Drilling tool penetrating hole puncher

Abstract

The invention provides a drilling tool penetrating hole puncher, and belongs to the technical field of hole punching instruments. The hole puncher structurally comprises a base and a supporting column, the base is horizontally arranged, the supporting column is perpendicular to the base and is fixedly connected to the center of the base, the lower segment of the supporting column is a solid cylinder segment with the round cross section, the solid cylinder segment of the supporting column is in penetrating connection with a lower position bearing disc, an action disc is arranged above the lowerposition bearing disc, a supporting force spring is arranged between the action disc and the lower position bearing disc, a drilling tool is arranged in a drilling tool configuration hole, a solid square column segment is in penetrating connection to a sliding hole in a motor base, a motor is arranged on the left side of the motor base, the motor is connected with a battery, an output shaft of the motor is coaxially and fixedly connected with a power output head, and the bottom end of the power output head is provided with a power key matched with a power access key groove of a drilling toolpower joint. The switchable action disc is used, the lower position bearing disc matched with the action disc is used, a part to be perforated is punched, according to the punching specification, thespecification of the drilling tool can be switched, and rapid switching is facilitated.

Description

technical field [0001] The invention relates to the technical field of punching instruments, in particular to a drilling tool piercing and punching device. Background technique [0002] Generally, most of the hole openers in the prior art commonly used in daily life adopt a hinge structure, such as the hole opener for paper pages adopts the hinge form, and the belt belt hole opener adopts the form of hand-held pliers. The torque of this type of hole saw is mostly based on the lever principle of the body design to realize the hole opening action. Its short moment arm and small torque can provide limited hole opening force, and in many cases it cannot meet the needs of hole opening, or even complete the hole opening action, and cannot completely open the hole. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a drilling tool piercing and punching device. [0004] The technical solution ...

AI Technical Summary

Problems solved by technology

The force arm is short and the torque is small, which can provide limited force for opening holes. In many cases, it cannot meet the needs of opening holes, or even complete the opening action, and cannot completely open holes.
