Problems solved by technology

[0002] Nowadays, when most hand electric drills are drilling, it is difficult for the operator to ensure the accuracy of the drilled holes due to the vibration of the electric drill.
There have been electric hand drills with instructions to control the direction of the drill bit at present, such as the Chinese invention patent, a kind of " electric hand drill" disclosed in the specification CN2398040Y. The bulb level is set on the electric hand drill, but the vibration generated by the electric hand drill in use will be The bulb in the bulb level shakes a lot, and it is difficult for the operator to grasp the position of the bulb, which will eventually lead to low precision of the drilled hole
And the existing hand electric drill also has no indication control device when drilling the inclined hole

Embodiment Construction

[0012] like figure 1 and figure 2 As shown, an improved electric hand drill includes a casing 1, a handle 2 and a drill clamping device 3, and a pendulum-type indicator needle 4 is fixed on the casing 1 by bonding or magnetically, and the indicator needle 4 includes an indicator The disc 5 and the pointer 6 fixed on the indicating disc 5, the indicating disc 5 is provided with an indicating mark 7, and a transparent cover 8 is arranged outside the indicating pin 4, when the drill bit clamping device 3 is perpendicular to the horizontal plane, the pointer 6 is just Point to the indicator mark 7 on the indicator plate 5.

[0013] As a further improvement of the present invention, a scale is engraved on the indicating plate 5, and the indicating range of the scale is 0-90°. When drilling the inclined hole, the operator can drill the required inclined hole according to the scale pointed by the pointer 6 . Drilling is not only convenient and quick like this but also the precisi...

Abstract

The invention relates to an improved electric hand drill which comprises a shell, a handle and a drill head clamping device, wherein a guide drilling device is installed on the shell. The improved electric hand drill is characterized in that the guide drilling device is a pendulum clock type indicating pointer; the indicating pointer comprises an indicating dial and a pointer fixed on the indicating dial; an indicating mark is arranged on the indicating dial; a transparent cover is also arranged outside the indicating pointer; and when the drill head clamping device is vertical to the horizontal plane, the pointer just points to the indicating mark on the indicating dial. The invention not only has high drilling efficiency but also has high drilling accuracy.

Description

technical field [0001] The invention relates to an electric tool, in particular to an improved electric hand drill. Background technique [0002] When most of the current hand electric drills are drilling, due to the vibration of the electric drill, it is difficult for the operator to ensure the accuracy of the drilled holes. There have been electric hand drills with instructions to control the direction of the drill bit at present, such as the Chinese invention patent, a kind of " electric hand drill" disclosed in the specification CN2398040Y. The bulb level is set on the electric hand drill, but the vibration generated by the electric hand drill in use will be The ball bulb in the bulb level shakes a lot, and it is difficult for the operator to grasp the position of the bulb, which will eventually lead to low precision of the drilled hole. And existing electric hand drill also has no indicating control device when drilling inclined holes. Therefore need a kind of new tec...
