A hand-held drilling machine using a cross structure to prevent crookedness

Abstract

The invention discloses a handheld drilling machine for preventing skew by utilizing a cross-shaped structure. The handheld drilling machine for preventing skew by utilizing the cross-shaped structurestructurally comprises a drilling machine body, a control grip, a balance handle, a cross-shaped skew-preventing device, a drill bit installation hole and a drilling bit, wherein the control grip isarranged on the lower back part of the drilling machine body so as to form an integrated forming structure; the control grip is electrically connected with the drilling machine body; and the balance handle is arranged on the lower front part of the drilling machine body and is spirally and perpendicularly connected with the drilling machine body. According to the handheld drilling machine for preventing skew by utilizing the cross-shaped structure provided by the invention, through the cross-shaped skew-preventing device, by utilizing the cross-shaped structure, under the cooperation of a triangular stable structure, the handheld drilling machine is assisted in perpendicularly drilingl a hole, so that the occurrence of the phenomenon that a finished hole is inclined due to nonuniformity ofthe hand control force and slight angle deviation is prevented, and normal drilling is ensured.

Description

technical field [0001] The invention relates to the field of drilling machines, more precisely, it is a hand-held drilling machine which utilizes a cross structure to prevent crookedness. Background technique [0002] A hand-held drilling machine refers to a machine that leaves a hole on a target by rotating a tool that is harder and sharper than the target by hand, and is widely used in life. But there is following defect in the hand-held drilling machine of prior art; [0003] Due to the need for drilling depth, the drill needle is usually long. When performing hand-held drilling, the uneven force of the hand control and slight deviation of the angle will often cause the drilled hole to be inclined, which cannot meet the actual demand. , or the screw cannot be screwed in normally later. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a hand-held drilling machine that uses a cross structur...
