[0036] Please see Figure 1 and Figure 2 This utility model provides a paracord clamping device, comprising: a moving mechanism 10, including a moving end that moves in a straight line; a clamping mechanism 20, including a mounting base connected to the moving end, and a first clamp 24 and a second clamp 25 movably disposed on the mounting base, wherein a positioning gap for clamping the paracord is formed between the first clamp 24 and the second clamp 25; and a driving mechanism 30, which is drively connected to the first clamp 24 and / or the second clamp 25, driving the first clamp 24 and the second clamp 25 to move closer or further apart to change the size of the positioning gap; wherein the parts of the first clamp 24 and the second clamp 25 used for clamping the paracord are made of rubber. Preferably, the parts of the first clamp 24 and the second clamp 25 used for clamping the paracord are made of neoprene rubber.

[0037] In some embodiments, initially, the moving end of the moving mechanism 10 is in the starting position, and the positioning gap of the clamping mechanism 20 is at its maximum, facilitating the insertion of the paracord. After the drive mechanism 30 is activated, the first clamp 24 and the second clamp 25 move closer together, reducing the positioning gap and stably clamping the paracord. Simultaneously, the moving mechanism 10 drives the moving end to move in a straight line, and the clamping mechanism 20 subsequently transfers the paracord from its current position to the target position. Upon arrival, the drive mechanism 30 drives the first clamp 24 and the second clamp 25 to move in opposite directions, increasing the positioning gap and releasing the paracord. The entire process achieves automatic clamping and precise movement of the paracord, reducing manual intervention and improving production efficiency and quality.

[0038] It should be explained that, due to their weaving methods, Vectran braided ropes, ultra-high molecular weight polyethylene braided ropes, and aramid braided ropes all have hollow structures. This characteristic of the weaving structure means that it can only withstand radial tension and cannot withstand forces in other directions. This results in the following: when attempting to clamp the rope through the side, the paracord experiences a normal pressure perpendicular to the sidewall, leading to significant deformation. As the normal pressure increases, due to its hollow interior, the paracord cannot maintain a circular shape and gradually flattens, its cross-section changing from circular to flat. Therefore, the clamping mechanism 20 should be able to adapt to the deformation of the paracord under pressure and operate reliably under these conditions, always maintaining a stable clamp. That is, the clamping end in the clamping mechanism 20 that directly contacts the paracord should have a certain degree of elasticity, increasing the contact area with the paracord while preventing damage to the paracord. In this embodiment, the parts of the first clamp 24 and the second clamp 25 used to clamp the paracord are made of rubber. Rubber has good elasticity, a high coefficient of friction, and is not easy to damage the surface of the paracord. This ensures that the paracord will not slip or be damaged during the clamping process, effectively protecting the quality of the paracord.

[0039] Please see Figure 6 and Figure 8 In some embodiments, the first clamp 24 includes a first connector 241 and a first rubber member 242, the first rubber member 242 being sleeved on the outer side of one end of the first connector 241; the second clamp 25 includes a second connector and a second rubber member, the second rubber member being sleeved on the outer side of one end of the second connector; a positioning gap is formed between the first rubber member 242 and the second rubber member.

[0040] Please see Figures 3 to 7Furthermore, the mounting base includes a first guide plate 21 and a second guide plate 22, with the first guide plate 21 and the second guide plate 22 being movably connected; one of the first guide plate 21 and the second guide plate 22 is fixed relative to the moving end, and the other is connected to the drive mechanism 30; the first guide plate 21 is provided with a first guide groove 211, and the second guide plate 22 is provided with a second guide groove 221 and a third guide groove 222, with the central axes of the second guide groove 221 and the third guide groove 222 intersecting; a first clamp 24 is slidably inserted through the first guide groove 211 and the second guide groove 221, and a second clamp 25 is slidably inserted through the first guide groove 211 and the third guide groove 222.

[0041] Understandably, when the drive mechanism 30 operates, the first guide plate 21 or the second guide plate 22, which is connected to the drive mechanism 30, begins to move. The relative movement of the first guide plate 21 and the second guide plate 22 will cause the first chuck 24 and the second chuck 25 to slide within the second guide groove 221 and the third guide groove 222, respectively. As the first guide plate 21 and the second guide plate 22 move relative to each other, the first chuck 24 slides along the first guide groove 211 and the second guide groove 221, while the second chuck 25 slides along the first guide groove 211 and the third guide groove 222. Since the central axes of the second and third guide grooves 222 intersect, the first chuck 24 and the second chuck 25 will gradually move closer or further apart during the sliding process, thereby changing the size of the positioning gap and realizing the clamping or loosening action of the paracord. During this process, the first guide groove 211, the second guide groove 221, and the third guide groove 222 always guide and limit the movement of the first chuck 24 and the second chuck 25, ensuring that the first chuck 24 and the second chuck 25 move along the predetermined trajectory, making the clamping action more stable and accurate.

