In this embodiment, when working with the present aluminum alloy hand drill, the worker first installs the bearing 4 in the drill bit 3 and ensures that the bearing 4 can freely rotate. Then, the aluminum alloy body 2 is installed in the bearing 4 such that the outer surface of one end thereof is fixedly coupled to the inner surface of the bearing 4. Next, the magnet 5 is mounted at the end of the aluminum alloy drilling body 2 away from the bearing 4, and one end thereof is fixedly connected to the aluminum alloy drilling body 2. Then, the four-jaw chuck 6 is mounted on the outer surface of the magnet 5, and the drill bit 7 is fixed in the four-jaw chuck 6 by nesting. Finally, an aluminum alloy knob 1 is arranged on the outer surface of the four-jaw chuck 6, and one end of the aluminum alloy knob is fixed at one end of the aluminum alloy drilling body 2 far away from the bearing 4 in a threaded rotation mode. Thus, the aluminum alloy hand drill is assembled. When the hand drill is used, a user can control the position and depth of the drill bit 7 by rotating the aluminum alloy knob 1 so as to complete the task of drilling or perforating. Because the hand drill adopts the high-strength and corrosion-resistant aluminum alloy material, the hand drill has longer service life and good durability, and compared with the traditional aluminum alloy hand drill, the hand drill has simple shape in the use process, the drill bit 7 is not protected, is positioned outside the device for a long time, and the drill bit 7 is in an exposed state for a long time, so that the drill bit 7 can be possibly damaged.

Working principle:

as shown in fig. 1-3, first, it is necessary to install the bearing 4 in the drill bit 3 and ensure that the bearing 4 can rotate freely. Thus, the drill bit 7 can be rotated stably, and no jamming or deviation can occur. Next, the aluminum alloy drill body 2 is mounted in the bearing 4 such that the outer surface of one end thereof is fixedly connected to the inner surface of the bearing 4. Therefore, the firm connection between the aluminum alloy drilling body 2 and the bearing 4 can be ensured, and the loosening or falling-off condition can not occur. Then, a magnet 5 is installed at one end of the aluminum alloy drilling body 2 away from the bearing 4, and one end thereof is fixedly connected to the aluminum alloy drilling body 2. Therefore, the firm connection between the magnet 5 and the aluminum alloy drilling body 2 can be ensured, and the loosening or falling-off condition can not occur. Next, the four-jaw chuck 6 is mounted on the outer surface of the magnet 5, and the drill bit 7 is fixed in the four-jaw chuck 6 by a nesting manner. In this way, the firm connection between the drill bit 7 and the four-jaw chuck 6 can be ensured, and the situation of falling off or deviation can not occur. Finally, an aluminum alloy knob 1 is arranged on the outer surface of the four-jaw chuck 6, and one end of the aluminum alloy knob is fixed at one end of the aluminum alloy drilling body 2 far away from the bearing 4 in a threaded rotation mode. This allows the user to control the position and depth of the drill bit 7 by rotating the aluminum alloy knob 1 to perform the drilling or perforating task.
