[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Existing electronic devices often require the use of spring clips to electrically connect different components or support parts. In related technologies, to facilitate production, transportation, and assembly, the spring clips are often connected to a connecting material. After the spring clips are assembled into the product, the connecting material must be removed. Separating the spring clips from the connecting material typically involves manually breaking the connecting material off the spring clips.

[0042] However, when the connecting material is annular and arranged around the spring sheet, it is difficult for the operator to grasp the spring sheet, and the relative movement of the connecting material and the spring sheet in the horizontal direction is mutually restricted. At the same time, after the spring sheet is installed on the product, the travel of the connecting material on the side facing the product will be restricted. If the connecting material is bent and broken to the side away from the product, the angle of the bending of the connecting material is large and it is not easy to break off. Due to the above problems, it is very difficult for the operator to separate the spring sheet and the connecting material by hand, the production efficiency is low, and the spring sheet is easily damaged. Using automated equipment to separate the spring sheet and the annular connecting material has the problems of long automation design cycle and high production cost.

[0043] Based on the above concepts and problems, the present invention provides a breaking device 100. This breaking device 100 is used to separate the spring piece 7 of the spring piece structure 200 from the connecting material 8. It is understood that when the spring piece 7 of the spring piece structure 200 is welded to an electronic device, the connecting material 8 is required to facilitate alignment or positioning with the electronic device so as to align the spring piece 7 of the spring piece structure 200 with the electronic device.

[0044] In this embodiment, the connecting material 8 of the spring structure 200 is provided with an escape opening 81 and a connecting arm 82 located at the escape opening 81. The spring piece 7 is provided corresponding to the escape opening 81 and is connected to the connecting arm 82. It is understood that the spring piece 7 and the connecting material 8 are connected by the connecting arm 82. The connecting arm 82 is configured as a thin-walled structure or has a notch provided therein. When stress is concentrated on the connecting arm 82, the connecting arm 82 is prone to fracture, thereby separating the connecting material 8 from the spring piece 7. When the connecting material 8 and the spring piece 7 are separated, the spring piece 7 is connected to the product.

[0045] It should be noted that the structure of the separating connecting material 8 and the spring piece 7 in the figure is only for illustration and is not intended to be a limiting structure of the product of the present invention.

[0046] Please refer to Figures 1 to 9 As shown, in an embodiment of the present invention, the breaking device 100 includes a base 1, a first pressure block 2 and a breaking assembly 3, the base 1 has a placement surface 111 and a sliding cavity 112 passing through the placement surface 111; the first pressure block 2 is movably connected to the base 1, and the first pressure block 2 is provided with a pressing arm 23, which is used to pass through the avoidance opening 81 and press the spring piece 7 to the placement surface 111; the breaking assembly 3 is movably arranged in the sliding cavity 112, and the breaking assembly 3 is provided with a limiting cavity 33 for limiting the connecting material 8; wherein, the breaking assembly 3 moves along the sliding cavity 112, and drives the connecting material 8 to pull the connecting arm 82 to move, so that the connecting arm 82 is broken and separated from the spring piece 7.

[0047] In this embodiment, the base 1 and the first pressure block 2 cooperate to press the spring piece 7 to fix the position of the spring piece 7. It can be understood that the base 1 and the first pressure block 2 press the spring piece 7 close to one end of the connecting arm 82 so that the stress is concentrated on the connecting arm 82 to prevent the spring piece 7 from being damaged. One end of the connecting material 8 is limited in the limiting cavity 33 of the breaking assembly 3. When the spring piece 7 and the connecting material 8 are fixed in place, the operator moves the breaking assembly 3 along the sliding cavity 112 to drive the connecting material 8 to move relative to the spring piece 7 to pull the connecting arm 82 until the connecting arm 82 breaks and the connecting material 8 and the spring piece 7 are separated. In this way, the operator accurately presses the spring piece 7 and the connecting material 8 with the help of the breaking device 100, and moves the connecting material 8 and the spring piece 7 relative to each other in a preset direction, thereby preventing damage to the spring piece 7 and improving the efficiency of breaking the connecting material 8 and the spring piece 7.

