[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] Figures 1-5 As shown, an electric drill with a dust cover includes a body 1 and a drill bit 7 disposed on the body 1. A dust cover 2 is detachably connected to the body 1 and fitted over the drill bit 7.

[0026] Figures 1-5 As shown, by setting up a dust cover 2, the drill bit 7 can be covered when the electric drill is used. At this time, the dust generated by the electric drill can be blocked inside the dust cover 2, thereby achieving the function of dust prevention and avoiding dust from flying and polluting the environment and harming the health of the staff. At the same time, since the diameter of the dust cover gradually increases from the end closer to the machine body 1 to the end farther away from the machine body 1, the coverage area of ​​the dust cover 2 can be expanded and the dust prevention effect can be improved.

[0027] Figures 1-5 As shown, the dust cover 2 is made of a transparent material, such as an acrylic sheet, which allows for easy observation of the use of the drill bit 7.

[0028] Figures 1-5As shown, the dust cover 2 includes several movable pieces 201, which are slidably connected to each other. Each movable piece 201 has a groove 4 on its outer side wall and a slider 6 is fixedly connected to its inner side wall. When the movable piece 201 slides, the slider 6 slides in the groove 4 corresponding to it.

[0029] Figures 1-5 As shown, when using drill bit 7, as drill bit 7 gradually penetrates into the wall, the movable piece 201 with the largest diameter slides under the push of the wall. At this time, slider 6 slides in the groove 4, thereby limiting the sliding trajectory of movable piece 201. At the same time, dust cover 2 retracts, which facilitates the use of drill bit 7. This design allows the dot not only to be used normally but also to have a dustproof effect.

[0030] Figures 1-5 As shown, each slider 6 is hinged with a connecting rod 8. One end of the connecting rod 8 is rotatably connected to the movable plate 201. When the movable plate 201 slides, the slider 6 slides in the groove 4 and the connecting rod 8 rotates.

[0031] Figures 1-5 As shown, when the movable piece 201 slides, the distance between two adjacent movable pieces 201 gradually increases as it contracts. At this time, the connecting rod 8 connects the movable piece 201 and the slider 6. As the movable piece 201 slides, the connecting rod 8 rotates, which facilitates the sliding of the movable piece 201. This design connects the movable piece 201 and the slider 6, making it easier for the movable piece 201 to slide.

[0032] Figures 1-5 As shown, a slide rail 9 is fixedly connected inside the slide groove 4, and the slider 6 slides on the slide rail 9. This design not only limits the sliding range of the slider 6, but also effectively prevents the slider 6 from separating from the slide groove 4 when sliding, ensuring the normal contraction of the dust cover 2.

[0033] Figures 1-5 As shown, a spring 5 is fixedly connected between the slider 6 and the slide 4. When the movable piece 201 slides, the spring 5 deforms. When the electric drill is used up and separated from the wall, the deformed spring 5 pushes the slider 6 and the movable piece 201 to return to their original positions, thus facilitating the next use.

[0034] Figures 1-5 As shown, the dust cover 2 is provided with several locking blocks 11, and the machine body 1 is provided with several slots 10 for easy locking of the locking blocks 11. When the locking blocks 11 are locked into the slots 10, the dust cover 2 is fixed to the machine body 1. When it is necessary to replace the dust cover 2 or clean the dust inside the dust cover 2, the locking blocks 11 are separated from the slots 10 by moving the dust cover 2 housing, thereby removing the dust cover 2. This design facilitates the fixing and disassembly of the dust cover 2.

[0035] Figures 1-5 As shown, the card block 11 has an arc-shaped surface, which facilitates the card block 11 to be inserted into or separated from the card slot 10.

[0036] Figures 1-5 As shown, a dustproof sheet 3 is fixedly connected inside the dust cover 2. The dustproof sheet 3 is elastic. When the spring 5 is in its natural state, the dust cover 2 is in the unfolded state and the dustproof sheet 3 is taut. By setting the dustproof sheet 3, dust can be further isolated, preventing dust from leaking out through the gap between two adjacent movable sheets 201. This design further improves the dustproof effect of the dust cover 2.

[0037] Figures 1-5 As shown, there is a gap between the dust cover 3 and the dust cover 2. When the dust cover 2 is in the unfolded state, the dust cover 3 fits against the inner wall of the dust cover 2. This design allows the dust cover 3 to move freely when the dust cover 2 is unfolded, making it easier for it to deform.

[0038] The above describes an electric drill with a dust cover provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
