[0041] Existing electronic devices often need to use spring structures to electrically connect different components or supporting components. In the related art, in order to facilitate production, transportation and assembly, springs are usually connected with connecting materials. When the springs are assembled on the product, the connecting materials need to be removed. The springs and connecting materials are usually separated by the operator manually breaking the connecting materials off the springs.

[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 bending angle 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 ideas and problems, the present invention proposes a breaking device 100. The breaking device 100 is used to separate the spring sheet 7 of the spring sheet structure 200 from the connecting material 8. It can be understood that when the spring sheet 7 of the spring sheet structure 200 is welded to the electronic device, it is necessary to facilitate the alignment or positioning with the electronic device through the connecting material 8 so as to align the spring sheet 7 of the spring sheet structure 200 with the electronic device.

[0044] In this embodiment, the connecting material 8 of the spring sheet structure 200 is provided with an avoidance opening 81 and a connecting arm 82 located at the avoidance opening 81, and the spring sheet 7 is provided corresponding to the avoidance opening 81 and connected to the connecting arm 82. It can be understood that the spring sheet 7 and the connecting material 8 are connected through the connecting arm 82, and the connecting arm 82 is provided with a thin-walled structure or a notch is provided on the connecting arm 82. When the stress is concentrated on the connecting arm 82, the connecting arm 82 is prone to breakage, thereby separating the connecting material 8 from the spring sheet 7. When the connecting material 8 and the spring sheet 7 are separated, the spring sheet 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, and the pressing arm 23 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 pressing block 2 cooperate to press the spring sheet 7 to fix the position of the spring sheet 7. It can be understood that the base 1 and the first pressing block 2 press the spring sheet 7 close to one end of the connecting arm 82 so that the stress is concentrated on the connecting arm 82 to avoid damage to the spring sheet 7. One end of the connecting material 8 is limited in the limiting cavity 33 of the breaking component 3. When the spring sheet 7 and the connecting material 8 are fixed in place, the operator moves the breaking component 3 along the sliding cavity 112 to drive the connecting material 8 to move relative to the spring sheet 7 to pull the connecting arm 82 until the connecting arm 82 breaks, and the connecting material 8 and the spring sheet 7 are separated. In this way, the operator accurately presses the spring sheet 7 and the connecting material 8 with the help of the breaking device 100, and moves the connecting material 8 and the spring sheet 7 relatively in a preset direction, thereby avoiding damage to the spring sheet 7 and improving the efficiency of breaking the connecting material 8 and the spring sheet 7.

[0048] It can be understood that when the connecting material 8 and the spring sheet 7 are separated, the spring sheet 7 and the connected product are pressed 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 with 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 far apart, so that the operator can place the spring sheet 7 on the placement surface 111. When the spring sheet 7 is placed in place, the operator moves the first pressing block 2 to the side of the spring sheet 7 away from the placement surface 111, and relatively locks the first pressing block 2 and the base 1 by means of locking members such as bolts or buckles, thereby compressing the spring sheet 7 between the pressing arm 23 and the base 1.

[0050] In one embodiment, if Figure 4 As shown, the sliding cavity 112 is extended 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] It can be understood that, with the horizontal plane as a reference, the connecting material 8 is arranged around the spring sheet 7 on the horizontal plane, and the spring sheet 7 and the product are also arranged parallel to the horizontal plane. At the same time, the product is located below the spring sheet 7 in the vertical direction, and the projection of the product and the connecting material 8 in the vertical direction at least partially overlap at the end away from the limiting cavity 33. When the connecting material 8 and the spring sheet 7 are separated, the placement surface 111 is placed parallel to the horizontal plane to smoothly press the product and the spring sheet 7 and prevent the spring sheet 7 from deforming. At this time, the stroke of the connecting material 8 in the horizontal direction is limited by the connecting material 8, and the stroke moving in the horizontal direction is very small. At the same time, the downward stroke of the connecting material 8 in the vertical direction is blocked by the product and cannot move downward. Therefore, the first direction is set at an angle with the placement surface 111 and is not set vertically. When the separation component 3 drives the connecting material 8 to move along the first direction, the connecting material 8 has both a displacement component in the horizontal direction and a movement component in the vertical direction. In this way, in a smaller space, the connecting material 8 has a larger movement stroke, so that the connecting material 8 and the spring sheet 7 can be separated. When the connecting material 8 and the spring piece 7 are separated, the separating assembly 3 drives the connecting material 8 to move in a direction 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 in parallel and not in the same plane, 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 separation component 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, and improves the stability and reliability of the operator using 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 pressing 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 Fig. 9 As shown, the mounting portion 21 is detachably connected to the base 1. When placing the spring sheet 7, the first pressing block 2 and the base 1 are completely separated so that the operator can accurately place the spring sheet 7. After the spring sheet 7 is placed 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 sheet 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 an avoidance space 24 is formed between the pressing arm 23 and the mounting portion 21, so that the pressing arm 23 can extend into the avoidance opening 81 of the connecting material 8 to press the spring sheet 7, and the second pressing block 32 will not press the connecting material 8. When the breaking component 3 drives the connecting material 8 to move along the first direction, the avoidance space 24 provides enough space for the connecting material 8 to move, so as to avoid the connecting material 8 from contacting with the first pressing block 2 during the movement, so that the connecting material 8 cannot move into place, affecting the breaking effect of the breaking device 100 on the connecting material 8 and the spring sheet 7.

