However, in the button with a detachable screw, concaves and convexes need to be processed on the inner wall of the button, and threads need to be processed on the outer surface of the screw column part, increasing the processing difficulty and cost of the button and the screw, and increasing the overall cost of the button. UTILITY MODEL CONTENTS

[0005] In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a button which is low in cost and easy to remove from the clothing material.

[0006] To achieve the above purpose, the utility model provides a button, which comprises a button body and a fixing part, a fixing socket is arranged in the button body, the fixing part comprises an insertion shaft part and a bottom disc part fixed at the bottom of the insertion shaft part, the insertion shaft part is fixedly inserted into the fixing socket, a groove recessed towards the button body is formed on the bottom surface of the bottom disc part, a thinned part axially opposite to the groove is arranged on the bottom disc part, and the thinned part is distributed on the outer circumferential side of the insertion shaft part.

[0007] The utility model relates to the button, through the fixed part's insertion shaft department fixedly inserted in the fixed button body's fixed jack, realize the fixed connection between fixed part and button body, still clamp the clothing of article between the bottom disc department of fixed part and button body to fixedly, thereby the button whole fixed on the clothing. Especially, based on the setting of the groove on the fixed part of the application, the bottom disc department of the fixed part has a thinning part with reduced thickness, so the strength of the fixed part at the thinning part is lower. After the cutting tool is inserted into the groove and impacts the bottom disc department of the fixed part using a cutting tool and other disassembly tools during the recycling process of the clothing of the article, the cutting tool tip abuts the bottom of the thinning part. Since the strength of the fixed part at the thinning part is lower, the bottom disc department is easily broken at the thinning part after the cutting tool impacts the bottom disc department at the bottom of the thinning part, and the button is easily disassembled into two parts. The two parts are: one part is the partial bottom disc department distributed on the outer peripheral side of the broken part, and the other part is the button body, the insertion shaft department fixed in the button body, and the partial bottom disc department fixed on the outer periphery of the insertion shaft department and distributed on the inner peripheral side of the broken part. Then, this part with the button body is extracted from the hole position of the clothing.

[0008] Therefore, the application easily breaks the bottom disc department into two parts at the thinning part by setting the groove and the thinning part on the bottom disc department of the fixed part, thereby easily realizing the disassembly of the button from the clothing. The application also easily realizes the machining of the groove on the bottom disc department, which is low in cost and helps to reduce the overall cost of the button. Finally, the application realizes the disassembly of the button from the clothing at low cost and easily.

[0009] Further, the thinning part is adjacent to the connection part of the insertion shaft department and the bottom disc department, so that the thinning part is closer to the insertion shaft department. After the bottom disc department is broken at the groove and the thinning part during the disassembly of the button, the broken position is closer to the insertion shaft department, the part of the bottom of the insertion shaft department after breaking is thinner, the clothing is not easily stuck when the part is extracted from the hole position of the clothing, and the part is easily and smoothly taken off from the clothing. On the other hand, the fixed part is connected through the arc part at the connection part of the insertion shaft department and the bottom disc department, so the fixed part has good structural strength at the connection part of the insertion shaft department and the bottom disc department. After the groove and the thinning part are set closer to the arc part, the bottom disc department is easily broken during the disassembly of the button, the structural strength of the fixed part during normal use of the button is improved, and the button is not accidentally broken at the groove and the thinning part during normal use.

[0010] Further, the groove on the bottom surface of the bottom disc department can have various setting modes: preferred mode one, the groove has several sections, and the several sections of the groove are distributed along the same circumferential direction, and each section of the groove is arc-shaped. Preferred mode two, the groove is a circular groove. The specific setting of the groove can be selected by the user according to the actual needs.

[0011] Further, the vertexes of the grooves are distributed on the outer circumferential side of the insertion shaft portion in the radial direction of the insertion shaft portion. In this way, the vertexes of the grooves do not protrude inward beyond the outer circumferential surface of the insertion shaft portion in the radial direction of the insertion shaft portion (i.e., the highest points of the grooves), so that the breaking at the thinning portion can be achieved more simply.

