[0088] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0089] Please refer to Figure 1 The rope buckle in the prior art is composed of a first extruded component 101 and a second extruded component 102 with different structures. During processing, two different molds are required to process the first extruded component 101 and the second extruded component 102 respectively, which not only increases the mold cost but also makes the production process more complicated.

[0090] The following is a preferred embodiment of a mirror image cord lock provided by the present invention that can solve the above technical problems.

[0091] Please refer to Figure 2-Figure 6 The first preferred embodiment of the present invention provides a mirror image rope buckle, which includes two extrusion members 11 and a compression spring 12 that are relatively movably arranged. Each extrusion member 11 is provided with a slot 1121 and an extrusion hole 1112, and the extrusion member 11 includes an insert block 113, and the insert block 113 is movably inserted into the slot 1121 of the other extrusion member 11. The compression spring 12 is arranged between the two extrusion members 11. The relative positions of the two extrusion members 11 include an overlap position and a staggered position, and the resilience of the compression spring 12 makes the two extrusion members 11 have a tendency to move away from each other, and move from the overlap position to the staggered position. When the relative positions of the two extrusion members 11 are in the overlap position, the extrusion hole 1112 of one extrusion member 11 overlaps with the extrusion hole 1112 of the other extrusion member 11, allowing the rope to pass through. When the relative positions of the two extrusion members 11 are in the staggered position, the extrusion hole 1112 of one extrusion member 11 is staggered with the extrusion hole 1112 of the other extrusion member 11, thereby clamping the rope.

[0092] The mirror image cord buckle of the present invention is composed of two identical extruded parts 11, and only one mold is needed for processing, which can save mold opening costs and simplify the processing process.

[0093] Please refer to Figure 5There are two extrusion holes 1112 on the extrusion member 11. The two extrusion holes 1112 on one extrusion member 11 correspond to the two extrusion holes 1112 on the other extrusion member 11. The extrusion member 11 also includes a main board 111 and a side board 112. The two extrusion holes 1112 are both arranged on the main board 111. The main board 111 has two opposite and parallel connecting edges 1111 extending along the arrangement direction of the two extrusion holes 1112. The plug block 113 is connected to one connecting edge 1111, and the plug block 113 and the main board 111 are arranged side by side along the relative movement direction of the two extrusion members 11. The side board 112 is connected to the other connecting edge 1111, and the side board 112 and the main board 111 are perpendicular to each other. The slot 1121 is arranged on the side board 112. The two ends of the compression spring 12 are respectively in contact with the two side boards 112, and the compression spring 12 is located between the two main boards 111. In the above structure, the extrusion member 11 is mainly composed of a side plate 112, a main plate 111 and an insert block 113 which are connected in sequence, and has a simple structure and is easy to process. There are two extrusion holes 1112 on the extrusion member 11, and two ropes can be respectively inserted into the two groups of extrusion holes 1112, which is more convenient for the ropes to pass through. In other embodiments, an extrusion hole 1112 can also be set on the main plate 111, and two ropes can be inserted into one extrusion hole 1112 at the same time. The insert block 113 and the main plate 111 are arranged side by side along the relative movement direction of the two extrusion members 11, so that the relative movement of the two extrusion members 11 is stable and easy to process.

[0094] Please refer to Figure 5 , the plug block 113 is in the shape of a plate, and the main board 111, the side board 112, the plug block 113 and the slot 1121 are all in the shape of strips arranged along the arrangement direction of the two extrusion holes 1112. In the direction perpendicular to the relative movement of the two extrusion members 11, at least one edge of the main board 111 protrudes from the plug block 113 and forms an abutment portion 1113. When the relative positions of the two extrusion members 11 are in the overlap position, the abutment portion 1113 of one extrusion member 11 abuts against the side board 112 of the other extrusion member 11. In the above structure, the main board 111 is in the shape of a strip, and its length direction is consistent with the arrangement direction of the two extrusion holes 1112, so that the two extrusion holes 1112 can maintain a proper distance between them, and when the two ropes are respectively inserted into the two groups of extrusion holes 1112, they do not interfere with each other. During use, the relative positions of the two extrusion members 11 are in the overlap position by pressing the two side boards 112, and the long strip shape of the side boards 112 is more conducive to pressing. The insert block 113 is plate-shaped, and the insert block 113 and the slot 1121 are both strip-shaped and arranged along the arrangement direction of the two extrusion holes 1112. With this structure, the extrusion piece 11 can maintain balance and move stably during movement. The abutment portion 1113 can accurately align the extrusion holes 1112, making it easy to adjust the two extrusion pieces 11 to the overlapping position.