[0056] It can be understood that the avoidance space 24 is used to avoid the end of the connecting material 8 away from the limiting cavity 33. In actual implementation, the mounting portion 21 is connected to the placement surface 111 of the base 1, and in the projection parallel to the placement surface 111, the mounting portion 21 and the connecting portion are convexly arranged. Optionally, the mounting portion 21 is arranged in a door shape, the two ends of the mounting portion 21 are connected to the base 1, the middle part of the mounting portion 21 is spaced 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 facilitating the operator to observe whether the pressing arm 23 presses the spring sheet 7 into place.

[0057] Optionally, the mounting portion 21 is provided with a first through hole 211, 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, and the nut of the first fixing bolt 4 abuts against the side of the mounting portion 21 away from the base 1, so as to connect the first pressing block 2 with the base 1, and make the pressing arm 23 and the abutting surface press the spring sheet 7 relative to each other. It can be 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 the mounting portion 21 and the base 1 from rotating relative to each other, and further improve the stability of the connection between the first pressing 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 sheet 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 Fig. 9 As shown, when the breaking component 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 with the pressing surface 231, and is not set vertically. The pressing surface 231 of the pressing arm 23 cooperates with the placement surface 111 to press the spring sheet 7. Optionally, the pressing surface 231 is set parallel to the placement surface 111 to ensure the tightness of the pressing surface 231 and the placement surface 111 relative to the spring sheet 7, so as to prevent the spring sheet 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 can be understood that the first avoidance surface 232 and the sliding cavity 112 are respectively located on both sides 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, so that the first avoidance surface 232 will not hinder the movement of the connecting material 8 when the connecting material 8 is driven by the breaking component 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 avoiding surface 233 , which is located on the side of the pressing arm 23 facing away from the avoiding space 24 and connected to an end of the pressing surface 231 away from the first avoiding surface 232 . The second avoiding surface 233 is used to avoid the bending structure of the spring sheet 7 .

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

[0064] In order to ensure the overall strength of the pressing arm 23, the second avoidance surface 233 is also arranged 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 one 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 extending portion 22, and the other end of the pressing arm 23 is bent toward the mounting portion 21, and the end surface 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 pressing block 32 . The slider 31 is movably disposed in the sliding cavity 112 . The second pressing block 32 is movably connected to the slider 31 and encloses the slider 31 to form a limiting cavity 33 .

[0067] Understandable, such as 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 press and fix the connecting material 8, so that the breaking assembly 3 can drive the connecting material 8 to move. The slider 31 is in contact with the side wall of the sliding cavity 112 in the sliding cavity 112 to limit the position, so that the slider 31 moves along the extension direction of the sliding cavity 112. At the beginning of the splitting, the slider 31 abuts against the bottom wall of the sliding cavity 112 away from the placement surface 111, and the end surface of the slider 31 away from the base 1 forms a material placement surface 312. When the spring sheet 7 is placed on the placement surface 111, the material 8 is also placed on the material placement surface 312. Then, the operator uses the pressing arm 23 and the placement surface 111 to press the spring sheet 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 sheet 7 and the material 8. Then, the operator 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 sheet 7, so that the connecting arm 82 breaks, and the material 8 and the spring sheet 7 are separated. 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 pressing the material 8.

[0068] Optionally, the second pressing block 32 and the slider 31 can be slidably connected by a guide rod or a slide rail, and the sliding direction is set at an angle with the placement surface 111, or the second pressing block 32 and the slider 31 are rotatably connected by a hinge or a rotating shaft, or the second pressing block 32 and the slider 31 are detachably set. 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 away from the slider 31, and relatively locks the second pressing block 32 and the slider 31 by a locking member such as a bolt or a buckle, thereby pressing the connecting material 8.

