A small precision directional blasting instrument

Abstract

The invention discloses a small precise directional blasting instrument, and belongs to the field of small precise blasting. The small precise directional blasting instrument comprises a fixed outer rod, a rotating main rod is movably sleeved with the interior of the left end of the fixed outer rod, the interior of the right end of the rotating main rod is in threaded connection with a rotating pair rod, a bottom seal rod is fixedly sleeved with the interior of the right end of the fixed outer rod, a protection long rod is fixedly arranged on the right side of the bottom seal rod, a positioning inclined rod is fixedly arranged on the right side of the protection long rod in an inclined manner, a fixed short rod is fixedly arranged on the right end of the positioning inclined rod, the interior center positions of the rotating pair rod, the bottom seal rod and the protection long rod are provided with corresponding through grooves, and a positioning groove is formed in the positioning inclined rod. The designated position can be directly drilled, the other positions are not damaged, and drilling work is more precise.

Description

technical field [0001] The invention relates to the field of small precision blasting, and more specifically relates to a small precision directional blasting instrument. Background technique [0002] In the actual precision blasting operation, because it is operated in some key small parts, it is impossible to use a large drill bit for operation, but when using a small drill bit, the entire drilling machine cannot be fitted to the operation interface due to the narrow working environment. When working in a place far away from the operation interface, the accuracy of the drilling cannot be guaranteed at this time. At this time, the device can be used to achieve precise positioning, and the device can also be used to simultaneously place the detonator, realizing the completion of multiple operations with one instrument , reduce the operation process, and reduce the occurrence of operation errors. Contents of the invention [0003] 1. technical problem to be solved [000...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem existing in the prior art that it is impossible to drill holes at fixed points inside the device and place the detonator at the same time during the precision blasting operation, the purpose of the present invention is to provide a small precision directional blasting instrument, which can realize precision blasting operations During the work, fixed-point drilling is carried out inside the device and the detonator is placed at the same time
