ABSTRACT:
An improved pull handle for use on a trunk is equipped with a pair of driving rods each having a wedge member disposed at the bottom end thereof which is in abutment with a spring biased locking seat having an oblique cam surface. Each driving rod is housed in a hollow tube and the locking seat is in selective engagement with one of a plurality of spaced retaining slots disposed on a movable sleeve which accommodates each hollow tube. A pressing button housed in the handle embodiment of the pull handle with a part thereof exposed externally for hand operation is in engagement with both ends of a pair of pivot levers which are pivotally fixed at the center thereof to the handle embodiment respectively. The other ends of the pivot levers are engaged with the driving rods at the opposite end thereof whereby the actuation of the pressing button will drive simultaneously both the driving rods to free the two sleeves so as to permit the sleeves to extend or retract and relock the same in place after the length of the pull handle is varied,
