The hanging plate 7 is provided with a vertical through-hole 71 for the underwear to be inserted laterally to limit the back buckle from falling from above. The clamping slit of the upper clip 3 corresponds to the hanging slit 71 up and down. The frame 1 is provided with a pushing device that can push the underwear inserted in the hanging slit 71 out from below the hanging plate 7 and detach it from the hanging plate 7. A material receiving device is provided below the lower clip 4 for catching the underwear falling from above. The upper driving device, the lower driving device, the stretching driving device and the pushing device are electrically connected to the control system 2 respectively.

[0029] During the tensile test, the distance between the upper clip 3 and the lower clip 4 is adjusted, and the upper clip 3 and the lower clip 4 are opened first. The staff holds the back buckle 1A in one hand and the cup in the other hand, and the back buckle 1A of the bra is facing upward and the bra 1B is facing downward, with the back buckle 1A facing the gap of the opened upper clip 3, and the upper end of the bra 1B facing the sling 71. The upper end of the bra 1B is inserted into the sling 71 sideways, and the lower end of the bra 1B is inserted sideways into the gap of the lower clip 4. The cup is located below the lower clip 4. Figure 3 As shown, release the hand holding the back buckle 1A, and the back buckle 1A falls on the hanging plate 7. Hold the cup at the lower end to pull the bra. The upper drive device and the lower drive device drive the upper clip 3 and the lower clip 4 to clamp respectively to complete the fixation of the bra. Then start the stretching drive device to drive the lower clip 4 to move downward for the bra stretching test. The stretching drive device drives the lower clip 4 to move up and down once to complete one stretching. After the stretching is completed, the upper drive device and the lower drive device drive the upper clip 3 and the lower clip 4 to release respectively, and the pushing device is started to push the bra 1B out of the hanging seam 71 and make the back buckle 1A separate from the hanging plate 7, so that the tested bra automatically falls onto the material receiving device.

When collecting materials, the hanging rod 10 is pulled out, and the bras on the receiving tray 8 are hung on the hanging rod 10 one by one, so as to quickly and neatly collect the bras.
