deep drawing. Therefore, the material of the shell component 30 is metal. The metal shell component 30 gives the button a better appearance and also makes the button more durable. The receiving component 40 includes a vertically extending columnar base 42 and a flange portion 43 extending radially outward from the top of the columnar base 42, the flange portion 43 being disc-shaped. A housing cover portion 31 is encapsulated on the top of the flange portion 43, and this housing cover portion 31 is also disc-shaped, thus blocking the upper opening of the fixing hole 41. Simultaneously, the housing base portion 32 is encapsulated on the bottom and outer periphery of the flange portion 43, and the fixing connection points of the housing cover portion 31 and the housing base portion 32 are distributed on the outer periphery of the flange portion 43. A portion of the lower end of the columnar base 42 extends downward from the lower end of the housing base portion 32. Furthermore, in other embodiments, the receiving component 40 may only include the columnar base 42.

[0080] Furthermore, the specific shape of the columnar substrate 42 is not particularly limited, and the columnar substrate 42 can have various shapes. In this embodiment, preferably, such as Figure 5 As shown, the housing component 40 has a fixed step portion 44 on the outer periphery of its columnar base 42, and the lower end of the housing base portion 32 bends inward at the fixed step portion 44, thereby forming an engagement portion 321 that bites into the columnar base 42, thereby improving the fixation reliability between the housing base portion 32 and the housing component 40.

[0081] Furthermore, the housing component 40 is made of a softer material than the housing component 30; for example, the housing component 40 is made by resin injection molding, which facilitates the manufacturing of the housing component 40. Additionally, such as... Figure 5 As shown, the fixed socket 41 is a stepped hole, and the fixed socket 41 includes several socket segments 411 that are connected sequentially from bottom to top in a direction away from the chassis portion 60 and whose diameter gradually increases. Figure 5In the view shown, the fixing hole 41 has three segments 411, with the lowest segment having the smallest diameter and the highest segment having the largest diameter. With this arrangement, when the insertion shaft 50 of the fastener 200 is inserted upwards into the fixing hole 41 of the receiving member 40, the expansion of the receiving member 40 gradually increases as the insertion shaft 50 is inserted, thus gradually increasing the engagement between the receiving member 40 and the housing member 30. This makes the receiving member 40 and the housing member 30 more reliably fixed together, ensuring the integrated fixation of the receiving member 40 and the housing member 30. Simultaneously, it reliably ensures the engagement between the insertion shaft 50 and the fixing hole 41, better achieving the integrated fixation of the fastener 200 and the button body 100. Therefore, after the fastener 200 and the button body 100 are fixed together by the engagement of the insertion shaft 50 and the fixing hole 41, the insertion shaft 50 and the receiving component 40, as well as the receiving component 40 and the housing component 30, can be well engaged and fixed, ensuring the integration of the button and the reliability of the button's fixation on the fabric 110, preventing the fastener 200 from accidentally detaching from the button body 100 during use. Furthermore, based on the resin injection molding of the receiving component 40 and the stepped hole structure of the fixing hole 41 within the receiving component 40, the mandrel used to form the fixing hole 41 in the molding die has a progressively thinning stepped shaft structure, which will not bend when removed from the molded product, making demolding easier.

[0082] Preferably, such as Figures 6 to 8 As shown, the fastener 200 is a one-piece molded part made of metal, which enhances its structural strength and durability, thus increasing the lifespan of the button. Furthermore, the metal fastener 200 and the metal housing component 30 provide a unified metallic appearance for the button fixed to the fabric 110, enhancing the overall quality of the item.

[0083] Furthermore, the groove 61 on the bottom surface of the chassis 60 can be arranged in several ways: Preferred method one: the groove 61 has several segments, which are spaced apart along the same circumferential direction, and each segment is arc-shaped. Preferred method two: the groove 61 is a circular groove. The user can choose the specific arrangement of the groove 61 according to actual needs.

