In addition, a plurality of wire grippers 300 are eccentrically formed based on the central axis of the rotation plate 200. That is, the wire gripper 300 is formed on the front side of the rotating plate 200.

Here, the wire gripper 300 serves to hold and fix the other side of the wires 2, one side of which is fixed and arranged side by side. At this time, when the rotating plate 200 is rotated by an external force, the wire gripper 300 is twisted with the wire (2) while rotating together with the rotating plate 200.

Here, although not shown, one side of the wire 2 may be fixed by the wire gripper 300 according to the present invention, or may be fixed in various ways.

In particular, the wire gripper 300 is preferably arranged on a circular trajectory based on the central axis of the rotation plate 200. This is to allow all the wire grippers 300 to be rotated along the circular trajectory so that the wires 2 bited by the respective wire grippers 300 are twisted uniformly.

Meanwhile, the wire gripper 300 includes a first stick 310, a second stick 320, and a bush 330.

The first stick 310 forms a main axis of the wire gripper 300. That is, the first stick 310 supports the second stick 320 and the bush 330.

The first stick 310 is rotatably formed on the one side of the first roller 312. In particular, the first roller 312 is rotatably formed at one edge of the first stick 310. In addition, the first roller 312 is formed to be capable of forward rotation with respect to the central axis.

In addition, the second stick 320 is formed to be hinged to the peripheral surface of the first stick (310) the other side. That is, the second stick 320 is formed to be spaced apart or narrowed with respect to the first stick 310.

Of course, the first stick 310 and the second stick 320 may be applied in various materials and various shapes.

In addition, the second stick 320 rotatably forms the second roller 322 on one side. In particular, the second roller 322 is rotatably formed at one edge of the second stick 320 to face the first roller 312. Thus, when the first stick 310 and the second stick 320 are in contact with each other, the first roller 312 and the second roller 322 are also in contact with each other. At this time, since the first roller 312 and the second roller 322 are rotatably formed on the first stick 310 and the second stick 320, respectively, they make cloud contact with each other.

Here, the first roller 312 and the second roller 322 accommodates and contacts the wires 2 therebetween in contact with each other and serves to press and fix the circumferential surface of the wires 2.

At this time, the second roller 322 is connected to the second stick 320 to be eccentrically rotated about the central axis. This is for firmly pressing and fixing the wires 2 having various diameters between the first roller 312 and the second roller 322.

Here, the wire 2 is received between the first roller 312 and the second roller 322 along the axial direction of the first stick 310, the first roller 312 and the second roller 322 is In order to prevent the wire 2 from being separated along the axial direction of the first stick 310, the wire 2 is brought into rolling contact correspondingly.

On the other hand, the bush 330 serves to contact or release the contact of the first stick 310 and the second stick (320).

That is, the bush 330 is formed on the circumferential surface of the first stick 310 to be movable along the axial direction of the first stick 310.

Thus, when the bush 330 moves in one direction of the first stick 310 and simultaneously presses the first stick 310 and the second stick 320 in directions facing each other, the first stick 310 and the second stick are pressed. The stick 320 is in contact with each other while narrowing based on the hinge connection portion. Of course, while the first stick 310 and the second stick 320 is in contact with each other, the first roller 312 and the second roller 322 are in contact with each other.

Particularly, when the first roller 312 and the second roller 322 are in contact with each other, the first stick 310 and the second stick 320 may be minutely opened with respect to the hinge connection portion.

On the contrary, when the bush 330 moves in the other direction of the first stick 310 and releases the pressing force of the second stick 320, the first stick 310 and the second stick 320 may have a natural or external force. They do not come into contact with each other. Of course, when the first stick 310 and the second stick 320 are opened with respect to the hinge connection portion, the first roller 312 and the second roller 322 are also opened.

Therefore, contact between the first stick 310 and the second stick 320 means that the first roller 312 and the second roller 322 are in contact with each other.

Here, the bush 330 is preferably formed in a cylindrical shape to axially insert the first stick (310). Of course, the bush 330 can be modified into various shapes.

On the other hand, the first roller 312 and the second roller 322 is formed a buffer member 340 on the circumferential surface or itself is made of a buffer member 340. For convenience, the first roller 312 and the second roller 322 is shown to further form a buffer member 340 on the circumferential surface.

The buffer member 340 is for preventing the damage of the coating of the wire 2 when pressing the circumferential surface of the wire (2). At this time, the buffer member 340 is preferably formed of a material having a large buffering force, such as silicone resin.

In addition, the bush 330 may pressurize the first stick 310 and the second stick 320 in a state in which the bush 330 is automatically advanced to one side of the first stick 310. Of course, the bush 330 is preferably installed to be reversed to the other side of the first stick 310 by the external force.

As an example, the first stick 310 is formed to detachably support the support member 352 at the end, the bush 330 is elastically pushed while the contact state of the first roller 312 and the second roller 322. The grip elastic member 354 elastically supported by the support member 352 is accommodated to maintain it.

That is, the support member 352 is larger in diameter than the first stick 310, and is preferably detachably attached to the other side of the first stick 310.

In particular, the support member 352 is inserted and fixed to the rotary plate 200. The supporting member 352 is inserted into the rotating plate 200 and fixed in various ways such as interference fit.

In addition, one side of the grip elastic member 354 is supported on the side surface of the support member 352, and the other side supports the bush 330.

Therefore, the bush 330 is always maintained in the one direction of the first stick 310 by the elastic support of the grip elastic member 354.

Of course, when the user pushes the bush 330 in the other direction of the first stick 310, the bush 330 moves in the other direction along the axial direction of the first stick 310 and at the same time, the grip elastic member 354. ) Is compressed.

In addition, when the external force is removed, the bush 330 is in contact with the first roller 312 and the second roller 322 while automatically moving in one direction of the first stick 310 by the elastic restoring force of the grip elastic member 354. State is maintained.

At this time, the grip elastic member 354 is preferably a compression coil spring.

In particular, the bush 330 is preferably in contact with the other side of the grip elastic member 354 by extending the locking jaw member 356 inward.

In addition, the bush 330 is preferably provided with a guide member (not shown) of various shapes to prevent the lateral bending of the grip elastic member 354.

On the other hand, when the bush 330 is forcibly pushed in the other direction of the first stick 310 by the external force, it is preferable that the first stick 310 and the second stick 320 is automatically opened based on the hinge connection portion. . This is to provide convenience for the worker, such as pushing the bush 330 with one hand and inserting the wire 2 between the first roller 312 and the second roller 322 with the other hand.

For example, the first stick 310 and the second stick 320 are supported by the support elastic member 362 and elastically open when the external force is pressed by the bush 330.

That is, the support elastic member 362 is interposed between the first stick 310 and the second stick 320 to elastically support the second stick 320 with respect to the first stick 310.

Thus, when the bush 330 is elastically supported by the grip elastic member 354 and maintains contact between the first roller 312 and the second roller 322, the support elastic member 362 is compressed. It becomes a state.

On the contrary, when the bush 330 removes the pressing force of the second stick 320 while moving in the other direction of the first stick 310 by the external force, the support elastic member 362 is the second stick by the elastic restoring force. Push 320. Therefore, the first stick 310 and the second stick 320 are opened based on the hinge connection portion.

In particular, the support elastic member 362 can be bent in the lateral direction.

Thus, the first stick 310 and the second stick 320 form a receiving groove 364 to accommodate each end of the support elastic member 362. The receiving groove 364 serves to prevent the detachment of the support elastic member 362 and to prevent bending.

At this time, the support elastic member 362 is preferably a compression coil spring.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