[0095] Please refer to Figure 6, a strip-shaped limiting structure 1131 is provided on the plug block 113, which is parallel to the slot 1121, and the outer long side of the limiting structure 1131 is flush with the outer long side of the plug block 113, and the limiting structure 1131 is used to limit and abut against the side plate 112 of another extrusion piece 11. In the thickness direction of the main board 111, the size of the limiting structure 1131 gradually increases from the side far away from the main board 111 to the side close to the main board 111. When there is no rope in the extrusion hole 1112, the limiting structure 1131 can prevent the two extrusion pieces 11 from detaching, which is convenient to use. When the limiting structure 1131 is in limit and abut against the side plate 112 of another extrusion piece 11, the limiting structure 1131 is in a strip shape, which can keep the two extrusion pieces 11 balanced. When the plug block 113 is inserted into the slot 1121, the size of the limiting structure 1131 gradually increases from the side away from the main board 111 to the side close to the main board 111 in the thickness direction of the main board 111, so that the limiting structure 1131 can pass through the slot 1121 easily without being easily disengaged. The outer long side of the limiting structure 1131 is flush with the outer long side of the plug block 113. In the case of a limited width of the plug block 113, the relative movement of the two extrusion members 11 is larger. When the two extrusion members 11 are in a staggered position, the overlapping space formed by the two extrusion holes 1112 is smaller to accommodate a thinner rope.

[0096] Please refer to Figure 4 and Figure 5 A positioning column 1122 is provided in the middle of the side plate 112. The positioning columns 1122 of the two extrusion members 11 are coaxial and spaced apart. The two ends of the compression spring 12 are respectively sleeved on the two positioning columns 1122. With the above structure, the compression spring 12 is fixed and stable, and the two positioning columns 1122 are spaced apart, which will not affect the limiting abutment between the abutment portion 1113 and the side plate 112. The positioning column 1122 is located in the middle of the length direction of the side plate 112, so that the compression spring 12 is located between the two ropes to avoid mutual interference.

[0097] In this embodiment, the structural layout of each part of the extruded part 11 facilitates injection molding and mold design, is conducive to mold opening, and can reduce production and preparation costs.

[0098] The method for using the mirror image cord lock according to the first preferred embodiment of the present invention is as follows:

[0099] 1. Place two extrusion members 11 opposite to each other, and sleeve one end of the compression spring 12 onto one of the positioning posts 1122;

[0100] 2. Insert the insert block 113 into the slot 1121 of another extrusion piece 11, and prevent the insert block 113 from being separated from the slot 1121 by the limiting structure 1131; and sleeve the other end of the compression spring 12 onto the positioning column 1122 of another extrusion piece 11;

[0101] 3. Press the two side plates 112 to make the abutting portion 1113 of one extrusion member 11 abut against the side plate 112 of the other extrusion member 11. At this time, the relative positions of the two extrusion members 11 are in the overlapped position, and the extrusion holes 1112 of one extrusion member 11 overlap with the extrusion holes 1112 of the other extrusion member 11. Pass the two ropes through the two groups of extrusion holes 1112 respectively.

[0102] 4. Loosen the two side plates 112, and the resilience of the compression spring 12 causes the relative positions of the two extrusion members 11 to be offset. At this time, the extrusion hole 1112 of one extrusion member 11 is offset from the extrusion hole 1112 of the other extrusion member 11, thereby clamping the rope.

