[0018] Below is a combination of the embodiments and the attached Figures 1 to 3 , the technical solution of the utility model is further elaborated.
[0019] Example 1
[0020] A vacuum cleaner impeller, comprising: an upper cover 1, a lower cover 2, a blade 3, a locking sleeve 4, a plug rod 5, a rotating shaft 6, a bolt 7, a support block 8 and a locking bolt 9, wherein the blade 3 is integrally formed and connected to the upper end of the lower cover 2, a through hole 10 is provided between the upper cover 1 and the lower cover 2, the plug rod 5 is inserted into the through hole 10, a through hole 2 11 is provided inside the plug rod 5, a clamping block 12 is provided at the upper end of the plug rod 5, and a groove 1 is provided at the side end ring of the plug rod 5 3, the upper cover 1 is arranged on the upper end surface of the lower cover 2, the locking sleeve 4 is sleeved on the insertion rod 5 and the clamping block 12 is clamped in the clamping groove 14 inside the locking sleeve 4, the support block 8 is sleeved on the insertion rod 5 and is located between the locking sleeve 4 and the upper cover 1, the locking bolt 9 is threadedly connected to the lower cover 2 and the upper cover 1 in sequence and the upper end supports the support block 8, the rotating shaft 6 is arranged through the second through hole 11, and the bolt 7 is threadedly connected to the rotating shaft 6 and is located on the upper end surface of the locking sleeve 4.
[0021] like Figure 1 to Figure 3 As shown, the use principle of the utility model is as follows: after the upper cover 1 is placed on the upper end of the lower cover 2, the plug rod 5 is passed through the through hole 10 and the supporting block 8, and the clamping block 12 and the plug rod 5 body are retracted until they are located at the upper end of the upper cover 1. After that, the plug rod 5 and the clamping block 12 are reset and rebounded, and the locking sleeve 4 is pressed down and sleeved on the upper end of the plug rod 5 to push the clamping block 12 on the plug rod 5 to retract until the clamping block 12 is clamped into the clamping groove 14 of the locking sleeve 4, and the locking bolt 9 is rotated to push the supporting block 8 to move upward and push the locking sleeve 4 to move upward, so that the locking sleeve 4 is against the clamping block 12, and then the rotating shaft 6 is inserted into the through hole 2 11 of the plug rod 5 and the bolt 7 is screwed in. The insertion of the rotating shaft 6 into the through hole 2 11 can prevent the plug rod 5 and the clamping block 12 from shrinking inward, thereby ensuring that the clamping block 12 and the locking sleeve 4 are stably clamped, thereby preventing the upper cover and the lower cover from loosening.
[0022] When disassembly is required, first take out the rotating shaft 6, unscrew the locking bolt 9, and then move the supporting block 8 and the locking sleeve 4 downward. At this time, the clamping block 12 at the upper end of the insertion rod 5 is located above the locking sleeve 4.
