The main function of the carrier net film for the transmission electron microscope is to load a small-scale sample during electron microscope observation, and a common single carrier net is generally used for loading the sample. When the magnetic material is observed by a transmission electron microscope, in order to avoid the magnetic material from being adsorbed on a pole shoe of the transmission electron microscope, a duplex carrier net (two carrier nets) is often used for clamping a sample to form a sandwich structure, so that the fixation of the sample is enhanced. Because the duplex carrying net is small in size, the clamping method for folding the duplex carrying net by using the conventional tweezers has the following problems: 1. the folding is not accurate, so that the grid cannot be placed on the transmission electron microscope sample rod; 2. the net is easy to be damaged by the tweezers in the clamping process; 3. the clamping efficiency is low. In order to solve the above problems more effectively, it is necessary to invent a clamping device for a twin load net for a transmission electron microscope.
