[0022] Furthermore, the guide assembly 201 includes a positioning plate 2011, with a positioning groove 2014 extending through the center of the positioning plate 2011. Fixing plates 2012 are integrally formed at both ends of the side of the positioning plate 2011 away from the centering assembly 202. An extension plate 2013 is integrally formed at the outer end of the fixing plate 2012 away from the positioning plate 2011. A through hole 2017 extends through the center of the extension plate 2013. A through groove 2015 extends through the center of the fixing plate 2012. A scale is provided at the bottom outer end of the fixing plate 2012. Mounting holes 2016 are symmetrically formed through the outer end of the fixing plate 2012 away from the positioning plate 2011. The fixing plate 2012 is fixedly connected to one side of the electric drill body 1 through the mounting holes 2016 and bolts.

[0023] The centering assembly 202 includes a centering plate 2021. A slot 2023 is formed through the middle of the centering plate 2021. Sliding plates 2022 are integrally formed at both ends of the side of the centering plate 2021 closest to the guide assembly 201. The sliding plates 2022 movably pass through the interior of a limiting rod 2024. Sliding grooves 2026 are formed through the top and bottom ends of one side of the sliding plates 2022. A limiting rod 2024 is integrally formed at the end of the sliding plate 2022 furthest from the centering plate 2021. A return spring 2025 is movably sleeved on the limiting rod 2024, with both ends of the return spring 2025 respectively connected to the sliding plate 2022. One end of the device is fixedly connected to one side of the extension plate 2013. With the setting of the positioning component 2, when drilling, the electric drill body 1 can be straightened by the straightener assembly 202 and the dust collection cover assembly 203 being attached to the metal surface. The sliding plate 2022 is limited by the fixed cover 204, and the limiting rod 2024 is limited by the through hole 2017. The double limiting setting ensures that the electric drill body 1 drills in a straight line without tilting, which facilitates drilling and improves the aesthetics of the drilling.

[0025] Working principle of this utility model:

[0026] During drilling, the dust cover assembly 203 is first placed against the metal surface. At this time, the front end of the drill bit on the drill body 1 is also against the metal surface. Drilling then begins. The switch on the drill body 1 is pressed to start drilling, and the drill body 1 is pushed downwards. Simultaneously, the dust cover assembly 203 and the stabilizer assembly 202 slide in opposite directions. As the stabilizer assembly 202 slides, it compresses the two return springs 2025. The limit rod 2024 slides inside the through hole 2017, and the sliding plate 2022 slides inside the fixed cover 204. While sliding, the front end of the sliding plate 2022 corresponds to the scale, making it easy to observe the drilling depth. After drilling is completed, the drill body 1 is removed, the return springs 2025 return to their original deformation, and the stabilizer assembly 202 and the dust cover assembly 203 are pushed back to their initial positions.
