[0026] Refer Figures 1 to 6 As shown, a staple tie includes a tie 1, a buckle 2, and a staple 3 arranged in sequence. A locking tooth 11 is arranged on one end face of the tie 1. A slot 21 is arranged in the buckle 2. A locking tongue 211 corresponding to the locking tooth 11 is arranged on the inner wall of the slot 21. Two groups of symmetrically distributed long-axis leaf tooth groups are arranged on the surface of the staple 3. Each long-axis leaf tooth group includes a plurality of long-axis leaf teeth 31 arranged along the axial direction of the staple 3 in sequence. Among them, a long-axis thickening portion 311 is arranged on the long-axis leaf tooth 31 at the end away from the buckle 2.

[0027] In this technical solution, the cable tie, the lock, the card slot and the tongue can all adopt the structures described in the existing technology. The staple is of a columnar structure, and its cross-section is a conventional shape such as a circle or an ellipse. The side of the cable tie with teeth is the front side, and on the opposite side, first reinforcing ribs protrude from both sides respectively to improve the overall strength of the cable tie. A groove corresponding to the first reinforcing rib is recessed on the inner wall of the card slot to ensure the cooperation between the cable tie and the lock. When the cross-section of the staple is an ellipse, long-axis leaf teeth groups are respectively arranged at both ends of the long axis. Each long-axis leaf teeth group includes four arc-shaped long-axis leaf teeth, and the adjacent long-axis leaf teeth are arranged at intervals. A long-axis thickening part is arranged on the outer wall of the long-axis leaf teeth at the starting end (the end of the staple away from the lock), increasing the force required to pull out the staple and improving the reliability and stability of the overall installation.

[0028] Exemplarily, referring to Figures 1 to 3 and Figure 6 As shown, from the end away from the lock 2 to the end close to the lock 2, the opening angles between several long-axis leaf teeth 31 in the same long-axis leaf teeth group and the staple 3 gradually increase.

[0029] In this technical solution, during the process of pulling out the staple from the installation hole, the two long-axis leaf teeth at the end (the end close to the lock) are first deformed by force, and in the continuous pulling-out process, they contact the adjacent long-axis leaf teeth, increasing the pulling-out resistance. The subsequent long-axis leaf teeth provide pulling-out resistance for the staple according to this rule, further increasing the pulling-out resistance of the staple.

[0030] Exemplarily, referring to Figure 6 As shown, the long-axis leaf teeth 31 and the staple 3 are integrally formed.

[0031] In this technical solution, the long-axis leaf teeth and the staple are integrally formed by processes such as injection molding, ensuring the connection strength between the long-axis leaf teeth and the staple.

[0032] Exemplarily, referring to Figures 1 to 5 As shown, two groups of symmetrically distributed short-axis leaf teeth groups are further arranged on the surface of the staple 3. The short-axis leaf teeth groups and the long-axis leaf teeth groups are arranged staggeredly in the circumferential direction of the staple 3.

[0033] In this technical solution, short-axis leaf teeth groups are respectively arranged at both ends of the short axis of the staple, without interfering with each other. Second reinforcing ribs are arranged on the surface of the staple along its axial direction to improve the strength of the staple. The second reinforcing ribs are arranged between the adjacent long-axis leaf teeth groups and short-axis leaf teeth groups, without interfering with the normal use of the long-axis leaf teeth groups and short-axis leaf teeth groups.

[0034] Exemplarily, referring to Figures 1 to 4 As shown, each short-axis leaf teeth group includes several short-axis leaf teeth 32 arranged in sequence along the axial direction of the staple 3. Among them, a short-axis thickening part 321 is arranged on the short-axis leaf teeth 32 at the end away from the lock 2.

[0035] In this technical solution, each group of short-axis blade teeth includes four short-axis blade teeth, and adjacent short-axis blade teeth are arranged at intervals. The outer wall of the short-axis blade teeth at the starting end (the end of the staple facing away from the lock buckle) is provided with a short-axis thickened portion to increase the force required to pull out the staple and improve the reliability and stability of the overall installation.

[0036] For example, see Figures 1 to 6 As shown, the short-axis blade teeth 32 and the adjacent long-axis blade teeth 31 are staggered along the axial direction of the staple 3 .

[0037] In this technical solution, during the process of pulling the staple out of the mounting hole, the two long-axis leaf teeth at the end are first deformed by force, and the deformation continues until the two short-axis leaf teeth at the end begin to deform by force, at which time the pull-out resistance increases. As the pull-out continues, the long-axis leaf teeth at the end are respectively in contact with the adjacent long-axis leaf teeth, at which time the pull-out resistance further increases. During the continued pull-out process, the short-axis leaf teeth at the end are respectively in contact with the adjacent short-axis leaf teeth, at which time the pull-out force further increases. The subsequent long-axis leaf teeth and short-axis leaf teeth provide pull-out resistance for the pull-out of the staple according to this rule. When the long-axis leaf teeth and short-axis leaf teeth at the starting end enter the deformation stage, the pull-out force will reach the maximum value, and the long-axis leaf teeth and short-axis leaf teeth at the starting end are respectively provided with corresponding long-axis thickened portions and short-axis thickened portions, so that the pull-out resistance is further improved.

[0038] For example, see Figure 4 As shown, the short-shaft blade teeth 32 are integrally formed with the staple 3 .

[0039] In this technical solution, the short-shaft blade teeth and the staples are integrally formed through injection molding and other processes to ensure the connection strength between the short-shaft blade teeth and the staples.

[0040] Exemplarily, a support plate 4 is provided between the lock buckle 2 and the staple 3 .

[0041] In this technical solution, the support plate is a conical structure, and a third reinforcing rib and a fourth reinforcing rib are respectively arranged between the lock and the staple. The third reinforcing rib and the fourth reinforcing rib are conventional structures and do not interfere with the normal use of the lock and the staple. The support plate and the fixed surface of the vehicle body are in abutment contact.

[0042] For example, see Figures 1 to 6 As shown, the cable tie 1, the lock buckle 2, the staple 3 and the support plate are integrally formed.

[0043] In this technical solution, cable ties, lock buckles, staples and support plates are integrally formed through injection molding and other processes, which simplifies the product structure, makes the product lightweight, and reduces mold opening and manufacturing costs.

[0044] Exemplarily, the lock buckle 2, the staple 3 and the support plate are integrally formed and are separately arranged with the cable tie.

[0045] In this technical solution, the buckle, the staple and the support plate are integrally formed by processes such as injection molding and are used in combination with the existing cable tie. The whole of the buckle, the staple and the support plate can be pre-installed at the corresponding position of the vehicle body. The tongue in the buckle is removed, and the cable tie can directly use the existing cable tie with a locking member and is used in combination during the wiring process, that is, the cable tie is connected to the staple through the buckle before bundling. The tongue in the buckle can also be retained to avoid mutual sliding between the cable tie and the buckle and reduce wear and the like.

[0046] To sum up, the staple cable tie has a simple structure, realizes product lightweight, reduces the mold opening and manufacturing costs. During the pulling-out process, the long-axis leaf teeth group and the short-axis leaf teeth group deform layer by layer, and the pulling-out force gradually increases. The overall pulling-out force increases in a stepless and progressive manner, and the performance is more stable and reliable; the long-axis leaf teeth and the short-axis leaf teeth at the starting end are both thickened, and the thickness after the leaf teeth are deformed and the thickening area are superimposed to be larger than the installation hole, so that the upper limit of the pulling-out force is further improved.

[0047] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0048] The above are only the specific implementation manners of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
