PURPOSE: A suction pipe of a vacuum cleaner is provided to naturally slide a slider by streamlining the configuration of an elastic restoring unit to restore the slider in the locking position. CONSTITUTION: A suction pipe of a vacuum cleaner comprises a controller(300). The controller includes a holder(310), a stopper(320), a slider(350), and a locking pin(330). The holder is installed to one side of an outer suction pipe(200) and includes a stopper insertion groove(311). The stopper is inserted into the stopper insertion groove of the holder. A lower part of the stopper is inserted into a locking groove(110) of an inner suction pipe(100) and controls the movement of the inner suction pipe. The slider is installed to the outside of the holder. A bracket(351) protruded to guide the side surface of the stopper is installed in the inside of the slider. The locking pin penetrates through the bracket of the slider. The outer circumference of the locking pin is installed to contact with the stopper. |