[0103] The above is the method of using the mirror image cord lock according to the first preferred embodiment.

[0104] Please refer to Figure 7 , Figure 8 and Fig. 9 The second preferred embodiment of the present invention provides a mirror image rope buckle, which includes two extrusion members 21 and a compression spring 22 that are relatively movably arranged. Each extrusion member 21 is provided with a slot 213 and an extrusion hole 216. The extrusion member 21 includes an insert block 214, which is movably inserted into the slot 213 of the other extrusion member 21. The compression spring 22 is arranged between the two extrusion members 21. The relative positions of the two extrusion members 21 include an overlap position and a staggered position. The resilience of the compression spring 22 makes the two extrusion members 21 have a tendency to move away from each other and move from the overlap position to the staggered position. When the relative positions of the two extrusion members 21 are in the overlap position, the extrusion hole 216 of one extrusion member 21 overlaps with the extrusion hole 216 of the other extrusion member 21 for the rope to pass through. When the relative positions of the two extrusion members 21 are in the staggered position, the extrusion hole 216 of one extrusion member 21 is staggered with the extrusion hole 216 of the other extrusion member 21, thereby clamping the rope.

[0105] The mirror image cord buckle of the present invention is composed of two identical extruded parts 21, and only one mold is needed for processing, which can save mold opening costs and simplify the processing process.

[0106] Please refer to Fig. 9, the extrusion holes 216 on each extrusion member 21 include two first extrusion outer holes 2121 and a first extrusion inner hole 2141. The extrusion member 21 also includes a connecting plate 211, two clamping arms 212, and an insert block 214. The two clamping arms 212 are both plate-shaped, and the two clamping arms 212 are connected to one end of the connecting plate 211. A slot 213 is formed between the two clamping arms 212. The two first extrusion outer holes 2121 are respectively arranged on the two clamping arms 212, and the two first extrusion outer holes 2121 are coaxially arranged. The insert block 214 is plate-shaped and connected to the other end of the connecting plate 211. The insert block 214 is arranged in parallel with the two clamping arms 212, and the three protrude from the same side of the connecting plate 211. The first extrusion inner hole 2141 is arranged on the insert block 214. When the relative positions of the two extrusion members 21 are in the overlapped position, the two first extrusion outer holes 2121 of one extrusion member 21 overlap with the first extrusion inner hole 2141 of the other extrusion member 21; when the relative positions of the two extrusion members 21 are in the offset position, the two first extrusion outer holes 2121 of one extrusion member 21 are offset with the first extrusion inner hole 2141 of the other extrusion member 21. In the above structure, a slot 213 is formed between the two clamp arms 212. When assembling, it is only necessary to insert the insert block 214 into the slot 213 of the other extrusion member 21 so that the two extrusion outer holes of one extrusion member 21 correspond to the extrusion inner hole of the other extrusion member 21, and fix the compression spring 22 between the two connecting plates 211. The assembly process is simple.

[0107] The plug block 214 and the two clamp arms 212 are both plate-shaped and arranged in parallel. The plug block 214 and the clamp arms 212 are respectively fixed to the two ends of the connecting plate 211. This structure allows the extrusion part 21 to be conveniently formed as one piece through an injection molding process, ensuring that the overall structural strength of the extrusion part 21 is better, and is convenient for mold design, mold opening, and can reduce production and preparation costs.

[0108] Please continue to refer to Fig. 9 The extrusion piece 21 also includes a limiting column 215, which is arranged on the same side of the connecting plate 211 as the plug block 214. The limiting columns 215 of the two extrusion pieces 21 are coaxially arranged, and the two ends of the compression spring 22 are respectively sleeved on the two limiting columns 215. When the relative positions of the two extrusion pieces 21 are in the overlapped position, the two limiting columns 215 abut against each other. With the above structure, the compression spring 22 is fixed and stable, and the two extrusion outer holes of one extrusion piece 21 can also be accurately aligned with the extrusion inner hole of the other extrusion piece 21, so that the two extrusion pieces 21 can be adjusted to the overlapped position.

