[0061] S1. Tensile test: First, power on and start the conveyor mechanism 1, place the detection mechanism 2 with the connecting wire in the limit slot 1023, then the servo motor 1013 will drive the conveyor belt 1021. When the conveyor belt 1021 is reciprocating, it will drive the detection mechanism 2 to move towards the support arc plate 1032. When the detection mechanism 2 contacts the guide arc plate 1033, the detection mechanism 2 will be stretched, thereby performing a tensile test on the connecting wire in the detection mechanism 2 until the detection mechanism 2 moves out of the guide arc plate 1033 to complete the tensile test.

The connecting plate (2041) is bolted to the front side of the reset spring (2043), and the limiting slot (2042) is opened on the rear side of the connecting plate (2041); the test assembly (205) includes a tester body (2051), a reset slide rod (2052) and a connecting hole (2053), the rear side of the reset slide rod (2052) passes through the connecting plate (2041) and is slidably connected to the connecting plate (2041), the tester body (2051) is bolted to the front side of the reset slide rod (2052), and the connecting hole (2053) is opened on the rear side of the tester body (2051); The detection method includes the following steps: First, power on and start the testing mechanism (2). Then, place the connection wire to be tested into the limit buckle (2021) in the limit box (2011). Connect the rear end of the connection wire to the wiring port (2013). Then, place the front end of the connection wire into the limit buckle groove (2023) and the limit slot (2042) in sequence. Then, insert the front end of the connection wire into the connection hole (2053). Then, press the tester body (2051) backward. At this time, the tester body (2051) and the detector body (2012) are connected. The power-on test will be performed on the connecting wire. When the limit box (2011) moves, the L-shaped plate (2031) will limit the limit box (2011) on the auxiliary slide rail (2033) and move it. At the same time, when the connecting plate (2041) contacts the conveying mechanism (1), it limits the limit box (2011) and allows the conveying mechanism (1) to perform a stretch test on the connecting wire until the connecting plate (2041) leaves the conveying mechanism (1). The reset spring (2043) will reset the limit slot (2042).
