At this time, the connecting lines 3 on both sides of the support block 401 are wound around the winding rod 406, and the connecting lines 3 are clamped in the arc groove of the connecting seat 407. At this time, the fixed plate 403 is rotated 10, and then move the fixed plate 410 toward the connecting seat 407, and rotate the screw rod 411 to insert it into the connecting seat 407, so as to fix the winding and rolled connecting wire 3, and the protective pad 408 can effectively reduce the damage of the connecting wire 3 after being squeezed. By setting the winding device 4, the winding effect of the connecting wire 3 on the pressure vessel leakage detection device is improved, and the damage of the connecting wire 3 after winding is reduced, which facilitates the fixation of the wound connecting wire 3 and improves the practicality of the pressure vessel leakage detection device as much as possible.