[0048] It is understandable that when the connecting material 8 and the spring sheet 7 are separated, the spring sheet 7 and the connected product are compressed and fixed together between the first pressing block 2 and the base 1. The product is located on the side of the spring sheet 7 close to the base 1, and the pressing arm 23 passes through the avoidance opening 81 formed by the connecting material 8, pressing the side of the spring sheet 7 away from the product.

[0049] Optionally, the first pressing block 2 and the base 1 can be slidably connected by a guide rod or a slide rail, and the sliding direction is set at an angle to the placement surface 111, or the first pressing block 2 and the base 1 are rotatably connected by a hinge or a rotating shaft, or the first pressing block 2 and the base 1 can be detachably set. In this way, the first pressing block 2 and the base 1 can be relatively separated, so that the operator can place the spring piece 7 on the placement surface 111. When the spring piece 7 is in place, the operator moves the first pressing block 2 to the side of the spring piece 7 away from the placement surface 111, and relatively locks the first pressing block 2 and the base 1 with a locking member such as a bolt or a buckle, thereby compressing the spring piece 7 located between the pressing arm 23 and the base 1.

[0050] In one embodiment, if Figure 4 As shown, the sliding cavity 112 extends along the first direction, and the first direction forms an angle α with the placement surface 111, 0°<α<90°. Figure 4 The X direction and angle α are shown in FIG.

[0051] As can be understood, with the horizontal plane as a reference, the connecting material 8 is arranged around the spring 7 on the horizontal plane. The spring 7 and the product are also arranged parallel to the horizontal plane. Simultaneously, the product is located vertically below the spring 7, and the vertical projections of the product and the connecting material 8 at the end away from the limiting cavity 33 at least partially overlap. When separating the connecting material 8 and the spring 7, the placement surface 111 is placed parallel to the horizontal plane to smoothly compress the product and the spring 7 and prevent deformation of the spring 7. At this time, the horizontal travel of the connecting material 8 is limited by the connecting material 8, resulting in a very small horizontal movement. Simultaneously, the downward vertical travel of the connecting material 8 is blocked by the product, preventing downward movement. Therefore, the first direction is arranged at an angle to the placement surface 111 and is not perpendicular. When the separating assembly 3 drives the connecting material 8 in the first direction, the connecting material 8 has both a horizontal displacement component and a vertical movement component. This allows the connecting material 8 to have a large travel within a relatively small space, facilitating separation of the connecting material 8 from the spring 7. When the connecting material 8 and the spring piece 7 are separated, the separating assembly 3 drives the connecting material 8 to move away from the placement surface 111 , that is, the moving component of the connecting material 8 in the vertical direction is vertically upward.

[0052] Optionally, the spring piece 7 and the connecting material 8 are arranged parallel and not coplanar, and the connecting material 8 is located on the side of the spring piece 7 away from the placement surface 111. At the same time, the connecting arm 82 is arranged on the side of the spring piece 7 away from the limiting cavity 33 and is inclined relative to the placement surface 111 to connect the spring piece 7 and the connecting material 8. When the connecting material 8 and the spring piece 7 are separated, the breaking assembly 3 drives the connecting material 8 to move away from the connecting arm 82, so that the connecting arm 82 will bend, and the stress is more likely to be concentrated on the connecting arm 82, which is conducive to the breaking of the connecting arm 82, thereby improving the stability and reliability of the operator's use of the breaking device 100 to separate the spring piece 7 and the connecting material 8.

[0053] Optionally, the angle α is 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, etc., which is not limited here.

[0054] In one embodiment, the first pressure block 2 includes a mounting portion 21 and an extension portion 22, the mounting portion 21 is detachably connected to the base 1, one end of the extension portion 22 is connected to the mounting portion 21, and the other end of the extension portion 22 is provided with a pressure arm 23, and an avoidance space 24 is formed between the mounting portion 21, the extension portion 22 and the pressure arm 23, and the avoidance space 24 is used to avoid the connecting material 8.