[0109] Please continue to refer to Fig. 9, two clamp arms 212 and plug block 214, all of which are square and of the same size, and are perpendicular to the connecting plate 211. The slot 213 is open at the four sides of the clamp arm 212, and the slot 213 and the plug block 214 are transitionally matched. With this structure, it is convenient to accurately assemble the two extrusions 21. When the compression spring 22 rebounds, the two clamp arms 212 and the plug block 214 of the other extrusion 21 can overlap, indicating that the assembly is accurate in the direction perpendicular to the movement of the extrusion 21. During installation, align the two sides of the plug block 214 in the same moving direction as the extrusion 21 with the corresponding sides of the two clamp arms 212 of the other extrusion 21, and the plug block 214 can be accurately inserted into the slot 213 of the other extrusion 21, which is convenient for assembly. The slot 213 is open at the four sides of the clamp arm 212, which is convenient for processing, and can reduce the weight of the extrusion 21 and save materials. The slot 213 and the insert block 214 are in transitional fit, so that the two extrusion members 21 are inserted stably.

[0110] Please continue to refer to Fig. 9 The side surface of the connecting plate 211 away from the clamping arm 212 is located in the same plane as the edges of the two clamping arms 212 and the edge of the inserting block 214. This structure makes the mirror-image cord buckle more regular all around and will not interfere with the user.

[0111] Please continue to refer to Fig. 9 The connecting plate 211 is long and has a length 1.5-2.5 times the diameter of the first extrusion outer hole 2121. The clamping arm 212 and the plug block 214 are respectively placed at both ends of the length direction of the connecting plate 211. When in use, the two extrusion members 21 are placed in an overlapping position by squeezing the two connecting plates 211. The above structure is convenient for the user to press.

[0112] The two first extrusion outer holes 2121 and the first extrusion inner hole 2141 are both circular. This structure can facilitate most ropes to pass through, and has strong versatility.

[0113] In this embodiment, the structural layout of each part in the extrusion part 21 is convenient for injection molding and mold design, which is conducive to mold opening and can reduce production and preparation costs.

[0114] The method for using the mirror image cord lock according to the second preferred embodiment of the present invention is as follows:

[0115] 1. Place two extrusion members 21 opposite to each other, and sleeve one end of the compression spring 22 onto one of the limit posts 215;

[0116] 2. Insert the insert block 214 into the slot 213 of the other extrusion piece 21, and sleeve the other end of the compression spring 22 onto the limiting column 215 of the other extrusion piece 21;

[0117] 3. Press the two connecting plates 211 so that the relative positions of the two extrusion members 21 are in the overlapped position. At this time, the two first extrusion outer holes 2121 of one extrusion member 21 overlap with the first extrusion inner holes 2141 of the other extrusion member 21, and pass the two ropes through the two groups of first extrusion outer holes 2121 respectively;

[0118] 4. Loosen the two connecting plates 211, and the resilience of the compression spring 22 causes the relative positions of the two extrusion members 21 to be offset. At this time, the two first extrusion outer holes 2121 of one extrusion member 21 are offset from the first extrusion inner holes 2141 of the other extrusion member 21, thereby clamping the rope.

[0119] The above is the method of using the mirror image cord lock according to the second preferred embodiment.

