Rotating speed adjustable handheld perforating device

Abstract

The invention discloses a hand-held drilling device with adjustable rotating speed, which comprises a device main body, a drilling drill bit, a drill bit connecting rod, a bevel gear, a drill bit connecting rod fixing piece, a resistance piece, a connecting paddle, a trigger, a spring, and a wire protection layer , a rotating motor, a rotating shaft, a transmission rod and a transmission rod fixing piece, the right side of the device main body is provided with a drilling drill, the left side of the drilling drill is provided with a drill connecting rod, and the left side of the drilling connecting rod is connected with the bevel gear Connection, the lower side of the drill bit connecting rod is provided with a resistance sheet, and the left side of the resistance sheet is provided with a connecting paddle. The hand-held punching device with adjustable speed has the characteristics of small size, easy to carry and transport, and is equipped with a wire protection layer, which can ensure that the wire will not be damaged due to strong vibration or bumps during use and carrying, which greatly guarantees The service life of the device is extended, the work efficiency of the staff is greatly improved, the difficulty of work is reduced, and time and effort are saved.

Description

technical field [0001] The invention relates to the technical field of punching, in particular to a hand-held punching device with adjustable rotation speed. Background technique [0002] The adjustable speed handheld drilling device is a device that allows the user to hold the device for drilling operations and can freely adjust the speed. It refers to the use of tools that are harder and sharper than the target object through rotary cutting or rotary extrusion Methods, collectively referred to as machinery and equipment that leave cylindrical holes or holes on the target, also known as drilling rigs, punching machines, drilling machines, through-hole machines, etc., to achieve the desired effect by drilling precision parts, Drilling machines include semi-automatic drilling machines and fully automatic drilling machines. With the increase of human resource costs; most enterprises consider fully automatic drilling machines as the development direction. With the development o...

[0002] The adjustable speed handheld drilling device is a device that allows the user to hold the device for drilling operations and can freely adjust the speed. It refers to the use of tools that are harder and sharper than the target object through rotary cutting or rotary extrusion Methods, collectively referred to as machinery and equipment that leave cylindrical holes or holes on the target, also known as drilling rigs, punching machines, drilling machines, through-hole machines, etc., to achieve the desired effect by drilling precision parts, Drilling machines include semi-automatic drilling machines and fully automatic drilling machines. With the increase of human resource costs; most enterprises consider fully automatic drilling machines as the development direction. With the development of the times, the drilling of automatic drilling machines With the improvement of technology, the advantages of using a fully automatic drilling machine to drill various metal molds, watch straps, watch straps, and jewelry are obvious. The existing drilling device is too large and inconvenient to carry and transport, which affects the efficiency of use.
