[0002] Flat cables and electronic cables are a type of connecting cable, which is made of multiple thin wires bonded together.

[0003] At present, flat cables have been widely used in signal transmission or power connection of computers, home appliances, communication equipment, and digital devices. A terminal is pressed at one end of the flat cable for connection between the flat cable and the flat cable connector.

[0004] This not only facilitates the assembly of electronic equipment, but also ensures the reliability of signal transmission and connection between circuit boards inside electronic equipment or between electronic equipment; the other end of the cable needs to be twisted and then tinned.

[0005] Later, there was a need to process the terminals of wires of different lengths by tinning and riveting. However, the existing cables of different lengths need to be manually cut to a specific length, which has low processing efficiency and high labor costs. In addition, the manual error is large, which easily causes a certain degree of waste of wires and affects subsequent processing.

[0006] Therefore, in the utility model patent application, the applicant carefully studied a short wire stretching device for wire processing to solve the above problems. Utility Model Content
