Abstract

The invention relates to an adjusting device for an electric impact drill. The adjusting device comprises a gear case front shell, a torsion cover rotationally arranged on the top of the gear case front shell in a sleeving manner, a speed reduction mechanism arranged at the bottom of the gear case front shell, and a gear skipping structure arranged in the torsion cover. The gear skipping structure comprises an adjusting screw, a gear skipping gasket, an adjusting ring and an impact conversion gasket. The adjusting ring has the locking function on the gear skipping gasket and the impact conversion gasket. The torsion cover is provided with an upper boss, the adjusting ring is provided with a lower boss, the upper boss corresponds to the lower boss, and therefore when the torsion cover rotates anticlockwise, the adjusting ring is driven to rotate, and when the torsion cover rotates clockwise, the adjusting ring does not rotate; and in the adjusting ring rotating process, the locking function on the gear skipping gasket and the impact conversion gasket can be switched, switching of electric drill gears can be achieved, and therefore the gear switching can be achieved only through anticlockwise rotation of the torsion cover, and the effects of the short adjusting stroke and fast switching are achieved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a gear adjustment device for an impact electric drill. Background technique [0002] The impact electric drill is a commonly used decoration electric tool. For the convenience of use, there are usually three gears: the screw gear, the electric drill gear and the impact gear. The adjustment of the three gears usually changes the torque of the internal structure of the inner drill. The most commonly used method is to rotate the torque cap to adjust the torque and whether to skip gears. However, in the adjustment process of the existing impact electric drill, the torque cap of the torque cap is too far away, so that the user sometimes fails to adjust it in place due to insufficient torque during use. And affect the quality of work and speed of work, and also bring potential safety hazards during use. Contents of the invention [0003] The object of the present invention is...
