ABSTRACT:
A hand tool having an elongated plunger assembly that is rotatably and movably disposed in a socket. The plunger assembly can be rotated between a first orientation and a second orientation as well as being moved between a first, withdrawn position and a second, extended position. The plunger assembly also has an upper notch and a lower notch on a front side and at least one generally flat lateral side. A fixed latch member extends across a portion of the socket and defines a narrow passage within the socket. The hand tool, preferably, includes a compression spring biasing the plunger assembly toward the extended position.
