In this embodiment, because the fixing base 31 is disposed at the edge of the working board 20, and the elastic extension base 32 is disposed at one side of the fixing base 31 away from the working board 20, the elastic extension base 32 elastically deforms to abut against the opposite sides of the electronic device 1000 in cooperation with the fixing base 31, thereby fixing the electronic device 1000, when the electronic device 1000 is placed between the elastic extension base 32 and the fixing base 31, the working board 20 can be avoided from sinking to the preset depth along the length direction thereof, when the electronic device 1000 sinks to the preset depth, the elastic extension base 32 and the fixing base 31 can be clamped to the center of gravity of the electronic device 1000, thereby ensuring that the electronic device 1000 does not shake when the two-dimensional measuring instrument measures the thickness of the electronic device 1000.
