[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5 An embodiment of this utility model is provided: an easy-to-use auxiliary device for road signal cable splicing, including a device base 1, a device frame 2 fixed to the top of the device base 1, a battery box 9 installed on one side of the top of the device base 1, a geared motor 6 installed on the top of the battery box 9, and a wire feeding wheel 7 installed at the output end of the geared motor 6, and the surface of the wire feeding wheel 7 is provided with equally spaced protruding teeth 8.

[0024] Specifically, one end of the cable is extended below the cable feeding wheel 7. The cross-section of the cable is observed. The first bidirectional lead screw 3 is rotated so that the first sleeve 4 drives the upper cutting blade 5 to move down and the lower cutting blade 5 to move up. The cutting blade 5 is aligned with the connection between the cable sheath and the core. Then, the controller 10 is operated so that the geared motor 6 drives the cable feeding wheel 7 to rotate. The cable feeding wheel 7 pushes the cable toward the cutting blade 5 through the teeth 8. At this time, the cable passes through the cutting blade 5, and the cutting blade 5 cuts open the upper and lower sheaths of the cable, so that the cable sheath can be quickly stripped off. Both the upper and lower sheaths are cut open, making the removal of the sheath easier and more convenient. Moreover, the cut position is at the connection between the sheath and the core, so as not to damage the core.

[0025] A first bidirectional lead screw 3 is installed on one side of the top of the device base 1, and a first sleeve 4 is fitted on the outer wall of the top and bottom of the first bidirectional lead screw 3. The first sleeve 4 is threadedly connected to the first bidirectional lead screw 3. A guide rod 12 is fixed on the other side of the top of the device base 1, and a second sleeve 13 is slidably fitted on the outside of the guide rod 12. A cutting blade 5 is provided between the first sleeve 4 and the second sleeve 13.

[0026] The device base 1 has a drive cavity 18 inside, and a second bidirectional lead screw 19 is installed inside the drive cavity 18. One end of the second bidirectional lead screw 19 extends to the outside of the device base 1 and is equipped with a handwheel 17. Slider 20 is fitted on the outer walls on both sides of the second bidirectional lead screw 19. The slider 20 is threadedly connected to the second bidirectional lead screw 19. The top end of the slider 20 extends to the top of the device base 1 and is fixed with a limit clamp 11.

[0027] The inner wall of the limiting clamp 11 is provided with a groove 15, and the groove 15 is equipped with equally spaced guide rollers 16; the inner wall of the limiting clamp 11 below the guide rollers 16 is provided with an inclined surface 14.

[0028] Specifically, rotating the handwheel 17 causes the second bidirectional lead screw 19 inside the drive cavity 18 to rotate, causing the slider 20 to drive the limiting clamp 11 to move towards the cable simultaneously. The inclined surface 14 on the inner wall of the limiting clamp 11 contacts the cable, and the limiting clamp 11 limits the cable. The guide roller 16 inside the groove 15 contacts the cable and guides the cable. The guide roller 16 and the cable are in rolling contact, resulting in low frictional resistance.

[0029] The two ends of the cutting blade 5 extend into the interior of the first sleeve 4 and the second sleeve 13 respectively and are connected to the first sleeve 4 and the second sleeve 13 by bolts;

[0030] A controller 10 is installed on one side of the battery box 9, and a storage battery is installed inside the battery box 9;

[0031] Two sets of the first sleeve 4 and the second sleeve 13 are provided respectively, and the first sleeve 4 and the second sleeve 13 have the same height.

[0032] In this embodiment, the following steps are taken: First, one end of the cable is extended below the cable feeding wheel 7. Second, the handwheel 17 is rotated to rotate the second bidirectional lead screw 19 inside the drive cavity 18, causing the slider 20 to move the limiting clamp 11 towards the cable. The inclined surface 14 on the inner wall of the limiting clamp 11 contacts the cable, limiting the cable. The guide roller 16 inside the groove 15 contacts the cable, guiding it. The guide roller 16 and the cable have rolling contact, resulting in low frictional resistance. Then, the cross-section of the cable is observed, and the first bidirectional lead screw 3 is rotated to make the first The sleeve 4 moves the upper cutting blade 5 downward and the lower cutting blade 5 moves upward, aligning the cutting blade 5 with the connection between the cable sheath and the core. Then, the controller 10 drives the geared motor 6 to rotate the wire feeding wheel 7. The wire feeding wheel 7 pushes the cable toward the cutting blade 5 through the teeth 8. At this time, the cable passes through the cutting blade 5, which cuts open the upper and lower sheaths of the cable, making it easy to quickly strip the cable sheath. Both the upper and lower sheaths are cut, making the removal of the sheath effortless and convenient. Moreover, the cut is at the connection between the sheath and the core, so the core will not be damaged.

[0033] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