[0120] Please refer to Figure 10-13 The third preferred embodiment of the present invention provides a mirror image rope buckle, which includes two extrusion members 31 and a compression spring 32 that are relatively movably arranged. Each extrusion member 31 is provided with a slot 3112 and an extrusion hole 314. The extrusion member 31 includes an insert block 313, which is movably inserted into the slot 3112 of the other extrusion member 31. The compression spring 32 is arranged between the two extrusion members 31. The relative positions of the two extrusion members 31 include an overlap position and a staggered position. The resilience of the compression spring 32 makes the two extrusion members 31 have a tendency to move away from each other and move from the overlap position to the staggered position. When the relative positions of the two extrusion members 31 are in the overlap position, the extrusion hole 314 of one extrusion member 31 overlaps with the extrusion hole 314 of the other extrusion member 31 for the rope to pass through. When the relative positions of the two extrusion members 31 are in the staggered position, the extrusion hole 314 of one extrusion member 31 is staggered with the extrusion hole 314 of the other extrusion member 31, thereby clamping the rope.

[0121] The mirror image cord buckle of the present invention is composed of two identical extruded parts 31, and only one mold is needed for processing, which can save mold opening costs and simplify the processing process.

[0122] Please refer to Fig.12 and Fig.13There are two compression springs 32, and the extrusion holes 314 on each extrusion member 31 include two second extrusion outer holes 3111 and a second extrusion inner hole 3131. Each extrusion member 31 also includes a receiving tube 311, an end plate 312 and an insert block 313. The two second extrusion outer holes 3111 are arranged on the side wall of the receiving tube 311, and the two second extrusion outer holes 3111 are coaxially arranged, and the inner cavity of the receiving tube 311 forms a slot 3112. The end plate 312 is fixed to one end of the receiving tube 311. The insert block 313 protrudes from the other end of the receiving tube 311, and the second extrusion inner hole 3131 is arranged on the insert block 313. The two ends of the compression spring 32 are respectively in contact with the end plate 312 of one extrusion member 31 and the insert block 313 of the other extrusion member 31. When the relative positions of the two extrusion parts 31 are in the overlapping position, the two second extrusion outer holes 3111 of one extrusion part 31 overlap with the second extrusion inner hole 3131 of the other extrusion part 31; when the relative positions of the two extrusion parts 31 are in the staggered position, the two second extrusion outer holes 3111 of one extrusion part 31 are staggered with the second extrusion inner hole 3131 of the other extrusion part 31.

[0123] In the above structure, the inner cavity of the accommodating cylinder 311 forms a slot 3112, and the insert block 313 of one extrusion member 31 is movably inserted into the slot 3112 of another extrusion member 31, thereby realizing the movable connection of the two extrusion members 31, and the structure is stable.

[0124] Please refer to Fig.13 , the plug block 313 extends into the inner cavity of the receiving tube 311, the side of the plug block 313 is connected to the inner wall of the receiving tube 311, and the end face of the plug block 313 is connected to the end plate 312; the receiving tube 311 is cylindrical, the plug block 313 is semi-cylindrical, and the plug block 313 is transitionally matched with the slot 3112 of another extrusion member 31. In the above structure, the plug block 313 is connected to the end plate 312, so that the plug block 313 is firmly connected to the receiving tube 311, and the semi-cylindrical plug block 313 can fill half of the space in the receiving tube 311, so that the slot 3112 in the receiving tube 311 is also formed into a semi-cylindrical shape, which is conducive to the matching of the plug block 313 and the slot 3112, and is easy to process. The plug block 313 is transitionally matched with the slot 3112 of another extrusion member 31, so that the two extrusion members 31 are stably plugged and not easily separated when there is no rope.

[0125] Please refer to Fig.10 When the relative positions of the two extrusion members 31 are at the overlapped position, the other ends of the two accommodating tubes 311 abut against each other. This structure facilitates the adjustment of the two extrusion members 31 to the overlapped position.

[0126] Please refer to Fig.12 The second extrusion outer hole 3111 and the second extrusion inner hole 3131 are both circular. This structure can facilitate most ropes to pass through, and has strong versatility.

[0127] In this embodiment, the structural layout of each part in the extrusion part 31 is convenient for injection molding and mold design, which is conducive to mold opening and can reduce production and preparation costs.

