[0002] In fields such as power engineering, building wiring, and communication facility installation, cable wiring is a crucial process for ensuring circuit connectivity and stability. The straightness of the conductors directly affects the wiring quality, conductivity, and service life. Therefore, it is necessary to assist in straightening the conductors during cable wiring. For example, patent document CN219900028U discloses a portable cable conductor straightening tool. This straightening tool can straighten the cable in the first step by setting a pair of rotating cylinders. When the worker rotates the threaded screw, the clamp moves to wrap the cables of different sizes. Then the worker can pull out the cable, which is now in a horizontal state. This tool can straighten cables of different sizes.

[0003] However, when the above-mentioned straightening tool straightens the wire, the operator needs to manually pull the wire. When the length of the wire to be straightened is long, it takes the operator a lot of time, which reduces the straightening efficiency. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses an electric wire straightening tool for cable wiring.

[0026] This utility model provides, for example Figure 1-4 The cable wiring electric wire straightening tool shown includes a base plate 1 and a first support frame 2 and a second support frame 3 fixedly mounted on the top of the base plate 1. The side of the first support frame 2 is provided with two symmetrically arranged first support rods 4. The rod wall of the first support rod 4 is fixedly sleeved with a guide roller 5. The outer wall of the guide roller 5 is provided with a wire groove 17.

[0027] The second support frame 3 has two symmetrically arranged second support rods 6 rotatably mounted on its side. A drive roller 7 is fixedly sleeved on the rod wall of the second support rod 6. A motor 10 is fixedly mounted on the outer wall of the second support frame 3. The output shaft end of the motor 10 is fixedly connected to the second support rod 6. Gears 11 are fixedly sleeved on the rod walls of both second support rods 6. The two gears 11 are configured to cooperate. A groove is opened at the end of the drive roller 7. Multiple axially evenly distributed drive teeth 8 slide through the side of the groove. A first spring 9 is sleeved on the outer wall of the drive teeth 8. The two ends of the first spring 9 are fixedly connected to the drive teeth 8 and the inner wall of the groove, respectively.

[0028] In order to ensure that the drive teeth can make full contact with the wire according to the wire specifications, such as Figure 1-2As shown, a drive ring 12 is provided in the groove. The drive ring 12 is rotatably sleeved with the second support rod 6. Multiple push blocks 13 with evenly distributed bearings are fixed on the outer wall of the drive ring 12. The push blocks 13 are in contact with the end of the drive teeth 8. A guide slope is opened at one end of the drive teeth 8 near the drive ring 12. The outer wall of the push block 13 is arc-shaped. A positioning rod 14 is slidably inserted inside the drive ring 12. Multiple axially evenly distributed positioning grooves 15 are opened on the inner wall of the groove. The end of the positioning rod 14 is inserted into the positioning groove 15. A second spring 16 is sleeved on the rod wall of the positioning rod 14. The two ends of the second spring 16 are fixedly connected to the positioning rod 14 and the drive ring 12 respectively. The positioning rod 14 is U-shaped.

[0029] Working principle: When in use, place one end of the wire to be straightened into the wire groove 17 of the guide roller 5. The wire passes through the wire groove 17 between the two guide rollers 5 and then between the two drive rollers 7. At this time, the extension length of the drive tooth 8 can be adjusted according to the specifications of the wire. Pull the U-shaped positioning rod 14 so that its end is disengaged from the positioning groove 15. The second spring 16 is stretched. Rotate the drive ring 12. The drive ring 12 drives the push block 13 to rotate. The arc-shaped outer wall of the push block 13 contacts the guide slope of the drive tooth 8, pushing the drive tooth 8 to slide outward along the groove. The first spring 9 is compressed until the ends of multiple drive teeth 8 are in close contact with the outer wall of the wire. Release the positioning rod 14. Under the elastic force of the second spring 16, the positioning rod 14 is inserted into the corresponding positioning groove 15 to fix the position of the drive ring 12.

[0030] The motor 10 is started, which drives the connected second support rod 6 to rotate. Through the meshing transmission of two gears 11, the two second support rods 6 drive the corresponding drive rollers 7 to rotate synchronously in opposite directions. When the drive rollers 7 rotate, the drive teeth 8 contact the outer wall of the conductor and generate friction, pushing the conductor to move continuously laterally. Under the squeezing and traction of the two guide rollers 5, the bent part of the conductor is straightened. At the same time, the conductor groove 17 of the guide rollers 5 guides the conductor, ensuring its stable movement direction. The entire process does not require continuous manual pulling of the conductor, achieving automatic straightening and improving work efficiency.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
