ABSTRACT:
A driving assembly for driving opposed first and second driven members includes an elongated rod and a stop unit. The elongated rod extends through a through-hole of the second driven member. The elongated rod has an enlarged threaded first portion which is adapted to extend threadably through a screw hole of the first driven member and which is sized to prevent extension of the first portion through the through-hole of the second driven member, and a second portion which is adapted to extend out of the through-hole of the second driven member. The first and second portions of the elongated rod extend from two sides of the second driven member. The stop unit is connected to the second portion of the elongated rod so as to prevent axial movement of the elongated rod toward the first driven member. Rotation of the elongated rod in a first direction is converted into movement of the first driven member toward the second driven member, while rotation of the elongated rod in the opposite direction is converted into movement of the first driven member away from the second driven member.