[0069] In this embodiment, the second pressing block 32 and the slider 31 are detachably connected by a second fixing bolt 35, the second pressing block 32 is provided with a second through hole 323, the slider 31 is provided with a second threaded hole 313, the second fixing bolt 35 passes through the second through hole 323, and is connected to the second threaded hole 313, so that the second pressing block 32 and the slider 31 enclose a limiting cavity 33. It can be understood that at least two groups of the second fixing bolt 35, the second through hole 323 and the second threaded hole 313 can be provided to improve the stability of the connection between the second pressing 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 , and the pulling member 34 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 to improve the convenience of the operator's operation and improve production efficiency.

[0072] Optionally, the puller 34 is in a rod or stick shape, one end of the puller 34 is connected to the slider 31, and the other end of the puller 34 extends 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 to hold.

[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 connecting material 8 to move.

[0074] Optionally, the puller 34 is an auxiliary bolt, and the slider 31 is provided with a mounting surface 314, and a threaded hole is 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 hold. The auxiliary bolt is connected to the middle position of the slider 31, so that when the operator pulls the puller 34, the slider 31 is balanced in force and moves smoothly. 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 is 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 passes through the first positioning hole 321 .

[0076] In this embodiment, if Figure 2 , Figure 7 and Fig. 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 limited in the first positioning hole 321 to achieve the positioning and placement of the connecting material 8 and the spring piece 7. Multiple groups of the first positioning pin 311, the positioning hole 83 and the first positioning hole 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 around 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 sliding block 31 passes through the avoidance groove 121 .

[0080] It is understandable 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, so that the operator can hold the puller 34. Therefore, the avoidance groove 121 provided on the base 1 is used to avoid the puller 34, so that the end of the puller 34 away from the slider 31 can extend out of the sliding cavity 112.

[0081] Optionally, the avoidance groove 121 is connected to the sliding cavity 112 and can be arranged 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 an avoidance groove for avoiding the pulling member 34, and a limiting surface 122 is formed on a side of the limiting portion 12 facing the sliding cavity 112. The limiting surface 122 is arranged parallel to a mounting surface 314 on which the pulling member 34 is mounted on the sliding block 31. When the sliding block 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] Understandable, such as Figure 1 and Figure 6 As shown, the main body 11 has two first side walls and two second side walls, and 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 connected to the placement surface 111 at an angle, and 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, and the two second side walls of the main body 11 are also arranged opposite to each other and connected to the first side walls and the placement surface 111 at an angle.

[0088] In this embodiment, when the travel of the slider 31 along the extension direction of the sliding cavity 112 is limited, the slider 31 cannot be directly inserted into the sliding cavity 112 through the cavity opening of the placement surface 111 from the sliding cavity 112. Therefore, the operator inserts the slider 31 into the sliding cavity 112 from the insertion port 13, which is provided on the second side wall and parallel to the extension direction of the sliding cavity 112. The cross-sectional size and shape of the insertion port 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 insertion port 13, or both of the two second side walls are provided with an insertion port 13. The puller 34 connected to the slider 31 may be provided in a handle shape, and when the slider 31 is placed in the sliding cavity 112, both ends of the puller 34 extend from the insertion port 13 into the sliding cavity 112 to connect with the slider 31. The slider 31 may partially extend or leak out of the sliding cavity 112 at the insertion port 13, so that the operator can withdraw the slider 31 from the insertion port 13 into the sliding cavity 112.

[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 escaping from the inlet 13 during the sliding process 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 inlet 13 to prevent the slider 31 from escaping from the inlet 13.

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

[0093] In this embodiment, the insertion opening 13 includes two, and the two insertion openings 13 are respectively arranged on the two second side walls of the main body 11. Correspondingly, the limiting members 5 also include two, and the main body 11 is provided with a through hole penetrating the two second side walls, and a connecting member 6 is passed through the through hole, and both ends of the connecting member 6 extend out of the through hole at the same time, and the two limiting members 5 are respectively connected to the two ends of the connecting member 6, and abut against the two side walls of the slider 31 facing the insertion opening 13, so as to limit the slider 31 in the sliding cavity 112. Optionally, the connecting member 6 can be a screw rod, and the limiting member 5 is threadedly connected to the screw rod, and the limiting member 5 can be set in a disc shape, so that the operator can rotate the limiting member 5 to connect the limiting member 5 to the screw rod or remove it from the screw rod.