[0055] In this embodiment, if Figure 1 、 Figure 5 and Figure 9 As shown, the mounting portion 21 is detachably connected to the base 1. When placing the spring piece 7, the first pressing block 2 and the base 1 are completely separated to facilitate the operator to accurately place the spring piece 7. After the spring piece 7 is in place, the mounting portion 21 is connected to the base 1 so that the pressing arm 23 and the base 1 press the spring piece 7 relative to each other. The pressing arm 23 is connected to the mounting portion 21 through the extension portion 22, so that there is a certain distance between the pressing arm 23 and the mounting portion 21, and a clearance space 24 is formed between the pressing arm 23 and the mounting portion 21. In this way, the pressing arm 23 can extend into the avoidance opening 81 of the connecting material 8 to press the spring piece 7, and the second pressing block 32 will not press the connecting material 8. When the breaking assembly 3 drives the connecting material 8 to move along the first direction, the clearance space 24 provides sufficient space for the connecting material 8 to move, thereby preventing the connecting material 8 from contacting the first pressing block 2 during the movement, causing the connecting material 8 to be unable to move into place, affecting the breaking effect of the breaking device 100 on the connecting material 8 and the spring piece 7.

[0056] It can be understood that the avoidance space 24 is used to avoid the end of the connecting material 8 from being away from the limiting cavity 33. In actual implementation, the mounting portion 21 is connected to the placement surface 111 of the base 1. In the projection parallel to the placement surface 111, the mounting portion 21 and the connecting portion are convex. Optionally, the mounting portion 21 is arranged in a door shape, with both ends of the mounting portion 21 connected to the base 1, the middle part of the mounting portion 21 is spaced apart from the placement surface 111, and one end of the extension portion 22 is connected to the middle part of the mounting portion 21. In this way, the size of the avoidance space 24 formed between the mounting portion 21, the extension portion 22 and the pressing arm 23 can be increased, further improving the avoidance effect on the connecting material 8, and also making it easier for the operator to observe whether the pressing arm 23 presses the spring piece 7 into place.

[0057] Optionally, the mounting portion 21 is provided with a first through-hole 211, and the base 1 is provided with a first threaded hole 113. The first fixing bolt 4 passes through the first through-hole 211 and is connected to the first threaded hole 113. At the same time, the nut of the first fixing bolt 4 abuts against the side of the mounting portion 21 away from the base 1, thereby connecting the first pressure block 2 to the base 1 and causing the pressing arm 23 to press against the spring piece 7 relative to the abutting surface. It is understood that at least two groups of the first fixing bolt 4, the first through-hole 211, and the first threaded hole 113 can be provided to prevent relative rotation between the mounting portion 21 and the base 1, further improving the stability of the connection between the first pressure block 2 and the base 1.

[0058] In one embodiment, the pressing arm 23 has a pressing surface 231 and a first avoiding surface 232 arranged at an angle. The first avoiding surface 232 is located on the side of the pressing arm 23 facing the avoiding space 24. The pressing surface 231 is used to cooperate with the placement surface 111 to press the spring piece 7. The first avoiding surface 232 and the pressing surface 231 form an angle β, 0°<β<90°. Figure 4 shown.

[0059] In this embodiment, if Figure 1 、 Figure 5 、 Figure 6 and Figure 9 As shown, when the breaking assembly 3 drives one end of the connecting material 8 to move along the extension direction of the sliding cavity 112, the end of the connecting material 8 located in the avoidance space 24 is also driven to move along the extension direction of the sliding cavity 112. In order to avoid the end of the connecting material 8 located in the avoidance space 24, the first avoidance surface 232 of the pressing arm 23 facing the avoidance space 24 is also set at an angle to the pressing surface 231 and is not set perpendicularly. The pressing surface 231 of the pressing arm 23 cooperates with the placement surface 111 to press the spring piece 7. Optionally, the pressing surface 231 is set parallel to the placement surface 111 to ensure that the pressing surface 231 and the placement surface 111 are tightly pressed against the spring piece 7, thereby preventing the spring piece 7 from moving during the breaking process.

