A telescopic tube for a dust collector comprises an inner tube (1) and an outer tube. The inner tube (1) is inserted in the outer tube and capable of sliding and being positioned in the outer tube. The outer tube is formed by a first outer tube (21) and a second outer tube (22), connected through a bent mechanism. A cavity for accommodating a tube body is disposed between the first outer tube (21) and the second outer tube (22). A telescopic hose (5) is disposed in the outer tube. One end of the telescopic hose (5) is connected to the inner tube (1), and the other end thereof is connected to the second outer tube (22). When the telescopic hose (5) is located in the cavity, the first outer tube (21) and the second outer tube (22) rotate relatively through the bent mechanism. The telescopic tube for a dust collector is of a simple and compact structure and implements extension and retraction of the tube body during bending, so that the cleaning range is large and the operation is convenient. |
