Electric perforating device capable of preventing wall cracking

Abstract

The invention discloses an electric perforating device capable of preventing wall cracking. The electric perforating device comprises cutting blades, a thread, perforating columns, a stress seat, an outer connecting seat, a transmission mechanism, an engine seat, a handle, a trigger, a groove, a lug and an inner connecting seat. The electric perforating device has the beneficial effects that the outer connecting seat and the inner connecting seat are different in diameter, the perforating columns can be taken down when not used, and meanwhile connection of different-specification perforating columns and a power device is also convenient; the outer sides of the perforating columns are provided with screw holes, screw propulsion is achieved, propulsion force is increased, the propulsion state is coherent, and a wall is not damaged; the stress seat and the perforating columns are clamped and connected through the lug and the groove, thus the stress seat can be taken down conveniently after perforating work, and the perforating columns are taken out of the wall; the cutting blades are arranged at one ends of the perforating columns, thus resistance to the perforating columns when the perforating columns are propelled in the wall is smaller, deformation of the perforating columns is avoided very well, and service life of the perforating columns is prolonged; and the handle is arranged at the bottom of the engine seat, and manual operation is convenient.

Description

Technical field [0001] The invention relates to a perforating device, in particular to an electric perforating device capable of preventing wall cracking, and belongs to the field of construction machinery and equipment. Background technique [0002] Since ancient times, it has been said that clothing, food and housing are an important part of people's lives, and housing as one of them is also extremely important. With the development of science, most houses are now constructed of concrete. After the construction of the house is completed, it is often necessary to punch holes in the poured wall to facilitate the passage of water pipes or wires, so the punching device came into being. At present, most perforating devices mostly use columnar perforating columns to directly push the wall, squeeze the wall out, and realize wall perforation. This kind of drilling method is extremely easy to cause wall cracking, and workers are susceptible to the reaction force of the wall when they u...

Problems solved by technology

This kind of punching method is extremely easy to cause cracks in the wall, and workers are vulnerable to the reaction force of the wall when they use the punching machine to punch holes. This reaction force is easy to hurt the construction personnel and has a great impact on the wall drilling work.