[0060] Optionally, the angle β is 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, etc., which is not limited here.

[0061] It is understood that the first avoidance surface 232 and the sliding cavity 112 are respectively located on either side of the pressing arm 23, and the angle β formed by the first avoidance surface 232 and the pressing surface 231 is not greater than the angle α formed by the first direction and the pressing surface 231. In this way, the first avoidance surface 232 will not hinder the movement of the continuous material 8 when the continuous material 8 is driven by the breaking assembly 3 along the first direction. Optionally, the first avoidance surface 232 is arranged parallel to the first direction.

[0062] Optionally, the pressing arm 23 further has a second avoidance surface 233, which is located on the side of the pressing arm 23 facing away from the avoidance space 24 and is connected to the end of the pressing surface 231 away from the first avoidance surface 232. The second avoidance surface 233 is used to avoid the bending structure of the spring piece 7.

[0063] Understandably, Figure 8 As shown, the spring clip 7 is usually bent to increase the elasticity of the spring clip 7 and adapt to different connection positions. The spring clip 7 can be divided into at least two parts based on the bending structure of the spring clip 7. When breaking apart, in order to concentrate stress on the connecting arm 82, the pressing surface 231 and the placement surface 111 cooperate to press the portion of the spring clip 7 close to the connecting arm 82. The portion of the spring clip 7 close to the connecting arm 82 is connected to the product. The pressing surface 231 covers the portion of the spring clip 7 close to the connecting arm 82 to avoid stress concentration in the spring clip 7 when breaking apart, which affects the quality of the spring clip 7. In this embodiment, the connecting arm 82 is located on the side of the spring clip 7 close to the avoidance space 24, and the bending structure of the spring clip 7 is arranged on the side of the abutting arm away from the avoidance space 24. Therefore, the second avoidance surface 233 is located on the side of the abutting arm 23 facing away from the abutting space to avoid the bending structure of the spring clip 7 and prevent the pressing arm 23 from pressing on the bending structure of the spring clip 7, causing deformation of the spring clip 7.

[0064] In order to ensure the overall strength of the pressing arm 23, the second avoidance surface 233 is also set at an inclined angle to the pressing surface 231, and the angle is smaller than the angle β formed by the first avoidance surface 232 and the pressing surface 231, so that the cross-sectional area of ​​the pressing arm 23 gradually increases from the end close to the placing surface 111 to the end away from the placing surface 111, at least in the part close to the placing surface 111.

[0065] In actual implementation, the connecting arm 82 is located on the side of the spring piece 7 close to the avoidance space 24, one end of the pressing arm 23 is connected to the protruding portion 22, and the other end of the pressing arm 23 is bent toward the mounting portion 21. The end face of the pressing arm 23 forms a pressing surface 231, and the two side walls of the pressing arm 23 facing and away from the avoidance space 24 form a first avoidance surface 232 and a second avoidance surface 233.

[0066] In one embodiment, the breaking assembly 3 includes a slider 31 and a second pressure block 32 . The slider 31 is movably disposed in the sliding cavity 112 . The second pressure block 32 is movably connected to the slider 31 and encloses the slider 31 to form a limiting cavity 33 .