[0042] Furthermore, the second guide groove 221 and the third guide groove 222 are axially symmetrical, and the central axis of the first guide groove 211 is perpendicular to the normal plane containing the axis of symmetry of the second guide groove 221 and the third guide groove 222. The symmetry of the second guide groove 221 and the third guide groove 222 ensures that the first chuck 24 and the second chuck 25 are subjected to uniform force and have symmetrical movement trajectories during movement, thereby guaranteeing a uniform and consistent change in the positioning gap.

[0043] In some embodiments, the second guide plate is made of 45 steel. To make the structure compact and reduce friction during movement, the inclination angles of the second guide groove and the third guide groove are -20° and 20°, respectively.

[0044] Furthermore, the mounting base also includes a fixing plate 23, which is fixedly connected to the movable end. The second guide plate 22 is fixedly connected to the fixing plate 23. The first guide plate 21 is disposed between the fixing plate 23 and the second guide plate 22, and the first guide plate 21 is connected to the drive mechanism 30 for transmission.

[0045] Specifically, when the drive mechanism 30 is activated, the power transmission component connected to the first guide plate 21 will drive the first guide plate 21 to move horizontally along a direction perpendicular to the central axis of the first guide groove 211. Since the second guide plate 22 is fixed, the movement of the first guide plate 21 will cause the first clamp 24 and the second clamp 25, which pass through the first guide groove 211, the second guide groove 221, and the first guide groove 211 and the third guide groove 222, to slide within their respective guide grooves. As the first guide plate 21 moves, the clamps gradually move closer to or further away, thereby achieving the clamping or releasing action on the paracord.

[0046] Furthermore, the first guide plate 21 is movable in the horizontal direction along the central axis of the first guide groove 211.

[0047] Furthermore, the drive mechanism 30 includes a first drive motor 31, a second drive motor, a first lead screw 32, and a second lead screw. The first drive motor 31 and the second drive motor are respectively mounted on the fixed plate 23. The first lead screw 32 is connected to the output end of the first drive motor 31, and the second lead screw is connected to the output end of the second drive motor. The first guide plate 21 has a first threaded hole 212 and a second threaded hole 213 in a horizontal direction perpendicular to the central axis of the first guide groove 211. The first lead screw 32 is threaded to the first threaded hole 212, and the second lead screw is threaded to the second threaded hole 213. Preferably, the first threaded hole 212 and the second threaded hole 213 are located on both sides of the first guide groove 211.

[0048] Specifically, when it is necessary to adjust the positioning gap between the first chuck 24 and the second chuck 25 to grip or release the paracord, the first drive motor 31 and the second drive motor start simultaneously to drive the first lead screw 32 and the second lead screw to rotate respectively. Due to the threaded connection between the first lead screw 32 and the second lead screw and the first threaded hole 212 and the second threaded hole 213 on the first guide plate 21, the rotational motion is converted into linear motion, causing the first guide plate 21 to move in a horizontal direction perpendicular to the central axis of the first guide groove 211. As the first guide plate 21 moves, the first chuck 24 and the second chuck 25 slide in the first guide groove 211, the second guide groove 221 and the first guide groove 211 and the third guide groove 222 respectively, thereby gradually moving closer or further away to achieve a uniform change in the positioning gap.

[0049] Furthermore, the width of the first guide groove 211 is greater than the width of the second guide groove 221 and the width of the third guide groove 222. The first connector 241 includes a first diameter portion 2411, a second diameter portion 2412, and a first connecting portion 2413. The first diameter portion 2411 is located in the first guide groove 211, and the second diameter portion 2412 is located in the second guide groove 221. The diameter of the first diameter portion 2411 is greater than the width of the second guide groove 221. The first connecting portion 2413 is located on the side of the second guide plate 22 away from the first guide plate 21. The first rubber part 242 is snapped into the first connecting portion 2413. The minimum outer diameter of the first rubber part 242 is greater than the width of the second guide groove 221.

[0050] Furthermore, the moving mechanism 10 is a linear motor.
