Problems solved by technology
Since this kind of drilling tool relies on hand-held operations, it often encounters the situation of drilling deviation due to unstable hand-holding during use
Once the drilling is deviated, the drill bit will be stuck if it is mild, and the drill pipe will break if it is serious, causing equipment damage
As a result, drilling jobs can be difficult for someone who doesn't use a handheld drill very often

The invention discloses a hand drill deviation prevention device capable of adjusting a drilling angle. The hand drill deviation prevention device comprises a guide sleeve and a fixed sleeve which is arranged on a hand drill, wherein the inner wall of the guide sleeve is provided with a guide strip; the outer wall of the fixed sleeve is provided with a guide groove; the outer wall of the guide sleeve is provided with three deviation prevention supporting legs; one end of each of the deviation prevention supporting legs is hinged with the guide sleeve; the deviation prevention supporting legs are provided with angle adjusting rods; one end of each angle adjusting rod is connected with each deviation prevention supporting leg through a rotating shaft, and the other end of each angle adjusting rod is connected with a sliding rod in a guide sleeve sliding chute; a positioning block is also arranged in the deviation prevention device and is provided with a clamping groove; the width of the clamping groove is equal to the width of the angle adjusting rod; a positioning clamping hole is formed in the clamping groove; and matched clamping teeth are arranged in the positioning clamping hole and on the surface of the rotating shaft. During drilling operation, the guide sleeve is kept fixed by means of a supporting effect of the deviation prevention supporting legs, and the axial direction of the guide sleeve faces towards the drilling direction all the time. The hand drill faces towards the drilling direction all the time through guide action of the guide sleeve and the fixed sleeve, the drilling direction is kept unchanged, and the deviation is prevented.
Description
technical field [0001] The invention relates to a hand-held electric drill, in particular to a hand-drill anti-deviation device capable of adjusting the drilling angle. Background technique [0002] Hand-held electric drills are tools that people often use in production and life, such as drilling installation holes on walls or equipment. Because this kind of drilling tool relies on hand-held operations, it often encounters the situation that the drilling is deviated due to unstable hand-holding during use. Once the drilling is deviated, the drill bit will be stuck if it is light, and the drill pipe will break if it is serious, causing equipment damage. As a result, drilling jobs can be difficult for someone who doesn't use a handheld drill very often. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand drill anti-deviation device that can adjust the drilling angle, which can play a guiding role when ...
