[0017] In the description of the utility model, it needs to be explained that the orientation or position relation indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is the orientation or position relation based on the drawing shown, and is only for the convenience of describing the utility model and simplifying the description, and cannot be understood as the limitation on the utility model that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation.

[0018] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, can be fixed connection, can be detachable connection, or integrally connected;Can be mechanical connection, can be electrical connection;Can be directly connected, can be indirectly connected through an intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0019] For example, Figures 1-4As shown, a pole-mounted locking mechanism for a handheld sweeper includes an upper connector 1, a lower connector 2, a locking cover 3, a locking block 4, and a spring 5. The upper connector 1 is installed below the pole A of the sweeper, and the lower connector 2 is installed above the floor brush B of the sweeper. The locking cover 3 is installed in front of the lower connector 2. A groove 6 is formed between the inner wall of the locking cover 3 and the lower connector 2. The locking block 4 and the spring 5 are installed in the groove 6. The upper end of the spring 5 abuts against the locking block 4, and the lower end abuts against the inner wall of the groove 6. The bottom of the upper connector 1 is provided with a locking groove 7 corresponding to the position of the locking block 4. The locking groove 7 is vertically arranged. When the pole A is upright, the upper connector 1 is also upright. When the upper connector 1 is upright, the spring 5 drives the locking block 4 to extend upward into the locking groove 7, thereby locking the pole A in the upright position.

[0020] like Figure 3 As shown, the upright locking mechanism of the rod also includes a connecting plate 8 and a rotating shaft 9. The connecting plate 8 has two pieces that are fixedly inserted into the front and rear sides of the lower connector 2. The upper connector 1 has a transition part 10 on the front and rear sides of its lower end. The transition part 10 has a through hole 11. The rotating shaft 9 is placed in the through hole 11. The rotating shaft 9 and the through hole 11 are in clearance fit. The rod of the rotating shaft 9 passes through the through hole 11 and connects to the connecting plate 8. The locking groove 7 is located at the middle of the bottom of the transition part 10 on the front side. The upper connector 1 and the lower connector 2 can rotate relative to each other through the cooperation of the connecting plate 8 and the rotating shaft 9.
