[0027] During testing, the armrest box 61 to be tested is placed on the positioning base plate 54, and its position is limited by the positioning fixture 55. After the photoelectric sensor 59 detects that the armrest box 61 is in place, the clamping cylinder 57 is activated, driving the movable clamping plate 58 to approach the fixed clamping plate 56, thereby completing the positioning and fastening of the armrest box 61. The piston rod of the longitudinal cylinder 31 extends downward, causing the slot of the locking block 42 to engage with the protrusion 63 of the roller shutter 62.
