when auxiliary extraction is carried out on the plug-in positioning piece 6, the stress clamping plate 5 slides forwards and backwards to enable the two U-shaped clamping grooves on the stress clamping plate 5 to be in clamping fit with the top end parts of the two plug-in positioning pieces 6 corresponding to the front and back and to be propped against the bottom of the lifting disc, the stress clamping plate 5 is in clamping connection with the plug-in positioning pieces 6 to enable hammering extraction force to be transmitted to the plug-in positioning pieces 6, and as the hammering frame 402, the two connecting rods 405 and the sliding positioning frame 404 are jointly connected to form a crank slide block mechanism, the front and back sliding hammering frame 402 can drive the sliding positioning frame 404 to slide upwards and downwards, the stress clamping plate 5 is connected with the sliding positioning frame 404 through the two longitudinal sliding shafts 502 in a sliding manner, and then the back hammering frame 402 can push the sliding positioning frame 404 and the side, which is far away from the transverse supporting plate 1, of the plug-in positioning pieces 6 after being subjected to impact deformation bending can be driven to be pulled out in an auxiliary manner, and the breast plate 3 is loosened;
normally, the stress clamping plate 5 slides in the interval space between the two rows of plug-in positioning pieces 6, so that blocking interference caused by left-right sliding adjustment of the auxiliary dismounting assembly 4 is avoided, the threaded driving shaft 403 can be positively and negatively rotated to drive the two longitudinal sliding shafts 502 and the stress clamping plate 5 to slide forwards and backwards, the two plug-in positioning pieces 6 corresponding to the front and the back are selected to be clamped and inserted for auxiliary hammering extraction, and the whole auxiliary dismounting assembly 4 and the stress clamping plate 5 can slide left and right along the two transverse supporting frames 104 and are matched with the two rows of plug-in positioning pieces 6 positioned at the same position for auxiliary extraction through the two clamping sleeves 401;
the positioning bolt can fix the front clamping sleeve 401 in a plugging manner, so that the auxiliary dismounting assembly 4 is kept at a position corresponding to a certain plugging positioning piece 6 after sliding adjustment, and in addition, the plug 602 is used as a plugging force bearing component for the T-shaped sliding block and the breast board 3, and can be independently rotated, dismounted and replaced after being subjected to impact deformation.