[0067] Understandably, Figure 1 、 Figure 2 and Figure 7As shown, the slider 31 and the second pressing block 32 cooperate to press the connecting material 8 to compress and fix the connecting material 8, thereby enabling the breaking assembly 3 to drive the connecting material 8 to move. The slider 31 is limited in position by abutting against the side wall of the sliding cavity 112 within the sliding cavity 112, so that the slider 31 moves along the extension direction of the sliding cavity 112. At the beginning of the separation, the slider 31 abuts against the bottom wall of the sliding cavity 112 away from the placement surface 111. The end surface of the slider 31 away from the base 1 forms a material placement surface 312. When the spring piece 7 is placed on the placement surface 111, the material 8 is also placed on the material placement surface 312. The operator then uses the pressing arm 23 and the placement surface 111 to press the spring piece 7, and uses the second pressing block 32 and the material placement surface 312 to press the material 8, completing the pressing and fixing of the spring piece 7 and the material 8. The operator then moves the slider 31 along the extension direction of the sliding cavity 112 to the side away from the base 1 to drive the material 8 to move relative to the spring piece 7, causing the connecting arm 82 to break, and the material 8 and the spring piece 7 to separate. Among them, the second pressing block 32 is provided with a material pressing surface 322 that cooperates with the material placement surface 312. The material pressing surface 322 and the material placement surface 312 are arranged parallel to the material 8 to ensure the stability of the pressing of the material 8.

[0068] Alternatively, the second pressing block 32 and the slider 31 may be slidably connected via a guide rod or a slide rail, with the sliding direction being angled relative to the placement surface 111. Alternatively, the second pressing block 32 and the slider 31 may be rotatably connected via a hinge or a rotating shaft, or the second pressing block 32 and the slider 31 may be detachably arranged. After the connecting material 8 is placed on the slider 31, the operator moves the second pressing block 32 to the side of the connecting material 8 facing away from the slider 31 and locks the second pressing block 32 and the slider 31 relative to each other using a locking member such as a bolt or a buckle, thereby compressing the connecting material 8.

[0069] In this embodiment, the second pressure block 32 and the slider 31 are detachably connected via a second fixing bolt 35. The second pressure block 32 is provided with a second through-hole 323, and the slider 31 is provided with a second threaded hole 313. The second fixing bolt 35 passes through the second through-hole 323 and connects to the second threaded hole 313, so that the second pressure block 32 and the slider 31 enclose a limiting cavity 33. It is understood that at least two sets of second fixing bolts 35, second through-holes 323, and second threaded holes 313 can be provided to improve the stability of the connection between the second pressure block 32 and the slider 31.

[0070] In one embodiment, if Figures 1 to 3 As shown, the breaking assembly 3 further includes a pulling member 34 , which is connected to the slider 31 ; wherein, pulling the pulling member 34 drives the slider 31 to move along the sliding cavity 112 .

[0071] It is understandable that when the slider 31 is located in the sliding cavity 112, it is difficult for the operator to directly move the slider 31. In this embodiment, the operator uses the puller 34 to drive the slider 31 to move along the extension direction of the sliding cavity 112, thereby improving the operator's convenience and improving production efficiency.

[0072] Optionally, the puller 34 is rod-shaped or stick-shaped, with one end of the puller 34 connected to the slider 31 and the other end of the puller 34 extending out of the sliding cavity 112 for the operator to hold. A rubber layer may also be provided on the puller 34 to facilitate the operator's holding.

[0073] In this embodiment, the pulling member 34 extends from the sliding cavity 112 through the cavity opening of the placement surface 111, and the extension direction of the pulling member 34 is parallel to the extension direction of the sliding cavity 112, that is, the moving direction of the slider 31, so that the operator can apply force to the slider 31 along the extension direction of the sliding cavity 112, thereby reducing the sliding resistance of the slider 31 in the sliding cavity 112 and improving the stability of the breaking component 3 in driving the continuous material 8 to move.

[0074] Optionally, the puller 34 is an auxiliary bolt. The slider 31 is provided with a mounting surface 314 and a threaded hole provided on the mounting surface 314. When the slider 31 is installed in the sliding cavity 112, the auxiliary bolt is connected to the threaded hole, and the nut end of the auxiliary bolt extends out of the sliding cavity 112 for the operator to grasp. The auxiliary bolt is connected to the middle position of the slider 31. In this way, when the operator pulls the puller 34, the force on the slider 31 is balanced, and the movement is smooth. The mounting surface 314 is arranged perpendicular to the extension direction of the sliding cavity 112, so that the auxiliary bolt connected to the mounting surface 314 can be arranged along the extension direction of the sliding cavity 112.