[0128] The method for using the mirror image cord lock according to the third preferred embodiment of the present invention is as follows:

[0129] 1. Place two extrusion members 31 opposite to each other and place the compression springs 32 in the two slots 3112 respectively;

[0130] 2. Insert the insert block 313 into the slot 3112 of another extrusion member 31;

[0131] 3. Press the two end plates 312 so that the other ends of the two accommodating tubes 311 abut against each other. At this time, the relative positions of the two extrusion members 31 are in an overlapping position. The two second extrusion outer holes 3111 of one extrusion member 31 overlap with the second extrusion inner holes 3131 of the other extrusion member 31. Pass the two ropes through the two sets of second extrusion outer holes 3111 respectively.

[0132] 4. Loosen the two end plates 312. The resilience of the compression spring 32 causes the relative positions of the two extrusion members 31 to be offset. At this time, the two second extrusion outer holes 3111 of one extrusion member 31 are offset from the second extrusion inner holes 3131 of the other extrusion member 31, thereby clamping the rope.

[0133] The above is the method of using the mirror image cord lock according to the third preferred embodiment.

[0134] Please refer to Figure 14-17 The fourth preferred embodiment of the present invention provides a mirror image rope buckle, which includes two extrusion members 41 and a compression spring 42 that are relatively movably arranged. Each extrusion member 41 is provided with a slot 4112 and an extrusion hole 415, and the extrusion member 41 includes an insert block 413, and the insert block 413 is movably inserted in the slot 4112 of the other extrusion member 41. The compression spring 42 is arranged between the two extrusion members 41. The relative positions of the two extrusion members 41 include an overlap position and a staggered position. The resilience of the compression spring 42 makes the two extrusion members 41 have a tendency to move away from each other and move from the overlap position to the staggered position. When the relative positions of the two extrusion members 41 are in the overlap position, the extrusion hole 415 of one extrusion member 41 overlaps with the extrusion hole 415 of the other extrusion member 41 for the rope to pass through. When the relative positions of the two extrusion members 41 are in the staggered position, the extrusion hole 415 of one extrusion member 41 is staggered with the extrusion hole 415 of the other extrusion member 41, thereby clamping the rope.

[0135] The mirror image cord buckle of the present invention is composed of two identical extruded parts 41, and only one mold is needed for processing, which can save mold opening costs and simplify the processing process.

[0136] Please refer to Fig.16 There are two compression springs 42, and the extrusion hole 415 on each extrusion member 41 includes two second extrusion outer holes 4111 and a second extrusion inner hole 4131. Each extrusion member 41 also includes a receiving tube 411, an end plate 412 and an insert block 413. The two second extrusion outer holes 4111 are arranged on the side wall of the receiving tube 411, and the two second extrusion outer holes 4111 are coaxially arranged, and the inner cavity of the receiving tube 411 forms a slot 4112. The end plate 412 is fixed to one end of the receiving tube 411. The insert block 413 protrudes from the other end of the receiving tube 411, and the second extrusion inner hole 4131 is arranged on the insert block 413. The two ends of the compression spring 42 are respectively in contact with the end plate 412 of one extrusion member 41 and the insert block 413 of the other extrusion member 41. When the relative positions of the two extrusion parts 41 are in the overlapping position, the two second extrusion outer holes 4111 of one extrusion part 41 overlap with the second extrusion inner hole 4131 of the other extrusion part 41; when the relative positions of the two extrusion parts 41 are in the staggered position, the two second extrusion outer holes 4111 of one extrusion part 41 are staggered with the second extrusion inner hole 4131 of the other extrusion part 41.

[0137] In the above structure, the inner cavity of the accommodating cylinder 411 forms a slot 4112, and the insert block 413 of one extrusion component 41 is movably inserted into the slot 4112 of another extrusion component 41, thereby realizing the movable connection of the two extrusion components 41, and the structure is stable.

