Novel wall tube punching tool

Abstract

The invention relates to a novel wall tube punching tool, a plunger chip is arranged in a hole of a guide column, and external threads at the lower end of a guide rod are screwed in internal threads of the guide column, and a punching needle is tightly fixed; and then a steel ball is arranged in an inner hole of an upper sleeve, and an assembly which integrates the plunger chip, the guide column and the guide rod is arranged, and after a spring is sheathed outside the assembly piece which integrates the plunger chip, the guide column and the guide rod, an upper sleeve and a lower locating sleeve are connected into one body by the internal and external threads; in order to have better guiding function, a proper clearance exists between an outer circle a of the guide rod and an inner hole of the upper sleeve, and a gap exists between the outer circle of the guide column and an inner hole b of the lower locating sleeve; when in use, a V-shaped button of the lower locating sleeve spans at the proper position of the tube wall and is knocked to a steel ball by a hammer, so as to punch a hole, and the punching needle with different diameter can be punched into the corresponding bore diameter.

Description

technical field [0001] The invention relates to a wall pipe punching tool, in particular to a novel wall pipe punching tool. Background technique [0002] In hardware decoration and mechanical and electrical maintenance, it is often necessary to make holes on some pipe fittings. At present, the main means of making through holes on pipe fittings is to adopt the method of drilling or directly punching with a punch. Although the quality of the hole is better by using the method of drilling, the use conditions are limited due to the need for a special power supply, especially not suitable for use anytime and anywhere in maintenance; the method of direct punching with a punch, although it can It is convenient to use anytime and anywhere, but the position of the punching hole is often not easy to fix. At the same time, because the punching force and punching direction are not easy to control, there are often recessed defects around the hole, and the punching quality is not good. ...
