[0036] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-12 As shown:

[0037] A duster that can be operated with one hand, comprising a main body, the main body comprising a handle 1 and a dust frame 3, the outer side of the dust frame 3 is provided with a dust cover 9, and preferably the outer side of the dust cover has cleaning whiskers 91; Figure 1-5 As shown, the dust removal frame 3 is provided with an extension device 4 inside. When the extension device 4 is kept in a folded state, the dust removal sleeve 9 is kept in a retracted state. Figure 7-8As shown, when the extension device 4 is deployed, it pushes the dust collection sleeve 3 to deform and maintain the extended state. The extension device 4 includes a plurality of swinging members 41 rotatably mounted on the dust collection frame. The swinging members 41 are arranged along the length of the dust collection frame. Preferably, there are at least three swinging members 41. The more swinging members, the better the support effect. The specific number is determined by the manufacturer. As shown in the figure, there are six swinging members. The swinging members 41 are connected to each other by a linkage rod 42. The plurality of swinging members 41 connected by the linkage rod 42 can rotate synchronously on the dust collection frame 3. The linkage adopts a hinged linkage. A fixed rod 31 is fixedly mounted in the middle of the dust collection frame 3. A plurality of fixed rod hinge seats 311 are provided in the longitudinal direction of the fixed rod 31. One side of the swinging member 41 is rotatably connected to the fixed rod hinge seat 311. The linkage rod 42 is provided with a linkage rod hinge seat 421. The other side of the swinging member 41 is rotatably connected to the linkage rod hinge seat 421. Preferably, some of the mounting openings of the fixed rod hinge seat face upward and some face downward; and some of the mounting openings of the linkage rod hinge seat face upward and some face downward. Preferably, the mounting openings arranged vertically are arranged in a staggered manner, with one mounting opening facing upward and the mounting openings above and / or below it facing downward. This arrangement of the mounting openings reduces the probability of the swing member detaching from the fixed rod or linkage rod, making the connection more stable. The dust removal sleeve 9 is an elastic member that rests on the swing member and / or linkage rod and imparts force to the extension device to fold.

[0038] A pusher 2 is slidingly provided on the handle 1, and the pusher 2 can be connected to the swinging member or the linkage rod; when the pusher 2 is pushed, the pusher 2 drives the swinging member or the linkage rod and causes the swinging member to rotate, thereby allowing the stretching device 4 to unfold. There are at least the following connection methods between the pusher 2 and the stretching device 4: Method 1, the connection method between the pusher and the swinging member / linking rod is abutment, and when the pusher is pushed upward, the pusher can push the swinging member / linking rod to move and unfold it. When the pusher is released, the dust cover shrinks and resets and keeps the stretching device in a folded state. Method 2, the pusher and the swinging member / linking rod are connected by a transmission rod, one end of the transmission rod is hinged to the pusher, and the other end of the transmission rod is hinged to the swinging member / linking rod. When the pusher moves upward, the stretching device is pushed to unfold, and when the pusher moves downward, the stretching device is pulled to fold. This method is similar to the unfolding structure of an umbrella. In method 3, a sliding sleeve is slidably mounted on the connecting rod 411 of the swinging member. The sliding sleeve moves along the connecting rod 411 and is hinged to a pusher. The pusher moves upward to push the extension mechanism to expand, while the pusher moves downward to pull the extension mechanism to fold. Methods 2 and 3 are not shown in the figures.

[0039] The outer side of the swinging member 41 is provided with an arcuate surface. When the swinging member is extended, the arcuate surface abuts the dust collection sleeve 9. When the extension device 4 remains extended, the arcuate surfaces of the multiple swinging members simultaneously support the dust collection sleeve 9. A linkage rod 42 is hinged to the outer side of the arcuate surface and can provide auxiliary support for the dust collection sleeve. Extension devices 4 are provided on both sides of the dust collection frame 3. The two extension devices 4 can be synchronously pushed and extended by the pusher. When the extension devices are extended, the duster takes on a cylindrical shape.

[0040] The handle 1 includes a first handle 11 and a second handle 12 fixed to each other. The second handle 12 is integrally formed with the dust collection frame 3 or fixed to the dust collection frame. The middle of the second handle 12 is penetrated, and a fixed rod 13 and a fixed rod fixing seat 131 are inserted through the lower end of the second handle 12. The pusher 2 is rotatably arranged on the outside of the fixed rod fixing seat 131 and can rotate around the fixed rod fixing seat 131. The pusher 2 abuts against the swinging member 41; when the pusher moves upward, it pushes the swinging member to expand and deform the dust collection sleeve to maintain the expanded state; when the pusher is released, the dust collection sleeve returns to its original position and drives the swinging member to rotate into the dust collection frame.

[0041] The swinging member is provided with a supporting surface, which is preferably the surface of the connecting rod 411; during the upward movement of the pushing member, the pushing member always rests against the supporting wall.

[0042] The pusher is provided with an inclined surface 22 and an end surface 23. When the extension device is folded, the inclined surface 23 of the pusher abuts against the abutment wall, with the inclined surface and the abutment wall facing each other. When the extension device is in the ultimate expansion state, the end surface 23 abuts against the abutment wall, with the end surface and the abutment wall facing each other. Both in the ultimate expansion and folded states, the abutment is face-to-face, making the structure more stable in this state.

[0043] The pusher 2 includes a limiting portion. During its upward movement, the pusher 2 can rest on the limiting portion and maintain the swinging member 41 at a specified deployment angle. The pusher 2 is rotatably mounted within the handle 1, with the upper end of the pusher extending beyond the handle and positioned below the swinging member. The pushing portion 21 of the pusher extends beyond the handle and is exposed. The handle 1 is provided with a longitudinal notch 121, with at least one resting opening 122 provided on the side of the longitudinal notch 121. The pushing portion 21 of the pusher is positioned on the longitudinal notch 121 or the resting opening 122. When the pushing portion 21 of the pusher remains on the resting opening 122, the swinging member 41 maintains the specified deployment angle. Preferably, two to three resting openings are provided to allow the duster to have multiple deployment states with different outer diameters. The limiting part can be diverse. In addition to the stop opening on the side of the longitudinal slot indicated in the accompanying drawings, it can also be an independent laterally movable component. After the component moves laterally, it blocks the bottom of the pushing part of the pushing member. Only when the component is removed can the pushing part of the pushing member move in the longitudinal slot.

[0044] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
