AI Technical Summary
Traditional tweezers require continuous force when holding TEM specimens, resulting in high labor intensity for operators and the specimens being prone to falling.
A TEM sample sampling device was designed, which uses a clamp body with a reset component and a positioning component. Automatic clamping and limiting are achieved through an arc-shaped guide rod and a reset spring, reducing the need for continuous squeezing by the operator.
It enables labor-saving clamping of TEM specimens, reduces the labor intensity of operators, and effectively prevents specimens from falling.