[0138] Please refer to Fig.16 and Fig.17 The accommodating cylinder 411 is square and includes two opposite first walls 4113 and two opposite second walls 4114. The two second extrusion outer holes 4111 are respectively arranged on the two first walls 4113. The second wall 4114 is provided with a limiting strip 4116 protruding toward the other second wall 4114, and the two limiting strips 4116 are arranged at intervals. The two limiting strips 4116 and the first wall 4113 away from the plug block 413 form a slot 4112. The plug block 413 is long and strip-shaped, and it transitionally matches with the slot 4112 of the other extrusion member 41. The insert block 413 is also provided with an anti-drop block 4132, which is located on the side of the second extrusion inner hole 4131 away from the accommodating cylinder 411. When the two extrusion members 41 move in a direction away from each other, the anti-drop block 4132 is used to limit and abut against the hole wall of the second extrusion outer hole 4111 of the other extrusion member 41. The side of the anti-drop block 4132 away from the accommodating cylinder 411 is an inclined surface for facilitating the introduction of the insertion slot 4112. A avoidance groove 4115 is provided on the side of the second extrusion outer hole 4111 close to the end plate 412. The avoidance groove 4115 is connected to the extrusion outer hole, and the avoidance groove 4115 is used to avoid the anti-drop block 4132.

[0139] The above structure not only makes the two extrusion members 41 stable when plugged in, but also when the extrusion member 41 needs to be set to a larger size, the plug block 413 can be thinner and the corresponding size of the slot 4112 can be smaller, thereby saving materials and reducing the weight of the mirror image rope buckle. When there is no rope in the two sets of second extrusion outer holes 4111, the anti-slip block 4132 can prevent the two extrusion members 41 from detaching, which is convenient for use. One side of the anti-slip block 4132 is an inclined surface, which is convenient for the anti-slip block 4132 to be inserted into the slot 4112, and at the same time will not affect the anti-slip block 4132 and the hole wall of the second extrusion outer hole 4111. The avoidance groove 4115 can prevent the anti-slip block 4132 from getting stuck with the first wall 4113, so that the two extrusion members 41 can move smoothly to the overlapping position.

[0140] Please refer to Fig.17 The extrusion member 41 further includes a boss 414, which is disposed on the inner side of the end plate 412, and the two compression springs 42 are sleeved on the two bosses 414 in a one-to-one correspondence. With the above structure, the compression springs 42 are fixed and stable.

[0141] In this embodiment, the structural layout of each part of the extruded part 41 is convenient for injection molding and mold design, which is conducive to mold opening and can reduce production and preparation costs.

[0142] The method for using the mirror image cord lock according to the fourth preferred embodiment of the present invention is as follows:

[0143] 1. Place two extrusion members 41 opposite to each other, and sleeve the two ends of the compression spring 42 onto the two protruding pillars 414 respectively;

[0144] 2. Insert the insert block 413 into the slot 4112 of another extrusion member 41;

[0145] 3. Press the two end plates 412 so that the relative positions of the two extrusion members 41 are in the overlapped position, and the anti-dropping block 4132 is located in the avoidance groove 4115. At this time, the two second extrusion outer holes 4111 of one extrusion member 41 overlap with the second extrusion inner holes 4131 of the other extrusion member 41, and pass the two ropes through the two groups of second extrusion outer holes 4111 respectively;

[0146] 4. Loosen the two end plates 412. The resilience of the compression spring 42 causes the relative positions of the two extrusion members 41 to be offset. At this time, the two second extrusion outer holes 4111 of one extrusion member 41 are offset from the second extrusion inner holes 4131 of the other extrusion member 41, thereby clamping the rope.

[0147] The above is the method of using the mirror image cord lock according to the fourth preferred embodiment.

[0148] The mirror image cord buckle of the present invention is composed of two identical extruded parts and only requires one mold during processing, which can save mold opening costs and simplify the processing process.

[0149] To sum up, although the present invention has been disclosed as above in the form of preferred embodiments, the protection scope of the present invention is not limited thereto, and any technician familiar with the technical field can make equivalent substitutions or changes according to the concept of the technical solution of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
