An adjustment groove 42 penetrating the bottom surface of the support column 41 is provided on the top surface of the support column 41. Sliding grooves 43 and at least two locking slots 44 are respectively provided on the two side walls of the support column 41 that are not in contact with the tail column 2. The sliding grooves 43 are located in the direction perpendicular to the extension of the guide plate 3.

[0057] Working principle:

[0058] First, according to the thickness of the prefabricated cover plate, the height of the roller 46 is adjusted, the appropriate height of the clamping groove 44 is selected, the bottom surface of the movable cavity is slightly higher than the ear plate of the prefabricated cover plate, then the pull rod 6 is pulled horizontally, at this time the driving wheel 5608 and the roller 46 do not produce contact, after the ear plate enters the movable cavity, the operating end of the pull rod 6 is pulled up, the pull rod 6 rotates, cooperates with the supporting arm 5609, the swing arm 5604 rotates, the driving wheel 5608 and the roller 46 abut each other, and under the action of the gravity of the main frame 1 and the prefabricated cover plate, sufficient friction between the driving force and the roller 46 is generated, power transmission is carried out, cooperates with the second transmission belt 5607, the second transmission wheel 5603 and the third transmission wheel 5606, the two first transmission wheels 5601 rotate synchronously, the auxiliary plate 54 rotates, and the auxiliary protrusions 55 move regularly in the through groove 52. When the prefabricated cover plate moves from the outside of the main frame 1 to the inside of the main frame 1, the horizontal movement direction of the auxiliary protrusions 55 in the through groove 52 is from the far end of the guide plate 3 to the near end of the tail column 2. At this time, the ear plate abutting on the supporting plate 51 moves with the main frame 1 under the action of the auxiliary protrusions 55, the prefabricated cover plate is inserted into the main frame 1, at this time the pull rod 6 is pulled up instantaneously, the pull rod 6 collides with the stop rod 7, and the prefabricated cover plate is helped to be demolded by force transmission. When the demolding is completed, the main frame 1 is pushed in the opposite direction, the roller 46 rotates in the opposite direction, at this time the auxiliary plate 54 reversely rotates, the auxiliary protrusions 55 reversely move, the mold plate is helped to be separated from the main frame 1, so that the demolding is more labor-saving and the labor intensity is reduced.
