The pull-out test equipment in the prior art usually includes a carrier plate for placing the panel, a down-pressing assembly for positioning the parts and the panel, and an upper pulling assembly for applying a pulling force to the locked parts. During testing, the parts are locked on the panel by the down-pressing assembly, and then a pulling force is applied to the parts by the upper pulling assembly. Figure 1 The result of the pull-out test needs to be fed back to the electric control module. The electric control module is electrically connected with a magnetic switch, which is arranged at the output end of the upper pulling assembly to detect whether the output end of the upper pulling assembly produces an upward displacement, thereby detecting the result after the upper pulling assembly is subjected to a pulling force and feeding back the detection result to the electric control module.