[0012] Further, based on the limitation that the vertexes of the grooves do not protrude inward beyond the outer circumferential surface of the insertion shaft portion, the cross-sectional shape of the grooves can be various, and is preferably triangular or trapezoidal or long-strip-shaped, which can be selected according to actual needs.

[0013] Further, the distance from the vertexes of the grooves to the central axis of the chassis portion is 1.1-1.7 times the radius of the insertion shaft portion in the radial direction of the insertion shaft portion, so that the strength requirement during normal use of the button and the requirement that the button is easily broken during disassembly are both satisfied.

[0014] Further, the cross-sectional shape of the grooves is triangular, and more specifically, the groove wall includes an inner groove wall, an outer groove wall distributed on the outer circumferential side of the inner groove wall, and a circular-arc transition groove wall connected between the vertexes of the inner groove wall and the outer groove wall, the inner groove wall extends obliquely away from the circular-arc transition groove wall and toward the central axis of the chassis portion, and the outer groove wall extends obliquely away from the circular-arc transition groove wall and away from the central axis of the chassis portion. In this way, the inner groove wall and the outer groove wall, which are both obliquely arranged in the groove wall, form the inner side and the outer side of the triangular cross section, and the circular-arc transition groove wall is equivalent to the top side of the triangular cross section of the groove after the top vertex of the triangular cross section is rounded. Moreover, the oblique arrangement of the inner groove wall and the outer groove wall of the groove makes the thickness of the chassis portion at the circular-arc transition groove wall the smallest, i.e., the thickness of the thinning portion at the position directly opposite the circular-arc transition groove wall the smallest, so that the chassis portion is more easily broken at the circular-arc transition groove wall during disassembly of the button.

[0015] Further, the inclination angle of the inner groove wall relative to the bottom surface of the chassis portion is greater than the inclination angle of the outer groove wall relative to the bottom surface of the chassis portion. In this way, the cutting edge of the tool can be better fitted at the circular-arc transition groove wall, i.e., the cutting edge of the tool can be better fitted at the position where the thickness of the chassis portion is the thinnest, so that the reliability of the button being disassembled smoothly is improved; meanwhile, the cutting edge of the tool at the top can be appropriately thick and thin, so that the cutting edge is neither too thin to be lost or damaged nor too thick to make the chassis portion difficult to break, so that the durability of the tool and the operability of the button during disassembly are both satisfied.

[0016] Further, along the thickness direction of the bottom plate part, the depth of the groove is 0.6-0.7 times the thickness of the bottom plate part, which meets the requirement that the bottom plate part is easily broken when the button is disassembled by the groove, and avoids the bottom plate part from being accidentally broken at the groove during normal use of the button, and meets the strength requirement during normal use of the button and the requirement that the button is easily broken when disassembled.

[0017] Further, along the radial direction of the insertion shaft part, the distance from the inner wall of the groove to the center axis of the bottom plate part is 1.1-1.2 times the radius of the insertion shaft part, so that the groove and the thinned part are adjacent to the insertion shaft part, and the button can be easily pulled out from the hole of the clothing after being broken when the button is disassembled from the clothing, and the button is not stuck in the clothing, so that the disassembly of the button is easier and smoother.

[0018] Further, the bottom plate part is disc-shaped, and along the radial direction of the insertion shaft part, the width of the groove is 0.2-0.4 times the radius of the bottom plate part, which better meets the strength requirement during normal use of the button and the requirement that the button is easily broken when disassembled.

[0019] Further, the fixed insertion hole is a stepped hole, and the fixed insertion hole includes a plurality of insertion hole segment parts connected in sequence in a direction away from the bottom plate part, and the hole diameter gradually increases. After being arranged in this way, the insertion shaft part and the fixed insertion hole can better engage and better realize the integration of the fixed part and the button body after the fixed part is fixedly connected with the button body. At the same time, when the resin forming accommodation part is used, based on the fixed insertion hole with a stepped hole in the accommodation part, the core rod for forming the fixed insertion hole in the forming mold is a stepped shaft structure that is tapered in sections, which will not bend when taken out of the formed product, and is easier to demold.

