As shown in fig. 10 and 11, the relative position of the positioning end 321 of the positioning device 3 is adjusted, and thus the width L of the assembly gap 400 between the cover plate 200 and the base 300 is adjusted, and after the assembly gap 400 around the periphery of the cover plate 200 is adjusted uniformly, the positioning device 3 is locked, so that the position of the positioning end 321 is fixed. Finally, will again the utility model discloses carry out the pressurize in sending to the hot melt adhesive machine for the hot melt adhesive solidifies and with apron 200 and base 300 fixed connection in assembly gap 400. Finally, the cover plate 200 and the base 300 are removed from the receiving cavity 11 after the front plate 2 is removed.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
