Electric drill capable of quickly adjusting rotating direction of drill rod

Abstract

The invention provides an electric drill capable of quickly adjusting the rotating direction of a drill rod and belongs to the technical field of electric drills. The electric drill comprises a mounting box, a first rotating shaft, a second rotating shaft, a third bevel gear, a motor, a drill rod, a first linking mechanism and a second linking mechanism, wherein the mounting box is internally provided with a mounting cavity; the first rotating shaft is rotationally arranged in the mounting cavity and is fixedly provided with a first bevel gear; the second rotating shaft is fixedly arranged in the mounting cavity; the second rotating shaft is rotationally provided with a second bevel gear; the third bevel gear is rotationally arranged in the mounting cavity; the first bevel gear is in meshed connection with the third bevel gear; the second bevel gear is in meshed connection with the third bevel gear; the first rotating shaft is fixedly connected with an output shaft of the motor; the drill rod is arranged in a first through hole of the second rotating shaft in a sliding manner; the first bevel gear can be in driving connection with the drill rod by the first linking mechanism; the second bevel gear can be in driving connection with the drill rod by the second linking mechanism. The electric drill provided by the invention can realize positive rotation and negative rotation of the drill rod without changing the rotating direction of the output shaft of the motor.

Description

technical field [0001] The invention belongs to the technical field of electric drills, and relates to an electric drill capable of quickly adjusting the rotation direction of a drill rod. Background technique [0002] An electric drill is a machine that uses a motor to drive a drill rod to rotate for drilling. [0003] The electric drill needs to switch between forward and reverse during the working process, so as to control drilling or pulling out. At present, most electric drills realize forward and reverse rotation by controlling the rotation of the motor output shaft, which requires frequent changes in the rotation of the motor output shaft. Such long-term use is likely to cause damage to the motor and affect work efficiency. Contents of the invention [0004] The purpose of the present invention is to solve the above-mentioned problems in the existing technology, and propose an electric drill that can quickly adjust the rotation direction of the drill rod, which can...