[0020] Further, the outer periphery of the part of the insertion shaft part close to the bottom plate part is fixedly provided with a plurality of convex strip parts, the plurality of convex strip parts extend along the axial direction of the insertion shaft part and are spaced apart along the circumferential direction of the insertion shaft part, the plurality of convex strip parts are in interference fit with the fixed insertion hole, the fastening force between the insertion shaft part and the hole wall of the fixed insertion hole is increased, the integration of the fixed part and the button body after the fixed part is fixedly connected with the button body is better, and the adverse phenomenon of relative rotation of the fixed part and the button body after the fixed part is fixedly connected with the button body is reliably avoided.

[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 this utility model 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, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0074] The utility model relates to a kind of buttons, which can be used for clothes, jeans, work pants, luggage and other articles. As shown in Figure 2 And Figure 14 After the button is fixed on the clothing 110 of the article, the button has a front face facing the outside of the article and a back face facing the inside of the article. For ease of description, in the following embodiments, the end of the button provided with the front face is defined as the top end, the end of the button provided 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 As shown in the view, the upper side of the paper is the upward direction, and the lower side of the paper is the downward direction. Therefore, the front face of the button is the top face of the upper end of the button, and the back face of the button is the bottom face of the lower end of the button.

[0075] As shown in Figure 1 And Figure 2 The button according to the utility model comprises a button body 100 and a fixing member 200. As shown in Figures 3 to 5 The button body 100 is provided with a fixing hole 41 extending upward and downward, and the lower end of the fixing hole 41 extends downward to the bottom of the button body 100, so that the opening of the fixing hole 41 faces downward. As shown in Figures 6 to 8 The fixing member 200 comprises an insertion shaft part 50 extending axially along the upward and downward direction and a bottom disc part 60 fixed at the bottom of the insertion shaft part 50. The bottom disc part 60 is disc-shaped, and the insertion shaft part 50 is used to be inserted upward from the lower end of the fixing hole 41 into the fixing hole 41 until the insertion shaft part 50 is fixed in the fixing hole 41, thereby fixing the fixing member 200 in the button body 100. In particular, the fixing member 200 is provided with a groove 61 on the bottom surface of the bottom disc part 60, and the groove 61 is recessed upward in the direction of the button body 100. After the upwardly recessed groove 61 is provided on the bottom disc part 60, the thickness of the bottom disc part 60 at the groove 61 is thinned, so that the bottom disc part 60 is provided with a thinned part 62 axially opposite to the groove 61, i.e., the part of the bottom disc part 60 distributed above the groove 61 constitutes the thinned part 62, and the thinned part 62 is distributed on the outer circumferential side of the insertion shaft part 50.

[0076] The button body 100 and the fixing member 200 are two separate components when the button is not installed. When the button is installed on the fabric 110 of the article, the button body 100 is placed on the front side of the fabric 110, and the fixing member 200 is placed on the back side of the fabric 110, so that the button body 100 and the fixing member 200 are separated by the fabric 110; then, the insertion shaft part 50 of the fixing member 200 is inserted into the hole position on the fabric 110 and the fixing insertion hole 41 of the button body 100 in sequence until the insertion shaft part 50 is inserted into the fixing insertion hole 41, at which time, as shown in Figure 13 , the insertion shaft part 50 of the fixing member 200 is fixedly inserted into the fixing insertion hole 41 of the button body 100, achieving fixed connection between the fixing member 200 and the button body 100, and also clamping the fabric 110 between the bottom disc part 60 of the fixing member 200 and the button body 100, thereby fixing the button as a whole on the fabric 110. Preferably, when the button is installed, a button presser can be used to press and fix the insertion shaft part 50 of the fixing member 200 into the fixing insertion hole 41 of the button body 100.

