ABSTRACT:
The present invention relates to a push button type pull rod control structure, i.e. to locate an adjustable length pull rod of a trunk. The control structure has a push button, a pull rod, a push rod, an outer rod, a sleeve, a control body, and a spring. A distal end of the pull rod has the sleeve, which includes an extensible control body. The control body, the push rod and it push button are connected to one another. Pushing the push button enables locating balls to move back into control body groove seat so as not to project into location holes of the outer rod to enable the length of the pull rod to be adjusted until the locating balls are aligned with other location holes on the outer rod. Releasing the push button enables the locating balls to project into other location holes, to hold the pull rod in its adjusted position.
