And, the pushing member 2 is connected and fixed to the driving assembly 3, and is driven by the driving assembly 3 to move along the vertical direction of the preparation platform.
Further, when the base frame 1 is installed and positioned on the surface of the preparation platform through the supporting legs 12, the pushing surface 221 is parallel to the surface of the preparation platform; the pushing surface 221 can be pushed to press the decorative material to be bonded in a mode parallel to the preparation platform, so that the uneven thickness of the bonding layer caused by uneven stress of the decorative material can be effectively avoided, the preset thickness value of the tested bonding layer is more accurate, the test error is reduced, and the accuracy of the test result is improved.