[0077] The provision of the upwardly recessed groove 61 on the bottom surface of the fixing member 200 makes the bottom disc part 60 of the fixing member 200 have a thinned part 62 with reduced thickness on the upper side of the groove 61, so that the strength of the fixing member 200 at the thinned part 62 is lower, and the bottom disc part 60 of the fixing member 200 is easily broken at the thinned part 62 under external force. Based on this, when the fabric 110 of the article is subjected to recycling treatment, and a tool such as a knife 70 is used to disassemble the button on the fabric 110, as shown in Figure 14 , the upper end of the knife 70 is a blade tip 71, the blade tip 71 of the upper end of the knife 70 is inserted into the groove 61 on the bottom surface of the bottom disc part 60, the blade tip 71 of the knife 70 abuts against the bottom of the thinned part 62, and the bottom disc part 60 of the fixing member 200 is upwardly impacted by the knife 70; since the blade tip 71 after impacting the bottom disc part 60 of the fixing member 200 abuts against the thinned part 62, and the strength of the bottom disc part 60 at the thinned part 62 is lower, after the bottom disc part 60 is upwardly impacted by the knife 70 at the bottom of the thinned part 62, the bottom disc part 60 is easily broken at the thinned part 62. After the bottom disc part 60 is broken, as shown in Figure 15 , the button is split into two parts, which are defined as a first part 81 and a second part 82, the first part 81 is the part of the bottom disc part 60 distributed on the outer peripheral side of the broken part, the first part 81 is in the form of a circular ring and is in a separable state with the fabric 110 after being broken; the second part 82 is the button body 100, the insertion shaft part 50 fixed in the button body 100, and the part of the bottom disc part 60 fixed to the outer periphery of the insertion shaft part 50 and distributed on the inner peripheral side of the broken part. Finally, the first part 81 is removed, and the second part 82 with the button body 100 is pulled out upwardly from the hole position of the fabric 110, so that the button is disassembled from the fabric 110, and the fabric 110 can be subjected to subsequent recycling treatment.

[0078] Therefore, the application is easy to realize the dismounting of the button from the clothing 110 by setting the groove 61 and the thinning part 62 on the chassis part 60 of the fixing part 200, so that the chassis part 60 is easy to break into two parts at the thinning part 62; and the application is also easy to realize and low in cost to process the groove 61 on the chassis part 60, which is conducive to reducing the overall cost of the button. Finally, the application realizes the dismounting of the button from the clothing 110 at low cost and easily.

[0079] Further, as shown in Figures 3 to 5 , the button body 100 includes a shell part 30 constituting a button shell, and a receiving part 40 fixed inside the shell part 30, and a fixed insertion hole 41 is provided in the receiving part 40 and penetrates the receiving part 40 in the up-down direction. The shell part 30 includes a fixed shell surface shell part 31 and a shell base part 32, both of which are formed by metal drawing processing, so that the material of the shell part 30 is metal, and the metal shell part 30 brings better appearance to the button, and also makes the button durable. The receiving part 40 includes an up-down extending columnar base 42, and a flange part 43 extending radially outward from the top of the columnar base 42, and the flange part 43 is disc-shaped; the shell surface shell part 31 is encapsulated on the top of the flange part 43, and this part of the shell surface shell part 31 is disc-shaped, so that the shell surface shell part 31 seals the upper end opening of the fixed insertion hole 41; at the same time, the shell base part 32 is encapsulated on the bottom and outer periphery of the flange part 43, and the fixed connection part of the shell surface shell part 31 and the shell base part 32 is distributed on the outer periphery side of the flange part 43, and a part of the lower end of the columnar base 42 extends downward from the lower end of the shell base part 32. In addition, in other embodiments, the receiving part 40 can only include the columnar base 42.

