[0017] As shown in FIG. 1 to FIG. 4, the present invention provides a multi-point foldable dedusting duster. Adopted technical solutions are as follows: The multi-point foldable dedusting duster includes a duster fixing plate 1, the duster fixing plate 1 includes a left fixing plate 11, and a shaft sleeve 111 is disposed at a right end of the left fixing plate 11. A screw 112 is sleeved in the shaft sleeve 111, and a nut 113 is screwed at an upper end of the screw 112. The right end of the left fixing plate 11 is hinged to a left end of a right fixing plate 12, a first fixing lug 121 is fixedly connected to the middle of a rear side wall on a left side of the right fixing plate 12, and plurality of limiting grooves 122 are circumferentially arrayed on an edge on an inner side of a central hole of the first fixing lug 121. Second fixing lugs 123 are fixedly disposed on upper and lower sides of a front side wall on the left side of the right fixing plate 12 respectively, and decorative covers 124 are inserted into openings at upper and lower ends of the upper and lower second fixing lugs 123 respectively. A connecting assembly 2 is rotatably inserted into the central hole of the first fixing lug 121, the connecting assembly 2 includes a rotating shaft 21 sleeved in the central hole of the first fixing lug 121, a spring fixing cover 22 is screwed at an upper end of the rotating shaft 21 through a screw, a shaft cap 23 is fixedly connected to a lower end of the rotating shaft 21, and left and right sides of a lower half portion of the rotating shaft 21 are symmetrically provided with limiting convex blocks 24 matched with the limiting grooves 122. A spring 25 is sleeved on a rotating shaft on upper portions of the limiting convex blocks 24, an upper end of the spring 25 is fixedly inserted into a lower portion of the spring fixing cover 22, and peripheries of the spring fixing cover 22 and the shaft cap 23 are sleeved on upper and lower ends of a T-shaped connecting member 26 respectively. The upper and lower ends of the T-shaped connecting member 26 are symmetrically provided with counter bores 261, holes are formed between the upper and lower counter bores 261 in a penetrating manner, the middle of a front side wall of the T-shaped connecting member 26 is backwardly provided with a notch 262, and the rear end of the T-shaped connecting member 26 is provided with an inserting hole 263. Left and right inner side walls of the upper counter bore 261 are symmetrically provided with first inserting blocks 264, front and rear inner side walls in the lower counter bore 261 are symmetrically provided with second inserting blocks 265, left and right sides of the spring fixing cover 22 right opposite to the left and right first inserting blocks 264 are provided with first rectangular notches 221, and front and rear sides of the shaft cap 23 right opposite to the front and rear second inserting blocks 265 are symmetrically provided with second rectangular notches 231.

[0018] A working principle of the present invention is as follows: During use, a duster sleeve is sleeved on the left fixing plate 11 and the right fixing plate 12. When the left and right lengths of the duster fixing plate 1 need to be reduced, the left fixing plate 11 may be bent toward a right side to attach to a front side of the right fixing plate 12. Meanwhile, when an angle between the connecting rod 3 and the duster fixing plate 1 needs to be changed according to cleaning, a finger may be used to press the spring fixing cover 22 in the counter bore 261 at the upper end of the T-shaped connecting member 26 downwards, and the spring fixing cover 22 drives the rotating shaft 21 downward to move downward, so that the limiting convex block 24 on two sides of the rotating shaft 21 are separated from the limiting grooves 122 in the first fixing lug 121 on a rear side of the right fixing plate 12. After the limiting convex blocks 24 on the two sides of the rotating shaft 21 are inserted into the limiting notches 266 at the upper end of the counter bore 261 at the lower end of the T-shaped connecting member 26, the right fixing plate 12 may be rotated clockwise or counterclockwise as required, so that the right fixing plate and the connecting rod 3 are suspended at different angles. Then the spring fixing cover 22 is released, and under the action of the spring 25, the spring fixing cover 22 drives the rotating shaft 21 and the shaft cap 23 to move upward, so that the limiting convex blocks 24 on the two sides of the rotating shaft 21 are inserted into the limiting grooves 122 in the first fixing lug 121 again, thereby fixing the connecting rod 3 and the right fixing plate 12 at every angle.

[0019] An electrical connection manner or structure not described in detail in the specification is the prior art.
