[0023] In order to understand the technical content of the utility model more, specific embodiment is raised and the following is described with the accompanying drawings.

[0024] Combining Figure 1 And Figure 2 As shown in the utility model discloses a kind of line pressing tile positioning device for cord twisting, including pressing tile containing seat 10, cylinder 20 and pressing tile part 30, the slot that forms containing lower pressing tile 12 and upper pressing tile 13 is formed in pressing tile containing seat 10, and the two sides of the top of pressing tile containing seat 10 are equipped with the limit board 11 extending inwards.

[0025] Lower pressing tile 12 and upper pressing tile 13 are arranged in the slot, and the horn mouth for cord passing is formed between lower pressing tile 12 and upper pressing tile 13, and the cord is constrained and gathered and twisted through the horn mouth, wherein the tightness between lower pressing tile 12 and upper pressing tile 13 determines the gathering and twisting effect of cord, therefore, the certain pressure of lower pressing tile 12 and upper pressing tile 13 is conducive to improving the twisting effect.

[0026] In an optional embodiment, the bottom of the barrel 20 is provided with a limiting disc 21, the diameter of the limiting disc 21 is greater than the distance between the two limiting plates 11, the limiting disc 21 is arranged below the limiting plates 11, the pressing shoe component 30 penetrates the barrel 20, the first end extends below the limiting disc 21, and the second end is above the barrel 20, the pressing shoe component 30 is elastically connected with the barrel 20, so that the pressing shoe component 30 has a tendency to move towards the pressing shoe accommodating seat 10.

[0027] In this way, the pressing shoe component 30 downwardly abuts against the upper pressing shoe 13, the limiting disc 21 prevents the barrel 20 from moving upwardly below the limiting plates 11, and thus the pressing shoe component 30 keeps having downward pressure on the upper pressing shoe 13, so that the lower pressing shoe 12 and the upper pressing shoe 13 are tightly attached, and the twisted wire is twisted better.

[0028] As shown in Figure 2 the pressing shoe component 30 can only slide along the axial direction of the barrel 20 or rotate around the axial direction of the barrel 20 relative to the barrel 20, the pressing shoe component 30 is provided with a limiting structure 35, the outer wall of the barrel 20 is provided with a limiting groove 23, the limiting structure 35 is located in the limiting groove 23, and the limiting groove 23 comprises a first groove body 231 and a second groove body 232 which are in communication with each other.

[0029] When the limiting structure 35 is in the first groove body 231, the pressing shoe component 30 can only move along the axial direction of the barrel 20, abuts against the surface of the upper pressing shoe 13, and tightly presses the lower pressing shoe 12 and the upper pressing shoe 13 against each other, when the limiting structure 35 is in the second groove body 232, the pressing shoe component 30 can only rotate along the axial direction of the barrel 20, and at this time, the pressing shoe component 30 is out of contact with the upper pressing shoe 13.

[0030] In this way, when the lower pressing shoe 12 and the upper pressing shoe 13 need to be pressed against each other, the limiting structure 35 is moved into the first groove body 231, at this time, if the upper pressing shoe 13 moves upwardly due to the reaction force of the twisted wire, the pressing shoe component 30 can directly generate a reaction force due to the displacement of the upper pressing shoe 13, so as to prevent the upper pressing shoe 13 from moving upwardly, in the whole process, the moving direction of the upper pressing shoe 13 is towards the axial direction of the barrel 20, and the moving direction of the pressing shoe component 30 is also towards the axial direction, so that the direction of the upper pressing shoe 13 is stable when a small displacement is generated, when the lower pressing shoe 12 and the upper pressing shoe 13 do not need to be pressed against each other, i.e. the wire is put into or pulled out, the limiting structure 35 is moved into the second groove body 232, at this time, there is no pressure between the lower pressing shoe 12 and the upper pressing shoe 13, which is beneficial to the operation of putting the wire into or pulling the wire out.

[0031] As shown in Figure 3 the barrel 20 is configured as a cylindrical barrel, both ends of which are open, the first end of the barrel 20 is threadedly connected with the limiting disc 21, and the second end of the barrel 20 is detachably connected with the cover 22.

[0032] Optionally, the limiting disc 21 and the cover 22 are threadedly connected with the barrel 20, so as to facilitate the assembly of the device.

[0033] In combination Figure 3 As shown, the pressing tile part 30 comprises a guide column 31, the first end of the guide column 31 is connected with a pressing block 34, and the second end is connected with a handle 32, the pressing block 34 penetrates through the limiting disc 21 and is slidably connected with the limiting disc 21, a limiting structure 35 is connected to the guide column 31, and a spring 36 is arranged between the limiting structure 35 and the cover 22.

[0034] In an optional embodiment, the guide column 31 and the pressing block 34 are threadedly connected, the spacing between the guide column 31 and the pressing block 34 is changed by rotating the pressing block 34, and the force of the pressing block 34 pressing the upper pressing tile 13 can be finely adjusted.

[0035] In this way, the guide column 31 is provided with downward pressure by the spring 36, so that the lower pressing tile 12 and the upper pressing tile 13 are kept close to each other.

[0036] Preferably, the spring 36 is a circular compression spring, and the outer diameter of the spring 36 is smaller than the inner diameter of the barrel 20, so that the spring 36 can maintain a larger elastic potential energy, when the limiting structure 35 is in the second groove body 232, the spring 36 pushes the guide column 31, but the guide column 31 cannot move downward, at this time, the bottom of the pressing block 34 does not contact the upper pressing tile 13, when the limiting structure 35 is in the first groove body 231, the guide column 31 can move downward, so that the bottom of the pressing block 34 is pressed against the upper pressing tile 13.

[0037] In an optional embodiment, the pressing block 34 is configured in a cylindrical structure, and the diameter of the pressing block 34 is greater than 1 / 3 of the width of the upper pressing tile 13. In this way, the pressing block 34 and the upper pressing tile 13 have a larger contact area, which can better limit the upper pressing tile 13.

[0038] Further, the top of the pressing block 34 is provided with a disc-shaped structure 33 which is attached to the inner wall of the barrel 20. In this way, the stability of the movement of the pressing block 34 in the axial direction of the barrel 20 can be ensured.

[0039] In a specific embodiment, the limiting structure 35 comprises a telescopic rod, the root of the telescopic rod is connected to the guide column 31, and the head can extend into the limiting groove 23, when the telescopic rod is in the shortened position, the head can be retracted into the inner wall of the barrel 20, and when the telescopic rod is in the elongated position, the head can extend out of the outer wall of the barrel 20.

[0040] Thus, when the limiting structure 35 is installed into the limiting groove 23, the pressing block 34 and the guide column 31 are inserted into the cylinder 20 from the top of the cylinder 20, the pressing block 34 corresponds to the hole on the limiting disc 21, the limiting structure 35 contacts the top of the cylinder 20, the head of the telescopic rod is pressed to be shortened to fit the inner wall of the cylinder 20, when reaching the limiting groove 23, the head of the telescopic rod automatically pops out and is clamped in the limiting groove 23.

[0041] Further, the outer wall of the guide column 31 is provided with the first telescopic rod and the second telescopic rod arranged in a central symmetry, and the cylinder 20 is provided with the limiting groove 23 corresponding to the first telescopic rod and the second telescopic rod.

[0042] Thus, through the arrangement of the first telescopic rod and the second telescopic rod, the state of the guide column 31 being limited in the cylinder 20 is more stable.
