An electric drill with a square base

Abstract

The invention discloses an electric drill with a square base seat. The electric drill comprises a square base seat, wherein supporting cross beams are arranged in the square base seat; two ends of thesupporting cross beams are connected with the square base seat in a sliding manner; first sliding frames and second sliding frames are arranged between the electric drill and the supporting cross beams; the second sliding frames are connected with the supporting cross beams in a sliding manner; the first sliding frames and the second sliding frames are in sliding connection; and the electric drill is mounted on the first sliding frames. In the drilling process, the electric drill is fixed on the first sliding frames, then the square base seat is placed in a foundation pit, the front ends of the supporting beams are adjusted up and down, and the first sliding frames are moved left and right along the second sliding frames, so that a drill bit of the electric drill is aligned with a hole position, the adjustment of the bit position is convenient, the practicability is good, and meanwhile, workers can drill conveniently, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of electric drill drilling, in particular to an electric drill with a square base. Background technique [0002] The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, drives the working device through the transmission mechanism, and drives the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. . [0003] When the existing electric drill is drilling, especially when drilling on the side wall of the foundation pit, the user needs to adjust the horizontal position of the drill bit by himself. Usually, due to lack of experience, the sliding position of the drill bit is inaccurate and other problems, resulting in the drilling position. failed. Contents of the invention [0004] The purpos...
