[0001] The invention belongs to the technical field of plugging and pulling force testing, and in particular relates to a full-automatic plugging and pulling force testing device. Background Art

[0002] Many data cables, power cables and other connecting cables used in electronic devices such as mobile phones, computers, servers, and various mobile electronic devices such as USB flash drives need to undergo corresponding plug-in and pull-out force tests between plugs and sockets during the manufacturing process to ensure that they meet the specific requirements of each connector. With the continuous development of technology, plug-in force has evolved from traditional manual and semi-automatic to fully automated.

[0003] The existing fully automatic plugging and extraction force tester has at least the following problems in actual use: First, the fully automatic plug-in force tester currently needs to be connected to an external computer no matter what kind of test project it performs, and it is implemented by calling the test program in the computer. This not only requires high literacy of the operator, but also is cumbersome to operate. Second, the calibration time is too long during clamping, affecting the test efficiency.

[0004] Therefore, the above problems need to be solved urgently. Summary of the invention
