Drilling structure that can change the construction angle

Abstract

The invention discloses a drilling structure capable of changing the construction angle. The drilling structure capable of changing the construction angle comprises a drill bit (1) and is characterized in that the drill bit (1) is connected with an inner ring of a one-way thrust bearing (2), an outer ring of the one-way thrust bearing (2) is connected with the end of a first square tube (3) with the square section, the other end of the first square tube (3) is connected with a second square tube (4) in a sleeved mode, the two contact faces of the first square tube (3) and the second square tube (4) are respectively provided with a rotary shaft (5), the opposite sides of the first square tube (3) and the second square tube (4) are respectively hinged to a screw (6), the two screws (6) are connected through a nut post (7), an inner cavity of the first square tube (3) and an inner cavity of the second square tube (4) are respectively provided with a universal hinge (8) inside, one end of each universal hinge (8) penetrates through the one-way thrust bearing (2) and is connected with the drill bit (1), and the other end of each universal hinge (8) is connected with an output shaft of an electric drill.

Description

technical field [0001] The invention relates to an electric drill auxiliary structure, in particular to a drilling structure capable of changing the construction angle. Background technique [0002] When carrying out some constructions that require drilling, the hand electric drill is an essential construction tool. However, in some special areas (narrow or high altitude), due to the limitation of the angle, ordinary electric drills cannot complete the drilling construction with angles, resulting in some work cannot be completed, affecting the quality and progress of the project. At present, when drilling at such a special position or angle, a bendable drill bit is used, which can change the angle of the drill bit and output torque, but this drill bit can only rotate 90 degrees, and has a large Due to the limitations of the construction, it cannot fully meet the construction requirements, and its price is very expensive. Therefore need a kind of novel drill structure that ...