[0084] Furthermore, such as Figure 8As shown, along the radial direction of the insertion shaft portion 50, the apex of the groove 61 is distributed on the outer periphery of the insertion shaft portion 50; specifically, a parallel line S parallel to the central axis of the insertion shaft portion 50 is drawn from the apex (i.e., the highest point) of the groove 61. This parallel line S is distributed around the entire periphery of the insertion shaft portion 50 (including the convex portion 51 described below) without extending inward beyond the outer periphery of the insertion shaft portion 50 (including the convex portion 51 described below). With this arrangement, the apex of the groove 61 is slightly away from the insertion shaft portion 50 in the radial direction, thereby making it easier to achieve breakage at the thinned portion 62. Preferably, along the radial direction of the insertion shaft portion 50, the distance M from the apex of the groove 61 (i.e., the highest point of the arc transition groove wall 613 described below) to the central axis of the base portion 60 is greater than the radius R1 of the insertion shaft portion 50. Specifically, the distance M from the apex of the groove 61 to the central axis of the base portion 60 is 1.1 to 1.7 times the radius R1 of the insertion shaft portion 50, so that the apex of the groove 61 is close to the outer peripheral surface of the insertion shaft portion 50, but does not extend inward beyond the outer peripheral surface of the insertion shaft portion 50, thereby better balancing the strength requirements during normal use of the button and the requirement that the button is easily damaged during disassembly.

[0085] Furthermore, based on the structural arrangement that the apex of the groove 61 does not extend inward beyond the insertion shaft portion 50, the cross-sectional shape of the groove 61 can be varied, or in other words, it can be any shape. The preferred cross-sectional shape of the groove 61 is: Figure 8 The triangle shown may be Figure 10 The right triangle shown is, or is Figure 11 The elongated shape shown may be Figure 12 The trapezoid shown can be selected by the user according to actual needs. In this embodiment, as... Figure 6 As shown, groove 61 is a circular groove; as Figure 8 As shown, the cross-sectional shape of the groove 61 is triangular. In other embodiments, the cross-sectional shape of the groove 61 may also be an irregular quadrilateral or a trapezoid with asymmetrical left and right sides.

[0086] Furthermore, such as Figures 6 to 8As shown, the thinned portion 62 is close to the connection between the insertion shaft portion 50 and the base portion 60. Preferably, along the radial direction of the insertion shaft portion 50, the distance L from the inner circumference of the groove 61 to the central axis of the base portion 60 is 1.1 to 1.2 times the radius R1 of the insertion shaft portion 50, so that the groove 61 and the thinned portion 62 are closer to the insertion shaft portion 50. With this arrangement, on the one hand, when the button is removed, after the base portion 60 breaks at the groove 61 and the thinned portion 62, the breakage position is closer to the insertion shaft portion 50, so that less base portion 60 remains at the bottom of the second part 82 after breakage. That is, the bottom part of the insertion shaft portion 50 in the second part 82 is thinner, which prevents it from being stuck in the fabric 110 due to being too thick when it is pulled out of the hole of the fabric 110, making it easier and smoother to remove from the fabric 110. On the other hand, the fastener 200 is connected to the insertion shaft portion 50 and the base portion 60 by a transitional arc portion 90. Thus, the fastener 200 has good structural strength at the connection between the insertion shaft portion 50 and the base portion 60. The groove 61 and the thinning portion 62 are set closer to the insertion shaft portion 50, and thus closer to the arc portion 90. This avoids the base portion 60, which has a relatively small thickness, from having a very thin section due to the groove 61. This satisfies the requirement that the base portion 60 is easily damaged when the button is removed, and also improves the structural strength of the fastener 200 during normal use, preventing the button from accidentally breaking at the groove 61 and the thinning portion 62 during normal use.

[0087] Furthermore, such as Figure 8 As shown, along the thickness direction of the base portion 60, the depth H of the groove 61 is 0.6 to 0.7 times the thickness D of the base portion 60. This satisfies the requirement that the base portion 60 is easily damaged during button removal due to the groove 61, while also preventing the base portion 60 from accidentally breaking at the groove 61 during normal use. This balances the strength requirements for normal use and the need to prevent damage during button removal. Simultaneously, along the radial direction of the insertion shaft portion 50, the width W of the groove 61 is 0.2 to 0.4 times the radius R2 of the base portion 60, further balancing the strength requirements for normal use and the need to prevent damage during button removal.