[0075] In one embodiment, the slider 31 is provided with a first positioning pin 311 , the second pressing block 32 is provided with a first positioning hole 321 , and the first positioning pin 311 is passed through the first positioning hole 321 .

[0076] In this embodiment, if Figure 2 、 Figure 7 and Figure 9 As shown, the slider 31 and the second pressing block 32 are positioned and assembled by the limiting cooperation between the first positioning pin 311 and the first positioning hole 321 so as to accurately press the connecting material 8 relative to each other.

[0077] Optionally, a positioning hole 83 is provided on the connecting material 8, and one end of the first positioning pin 311 passes through the positioning hole 83 and is retained in the first positioning hole 321, thereby achieving the positioning and placement of the connecting material 8 and the spring piece 7. Multiple groups of first positioning pins 311, positioning holes 83, and first positioning holes 321 are provided to achieve the fixed placement of the connecting material 8 and the spring piece 7 and prevent the connecting material 8 and the spring piece 7 from rotating about the first positioning pin 311.

[0078] Optionally, the slider 31 is provided with a first mounting hole 315 , one end of the first positioning pin 311 is limited in the first mounting hole 315 , and the other end of the first positioning pin 311 is limited in the first positioning hole 321 of the second pressing block 32 .

[0079] In one embodiment, if Figure 1 、 Figure 3 and Figure 4 As shown, the base 1 is provided with an avoidance groove 121 corresponding to the pulling member 34 , and one end of the pulling member 34 away from the slider 31 passes through the avoidance groove 121 .

[0080] It is understood that the end of the puller 34 away from the slider 31 needs to extend out of the sliding cavity 112 and as far away from the base 1 as possible to facilitate the operator's grip on the puller 34. Therefore, the base 1 is provided with an escape groove 121 to avoid the puller 34, allowing the end of the puller 34 away from the slider 31 to extend out of the sliding cavity 112.

[0081] Optionally, the avoidance groove 121 is connected to the sliding cavity 112 and can be set on a side of the sliding cavity 112 close to the placement surface 111, that is, the pulling member 34 extends from the top of the sliding cavity 112 to facilitate the operator to pull the pulling member 34.

[0082] In one embodiment, the base 1 includes a main body 11 and a limiting portion 12. The main body 11 is provided with a placement surface 111 and a sliding cavity 112. The main body 11 is movably connected to the first pressure block 2. The limiting portion 12 is connected to the main body 11 and extends toward the cavity opening of the sliding cavity 112. The limiting portion 12 is used to limit the travel of the breaking component 3 in the sliding cavity 112.

[0083] It can be understood that the sliding cavity 112 extends along the first direction and passes through the placement surface 111 to form a cavity opening, so that part of the slider 31 extends out of the sliding cavity 112; or, the connecting material 8 extends into the sliding cavity 112, so that the connecting material 8 can be placed on the connecting material placement surface 312 of the slider 31. At the same time, the second pressing block 32 is also connected to the slider 31 through the cavity opening to press the connecting material 8.

[0084] In this embodiment, the two ends of the slider 31 along the first direction can cooperate with the bottom wall of the sliding cavity 112 away from the cavity opening and the limiting portion 12 to limit. When the slider 31 moves along the first direction in the sliding cavity 112, the starting point of the moving stroke of the slider 31 is limited by the limiting portion 12, and the end point of the moving stroke of the slider 31 is limited by the bottom wall of the sliding cavity 112 away from the cavity opening. In this way, the moving stroke of the breaking component 3 can be controlled within a preset range to prevent the operator from moving the breaking component 3 too large or too small, which affects the breaking effect.

[0085] Optionally, the limiting portion 12 is provided with a avoiding groove for avoiding the pulling member 34, and a limiting surface 122 is formed on the side of the limiting portion 12 facing the sliding cavity 112. The limiting surface 122 is arranged parallel to the mounting surface 314 of the sliding block 31 for mounting the pulling member 34. When the slide moves along the first direction to the end point of the moving stroke, the mounting surface 314 is limited by the abutment of the limiting surface 122.

