[0024] Please refer to Figures 1 - 5 , an embodiment provided by the present utility model: A multi-angle foldable dust brush, including a handle 1 and a hair fork 2 arranged at the front end of the handle 1. A connecting block 4 is arranged at the center position of the front end face of the handle 1, and horizontal rotating shafts 5 are installed on both sides of the connecting block 4. Rotating rings 3 are arranged on both sides of the rear end of the hair fork 2, and the rotating rings 3 are sleeved on the outer ends of the rotating shafts 5. A limiting and fixing assembly is connected between the rotating ring 3 and the handle 1;
[0025] The limiting and fixing assembly includes card blocks 8 installed at equal intervals on the outer side surface of the rotating ring 3, and a locking stop bar 6 connected to the front end face of the connecting rod 101. Card slots 7 are opened at equal intervals at the top end of the locking stop bar 6. When a plurality of card blocks 8 are respectively snapped into the interiors of the card slots 7, the handle 1 and the hair fork 2 are horizontally unfolded;
[0026] The cross-section of the card block 8 is triangular, and the end of the triangle is curved. The abutting side of the card block 8 and the card slot 7 is of frosted texture;
[0027] The hair fork 2 is rotatably connected to the connecting rod 101 through the cooperation of the rotating ring 3 and the rotating shaft 5. When different card blocks 8 are snapped into the interiors of the card slots 7, the hair fork 2 and the handle 1 form folds at different angles;
[0028] The clamping blocks 8 are annularly distributed on the rotating ring 3, and the distribution length of the multiple clamping blocks 8 accounts for one-fourth of the outer ring of the rotating ring 3. The clamping blocks 8, the rotating ring 3 and the hair fork 2 are of an integral structure;
[0029] The connecting rod 101, the connecting block 4, the locking bar 6 and the clamping groove 7 are of an integral structure;
[0030] Specifically, as Figure 1 、 Figure 2 and Figure 3 、 Figure 5 shown, during use, the cooperation between the clamping groove 7 and the clamping block 8 is utilized to fix the rotation angle of the hair fork 2, improve the contact area between the rotating ring 3 and the connecting rod 101, and utilize the clamping effect of the clamping groove 7 and the clamping block 8 to prevent the hair fork 2 from folding randomly;
[0031] The rear end of the grip rod 102 is connected with multiple extension rods 104, and the grip rod 102 and the extension rods 104 are threadedly connected through the threaded rod 103. The threaded rod 103 is respectively arranged at the rear ends of the grip rod 102 and the extension rods 104. The rear end of the extension rod 104 at the end is connected with a tail cone 105 through the threaded rod 103. By adding multiple extension rods 104 between the tail cone 105 and the grip rod 102, the use length of the entire dust removal duster is extended;
[0032] The front end of the connecting rod 101 is in a quarter-circular arc shape, and the limit fixing component is arranged on the left and right sides of the inner end face of the arc;
[0033] Specifically, as Figure 1 、 Figure 4 shown, during use, the structure such as the connecting rod 101 is utilized to facilitate the folding of the hair fork 2, thereby reducing the occupied space of this dust removal duster.
[0034] Working principle: When the utility model is in use, first, through the threaded rod 103, the grip rod 102 is sleeved and screwed on the outside of the threaded rod 103, so as to extend the overall length of the handle 1, so as to facilitate the cleaning of higher positions by this dust removal duster;
[0035] Secondly, by moving the hair fork 2 inward, the rotating ring 3 rotates along the rotating shaft 5, causing the clamping block 8 to undergo a slight deformation, and then the clamping block 8 moves from the original position of the clamping groove 7 to the next clamping groove 7. The clamping between the clamping groove 7 and the clamping block 8 is utilized to fix the rotating ring 3, thereby preventing the hair fork 2 from moving randomly. And when the hair fork 2 is folded to coincide with the handle 1, the clamping block 8 is completely separated from the clamping groove 7, so that the entire dust removal duster is folded to reduce the occupied space.
