ABSTRACT:
A retaining/fixing device is disclosed. It is applicable in a container and a construction site and can be used as a jack. The retaining/fixing device mainly includes a base seat, an outer tube, an inner rod, a rack, a handle, a first claw, a second claw, a resilient plate and a stopper pin. By means of reciprocally lifting and depressing the handle, the outer tube is displaced relative to the inner rod so that the retaining/fixing device is forcedly tightened to a necessary extent. Also, the inner rod can be quickly drawn out or retracted into the outer tube.