[0080] Further, the specific shape of the columnar base 42 is not particularly limited, so that the columnar base 42 can have various shapes. In this embodiment, preferably, as shown in Figure 5 , the receiving part 40 is provided with a fixed step part 44 at the outer periphery of the columnar base 42, and the lower end of the shell base part 32 extends inwardly at the fixed step part 44, thereby forming a clamping part 321 clamped inwardly into the columnar base 42, improving the fixing reliability between the shell base part 32 and the receiving part 40.

[0081] Further, the receiving part 40 is made of a material softer than the shell part 30, for example, the receiving part 40 is made by resin injection molding, which is convenient for processing and manufacturing the receiving part 40. In addition, as shown in Figure 5 , the fixed insertion hole 41 is a stepped hole, and the fixed insertion hole 41 includes a plurality of insertion hole segmented parts 411 connected in sequence from bottom to top in the direction away from the chassis part 60, and the hole 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, the vertexes of the grooves 61 are distributed on the outer periphery of the insertion shaft portion 50 in the radial direction of the insertion shaft portion 50; specifically, a parallel line S is drawn from the vertex (i.e. the highest point) of the groove 61, which is parallel to the central axis of the insertion shaft portion 50, and the parallel line S is distributed on the outer periphery of the insertion shaft portion 50 (including the following convex strip portion 51) without going inward beyond the outer peripheral surface of the insertion shaft portion 50 (including the following convex strip portion 51). In this way, the vertexes of the grooves 61 are slightly away from the insertion shaft portion 50 in the radial direction of the insertion shaft portion 50, so that the breaking at the thinning portion 62 can be achieved more simply. Preferably, the distance M from the vertexes of the grooves 61 (i.e. the highest points of the following circular-arc transition groove wall 613) to the central axis of the base portion 60 is greater than the radius R1 of the insertion shaft portion 50 in the radial direction of the insertion shaft portion 50; specifically, the distance M from the vertexes of the grooves 61 to the central axis of the base portion 60 is 1.1-1.7 times the radius R1 of the insertion shaft portion 50, so that the vertexes of the grooves 61 are close to the outer peripheral surface of the insertion shaft portion 50 but do not go inward beyond the outer peripheral surface of the insertion shaft portion 50, thereby better balancing the strength requirement in normal use of the button and the requirement that the button is easily broken when disassembled.

[0085] Further, based on the structure that the vertexes of the grooves 61 do not go inward beyond the insertion shaft portion 50, the cross-sectional shape of the grooves 61 can be various or any shape. The cross-sectional shape of the grooves 61 is preferably a Figure 8 triangle as shown, or a Figure 10 right-angled triangle as shown, or a Figure 11 strip as shown, or a Figure 12 trapezoid as shown, which can be selected according to actual requirements. In the embodiment, the grooves 61 are a circular groove as shown, and the cross-sectional shape of the grooves 61 is a triangle as shown. In other embodiments, the cross-sectional shape of the grooves 61 can also be an irregular quadrilateral or a trapezoid with asymmetric left and right waists. Figure 6 Figure 8 Further, as shown in

[0086] Further, as shown in Figures 6 to 8 ​As 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 comprises an inner groove wall 611, an outer groove wall 612 distributed on the outer circumferential side of the inner groove wall 611, and a circular arc transition groove wall 613 connected between the top ends of the inner groove wall 611 and the outer groove wall 612, the inner groove wall 611 extends in a manner that the farther away from the circular arc transition groove wall 613, the closer to the central axis of the chassis portion 60, the outer groove wall 612 extends in a manner that the farther away from the circular arc transition groove wall 613, the farther away from the central axis of the chassis portion 60, that is, the lower end of the inner groove wall 611 extends in a manner that inclines inwardly and downwardly, the lower end of the outer groove wall 612 extends in a manner that inclines outwardly and downwardly, and the inclination directions of the inner groove wall 611 and the outer groove wall 612 are opposite. After being thus arranged, the inner groove wall 611 and the outer groove wall 612, which are both arranged in an inclined manner, of the groove wall of the groove 61 form an inner side and an outer side of a triangular cross section, and the circular arc transition groove wall 613 is equivalent to a top side of the groove 61 with a triangular cross section after being rounded at the top end thereof. The inclination manner of the inner groove wall 611 and the outer groove wall 612 of the groove 61 makes the thickness of the chassis portion 60 at the circular arc transition groove wall 613 minimum, that is, the thinned portion 62 has the minimum thickness at the position directly opposite to the circular arc transition groove wall 613, and it is easier for the chassis portion 60 to be broken at the circular arc transition groove wall 613 when the button is disassembled.

