ABSTRACT:
A motor-driven vehicle includes a first vehicle body with a sleeve tube, a second vehicle body with an insert rod disposed telescopically within the sleeve tube, and a locking device including a pull rod, a retaining block and a resilient member. The pull rod is movable on the first vehicle body between a locking position and a release position. When the pull rod is disposed at the locking position, the retaining block extends through a hole in the sleeve tube and engages a selected one of holes in the insert tube of the second vehicle body. When the pull rod is disposed at the release position, the retaining block is removed from the holes in the insert rod. The resilient member biases the pull rod to the locking position.
