Abstract: A pin regulator for an electronic component includes a base seat, a regulating member rotatably connected on the base seat, and a driving module assembled on the base seat. The base seat defines a latching groove, and a sidewall of the latching groove defines a plurality of regulating slots to receive the pins of the electronic component therein. The driving module is rotatably connected to the regulating member to engage the regulating member in the latching groove.

Abstract: A manipulator includes a support arm, a grasping member, and a connecting assembly. The connecting assembly connects the support arm with the grasping member. A base is fixed to the support arm, and the holder is fixed to the base. The holder defines an assembling hole, and a perimeter of the assembling hole increases along a direction towards the base. The connecting member has a first assembling portion received in the assembling hole of the holder. The elastic member is positioned between the base and the connecting member, thus producing an elastic force to drive the connecting member to resist the holder.