[0086] In one embodiment, the main body 11 is further provided with at least one insertion port 13 communicating with the sliding cavity 112 , and the insertion port 13 is used for allowing the breaking component 3 to be placed into the sliding cavity 112 .

[0087] Understandably, Figure 1 and Figure 6 As shown, the main body 11 has two first side walls and two second side walls. The two first side walls are respectively located on the side of the limiting portion 12 away from the sliding cavity 112 and the side of the placement surface 111 away from the sliding cavity 112. The two first side walls are arranged opposite to each other and are connected to the placement surface 111 at an angle. The two second side walls of the main body 11 are respectively connected to the two first side walls and the placement surface 111 from both sides of the two first side walls. The two second side walls of the main body 11 are also arranged opposite to each other and are connected to the first side walls and the placement surface 111 at an angle.

[0088] In this embodiment, the travel of the slider 31 along the extension direction of the sliding cavity 112 is limited, and the slider 31 cannot be directly inserted into the sliding cavity 112 through the opening of the placement surface 111. Therefore, the operator inserts the slider 31 into the sliding cavity 112 through the insertion opening 13. The insertion opening 13 is provided on the second side wall and is arranged parallel to the extension direction of the sliding cavity 112. The cross-sectional size and shape of the insertion opening 13 match the cross-sectional size and size of the slider 31.

[0089] Optionally, one of the two second side walls is provided with an access opening 13, or both second side walls are provided with an access opening 13. The puller 34 connected to the slider 31 can be configured as a handle. When the slider 31 is placed in the sliding cavity 112, both ends of the puller 34 extend from the access opening 13 into the sliding cavity 112 and connect with the slider 31. The slider 31 can partially extend or leak out of the sliding cavity 112 at the access opening 13, making it easier for the operator to remove the slider 31 from the sliding cavity 112 through the access opening 13.

[0090] In one embodiment, if Figures 1 to 3 and Figure 6 As shown, the breaking device 100 further includes a limiting member 5 , which is detachably connected to the main body 11 and covers at least a portion of the insertion opening 13 .

[0091] It can be understood that in order to prevent the slider 31 from falling out of the insertion port 13 during the process of sliding along the extension direction of the sliding cavity 112, after the slider 31 is placed in the sliding cavity 112, the operator installs the limit member 5 on the main body 11 and covers at least part of the insertion port 13 to prevent the slider 31 from falling out of the insertion port 13.

[0092] Optionally, the limiting member 5 can be detachably connected to the main body 11 by means of bolts or snaps.

[0093] In this embodiment, two inlets 13 are provided, one on each of the two second side walls of the main body 11. Correspondingly, two stoppers 5 are provided. The main body 11 is provided with through-holes extending through the two second side walls. A connecting member 6 is provided through the through-holes, with both ends of the connecting member 6 extending out of the through-holes. The two stoppers 5 are respectively connected to both ends of the connecting member 6 and abut against the two side walls of the slider 31 facing the inlets 13 to limit the slider 31 within the sliding cavity 112. Optionally, the connecting member 6 may be a screw, and the stopper 5 may be threadedly connected to the screw. The stopper 5 may be provided in a disc shape to facilitate the operator's rotation of the stopper 5 to connect or remove the stopper 5 from the screw.

[0094] In one embodiment, if Figure 5 、 Figure 6 and Figure 9 As shown, the base 1 is provided with a second positioning pin 14 , the first pressing block 2 is provided with a second positioning hole 25 , and the second positioning pin 14 is passed through the second positioning hole 25 .

[0095] In this embodiment, the base 1 and the first pressing block 2 are positioned and installed by the limiting cooperation of the second positioning pin 14 and the second positioning hole 25 so as to accurately press the elastic sheet 7 relative to each other.

[0096] Optionally, the base 1 is provided with a second mounting hole 114 , one end of the second positioning pin 14 is limited in the second mounting hole 114 , and the other end of the second positioning pin 14 is limited in the second positioning hole 25 of the first pressing block 2 .

[0097] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
