Abstract
A testing device includes a circuit board, a carrier, a probe pin, a main body, a shaft, a pressing portion and a resilient spiral spring. The carrier is used to hold a device under test (DUT). The probe pin is electrically connected to the circuit board and the DUT. The shaft is movably connected to the main body with a screwing rotation method. The pressing portion is connected to one end surface of the shaft. The resilient spiral spring is retractably coiled on the shaft, and one end of the resilient spiral spring being far away from the shaft extends in a transverse direction intersecting an axial direction of the shaft.
