Document Type and Number:
WIPO Patent Application WO/2021/182771
Kind Code:
A1
Abstract:
A vacuum cleaner comprises: a first pipe having an engaging groove formed at one side thereof; a second pipe which communicates with the first pipe and into which one side of the first pipe is inserted; and a selective locking part provided to selectively restrict the movement of the first pipe and the second pipe relative to each other while the first pipe is inserted in the second pipe, wherein the selective locking part comprises: an engaging member having a shape corresponding to the engaging groove, and capable of moving in a first direction to be received in the engaging groove, or a second direction opposite thereto; an elastic member for elastically pressing the engaging member in the first direction; a manipulation portion provided at the outside of the second pipe and capable of moving between a first position in which an external force is applied and a second position in which the external force is released; and multiple transfer members arranged to be spaced apart from each other in multiple positions so as to transfer the external force applied to the manipulation portion to the engaging member. As the manipulation portion moves from the second position to the first position, the engaging member received in the engaging groove is moved in the second direction and disengaged from the engaging groove by the multiple transfer members.
