Vacuum cleaner

A vacuum cleaner comprising:

• a cleaner body configured to generate suction force;
• a body suction port connected to the cleaner body;
• a suction nozzle having a nozzle suction port configured to receive dust;
• a connection pipe that is disposed between the cleaner body and the suction nozzle and extends along a first direction from a first side facing the suction nozzle to a second side facing the body suction port;
• a first tool assembly detachably coupled to the body suction port, the first tool assembly having a first suction port in fluid communication with the body suction port;
• a second tool assembly detachably coupled to the first tool assembly, the second tool assembly having a second suction port in fluid communication with the first suction port;
• and
• a pipe assembly fixed to the second side of the connection pipe and detachably coupled to the second tool assembly.

A vacuum cleaner comprising:

• a cleaner body configured to generate suction force;
• a body suction port connected to the cleaner body;
• a suction nozzle having a nozzle suction port configured to receive dust;
• a connection pipe that is disposed between the cleaner body and the suction nozzle and extends along a first direction from a first side facing the suction nozzle toward a second side facing the body suction port;
• a first tool assembly comprising:
• a first body that has a pipe shape extending along the first direction and is configured to coaxially couple to the body suction port,
• a first lever that is pivotably coupled to the first body and configured to engage with and disengage from the body suction port, and
• a first rotation body and a second rotation body that are symmetrical to each other and pivotably coupled to a front portion of the first body facing away from the body suction port in the first direction, wherein the first rotation body and the second rotation body are configured to couple to each other to thereby define a first suction port;
• a second tool assembly comprising:
• a second body that has a pipe shape extending along the first direction and that is configured to coaxially couple to the first body and accommodate the first rotation body and the second rotation body, the second body having a front edge that faces away from the first tool assembly in the first direction and defines a second suction port,
• a second lever that is pivotably coupled to the second body and configured to engage with and disengage from the first body, and
• a brush coupled to the front edge of the second body;
• and
• a pipe assembly comprising:
• a third body that has a pipe shape extending along the first direction, that is coupled to a rear side of the connection pipe facing the second body, and that is configured to coaxially couple to the second body and accommodate the second body,
• a third lever that is pivotably coupled to the third body and configured to engage with or disengage from the second body,
• a first tool button that is configured to rotate the second lever to thereby disengage the second lever from the first body, and
• a second tool button that is configured to rotate the third lever to thereby disengage the third lever from the second body.
