[0001] The utility model relates to the technical field of line couplers, in particular to a scissor-type line coupler. Background Art

[0002] When installing wires, some wires need to be connected together to ensure the connectivity of the circuit. In the past, technicians mostly used pliers to manually connect the wires. This traditional operation method takes a certain amount of time and effort, and manual operation is easy to hurt the hands. Currently, most technicians use a wire coupler to connect the wires. A square shaft is set at the bottom of the wire coupler and is driven by an electric drill to drive the wire coupler to rotate, while pliers are used on the other side to fix the wires, so that the wires can be connected during winding.

[0003] However, this type of wire paralleler that can only be used for paralleling by an electric drill still has some defects. This type of wire paralleler is too dependent on the electric drill to drive it, which limits the usage scenarios and environments. It is inconvenient for work environments where there is no power supply or an electric drill cannot be used. Moreover, the wire paralleler and the electric drill need to be used together, which is not easy to carry. Based on this, we have redesigned a scissor-type wire paralleler to solve the above problems. Utility Model Content

[0022] In specific implementation, the rotary assembly includes a rotary column 10, a threading hole 12, a ratchet 14 and an external gear 15;

[0023] The rotating column 10 is arranged in the inner cylinder of the damping bearing 11 and is adapted to be located in the inner cavity of the connecting cylinder 7. The front and rear sides of the rotating column 10 extend to the outer surface of the connecting cylinder 7. The front center and the front outer circumference of the rotating column 10 are both provided with threading holes 12. The ratchet 14 is arranged on the front side of the rotating column 10. The external gear 15 is rotatably arranged on the front side of the rotating column 10, and the external gear 15 is sleeved on the outside of the ratchet 14. The inner wall of the external gear 15 is connected with a ratchet pawl that cooperates with the ratchet 14 through a rotating shaft. The external gear 15 and the fan-shaped rack 6 are meshed with each other. Through the cooperation between the ratchet pawl on the external gear 15 and the ratchet 14, and the cooperation with resistance of the rotating column 10 and the ratchet 14 under the action of the damping bearing 11, when the external gear 15 rotates, the ratchet 14 and the rotating column 10 are driven to rotate. When the external gear 15 rotates in the opposite direction, the ratchet 14 and the rotating column 10 do not rotate.

[0024] In specific implementation, in order to facilitate the scissor-like installation of the second grip 4 on the first grip 1, a positioning pin 3 is provided in the middle of the front side of the first grip 1, and a mounting hole 9 is opened in the middle of the front side of the second grip 4. The second grip 4 can be rotatably set on the first grip 1 through the cooperation of the positioning pin 3 and the mounting hole 9.

[0025] In specific implementation, in order to facilitate the user to hold the first grip 1 and the second grip 4 with one hand and drive the second grip 4 to rotate, the outer side of the first grip 1 and the outer wall of the second grip 4 are respectively provided with a first arc baffle 2 and a second arc baffle 5.

[0026] In specific implementation, in order to facilitate the stripping when paralleling, a stripping blade 13 is further provided on the front side of the threading hole 12 on the outer circumference of the front side of the rotary column 10.

[0027] In specific implementation, in order to realize that the external gear 15 and the rotating column 10 can be rotatably installed together, the rear wall surface of the external gear 15 is integrally formed with a circular convex ridge, and is rotatably embedded in the front surface of the rotating column 10 through the convex ridge.

[0028] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows:

[0029] When in use, the wires to be paralleled are respectively inserted into the middle threading hole 12 and the outer threading hole 12. The user holds the first grip 1 and the second grip 4 with one hand, and clamps the wires with pliers with the other hand. With the cooperation of the first arc baffle 2 and the second arc baffle 5, the user gradually opens his hand to cause the second grip 4 to rotate outward, and drives the sector rack 6 to rotate with the positioning pin 3 as the axis. Under the meshing cooperation between the sector rack 6 and the outer gear 15, the outer gear 15 can be driven to rotate, and the outer gear 15 drives the ratchet pawl on its inner wall to rotate on the ratchet 14 one by one. Gradually turn the lever without driving the ratchet 14 to rotate. When the user re-grips the first grip 1 and the second grip 4 and pulls the second grip 4 back, the sector rack 6 rotates in the opposite direction and drives the outer gear 15 to rotate in the opposite direction. The outer gear 15 drives the ratchet 14 to rotate through the pawl, and the ratchet 14 drives the rotary column 10 to rotate, thereby performing a parallel operation on the wires passed through the threading holes 12. Repeated operations can be performed gradually according to the length of the parallel wires required. This operation does not rely on the drive of an electric drill, is convenient for users to perform parallel work, and is easy to carry.

It is obvious that those familiar with the technology in this field can easily make various modifications to the embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the protection scope of the utility model.