[0088] Furthermore, the preferred structure of the triangular cross-section groove 61 is as follows: Figure 8 and Figure 9As shown, the groove wall of the groove 61 includes an inner groove wall 611, an outer groove wall 612 distributed on the outer periphery of the inner groove wall 611, and an arc transition groove wall 613 connecting the top ends of the inner groove wall 611 and the outer groove wall 612. The inner groove wall 611 extends obliquely towards the central axis of the chassis 60 as it moves further away from the arc transition groove wall 613. The outer groove wall 612 extends obliquely towards the central axis of the chassis 60 as it moves further away from the arc transition groove wall 613. That is, the lower end of the inner groove wall 611 extends obliquely inward and downward, and the lower end of the outer groove wall 612 extends obliquely outward and downward. The oblique directions of the inner groove wall 611 and the outer groove wall 612 are opposite. With this arrangement, the obliquely arranged inner groove wall 611 and outer groove wall 612 in the groove wall of the groove 61 form the inner and outer sides of a triangular cross-section. The arc transition groove wall 613 is equivalent to the top edge formed by rounding the top tip of the triangular cross-section groove 61. The inclination of the inner groove wall 611 and the outer groove wall 612 of the groove 61 minimizes the thickness of the chassis portion 60 at the arc transition groove wall 613. This also means that the thinned portion 62 has the minimum thickness at the part directly opposite the arc transition groove wall 613, making it easier for the chassis portion 60 to break at the arc transition groove wall 613 when removing the button.

[0089] Preferably, such as Figure 9 As shown, the inclination angle β of the inner groove wall 611 relative to the bottom surface of the chassis portion 60 is greater than the inclination angle α of the outer groove wall 612 relative to the bottom surface of the chassis portion 60. In this embodiment, the inclination angle β of the inner groove wall 611 relative to the bottom surface of the chassis portion 60 is 65° to 75°, preferably 70°, and the inclination angle α of the outer groove wall 612 relative to the bottom surface of the chassis portion 60 is 30° to 40°, preferably 32°. When disassembling the button, as... Figure 14 As shown, the tip 71 of the cutter 70 abuts against the arc transition groove wall 613, and the outer peripheral surface of the top of the cutter 70 is attached to or adjacent to the outer groove wall 612. Because the inclination angle α of the outer groove wall 612 relative to the bottom surface of the base 60 is small, and the inclination direction of the inner groove wall 611 is opposite to that of the outer groove wall 612, the tip 71 of the cutter 70 can better fit against the arc transition groove wall 613, meaning the tip 71 of the cutter 70 can better fit against the thinnest part of the base 60, improving the reliability of the button removal. Simultaneously, the tip 71 of the cutter 70 can be of suitable thickness, preventing it from being too thin and thus missing or damaged, or too thick and thus preventing the base 60 from being difficult to break, thus balancing the durability of the cutter 70 with the operability of button removal.

[0090] Preferably, such as Figure 14As shown, the cutter 70 has an internal clearance groove 72. The upper end of the clearance groove 72 extends upward to the top surface of the cutter 70, and the upper opening of the clearance groove 72 faces the base portion 60. The size of the opening of the clearance groove 72 should be sufficient to accommodate the portion of the base portion 60 on the inner periphery of the groove 61, and allow the cutter tip 71 to abut against the arc transition groove wall 613 of the groove 61.

[0091] Furthermore, such as Figure 6 and Figure 7 As shown, a number of protruding sections 51 are fixedly provided on the outer periphery of the portion of the insertion shaft 50 near the chassis 60. The protruding sections 51 extend along the axial direction of the insertion shaft 50 and are distributed at intervals along the circumferential direction of the insertion shaft 50. The protruding sections 51 are interference-fitted with the fixing hole 41, which increases the fastening force between the insertion shaft 50 and the hole wall of the fixing hole 41, and better realizes the integration of the fastener 200 and the button body 100 after being fixedly connected, and reliably avoids the adverse phenomenon of relative rotation after the fastener 200 and the button body 100 are fixedly connected.

[0092] Furthermore, such as Figure 4 As shown, the bottom surface of the receiving component 40 is provided with several downward-protruding limiting protrusions 45 that are circumferentially spaced, such as... Figure 6 As shown, the top surface of the chassis portion 60 is provided with an annular recess 63 and several limiting protrusions 64 distributed on the inner periphery of the annular recess 63. After the button is fixed to the fabric 110, the limiting protrusions 45 and 64 are arranged opposite each other across the fabric 110 to prevent the button body 100 and the fastener 200 from rotating relative to the fabric 110.

[0093] Furthermore, such as Figure 6 and Figure 7 As shown, the fixing member 200 has a conical insertion guide 52 at the top of the insertion shaft portion 50. The pointed end of the insertion guide 52 facilitates the insertion of the insertion shaft portion 50 into the fixing hole 41. At the same time, the outer diameter of the lower end of the insertion guide 52 is larger than the outer diameter of the insertion shaft portion 50, thereby forming a locking portion 53 at the lower end of the insertion guide 52, which allows the insertion shaft portion 50 to better engage with the receiving member 40.
