[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] Example 1

[0034] like Figure 1 , Figure 2 , Figure 4 As shown, the cable tie with a cut-off structure comprises:

[0035] The belt 10 has a tail end 12 and a head end 11, and the head end 11 is provided with a plurality of oblique teeth 112;

[0036] The housing 20 has a cavity 1 21 and a cavity 22 which are transversely connected thereto.

[0037] The cutting piece 40 includes a rod body 41 penetrating the side wall of the cavity 21, and a knife 45 and a bite tooth 46 are arranged at one end of the rod body 41 located inside the housing 20;

[0038] The head end 11 is inserted into the interior of cavity 1 21, and the tail end 12 is assembled in the interior of cavity 22. The rod body 1 41 has a stop position and a cutting position in the interior of cavity 1 21. When it is in the stop position, the oblique teeth 112 cooperate with the engaging teeth 46. When it is in the cutting position, the knife 45 contacts the head end 11 and cuts the head end 11.

[0039] In this technical solution, when it is necessary to bundle items, the head end 11 is inserted into the cavity 21 from the right side of the shell 20, and under the cooperation of the reaction force of the bundled items (the direction of the force is as shown in FIG. Figure 1 As shown by the arrow in the figure, the oblique teeth 112 cooperate with the engaging teeth 46, the relative positions of the head end 11 and the shell 20 are fixed, and the bundling of the items is completed; when disassembling, the rod body 41 is adjusted to the cutting position, and the knife 45 contacts the head end 11 and cuts the head end 11.

[0040] The cable tie with a cutting structure in the technical solution not only meets the need of bundling articles with the cable tie, but also has a cutting piece 40 that can conveniently and quickly cut the strap 10, so that the cable tie has a quick cutting function;

[0041] 1. Cable ties are highly safe when used. In an emergency, they can be quickly cut off to avoid damage to equipment or personnel;

[0042] 2. Prevent the cable tie from shrinking over time, becoming too tight and difficult to remove;

[0043] 3. Cable ties are easy to disassemble, making it more convenient to replace or adjust bundled items, such as cables and pipes.

[0044] like Figure 2 , Figure 3 , Figure 4 As shown, the shell 20 is provided with a hole three 23 that passes through the cavity one 21; a threaded section 411 is provided at one end of the rod body 41 located outside the cavity one 21, and the threaded section 411 is threadedly matched with an internal threaded sleeve 42, and a section of the rod body 41 located between the shell 20 and the internal threaded sleeve 42 is sleeved with a spring 43, and the internal threaded sleeve 42 is provided with a rod body two 44 that matches the hole three 23. The rod body two 44 can be set to one or more. When it is set to multiple, the distance between each two adjacent rod bodies two 44 is the same, and the number of holes three 23 is consistent with that of the rod body two 44.

[0045] When the rod body 41 is located in the stop position, the rod body 41 does not cooperate with the hole three 23, including two modes: 1. the rod body 41 is located above the hole three 23, but is not inserted into the inside of the hole three 23; 2. the rod body 41 is not located above the hole three 23. The second mode is adopted in this embodiment to avoid accidental touch and misoperation; when the rod body 41 is located in the cutting position, the rod body 41 cooperates with the hole three 23, that is, the rod body 41 is located above the hole three 23 and can be inserted into the hole three 23 for operation.

[0046] When the cable tie with a cutting structure in the present technical solution is cut, the internal threaded sleeve 42 is rotated on the threaded section 411 until the rod body 41 is located above the hole 3 23, and then the internal threaded sleeve 42 is pressed to drive the rod body 1 41, the rod body 2 44, the knife 45, and the bite tooth 46 to move downward, and the bite tooth 46 is inserted into the inside of the hole 111, and the knife 45 cuts the head end 11. At this time, the spring 43 is compressed. After the cutting is completed, under the action of the spring 43, the rod body 1 41, the internal threaded sleeve 42, the rod body 2 44, the knife 45, and the bite tooth 46 move upward and reset.

[0047] In the present technical solution, the spring 43 is provided to support the internal threaded sleeve 42, and the distance between the internal threaded sleeve 42 and the outer wall of the shell 20 is ensured, thereby ensuring that the fixed end of the knife 45 contacts the inner wall of the cavity 21; at the same time, the bevel teeth 112 contact the inner wall of the cavity 21 to ensure the distance between the head end 11 and the inner wall of the shell 20. The two cooperate with each other to ensure that when no cutting operation is performed, there is a gap between the knife 45 and the head end 11, thereby ensuring the bundling function of the belt 10.

[0048] To ensure the stability of the cable tie's anti-retraction function, Figure 2 As shown, a longitudinally penetrating hole 111 is provided on the head end 11, and the engaging teeth 46 are inserted into the hole 111 to increase the resistance of the head end 11 to move backward, thereby ensuring the stability of the cable tie's anti-retraction function.

[0049] like Figure 2 As shown, the tail end 12 is assembled inside the second cavity 22 through a fixing member 30 ; the fixing member 30 includes a screw 31 , and a threaded hole penetrating the second cavity 22 is provided on the housing 20 , and the thread in the threaded hole matches the screw 31 .

[0050] When the tail end 12 is assembled to the housing 20 , the tail end 12 is first inserted into the interior of the second cavity 22 , and the screw 31 is threadedly engaged with the threaded hole until the head end of the screw 31 engages with the side wall of the second cavity 22 to squeeze and fix the tail end 12 .

[0051] The cable tie with a cutting structure in the present technical solution has a detachable fit between the tail end 12 and the shell 20. After a strap 10 is cut and damaged, the shell 20 can be matched with a new strap 10 and continue to be put into use, thereby saving costs and reducing waste of resources.

[0052] like Figure 2 As shown, a second longitudinal hole 121 is provided on the tail end 12 , and a screw 31 is inserted into the second hole 121 to increase the resistance required for the movement of the tail end 12 and ensure the stability of the tail end 12 assembled inside the second cavity 22 .

[0053] To further improve the stability of the tail end 12 assembled inside the second cavity 22, as shown in FIG. Figure 2 As shown, a section of the screw 31 located inside the second cavity 22 is provided with a pressing plate 32;

[0054] When assembling the tail end 12, the screw 31 is threadedly matched with the threaded hole, and the head end of the screw 31 is inserted into the interior of the second hole 121 until the pressure plate 32 and the second cavity 22 cooperate to clamp and fix the tail end 12; by increasing the contact area between the tail end 12 and the second cavity 22 and the screw 31, the stability of the assembly of the tail end 12 is improved.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
