Fast drilling type pulse retracting hand drill

Abstract

The invention relates to a processing tool, in particular to a fast drilling type pulse retracting hand drill. The fast drilling type pulse retracting hand drill comprises a support; a main shaft is rotatably connected to the support; a driving bevel gear is arranged on the main shaft in a sleeving manner; a driving disc is arranged on the support; the driving disc is rotatably connected with the support through a rotating shaft; the edge of the driving disc is provided with driving teeth which are meshed with the bevel gear; a clutch mechanism is arranged at the rotating shaft; a reverse rotating mechanism is arranged between the rotating shaft and the driving bevel gear; the end face, close to the driving bevel gear, of the support is provided with a section of pulse bulge; and the end face, close to the support, of the driving bevel gear is provided with a pulse lug. The fast drilling type pulse retracting hand drill has the beneficial effects that reverse rotating retracting with pulse frequency can be realized, hand shaking direction does not need to be changed, the hand shaking speed is stable, and the like.

Description

technical field [0001] The invention relates to a processing tool, in particular to a fast-drilling type pulse retract hand drill. Background technique [0002] In an existing type of manual drilling tool, by shaking the drive disc, the drive teeth on the drive disc are used to drive the main shaft to rotate, and then the drill bit is driven to rotate to realize drilling. Waste chips are generated during the drilling process, and the waste chips are easy to block the drill bit. It is necessary to reverse the drill bit to retract the tool to discharge the waste chips out of the hole, and then continue drilling. However, when this type of manual drilling tool needs to reverse the drill bit to retract the tool and remove chips, the drill bit can only be reversed by shaking the drive disc in reverse. That is to say, the drive disk needs to rotate clockwise several times to drill holes, then counterclockwise several times to retract the tool to remove chips, and then rotate cloc...

AI Technical Summary

Problems solved by technology

During the drilling process, it is necessary to change the direction of the drive disc repeatedly, and the driving force of the hand drill comes from the human arm muscles. Frequent changes in the direction of the hand will result in different directions of force applied to the arm muscles and joints, which will easily cause the hand drill to deflect.

Moreover, the frequent changes of hand-cranking movements make the muscles unable to form muscle memory, resulting in unstable hand-cranking speed and affecting the quality and efficiency of drilling.