[0089] Preferably, as shown in the drawings, Figure 9 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 the embodiment, the inclination angle β of the inner groove wall 611 relative to the bottom surface of the chassis portion 60 is 65°-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°-40°, preferably 32°. When the button is disassembled, as shown in the drawings, Figure 14 the tool bit 71 at the top of the tool 70 abuts against the circular arc transition groove wall 613, and the top outer circumferential surface of the tool 70 abuts or is 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 chassis portion 60 is small, and the inclination direction of the inner groove wall 611 is opposite to that of the outer groove wall 612, the tool bit 71 of the tool 70 can better abut at the circular arc transition groove wall 613, that is, the tool bit 71 of the tool 70 can better abut at the position where the chassis portion 60 has the minimum thickness, and the reliability of the button being disassembled smoothly is improved. At the same time, the tool bit 71 at the top of the tool 70 can be appropriately thick and thin, that is, the tool bit 71 can neither be too thin to be lost or damaged, nor be too thick to make the chassis portion 60 difficult to be broken, and the durability of the tool 70 and the operability of the button disassembly are both considered.

[0090] Preferably, as shown in the drawings, Figure 14As shown, the inside of the cutter 70 is provided with a relief groove 72, the upper end of the relief groove 72 extends upward to the top surface of the cutter 70, and the upper end of the relief groove 72 is open toward the bottom plate part 60. The size of the opening of the relief groove 72 should meet: it can accommodate the part of the bottom plate part 60 on the inner circumferential side of the groove 61, and allow the nose 71 to abut against the circular arc transition groove wall 613 of the groove 61.

[0091] Further, as shown in Figure 6 and Figure 7 , the outer periphery of the insertion shaft part 50 near the part of the bottom plate part 60 is fixedly provided with a plurality of convex strip parts 51, the plurality of convex strip parts 51 extend along the axial direction of the insertion shaft part 50 and are spaced apart along the circumferential direction of the insertion shaft part 50, the plurality of convex strip parts 51 are in interference fit with the fixed insertion hole 41, which increases the fastening force between the insertion shaft part 50 and the hole wall of the fixed insertion hole 41, better realizes the integration after the fixed part 200 and the button body 100 are fixedly connected, and reliably avoids the adverse phenomenon of relative rotation after the fixed part 200 and the button body 100 are fixedly connected.

[0092] Further, as shown in Figure 4 , the bottom surface of the accommodating part 40 is provided with a plurality of limiting protruding strips 45 which protrude downward and are spaced apart in the circumferential direction, as shown in Figure 6 , the top surface of the bottom plate part 60 is provided with an annular concave-convex 63 and a plurality of limiting protrusions 64 distributed on the inner circumferential side of the annular concave-convex 63. After the button is fixed on the clothing 110, the limiting protruding strips 45 and the limiting protrusions 64 are oppositely arranged through the clothing 110, preventing the button body 100 and the fixed part 200 from rotating relative to the clothing 110.

[0093] Further, as shown in Figure 6 and Figure 7 , the fixed part 200 is provided with a conical insertion guide part 52 at the top of the insertion shaft part 50, the setting of the tip of the upper end of the insertion guide part 52 facilitates the insertion of the insertion shaft part 50 into the fixed insertion hole 41. At the same time, the outer diameter of the lower end of the insertion guide part 52 is larger than the outer diameter of the insertion shaft part 50, thereby forming a stop part 53 provided at the lower end of the insertion guide part 52, so that the insertion shaft part 50 is better engaged with the accommodating part 40.
