Balanced center drilling booster for handheld water drill

Abstract

A balanced center drilling booster for a handheld water drill consists of seven parts, namely a strong pressure sealing dirt collector and base (1), a mounting hole position centering pile (3), a booster centering pile (8), a balanced center roller booster drilling mechanism (2), a quick operation adjusting mechanism (7), a reusable expansion pipe (112) and a mounting screw (10). Upgrading is realized on the basis of a strong pressure sealing dirt collector in the prior art, three overhead bridge pier-type centering piles (3) and (8) are arranged around the periphery of a large-belly soft dirtcollecting cover (6) by using a pressing plate type strong-pressure substrate, and the aperture opening-closing type balanced center roller booster drilling mechanism (2) is lifted above the openingof the dirt collecting cover. The balanced center drilling booster for the handheld water drill is still the category that people prefer to use the handheld water drill to drill holes in a traditionalway, but the balanced center drilling booster integrates high-level sealing dirt collection and automatic balanced center drilling in any drill barrel specification, and changes fatigue and labor-wasting manpower propulsion drilling to the new level that a drill barrel is sucked into a wall for hole forming. The balanced center drilling booster also has one advantage that since a roller wheel centralizes the balanced center of the drill barrel, the hole is quite smooth and straight, the drill is not clamped, and pursuing of anti-reaction-torque safety is improved by one level.

Description

Technical field [0001] A weighing center drilling booster for hand-held rhinestones. It is a patent application number 201910652559.5 for hand-held rhinestones. On the basis of a strong pressure sealed sewage collector, it uses three centering piles viaducts to set up a weighing center on the sewage collector. Roller-assisted drilling mechanism, a new tool appeared. It is still the category of hand-held rhinestone drilling that people traditionally like to use, but it already integrates high-level sealing and dirt collection, automatic adjustment of the center hole of any drill barrel specification, and fatigue and tiring manpower to push the hole for the feeling of the drill barrel. The new realm of being sucked into the wall into a hole. There is another advantage because there are rollers to right the center of the drill barrel. The hole is smooth and straight without jamming. The pursuit of anti-torque safety has been improved by one level. [0002] technical background [00...

AI Technical Summary

Problems solved by technology

Most of the air-conditioning drilling operations are small-diameter drilling, and the reaction torque is still easy to control. The majority of operators need a low-priced, hand-held rhinestone within the scope of the customary concept, and easily acceptable small specifications such as below 71 mm, safe and super Lightweight and portable drilling booster comes out
