Simple hand-operated puncher

Abstract

The invention discloses a simple hand-operated puncher and relates to the technical field of portable drilling machines. The simple hand-operated puncher comprises a drill rod and a drill bit and is characterized in that the middle of the drill rod is provided with a U-shaped rocking arm; the rocking arm is provided with a sleeve; one end of the drill rod is provided with a chuck, the drill bit is fixedly connected with the drill rod by virtue of the chuck; and the other end of the drill rod is provided with a grab handle. The simple hand-operated puncher is simple in structure, convenient to carry and use, and convenient in bit replacement, especially can be used for conveniently and easily punching and broaching an ammeter box and a wall under the condition of no power supply in the power construction process, is rapid and accurate, and can be used for greatly shortening the installation and fixation time of the ammeter box and improving the overall working efficiency; and the chuck is convenient to use, and the drill bit can be firmly chucked.

Description

technical field [0001] The invention relates to the technical field of portable drilling rigs, in particular to a puncher for installing an electric meter box. Background technique [0002] In the renovation process of the new rural electrification village, the installation of new meter boxes is one of the key points in the overall renovation process. However, the quality of the rural walls is uneven, and the gaps between the bricks are intricate. In order to achieve standardized installation, it is necessary to ensure that the walls in the same plane The height of the meter box is consistent, so the wall must be properly drilled and reamed. [0003] Electric drill is the most commonly used electric tool, but the drill bit of the electric drill is long, large in size and heavy in weight, and it is inconvenient to drill holes on the narrow, especially the reverse inner wall. The general electric drill is because the worker's direction is mastered when drilling. The imprecise...

Problems solved by technology

[0003] Electric drill is the most commonly used electric tool, but the drill bit of the electric drill is long, large in size and heavy in weight, and it is inconvenient to drill holes on the narrow, especially the reverse inner wall. The general electric drill is because the worker's direction is mastered when drilling. Inaccurate, easy to drill, affecting the quality of the drilling, and in the case of poor wall quality in rural areas, it may affect the large area of ​​the wall, so that the position of the entire row of holes needs to be changed, which wastes manpower and material resources and delays the construction period.

Usually, power supply problems are difficult to solve during rural power construction, so the use of electric drills is limited

[0004] Commonly used drill chucks are tightened with a key to clamp and fix the drill bit. If the locking force is not enough, the drill bit will rotate in the drill chuck, which is easy to wear the drill chuck.
