Portable static electricity detection device

The utility model discloses a portable electrostatic detection device, which relates to the technical field of electrostatic detectors and comprises a protective shell, a rotating handle is arranged on one side of the protective shell, a bidirectional screw rod is connected to one side of the rotating handle, two groups of T-shaped nuts are connected to the outside of the bidirectional screw rod, and the two groups of T-shaped nuts are symmetrically distributed on the bidirectional screw rod. According to the electrostatic detection device, the rotating handle, the bidirectional screw rod, the T-shaped nuts, the clamping plate and the electrostatic detection host are arranged, the rotating handle is rotated, so that the rotating handle drives the bidirectional screw rod to rotate, the two sets of T-shaped nuts are connected to the outside of the bidirectional screw rod, the bidirectional screw rod drives the two sets of T-shaped nuts to move oppositely, the clamping plate is fixed above the T-shaped nuts, and
