After the gripping of the front side plate 430 is completed, the front side plate 430 is placed on the front side of the bottom plate 410 by the movement of the gripping jaw 330 relative to the longitudinal hanger 310 and the transverse hanger 320, and the rear side surface of the front side plate 430 abuts against the front side surface of the bottom plate 410. The first pressing member 251 located at the front side of the bottom chassis 210 is moved toward the center of the bottom chassis 210 so that the first pressing member 251 abuts the front side plate 430 and presses the front side plate 430 against the bottom plate 410. The pressure maintaining sensor between the abutting surfaces of the front side plate 430 and the bottom plate 410 monitors the pressing force between the two in real time, so that a user can conveniently adjust the pressure maintaining sensor according to actual requirements. The front side plate 430, the left and right side plates 420 and the rear side plate 440 are hoisted in sequence by the hoisting mechanism 300; so that the first pressing member 251 located at the front end of the bottom chassis 210 presses the front side plate 430 and the bottom plate 410 in the longitudinal direction; the second pressing member 252 presses the left and right side plates 420 against the bottom plate 410 and the front side plate 430 in the lateral direction; the rear side plate 440 is pressed against the rear sides of the bottom plate 410 and the left and right side plates 420 by the first pressing member 251 located at the rear end of the bottom chassis 210.
