In the embodiment of the present application, the depth of the rigid rod 40 extending into the elastic tube 30 is not limited, and the rigid rod can extend completely into the lowest end of the elastic tube 30 to completely limit the bending performance of the elastic tube 30; or the cleaning head 20 does not extend into the elastic tube 30 completely, and a certain height is reserved between the cleaning head and the elastic tube 30 at the lowest end, so that the elastic tube 30 still has certain bending capability, but the bending amplitude is limited, and the swinging amplitude of the cleaning head 20 relative to the cleaning handle 10 can be adjusted. By the design, the user can adjust the depth of the rigid rod 40 extending into the elastic pipe fitting 30 according to the use habit or the use requirement of the user, the flexibility is higher, and the personalized use requirement of the user is met.

Alternatively, a rigid rod 40 is movably disposed in the sweeper handle 10, and the rigid rod 40 can move up and down along the axial direction of the sweeper handle 10 to extend into or out of the elastic tube 30.

The broom handle 10 is a hollow tubular structure, a containing space is provided for arranging the rigid rod 40, the lower end part of the broom handle 10 is connected with the elastic pipe fitting 30, the rigid rod 40 is arranged at the lower part of the broom handle 10, and the rigid rod 40 can conveniently move downwards from the inside of the broom handle 10 to extend into the elastic pipe fitting 30 or move upwards to leave the elastic pipe fitting 30 to enter the inside of the broom handle 10.

In the embodiment of the present application, the handle 10 is provided with a holding portion for moving the rigid rod 40 up and down along the axial direction of the handle 10.

The rigid rod 40 is disposed inside the broom handle 10, and it is inconvenient for a user to directly hold the rigid rod 40 to control whether the rigid rod 40 is inserted into the elastic tube member 30. Through setting up the portion of gripping, this portion of gripping can be connected and then drive the removal of rigid rod 40 with rigid rod 40 transmission, and the user can come the reciprocating of control rigid rod 40 through the portion of gripping, and convenience of customers adjusts the position of rigid rod 40.

In the process of moving the holding part in the vertical groove 111, the left and right opposite groove walls of the vertical groove 111 have a limiting effect on the holding part, so that the position of the holding part can be prevented from shifting, and the rigid rod 40 can be prevented from contacting the inner wall of the broom handle 10 or the inner surface of the elastic pipe fitting 30 in the up-and-down moving process, the operation of a user is blocked, and poor use experience is brought.

Further, as shown in fig. 1 and 2, the side wall of the sweep handle 10 is further provided with a lateral groove 112 communicating with the vertical groove 111, and a groove wall of the lateral groove 112 is used for abutting against the grip portion to position the rigid rod 40.

Illustratively, as shown in fig. 1, the horizontal slot 112 may communicate with the lower end (the end relatively close to the cleaning head 20) of the vertical slot 111, and the horizontal slot 112 and the vertical slot 111 communicating with each other form the sliding slot 11 of an "L" shaped structure for the grip portion to slide inside. When the holding part is positioned in the vertical groove 111, the holding part can move up and down to control the rigid rod 40 to move up and down, and when the holding part is positioned at the top end (the uppermost end) of the vertical groove 111, the rigid rod 40 leaves the elastic pipe fitting 30; when the holding portion is located in the transverse groove 112, the rigid rod 40 extends into the elastic tube 30, and the groove wall of the transverse groove 112 abuts against the holding portion, so that the holding portion cannot move in the axial direction of the sweep handle 10, and the position of the rigid rod 40 is fixed.
