The utility model relates to electronic component testing equipment technical field especially a general diode test seat, including base, upper cover, at least two claw type elastic probe and connecting assembly, the base is along its length direction and is set up through type bearing groove, the both ends of bearing groove length direction are coaxial cylindrical surface end wall, the upper cover is along its length direction and is set up through type cover groove, and the both ends of cover groove length direction are the arc end wall of coaxial with bearing groove end wall, the upper cover is through connecting assembly and covers on the base, makes bearing groove and cover groove position coincidence and forms the restraint cavity of diode middle part limit, claw type elastic probe position corresponds with the restraint cavity position and claw type elastic probe part extends in the outside of base and upper cover, can improve single equipment test containing capacity through the utility model, makes the test efficiency greatly improve.

A CNC machine tool for preparing high-precision graphite screws relates to the field of graphite threaded rod preparation equipment. It includes a transfer mechanism, a feeding mechanism, and an automatic grinding mechanism. The transfer mechanism includes a motor-driven transfer wheel. The feeding mechanism includes an inlet end for receiving graphite rods and a delivery fixing end for feeding the graphite rods to the automatic grinding mechanism. The delivery fixing end includes an openable and closable delivery fixing lip. The automatic grinding mechanism includes a worktable that can move closer to or further away from the delivery fixing end. The worktable is equipped with a rod-turning device that can reciprocate horizontally in the left-right direction of the delivery fixing lip. The rod-turning device includes a positioning arm and a grinding arm. The grinding arm has a rod-receiving mechanism on the side away from the positioning arm. The rod-receiving mechanism includes a receiving part and a collecting part. This invention has a high degree of automation and can mechanically pick up the graphite rods.
