However, during the drilling operation, dust often falls off and flies, which can easily affect the indoor air quality and thus affect the health of on-site personnel. Subsequent maintenance and cleaning are required, which is very laborious.

[0003] Upon investigation, a Chinese patent discloses a dustproof mechanism for an electric drill (publication number: CN205111788U), including a dust cover, a corrugated telescopic tube and a connector for connecting to the outer casing of an electric drill, the dust cover including a dust cover body, an outer port and an inner port are formed at two ends of the dust cover body respectively, the dust cover body is stretched radially outward to form a dust storage portion with a pocket-shaped structure, and the dust storage portion is arranged around the circumference of the dust cover body; the dustproof mechanism for an electric drill also includes a compression spring sleeved on the corrugated telescopic tube; the dust cover body is provided with a pocket-shaped dust storage portion for storing dust.

[0004] The above patent not only has a good dust-proof effect, but also at the end of drilling, dust is not easy to slip out of the dust cover and cause flying. A compression spring is provided. During the drilling process, the electric drill presses the connecting head, so that the compression spring presses the dust cover, so that the outer port of the dust cover is tightly pressed against the wall to form a seal. However, this device will block the electric drill head, making it inconvenient to observe the drilling degree and condition of the electric drill in real time, which may lead to inaccurate drilling and affect the quality of subsequent construction or assembly.

[0005] Therefore, the utility model provides a dustproof mechanism for an electric drill to solve the above problems. Utility Model Content

[0011] A further improvement of the technical solution of the present utility model lies in that the connection component includes an extension plate. The front surface of the extension plate is fixedly connected to one end of the telescopic rod. A positioning ring is fixedly connected to one side of the extension plate. A rubber sleeve is fixedly connected to the back surface of the positioning ring.

[0012] A further improvement of the technical solution of the present utility model lies in that a clamping ring is fixedly connected to one side of the outer surface of the housing. An anti-slip pad is fixedly connected to the inside of the clamping ring.

[0013] A further improvement of the technical solution of the present utility model lies in that an air outlet is formed at the edge of the outer surface of the housing. A through groove is formed on the front surface of the mounting plate around the driving motor.

[0024] Referring to Figures 1 - 5 , the present utility model provides three technical solutions:

[0025] Embodiment 1:

[0026] A dust-proof mechanism for an electric drill includes an absorption component. The front surface of the absorption component is connected by bolts in a threaded manner to a collection component. One end of the collection component is fixedly connected to an expansion component, and one end of the back surface of the expansion component is fixedly connected to a connection component;

[0027] The expansion component includes a collection box 1. The upper surface of the collection box 1 is fixedly connected to one end of the collection component. The back surface of the collection box 1 is fixedly connected to a telescopic rod 2. The collection box 1 is supported by the telescopic rod 2. During the drilling process, the extension plate 11 squeezes the spring 3. The spring 3 contracts and at the same time forms a rebounding force, pushing the collection box 1 against the wall tightly. And the number of the collection boxes 1 is two, which are respectively located on the upper and lower sides of the drilling position, can collect the fallen dust and the flying dust, improve the dust-proof effect, and there is no blockage to the electric drill bit, facilitating the real-time observation of the drilling depth and condition of the electric drill, and avoiding inaccurate drilling, which affects the quality of subsequent construction or assembly.

[0028] Embodiment 2:

[0029] Based on Embodiment 1:

[0030] The absorption assembly includes a housing 4. The front surface of the housing 4 is connected to the back surface of the collection assembly by bolt threading. A mounting plate 5 is fixedly connected to the inner side wall of the housing 4. A driving motor 6 is fixedly connected to the front surface of the mounting plate 5. The output end of the driving motor 6 is fixedly connected to a fan blade 7. Starting the driving motor 6 drives the fan blade 7 to rotate, which is convenient for creating a negative pressure inside the sealing cover 8 to generate suction, thereby absorbing dust.

[0031] The collection assembly includes a sealing cover 8. The back surface of the sealing cover 8 is connected to the front surface of the housing 4 by bolt threading. A dust-proof bag 9 is arranged inside the sealing cover 8. Air inlets are formed on both sides of the outer surface of the dust-proof bag 9. An air inlet pipe 10 is inserted into the air inlets. Under the action of the absorption assembly, a negative pressure is formed inside the sealing cover 8, and then the dust is absorbed into the dust-proof bag 9 through the air inlet pipe 10, thereby collecting the dust and preventing it from affecting the indoor environment. Moreover, the sealing cover 8 and the housing 4 are connected by bolt threading. Unscrewing the bolts can separate the two, facilitating the removal of the dust-proof bag 9 for replacement for the next use.

[0032] The connection assembly includes an extension plate 11. The front surface of the extension plate 11 is fixedly connected to one end of the telescopic rod 2. A positioning ring 12 is fixedly connected to one side of the extension plate 11. A rubber sleeve 13 is fixedly connected to the back surface of the positioning ring 12. The rubber sleeve 13 is expandable. Pass the rubber sleeve 13 through the drill bit and socket it to the head of the electric drill, so that the positioning ring 12 is in a suitable position. The positioning ring 12 increases the bearing force at the socketing part. The extension plate 11 extends upward and downward, so that the collection box 1 is located on the upper and lower sides of the drilling position, thereby connecting the expansion assembly to the electric drill. The operation is convenient and beneficial for use.

[0033] A snap ring 14 is fixedly connected to one side of the outer surface of the housing 4. An anti-slip pad 15 is fixedly connected to the inner side of the snap ring 14.

[0034] An air outlet is formed at the edge of the outer surface of the housing 4. A through groove is formed on the front surface of the mounting plate 5 around the driving motor 6. The through groove and the air outlet facilitate the outflow of the air entering through the air inlet pipe 10.

[0035] Embodiment 3:

[0036] Based on Embodiments 1 and 2:

[0037] First, pass the rubber sleeve 13 through the drill bit and socket it to the head of the electric drill. The positioning ring 12 increases the bearing capacity at the socket. The extension plate 11 extends upward and downward, so that the collection box 1 is located on the upper and lower sides of the drilling area. Then, snap the snap ring 14 onto the upper part of the electric drill. The anti-slip pad 15 increases the friction force, making the connection of the snap ring 14 more stable, thereby fixing the positions of the collection component and the absorption component. Secondly, during the drilling process, the extension plate 11 squeezes the spring 3. The spring 3 forms a rebound force, pushing the collection box 1 against the wall and being located on the upper and lower sides of the drilling area. At the same time, start the drive motor 6 to drive the fan blade 7 to rotate, creating a negative pressure inside the sealing cover 8. The dust is absorbed into the dust-proof bag 9 through the air inlet pipe 10 to collect the falling dust and the floating dust. Finally, rotate the bolt in a threaded manner to separate the sealing cover 8 from the housing 4, and the dust-proof bag 9 can be taken out for replacement for the next use.
